Porcelain laminate veneers (PLV) offer a conservative aesthetic solution for interdental space closure. However, space is typically not distributed symmetrically, and the mesiodistal width of the restored teeth may increase unless multiple teeth are prepared for conventional PLV to maintain appropriate individual tooth proportion. Ceramic fragments can be suggested to close the space without modifying tooth size and dental proportion. This article presents two cases where interdental gaps were closed using lingually placed porcelain laminate (LPPL). All stages of the restorative procedures, including treatment planning, temporization, tooth preparation, and cementation of these delicate restorations, are detailed. Based on the results of these clinical reports, we regard the use of LPPL as a successful treatment option in selected cases, as evidenced by 2- and 6-year follow-ups. The Modified United State Public Health Criteria is reported. [ABSTRACT FROM AUTHOR]

The upper lip frenum is a crease-shaped mucous membrane located in the oral region in the sagittal plane, often can present changes in its structure and shape, causing an interincisive diastema, problems in hygiene, speech and gingival recession, favoring vicious habits, and can generate compromised lip movement. This study aims to report a clinical case of upper lip frenectomy in a child patient highlighting the diagnosis, surgical treatment and prognosis. The clinical case refers to a seven-year-old female patient who, after the eruption of the upper central and lateral incisors, clinically presented the frenum with low insertion, causing interincisal diastema. After clinical and radiographic examination, upper labial frenectomy was planned, using the modified Archer technique. Therefore, we conclude that this technique is less traumatic to the infant patient, due to its simplicity and speed, with a positive result and good prognosis. [ABSTRACT FROM AUTHOR]

Introduction: Orthodontic discrepancies are a common finding in patients with supernumerary teeth (ST). The presence of a ST can cause a number of orthodontic discrepancies, including delayed eruption or retention of adjacent teeth, crowding, spacing, and abnormal root formation. The aim of the present study was to assess the effect of extraction of an anterior supernumerary tooth on the underlying orthodontic discrepancies without additional treatment for a 6-month period. Methods: This was a prospective, longitudinal, observational, study. It included 40 participants with orthodontic malocclusions due to maxillary anterior supernumeraries. We examined the changes in the crowding and excessive space in the anterior and posterior segments on cast models. Results: In the group that presented with crowding, a statistically significant decrease of 0.95 ± 0.17 mm (P < 0.001) was found between T0 and T1. Of the participants, three exhibited full self-correction. The excessive space at T0 (3.06 mm) decreased by 1.78 ± 0.19 mm to T1 (1.28 mm) in the anterior segment. Seven participants showed full self-correction of the diastemas after the 6-month observation period. Conclusion: The results imply that orthodontic treatment can be postponed for at least 6 months after the extraction of the supernumerary tooth as potential self-correction can be expected. This natural alleviation of the malocclusions may make the orthodontic treatment simpler, shorten the treatment time and decrease overall appliance wear time. [ABSTRACT FROM AUTHOR]

Bone grafts are commonly used to treat periodontal bone abnormalities. Studies indicate that using graft materials in directed tissue regeneration is effective. However, treating deep and extensive bony defects can result in a large area that lacks blood flow from the periodontal ligament or alveolar bone. This poses a risk of wound failure when an incision of the defect-associated papilla is performed. (17) Bianchi and Basetti developed a new surgical technique called the "Whale's Tail" to address this issue. This approach can effectively regenerate broad intrabony defects in the esthetic zone while preserving interdental tissues over grafting material. The proposed procedure entails the elevation of a sizeable flap from the buccal to the palatal side, thereby providing an unobstructed view and access to the intrabony defect in question.

