Introduction: A few studies investigated the numerous potential endodontic uses of CBCT, including the examination of root canal morphology and presumed that CBCT was effective for the initial identification of such morphology; moreover CBCT is a reliable method for the detection of the MB2 canal when compared with the gold standard of physical sectioning of the specimen. The aim of this study was to identify the root and canal morphology of the maxillary first molars among Malaysians analysed by cone-beam computed tomography (CBCT) images. Materials and Methods: Maxillary first (n = 421) molars from Malaysian patients (n = 241) of Malay, Chinese and Indians inceptions were examined by two Endodontists using in vivo CBCT methods. The number and configuration of roots, the number of root canals, and the canal configuration according to Vertucci’s classification were determined. Results: Single roots were not found in maxillary first molars. The incidence of fused roots was 1.995% in the first molars between mesiobuccal and distobuccal roots. In (421) 3-rooted maxillary first molars, additional canals were found in 45.6% of the mesiobuccal (MB) roots and 0% of the distobuccal (DB) roots. Bilateral symmetry of the MB roots was found in 82.36% of the first molar. Only one tooth was found to have pulp stone inside the pulp chamber. Conclusions: The root and canal configuration of a Malaysian population showed different features from those of other populations. CBCT scans can enhance the understanding of root canal anatomy, with the potential of improving the outcome of endodontic treatment.

Endodontics procedures are difficult and complicated that most of the practitioners would encounter. Therefore, dental students should gain their confidence and competent during their training. This research aimed to study the perception of final year students on confidence level regarding endodontic treatments from all public universities and their opinions on the quality of endodontic education. A Google Form was used to disseminate an online questionnaire to all dental students from public universities across Malaysia. The survey included both scaled answer and open-ended questions. 184 responses out of 235 students, were obtained (response rate = 78%). Perception of competence and confidence were significantly greater amongst the students from research-based universities group (P < 0.05). 93.5% (n=179) of participants agree that they were confident to do endodontic procedure on anterior tooth, whilst on posterior tooth, only 75.5% (n=139) were confident. Only 6.5 percent of participants (n = 12) did not feel confident doing root canal treatment on single-rooted teeth, but 76.1 percent (n = 140) did not feel competent performing root canal treatment on multirooted teeth. Over 90% of the students rated the quality and the amount of time spent on endodontic education were adequate at their respective university as ?5 on a Likert scale (1 = inadequate to 10 = adequate). In addition, when they were asked to give the suggestion on how to improve the quality of endodontic education, 10.9% of the students suggested to increase the number of practical session and to do regular discussion regarding endodontic cases. It is vital to improve undergraduate endodontic education in order to raise students' perceptions of their confidence and competence when doing root canal therapy.

ABSTRACT Introduction: Dental officers could be the first medical personal to diagnose HIV/AIDS and cross–contamination may happen. More efforts should be taken to improve knowledge and the behaviour of dental students towards HIV/AIDS patients. The objective of this study is to assess and compare knowledge and the attitude of USIM dental students towards HIV patients. Methods: A total of 136 dental students from Year 2 to Year 5 of academic year 2017/2018 participated in this study. Students were consented and briefed about the purpose of the current project prior to answering self-administered questionnaires that have been previously validated. Results: The mean total knowledge and attitude score were 69.65% (good) and 68.54(%) (passive), respectively. Both clinical and pre-clinical students have passive attitude towards HIV patients and showed good level of knowledge with 70.81% and 66.39% respectively. There were significant association between sex and knowledge of HIV/AIDS among USIM dental students (p=0.001). There is also a statistically positive weak correlation between knowledge and attitude towards HIV/AIDS patients. Conclusion: USIM dental undergraduates have good knowledge and passive attitude towards HIV/AIDS patients. Improvement of dental curriculum regarding HIV/AIDS knowledge and attitude towards HIV/AIDS patients is recommended through conducting activities such as seminar, workshop and small-group discussion among dental students.

Introduction: Cervical restorations were known as the least durable type of restoration. Therefore, it is important for clinician to identify the contributing factors that may lead to failure of the restorations. Objective: The purpose of this study was to compare the clinical performance in terms of type of restorative materials and the influence of clinical handling technique of non-carious cervical restorations. Materials and Methods: This cross-sectional study was carried out to patients with restorations on non-carious cervical lesions (NCCLs) at Universiti Sains Islam Malaysia dental clinic. The clinical performance of the restorations was evaluated using the ratings of the United States Public Health Service criteria and analyzed using the Pearson Chi-square. Results: A total of 121 restorations from 34 patients were evaluated by one investigator. Between three restorative materials used which are glass ionomer cements (GIC), RC, and resin-modified GIC (RMGIC), criteria of marginal integrity, marginal discoloration, and anatomic form were not significantly different (P = 0.179, P = 0.134, and P = 0.235, respectively; P < 0.05). In terms of retention and secondary caries, GIC showed statistically significant difference (P = 0.021). The restorations that were evaluated as clinically acceptable showed no significant difference between restorations with and without cavity preparation. Conclusion: Different restorative materials used will affect the longevity of the restorations, but different clinical handling technique does not affect the clinical performances of NCCLs restorations. In this study, the clinical performance of GIC was superior to RC and RMGIC in terms of retention and occurrence of secondary caries but similar in marginal integrity, marginal discoloration, and anatomic form.
