Towards dental diagnostic systems: Synergizing wavelet transform with generative adversarial networks for enhanced image data fusion.

The advent of precision diagnostics in pediatric dentistry is shifting towards ensuring early detection of dental diseases, a critical factor in safeguarding the oral health of the younger population. In this study, an innovative approach is introduced, wherein Discrete Wavelet Transform (DWT) and Generative Adversarial Networks (GANs) are synergized within an Image Data Fusion (IDF) framework to enhance the accuracy of dental disease diagnosis through dental diagnostic systems. Dental panoramic radiographs from pediatric patients were utilized to demonstrate how the integration of DWT and GANs can significantly improve the informativeness of dental images. In the IDF process, the original images, GAN-augmented images, and wavelet-transformed images are combined to create a comprehensive dataset. DWT was employed for the decomposition of images into frequency components to enhance the visibility of subtle pathological features. Simultaneously, GANs were used to augment the dataset with high-quality, synthetic radiographic images indistinguishable from real ones, to provide robust data training. These integrated images are then fed into an Artificial Neural Network (ANN) for the classification of dental diseases. The utilization of the ANN in this context demonstrates the system's robustness and culminates in achieving an unprecedented accuracy rate of 0.897, 0.905 precision, recall of 0.897, and specificity of 0.968. Additionally, this study explores the feasibility of embedding the diagnostic system into dental X-ray scanners by leveraging lightweight models and cloud-based solutions to minimize resource constraints. Such integration is posited to revolutionize dental care by providing real-time, accurate disease detection capabilities, which significantly reduces diagnostical delays and enhances treatment outcomes.

Automated orofacial virtual patient creation: A proof of concept.

OBJECTIVES: To (1) construct a virtual patient (VP) using facial scan, intraoral scan, and low-dose computed tomography scab based on an Artificial intelligence (AI)-approach, (2) quantitatively compare it with AI-refined and semi-automatic registration, and (3) qualitatively evaluate user satisfaction when using virtual patient as a communication tool in clinical practice. MATERIALS AND METHODS: A dataset of 20 facial scans, intraoral scans, and low-dose computed tomography scans was imported into the Virtual Patient Creator platform to create an automated virtual patient. The accuracy of the virtual patients created using different approaches was further analyzed in the Mimics software. The accuracy (% of corrections required), consistency, and time efficiency of the AI-driven virtual patient registration were then compared with the AI-refined and semi-automatic registration (clinical reference). User satisfaction was assessed through a survey of 35 dentists and 25 laypersons who rated the virtual patient's realism and usefulness for treatment planning and communication on a 5-point scale. RESULTS: The accuracy for AI-driven, AI-refined, and semi-automatic registration virtual patient was 85%, 85%, and 100% for the upper and middle thirds of the face, and 30%, 30%, and 35% for the lower third. Registration consistency was 1, 1 and 0.99, and the average time was 26.5, 30.8, and 385 s, respectively (18-fold time reduction with AI). The inferior facial third exhibited the highest registration mismatch between facial scan and computed tomography. User satisfaction with the virtual patient was consistently high among both dentists and laypersons, with most responses indicating very high satisfaction regarding realism and usefulness as a communication tool. CONCLUSION: The AI-driven registration can provide clinically accurate, fast, and consistent virtual patient creation using facial scans, intraoral scans, and low-dose computed tomography scans, enabling interpersonal communication. CLINICAL SIGNIFICANCE: Using AI for automated segmentation and registration of maxillofacial structures leads to clinically efficient and accurate VP creation, opening the doors for its widespread use in diagnosis, treatment planning, and interprofessional and professional-patient communication.

The Impact of Orthodontic Adhesive Containing Resveratrol, Silver, and Zinc Oxide Nanoparticles on Shear Bond Strength: An In Vitro Study.