Introduction: Malocclusion profoundly impacts a child’s emotional well-being and affects an individual’s quality of life. Early identification improves the chances of organising preventive and interceptive treatment to limit the intensity of developmental aberrations. The data for malocclusion among children of Visakhapatnam is lacking. Aim: To study and evaluate the prevalence of malocclusion and ascertain gender dimorphism among six- and nine-year-old school-going children of Visakhapatnam Materials and Methods: A cross-sectional, double-stage sample study was conducted among 616 school-going children of Visakhapatnam, Andhra Pradesh, India, by a single calibrated examiner using a modified Index for Preventive and Interceptive Orthodontic Needs (IPION). IBM Statistical Package for the Social Sciences (SPSS), version 25.0, was used to analyse data and Pearson’s chi-square test to elicit gender differences in the prevalence of malocclusion traits. Results: Prevalence among six-year-old children: interproximal caries-38.4%, premature tooth loss-10.1%, supernumerary teeth-0.3%, upper molar rotation-0.3%, lower molar tipping-2%, anterior crossbite-2.7%, posterior crossbite-0.7%, overjet more than 3 mm-5.1%, overbite more than 2/3rd-8.4%, open bite-2%, incompetent lips-13.8%. Prevalence among nine-year-old children: interproximal caries-49.5%, premature tooth loss-8.8%, active frenum-2.8%, supernumerary teeth-0.6%, diastema-3.4%, upper molar rotation-2.2%, lower molar tipping-5%, impended eruption of first permanent molar-1.3%, overjet more than 3 mm11%, overbite more than 2/3rd-12.5%, open bite-2.2%, anterior crossbite-8.2%, posterior crossbite tendency-3.1%, Class I-75.6%, Class II-18.8%, Class III (functional shift)-0.6%, Class III (no functional shift)-3.76%, incompetent lips-16.3%. Conclusion: Children from both cohorts demonstrated malocclusion traits. The nine-year-old group had greater prevalence for all components examined except premature tooth loss. No statistically significant gender dimorphism was found in both cohorts.

The process of removing a frenulum is one of the specialties of cosmetic dentistry. Inside the mouth there are two tissues known as the frenulum. This tissue includes both the teeth and the gums. It is usually divided into the frenulum of the tongue, which is the space between the level of the mouth and the tongue. Its function is to prevent the tongue from moving freely, which is why doctors recommend removing it. While the other section is known as lip frenulum, which is when the lip is too high, which forms an obstacle in front of the front teeth and pushes them away from each other. Also, this problem requires frenulectomy surgery. In this case report, we present a case of surgery performed to remove the upper labial frenulum in a patient in his forties. The previous patient visited the clinics of the International University for Science and Technology complaining of a massive diastema in his upper jaw. Therefore, we performed surgical resection of the superior labial frenum. We administered local anesthesia to the patient in order to perform the surgical procedure. We monitored the patient's condition for two and a half weeks in order to ensure his recovery and the success of the surgery.

The article discusses the treatment of mesiodens in different stages of dentition. Topics include the clinical presentation and radiographic features of mesiodens; treatment approaches, including extraction methods using specialized forceps to prevent damage to adjacent permanent tooth germs; and post-extraction management, including follow-up care and the use of removable orthodontic appliances like Hawley's plates for diastema closure and alignment in older children.

Purpose: The purpose of this multicenter study was to evaluate the survival and quality outcome of direct composite buildups in the anterior dentition based on representative sample sizes. Materials and Methods: At three university clinics in Germany, the survival and quality outcome of n = 667 direct composite buildups performed between 2001 and 2012 was evaluated in n = 198 participants. Survival outcomes were categorized as failure (F), survival (SR), or successful (S). Restorations still in place and without failure prior to follow-up (n = 567) were rated using modified USPHS/FDI criteria to obtain the quality outcome. Detailed failure analysis was done by means of Cox regression models. Results: The restricted mean for overall survival was 15.5 years. N = 576 restorations were classified as successful (S), n = 81 survived with repair (SR) and n = 8 failed (F). Two restorations were removed due to iatrogenic interventions. Overall survival rates after 2, 10, and 15 years were 98.8% (CI: 97.6 and 99.4), 91.7% (CI: 89.0 and 93.8), and 77.6% (CI: 72.2 and 82.2), respectively. Functional survival rates were 100.0%, 98.9% (CI: 97.5 and 99.5), and 98.5% (CI: 96.7 and 99.3), respectively. Clinical quality was rated as excellent or good for most restorations. The dominant failure mode was chipping; however, regression analysis did not detect any influence of the evaluated parameters "enlargement range," "position in the jaw," or "tooth type" on failure. Conclusion: This multicenter study represents the first of its type including clinical survival and quality data on 576 direct anterior composite buildups over a restricted mean follow-up of 15.5 years in a relatively large group of participants. In particular, functional survival was outstanding due to the clinical reliability of this treatment option, while simultaneously providing flexibility, reparability, and minimal invasiveness.

