Objective: This study aimed to provide a comprehensive case analysis from a single center, with the objective of clarifying the optimal timing and recommendations for a preferred treatment strategy customized to the specific presentation of each type of supernumerary tooth identified in the research. Method and materials: A retrospective study was conducted on patients who presented with a supernumerary tooth and were treated interdisciplinarily at the clinic. Results: In total, 55 patients with 81 supernumerary teeth of the permanent dentition were analyzed, 30 males and 25 females. The dentition status of the patients was as follows: 31 patients with mixed dentition, no patients with primary dentition, and 24 patients with permanent dentition. The diagnosis of supernumerary tooth was primarily made by general or pediatric dental practitioners and/or orthodontists. Patients were then referred to maxillofacial surgeons for treatment decision. The timing of treatment was mainly determined by the oral surgeon, based on the recommendations of the other specialists involved. Cases involving maleruption or malalignment of permanent teeth required both surgical and orthodontic treatment. Patients over 9 years old were treated either under local anesthesia or sedation, whereas those under 9 years old were treated under deep sedation or general anesthesia. A comprehensive investigation of cases involved the utilization of CBCT at the supernumerary tooth site to facilitate treatment planning. There was a significant correlation between younger age and the preference for treatment under sedation or general anesthesia (P = .01, t test). Similarly, a strong association was found between younger age and the need for additional orthodontic treatment (P = .016, t test). Cases of surgical removal of a supernumerary tooth at a young age typically did not require orthodontic traction of the permanent tooth, in contrast to cases of late surgical intervention (patients over 11 years old), which often did necessitate such traction. There was a strong tendency for treating supernumerary teeth in the maxilla. The proximity of supernumerary teeth to vital anatomical landmarks significantly influenced treatment decisions. Patients with supernumerary teeth near the mental foramen or the inferior dental canal in the premolar area were exclusively placed under follow-up care (P = .002, Pearson chi-square test). However, in the maxilla, the proximity of supernumerary teeth to vital structures such as the floor of the nose and the incisive nerve did not affect the treatment approach, and those supernumerary teeth were mostly removed. Conclusions: A team approach for managing supernumerary teeth is recommended. The timing of treatment should carefully consider the advantages and disadvantages of early versus late intervention. Early surgical treatment in cases where eruption is disturbed might result in spontaneous eruption, eliminating the need for orthodontic traction of the permanent teeth. [ABSTRACT FROM AUTHOR]

ABSTRACT Objective Methods Results Conclusion To evaluate the frequency of tooth anomalies (TA) in the deciduous and permanent dentition of patients with nonsyndromic orofacial clefts (NSOC), both inside and outside the cleft area.The following databases were searched for the relevant literature: Cochrane, OVID, SciELO, Embase, Livivo, PubMed, Scopus, and Web of Science. The risk of bias was analyzed using the Joanna Briggs Institute. Fixed and random‐effects meta‐analysis was performed comparing the presence and absence of NSOC subtypes. The certainty of evidence was evaluated using the GRADE approach.Out of 1939 articles identified, after applying the inclusion and exclusion criteria, a total of 75 articles were included (46 cohort and 29 case–control), including 27,703 patients (16,450 with NSOC and 11,253 healthy controls) from 34 countries. The meta‐analyses revealed higher odds for tooth agenesis (ORNSOC: 3.72; p = 0.001) and macrodontia (ORNSOC: 8.04; p = 0.04) across the different cleft subtypes outside the cleft area compared with the control group in the permanent dentition, whereas the frequency of root dilaceration was significantly lower in nonsyndromic cleft lip only (NSCLO) (ORNSCLO: 0.38; p < 0.0001) and in nonsyndromic cleft lip and palate (NSCLP) (ORNSCLP: 0.44; 95% p < 0.0001). The results also demonstrated a higher risk of tooth agenesis (ORNSOC: 16.49; p < 0.0001), microdontia (ORNSOC: 17.14; p < 0.0001), macrodontia (ORNSOC: 10.41; p = 0.02), supernumerary tooth (ORNSOC: 10.03; p < 0.0001), and enamel hypoplasia (ORNSOC: 5.62; p < 0.0001) in the permanent dentition inside the cleft area of patients with NSOC. However, for the deciduous dentition, outside the cleft area, microdontia was the only TA significantly more frequent in patients with NSOC (ORNSOC: 6.24; p = 0.006) and nonsyndromic cleft palate only (NSCPO) (ORNSCPO: 8.45; p = 0.02) compared with the control group. TA associations varied across populations. In Europe, no significant associations were found for NSOC, while in Asia, strong associations were observed for NSCLP and NSCL ± P (ORNSCLP and NSCL±P: 139.19; p < 0.0001). In South America, significant associations were identified for NSCLP (ORNSCLP: 2.16; p < 0.0001), NSCL ± P (ORNSCL±P: 2.48; p < 0.0001), and NSOC (ORNSOC: 2.72; p < 0.0001). In North America, tooth agenesis was more frequent in NSCL ± P (ORNSCL±P: 4.75; p < 0.0001), though no significant associations were found for NSCLP or NSOC. In the cleft area, significant associations were observed in European populations for NSOC, including increased frequencies of tooth agenesis (ORNSOC: 19.57; p = 0.003) and supernumerary teeth (ORNSOC: 9.77; p < 0.0001). Asian populations showed similar patterns (ORNSOC: 19.23; p = 0.002), while no significant associations were noted in South America due to limited data. Root dilaceration remained less frequent in NSCLO (ORNSCLO: 0.38; p < 0.0001) and NSCLP (ORNSCLP: 0.44; p < 0.0001), with no associations identified for microdontia, taurodontism, supernumerary tooth, impacted tooth, or transposition.The results confirm a higher frequency of TA in the permanent dentition of patients with NSOC compared to controls, regardless of cleft subtype. However, significant differences were observed depending on whether the TA occurred inside or outside the cleft area. Although only a limited number of studies were included, microdontia was the only TA significantly more prevalent in the cleft area of patients with NSOC in the deciduous dentition. Variations in the frequency of TA across populations highlight the complex interplay of genetic, environmental, and methodological factors influencing these associations. Despite these findings, the quality of the existing evidence is moderate, with limitations stemming from small sample sizes, methodological variations, and study heterogeneity. These results emphasize the importance of tailored dental management and early intervention strategies for individuals with different cleft subtypes to effectively address and mitigate the impact of these tooth anomalies on oral health and development.

Background: Mesiodens usually lead to the malposition and abnormal morphology of maxillary central incisors. Aim: To evaluate the detrimental effects of single unilaterally impacted mesiodens on the three‐dimensional positions and morphology of the maxillary central incisor using cone‐beam computed tomographic (CBCT) examinations. Design: A total of 321 patients aged 5–17 years with single unilaterally impacted mesiodens were included and divided into two groups: mixed dentition group (5–10 years) and early permanent dentition group (11–17 years). CBCT data for these patients were retrospectively analyzed to compare the inclination, rotation, angulation, and morphology of maxillary central incisors between the affected and contralateral control sides. The morphology, orientation, and spatial location of mesiodens were also assessed. Results: Central incisors on the affected side showed significant palatal crown inclination, shorter root, shorter tooth, and greater crown‐to‐root ratio in both groups, whereas significant mesial crown angulation was only observed in the mixed dentition group. Conclusion: Impacted mesiodentes result in the displacement and impaired root development of central incisors, strongly suggesting timely clinical management of these abnormal teeth, such as the early removal of mesiodens and orthodontic treatments.

