Effectiveness of error-based active learning compared to conventional lecture-based method among undergraduate dental students: A randomized controlled trial.

INTRODUCTION: Dental education assumes an indispensable role in adequately equipping students for a successful career in dentistry. Error-based active learning, an innovative approach in dental education, is a combination of mistake-driven learning (MDL) and case-based learning (CBL) to provide a transformative learning atmosphere for students. While active learning has gained popularity in dental education, the effectiveness of error-based active learning remains unexplored. This study aims to evaluate the effectiveness of error-based active learning among final-year dental undergraduate students in comparison with the conventional lecture-based approach. MATERIALS AND METHODS: A parallel-arm single-blind randomized controlled trial was conducted in a dental institute in India from November 2022 to December 2022. A total of 74 students were randomly allocated to two groups: Group A (n = 37) received error-based active learning and group B (n = 37) received conventional lecture-based learning approach. Atraumatic restorative treatment (ART) was chosen as the topic for the study. The knowledge of students was assessed at three intervals: baseline, post-intervention, and 4 weeks after the intervention, using a self-designed and validated questionnaire with Cronbach's alpha of 0.87 and a content validity ratio of 0.84. A standard survey questionnaire was employed to evaluate students' perceptions of the teaching methods. RESULTS: Error-based active learning group outperformed the lecture-based group significantly in the post-intervention test (20.92 ± 1.42 vs 16.97 ± 3.06), with better knowledge retention (18.30 ± 2.02 vs 14.05 ± 4.26) and positive feedback from the students. CONCLUSIONS: The error-based active learning approach proved superior to the conventional lecture-based method in enhancing and retaining knowledge regarding ART.

Assessment of potential antimicrobial activity of Ocimum basilicum extract and chlorhexidine against Socransky's complex pathogens of oral cavity: An in vitro study.

Background and Objective: Periodontitis is a multifactorial disease initiated by periodontal pathogens and progresses further in destruction of periodontium. Hence, the objective of this study was to test the efficacy of Ocimum basilicum seeds extract on periodontal pathogens. Materials and Methods: O. basilicum seeds were authenticated from a recognized taxonomist. They were coarsely powdered; ethanol-based extract preparation was done by the Soxhlet method and aqueous-based extract by hot infusion procedure. Extracts so obtained were assessed for minimum inhibitory concentration, minimum bactericidal concentration, zone of inhibition, and time-kill assay of O. basilicum seeds extract on periodontal pathogens, and comparatively evaluated the effectiveness against 0.12% chlorhexidine (CHX) gluconate in triplicates. Kruskal-Wallis Test was employed wherein the statistical significance was set at P ≤ 0.05. Results: The concentration of O. basilicum ethanolic extract against periodontal pathogens was determined to be 10 mg/ml, whereas 4.7 mg/ml of aqueous extract was proven effective against periodontal pathogens. Similarly, aqueous extract of O. basilicum developed a wider zone against periodontal pathogens compared to ethanol-based O. basilicum extract. Statistically significant difference found in the effectiveness between both extract and CHX. Conclusion: The antibacterial activity was evident in both the extracts of O. basilicum against anaerobic periodontal pathogens. However, it was more pronounced in aqueous extract, but lower compared to CHX.

Pediatric Dental Fluorosis and Its Correlation with Dental Caries and Oral-Health-Related Quality of Life: A Descriptive Cross-Sectional Study among Preschool Children Living in Belagavi.

