Objectives The aim of this study was to investigate the current knowledge and attitude of deep caries removal method among dental students in Malaysia. Materials and Methods A total of 303 students (n = 303) responded to the online questionnaire. The first part of questionnaire was to evaluate the demographic data of the respondents and focused on the technique and management approach used for deep caries lesion. The second part investigated the preferred treatment used for deep caries based on the designated clinical case, while the third part assessed the factors that affected the decision on deep caries management. Statistical Analysis Independent t-test was used to compare difference between the two groups. Results Seventy four percent of the students have the knowledge of the different methods of caries removal, while 25.8% were only familiar with complete caries removal. The preferred method for deep caries removal in permanent teeth was partial caries removal (53%). For primary dentition, 45.6% of the students prefer to perform pulpotomy as compared with other techniques. There was no significant difference in caries removal method for permanent teeth between undergraduate year of study (p > 0.05), which was partial caries removal at 52.7 and 53.5%, respectively. For primary dentition, the preferred caries removal method was pulpotomy for year 4 (39.8%) and year 5 (52%) students. The popular material to restore deep caries was resin composite (42%) followed by glass ionomer cement (23.3%). Conclusions This study showed that partial caries removal was the preferred method despite partial understanding on the identification of the clinical indicators of the technique.

Introduction: This is a clinical case of a healthy woman with a missing upper right central incisor (#8) who requested a permanent prosthetic replacement due to endodontic failure. Clinically, she was presented with thin edentulous ridges and fibrous gingival tissue and minimal or compromised alveolar bone segment on the buccal profile as detected on cone-beam computed tomography (CBCT). Case Report: The conventional treatment approach is to add pink porcelain; however, rarely does the prosthetic gingiva substitute blend well with the existing oral profile. Therefore,Guided Bone Regeneration (GBR) was done instead on #8 using the allograft [RegenOss, Neobiotech] and PTFE membrane. Upon examination, membrane exposure was detected, and the size was found to be increased in follow-up visits. The membrane was replaced with a Concentrated Growth Factor [CGF] and sutured at the site of the defect. After 12 months, a vertical and horizontal bone with adequate soft tissue emergence profile was achieved clinically, radiographically, and digitally. The delayed removal of the exposed membrane provided more time for initial bone regeneration in GBR. The replacement barrier of an exposed membrane using CGF is considered an innovative procedure with the cellular content providing vascularization and regeneration. Conclusion: This case concludes that CGF can be a viable alternative material to enhance GBR outcome in replacing exposed membranes.

Journal of Clinical and Diagnostic Research aims to publish findings of doctors at grass root level and post graduate students, so that all unique medical experiences are recorded in literature.

Introduction: Undergraduate (UG) dental students are trained for fixed prosthodontics course clinically in teaching institutions during the clinical years. However, there is a lack of objective data on the quality of fixed prostheses preparations done by UG students on their patients for academic and clinical staff. Aim: To evaluate the full-coverage crown preparations performed by UG dental students in the university clinical teaching programme. Materials and Methods: This study was a clinical audit done in the Faculty of Dentistry, Universiti Sains Islam, Malaysia (USIM) from April to July 2018. The demographic and clinical data were collected from the patients’ notes and included relevant information of patients such as age, gender and others. Full-coverage crowns were analysed and crown preparation assessments were done using specific criteria and standards. The descriptive data were measured in frequency and percentage for categorical variables and mean and standard deviation for continuous data. Results: A total of 31 patients fitted with 45 units of full-coverage crowns were analysed. The mean age of patients treated by fifth year dental students was 40.5 (±14.16) years. A 51% Porcelain Fused to Metal (PFM) crown provided to the patients. On the whole, UG undergoing the dentistry programme in the institution scored the lowest (51%) on proximal reduction and the highest (97.7%) on producing smooth and continuous preparation. Conclusion: Majority of the crowns prepared by students have acceptable preparation except in proximal reduction and cervical margin preparation that can be improved upon and emphasised further during the teaching and learning sessions.
