Observational Study
Knowledge and Attitudes regarding Temporomandibular Disorders among Postgraduate Dental Students and Practicing Dentists in Western China: A Questionnaire-Based Observational Investigation.
BACKGROUND
It is necessary for dental students and dentists to apply their temporomandibular disorders (TMDs)-related knowledge to clinical practice. The current study aimed to evaluate the knowledge and awareness of postgraduate dental students and practicing dentists regarding etiology, diagnosis, and treatment of TMD in western China and thus provide suggestions on TMD curricula design to get postgraduate students and dentists better prepared for TMD diagnosis and treatment.
METHODS
This observational and descriptive cross-sectional study was conducted among postgraduate students and practicing dentists in western China. Twenty-five reorganized knowledge questions in four domains were selected from the published literature and were evaluated with answer options from "strongly agree" to "strongly disagree," and "I don't know." "Consensus" is defined as more than 50% of respondents in a group agree or disagree with a statement. Chi-square tests were performed for comparisons between the two groups.
RESULTS
A total of 132 postgraduate dental students and 123 dentists completed the questionnaire. Around 75% of postgraduate students and 85% of dentists claimed that they have never participated in systematic training in TMD. Nine statements in etiology, diagnosis, treatment, and prognosis of TMD had different consensus between the two groups. And the dentist group tended to agree more with 12 statements in the questionnaire.
CONCLUSIONS
The majority of Chinese dentists and dental students have not taken any TMD courses and possess limited knowledge of TMD. Curriculum reform for predoctoral education, postgraduate education, and continuing education is needed to augment knowledge and skills for TMD diagnosis and treatment.

OBJECTIVES
Awareness of the interface between restorative and orthodontic treatments is essential for dentists to facilitate a meaningful interdisciplinary approach by integrating the knowledge and skills of different dental disciplines into patients' treatment to enhance outcomes. The aim of this study was to investigate General Dental Practitioners' (GDPs) awareness of the orthodontic-restorative interface.
METHODS
This was a mixed-method study involving the collection of a) quantitative data via a bespoke online questionnaire and b) qualitative data through open questions. A weblink was created to the questionnaire using Opinio®. The questionnaire was distributed to GDPs practising in the UK. Clinical vignette-based questions assessed GDPs awareness and the results were categorised into two groups: aware and unaware. Two months after the primary survey, respondents were sent an email with follow-up (reliability) survey. Reliability responses were compared against the primary responses to assess the repeatability using intraclass correlation coefficient. Data were analysed using independent t-test and X test.
RESULTS
118 complete responses were received. 63 GDPs (53.4 % [95 % CI 44 %-63 %]) demonstrated a good understanding of the orthodontic-restorative interface. These GDPs were characterised by greater age (t = 2.75, p = 0.007) and experience (t = 3.54, p < 0.001). Qualitative data showed that respondents perceived orthodontic-restorative treatments as minimally invasive and aesthetics enhancing.
CONCLUSIONS
Orthodontic-restorative treatment aids in minimal invasive dentistry. GDPs lack adequate awareness of the orthodontic-restorative interface in relation to patient care and communication with patients. More quality and structured undergraduate and postgraduate training are imperative to facilitate GDPs to understand and utilise aspects of orthodontic-restorative treatments to raise the standard of patient care. Additionally, to support these patients, the educational pathway between GDPs and specialist orthodontists is crucial.
CLINICAL SIGNIFICANCE
GDPs ability to assess and carry out orthodontic-restorative treatments would conserve natural teeth. Dependable access to orthodontic services would encourage GDPs to refer challenging cases to specialists or dentists with enhanced skills. When the circumstances call for it, patients should be given orthodontic-restorative alternatives, regardless of the potential consequences of their acceptance of the procedures.