Patients with missing anterior teeth along with diastema or generalised spacing present as a peculiar clinical situation. For patients seeking fixed modality of treatment and who wish to retain their existing diastema or spacing, rehabilitation with a conventional fixed dental prosthesis, resin bonded fixed dental prosthesis would lead to unesthetic results leaving them with limited treatment options. Loop connector fixed dental prosthesis is a simple solution for such patients with excellent treatment outcomes. [ABSTRACT FROM AUTHOR]

Background: Mixed dentition determines an important period of occlusion development in childhood. Objective: This study aimed to evaluate the aesthetic impact of the midline diastema cut‐off point in mixed dentition. Design: A cross‐sectional study was performed with 257 children aged 8‐10 years in late mixed dentition, with midline diastema of 1‐5 mm and normal maxillary overjet. Orthodontic Aesthetic Subjective Impact Score determined the aesthetic impact of the midline diastema. Four quartiles of diastema measurements and impact scores were considered as cut‐off points. Receiver Operating Characteristic curves were constructed, and the distances representing the distances to the ideal point were calculated. The Yuden index determined the efficiency of measuring the diastema to assess the aesthetic impact. The Kruskal‐Wallis test compared the groups of participants classified according to the diastema cut‐off by the sample quartile regarding the impact score. The analyses were performed with a significance level of 5%. Results: There was no significant difference between the four groups of measurement quartiles of the diastema regarding the aesthetic impact (P >.05). Conclusions: The perception of dental aesthetics in mixed dentition children was not affected by the midline diastema, regardless of the cut‐off point. [ABSTRACT FROM AUTHOR]

Midline diastema has been a popular aesthetic problem for children. Several treatment options are available, however, the use of elastic bands without other appliances for closing the diastema still remains a pressing issue in Vietnam, which could be done by the patient’s parents either themselves or under the dental practitioners’ suggestion. Objective: To report a specific case about the extensive extrusion regarding upper central incisors in a pediatric patient due to misusing the elastic band, in which management was complex due to an unfavorable situation for splinting. Case Report: Single rubber band usage for orthodontic movement in closing diastema has been an unresolved disaster in Vietnam, leading to the need for early diagnosis and immediate intervention when facing the complications. Conclusion: Significant information dissemination is paramount for long-term improvement in the oral health of pediatric patients in Vietnam and around the world. [ABSTRACT FROM AUTHOR]

Introduction: Supernumerary teeth are extra teeth to normal dental formula. They are developmental anomalies which may have multiple etiologies. They may or may not erupt in the oral cavity and are mostly diagnosed incidentally. Case Reports: This is the presentation of case series of seven such different types of supernumerary teeth. Among these cases, the treatment of two cases has been shown along with their photographs. Conclusion: Their most common form is mesiodens which are commonly found in the maxillary anterior region creating unesthetic appearance for which patient seeks treatment. If not diagnosed and managed on time they can create complications such as malalignment, diastema, crowding, noneruption, delayed, or altered eruption of permanent tooth. This case series is an attempt to showcase the deleterious effect of supernumerary teeth and their varied clinical presentation along with their plan of management.

Abstract Background Progressive familial intrahepatic cholestasis is a heterogeneous group of disorders, leading to intrahepatic cholestasis, with the possibility of chronic liver failure and biliary cirrhosis. Oligodontia is either the manifestation of a specific syndrome or is non-syndromic. To the best of our knowledge, this is the first case report of type 3 progressive familial intrahepatic cholestasis and concurrent oligodontia, craniosynostosis, dens in dente, taurodontism, and delayed permanent dentition in the medical and dental literature. Case presentation We present the dental and medical histories and comprehensive dental management of a girl with type 3 progressive familial intrahepatic cholestasis and several dental anomalies, who was referred to a dental clinic due to severe dental caries and pain. Conclusion Our findings suggest that PFIC with manifestations as oligodontia, craniosynostosis, dens in dente, taurodontism, and delayed permanent dentition, might indicate an unknown syndrome; otherwise, the craniofacial anomalies are the manifestations of an independent disease coinciding with PFIC. Moreover, our case is a good example of the importance of timely medical and dental care in confining further health-related complications. The patient was able to ingest without any pain or discomfort after receiving proper dental management.