Introduction The goal of orthodontic treatment is to provide patients with esthetic smiles and functional occlusion. Despite best efforts and continuous evolution of materials, white spot lesions present a persistent hindrance to the desired treatment outcome. Nanoparticles have shown efficacy in reducing microbial activity; however, currently, there is a need for natural anti-cariogenic compounds with minimal side effects. Resveratrol is a natural compound belonging to the polyphenol group and has shown promising anti-microbial efficacy. This study aimed to evaluate the influence of dentin bonding agents incorporated with the following three different nanoparticles on shear bond strength: silver nanoparticles (Ag-Np), zinc oxide nanoparticles (ZnO-Np), and resveratrol nanoparticles (RSV-Np). Materials and methods A total of 40 premolar teeth therapeutically extracted were assigned to four equal groups of n=10 each. Groups 1, 2, and 3 used experimental adhesives doped with silver, zinc oxide, and resveratrol nanoparticles, respectively. Group 4 was bonded using unmodified adhesive. The bonded teeth were then subjected to shear bond strength (SBS) testing which was measured using a Universal Testing Machine (model no. UNITEST-10; Pune, India: ACME Engineers). Statistical analyses were performed using SPSS version 21 (Armonk, NY: IBM Corp.), employing one-way ANOVA and Tukey's post-hoc test for pairwise comparisons. Results Shear bond strength testing revealed that the control group with unmodified adhesive (8.6 MPa) had the highest SBS, followed by RSV-Np (7.6 MPa), Ag-Np (6.3 MPa), and ZnO-Np (5.65 MPa). Although the experimental groups demonstrated decreased SBS compared to the control, the values for Ag-Np and RSV-Np fell within the acceptable range. Conclusion Resveratrol nanoparticles had the least impact on shear bond strength among the experimental groups. These findings suggest that the incorporation of resveratrol nanoparticles in dentin bonding agents can provide anti-cariogenic effect without significantly impacting the adhesive's mechanical properties thereby providing a new and promising alternative to synthetic nanoparticles. Further studies are recommended to optimize the balance between anti-microbial efficacy and bond strength in clinical applications.

Present state and perceived future use of teledentistry in long-term care facilities in Japan: A cross-sectional study.

Objectives: Teledentistry could be effective in managing oral health through the provision of oral hygiene instruction and diagnostic services. This study aimed to assess the perception and usefulness of teledentistry in Japanese long-term care facilities. Methods: We conducted a questionnaire survey to compare related factors of the usefulness of teledentistry and identify issues in its implementation. We chose 1000 facilities using a stratified random sampling method. The questionnaires were sent to the facilities in August 2021 and collected in December of the same year. Responses to the questionnaire items regarding the usefulness of teledentistry for oral management were divided into three groups according to the answer: perceiving teledentistry as "useful," "not useful," or "neither," including facilities that do not currently use teledentistry. Results: In total, 26.1% (261) responded to the questionnaire, and among these, 184 facilities answered the question regarding the usefulness of teledentistry. Only two of these facilities implemented teledentistry. Facilities with dental hygienists (p = 0.040) and those that receive insured medical treatment: reimbursement for oral feeding maintenance II (p = 0.040) tended to perceive teledentistry as useful in the management of patients with coronavirus disease. The higher the number of services that responded to the question "what kind of services do you think can be provided via teledentistry?" the higher the percentage of "useful" responses. Conclusions: Although only a few facilities use teledentistry, many long-term care facilities perceive it as useful even without using it. The presence of dental hygienists and interprofessional work done with reimbursement for oral feeding maintenance II contributed to the perception of the usefulness of teledentistry in long-term care facilities.

Understanding the role of a general education course Oral Science in establishing oral health knowledge and behaviors among undergraduate students from different majors: a questionnaire-based study.

BACKGROUND: The general education course, Oral Science, has been offered by Guanghua School of Stomatology, Sun Yat-sen University for many years in order to improve students' knowledge of oral health. Information about the oral health knowledge, status, and behaviors among undergraduates who had taken Oral Science was collected to evaluate the impact of this course, and to provide a basis for further improvement of the course teaching quality. METHODS: Undergraduates taking Oral Science as an elective course were selected as the research subjects. The research time is the second semester of the 2022 academic year, from February 2023 to June 2023. Undergraduates who had not taken the course served as the control group. To investigate the oral health knowledge, status, and behaviors among undergraduate students who have taken the general education course of Oral Science, course students and non-course students were asked to fill out the same questionnaire at both the beginning and end of semester. The answer scores and accuracy of these two groups were compared and analyzed. Before and after the first lesson, and at the end of the semester, course students were asked to fill out the same oral knowledge questionnaire. Another questionnaire was released in week 10 to collect the data of the course students' oral health status and behaviors. The control group completed the same oral knowledge questionnaire at the beginning and end of the semester, respectively. SPSS 20.0 statistical software was used to analyze the data. Statistical significance level was set at 0.05 for all tests. RESULTS: At the beginning of the semester, there was no significant difference in the accuracy of the 16 questions nor the scores between two groups (P > 0.05). After one semester of learning, the accuracy of the 16 questions answered by the course students at the end of the semester was significantly higher (P < 0.05), as well as the score of the course students. CONCLUSION: The general education course of Oral Science can significantly improve undergraduates' general knowledge of dentistry and effectively improve their oral hygiene behavior.

