Background: Dental diseases pose a global health problem that significantly affects overall well-being and quality of life. They are frequently neglected in many regions, despite the availability of preventive measures and it remains unclear whether these measures are effectively implemented in practice. Therefore, this study aimed to evaluate dental health practices among primary school children in both rural and urban areas of Rwanda. Methods: A cross-sectional study was conducted on 195 school children including 96 from a rural area and 99 from an urban area. Data were collected through a questionnaire and analyzed using SPSS version 21. To compare practices between the rural and urban groups, Fisher's exact test was utilized, with a significance level set at 0.05. Results: The findings show significant differences in dental health practices between rural and urban areas, revealing that rural children were less likely to visit the dentist regularly (p = 0.026) and had a higher frequency of sugary drink consumption (p = 0.002). Additionally, disparities were found in the materials used for tooth brushing (p < 0.001) and the timing of toothbrush replacement (p = 0.011), indicating that rural children often use inappropriate brushing materials and replace their toothbrushes less frequently. Conclusion: This study highlights significant differences in dental health practices between rural and urban children in Rwanda. Rural children were less likely to visit the dentist, consumed more sugary drinks, and used inappropriate brushing materials with less frequent toothbrush replacement. These findings underscore the need for targeted interventions to improve oral health awareness and practices especially in rural areas. [ABSTRACT FROM AUTHOR]

Background and Objectives: Modernization and population aging have increased the prevalence of systemic diseases, such as diabetes and hypertension, which are often accompanied by various dental diseases. Our aim was to investigate associations between common dental conditions and major systemic diseases in an elderly Korean population. Materials and Methods: Utilizing electronic medical record data from 43,525 elderly patients, we examined the prevalence of systemic diseases (diabetes, hypertension, rheumatoid arthritis, osteoporosis, dementia) and dental conditions (caries, periodontal disease, pulp necrosis, tooth loss). The analysis focused on the correlations between these diseases. Results: Significant associations were found between systemic diseases and an increased prevalence of dental conditions. Patients with systemic diseases, especially those with multiple conditions, had higher incidences of periodontal disease and tooth loss. The correlation was particularly strong in patients with diabetes and rheumatoid arthritis. Interestingly, temporomandibular joint disorder was less frequent in this cohort. Conclusions: The findings highlight the importance of integrated dental care in managing systemic diseases in elderly populations. Enhanced dental monitoring and proactive treatment are essential due to the strong association between systemic diseases and dental conditions. Collaboration between dental and medical professionals is crucial for comprehensive care that improves health outcomes and quality of life for elderly patients. [ABSTRACT FROM AUTHOR]

Dental disease is common in captive-managed macropods, including Bennett's wallabies, and is a significant cause of morbidity and mortality. Dental extractions and debridement of diseased tissue is often necessary for those undergoing treatment for severe dental disease. Regional anesthesia of the dentition is considered standard of care for domestic animals undergoing orofacial surgery, however, it is not routinely performed in macropods due to limited information on dental anatomy and block approaches. Regional block descriptions for the infraorbital, maxillary, inferior alveolar, and mental blocks in domestic dogs and cats were evaluated and adapted for use in Bennett's wallabies based on descriptions of their anatomy and examination of 2 skulls. These approaches were then performed on cadaver heads with iohexol and methylene blue dye, and block placement was assessed on computed tomography scans and by gross dissection. All block approaches described in this study resulted in appropriate placement of regional anesthesia of the dentition in Bennett's wallabies. They can thus be used by clinicians to improve the intra and postoperative pain control of patients and provide a high level of veterinary care. [ABSTRACT FROM AUTHOR]

Objective Materials and Methods Results Conclusion This study investigated risk factors contributed to benign and malignant oral tumors using longitudinal cohort big data.We included individuals aged ≥40 years who participated in the National Health Examination in South Korea between 2003 and 2004. National Health Insurance claims data after 16 years were used to determine the incidence of oral tumors and the related risk factors. Hazard ratios were calculated using the Cox proportional hazard regression.A total of 5,992,671 participants were included. The incidence of oral cancer was significantly higher in men and increased with age, whereas that of benign tumors was unaffected by sex and decreased with age. Periodontal disease was associated with the incidence of oral cancer but not benign tumors. Soft tissue diseases were associated with both benign and malignant tumors. Various systemic diseases influence the development of oral tumors. Light alcohol consumption reduced the incidence of oral tumors, whereas heavy alcohol consumption increased the incidence of malignant tumors only. Smoking increased the incidence of benign but not malignant tumors.Recognized risk factors such as sex, age, comorbidities, and dental diseases were associated with oral tumors. Alcohol consumption and smoking were not significantly associated with malignant tumors. [ABSTRACT FROM AUTHOR]

To determine which types of bone lesion (spicules, lobules, porous bone) in the maxillary sinus indicate sinusitis Subadjacent dental disease is a cause of maxillary sinusitis; if a lesion type indicates sinusitis it should be more common above diseased posterior maxillary teeth than a lesion type that is not indicative of sinusitis. The study sample is a British Mediaeval human skeletal collection. Porous bone lesions (chiefly new bone deposits) in maxillary sinuses are associated with subadjacent dental disease; spicules/lobules of bone in the sinus are not. The results support the idea that porous lesions indicate sinusitis but the spicules/lobules may not. Spicules, lobules and porous lesions within the maxillary sinus should be analysed separately in biocultural studies; it would be prudent to regard only the porous lesions as indicative of sinusitis. Maxillary sinusitis is commonly used as a health indicator in palaeopathology, and spicular deposits are generally the most common type of alterations. By assuming that they are indicative of sinusitis we may have been greatly overestimating the prevalence of bony sinusitis in the past. These conclusions are provisional. Further work on larger, more diverse samples, together with more detailed anatomical studies on lesion location and structure is ongoing. [ABSTRACT FROM AUTHOR]

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental condition that usually begins in childhood and is characterized by difficulty concentrating, hyperactivity, and impulsivity. We aim to investigate the connections between ADHD and dental health, highlighting how ADHD symptoms can contribute to poor oral hygiene and unhealthy eating habits, such as neglecting tooth brushing, but also excessive sugar consumption. These behavioral traits can have a significant impact on oral health, leading to an increased risk of dental disease, while increasing the risk of tooth decay, periodontal disease and dental trauma. Also discussed is the impact of anxiety and stress associated with ADHD upon oral health, including the increased risk of bruxism and other complications. We will focus on possible strategies and interventions to improve dental health in people with ADHD, emphasizing the importance of a multidisciplinary approach in the management of these patients.