: To provide safe and effective local anesthesia, dentists must have knowledge of neuroanatomy, anesthesia agents, techniques, equipment, and proper use of local anesthetics. This study aims to explore the knowledge, practices, and confidence regarding local anesthetics and anesthetic techniques in dentistry. : The online cross-sectional questionnaire was conducted via social media, and yielded 441 responses from across the country (69.8% women and 30.2% men; 70.7% general dentists; and 29.3 specialists). The data collected included sociodemographic characteristics, knowledge, and practices pertaining to the usage of local anesthesia. The questionnaire also documents their self-assessed confidence level in applying different local anesthetic techniques and experiences with adverse reactions. The obtained data were processed by description and using a generalized linear model for regression. : The respondents had a median knowledge score of 6 out of a possible 14 points regarding local anesthetics in dental medicine, and their median self-confidence level in the successful application of various techniques of local anesthesia was 54 out of a maximum of 85 points. The results showed that a higher knowledge level was associated with the female gender (OR 1.83, CI 1.13-2.98, = 0.014) and specialization in oral surgery (OR 7.04, CI 1.71-29.07, = 0.007). In contrast, a lack of confidence in using various local anesthetic techniques was also associated with the female gender (OR 0.63, CI 0.41-0.99, = 0.047) and specialization in orthodontics (OR 0.16, CI 0.03-0.88, = 0.035). Of the respondents, 81.4% (n = 371) experienced a local complication, and 42.2% (n = 186) experienced a systemic complication during local anesthesia. The complications experienced cannot be associated with a lack of knowledge or self-confidence ( > 0.05). The majority of respondents (364 of the 441 total-82.5%) expressed interest in receiving further education on the topic of local anesthesia. : The research results show that the dentists involved in the study have poor knowledge of local anesthetics and moderate self-reported confidence levels in using various local anesthetic techniques. Moreover, dentists' self-confidence in applying different techniques of local anesthesia is not related to their knowledge. Therefore, it would be necessary for dentists to undergo a continuing dental education program that enables them to enhance their skills and knowledge in local anesthesia.

BACKGROUND
Strong evidence supports the association between periodontitis and certain systemic diseases. The aim of the present study was to evaluate the knowledge of a group of physicians and dentists in Serbia regarding this topic and assess their professional actions to prevent and control both periodontal and systemic diseases.
METHODS
An anonymous self-administered structured questionnaire was sent to the available e-mail addresses of randomly selected healthcare providers working in Serbia. According to the inclusion criteria, general practitioners, specialists, general dentists, and specialists working in government hospitals and private practices in various cities in Serbia were recruited in the study. The questionnaire consisted of 17 questions divided into three parts. The first part recorded the sociodemographic characteristics of participants, the second part included questions about the clinical manifestation and etiology of periodontitis, as well as knowledge of the association between periodontitis and systemic diseases, and the third part included questions about professional procedures for the prevention and control of periodontitis and systemic diseases.
RESULTS
A total of 1301 health participants, 739 (57.8%) physicians and 562 (43.2%) dentists, were included in this cross-sectional study. Most respondents (94.7%) were aware of the association between periodontitis and general health. The highest percentage of respondents associated diabetes mellitus and periodontitis. Factors significantly associated with higher knowledge were female sex (odds ratio [OR], 1.86; 95% confidence interval [CI], 1.37-2.52; p < 0.001) and dental profession (OR, 5.86; 95% CI], 4.03-8.53; p < 0.001). Participants who had higher knowledge score were more likely to ask their patients about gum/systematic health (p < 0.001) and refer them to dentists/physicians (p < 0.001).
CONCLUSIONS
It was concluded that compared to the group of dentists, the group of physicians had less knowledge of the relationship between periodontitis and systemic diseases. The female gender was significantly associated with better knowledge. A better understanding of this topic is associated with better clinical practice.

BACKGROUND
Continuing professional development (CPD) activities relevant to medical doctors and their patients should be informed by current assessed training needs. The CPD provision is expected to improve the quality of professional practice and ethics. However, the Uganda Medical and Dental Practitioners' Council still receives about 40 reports of malpractice every month.
AIM
The study aimed to describe the CPD training needs of doctors working in public primary care facilities in central Uganda.
SETTING
The district health system of central Uganda comprised 10 General Hospitals (GH) and 37 Health Center IVs (HC IVs) with a staffing norm of six and two doctors, respectively.
METHODS
This was a cross-sectional survey of 100 doctors working in public primary care facilities using the World Health Organization (WHO) Hennessy-Hicks questionnaire. Descriptive statistics of the importance, current performance, and training need of each skilled activity were calculated. Content analysis was applied to data from the open-ended questions.
RESULTS
The response rate was 91%, majority were males, 80 (87.9%) from 7 GHs and 24 HC IVs with an average age of 37.9 years. The domain with the highest CPD training need for the doctors was research and audit, with a mean score (standard deviation [s.d.]) of 1.94 (±1.69), followed by administration 1.58 (±1.61) and clinical tasks 1.28 (±1.29). The clinical tasks domain had the most suggested CPD topics.
CONCLUSION
Research and audit and clinical tasks were identified as important domains for CPD training for doctors in this setting.Contribution: The results give insight into CPD training needs of primary care doctors and guide various CPD providers.