Validation of the Polish version of an Ageism Scale for Dental Students (ASDS-PL).

BACKGROUND: Ageism is one of the common forms of discrimination and prejudice. It has also been shown to be present in health professionals, including doctors, nurses, and medical students. AIMS: The aim of this study was to translate the Ageism Scale For Dental Students (ASDS) into Polish, perform a culture adaptation, and conduct a preliminary validation analysis. METHODS: The survey was administered to 202 third-, fourth-, and fifth-year students at the Jagiellonian University (No. 1072.6120.283.2020). Data were analyzed using principal components analysis (PCA) with an oblique, Promax rotation, and confirmatory factor analysis (CFA). Cronbach's alpha (α) was calculated to check the internal consistency reliability. Discriminant validity was analyzed using the Mann-Whitney and Kruskal-Wallis test. RESULTS: PCA produced a 10-item scale distributed into three factors, which explains 59.52% of the total variance. Factor 1 ("preconceived notions about dental treatment") contained four items (α = 0.703), Factor 2 ("cost-benefit of providing care for older patients")-four items (α = 0.660) and Factor 3 ("dentist-older patient interaction")-two items (α = 0.662). CFA confirmed that the model is a good fit (RMSE = 0.058, 90% CI from 0.014 to 0.092, CFI = 0.950, and TLI = 0.926). The discriminant validity showed statistically significant differences in factors or individual items related to the year of the study, gender, and having a history of living with an older person(s) or an older patient(s) treated. CONCLUSION: The validation of the ASDS conducted in Poland identified 10 items with sufficient validity and reliability.

Big Data in Epidemiology: Brave New World?

Epidemiology is experiencing a significant shift toward the utilization of big data for health monitoring and decision-making. This article discusses the recent example of the World Health Organization (WHO) global oral health status report and regional summaries, which faced criticisms due to its reliance on big data from the Global Burden of Disease (GBD) study. We address the arguments for and against the use of big data in epidemiology and provide an assessment of the value and limitations of big data epidemiology. Moreover, we provide recommendations as to how the oral health community should reconcile traditional epidemiologic approaches with big data and advanced data analytics. This Perspective article highlights the challenges of the current epidemiologic landscape, the potential of big data, and the need for a balanced approach to data utilization in epidemiology.

Improving Healthcare in South Texas Rural Communities: An Interprofessional Initiative for Primary Care Dental and Medical Residents.

OBJECTIVE: To enhance primary care dentistry and medicine residents' didactic knowledge, communication skills to address patient's healthcare needs, and collaboration among healthcare professionals, while increasing confidence in integrating primary care skills into their clinical practice. METHODS: An Interprofessional Education workshop was organized to enhance didactic knowledge and learning of 42 primary care dentistry (PCD) and family and community medicine (FCM) residents on topics including addressing facial and dental trauma in adults, managing patients with alcohol use and abuse, pain control and prescription opioid use in dentistry, and opioid use disorder and treatment. An online survey was administered before and after the workshop to assess changes in knowledge, confidence, and future intentions to incorporate targeted primary care skills learned during the workshop into clinical practice and to elicit residents' perceptions of workshop quality. Overall scale means were assessed by chi-square tests for knowledge scales and analysis of variance for confidence and career intentions scales, significance levels were set at 0.05. RESULTS: Pre-workshop assessments were completed by all attendees while post assessments received a response rate of 83.3%. Both PCD and FCM residents reported an increase in their knowledge (p < 0.05) and confidence (p < 0.05) in providing care for patients with facial/dental trauma, identifying signs of opioid abuse, addressing alcohol abuse, and understanding the referral processes following the workshop. While an overall increase was noted regarding intentions to incorporate skills learned during the workshop into practice by the PCD (pre-course = 4.33, post-course = 4.42) and FCM (pre-course = 4.55, post-course = 4.73) residents, the differences were not statistically significant differences. CONCLUSIONS: The interprofessional education workshop for PCD and FCM residents enhanced their knowledge, confidence, and future intentions to incorporate primary care skills into clinical practice and improve patient outcomes.