This study applied a subtractive genomics approach to identify a potential drug target in the Porphyromonas gingivalis strain (ATCC BAA-308/W83). The aim was to characterize the whole proteome and hypothetical proteins (HPs) through structural, functional, and pathway predictions. The proteome was systematically reduced to identify essential proteins (EPs), non-homologous proteins (NHPs), and non-paralogous proteins (NPPs) while excluding those that were similar to the human proteome. Out of 1,836 proteins, the cluster database at high identity with tolerance algorithm identified 36 sequences as paralogous, having 80% identity. The resulting 1,827 proteins were compared to the human proteome using BLASTp (e-value 10−3), resulting in 1,427 NHPs. These were then aligned with the DEG database using BLASTp (e-value of 10−5), identifying 396 NHPs essential for pathogen survival. CELLO predicted the sub-cellular localization, and KEGG Automated Annotation Server identified potential metabolic pathways using a BLASTp similarity search of NHPs and EPs against the infrequently updated KEGG database. A total of 79 HPs essential for P. gingivalis were selected, and their molecular weights were determined. HPs were screened for metabolic pathway prediction, and the 3D structures of the proposed HPs were determined using homology modeling, and validation was performed. Only one HP (putative arginine deiminase) was qualified and found to be involved in the arginine and proline metabolic pathway.

Antimicrobial resistance is one of the largest threats to global health. In society as well as in healthcare facilities, antimicrobial resistance is rapidly increasing with the main reason being overuse and misuse of antibiotics combined with inadequate infection prevention. For humans, dental care accounts for about 10% of all antibiotic prescriptions, making it an important target for antibiotic stewardship interventions. Corresponding figures for veterinary care are currently lacking but dental disease is frequently diagnosed in small animals. An important first step in the work towards prudent use of antibiotics is to understand antibiotic prescription habits and through that estimate the adherence to veterinary antibiotic guidelines as well as the need for education, training, and improved policies. The aim of this article is to present the results of a multicentre point prevalence survey sent to Swedish IVC Evidensia practices during autumn 2021 to recognize the use of antibiotics associated with dental treatments in dogs, cats, and rabbits. During the study period, 4.4% of the dental patients in Swedish IVC Evidensia small animal veterinary practices received antibiotics. The most used antibiotics prescribed were ampicillin, amoxicillin, and clindamycin indicating an overall high level of compliance to veterinary dental guidelines. This article demonstrates that Swedish veterinarians use antibiotics prudently in small animal dentistry and the results may be used as a future global benchmark. [ABSTRACT FROM AUTHOR]

Early childhood is a crucial developmental phase of a child's well-being, which lays the foundation for their future growth. Lack of good oral practices may cause dental issues during this fundamental phase of development and have a long-lasting impact on a child's overall well-being. This cross-sectional study was conducted at a tertiary care hospital in Karachi, Pakistan, to explore oral health knowledge and practices among the caregivers of young children. A sample of 94 participants, including parents, caregivers, early childhood educators, and healthcare professionals (HCPS), was included through a convenient sampling technique. An online survey questionnaire was administered, which covered various aspects of oral hygiene practices to prevent common oral diseases among children. All statistical analyses were performed using SPSS 22.0. Statistical significance was accepted as p ≤0.05. Results of the study revealed no significant differences in oral health knowledge and practices based on age and gender. However, comparisons based on profession and roles showed a significant difference. Most participants agreed on the importance of regular oral hygiene practices. However, their opinions differed on certain oral hygiene practices, including the frequency of brushing and the timing of the first dental visit. This study underscores the importance of targeted education and interventions to improve oral health outcomes during the critical developmental phase of childhood. [ABSTRACT FROM AUTHOR]

Simple Summary: Domestic rabbits are one of the most commonly kept pets with a hypselodontic type of dentition, possessing teeth that grow throughout the animal's life. These animals often show signs of disease in the stomatognathic system. Dental disease can also affect the function of other organs and systems. The most common clinical signs of dental disease in domestic rabbits are the following: lack of appetite, weight loss, apathy, and difficulty chewing and swallowing food. These clinical signs are non-specific, and, therefore, a definitive diagnosis usually requires additional methods, such as an X-ray examination, a CT scan, MRI, and endoscopic examination. The most common dental disease found in this study's animals was malocclusion secondary to abnormal clinical crown abrasion and abnormal tooth growth. In domestic rabbits, osteomyelitis is a common complication of dental abscesses. Computed tomography is an invaluable diagnostic method in the diagnosis of dental disease and secondary diseases of the head area, such as inflammation of the nasal cavities or otitis media, in pet rabbits. Domestic rabbits have teeth that grow throughout the animal's life and are prone to disease. Clinical signs of dental disease in domestic rabbits are non-specific, and, therefore, a definitive diagnosis usually requires additional methods. This study was carried out on a group of 105 domestic rabbits aged 3 to 9 years. In total, 90 domestic rabbits with dental disease visible on CT images and other secondary diseases of the head area qualified for this study. Malocclusion was found in 57 (63.3%). Retrograde elongation of the tooth apices in the mandible was present in 39 (43.3%), and it was present in the maxilla in 48 (53%). Clinical tooth crowns were overgrown in 39 (43%). Dental abscesses were present in 54 (63%). Secondary to the presence of a dental abscess, osteomyelitis was found in 43 (79% of the animals with a dental abscess). Dental inflammatory resorption was found in 36 (40%). Secondary to dental disease, nasal cavity inflammation was found in 18 (20%). Otitis media was present in six (6.7%). The most common dental disease found in this study's animals was malocclusion secondary to abnormal clinical crown abrasion and abnormal tooth growth.

Summary : Periodontal disease and increased missing teeth were associated with incident vertebral fractures. In contrast, professional dental cleaning and frequent tooth brushing, was associated with a lower risk of vertebral fracture. Better oral hygiene care attenuated the risk associated with dental diseases. Purpose: To investigate the association between oral health and the risk of vertebral fractures. Methods: We included 2,532,253 individuals aged ≥40 years who underwent the Korean National Health Insurance Service health examinations in 2008 and followed up until December 31, 2017. We performed multivariable Cox proportional hazard regression analyses to evaluate the association between dental diseases and oral hygiene care and the risk of vertebral fractures. Results: Over the 9.3-year median follow-up, 1.46% (n = 36,857) experienced vertebral fractures. Individuals with dental diseases had a higher risk of vertebral fracture than those without (hazard ratio [HR] 1.04, 95% confidence interval [CI]: 1.02–1.07 for periodontal diseases; 1.02, 1.00–1.05 for dental caries; 1.12, 1.05–1.20 for ≥15 missing teeth). Good oral hygiene care was associated with a lower vertebral fracture risk (HR 0.89, 95% CI: 0.86–0.91 for ≥1 time/year [vs. <1 time/year] of professional dental cleaning; 0.90, 0.87–0.93 for ≥2 times/day [vs. 0–1 time/day] of toothbrushing). The combined dental diseases was significantly associated with an increased vertebral fracture risk, whereas combined oral hygiene care was associated with further risk reduction. Better oral hygiene care reduced vertebral fracture risk associated with dental diseases (all P <0.001). Conclusion: Periodontal disease, dental caries, and an increased number of missing teeth were independently associated with higher risks for vertebral fractures. Conversely, improved oral hygiene care, such as personal dental cleaning and frequent tooth brushing, may modify vertebral fracture risks associated with dental disease. [ABSTRACT FROM AUTHOR]