Diastema, interdental alanda boşluklar ve kontakt noktası yokluğu ile karakterize dişşel bir anomalidir. Bu olgu sunumunda maksiller anterior bölgede bulunan diastemanın, direkt kompozit rezin ile rehabilite edilmesi sunulmaktadır. 25 yaşında kadın hasta, maksiller ön dişleri arasındaki diastema sebebiyle kliniğimize başvurdu. İlk seansta hastadan başlangıç fotoğrafları alınıp, renk seçimi yapıldı. Ardından ölçü alınıp, dijital wax-up ve silikon indeks hazırlandı. İkinci seansta ilgili dişler %37’lik ortofosforik asit ile pürüzlendirilip, 10 saniye süreyle yıkandı ve kurutuldu. Adeziv sistem uygulanıp, LED ışık cihazı kullanılarak polimerize edildi. Kompozit rezin ile dişler arasındaki diastema kapatılıp, polimerize edildi. Dişlere uygun form verilerek polisaj işlemi tamamlandı. Kısa sürede tamamlanabilen ve hastanın estetik beklentilerini karşılayan, maliyeti görece daha düşük direkt restoratif tedaviler; diastemaların kapatılması için başarılı bir tedavi alternatifidir.

Diastema, dişler arasında görülen açıklıktır veya çene ve diş boyutları arasındaki farklılıklardan kaynaklanan meziodistal boşluklardır. Bu vakada ön dişlerin diastemalarının direkt kompozit rezin restorasyonlar ile diş yüzeylerinde herhangi bir ön hazırlık gerektirmeksizin tek seansta estetik tedavisi anlatılmıştır.Öncelikle kompozit rezinin doğal dişlere göre uygun renk tonu seçimi yapıldı. Diş yüzeyleri %37’lik fosforik asit ile pürüzlendirildi ve üreticinin talimatlarına göre iki aşamalı self etch adeziv uygulandı. Daha sonra şeffaf bandlar ile kompozit rezin şekillendirilerek diastemalar kapatıldı. Son olarak, ince grenli elmas frezler ve kompozit polisaj diskleri kullanılarak bitirme ve polisaj işlemleri gerçekleştirildi. Hastanın estetik beklentileri tek seansta ortadan kalktı. Estetik şikayetleri olan hastalarda yeterli oral hijyen motivasyonu sağlandığında direkt kompozit restorasyonun başarılı bir tedavi seçeneği olduğu gözlemlenmiştir.

Giriş: Üst çene ön bölgede yer alan dişler arasında diastema görülmesi en sık karşılaşılan estetik problemlerden biridir. Orta hatta diastema görülmesinin en önemli nedenleri, dişlerin form ve şekillerindeki farklılıklar, diş eksiklikleri, diş arklarının boyutu ile dişlerin boyutları arasındaki uyumsuzluklar, parmak emme gibi alışkanlıklardır. Olgu Sunumu: Kliniğimize üst çene ön bölgesinde yer alan diastemaları için başvuran 30 yaşındaki erkek hastaya yapılan klinik ve radyolojik muayene sonucunda, 13-11-21-23 numaralı dişlerin arasında diastemaların olduğu tespit edildi ve rezin kompozit ile diastemaların kapatılmasına karar verildi. Tedavisinin tamamlanmasından sonra, hasta takibe alındı. Klinik Sonuç: Orta hatta görülen diastemaların direkt teknik ile rezin kompozit kullanılarak kapatılmasının estetik problemlerin giderilmesinde klinik olarak avantaj sunduğu belirlenmiştir.