Background: Supernumerary teeth, defined as extra teeth beyond the normal series of dentition, can appear anywhere in the dental arch. They may present as solitary or multiple, unilateral or bilateral, and can be either erupted or impacted. Rarely, supernumerary teeth are found in ectopic locations outside the dental arches, such as the nasal cavity, inferior nasal conchae, maxillary sinus, ethmoid sinus, or skull. To our knowledge, only two cases of supernumerary teeth in the horizontal plate of the palatine bone have been reported globally in the literature. This case represents the third known instance. Case presentation: A 10-year-old boy presented to the Oral and Maxillofacial Surgery outpatient department (OPD) with his parents, reporting a bony hard swelling on the palate that had been present for three years. The swelling was asymptomatic, with no associated pain or discomfort. Clinical examination revealed a non-tender, bony hard swelling on the midline of the posterior hard palate, with healthy overlying mucosa. A non-contrast computed tomography (NCCT) scan of the face confirmed the presence of an impacted supernumerary tooth in the middle of the horizontal plate of the palatine bone, with the crown oriented posteriorly and the root anteriorly. Surgical extraction was performed under general anesthesia. A palatal crevicular incision was made from the right second molar to the incisive papilla, and a full-thickness mucoperiosteal flap was raised. The impacted supernumerary tooth was located, the overlying bone was removed, and the tooth was extracted in its entirety. The flap was then closed primarily. Postoperative care included antibiotics, analgesics, and daily dressing for five days. The healing was uneventful, with no complications observed during the one-year follow-up. Conclusion: In cases of swelling in the posterior hard palate, an impacted supernumerary tooth should be considered in the differential diagnosis. Although extraction is the preferred treatment, when supernumerary teeth are located near vital structures and are asymptomatic, close observation with periodic radiographic monitoring is a reasonable management option.

Background/Objectives: The most common form of supernumerary teeth is represented by the mesiodens. Very often, they are impacted, usually palatially, but can be found buccally or between the roots of the permanent central incisors. Their position can be normal, inclined, or inverted. In the possible case where the impacted mesiodens crown is oriented upwards towards the nasal cavity, they are called inverted mesiodens. The inverted mesiodens are mainly asymptomatic, and the main diagnostic methods are radiological, especially CBCT. Methods: This paper presents the intraoral approach through the nasal floor as a very reliable method for the surgical removal of inverted mesiodens. We report a protocol, including the diagnosis process, criteria for choosing this surgical approach, and description of the surgical procedure. Preoperative CBCT is mandatory for diagnosis and choice of the surgical approach. This is chosen based on measurements on the cross-sectional view of the CBCT investigation and is in compliance with our criteria related to the appropriate surgical approach. Results: Using this approach, the mesiodens were extracted without intraoperative or postoperative complications or accidents, and operating times were relatively short. Conclusions: The intraoral approach through the nasal floor for surgical removal of inverted mesiodens satisfies all the conditions to be a predictable, safe, and time-efficient technique. It has its limitations, mainly regarding the surgical skills of the operating team. The cone–beam computed tomography (CBCT) has a fundamental role in the diagnosis and treatment of included mesiodens. [ABSTRACT FROM AUTHOR]

Cleidocranial Dysplasia (CCD) is a rare genetic disorder characterized by skeletal abnormalities and dental anomalies, primarily caused by variants in the RUNX2 gene. Understanding the spectrum of RUNX2 variants and their effects on CCD phenotypes is crucial for accurate diagnosis and management strategies. This systematic review aimed to comprehensively analyze the genotypic and phenotypic spectra of RUNX2 variants in CCD patients, assess their distribution across functional regions, and investigate genotype–phenotype correlations. This review included 569 reported variants and 453 CCD patients from 103 articles. Of 569 variants, in-frame variants constituted 48.68%, while null variants accounted for 51.32%. Regarding locations, RUNX2 variants were predominantly located in the RHD (55.54%), followed by PST (16.34%), NMTS (6.33%), QA (4.75%), VWRPY (1.23%), and NLS (1.41%) regions while 10.19% were in non-coding regions. In-frame variants occurred primarily in the RHD (90.97%), while null variants were found across various regions of RUNX2. Data analysis revealed a correlation between variant location and specific skeletal features in CCD patients. Missense variants, predominantly found within the functionally critical RHD, were significantly associated with supernumerary teeth, macrocephaly, metopic groove, short ribs, and hypoplastic iliac wings compared to nonsense variants. They were also significantly associated with delayed fontanelle closure, metopic synostosis, hypertelorism, limited shoulder abduction, pubic symphysis abnormalities, and hypoplastic iliac wings compared to in-frame variants found in other regions. These findings underscore the critical role of the RHD, with missense RHD variants having a more severe impact than nonsense and other in-frame variants. Additionally, in-frame insertions and deletions in RUNX2 were associated with fewer CCD features, compared to missense, frameshift, and nonsense variants. Null variants in the NLS region exhibited weaker associations with delayed fontanelle closure, supernumerary teeth, Wormian bones, and femoral head hypoplasia than variants in other regions. Moreover, the NLS variants did not consistently alter nuclear localization, questioning the role of NLS region in nuclear import. In summary, this comprehensive review significantly advances our understanding of CCD, facilitating improved phenotype-genotype correlations, enhanced clinical management, and a deeper insight into RUNX2 functional domains. This knowledge has the potential to guide the development of novel therapeutic targets for skeletal disorders. [ABSTRACT FROM AUTHOR]

Background: Congenitally missing permanent canines (CMPC) have a significant impact on function and aesthetics. The prevalence is low, and the availability of rigorous studies on this issue in China is limited. This study was designed to investigate the prevalence and distribution of CMPC in patients and concomitant anomalies. Additionally, we aimed to compare the prevalence of CMPC between two age groups. Methods: A total of 10,447 patient's panoramic radiograph (PR) images from August 2021 to December 2023 were reviewed and data regarding the location and number of CMPCs were recorded. Age and gender were obtained from the clinical records. Additionally, concomitant anomalies such as persistent primary canines, congenitally missing other permanent teeth, supernumerary teeth and microdontia were also recorded in patients with CMPC. 10,447 patients were divided into two groups: group A (< 121 months of age) and group B (≥ 121 months of age) to record the number of patients with CMPC. The data were presented as counts (n) and percentages (%), and statistically analysed using the Chi-square test. Results: The average age of patients with CMPC was 9.2 years, with a prevalence of 0.69% (n = 72). The difference between genders was not statistically significant (p = 0.950). The prevalence of CMPC in group B (1.08%, 26/2400) was significantly greater than that in group A (0.57%, 46/8047) (p = 0.008). 89.42% (93/104) of the missing permanent canines had visible primary canines in patients. CMPC were more likely to occur in the maxilla (91.67%) than in the mandible (6.94%) (p<0.001). No significant difference was found between the left and right sides (p = 0.844). With respect to concomitant anomalies among those with CMPC, 22 patients had 58 congenitally other permanent teeth missing, 3 patients had 3 supernumerary teeth, and 12 maxillary lateral incisors from 7 patients presented with microdontia. Conclusions: The prevalence of CMPC was 0.69%. CMPC were more likely to occur in the maxilla in the presence of persistent primary canines and were not influenced by gender or side. Early panoramic radiographs can improve the detection rate of CMPC, thereby facilitating prompt intervention and timely management. [ABSTRACT FROM AUTHOR]