Objective: To determine the association between poor dental health and risk of oral cavity squamous cell cancer (OCSCC) at individual tumor subsites. Study Design: Case‐control and cross‐sectional Methods: A case‐control study was performed using a population‐based cohort in North Carolina (Carolina Head and Neck Cancer Epidemiology Study [CHANCE]). A secondary cross‐sectional analysis was performed with an institutional cohort (WashU/Siteman). Cases were adults with primary OCSCC and an identifiable tumor subsite. In the CHANCE cohort, controls were adults without head and neck cancer. In the Washington University/Siteman cohort, patients with tongue cancer served as the comparator group. We used number of missing teeth (categorized 0‐6, 7‐24, 25‐28) as a surrogate for poor dental health, which was self‐reported in CHANCE and measured on a pretreatment computed tomography scan in the WashU/Siteman study. Adjusted odds ratios (aORs) for missing teeth were estimated for each tumor subsite using binomial logistic regression models. Results: Near complete tooth loss (25‐28 teeth) was associated with a 3.5‐fold increased risk of alveolar ridge malignancy (aOR: 3.51; 95% confidence interval [CI]: 1.14‐11.01, P =.03) in the CHANCE study. This association was confirmed in our cross‐sectional analysis (WashU/Siteman study) where missing 25‐28 teeth was associated with an increased risk of alveolar ridge compared to tongue cancer (aOR: 4.60; 95% CI: 1.97‐11.10, P =.001). Conclusions: This study suggests an association between poor dental health and risk of alveolar ridge cancer independent of smoking, alcohol use, age, race, and sex. Future prospective and translational studies are needed to confirm this association and elucidate the mechanism of dental disease in alveolar ridge malignancies. [ABSTRACT FROM AUTHOR]

Abstract Aim This study aimed to assess the performance of OpenAI’s ChatGPT in generating diagnosis based on chief complaint and cone beam computed tomography (CBCT) radiologic findings. Materials and methods 102 CBCT reports (48 with dental diseases (DD) and 54 with neoplastic/cystic diseases (N/CD)) were collected. ChatGPT was provided with chief complaint and CBCT radiologic findings. Diagnostic outputs from ChatGPT were scored based on five-point Likert scale. For diagnosis accuracy, the scoring was based on the accuracy of chief complaint related diagnosis and chief complaint unrelated diagnoses (1–5 points); for diagnosis completeness, the scoring was based on how many accurate diagnoses included in ChatGPT’s output for one case (1–5 points); for text quality, the scoring was based on how many text errors included in ChatGPT’s output for one case (1–5 points). For 54 N/CD cases, the consistence of the diagnosis generated by ChatGPT with pathological diagnosis was also calculated. The constitution of text errors in ChatGPT’s outputs was evaluated. Results After subjective ratings by expert reviewers on a five-point Likert scale, the final score of diagnosis accuracy, diagnosis completeness and text quality of ChatGPT was 3.7, 4.5 and 4.6 for the 102 cases. For diagnostic accuracy, it performed significantly better on N/CD (3.8/5) compared to DD (3.6/5). For 54 N/CD cases, 21(38.9%) cases have first diagnosis completely consistent with pathological diagnosis. No text errors were observed in 88.7% of all the 390 text items. Conclusion ChatGPT showed potential in generating radiographic diagnosis based on chief complaint and radiologic findings. However, the performance of ChatGPT varied with task complexity, necessitating professional oversight due to a certain error rate.

Objective To research the effectiveness of deep learning techniques in intelligently diagnosing dental caries and periapical periodontitis and to explore the preliminary application value of deep learning in the diagnosis of oral diseases. Methods A dataset containing 2 298 periapical films, including healthy teeth, dental caries, and periapical periodontitis, was used for the study. The dataset was randomly divided into 1 573 training images, 233 validation images, and 492 test images. By comparing various neural network models, the MobileNetV3 network model with better performance was selected for dental disease diagnosis, and the model was optimized by tuning the network hyperparameters. The accuracy, precision, recall, and F1 score were used to evaluate the model's ability to recognize dental caries and periapical periodontitis. Class activation map was used to visualization analyze the performance of the network model. Results The algorithm achieved a relatively ideal intelligent diagnostic effect with precision, recall, and accuracy of 99.42%, 99.73%, and 99.60%, respectively, and the F1 score was 99.57% for classifying healthy teeth, dental caries, and periapical periodontitis. The visualization of the class activation maps also showed that the network model can accurately extract features of dental diseases. Conclusion The tooth lesion detection algorithm based on the MobileNetV3 network model can eliminate interference from image quality and human factors and has high diagnostic accuracy, which can meet the needs of dental medicine teaching and clinical applications.

Background and Objectives: Modernization and population aging have increased the prevalence of systemic diseases, such as diabetes and hypertension, which are often accompanied by various dental diseases.

Introduction: Dental disease is a common condition affecting horses. Its prevalence and characteristics among most of the common breeds of horses and donkeys have been investigated and described in the literature, but information about the prevalence and etiology of dental disease of miniature horses is sparse. Methods: To determine the prevalence and characteristics of dental disease of miniature horses, we performed oral and dental radiographic examinations on 100 miniature horses. The findings of these examinations were analyzed to determine the prevalence of dental disease and its correlation to age, sex, weight, body condition score, height at the withers, head length and head width. Older horses had a higher prevalence of dental disease, diastemata and crown elongations. Results: The most common dental diseases detected in this population were crown elongation, oral mucosal ulceration, diastemata, class 1 malocclusion and hypodontia. Horses with a high body condition score had an increased likelihood of having a class 1 malocclusion. Horses with wider heads had a higher prevalence of dental disease and class 1 malocclusions. Conclusion: Frequent oral examinations, starting at an early age, should be prioritized as a part of miniature horse preventive health care to decrease morbidity and slow progression of dental disease.