Diastema dişlerin form ve şekillerindeki farklılıklardan, diş eksikliklerinden ya da diş arklarının boyutu ile dişlerin boyutları arasındaki uyumsuzluklardan kaynaklanmakta ve estetik sorunlara neden olmaktadır. Kliniğimize 40 yaşında kadın hasta, eski restorasyonlarının formundan ve dişleri arasındaki boşluk şikayetleri nedeni ile başvuran hastanın 13, 12, 11, 21, 22, 23 numaralı dişleri arasında diastema varlığı tespit edildi ve direkt kompozit rezin uygulaması ile ilgili dişlerin restore edilmesine karar verildi. Wax-up model üzerinden silikon indeks hazırlandı. İlgili dişlerin mine yüzeylerinde 30 saniye %37’lik fosforik asit uygulandı, yıkandı ve kurutulduktan sonra mine yüzeylerine adeziv sistem (Tetric N-Bond, Ivoclar Vivadent, Schaan, Liechtenstein) uygulandı. Silikon indeks yardımıyla nano-seramik kompozit rezin restoratif materyal (Specktra ST-HV,Dentsply Sirona, Amerika Birleşik Devletleri) ile restorasyon tamamlandı. Restorasyon tamamlandıktan sonra bitirme ve parlatma işlemi kalın grenliden ince grenliye doğru sıra ile parlatma diskleri (Optidisc, Kerr, Amerika Birleşik Devletleri) kullanılarak yapıldı.

La presencia de los diastemas es una de las quejas estéticas más comunes entre los pacientes. La utilización de resinas compuestas es una buena opción estética y funcional para realizar restauraciones e implementar técnicas restauradoras de forma mínimamente invasiva. La técnica de estratificación con resinas se introdujo en 1980 dando muy buenos resultados en la selección de color, pero siendo el procedimiento más complejo y requiriendo grandes habilidades técnicas además de un aumento de tiempo clínico. Los materiales de composite y técnicas restauradoras que ayudan al uso simplificado de protocolos clínicos son muy procurados por los odontólogos para reducir el tiempo de trabajo en el sillón y minimizar la sensibilidad post operatoria. Es por estos motivos, además de simplificar la toma de color, que Tokuyama Dental desarrolló la resina Omnichroma que dice tener la habilidad de copiar el color del sustrato del diente remanente poco después de la fotopolimerización conocido como “Efecto Camaleón” utilizando un solo tono. El objetivo de este artículo es el de describir detalladamente mediante un reporte de caso clínico el cierre de diastemas con la resina universal Omnichroma de Tokuyama Dental.

OBJECTIVE: To find the different etiological factors underlying a midline diastema which will help in effective orthodontic correction by enabling the practitioner to adopt the most appropriate mechanics. METHODS: This descriptive cross-sectional study was conducted at the Department of Orthodontics, Nishtar Institute of Dentistry, Multan, from 01-08-2020 to 01-02-2021. A sample of 165 patients was analyzed according to age, gender, presenting various occlusal traits, and relevant diastema findings to assess the underlying etiology of the maxillary midline diastema. Cases with a midline diastema of >0.5 mm were documented with examination including clinical intra-oral examination and orthopantomograms and upper occlusal radiographs. Examinations were done by the same observer to reduce human error and were cross-checked by a superior to minimize the possibility of error. The data was analyzed using SPSS version 20.0. RESULTS: Dental anomalies (n=113, 68.6%) was the most frequent cause of maxillary midline diastema. Dental anomalies were observed in both females (n=77/112; 68.8%) and males (n=36/53; 67.9%). Common dental anomalies included tooth/arch size discrepancies (n=58, 51.3%), abnormal occlusal patterns (n=37; 32.7%) and missing teeth (n=18 15.9%). Other contributing factors for maxillary midline diastema observed were abnormal maxillary arch structure (n=30; 18%), physical impediments (n=18; 11%), muscular imbalances (n=3; 1.8%) and pernicious habits (n=1; 0.6%). Common causes of physical impediments were fleshy labial frenum 10/18; 55.6%) and supernumerary tooth (n=8/18; 44.4%). CONCLUSION: Maxillary midline diastema was common in both genders and was associated with multiple etiologies of which dental anomalies, abnormal maxillary arch structure and physical impediments were highly prevalent.

