OBJECTIVE: The objective of this epidemiological study was to assess the prevalence and severity of temporomandibular disorders (TMD) in undergraduate students at CMH Lahore Medical College (CMH-LMC) and Institute of Dentistry (IOD) using Fonseca’s questionnaire. METHODOLOGY: A cross-sectional survey study was conducted. A questionnaire was distributed among 644 undergraduate students attending CMH Lahore Medical College (CMH-LMC) and Institute of Dentistry (IOD). The questionnaire had some general questions regarding medical and dental history requiring responses in yes or no and it had 10 specific questions regarding the temporomandibular joint with response options yes, sometimes & no which were allocated scores 10, 5 and 0 respectively. The sum of points was used to classify participants into TMD free, mild, moderate, and severe temporomandibular disorders (TMD). RESULTS: The prevalence of TMD was found to be 62%. Among all the participants almost 37% were TMD free, 43% students suffered from Mild TMD, 18% students had moderate TMD and 1% students suffered from severe TMD. CONCLUSION: The Fonseca’s questionnaire can be used as an effective tool in assessment of prevalence and severity of temporomandibular disorders. Public health services should adopt the questionnaire for screening, as information can be obtained in a relatively short period and at a low cost for a wide population. KEYWORDS: Fonseca’s questionnaire, Temporomandibular disorders, Orofacial pain, Cervicofacial muscles.
Background: Papacarie pre-treatment of dentin surface has been reported to exhibit good bond strength values between dentin and composites. Its desirable properties like high pH, sites specify and anti-inflammatory response makes it a future material in place acid etching pre-treatment. Acid etching may cause sensitivity and collapse of dentinal matrix. Methods: This in-vitro study involved, 60 caries free extracted premolars, randomly divided into three groups. Control Group (Group A) No pre-treatment of dentin prior adhesive application. Experimental Group B acid etchant was applied before adhesive application. Experimental Group C Papacarie was used as a pre-treatment agent. All these specimens were tested for shear bond strength with the help of Universal Testing Machine. All the collected data was entered in SPSS version 20.0. ANOVA was used to determine the mean SBS (Shear Bond strength) values of control and experimental groups. Results The mean shear bond strength of material was 7.74±0.47 in group A, 17.80±1.43 in group B and 15.11±0.70 in group C. Group B showing better strength than other two groups. Conclusion: The study provides information about longevity of composite restorations and may help in extending the clinical usage of papacarie to avoid harmful effects of acid etching on dentin and pulpal tissue.
Objective: The object of this survey study was to assess the knowledge, attitude and practice of dentists towards resin bonded bridges across Pakistan. Methodology: A cross-sectional survey study was conducted. A self-administered questionnaire was distributed among 500 dentists across Pakistan as a google form through electronic media. The questionnaire had three sections. First two sections had details about purpose of study and demographic details respectively. In the third section knowledge, attitude and practice of the participants were assessed. Knowledge and attitude were scored. Level of knowledge and attitude towards use of RBBs was correlated with other variables. Significance of factors related to RBB success was evaluated as percentages. Results: A total of 162 males (78%) and 128 females (63.1%) had adequate knowledge. Overall, 303 (75.2%) participants were inclined to use the RBB while only 100 (24.8%) were not in the favor of using this treatment. 286 participants (71%) were confident to offer this treatment to their patients however, 85% of them actually employed RBBs for ≤ 20% of their tooth replacements. Lack of skills was considered as a major hindrance to employ RBB treatment followed by the lack of technical support. Conclusion: The results of the study showed that participants are poised in knowledge regarding RBBs but they are reluctant to use this confidently because of lack of practical skills. Modest use of RBB in clinical practice is a question mark and a food for thought. Keywords: Resin Bonded Bridges, Conservative Dentistry, Minimally Invasive Dentistry.
The use of modern technology infrastructure is regarded as critical for the successful adoption of innovative teaching approaches. Objective: To determine the attitudes and concerns of medical and dental faculty about the use of E-learning as a medium of instruction during the Covid-19 outbreak. Methods: This cross-sectional study included 368 faculty members from Medical and Dental Colleges of Punjab province was conducted utilizing a questionnaire developed following a thorough literature review and analysis of questionnaires from previous studies. A 5-point Likert scale was used to record knowledge, attitude, and practice, and the questionnaires were graded. SPSS version 22 was used to enter the data. The mean and SD of quantitative variables such as age and total score for knowledge, attitude, and practice score was calculated. Gender, education level, knowledge, attitude, and practice were all represented as frequency (%). Results: Zoom was shown to be the most commonly utilized software (69.0%). E-learning was deemed a beneficial tool in medical education by 56% of the respondents. An equal percentage of individuals (35%) agreed and disapproved the use of E-learning approaches over traditional ones. Only 30% participants resisted the change from traditional educational methods. Technological infrastructure was considered crucial for successful implementation of E-learning by 46% of the participants. Conclusion: Faculty members are using the available infrastructure to implement E-learning teaching modalities to the best of their knowledge and abilities.
A better understanding of the Science of Dental materials as a subject depends upon theoretical knowledge and its clinical application. The multitude of teaching methodologies in the dental curriculum has been incorporated to determine learning outcomes. Objective: This study aimed to found the perception of BDS second-year students toward the subject of dental materials and evaluate the difficulty in learning and acquisition of concepts in this preclinical year. Methods: This cross sectional study was conducted among 130 students of BDS second year registered with University of Health Sciences, Lahore. Pre-designed questionnaire was used as research tool to determine the students’ perceptions towards teaching methodologies and understanding of dental Materials. Results: Only 53.7% of the students reported DM as an interesting subject. Satisfaction with content was 90% and delivery and pace of the lectures were reported at 79.3%. Majority of the student (86.8%) reported lecture materials easy to understand. The most useful method for learning and understanding this subject is group discussion 76.15%, followed by PowerPoint presentation 73.85%. The favored mode of assessment was MCQs (80%) followed by practical lab 66.93%. To improve learning 82.3% of the students recommended group discussion and integrated teaching method (77.6%). Conclusions: The majority of students found Dental material a difficult subject. A better understanding of this subject needs improvement in already applied teaching methodologies with an integrated teaching mode