Summary: This case series describes the management of advanced occlusal caries of the maxillary cheek teeth in four horses. All horses presented with grade 4 caries, i.e., affecting cementum, enamel, dentine and the integrity of the tooth. Food packing in deep cavities on the occlusal surface were present in all horses. Two horses presented with pulpitis of teeth adjacent to the occlusal caries lesions. The carious lesions were mostly limited to the occlusal surface of maxillary cheek teeth, whereas the peripheral cementum to a large degree remained unaffected. Management of these cases included cleaning, flushing, and debriding of carious surfaces and placing a flowable resin composite on areas with extensive tooth loss to prevent food packing and further destruction of dental tissues. Endodontic therapy was performed in two cases. Some of the horses that exhibited clinical signs showed improvement after treatment and none of the cases showed deterioration of caries lesions. One horse showed complete resolution of occlusal caries. [ABSTRACT FROM AUTHOR]

To utilize standardized clinical veterinary methods to analyze dental health in a series of Roman dog maxillae and mandibles and to compare results to modern clinical data. 28 skulls of juvenile and adult dogs from three archaeological sites in Switzerland and Germany dating to the Roman period. Standardized examination was carried out, which included metric radiographic assessment to diagnose oral pathology and estimate age at death. In one case, CT analysis was undertaken. The estimated average age at death was between three and four years old. Tooth fracture, periodontal disease, the presence of non-vital teeth, and brachycephalic skull form were found in the sample. Tooth resorption was unexpectedly noted. The study provides valuable insights into the dental health of dogs in the Roman era. Compared to modern dogs, Roman dogs examined in this study appear to have a shorter lifespan but display a high rate of pathological dental disease, while disease patterns were very similar to those of modern dogs. Dogs with pronounced brachycephalic features were found. This pilot study is the first to use standardized clinical examination and recording techniques to assess dental health in dogs from archaeological contexts. It provides insight into the dental health of Roman era dogs and offers data upon which cross-populational studies can be initiated. The sample size and geographic location of the archaeological sites were limited. Subsequent standardized studies, preferably in as many different Roman Empire regions as possible, are recommended.

The documented increase in the occurrence of dental diseases in captive big cats over the past decades has necessitated the need to target dental medical research accordingly. The aim of this study was the systematic evaluation of dental and oral pathologies of lions and tigers which included intraoral dental radiography. Thirty-six animals of both sexes, ranging in age from nine months to 18 years, predominantly in circus husbandry, served as the basis of the present study, and their dental health status was investigated. The preliminary report and history, adspection of the awake animal, and examination under anesthesia provided important information. Eight animals were specifically presented for oral examination because of known dental disease. The remaining 28 animals were anesthetized for other medically necessary procedures, and each animal's oral and dental health status was also evaluated while under anesthesia. In the 28 animals that underwent routine oral cavity examination, pathological changes that had not previously been noticed were found in two-thirds of the animals (19/28). One-quarter of all the animals (9/36) had no abnormal oral cavity findings. Dentoalveolar trauma such as tooth fractures and abrasion (24/36) were diagnosed most frequently. The results highlight the importance of regular oral examinations in big cats. Furthermore, the results suggest that there is a relationship between husbandry conditions and the incidence of dentoalveolar trauma in captive big cats. [ABSTRACT FROM AUTHOR]

Naval armed forces are commonly prone to stressors during military activities which are associated with their working environment. This can adversely impact the oral health of these personnel. This scoping review aimed to explore the literature concerning oral health among naval personnel. Relevant articles that reported oral health among naval armed forces published from 1990 to December 2022 were retrieved from five main databases. Of the 641 articles searched, 15 met the inclusion and exclusion criteria. Occurrences of caries, periodontal disease and barodontalgia were high among the naval armed forces, with a significant number of dental emergencies during deployment and training operations. The dental diseases and emergencies experienced by the naval personnel on duty may influence their performance during missions. Given the far-reaching effects of dental diseases among personnel in the naval armed forces, further prospective studies with standardised report investigating oral health and dental diseases are recommended. Oral health services in the naval armed forces can also be improved by increasing the dentist-to-navy personnel ratio both at the military bases and on board the vessels during missions, as well as designing preventive strategies to improve oral health among the naval personnel.

Introduction The awareness of the dental ailments and its treatment modalities was initially assessed by means of questionnaire based epidemiological surveys. However, the advancement in technology will not only be used by the public to know about the importance of various dental ailments but also their treatment. On the other hand, the technology also utilizes to find out the awareness of the same among public. Google trends is a web engine based tool, provided by google. It allows the public to identify the popularity of a particular search term. Using this particular tool, we could identify the search trend of various dental terms pertaining to disease and treatment digitally. To evaluate the awareness of dental ailments and its treatments in Tamilnadu in 2020 and to compare the same, with that of previous decade to analyze the change in awareness over time. Material and Methods Google is the most commonly used search Engine by the general public worldwide. Hence we used Google search Engine to know the awareness of dental ailments and the treatment modalities among the general public. Five keywords were selected for each dental specialty. All the key words were run through google trends web engine. Results On the whole significantly highest searched terminology in Tamilnadu for the year of 2020 was extraction with 67 searches. Following this dental braces were the next commonly searched term with the count of 36. The significantly searched term for the year of 2010 was removable denture with 64 searches. The next commonly searched term was impaction with 56 searches and dental floss with 55 searches. Conclusion The current study is a novel attempt and paves a new platform to evaluate the awareness of disease, its trend and its treatment in dentistry and various other specialties.

Dental disease in sugar gliders (Petaurus breviceps) is understudied, with only limited clinical and pathological data available. An approximately 7-year-old female sugar glider presented to its primary care veterinarian for a decline in food intake, rapid weight loss and a mass involving the rostral mandible. At necropsy, the mandibular mass effaced most of the rostral mandible and adjacent musculature. Histologically, the mandible was disrupted by nodular infiltrates of variably degenerate neutrophils and macrophages encased in granulomatous inflammation and fibrous connective tissue. Within the neutrophilic cell population were segments of fragmented, necrotic bone and cloud-like colonies of gram-positive cocci. Aerobic culture yielded a heavy, pure growth of a gram-positive coccus morphologically consistent with those identified in the lesions, which was identified as a presumptively novel Kocuria sp by polymerase chain reaction and sequencing of the 16S rRNA gene. This is the first description of Kocuria infection in association with clinically significant pathology in an animal. Although isolated as a pure growth, Kocuria sp cannot be confirmed as the sole cause of lesion formation due to the case chronicity and potential for unculturable, polymicrobial infections. This report adds to our understanding of the clinical and pathological aspects of dental disease in sugar gliders. [ABSTRACT FROM AUTHOR]