Objectives: The aim of this retrospective evaluation was to assess the short‐term outcome of two monoshade universal resin composites with high chameleon effect in anterior direct veneer and diastema closure restorations, and to investigate the possible reasons for failure. Material and Methods: Patients subjected to veneer and diastema closure restorations with two monoshade universal resin composites (Essentia Universal Shade; EU, GC Corp., and Omnichroma; OC, Tokuyama) operated between January 2018 and March 2019 were selected for the present retrospective evaluation. A total of 159 composite restorations (78 veneers and 81 diastema closure restorations) performed by a single operator in 44 patients (mean age: 33.6) were included in the study. Two blinded and calibrated examiners performed 1‐ and 2‐year assessments of the restorations with respect to FDI criteria, using medical/clinical history and dental photography records. Data were analyzed using Pearson Chi‐square with Continuity Correction, Fisher's Exact tests, and Cox regression (a < 0.05). Results: The cumulative overall survival rates of EU and OC restorations were 94.6% (97.3% for the first year) and 88.6% (95.3% for the first year), respectively, with no significant difference from each other (p = 0.316). The cumulative overall survival rates of direct veneer and diastema closure restoration types were 90.2% (95.1% for the first year) and 92.4% (97.4% for the first year), respectively, with no significant difference (p = 0.559). The reasons for failure were evaluated as fracture of the restoration, failure in esthetic anatomical form, and color mismatch. All the failed direct veneer restorations were due to fractures (FDI score of 5.4), whereas 5 of 6 failed diastema closure restorations were due to color mismatch (FDI score of 3.4). Regarding the composite materials, there were no significant differences between the success rates of the restoration types (p = 0.442 for EU, p = 1.000 for OC). With respect to the restoration types, there were also no significant differences between the success rates of the resin‐based composites (p = 1.000 for direct veneer restorations and p = 0.228 for the diastema closure restorations). In addition, no significant difference was observed between male and female patients regarding the acceptable and unacceptable scores (p = 1.000). Conclusions: The 2‐year clinical performance of the two monoshade universal composites in anterior veneer and diastema closure restorations were both considered successful and similar. Despite the lack of shade selection, both monoshade universal composites presented a successful color match. However, the diastema closure restorations might be more prone to color mismatch compared to the veneers over time, while veneer restorations presented more fractures than the diastema closure restorations. Clinical Significance: Monoshade universal composites presented successful short‐term clinical outcomes regarding both function and esthetics in anterior direct veneer and diastema closure restorations.

This report describes the combination of two surgical fracture repair techniques and the postoperative management of a mandibular diastemal fracture in a two-year-old mare. The mare was referred to a veterinary hospital with a laceration over the body of the right mandible. Radiographic assessment revealed two mesial fracture lines involving the second premolar tooth and a ventrally displaced bone fragment. The mare was treated under general anesthesia and the fracture was corrected using open reduction and plate fixation. A 3.5 mm narrow 15-hole locking compression plate with seven locking screws were used in a bridge form. Cerclage wire was also used to anchor the incisor teeth to the second and third premolar teeth. The cerclage wire and incisor teeth were covered with polymethylmethacrylate to prevent implant failure and avoid injury to the oral mucosa. Implants were removed 55 days after surgery and the mare was discharged from hospital five days later. The mare returned for cerclage wire removal after 90 days and was allowed to resume exercise thereafter.

The use of digital smile designing simplifies the restoration of esthetics. In this article, a case of diastema and incisal notching in anterior teeth was rehabilitated with porcelain laminate veneers using combination of digital and analog workflow.

Dişler ark üzerinde yan yana kontaktadır. Diastema dişlerin arasındaki boşluklardır ve farklı sebeplerle oluşabilir. Dişlerin çene yapısına göre daha küçük olması, genetik, anormal labial frenulum ataşmanı, yanlış alışkanlıklar, diş eksikliği gibi durumlar diastemaya neden olabilir. Hastaları kliniğe getiren ana sebep duydukları estetik kaygılardır. Diastema kapatılmasında ortodontik, protetik ve restoratif yaklaşımlar uygulanabilir. Preparasyonsuz direkt restoratif tedavi dişler arası boşluklarda dişlerde madde kaybı olmadan uygulanan restoratif tedavi seçeneğidir. Hastaya tedavi seçenekleri, riskleri ve faydaları anlatıldıktan sonra hastanın üst 13-23 arasındaki interdental boşlukları direkt kompozit restorasyon ile kapatılmıştır. Direkt kompozit restorasyon ile tedavi genellikle tek seansta yapılır, laboratuar işlemleri gerekmez ve daha ekonomiktir.