The root canal systems of maxillary first molar (MFM) and maxillary second molar (MSM) variations represent a clinical challenge for endodontists, especially the prevalence of fused C-shaped roots. Having a thorough knowledge of root canal configuration is an extremely important point for a successful root canal treatment to avoid missing extra canals. The aim of this article was to present 2 cases of maxillary molar with an unusual C-shaped configuration diagnosed during root canal retreatment/treatment and conduct a literature review of the MFM and MSM anatomy. Case 1 reports that three separate palatal root canals fused into a C-shaped configuration in the MFM, which with an enamel pearl in the furcation, was classified as Type D and first reported in MFM. Case 2 reflects the fusion of all three buccal canals of the MSM into a C-shaped configuration that finally formed an apical foramen with a supernumerary tooth, and the configuration was Type B. Evaluation at an 18-month and a 9-month recall revealed that two patients were symptom-free after the conduct of a non-surgical retreatment/treatment, and the X-ray revealed normal periapical tissue. In addition, the thickness of the Schneiderian membrane due to odontogenic maxillary sinusitis returns to normal after an effective retreatment in case 1. These reports serve to remind endodontists of the importance and complexity of anatomical variations, which should always be considered when formulating an effective root canal treatment plan. The combined use of cone-beam computerized tomography (CBCT) and a dental operating microscope (DOM) will be profitable to locate and identify extra canals when a periapical radiograph shows signs of an unusual canal morphology.

Background: Supernumerary teeth numerical anomalies and the early diagnosis of supernumerary teeth is very important to avoid potential complications. The study aim was to determine the prevalence, occurrence, and characteristics of supernumerary teeth among the Arabian population. Methods: A retrospective radiographic study was performed using panoramic radiographs of patients attending a teaching hospital from January 2018 to December 2020. Only healthy patients with clear radiographs were included in the study, and patients with syndromes, cleft lip, and palate, and unclear radiographs were excluded from the study. The details include the patient's age and gender, supernumerary tooth number, location, orientation, and position. Only a single examiner was involved in the data collection and analysis. Results: Overall, 38 (2%) patients were observed with 47 supernumerary teeth. Among them, 76% were males and 24% were females, with a mean age of 16.1 ± 9.7 years. Mesiodens (87%) are the common type of supernumerary tooth, and the majority of the supernumerary teeth were impacted (66%). The majority of the patients presented with a single supernumerary tooth, while 24% of the patients presented with two supernumerary teeth. Sixty percent of the supernumerary teeth were conical in morphology, followed by a tuberculate morphology. In the study population, most of the supernumerary teeth were normal in orientation. Conclusions: The prevalence of supernumerary teeth was 2%. Among them, the majority were observed at the anterior region of the maxillary arch with a conical shape of normal orientation. The gender-based comparison of location, orientation, morphology, eruption, and number of supernumerary teeth showed male predilection. [ABSTRACT FROM AUTHOR]

BACKGROUND: Morphological and structural abnormalities are common dental anomalies. Identifying DA and determining their prevalence can play an important role in reducing the risk of surgical intervention and improving occlusion, leading to successful dental treatments. Thus, this study aimed to determine the prevalence of DA using panoramic radiographs (OPG) in Makkah, Saudi Arabia according to gender. MATERIALS AND METHODS: A retrospective radiographic investigation was performed, and the digital OPG of 923 patients (age range, 8–27 years) were collected. Records were collected from patients admitted at a government hospital in Makkah between January 2020 and DA in terms of tooth shape (microdontia, macrodontia, gemination, and fusion), number (supernumerary and congenitally missing teeth), and position (impaction and ectopic eruption). Several other abnormalities, such as ankyloses, dens in dents, dilacerations, and taurodontism, have also been reported. Digital radiographs from patients were systematically evaluated to diagnose each radiograph with consistent screen brightness and resolution. RESULTS: The most prevalent DA were impaction (53.8%), hypodontia (13.6%), microdontia (8.2%), and ectopic eruption (6.7%). Taurodontism was observed more frequently in male compared to female (7.5% and 2.2%, respectively). However, there was no significant difference between gender in the distribution of other DA. CONCLUSION: This study found that 27.8% of the Saudi population of Makkah city have DA. Clinical examination and radiographic evaluation are crucial for providing the proper treatment for patients seeking dental treatment. [ABSTRACT FROM AUTHOR]

Objective To retrospectively analyze the epidemiological characteristics of supernumerary teeth in patients aged 4-18 years old and the influencing factors on the selection of anesthesia methods, and to provide a reference for the selection of anesthesia plans for children and adolescents with supernumerary teeth. Methods This study is a retrospective study approved by the Institutional Ethics Committee. Based on clinical electronic medical record system and cone beam CT (CBCT) data, a retrospective analysis was conducted on 2 210 patients 4-18 years of age who underwent supernumerary tooth extraction at the School of Stomatology, Fourth Military Medical University from August 2019 to July 2021. Inclusion criteria: ① Age 4-18 years old; and ② The American Society of Anesthesiologists (ASA) classifies anesthesia into grades I-II; and ③ Have complete oral and anesthesia case records and relevant imaging data. Exclusion criteria: ① Incomplete medical records or unclear imaging data; and ② Patients with ASA grade II or above. Patients’ gender and age, the number of supernumerary teeth, arch, location, orientation, eruption status, reason for appointment, anxiety level, degree of cooperation, anesthesia method, and other relevant information were collected and statistically analyzed. Results A total of 1 865 eligible patients were included, with an average age of (8.9±3.2) years old. There were more male patients (71.37%, 1 331 cases) than female patients (28.63%, 534 cases) (P < 0.001), with a gender ratio of 2.49:1. The majority of supernumerary teeth were single (75.97%, 1 417/1 865), primarily located in the maxilla (97.2%, 1 812/1 865) and the anterior dental region (94.2%, 1 757/1 865), and in a centric position (77.3%, 1 442/1 865). The majority of patients with erupted supernumerary teeth were active in seeking treatment (97.67%, 335/343). Patients with supernumerary teeth located in the maxilla and mandible bones, as well as in the nasal floor, were mainly referred to the department for diagnosis, accounting for 94.38%(1 361/1 442) and 90.00% (72/80) (χ2=1 363.24, P < 0.001), respectively. Regarding anesthesia methods, the largest proportion of patients received nitrous oxide sedation-assisted local anesthesia or nerve block anesthesia, accounting for 38.07% (710/1 865), followed by local anesthesia, accounting for 35.23% (657/1 865). The proportion of patients receiving midazolam intravenous sedation with local anesthesia or nerve block anesthesia and general anesthesia was relatively small, accounting for 20.86% (389/1 865) and 5.84% (109/1 865). Patients 13-18 years of age with supernumerary teeth in the mandibular and posterior regions and without anxiety had the highest proportion of local anesthesia use (P < 0.001). In contrast, patients who had supernumerary teeth located at the base of the nose (50%), severe anxiety (94.12%), and poor cooperation (98.18%) had the highest proportion of general anesthesia use (P < 0.001). There was no significant difference (P = 0.35) in the incidence of intraoperative and postoperative complications after the extraction of supernumerary teeth. However, the proportion of anesthesia-related complications, such as dizziness, coughing, and respiratory depression, occurring in patients who received general anesthesia was higher than local anesthesia, accounting for 3.81% (P = 0.006). Conclusion There is a gender difference in the incidence of supernumerary teeth in patients 4-18 years of age, with a higher prevalence in males. The majority of supernumerary teeth are single and located in the maxillary anterior region, predominantly in a centric position. Patients whose teeth had erupted were more likely to seek medical treatment voluntarily, while patients with supernumerary teeth located in the maxilla and mandible bones, as well as in the nasal floor were more likely to be referred to the department. Patients with high levels of anxiety, poor cooperation, young age, multiple teeth, and high surgical difficulty were more inclined to choose general anesthesia.

