OBJECTIVE: With the advances in technology the teaching process needs to be improved. Video assisted learning has become an integral part of effective teaching. Using procedural or instructional videos have shown to augment student's preparedness for real life clinical practice and helps them to improve their skills at their own pace and learning ability. The aim if this study was to assess the impact of procedure-specific video demonstrations on the performance of pre-clinical dentistry students. METHODOLOGY: It was a cross-sectional experimental study conducted at the Pre-Clinical Operative Dentistry Phantom Lab at Bahria University Medical and Dental College Karachi, Pakistan. 50 students were divided equally into group A and group B (25 students in each group) by convenience sampling. Both groups prepared class 1 cavity and restored with amalgam. Group A were taught by a hands-on demonstration whereas Group B were taught by live demonstration as well as a procedurespecific video. The students were analyzed for the quality of their practical work as well as their understanding of key concepts. IBM statistics version 20 was used to carry out the statistical analysis. Pearson Chi Square test and independent T test were used, a p-value less than 0.05 was considered significant. RESULTS: Group A's assessment regarding cavity preparation showed that majority students of the group (n=11) required crucial changes in cavity design. For group B most students (n=9) reproduced important factors of cavity design however improvement was required. For amalgam filling, Group A and B's majority students had similar results. t-test was conducted and significant difference was found in the overall performance scores for group A (M=6.7, SD=1.7) and group B (M=8.0, SD=2.3); t-test p=0.04. CONCLUSION: This study suggests that video assisted learning as an additional tool to traditional teaching, can augment understanding and learning process of students.
The aim of this study was to collect information from dentists regarding treatment of endodontic emergencies and investigate their antibiotic prescribing habits. METHODOLOGY: A cross sectional study was conducted in which questionnaires were distributed to 300 dentists of dental hospitals and private clinics of Karachi, Pakistan. The survey dealt with questions focusing on treatment approaches for different endodontic emergency situations and antibiotic prescribing habits of the dentists. RESULTS: A total of 182 participants were included with a response rate of 65%. In cases of a vital teeth with irreversible pulpitis, (59.9%) of dentists opted for two visit root canal treatment. Dentists with working experience 5 years performed root canal treatment in more than two visits which is in a higher ratio than the other groups (P<0.05). (75.3%) of dentists prescribed medications if RCT required multiple visits. (33.5%) managed emergency case of pulpitis by pulpectomy in combination with analgesics and antibiotics. In management of acute apical periodontitis, (28%) opted for pulpectomy with intra-canal medication. In case of acute apical abscess, (67.6%) of the dentists preferred drainage of the abscess by opening pulp chamber in combination with antibiotics. Most frequently prescribed antibiotics were Amoxicillin-Clavulanate (78.8%). CONCLUSIONS: Dentists were over prescribing antibiotics in may conditions. Educational programs should be conducted on regular basis to increase the knowledge of the dentists.
The objective of this study was to assess awareness of dental practitioners of Karachi regarding minimally invasive dentistry. Study design and Setting: It was a cross sectional study based on questionnaire, conducted in 6 different dental hospitals of Karachi. The sample included dentists who were actively practicing clinical dentistry in Karachi. Specialists were excluded from the study Methodology: A study questionnaire was distributed to the participants which comprised of demographic details, professional data and Likert-Scale based questions to asses respondent’s agreement level related to caries activity, assessment, detection and treatment. Results: Out of the 151 questionnaires distributed, 119 were analysed with an overall response rate of 78.8%. From the total 67.2% dentists were received training in MID through some means in which 36% received training in MID by lectures and clinical training both while 32.8% had no training in MID. MID techniques like ART and sandwich technique was found to be effective by 65% and 50.4% respectively. The 58.8% participants were agreed that caries risk assessment (CRA) should be done in every patient and 55.5% dentists were agreed that restoration should be planned according to patient’s assessment Conclusion: General Dental Practioners were not completely aware of the concepts and application of minimally invasive procedures and had little knowledge regarding caries detection methods and lacked in implementation of MID techniques in their daily practice