AIM
Root canal treatment procedures are considered "the bread and butter" for routine clinical practice. Although retreatments have been primarily performed by endodontists (ENs), many senior practitioners and dentists who are root canal enthusiasts do opt for undertaking endodontic retreatment procedures. This survey helps us understand the practice trends and attitude of dentists undertaking endodontic retreatment procedures in and around Mumbai city.
MATERIALS AND METHODS
Questionnaires pertaining to endodontic retreatment were randomly distributed (hard copy/soft copy) to 1000 practicing dentists in and around Mumbai city. The questionnaire survey was divided into Part A: involving basic details such as name, demographic information, and clinical experience of the dentist and Part B: a set of questions based on assessing the trends, techniques, materials, and opinions of dentists regarding endodontic retreatment. Only those dentists who treated endodontic retreatment patients were asked to fill the Part B form. A response rate of 60.2% was achieved.
RESULTS
Out of total 602 participants, 49% of dentists (295) reported to undertake endodontic retreatment cases. Among the 295 respondents, 46.11% were Endodontists (ENs) while 53.8% were BDS or MDS of other specialties (ODs). Most dentists preferred multi-visit retreatment and prescribed antibiotics only in specific cases. Radiovisiography was the most preferred imaging aid. Calcium hydroxide and 3% sodium hypochlorite were favored choices for intracanal medicament and irrigant, respectively. Cold lateral compaction obturation technique was most common. Advanced equipment such as microscopes, loupes, ultrasonics, retreatment files, and thermoplastic obturations were more prevalent among ENs as compared to ODs.
CONCLUSION
This study found some differences in endodontic retreatment practice trends among ENs and other dentists. But overall, most clinicians followed the international norms and are updated in recent advances in materials and techniques used in endodontic retreatment.

Review
OBJECTIVES
Dental practice is based upon dentists' cognitions, knowledge being foundational. Knowledge is attained through education and perception. Although knowledge is modulated by beliefs, attitudes, preferences, and behaviors, it is essential to evidence-based practice. Cross-sectional studies uniformly demonstrate that community NSRCT is of sub-optimal quality worldwide, is lack of knowledge a problem? Our purpose was to measure dentists' knowledge of root canal treatment (NSRCT).
DATA
Quantitative and qualitative data were extracted: purpose, topics assessed, authors cited knowledge sources, number of dentists studied, number of questions, authors descriptors of knowledge level,% correct answers by question, authors recommendations.
SOURCES
OVID Medline, EMBASE, Web of Science, and hand-searching.
STUDY SELECTION
Studies which had measured dentists' knowledge of non-surgical root canal treatment that was valuable, reliable, and had practical implications which could be implemented. A total of 51 papers from 19 countries measured the knowledge of 15,580 dentists using 445 questions on 29 root canal treatment topics.
CONCLUSIONS
'Gold standards' were from literature, external bodies, or expert consensus in 47, 31, and 2 papers respectively. Levels of knowledge by percentage correct answers among studies were poor to moderate and varied considerably. The mean, for the 50 studies where overall study percentages could be calculated, was 57 %, standard deviation 17 %, and a range of 16 % to 82 %. Authors' adjectives describing knowledge levels were generally negative. Additional education was advised in 49 papers, but without evidence that education was inadequate; 6 papers recommended increased use of protocols; only 5 papers advocated research on the cause of lack of knowledge.
CLINICAL SIGNIFICANCE
Dentists' root canal treatment knowledge was found to be poor to moderate, as well variable. This may constrain quality of care. However, provision of information without attention to dentists' cognitions and motivations may not be successful. Educational strategies and goals should be re-evaluated. Evidence-based practice faces many barriers.