Abstract Background Pattern of dental anomalies encountered in cleft patients shows subtle signs of genetic involvement. This study aimed to evaluate the prevalence and pattern of tooth agenesis and supernumerary teeth in Thai cleft population according to the cleft type. Methods Data collected from patients with cleft lip and palate, who had been treated at Tawanchai Cleft Center, Khon Kaen University, Thailand, available during year 2012–2022, were investigated. Records from 194 patients with non-syndromic clefts met the inclusion criteria. Standard dental records, and at least either orthopantomogram (OPG) or cone beam computed tomography (CBCT), were examined. Statistical analysis was performed using chi-square and binominal test (p ≤ 0.05). Results Prevalence of tooth agenesis was higher (77.3%) than that of supernumerary teeth (5.7%) and was more common in bilateral cleft lip and palate (BCLP) (88.1%) than in unilateral cleft lip and palate (UCLP) (72.6%) (p = 0.017). The upper lateral incisor was more frequently affected (46.4%), followed by the upper second premolar. The number of missing teeth observed on the left side was significantly higher. Patients with left UCLP (ULCLP) had the highest prevalence of tooth agenesis. A total of 41 tooth agenesis code (TAC) patterns was found. The prevalence of supernumerary teeth was comparable with 6.6% of ULCLP, 5.1% of BCLP, and 4.5% of URCLP. Tooth-number anomalies were observed more often in the BCLP and were most likely to occur on the left side of the maxilla. Both types of anomalies could be featured in a small proportion of cleft patients. Conclusions More than half of the patients with non-syndromic cleft lip and palate in this study, presented with tooth-number anomalies. Tooth agenesis was approximately 10-time more prevalent than supernumerary teeth. Tooth agenesis was likely to appear on the left-side of the maxilla regardless of the laterality of the cleft.

Background: The extraction of impacted supernumerary teeth requires precision and accuracy to mitigate iatrogenic damage to crucial anatomical structures during dental surgical procedures, thereby enhancing postoperative healing outcomes. Dynamic navigation systems (DNS) have been applied in dentistry in maxillofacial fractures, orthognathic surgery, root canal treatment, and endodontic surgery. Case Report: A 22-year-old female patient visited our department to assess and manage unerupted third molars. An initial cone beam computed tomography (CBCT) scan was obtained. Radiographic and clinical examinations showed the presence of a supernumerary tooth impacted on the lingual side between the root of the lower second premolar and the lower first molar and bilateral lower impacted third molars. The patient agreed to removal of these teeth. To perform the treatment planning of this case and to guide the surgeon intraoperatively, a dynamic surgical navigation system was recommended for surgical extraction of a supernumerary tooth and the impacted third molars. Conclusions: The dynamic navigation system coupled with a high-speed contra-angle handpiece for the extraction of supernumerary teeth is a personalized, digitally-driven, precise, minimally invasive, and efficient treatment approach. In this case, the DNS and the high-speed contra-angle handpiece were seamlessly integrated to facilitate visualization of the surgical procedure, thereby safeguarding of surrounding vital anatomical structures while enhancing patient comfort.

Background: The prevalence of supernumerary teeth is increasing in modern dental practice. However, the presence of multiple supernumerary teeth should be further investigated. Proper diagnosis of an underlying syndrome might save the patient from future health hazards through early diagnosis and optimal follow‐up screening. Case Presentation: A 13‐year‐old female patient presented with multiple retained deciduous teeth and delayed eruption of permanent teeth. Although the medical and family history of the patient did not raise any concerns, the clinical and radiographic examinations yielded intriguing findings. The patient presented with a total of 11 supernumerary teeth, which impeded the normal eruption of permanent dentition in addition to the presence of retained deciduous teeth. Additional clinical and laboratory investigations were conducted in response to the case's complexity, resulting in the diagnosis of Trichorhinophalangeal Syndrome (TRPS) Type I. The patient underwent a precise treatment plan and then was followed up for 6 months postoperatively to monitor the eruptive movement of the permanent teeth. Conclusion: When a syndrome is the underlying cause, monitoring unusual cases, such as those with multiple supernumerary teeth, can be lifesaving or aid in the early diagnosis of more serious complications.

Purpose: To determine the prevalence of malocclusion in Portuguese preschool children, to characterise occlusion in the deciduous dentition, and to study the relationship between malocclusion, sex, and age. Methods: This cross-sectional study included 3–6 years old children, from 25 randomly selected kindergartens from the Lisbon district. Data were collected through an oral examination. Malocclusion was defined as the presence of any type of occlusion anomaly (anterior crossbite, edge-to-edge, increased overjet, open bite, deep overbite, posterior crossbite, scissor bite), spacing anomaly (crowding), or dentition anomaly (supernumerary teeth, agenesis, malformations). Canine class, terminal plane of the deciduous second molars and type of Baume arch were also recorded. Statistical analysis included descriptive and chi-squared test (α = 0.05). Results: The sample included 426 children with a global prevalence of malocclusion of 60.6%. Occlusion anomalies were the most prevalent (59.2%), the most frequent being deep overbite (27%), increased overjet (22.1%) and posterior crossbite (14.1%). Crowding had a prevalence of 1.6% and agenesis of 1.4%. Class I canine (57.3%), straight second molar terminal plane (60.1%) and type I Baume arch (53.3%) were the most common. The mean overjet was 2.6 mm (sd = 2.1) and the mean overbite was 2.2 mm (sd = 2.1). Age was associated with the presence of occlusion anomalies (p = 0.03), and increased overjet prevalence was found to be higher in girls (p = 0.03). Conclusions: The prevalence of malocclusion was high, with occlusion anomalies being the most prevalent. It is important to identify modifiable risk factors associated with malocclusion to prevent this condition in both the deciduous and permanent dentitions. [ABSTRACT FROM AUTHOR]