ABSTRACT Objective: The aim of the present literature review was to compile data on the frequency of morphological and attachment types of the upper and lower labial frenum in different populations and investigate the association between the attachment level of the upper labial frenum and the occurrence of diastemas. Methods: Searches were conducted between May and June 2021 in the Medline (via Ovid), Google Scholar and CAPES databases. Thirty-eight studies that evaluated frenum morphology, frenum morphology and attachment or frenum morphology, attachment and the occurrence of diastemas were selected for the extraction of data. Results: Based on the data compiled in this review, the most common morphological and attachment types were labial frenum normale and mucosal attachment. The papillary and papilla penetrating types of attachment were more associated with the occurrence of diastemas. Conclusion: Longitudinal studies are needed to investigate this correlation in children and adults.

Background: Progressive familial intrahepatic cholestasis is a heterogeneous group of disorders, leading to intrahepatic cholestasis, with the possibility of chronic liver failure and biliary cirrhosis. Oligodontia is either the manifestation of a specific syndrome or is non-syndromic. To the best of our knowledge, this is the first case report of type 3 progressive familial intrahepatic cholestasis and concurrent oligodontia, craniosynostosis, dens in dente, taurodontism, and delayed permanent dentition in the medical and dental literature. Case presentation: We present the dental and medical histories and comprehensive dental management of a girl with type 3 progressive familial intrahepatic cholestasis and several dental anomalies, who was referred to a dental clinic due to severe dental caries and pain. Conclusion: Our findings suggest that PFIC with manifestations as oligodontia, craniosynostosis, dens in dente, taurodontism, and delayed permanent dentition, might indicate an unknown syndrome; otherwise, the craniofacial anomalies are the manifestations of an independent disease coinciding with PFIC. Moreover, our case is a good example of the importance of timely medical and dental care in confining further health-related complications. The patient was able to ingest without any pain or discomfort after receiving proper dental management. [ABSTRACT FROM AUTHOR]

Maxillary midline diastema is a frequently occurring malocclusion found to be a common aesthetic complaint of patients. It occurs due to of multifactorial etiology such as labial frenum, microdontia, and oral habits such as thumb sucking, Tongue thrusting, or Dental malformations. Proper technique and materials for successful treatment are grounded on time and the patient's physical, psychological, and economical conditions. The use of Direct composite resin restoration in diastema closure permits the dentist and patients to gain complete control of the above-mentioned and recreation of an aesthetic natural smile. The case report describes a case of midline diastema closure using direct composite resin restoration. The patient was recalled for follow-up for 1 year. No discoloration, sensitivity, line of demarcation, or fracture lines were seen. Therefore, midline diastema closure using direct composite resin restoration is considered highly aesthetic, and durable and could fulfill the aesthetic need of the patient in the present case.

Ceramics have greatly evolved since they came into the eye of the dental community. Currently, there is a demand for a highly aesthetic as well as strong restoration and high translucent zirconia fits that criteria pretty well. This has significantly increased the applicability of zirconia as a restorative material in aesthetically demanding cases. Veneers have an innate disadvantage of lack of strength, decreased fracture resistance and chipping. Using these highly translucent zirconia veneers will help overcome these disadvantages. Therefore, the objective of the case series was to test the effectiveness of adhesively bonded highly translucent zirconia veneers using resin cement. This type of veneers provides satisfactory aesthetic outcomes and decreases the risk of fracturing during the trial and clinical use. However, further studies with long-term follow-ups are needed.