Exploring Dental Fusion in Primary Dentition: A Pediatric Dental Perspective.

Developmental anomalies of dentition includes abnormalities in teeth size, shape, structure, and number. Dental fusion is one such condition and is one of the most important and frequent developmental dental anomalies that can affect children's oral health. This condition can present various clinical challenges, including aesthetic concerns, occlusal disturbances, and potential impacts on the development and eruption of permanent teeth. The etiology of dental fusion is multifactorial, involving genetic, environmental, and possibly mechanical factors during tooth development. Diagnosis is done based on clinical examination and radiographic imaging to differentiate fusion from other similar anomalies such as gemination and concrescence. The present case report describes dental fusion in primary teeth seen in two young pediatric patients. These case reports aim to provide an overview of the prevalence, diagnosis, and management strategies for fusion in primary teeth, emphasizing the importance of a Pediatric Dentist in optimizing outcomes for affected children.

Agências de regularização técnica odontológica em relação ao manejo clínico em crianças: uma revisão de literatura / Dental technical regularization agencies in relation to management clinic in children: a review of the literature

O manejo clínico em Odontopediatria é individual, podendo variar nas diversas culturas mundiais. O objetivo desta revisão de literatura é reunir as principais diretrizes de diferentes países ao redor do mundo, incluindo o Brasil, visando identificar como em cada lugar o uso das técnicas de comportamento são aplicadas e sua eficiência. Inicialmente, foram selecionados os principais guias nacionais e internacionais, sendo eles retirados da Associação Internacional de Odontopediatria (IAPD) e Associação Americana de Odontopediatria (AAPD), além de artigos de diferentes países e continentes, como Argentina, Brasil, Europa e Ásia, também foram analisados se o protocolo dos principais guias estão condizentes com os protocolos do Departamento de Clínica Infantil da Faculdade de Odontologia de Ribeirão Preto - USP. Os resultados obtidos nos guias para manejo clínico odontológico brasileiro, americano, internacional e os artigos estudados recomendam inicialmente utilizar técnicas menos invasivas, com o intuito proporcionar um atendimento tranquilo e sem criar traumas para a criança, uma vez que muito do comportamento não cooperativo vem de experiências anteriores traumáticas. Entretanto, técnicas avançadas podem ser utilizadas para casos mais desafiadores. Concluímos com o estudo dos guias e artigos, que o cirurgião dentista possui diversas técnicas a serem aplicadas para que o atendimento infantil seja atraumático e restabelecer saúde ao paciente.

Clinical management in Pediatric Dentistry is individual and varies across different cultures around the world. The objective of this literature review is to bring together the main guidelines from different countries around the world, including Brazil, aiming to identify how the use of behavioral techniques are applied and their efficiency in each place. Initially, the main national and international guides were selected, taken from the International Association of Pediatric Dentistry (IAPD) and the American Association of Pediatric Dentistry (AAPD), as well as articles from different countries and continents, such as Argentina, Brazil, Europe and Asia, as well as It was analyzed whether the protocols of the main guides are consistent with the protocols of the Children's Clinic Department of the Faculty of Dentistry of Ribeirão Preto - USP. The results obtained in the guides for Brazilian, American and international dental clinical management and the articles studied recommend initially using less invasive techniques, with the aim of providing calm care and without creating trauma for the child, since much of the uncooperative behavior comes from previous traumatic experiences. However, advanced techniques can be used for more challenging cases. We conclude from studying the guides and articles that the dental surgeon has several techniques to be applied so that child care is atraumatic and restores health to the patient.

Analysis of palatal rugae pattern and maxillary sinus index for gender determination.

Correlation between rugoscopy and lateral cephalometric radiographic technique for gender determination is of interest. A cross sectional study was conducted on 100 subjects within an age group of 20 to 50 years. Distribution of rugae patterns and morphometric analysis of maxillary sinus was done for gender correlation. Wavy curved and straight rugae patterns were observed to be more in female gender as compared to males. The mean MSI was higher in females (1.32) when compared with males (1.26). Both the morphometric analysis of maxillary sinus and rugoscopy has been proved to be a valuable tool in the assessment of sexual dimorphism. But, morphometric analysis of maxillary sinus is relatively a new and reliable method for gender determination using maxillary sinus index.