Objectives: To explore the association between third molar agenesis and supernumerary tooth formation in a white‐European population. Materials and Methods: A record review in various orthodontic clinics identified 380 eligible white‐European individuals, half of whom had non‐syndromic permanent supernumerary teeth (122 males and 68 females, totalling 244 supernumerary teeth; median age: 13.1, iqr: 1.5 years), and the other half were age‐ and sex‐matched controls with full dentition, excluding the third molars. Tooth sequences were identified in panoramic radiographs. Results: In the supernumerary group, approximately 80% of the individuals had a single supernumerary tooth, followed by those having two additional teeth. In both groups, there was no sexual dimorphism in third molar agenesis severity. The prevalence of third molar agenesis in the supernumerary group was similar to that of the control group (28/190 = 14.7% in both groups; p = 1.0). In total, 53 third molars were missing in the supernumerary group (n = 190) compared to 67 in the control group (n = 190; p =.862). The ratio of bilateral to unilateral third molar agenesis was significantly lower in the supernumerary group than in the control group (1.0 vs. 3.7, respectively; p =.026). Conclusion: The presence of supernumerary teeth did not significantly alter the likelihood of third molar agenesis or its severity. Bilateral third molar agenesis was considerably less prevalent in individuals with supernumerary teeth compared to controls. The present novel findings have important clinical and developmental implications. [ABSTRACT FROM AUTHOR]

Cleidocranial dysplasia (CCD) is a rare autosomal disorder characterized by multiple impacted supernumerary teeth sometimes accompanied by follicular cysts. These patients may be first noticed by the dentist because of esthetic problems or delayed eruption of teeth. The aim of the study was to emphasize the importance of early diagnosis of CCD as multiple impacted teeth can give rise to dentigerous cyst in later stages. Two case reports describe the patients having typical features of CCD with impacted teeth and one of them was radiographically diagnosed with multiple dentigerous cysts. Early diagnosis of CCD and its management of impacted teeth with a multidisciplinary approach helps in avoiding the functional and pathological problems associated with it which include difficulty in mastication and poor patient self-esteem.

Hyperdontia refers to an excess number of teeth past the expected number of teeth for an individual located in the mandible or maxilla. These extra teeth are often referred to as "supernumerary." This condition is a relatively uncommon, infrequent phenomenon scarcely documented in Ursidae globally, with only a handful of examples documented in literature. In 2008, an indigenous hunter harvested a grizzly bear (Ursus arctos) in Smithers, British Columbia, Canada. The bear exhibited 7 maxillary incisors, with a supernumerary tooth present. This observation serves as the first-ever record of the supernumerary dentition of the incisors in brown bears. [ABSTRACT FROM AUTHOR]

Background: Artificial intelligence (AI) based on deep learning (DL) algorithms has shown promise in enhancing the speed and accuracy of dental anomaly detection in paediatric dentistry. Aim: This systematic review aimed to investigate the performance of AI systems in identifying dental anomalies in paediatric dentistry and compare it with human performance. Design: A systematic search of Scopus, PubMed and Google Scholar was conducted from 2012 to 2022. Inclusion criteria were based on problem/patient/population, intervention/indicator, comparison and outcome scheme and specific keywords related to AI, DL, paediatric dentistry, dental anomalies, supernumerary and mesiodens. Six of 3918 initial pool articles were included, assessing nine DL sub‐systems that used panoramic radiographs or cone‐beam computed tomography. Article quality was assessed using QUADAS‐2. Results: Artificial intelligence systems based on DL algorithms showed promising potential in enhancing the speed and accuracy of dental anomaly detection, with an average of 85.38% accuracy and 86.61% sensitivity. Human performance, however, outperformed AI systems, achieving 95% accuracy and 99% sensitivity. Limitations included a limited number of articles and data heterogeneity. Conclusion: The potential of AI systems employing DL algorithms is highlighted in detecting dental anomalies in paediatric dentistry. Further research is needed to address limitations, explore additional anomalies and establish the broader applicability of AI in paediatric dentistry. [ABSTRACT FROM AUTHOR]

Background: To investigate how successfully the classification of patients with and without dental anomalies was achieved through four experiments involving different dental anomalies. Methods: Lateral cephalometric radiographs (LCRs) from 526 individuals aged between 14 and 22 years were included. Four experiments involving different dental anomalies were created. Experiment 1 included the total dental anomaly group and control group (CG). Experiment 2 only had dental agenesis and a CG. Experiment 3 consisted of only palatally impacted canines and the CG. Experiment 4 comprised patients with various dental defects (transposition, hypodontia, agenesis-palatally affected canine, peg-shaped laterally, hyperdontia) and the CG. Twelve sella measurements and assessments of the ponticulus posticus and posterior arch deficiency were given as input. The target was to distinguish between anomalies and controls. The CatBoost algorithm was applied to classify patients with and without dental anomalies. Results: In order from lowest to highest, the predictive accuracies of the experiments were as follows: experiment 4 < experiment 2 < experiment 3 < experiment 1. The sella area (SA) (mm2) was the most important variable in experiment 1. The most significant variable in prediction model of experiment 2 was sella height posterior (SHP) (mm). Sella area (SA) (mm2) was again the most relevant variable in experiment 3. The most important variable in experiment 4 was sella height median (SHM) (mm). Conclusions: Every prediction model from the four experiments prioritized different variables. These findings may suggest that related research should focus on specific traits from a diagnostic perspective. [ABSTRACT FROM AUTHOR]

Simple Summary: The dentition analysis in vertebrates has been a pillar for the development of the classic and alternative theories on the evolution of species. The early dentition pattern consists of numerous, similar, and simple conical teeth, which are typically repeated in each half of both the maxilla and mandible. In mammals, however, dentition is regionally differentiated according to the dental arch, with dietary specialization being the main evolutionary pressure that defines the number, size, and shape of teeth. The developmental failure of a tooth normally present (hypodontia) and duplication of teeth (hyperdontia) is a deviation from the typical dental formula; their analysis allows for determining the prevalence of some dental conditions and their role in the health status of populations. After examining a sample size of 970 skulls of a total of 1121 beavers (Castor canadensis) that were removed in invaded areas of Tierra del Fuego, two dentition anomalies were recorded: hypodontia and hyperdontia (0.41% in both cases). Beavers also presented artifactual tooth loss (0.30%), acquired tooth loss (0.61%), fractured teeth (0.41%), and caries (0.31%). These conditions occurred in all age classes, showing a female bias, and represent a precedent of dentition anomalies and dentition and cranial conditions in an exotic invasive mammal. The study of dentition anomalies and pathologies in wildlife contributes, together with other indicators, to understanding the relevance of some factors on the health status of populations. This has not been properly evaluated in invasive mammals. To test the feasibility of eradication, the government of Tierra del Fuego performed the eradication of beavers (Castor canadensis) from 2016 to 2018: 1121 animals were removed and 970 examined. These beavers were examined to analyze the incidence of dentition anomalies and other dentition and cranial conditions. The beavers presented two dentition anomalies: hypodontia and hyperdontia (0.41% in both cases), and for the first time, a dentition anomaly in the upper quadrants was reported. Beavers also presented artifactual tooth loss (0.30%) and acquired tooth loss (0.61%) but with low incidence. The presence of fractured teeth (0.41%) and caries (0.31%) occurred in all age classes, also with low incidence. The third molar tooth was the most affected, showing a female bias. The 0.93% of skulls had a cranial abnormality represented as a buccal curvature. Malocclusion cases also were recorded (0.51%). The low prevalence of dentition anomalies, fractured teeth, caries, and cranial abnormalities would not compromise the lifespan of beavers. These results leave a precedent of dentition anomalies and dentition and cranial conditions in an invasive mammal. [ABSTRACT FROM AUTHOR]