Abstract Background Artificial intelligence (AI) has been introduced to interpret the panoramic radiographs (PRs). The aim of this study was to develop an AI framework to diagnose multiple dental diseases on PRs, and to initially evaluate its performance. Methods The AI framework was developed based on 2 deep convolutional neural networks (CNNs), BDU-Net and nnU-Net. 1996 PRs were used for training. Diagnostic evaluation was performed on a separate evaluation dataset including 282 PRs. Sensitivity, specificity, Youden’s index, the area under the curve (AUC), and diagnostic time were calculated. Dentists with 3 different levels of seniority (H: high, M: medium, L: low) diagnosed the same evaluation dataset independently. Mann-Whitney U test and Delong test were conducted for statistical analysis (ɑ=0.05). Results Sensitivity, specificity, and Youden’s index of the framework for diagnosing 5 diseases were 0.964, 0.996, 0.960 (impacted teeth), 0.953, 0.998, 0.951 (full crowns), 0.871, 0.999, 0.870 (residual roots), 0.885, 0.994, 0.879 (missing teeth), and 0.554, 0.990, 0.544 (caries), respectively. AUC of the framework for the diseases were 0.980 (95%CI: 0.976–0.983, impacted teeth), 0.975 (95%CI: 0.972–0.978, full crowns), and 0.935 (95%CI: 0.929–0.940, residual roots), 0.939 (95%CI: 0.934–0.944, missing teeth), and 0.772 (95%CI: 0.764–0.781, caries), respectively. AUC of the AI framework was comparable to that of all dentists in diagnosing residual roots (p > 0.05), and its AUC values were similar to (p > 0.05) or better than (p

Domestic rabbits have teeth that grow throughout the animal’s life and are prone to disease. Clinical signs of dental disease in domestic rabbits are non-specific, and, therefore, a definitive diagnosis usually requires additional methods. This study was carried out on a group of 105 domestic rabbits aged 3 to 9 years. In total, 90 domestic rabbits with dental disease visible on CT images and other secondary diseases of the head area qualified for this study. Malocclusion was found in 57 (63.3%). Retrograde elongation of the tooth apices in the mandible was present in 39 (43.3%), and it was present in the maxilla in 48 (53%). Clinical tooth crowns were overgrown in 39 (43%). Dental abscesses were present in 54 (63%). Secondary to the presence of a dental abscess, osteomyelitis was found in 43 (79% of the animals with a dental abscess). Dental inflammatory resorption was found in 36 (40%). Secondary to dental disease, nasal cavity inflammation was found in 18 (20%). Otitis media was present in six (6.7%). The most common dental disease found in this study’s animals was malocclusion secondary to abnormal clinical crown abrasion and abnormal tooth growth. In domestic rabbits, osteomyelitis is a common complication of dental abscesses. Computed tomography is an invaluable diagnostic method in the diagnosis of dental disease and secondary diseases of the head area, such as inflammation of the nasal cavities or otitis media, in pet rabbits.

IntroductionDental disease is a common condition affecting horses. Its prevalence and characteristics among most of the common breeds of horses and donkeys have been investigated and described in the literature, but information about the prevalence and etiology of dental disease of miniature horses is sparse.MethodsTo determine the prevalence and characteristics of dental disease of miniature horses, we performed oral and dental radiographic examinations on 100 miniature horses. The findings of these examinations were analyzed to determine the prevalence of dental disease and its correlation to age, sex, weight, body condition score, height at the withers, head length and head width. Older horses had a higher prevalence of dental disease, diastemata and crown elongations.ResultsThe most common dental diseases detected in this population were crown elongation, oral mucosal ulceration, diastemata, class 1 malocclusion and hypodontia. Horses with a high body condition score had an increased likelihood of having a class 1 malocclusion. Horses with wider heads had a higher prevalence of dental disease and class 1 malocclusions.ConclusionFrequent oral examinations, starting at an early age, should be prioritized as a part of miniature horse preventive health care to decrease morbidity and slow progression of dental disease.

Background: Periodontitis ranks as the sixth most prevalent global ailment, impacting around 750 million individuals and standing as a prominent cause of adult dental loss. This study aims to investigate the dental awareness, viewpoints, and recognition of severe oral ailments with potential systemic health implications among distinct medical specialists: Gynecologists, Diabetologists, and Psychiatrists. Materials and Methods: A questionnaire based survey among three groups of specialist's, viz. gynecologists (Group A), diabetologists (Group B), and psychiatrists (Group C) was done to gather insights into the participants' knowledge of periodontal disease and its links to systemic conditions. The collected data were subjected to descriptive statistical analysis using Microsoft excel 2013. Results: The findings revealed that 100% of diabetologists were cognizant of the correlation between periodontal health and its systemic implications. Among gynecologist's 67% recognized the relationship between periodontal health, pregnancy, and women's well-being. Meanwhile, the majority of psychiatrists demonstrated appropriate referral practices when necessary. In contrast, only 47% of diabetologists who were aware of the connection initiated referrals for oral health assessments by dentists. Conclusion: Enhancing awareness and referral rates to dental professionals could potentially foster improved oral health, impacting diverse medical conditions. However, there exists an opportunity to motivate patients to seek dental care independently of their primary healthcare provider's specialization. [ABSTRACT FROM AUTHOR]

Sugar-sweetened beverages (SSBs) increase chronic disease risk. We estimated the impact on employee health and health care spending of banning SSB sales in California-based health care organizations. We used survey data from a large, multisite health care organization in California, sampling 2,276 employees three months before and twelve months after a workplace SSB sales ban was imposed. We incorporated the survey data into a simulation model to estimate chronic disease incidence and costs. We estimated that an SSB ban as effective as the one observed would save about $300,000 per 10,000 people over ten years among similar employers, as a result of averted health care and productivity spending-after both SSB sales losses and non-SSB beverage sales gains were accounted for. Sales bans would typically need to reduce SSB consumption by 2.2 ounces per person per day for lost revenue to be fully offset if there were no increase in non-SSB beverage sales.

Abstract Background To determine the risk factors for the development of radiographic distal surface caries (rDSC) in patients who attend routine dental check-ups during an era of National Institute for Health Care Excellence third molar surgery guidelines. Methods Radiographs taken during routine dental examinations involving 1012 patients from Manchester, UK were accessed. Clinical parameters, oral health, patient demographics, and socioeconomic factors were assessed. Risk factors were identified by multivariate logistic regression analysis. Results The detected rate of rDSC was 63.9% and rDSC was distributed homogenously across all five socioeconomic groups (p = 0.425). Risk factors associated with rDSC (p