Effectiveness of Different Oral Health Interventions on Plaque and Gingivitis Incidence in Children Under Seven Years of Age: A Systematic Review and Meta-Analysis.

Oral health is crucial for young children, yet plaque and gingivitis pose significant challenges. This review evaluates oral health interventions for children under seven years to identify effective strategies. A systematic review was conducted across multiple databases using predefined criteria. Thirteen thousand five hundred records were identified, with 13 studies meeting the inclusion criteria. Various interventions were assessed, including tactile models, digital tools, fluoride varnish, and education programs. The meta-analysis showed heterogeneity in outcomes, with some interventions significantly reducing plaque and gingivitis. Tactile models and digital tools demonstrated effectiveness, particularly among children who were visually impaired and had congenital heart defects. However, fluoride varnish showed mixed results. School-based interventions and advanced toothbrushing technologies effectively reduce early childhood caries and plaque. Despite publication bias, a low risk of bias was observed across studies. The findings underscore the importance of tailored interventions and collaboration among stakeholders. Comprehensive oral health education, innovative digital tools, and multifaceted approaches are recommended to promote lifelong oral health habits. Further research is needed to standardize protocols and assess long-term effectiveness. Evidence-based interventions can significantly improve oral health outcomes for children under seven, laying the foundation for lifelong oral health.

Restoration of Anterior Teeth Defect With Porcelain Laminate Veneer Using the Refractory Technique: A Case Report.

Anterior teeth play an important role in the aesthetic appearance of an individual. Hence, restoration of the anterior teeth has always been a significant concern for both dentists and patients worldwide. Indirect restoration using laminate veneers has revolutionized cosmetic dentistry by minimizing tooth preparation compared to full dental crowns. It also enhances vitality, color matching, and superior mechanical properties compared to direct composite restoration. The success of veneer restoration depends on case selection, material choice, and fabrication technique, tailored for every patient based on a thorough consideration of the existing lesion and the needs of the patient. This clinical report exemplifies the conservative treatment of a refractory defect on the labial surface of the maxillary central incisor using a minimal-thickness veneer fabricated from a refractory porcelain system.

Spatial Abilities and Endodontic Access Cavity Preparation: Implications for Dental Education.

INTRODUCTION: Access cavity preparation is a crucial step in root canal treatment but is one of the most complex procedures in the curriculum to learn, with students often reporting spatial orientation difficulties during drilling. The present study aimed to evaluate the influence of spatial abilities on the preparation of endodontic access cavities among third-year dental students. MATERIALS AND METHODS: Students from Lyon dental faculty participated voluntarily. The mental rotation test (MRT) evaluated spatial ability. Students prepared access cavities on 3D-printed mandibular molars, subsequently scanned and assessed against eight evaluation points, including morphology, canal access, floor preservation and convergence angle. Principal component analysis (PCA) assessed dataset variations. RESULTS: A total of 43 volunteers participated. PCA revealed two principal components accounting for 80.8% of variations: the first PC primarily consisted of MRT score (64.3%) and morphology (14.1%); the second comprised operative time (46.1%) and morphology (18.0%). There were significant differences in morphology based on MRT scores, but no correlation was found between other parameters. DISCUSSION: Lower MRT scores were associated with larger cavity preparations, raising questions about potential curriculum adaptations to enhance spatial reasoning. The operative time was not correlated with higher MRT scores but did contribute to variations in cavity morphology. CONCLUSION: Spatial abilities have a substantial impact on the quality of endodontic access cavity preparations; further studies should evaluate if the incorporation of 3D atlas exercises could be beneficial.

A case of obstructive chronic bacterial sialadenitis of submandibular salivary gland.