Background: External surface resorption is pressure-induced resorption and occurs on the external surface of the root, pressure exerted by impacted teeth, is common causes of external surface resorption. Predictive risk factors of impacted supernumerary tooth-associated root resorption (ISTARR) mentioned in this article include supernumerary teeth and patient factors. To investigate the risk factors of impacted supernumerary tooth-associated root resorption and predict the incidence of root resorption. Methods: This restrospective study enrolled 324 patients with impacted supernumerary tooth. All Cone-Beam Computed Tomography (CBCT) data and patient information were divided into two groups (without tooth root resorption and with root resorption). CBCT images and patient information (age and gender) of 133 patients had adjacent tooth root resorption and 191 did not. seven variables were analysed using binary logistic regression. Results: Individual analysis of potential risk factors showed that age, crown mesiodistal direction, root formation, and odontotheca of the impacted supernumerary tooth were associated significantly with ISTARR. Binary logistic regression showed that impacted supernumerary tooth with odontotheca (Odd Ratio = 2.926), the crown is in the middle (Odd Ratio = 1.446), located at the middle third of the adjacent tooth root (Odd Ratio = 1.614), complete root development (Odd Ratio = 1.334), and patient's age (Odd Ratio = 1.261) were significantly associated with ISTARR risk. Conclusions: The risk factors of root resorption can be detected and predicted early according to the features of supernumerary tooth and patient's age. Still, more prospective studies with larger sample size are needed to validate the result. [ABSTRACT FROM AUTHOR]

Objective: To investigate the incidence of accessory canals and the variation in root canal morphology of permanent mandibular incisors and canines in Pakistani population using Cone Beam Computed Tomography (CBCT). Methods: A cross-sectional study was conducted in University College of Dentistry, The University of Lahore, Pakistan after getting institutional ethical permission from January 2020 to September 2022. The data included records of 111 patients consisting of 444 permanent mandibular incisors and 222 permanent mandibular canines. Accessory root, root canals and Vertucci canal configuration for each tooth was recorded. Data analysis was done using SPSS v20. Descriptive statistics were calculated for each anatomical parameter. Chi-square test was applied to determine association of gender with the presence of accessory roots and root canals. Results: Among the 111 records evaluated, 48.6% were males and 51.4% were females. No accessory root was found in the central and lateral incisors. However, an accessory root was found in 4.9% of the canines. The incidence of accessory canals in the central incisors, lateral incisors and canines was 18.9%, 25.2% and 10.4% respectively. The most common canal configuration in teeth with accessory canals was Type-III, followed by Type-II and Type-V. Conclusion: None of the central or lateral incisor showed accessory root while it was detected in 4.9% canines. The frequency of accessory root canal was found to be 18.9%, 25.2% and 10.4% in central incisors, lateral incisors and canines respectively. The most common canal configuration was Type-I, followed by Type-III and Type-II. Type-V, VI and VII were less common. [ABSTRACT FROM AUTHOR]

APC is a tumor suppressor gene that exerts its effect through the regulation of the Wnt signaling pathway. Loss of function mutations of the gene are associated with familial adenomatous polyposis (FAP). Early diagnosis in FAP patients is essential to prevent the development of colorectal cancer. Extraintestinal manifestations often precede the formation of the polyposis; therefore, these manifestations may serve as a clinical indicator for the condition. The aim of this study was to assess genotype–phenotype associations between the location of APC mutations and various extraintestinal features, mainly focusing on osseous and dental anomalies. Analyses of our cases and the mutations available in the literature with these manifestations revealed that mutations in the N-terminal region (amino acids 1–~1000) of the protein are more frequently associated with only osseous anomalies, whereas dental manifestations are more prevalent in mutations in the middle region (amino acids 1000–~2100). In addition, supernumerary teeth were found to be the most common dental feature. Since dental abnormalities often precede intestinal polyposis, dentists have a crucial role in the early identification of patients at risk. [ABSTRACT FROM AUTHOR]

Teeth, either erupted or impacted, that exceed the normal count are known as supernumerary teeth. They can appear unilaterally or bilaterally, singly or in multiples, and may be located anywhere in both dental arches. Multiple permanent impacted supernumerary teeth are uncommon and are often associated to syndromes but can be idiopathic. The prevalence of nonsyndromic multiple supernumerary teeth is under 1%. Here, we present a rare case of nonsyndromic multiple supernumerary and permanent impacted teeth in a young female patient, who reported with no loss of deciduous teeth and no eruption of permanent teeth except the first maxillary and mandibular permanent molars. A panoramic radiograph showed several supernumerary and permanent impacted teeth in both maxillary and mandibular arches. The diagnosis of idiopathic hyperdontia was made on the basis of clinical features and radiographic examination, and the management strategy needs to be planned with a multidisciplinary approach.

ABSTRACT: Supernumerary teeth represent a significant dental anomaly that has a notable impact on the primary and early mixed dentition, potentially leading to pathological disturbances in the development of permanent dentition. Mesiodens specifically refers to an additional tooth (erupted/unerupted) present in the midline between the two central incisors. This article describes two cases involving the surgical extraction of inverted and impacted mesiodens by using a minimally invasive surgical approach in children. Early extraction of supernumeraries can offer the advantage of minimizing loss of eruptive potential, space loss, and midline displacement. The decision on the treatment plan should be primarily influenced by the position of the mesiodens and its proximity to the permanent incisors. [ABSTRACT FROM AUTHOR]

IMPACTION of teeth , *DECIDUOUS teeth , *SUPERNUMERARY teeth , *CUSPIDS , *AGE distribution - Abstract
ABSTRACT: Background: Impacted teeth have a low prevalence but exhibit a very uneven distribution. Among dental visits, impaction is one of the most common issues encountered. The causes of impaction can can vary from person to person, including factors such as a lack of calcium, retained deciduous tooth, or the presence of supernumerary teeth that interfere with the normal eruption pattern. The presence of impacted teeth can hinder the progress of orthodontic treatment. Therefore, understanding the prevalence of impacted teeth is crucial for effective treatment planning. This study aims to examine the prevalence of impacted teeth among dental patients in the southwest zone of Hyderabad. Materials and Methods: Panaromic radiographs taken in 2019 served as the basis for this crosssectional investigation. After reviewing 2,819 radiographs, data on patients with impacted teeth were collected. We analyzed the age and gender distribution of 40 individuals with impacted canine teeth to determine prevalence. Data were tabulated and analyzed using Excel. The sectors identified according to Ericson and Kurol were used to categorize the data. Frequency and percentage were used as statistical measures. Results: The study found that the most common type of impacted teeth was in males aged 20 and above (45%), followed by females at (40%). Among those aged less than 20, the prevalence was 12.5% in females and 2.5% in males. The data suggest that the majority of dental patients with impacted teeth were male and over the age of 20. Conclusion: The study concludes that impacted teeth are more prevalent in males over the age of 20 among dental patients in the southwest zone of Hyderabad. [ABSTRACT FROM AUTHOR]