Background: Artificial intelligence (AI) has been introduced to interpret the panoramic radiographs (PRs). The aim of this study was to develop an AI framework to diagnose multiple dental diseases on PRs, and to initially evaluate its performance. Methods: The AI framework was developed based on 2 deep convolutional neural networks (CNNs), BDU-Net and nnU-Net. 1996 PRs were used for training. Diagnostic evaluation was performed on a separate evaluation dataset including 282 PRs. Sensitivity, specificity, Youden's index, the area under the curve (AUC), and diagnostic time were calculated. Dentists with 3 different levels of seniority (H: high, M: medium, L: low) diagnosed the same evaluation dataset independently. Mann-Whitney U test and Delong test were conducted for statistical analysis (ɑ=0.05). Results: Sensitivity, specificity, and Youden's index of the framework for diagnosing 5 diseases were 0.964, 0.996, 0.960 (impacted teeth), 0.953, 0.998, 0.951 (full crowns), 0.871, 0.999, 0.870 (residual roots), 0.885, 0.994, 0.879 (missing teeth), and 0.554, 0.990, 0.544 (caries), respectively. AUC of the framework for the diseases were 0.980 (95%CI: 0.976–0.983, impacted teeth), 0.975 (95%CI: 0.972–0.978, full crowns), and 0.935 (95%CI: 0.929–0.940, residual roots), 0.939 (95%CI: 0.934–0.944, missing teeth), and 0.772 (95%CI: 0.764–0.781, caries), respectively. AUC of the AI framework was comparable to that of all dentists in diagnosing residual roots (p > 0.05), and its AUC values were similar to (p > 0.05) or better than (p < 0.05) that of M-level dentists for diagnosing 5 diseases. But AUC of the framework was statistically lower than some of H-level dentists for diagnosing impacted teeth, missing teeth, and caries (p < 0.05). The mean diagnostic time of the framework was significantly shorter than that of all dentists (p < 0.001). Conclusions: The AI framework based on BDU-Net and nnU-Net demonstrated high specificity on diagnosing impacted teeth, full crowns, missing teeth, residual roots, and caries with high efficiency. The clinical feasibility of AI framework was preliminary verified since its performance was similar to or even better than the dentists with 3–10 years of experience. However, the AI framework for caries diagnosis should be improved. [ABSTRACT FROM AUTHOR]

Knossos was an important city on Crete and within Mediterranean networks during the Hellenistic, Roman, and Late Antique periods. However, there were significant social, cultural, and economic shifts that appear to have caused changes to daily lifeways, including diet. This paper sets out to explore dietary changes across these time periods by looking at dental caries, with reference also to antemortem tooth loss, calculus, and stable isotope data. This study also looks to contextualize these results using archaeological and textual information relating to diet. It presents a thorough methodological approach to the investigation and interpretation of caries and discusses some of the shortcomings of using a fragmentary and commingled skeletal assemblage. The Roman diet was more cariogenic than in the Hellenistic or Late Antique periods. The caries‐zone analysis of the teeth suggests that there may have been a greater addition of sugars to the diet in the Roman period, though the increased caries could also be due to improved preparation techniques and technologies producing a more refined and sticky carbohydrate diet. Such changes could be due to either increased connectivity making certain foods more readily available, the cultural changes in food consumption or dental hygiene due to the influx of merchants, colonists, migrants, and other newcomers to the Colonia Iulia Nobilis Cnosus that was Roman Knossos, or increased prosperity at the site in this period. There was a significant difference detected between females and males for caries indicating differential dietary practices between the sexes, which was most notable for the Roman period.

Background: To determine the risk factors for the development of radiographic distal surface caries (rDSC) in patients who attend routine dental check-ups during an era of National Institute for Health Care Excellence third molar surgery guidelines. Methods: Radiographs taken during routine dental examinations involving 1012 patients from Manchester, UK were accessed. Clinical parameters, oral health, patient demographics, and socioeconomic factors were assessed. Risk factors were identified by multivariate logistic regression analysis. Results: The detected rate of rDSC was 63.9% and rDSC was distributed homogenously across all five socioeconomic groups (p = 0.425). Risk factors associated with rDSC (p < 0.001) were identified as partially erupted mesio-angularly impacted mandibular third molars, third molars with compromised molar to molar contact points, loss of lamina dura of ≥ 2 mm, male gender, increasing age, and a higher modified Decayed Missing Filled Tooth score. Conclusion: rDSC was significantly associated with the angulation of third molars, the compromised contact position of the adjacent third molar, the periodontal status of the distal aspect of the second molar and the cumulative history of oral health in a population governed by specific third molar guidelines. An active approach to third molar surgical management could reduce rDSC and serve this population, irrespective of patients' socioeconomic or deprivation status. [ABSTRACT FROM AUTHOR]

Simple Summary: There has been an increase in domestic rabbit ownership in the recent years. The type of dentition of this exotic (non-traditional) animal pet, predisposes it to the development of Acquired Dental Disease (ADD), a disease that affects tooth quality, generates malocclusion, among other dental and non-dental consequences. The aim of this study was to assess the factors that modify the risk for ADD in domestic pet rabbits. For this, 1420 owned rabbits' clinical records from a private practice from 2018 to 2021 were used, recording several variables, including the clinical signs at diagnosis. ADD was detected in 25.4% of the individuals, mostly on their cheek teeth. In addition, age and sex (male) were found to be significant risk factors for ADD. In contrast, a free lifestyle and consuming hay in the diet were protective factors. Understanding the factors that modify the risk of ADD increases the chances of prevention and helps to improve the education of owners and/or guardians of domestic rabbits. Rabbits (Oryctolagus cuniculus) have elodont dentition, a characteristic that predisposes them to the development of Acquired Dental Disease (ADD), which is a multifactorial disease. The aim of this study was to assess the risk factors for ADD in domestic pet rabbits. To do this, a retrospective analysis of 1420 rabbits treated at a private practice during 2018–2021 was performed. For this, several variables were retrieved from clinical records, in addition to signology at the time of diagnosis. ADD was found on 25.4% of rabbits, mostly on their cheek teeth. In addition, age (OR = 1.029; 95% CI = 1.023–1.035; p < 0.001) and sex (male) (OR = 1.591; 95% CI = 1.226–2.064; p < 0.001) were found to be significant risk factors for ADD. In contrast, a free lifestyle (OR = 0.565; 95% CI = 0.362–0.882; p = 0.012) and consuming hay in the diet (OR = 0.323; 95% CI = 0.220–0.473; p < 0.001) were protective factors. In conclusion, ADD has a high prevalence and is usually underdiagnosed, highlighting the need for an exhaustive evaluation of patients during the clinical examination. This study improves our knowledge of ADD and its prevention. [ABSTRACT FROM AUTHOR]

Purpose: Special needs children presenting with dental problems were penalised during the Covid-19 pandemic due to the reduction of clinical activity and the risks of nosocomial infection. The aim of this study is to evaluate the impact of the pandemic on oral healthcare in paediatric special needs patients. Methods: We retrospectively assessed and compared the outpatient clinic activity and dental procedures performed under general anaesthesia in children with special needs at Brescia Children's Hospital (Italy) in 2019, 2020, and 2021. Any delay between expected waiting time based on assigned priority and surgery was recorded. The efficacy of the protocol adopted to reduce the spread of Covid-19 was evaluated by reporting any infections in patients, parents, and health care providers. Results: In 2020, 270 outpatient visits were performed, and 40 patients were treated under general anaesthesia, with a 26% and 65% reduction, respectively, compared to 2019. In 2021, 362 visits were performed (similar to 2019) and 48 patients were treated under general anaesthesia (58% compared to 2019). The mean delay in the planned treatment was 1.0 month in 2019 (pre-pandemic period), 2.1 months in 2020, and 1.1 month in 2021. No cases of Covid-19 infection were reported in the cohort of patients and parents or among the operators related to nosocomial infection. Conclusions: The Covid-19 pandemic has profoundly reduced the activity of general anaesthesia in paediatric special need patients during 2020, with a gradual return to normal pre-pandemic activity in 2021. The adopted protocol prevented the spread of COVID-19 during hospitalisation. [ABSTRACT FROM AUTHOR]