BACKGROUND
As highlighted by the recent World Health Organization Oral Health Resolution, there is an urgent need to better integrate primary and oral health care. Despite evidence and guidelines substantiating the relevance of integrating type 2 diabetes mellitus (T2DM) and periodontitis care, the fragmentation of primary and oral health care persists.
OBJECTIVE
This paper reports on the evaluation of a prototype digital decision support system (DSS) that was developed to enhance the integration of T2DM and periodontitis care.
METHODS
The effects of the prototype DSS were assessed in web-based simulated environments, using 2 different sets of case vignettes in combination with evaluation surveys among 202 general dental practitioners (GDPs) and 206 general practitioners (GPs). Each participant evaluated 3 vignettes, one of which, chosen at random, was assisted by the DSS. Logistic regression analyses were conducted at the participant and case levels.
RESULTS
Under DSS assistance, GPs had 8.3 (95% CI 4.32-16.03) times higher odds of recommending a GDP visit. There was no significant impact of DSS assistance on GP advice about common risk factors for T2DM and periodontal disease. GDPs had 4.3 (95% CI 2.08-9.04) times higher odds of recommending a GP visit, 1.6 (95% CI 1.03-2.33) times higher odds of giving advice on disease correlations, and 3.2 (95% CI 1.63-6.35) times higher odds of asking patients about their glycated hemoglobin value.
CONCLUSIONS
The findings of this study provide a proof of concept for a digital DSS to integrate T2DM and periodontal care. Future updating and testing is warranted to continuously enhance the functionalities of the DSS in terms of interoperability with various types of data sources and diagnostic devices; incorporation of other (oral) health dimensions; application in various settings, including via telemedicine; and further customization of end-user interfaces.

Hypodontia is a relatively common condition and patients will be seen by both general dental practitioners and specialist dental colleagues. Although hypodontia can be described as mild, moderate and severe, this does not directly correlate with the complexity of treatment required to provide an acceptable outcome. In addition, the complexity of treatment provided by one colleague in the multidisciplinary team may not be the same as for other colleagues.When treatment planning and delivering dental care for these patients, especially those with severe hypodontia, it is useful to recognise the factors that make their care complex and also to follow principles for multidisciplinary treatment planning.

OBJECTIVES
Given the increasing incidence of oral cancer, it is essential to provide high-risk communities, especially in remote regions, with an affordable, user-friendly tool for visual lesion diagnosis. This proof-of-concept study explored the utility and feasibility of a smartphone application that can photograph and diagnose oral lesions.
METHODS
The images of oral lesions with confirmed diagnoses were sourced from oral and maxillofacial textbooks. In total, 342 images were extracted, encompassing lesions from various regions of the oral cavity such as the gingiva, palate, and labial mucosa. The lesions were segregated into three categories: Class 1 represented non-neoplastic lesions, Class 2 included benign neoplasms, and Class 3 contained premalignant/malignant lesions. The images were analysed using MobileNetV3 and EfficientNetV2 models, with the process producing an accuracy curve, confusion matrix, and receiver operating characteristic (ROC) curve.
RESULTS
The EfficientNetV2 model showed a steep increase in validation accuracy early in the iterations, plateauing at a score of 0.71. According to the confusion matrix, this model's testing accuracy for diagnosing non-neoplastic and premalignant/malignant lesions was 64% and 80% respectively. Conversely, the MobileNetV3 model exhibited a more gradual increase, reaching a plateau at a validation accuracy of 0.70. The MobileNetV3 model's testing accuracy for diagnosing non-neoplastic and premalignant/malignant lesions, according to the confusion matrix, was 64% and 82% respectively.
CONCLUSIONS
Our proof-of-concept study effectively demonstrated the potential accuracy of AI software in distinguishing malignant lesions. This could play a vital role in remote screenings for populations with limited access to dental practitioners. However, the discrepancies between the classification of images and the results of "non-malignant lesions" calls for further refinement of the models and the classification system used.
CLINICAL SIGNIFICANCE
The findings of this study indicate that AI software has the potential to aid in the identification or screening of malignant oral lesions. Further improvements are required to enhance accuracy in classifying non-malignant lesions.