Objective: Dental anomalies (DA) can affect paediatric patients' aesthetics, function, and psychological well-being. There is a lack of data about the prevalence of DA in children in Kuwait. This study aimed to investigate the prevalence and distribution of DA amongst schoolchildren aged 8 to 12 years. Methods: A retrospective study was conducted using panoramic digital radiographs of children who attended a single dental center. All radiographs were evaluated by 2 calibrated and trained examiners. Results: DA were present in 110 (20.1%) out of the 546 panoramic radiographs examined: 53.6% in females and 46.4% in males. The mean age of children with DA (9.83 ± 1.29) was similar to that of children with no anomalies (9.96 ± 1.46). The most prevalent anomaly was dental agenesis (9.3%), followed by taurodontism (6.6%) and ectopic eruption (EE, 2%). DA were more common in the maxilla (58.2%) compared to the mandible (41.8%, P = .042). Congenitally missing teeth were significantly more frequent in the mandible (56.9%) than in the maxilla (43.1%, P = .003). EE was significantly more common in the maxilla (90.9%) than in the mandible (9.1%, P = .024). Microdontia and root dilacerations were only present in males, whilst supernumerary teeth, transposition, and impacted teeth were noted in females only. Conclusions: The prevalence of DA amongst schoolchildren in Kuwait was considered to be relatively high. Certain DA were associated with gender. The significant prevalence of DA highlights the need for early diagnosis using panoramic radiographs, particularly during the ages of 9 and 10, in order to ensure effective patient management.

Abstract Background Cleidocranial dysplasia (CCD) is an autosomal dominant hereditary disorder. Besides skeletal abnormalities, CCD is often associated with dental complications, such as multiple supernumerary teeth and permanent teeth impaction or delayed eruption. Methods Supernumerary teeth of axial, sagittal and coronal CBCT view was characterized in detail and 3D image reconstruction was performed. Number and location of teeth, morphology of supernumerary teeth, positional relationship between supernumerary and adjacent permanent teeth, direction of supernumerary teeth in CCD patients were analyzed. Results The mean age of the 3 CCD patients in this study was 16.7 years. Among 36 supernumerary teeth, the majority of them were identified as apical side located and lingual side located. Normal orientation was the most common type in this study, followed by sagittal orientation, and horizontal orientation. Horizontal orientation teeth were all distributed in the mandible. Supernumerary teeth exhibited significantly shorter crown and dental-root lengths, as well as smaller crown mesiodistal and buccolingual diameters (P

Introduction: In orthodontics, the triage system is used to assess the preadolescents to rule out interventions needed earlier and to assess the nature of orthodontic problems as complex or moderate. The objective of this study was to determine the knowledge and awareness of orthodontic triage and its uses among dental healthcare professionals (DHCP). Materials and methods: A triage awareness questionnaire (TAQ) was formulated and validated as reliable by a panel of five orthodontic specialists which was then circulated online among 400 DHCP. The questionnaire consisted of nine sections that assessed the current knowledge and usage of orthodontic triage among the dental community. Frequencies and percentages were reported for all categorical variables. Chi-square was used to assess the association among the variables. Results: The response rate was 28.2% with the majority of participants being general dentists. Regarding the knowledge and use of triage, 40% of DHCP were only familiar with the word "orthodontic triage" while being unaware of how it works and 79% denied using orthodontic triage. Regarding the management of anomalies, 42% of DHCP preferred extraction as the management of supernumerary teeth (p = 0.013). Practitioners belonging to private setups performed visual inspection in growing patients for assessment of their facial features (p = 0.012). Clinicians with more than one year of experience referred young patients to orthodontic specialists for the management of crossbite (p = 0.024). Younger clinicians (25–35 years) with more than one year of experience referred adult patients to orthodontists for correction of their unesthetic smile (p = 0.013). Conclusions: This paper provides foundational data for the development of future policies and protocols supporting structured, evidence-based approaches to patient management via use of orthodontic triage. This study underscores the importance of targeted educational interventions to enhance understanding and implementation of orthodontic triage principles in clinical practice. Further probing is necessary to discern the disparity between understanding the orthodontic triage and effective employment of its components among practicing dental healthcare professionals.

Background: Usher syndrome (USH) encompasses a group of disorders characterized by congenital sensorineural hearing loss (SNHL) and retinitis pigmentosa (RP). We described the clinical findings, natural history, and molecular analyses of USH patients identified during a large-scale screening to identify quantitative traits related to ocular disorders in the SardiNIA project cohort. Methods: We identified 3 USH-affected families out of a cohort of 6,148 healthy subjects. 9 subjects presented a pathological phenotype, with SNHL and RP. All patients and their family members underwent a complete ophthalmic examination including best-corrected visual acuity, slit-lamp biomicroscopy, fundoscopy, fundus autofluorescence, spectral-domain optical coherence tomography, and electrophysiological testing. Audiological evaluation was performed with a clinical audiometer. Genotyping was performed using several arrays integrated with whole genome sequence data providing approximately 22 million markers equally distributed for each subject analyzed. Molecular diagnostics focused on analysis of the following candidate genes: MYO7A, USH1C, CDH23, PCDH15, USH1G, CIB2, USH2A, GPR98, DFNB31, CLRN1, and PDZD7. Results: A single missense causal variant in USH2A gene was identified in homozygous status in all patients and in heterozygous status in unaffected parents. The presence of multiple homozygous patients with the same phenotypic severity of the syndromic form suggests that the Sardinian USH phenotype is the result of a founder effect on a specific pathogenic variant related haplotype. The frequency of heterozygotes in general Sardinian population is 1.89. Additionally, to provide new insights into the structure of usherin and the pathological mechanisms caused by small pathogenic in-frame variants, like p.Pro3272Leu, molecular dynamics simulations of native and mutant protein–protein and protein–ligand complexes were performed that predicted a destabilization of the protein with a decrease in the free energy change. Conclusions: Our results suggest that our approach is effective for the genetic diagnosis of USH. Based on the heterozygous frequency, targeted screening of this variant in the general population and in families at risk or with familial USH can be suggested. This can lead to more accurate molecular diagnosis, better genetic counseling, and improved molecular epidemiology data that are critical for future intervention plans. Trial registration: We did not perform any health-related interventions for the participants. [ABSTRACT FROM AUTHOR]

Odontodysplasia is an uncommon dental developmental disorder associated with enamel, dentin, pulp abnormalities, and overall tooth morphology. The affected tooth is grossly abnormal in size and contour and is commonly associated with swelling of the affected area and failure of eruption. Histologically, the enamel and dentin are hypoplastic and hypomineralized. Odontodyplasia occurs most commonly in response to direct trauma to the developing tooth bud (enamel organ and dental follicle). Data on the prevalence and features of non-traumatic odontodysplasia are lacking. Medical records of dogs diagnosed with odontodysplasia were reviewed at the William R. Pritchard Veterinary Medical Teaching Hospital (VMTH), University of California, Davis, for 10 years (from 2013 to 2023). Dogs with a known history of facial trauma, persistent deciduous tooth or teeth over the region of odontodysplastic tooth or teeth, and endodontic disease of the persistent deciduous tooth or teeth were excluded from the study. Twenty-eight dogs were included in this retrospective study, representing an incidence of 1.4 per 100 dogs presenting over 10 years. Regional odontodysplasia (RO) was identified in twenty-two dogs, and generalized odontodysplasia (GO) was found in six dogs. Both comprehensive oral examination and diagnostic imaging were essential in diagnosing and assessing the presence of odontodysplasia. Awake oral examination failed to identify odontodysplasia in almost 70% of the RO cases. Secondary diseases or lesions in odontodysplastic teeth, such as periodontal disease, endodontal disease, and perio-endo lesions, were commonly seen and were particularly more frequently identified in strategic teeth (canine and carnassial teeth) than non-strategic ones. Similarities, such as female predilection, maxilla more commonly affected, and clinical signs, were observed between RO in dogs and those reported in people. The exact etiology of non-traumatic odontodysplasia remains elusive, and the condition may be of multifactorial causality. [ABSTRACT FROM AUTHOR]