IntroductionPituitary pars intermedia dysfunction (PPID) and dental disorders are of major concern in horses older than 15 years. Although PPID in geriatric horses and dental disorders in all age groups are well described, a connection between this endocrine disease and pathological changes in equine dental structures has not yet been investigated. In humans, periodontitis is considered to be a complication of systemic diseases like diabetes mellitus type 2, obesity and various conditions leading to an impaired immune response. In PPID, cross links to insulin and immune dysregulations are proven. The aim of this study was to compare histological findings of the gingiva and the sub gingival periodontal ligament of PPID affected horses with control horses.MethodsIn a case-control morphometric descriptive study, 145 dental locations of 10 PPID affected horses (27.3 ± 2.06 years) were compared with 147 dental locations of 10 controls (21.4 ± 4.12 years). Histological parameters were leukocyte infiltration, keratinization of gingival epithelium, blood vessel supply of the periodontium and structure of cementum.ResultsThe distribution and localization of gingival leukocyte infiltrations (LI) in PPID affected horses was more often multifocal to coalescing (p = 0.002) and reached into deeper parts of the periodontium, sometimes down to the sub gingival periodontal ligament (PDL). Aged animals of both groups showed higher prevalence (PPID: OR 1.66; controls: OR 1.15) for severe leukocyte infiltration in the PDL. PPID was not significantly associated with increased LI. The cementum bordering the soft tissue in interdental locations showed four times more irregularities in PPID affected horses than in controls which predisposes for interdental food impaction and periodontal diseases.DiscussionIn summary, multifocal to coalescing leukocytes and irregular cementum are seen more often in PPID than in controls - however our findings mainly reflect an association of older age with periodontal disease.

Introduction: The midline diastema is space or gap between the maxillary central incisors. it is a common esthetic complaint of patients. Aim: The aim of this article is to know the knowledge and awareness of dental students in the management of Midline diastema. Materials and Methods: A questionnaire of 16 questions was created and entered in the online survey creator 'Google Forms' and shared among each student of about 100 individually and privately and data were collected subject to statistical analysis using SPSS software. Statistical tests used were descriptive statistics and Chi square tests. P value less than 0.05 was considered statistically significant. p value was found to be 0.261 which statistically insignificant Conclusion: Results of this study suggest that Preclinical dental students were lacking some knowledge in management of Midline diastema, so they need an effective education and awareness campaign to increase their knowledge and awareness on management of Midline diastema.

Objective: To evaluate the effect magnitude of different parameters on smile attractiveness. Materials and methods: A reference and 13 images were produced by manipulating 13 parameters. Image rating was performed with a 4‐point Likert scale from least attractive (1) to most attractive (4). Image raters included laypeople, dental students, dentists, and dental specialists. Friedman and Wilcoxon image were used for estimate of effect size. Parameters were classified into small (0.10‐ < 0.30), medium (0.30‐ < 0.5), or large (≥0.50). Results: A total of 1040 people participated with good consistency (α = 0.861), and moderate reliability (0.64–0.7). The reference image had the highest rank (laypeople:11.79, dental background: 12.55). For effect size; gingival margin level (−0.11, −0.01), teeth width proportion (−0.09, −0.10), inverted smile arch (−0.09, −0.21), commissure line cant (−0.15, −0.17) and low smile (−0.24, −0.23) had small effect size; occlusal plane cant (−0.36, −0.49), midline cant (−0.36, −0.48), and midline shift (−0.37, −0.49) had medium effect size; diastema (−0.55, −0.54) and color (−0.56, −0.56) had large effect size for the laypeople and dental groups. High smile (−0.42, −0.51), incisor edge symmetry (−0.46, −0.54) had medium effect size in laypeople group and large effect size in the dental group. Width to length tooth proportion (−0.26, −0.39) had small effect size in the laypeople group and medium effect size in the dental group. Conclusions: Smile parameters had different effect magnitude on smile attractiveness and were classified into small, medium, or large parameters. Neither laypeople nor professionals have a collective judgment on what constitutes a beautiful smile. Clinical significance: This study investigated the effect magnitudes of 13 smile parameters and presented a small, medium, and large smile parameters classification. It should provide the clinician with an insight into the expected effect each parameter has on the smile. [ABSTRACT FROM AUTHOR]

Introduction: A modified frenal treatment for aberrant frenum is presented in this report to reduce scar tissue formation and maintain the attached gingiva. Description: The case report describes two cases in which a V-shaped incision removed the aberrant frenum and then the flaps of the frenum were sutured at the mid line. Results: The results showed reduced scar tissue in the mid line and the tissue healed with adequate attached gingiva. Take-Away Lessons: The modified frenotomy technique presented here is ideal for a large frenum that could expose the underlying connective tissue that could reduce the scar tissue formation.