A young man in his early 20s presented with extraoral swelling on left side of his face, which had been present for a period of 1 month. Intraoral examination revealed an erythematous swelling on the left side of floor of the mouth at the ductal opening of left submandibular salivary gland. On palpation, multiple firm masses were noted, and pus mixed with blood was discharged from the ductal opening. He reported a history of swelling occurring in the same region, which was associated with mild fever and subsided after taking antibiotics. Keeping the history in mind, multiple radiographical investigations were carried out, focusing on the submandibular salivary gland. These investigations revealed the presence of salivary calculi, also known as salivary stones or sialolith, in the ductal pathway, causing obstruction to the glandular parenchyma. Hence, a final diagnosis of obstructive chronic bacterial sialadenitis was made. The case was treated surgically due to the size of the salivary stones, in combination with a preoperative antibiotic course. Multiple stones were retrieved and the incision was sutured. Complete healing was noted in a span of 2 weeks. This case report highlights the effectiveness of conventional imaging modalities in early diagnosis compared with advanced imaging techniques. By using conventional imaging, the case was managed with a simple surgical procedure rather than the more invasive option of removing the entire gland, thereby preserving the patient's quality of life. This case report underscores the importance of clinical examination and selecting appropriate investigative tools for early diagnosis, supported by a comprehensive literature review.

Does enamel deproteinisation with 10% papain affect shear bond strength of orthodontic adhesives: a randomised controlled trial.

OBJECTIVE: To evaluate the effect of 10% papain as an enamel deproteinising agent on the shear bond strength (SBS) of three orthodontic adhesives: Transbond XT, resin-modified glass ionomer cement (RMGIC) and Biofix. DESIGN: Single-centre, double-blinded, split-mouth randomised controlled trial. SETTING: Department of Orthodontics and Dentofacial Orthopaedics, Nair Hospital Dental College, Mumbai, India. PARTICIPANTS: A total of 20 participants requiring bilateral premolar extraction for fixed orthodontic treatment in both the maxillary and mandibular arches were included in this study. METHODS: In total, 80 premolars from the above-mentioned participants were divided into four groups as follows: group A: Transbond XT deproteinised with 10% papain gel; group B: Biofix deproteinised with 10% papain gel; group C: RMGIC deproteinised with 10% papain gel; and group D: Transbond XT without enamel deproteinisation as a control group-bonded as instructed by the manufacturer. After deproteinisation, brackets were bonded and after a follow-up period of 28 days, the teeth were extracted. The SBS was then measured using the Universal Testing Machine. The force needed to shear the bracket was documented, and bond strengths were subsequently calculated in megapascals (MPa). The obtained results were subjected to statistical analysis and one-way ANOVA was performed to compare the mean SBS between the groups. Subsequently, pairwise comparisons were conducted using Tukey's post hoc test. RESULTS: There was a statistically significant difference in SBS among all groups (P = 0.002). The SBS of TransXT with deproteinisation increased significantly compared with TransXT without deproteinisation (P = 0.03). There was no statistically significant difference between the SBS of TransXT without deproteinisation and RMGIC (P = 0.47) and Biofix (P = 0.39), both with deproteinisation. CONCLUSION: The use of 10% papain for deproteinising enamel improved the SBS of all materials. Deproteinising improved the SBS of RMGIC and Biofix to the level of TransXT without deproteinisation.

Dentists' knowledge, attitudes, and awareness regarding interprofessional collaboration with physical therapists.

PURPOSE: Interprofessional collaboration (IPC) between dentists and physical therapists (PT) could improve access to patient treatment and oral care outcomes. This study aimed to assess dentists' knowledge, attitudes, and awareness of IPC with PT. METHODS: The study design included a 16-question online survey sent to dentists (n = 102) at a university in fall 2022 via SurveyMonkey. This survey evaluated dentists' knowledge of PT services and IPC referrals, awareness of PT IPC improving oral health and continuing education (CE) opportunities, and attitudes toward team care. Statistical analysis was performed using Mann-Whitney U, Kruskal-Wallis, and Chi-squared tests. RESULTS: Participants included general dentists (71.2%) and dental specialists (28.8%), with experience ranging from 1-5 years through 55+ years. Gender distribution included approximately 46.2% female and 53.8% male, with a survey response rate of 51.0% (n = 52). Females reported a significantly higher interest in PT IPC (p = 0.016) and referring (p = 0.022) than males. Dentists in practice for 21-40 years reported significantly higher participation in CE referral courses compared to other groups (p = 0.011). Compared to dental specialists, general dentists had a significantly more positive attitude when asked if dental collaboration with PT and physicians is equally important (p = 0.001). Additionally, 78.8% of respondents reported interest in attending a CE course on interprofessional education. CONCLUSIONS: This study demonstrated dentists' limited awareness of the PT interprofessional collaborative approach. Females and general dentists reported higher positive attitudes toward PT IPC relationships. Most dentists were interested in attending additional IPC training.