Introduction: Ectopic foreign bodies in the maxillary sinus occur rarely. Ectopic tooth eruption rarely occurs in the orbit, nasal cavity, maxillary sinus, and elsewhere. Ectopic eruption of teeth in the maxillary sinus is most commonly associated with wisdom teeth and is rarely associated with supernumerary teeth. This rare phenomenon may be accompanied by chronic recurrent sinusitis with headaches and facial pain. However, fibro-osseous lesions in the paranasal sinuses are discovered incidentally on X-ray images and are often asymptomatic. Osteoma is the most common fibro-osseous lesion that develops in the paranasal and nasal sinuses. Osteomas rarely cause serious symptoms such as orbital lesions and intracranial invasion. Case Presentation: We report a rare case of exostosis containing supernumerary teeth within the maxillary sinus. A characteristic pedicled bone lesion with a clear border on computed tomography was the undefined orthopantomogram radiopacity in the maxillary sinus, and the lesion contained supernumerary teeth. As the patient had chronic nasal congestion, the tumor was surgically removed. Pathologically, the surgical specimen revealed an osteoma. The patient's symptoms of chronic sinusitis disappeared. Because the patient had no history of midface trauma or surgery, the supernumerary teeth were speculated to have migrated during a reactive osteogenic process caused by chronic sinusitis. Conclusions: A foreign body in the maxillary sinus can be easily diagnosed by computed tomography. Surgical removal is recommended if the foreign body is symptomatic or occupies more than half of the maxillary sinus. This can help resolve chronic sinusitis symptoms and prevent serious complications in the future. [ABSTRACT FROM AUTHOR]

Cleidocranial dysplasia (CCD) is an uncommon hereditary condition characterized by a range of skeletal and dental irregularities, primarily caused by mutations in the RUNX2 gene. This case report details a 19-year-old female patient who visited the Department of Oral and Maxillofacial Surgery with complaints of multiple supernumerary teeth and retained deciduous teeth. The patient exhibited several hallmark features of CCD, including frontal bossing, an underdeveloped maxilla, a concave head shape, a flattened malar region, short stature with a bell-shaped chest, and sloping shoulders. The clinical presentation and treatment plan, which involved a phased approach combining surgical and orthodontic procedures, are discussed. Virtual surgical planning played a critical role in Surgically Assisted Rapid Palatal Expansion (SARPE). The positive outcome of this case emphasizes the importance of a multidisciplinary strategy in treating CCD and suggests the need for further exploration into standardized treatment protocols for this rare disorder.

Background: Multiple supernumerary teeth, combined with numerous impacted teeth, can lead to various malocclusions, posing significant treatment challenges. While certain genes associated with syndromic cases of multiple supernumerary and impacted teeth have been identified, the etiologies of non-syndromic cases still largely remain elusive. Case presentation: Here, we report a treatment of a 12-year-old boy who presented with 10 supernumerary teeth and 6 impacted teeth, accompanied by a genetic analysis to explore the underlying etiology. During the treatment, fifteen teeth were extracted, and various skilled techniques, including the closed-eruption technique and the application of by-pass arches, were utilized. Post-treatment, traction was successful for all the impacted teeth, without any tooth mobility or reduction in gingival height. Space closure, well-aligned teeth, and excellent functional occlusion were achieved. Furthermore, comprehensive genetic analysis was conducted through whole-exome sequencing on the patient and his parents, which revealed a potential link between the patient's numerous supernumerary teeth and abnormal mineralization. Notably, the p.Ser496Pro variant in the TCF7L2 gene was identified as a potential candidate variant in this patient. Conclusions: Overall, our findings not only report the treatment of a rare case involving multiple supernumerary and impacted teeth but also offer valuable insights into the molecular basis of supernumerary teeth.

Background: Craniosynostosis (CS), premature fusion of one or more cranial sutures, leads to abnormal skull development, impacting both facial esthetics and oral function. This study aimed to evaluate the specific orofacial and oral health characteristics, including masticatory performance, in Thai patients with CS. Methods: A comparative study was conducted with Thai CS patients aged 6–17 years and a control group of healthy individuals with similar age distribution. Assessments included craniofacial morphology, oral health status, and masticatory performance. Intergroup comparisons utilized appropriate statistical tests. Results: The study included 24 CS patients with a mean age of 10.11 ± 2.98 years and 30 controls. CS patients exhibited a significantly higher prevalence of various oral conditions compared to controls: cleft palate (20.8%), anterior open bite (41.7%), anterior crossbite (54.2%), posterior crossbite (50%), combined anterior–posterior crossbite (45.8%), dental crowding in both maxilla and mandible (50% and 45.8% respectively), congenitally missing teeth (50%), supernumerary teeth (12.5%), and eruption failure (54.2%). Furthermore, CS patients exhibited significantly higher caries prevalence and susceptibility, alongside poorer oral hygiene, compared to controls. Regarding jaw relationships, CS patients exhibited a significantly higher proportion of Angle's Class III malocclusion (50%) compared to the control group, where Class I malocclusion was predominant (50%). Masticatory performance, assessed using the two-color gum mixing ability test, showed significantly higher hue variance in CS patients (0.12 ± 0.07) compared to the control group, indicating reduced chewing performance. Conclusion: This study underscores the significant orofacial and oral health challenges faced by children with CS, including a high prevalence of malocclusions, dental anomalies, elevated caries experience, and compromised masticatory function. These findings emphasize the importance of tailored interventions and comprehensive oral healthcare strategies to address the unique needs of this population and improve their overall quality of life.

Objectifs: This 7-years follow-up case report describes two diversified strategies for the management of bilateral mandibular permanent premolars associated with periapical lesion and unerupted supernumerary teeth. Case Report: A non-syndromic 9 years-old Asian female patient presented pain and swelling of the 35 in anatomical contiguity with an immature and unerupted supernumerary tooth. Clinical examination revealed an intraoral vestibular sinus tract related to the necrotic 35. Periapical radiography and CBCT showed that the 35 had an immature apex associated with a periapical lesion, and a supernumerary tooth in a lingual direction. Endodontic treatment of the 35 was performed by creating an apical plug with ProRoot MTA, while the supernumerary tooth was monitored radiographically with no intervention. Four years later, the 45 developed the same clinical condition of the left arch. Radiographic examination revealed a periapical lesion with massive periapical bone resorption, and a supernumerary tooth in normal alignment. The second premolar was herein extracted to allow for eruption of the supernumerary tooth. Outcomes: 3-years follow-up revealed continued root maturation and its spontaneous eruption in the dental arch. Proper healing of both mandibular lesions was monitored after 10 months, 3-years and 7-years revealing no recurrence on both sides. [ABSTRACT FROM AUTHOR]