Abstract Background Scientific knowledge regarding alpaca dentistry is relatively limited despite its clinical implications. The present gap in available supportive data leads to limited treatment options for dental pathology in alpacas in comparison to other species. The main goal of this study was to gain novel insights into the general and pulp morphology of maxillary cheek teeth to allow development of more advanced treatment strategies in the future. Also, the risk of causing pulp exposure when floating maxillary cheek teeth was of particular interest. Concurent research focusing on the anatomy of mandibular cheek teeth has been performed accordingly. The results obtained in mandibular teeth are expected to be non-extrapolatable because of the structural differences between mandibular and maxillary teeth. Results Pulp morphology of maxillary cheek teeth showed great variation. A common pulp chamber was identified in 46/83 (55.4%) teeth with a mean dental age of 2 years and 7 months (± 2 years and 5 months). Pulpal segmentation was more commonly observed in teeth of increasing age. Full columnar segmentation was seen in 33/69 teeth (47.8%), whereas within-column segmentation was observed in 36/83 teeth (43.4%). Age and degree of segmentation of the pulpal tissue varied greatly according to Triadan position. Physical contact between roots of adjacent teeth was found in the majority of examined molars (range 82–94%) which resulted in morphological adaptations at the level of the root tips. The measured sub-occlusal dentinal thickness was as low as 0.46 mm above pulp horn 2 in a 14 years and 11 months old Triadan 09, emphasizing the risk of pulp exposure attributed to dental floating. Conclusion This study offers an objective description of age-dependent maxillary cheek teeth pulp morphology in alpacas. Current findings are of great value to provide a basis for the development of tooth-saving techniques as a treatment for dental disease in this species. Observed physical contact between the roots of different examined molars may be a facilitating factor in the spread of apical infection in chronically diseased cases. Finally, a conservative approach regarding dental floating is recommended in order to avoid iatrogenic damage to pulp tissue.

this research seeks to investigate the impact the industrial revolution had on the population of England. Pre-existing skeletal data from 1154 pre-Industrial (1066–1700 CE) and 4157 industrial (1700–1905) skeletons from 21 cemeteries (N = 5411). Context number, sex, age-at-death, stature and presence/absence of selected pathological conditions were collated. The data were compared using chi square, Kolmogorov-Smirnov, t-tests and logistic regression (α = 0.01). There was a statistically significant increase in cribra orbitalia, periosteal reactions, rib lesions, fractures, rickets, osteoporosis, osteoarthritis, enamel hypoplasia, dental caries and periapical lesions in the industrial period. Osteomyelitis decreased from the pre-industrial to industrial period. Our results confirm the industrial revolution had a significant negative impact on human health, however the prevalence of TB, treponemal disease, maxillary sinusitis, osteomalacia, scurvy, gout and DISH did not change, suggesting these diseases were not impacted by the change in environmental conditions. This is the largest study of health in the industrial revolution that includes non-adults and adults and considers age-at-death alongside disease status to date. This data supports the hypothesis that the rise of industry was associated with a significant decline in general health, but not an increase in all pathological conditions. [ABSTRACT FROM AUTHOR]

Objectives: Dental diseases are a major problem in cats and often necessitate tooth extraction. Medical-grade honey (MGH) has antimicrobial and wound-healing properties, and therefore the aim of this study was to investigate whether intra-socket application improved healing after tooth extraction. It was postulated that applying MGH would reduce inflammation, improve the viability of the surgical flap and enhance healing following tooth extraction. Methods: A prospective randomised controlled trial was performed in client-owned cats undergoing bilateral tooth extractions of the same element of the canine or (pre)molar tooth. A split-mouth design was used in which every animal served as its own control. After surgical extraction of the elements, the sockets on one side were filled with an MGH-based ointment (L-Mesitran Soft), whereas the contralateral side received no treatment (control). A mucoperiosteal flap was used on both sides, and simple interrupted monofilament sutures were placed. No antimicrobial drugs were administered. Clinical parameters (inflammation/redness, flap viability and wound healing) were subjectively analysed on days 3 and 7 post-extraction by a veterinarian blinded to the treatment. Results: Twenty-one cats were included. MGH significantly decreased signs of inflammation (P <0.01), improved mucoperiosteal flap viability (P <0.01) and promoted wound healing (P = 0.01), at both time points. MGH was easy to apply and there were no adverse events. Conclusions and relevance: Intra-socket application of MGH after tooth extraction positively affects the surgical wound, as it reduces redness, improves flap viability and enhances wound healing. Applying MGH represents a potent adjuvant therapy to support intra-oral wound healing after tooth extraction. [ABSTRACT FROM AUTHOR]

Dental pathology is among the most ubiquitous diseases in cats of all ages. Dental pain is yet to be fully understood in cats and therefore its presence is often missed. To better understand feline dental disease as a pain trigger during routine examination and whether disease severity correlates to the degree of pain, a 6-month prospective study in a cats' only veterinary hospital in Portugal was conducted. Sixty-four cats that randomly presented for different clinical procedures were evaluated. Dental and periodontal abnormalities (primary dental parameters, PDP), as well as clinical signs related to dental pain (secondary dental parameters, SDP), were assessed. All cats underwent an oral cavity examination, upon which, the Feline Acute Pain Scale from Colorado State University Veterinary Teaching Hospital (CPS), was used in order to assess pain. Six PDP (periodontal disease, gingival index, calculus index, tooth resorption, tooth fracture and missing teeth) and five SDP (mouth discomfort, halitosis, hypersalivation, difficulty in holding food and several attempts at prehension of food), were compared with CPS pain scores. All SDP were significantly associated to higher CPS pain scores (p < 0.05). The number of missing teeth was significantly associated to higher CPS pain scores (p < 0.0001). A trend was observed between higher CPS pain scores and tooth resorption (p = 0.08). This study concluded that cats with dental disease feel pain during clinical examination and the pain increases as the severity of the disease progresses. [ABSTRACT FROM AUTHOR]

Background: This population‐based cohort study investigated dental procedures in the hospital setting in Western Australian children with or without intellectual disability (ID) and/or autism spectrum disorder (ASD) aged up to 18 years. Considering previously reported disparities in dental disease between Indigenous and non‐Indigenous Australian children, this study also investigated the effect of Indigenous status on dental procedures. Methods: Data on Western Australian live births from 1983 to 2010 from the Midwives Notification System were linked to the Intellectual Disability Exploring Answers database and the Hospital Morbidity Data collection. Primary admissions for relevant dental diagnoses were identified, and treatment procedures for dental hospitalization were investigated. Descriptive statistics and Pearson's chi‐squared test of independence were used for analysis. Results: Overall, 76 065 episodes of dental hospitalization were recorded. Amongst children with ID and/or ASD, Indigenous children experienced more extractions and fewer restorations (68.7% and 16.2%) compared to non‐Indigenous children (51.5% and 25.9%). After 6 years, extraction occurred less often in children with ID and/or ASD than in those without, where most surgical dental extractions were in the age group of 13–18 years. Conclusions: This study indicates a need for further improvements in access to dental services and the quality of care provided in hospitals for children with ID/ASD. There is also concern that more vulnerable Indigenous and all disadvantaged children are receiving an inadequate level of dental services resulting in more emergency dental hospitalization and invasive treatment.

Background: Schools in Chennai are run publicly by the government or run privately, some with financial aid from the government in Tamil Nadu, a southern state of India. There are various systems of education – CBSE, Anglo Indian Board, ICSE Board, NIOS Board, Matriculation, Montessori, and State Board. From these, a massive study was conducted among 100,620 corporation school (state-run) students in the district of Chennai to find the prevalence of various dental diseases among them. Aim: To evaluate and compare the prevalence of various dental diseases among the corporation school children from different zones of Chennai city. Materials and Methods: The study was carried out for a period of about 15 months. It involved diagnosis, therapeutics, and referral to the state-run dental hospital for further follow-up. The district of Chennai was divided into ten zones. The school students, zone-wise, were screened, diagnosed and the required treatments were done at the venue or were referred to the higher center for further examination or treatment. The data collected were divided into zone-wise categories on the basis of disease occurrence and treatment/referral done and were tabulated. Results: The result obtained was that an astounding 74.36% of corporation school students were afflicted with some form of dental disease. Conclusion: Various associated factors such as lower socioeconomic status of the parents, educational background of the parents, dental education, and awareness among the school students could play major roles in the status of dental health among the corporation school children.

Background: Dental disease detection is essential for the diagnosis of dental diseases. Objective: This research compares the Mamdani fuzzy logic and Naïve Bayes in detecting dental diseases. Methods: The first is to process data on dental disease symptoms and dental support tissues based on complaints of toothache consulted with experts at a community health centre (puskesmas). The second is to apply the Mamdani fuzzy logic and the Naïve Bayes to the proposed expert system. The third is to provide recommended decisions about dental diseases based on the symptom data inputted into the expert system. Patient data were collected at the North Cilacap puskesmas between July and December 2021. Results: The Mamdani fuzzy logic converts uncertain values into definite values, and the Naïve Bayes method classifies the type of dental disease by calculating the weight of patients' answers. The methods were tested on 67 patients with dental disease complaints. The accuracy rate of the Mamdani fuzzy logic was 85.1%, and the Naïve Bayes method was 82.1%. Conclusion: The prediction accuracy was compared to the expert diagnoses to determine whether the Mamdani fuzzy logic method is better than the Naïve Bayes method. [ABSTRACT FROM AUTHOR]

Machine Learning and Deep Learning, the powerful weapons of Artificial Intelligence plays crucial role and major contributions in almost all the sectors using sophisticated technological framework with an insight to unlock the needs of business enacting decisions where data patterns holds a main role right from data gathering and explorations to visualization and predictions. Recently it is also a predominating technology used vigorously in various health sectors like medical, dental and allied health services as an aid to develop tools for decision making in data analytics and exploration, disease prediction and control, data analytics and treatment planning. Major research on this area was done in past contributing good frameworks for the predictions of Breast cancer, Rheumatoid Arthritis, Osteoporosis, Diabetes, Sarcoidosis, Graves' disease, AIDS, Psoriasis and many more. The current research paper is a result of using such Machine Learning approaches for the prediction of Periodontitis, a most common gum disease which leads to severe complications like tooth supporting structure loss like bone loss around tooth, ligament loss and finally the tooth loss if left untreated. In the current paper, a dataset size of 206 records of diabetic and non-diabetic periodontitis patients were collected with the measurable parameters like age, sex, oral hygienic status, tooth mobility, periodontal index, gingival index, furcation, alveolar bone loss, pocket depth and other parameters were taken and implemented. Supervised machine learning algorithms for classification like Support vector machine, Na¨ıve Bayes, Random forest, Logistic regression, decision tree and K Nearest neighbor algorithms were used and implemented in python using jupyter notebook for the prediction of periodontitis and obtained accuracies of 96.7%, 95.1%, 96.7%, 93.5%, 96.7% and 98.3% respectively. The current paper demonstrates how the dataset was collected and implemented using Machine learning approach in dentistry for obtaining a suggestible predictable model for periodontitis also compares all the models mentioned for their efficiency and accuracies.

Background: Patients with high dental anxiety are found to visit dental offices less frequently and have a higher number of severely diseased teeth so they are at a greater need for intensive oral care and rehabilitation., Objectives: The aim of this study was to assess the prevalence of dental anxiety and its impact on the dental status of Nepali adult patients., Material and Methods: A semi-structured questionnaire of the Modified Dental Anxiety Scale (MDAS) in the Nepali version was used for data collection. The data analysis was done using Statistical Package for Social Sciences (SPSS IBM, Chicago, IL, USA, version 24). Variables were calculated as frequency and percentage, while the comparisons of different factors were done using the ANOVA and t-test. A difference with p < 0.05 was considered statistically significant., Results: The study population consisted of 446 subjects, among them 205 were male (45.96%), 241 were female (54.04%), 357 (80.04%) were married, and 222 (49.78%) were employed. The mean age of the patients was 41.24 years (ranging between 18 and 79 years). Only 41 subjects (9.19%) showed high dental anxiety (MDAS ≥ 19). The mean MDAS for the total study population was 10.81. The highest mean MDAS was seen in the age group 30-39 (11.78) and the lowest mean MDAS was seen in the age group 40-49 (9.64). While comparing dental anxiety among genders, dental anxiety was higher in females (mean MDAS = 11.78) compared to males (mean MDAS = 9.67). Patients having high dental anxiety had a significantly higher number of decayed teeth (p-value = 0.001, t-test)., Conclusion: Oral health and dental status both are negatively affected by dental anxiety. It interferes with dental attendance, service delivery, prevention of dental diseases, and early diagnosis. Thus, dental practitioners have a major role to play in the management of dental anxiety., (© 2024 The Author(s). Clinical and Experimental Dental Research published by John Wiley & Sons Ltd.)