AIM: This study aims to assess the prevalence of dental fluorosis and its association with dental caries, oral health behaviors, oral-health-related quality of life and parents' perceptions among preschool children in the 3-5-year-old preschool children living in the Belagavi district of Karnataka, a non-endemic fluorosis region. METHODS: A descriptive cross-sectional questionnaire-based study was conducted among 1200 individuals of the preschool population from 48 government-sponsored child-care development centers in Belagavi, Karnataka, over a three-month period. They were examined following the Dean's fluorosis index (1942) and dmft (decayed, missed, and filled) scores of the participants were also recorded. Parents' perception of oral health was assessed using the self-administered Early Childhood Oral Health Impact Scale (ECOHIS). SPSS software (version 20) was used for statistical analysis. Chi-square test computed categorical data. One-way ANOVA test was used for multiple group comparisons. p < 0.05 was considered statistically significant. RESULTS: Of the 1200 children examined, 10 (0.83%) children exhibited dental fluorosis. Of the 10 children having fluorosis, six had fluorosis present on two or more of their primary teeth, and four had fluorosis on four or more teeth. The mean dmft score was 3.01 ± 1.38 to 3.60 ± 1.72 in 3-5-year-old children, respectively, with statistical significance difference (p < 0.001). The mean score of oral health-related quality of life was 10.74 ± 2.06, which was significantly correlated to the child's age and parents' education level (p < 0.05). CONCLUSION: The study shows a negligible amount of prevalence of dental fluorosis in the non-endemic fluorosis residential district. It also elucidates that children from lower and lower-middle socioeconomic status are more prone to suffer from dental fluorosis as compared to other groups. The mean score of ECOHIS increased proportionally with the caries experience, indicating a significant relationship between the dmft and ECOHIS score. Deciduous dentition fluorosis is often neglected, especially in areas that are not considered endemic for fluorosis and with only optimum fluoride levels in their groundwater, which supports the disease's nature as multi-factorial and shows that a broader perspective is of prime importance to assess, diagnose, and prevent dental fluorosis among the preschoolers, thereby appraising their overall health and hygiene status.

Interest of Oral and Maxillofacial Surgeons Towards Specialised Training in Facial Aesthetic and Plastic Surgery in India - An Evaluative Study.

Introduction: The Dental Council of India has included facial plastic surgery in the scope of practice of Oral and Maxillofacial Surgeons (OMFSs) in India. However, the knowledge and interests of these specialists towards facial plastic surgery are unexplored. Materials and Methods: A descriptive cross-sectional study consisting of a structured questionnaire tool with six domains and 46 questions was circulated amongst registered OMFSs in India. The study consisted of 950 participants. The data obtained from this questionnaire were coded and entered into Statistical Package for Social Sciences (SPSS) and a descriptive analysis was conducted. Results: The study yielded that only 33% of the participants were completely aware of facial fillers and 30.5% were aware of Botox procedure. However, there was complete awareness of blepharoplasty in 42%, cheiloplasty/palatoplasty in 65.8%, laser facial resurfacing in 23.7% and facial rejuvenation in 23.5% of the participants. Discussion: It was found that a high number of OMFSs felt that their exposure to plastic surgery during their post-graduation years was not sufficient.

Effectiveness of a Visual Interactive Game on Oral Hygiene Knowledge, Practices, and Clinical Parameters among Adolescents: A Randomized Controlled Trial.

This study aimed to evaluate the effect of a novel interactive game-based visual performance technique (IGVP) and conventional oral health educational (OHE) talk on plaque control, gingival health, and oral hygiene knowledge and practices in 12−15-year-old schoolchildren. A single-blinded randomized controlled trial was undertaken in a private primary school in Belagavi, Karnataka, India. A total of 100 children aged 12−15 years were randomly assigned to either a conventional OHE talk (control group, n = 50) or the IGVP technique (test group, n = 50), using a computer-generated table of random numbers. A self-designed, pre-validated closed-ended questionnaire was collected from both groups, followed by clinical examination carried out using gingival and plaque index, pre- and post-intervention, at three months follow-up. There was a significant reduction in the mean gingival score and plaque score in the test group after intervention, indicating a 58.7% and 63.4% reduction, when compared to the control group, which had a 2.8% and 0.7% reduction, respectively (p < 0.001). The test group showed a significant increase in the percentage of knowledge gained (22.4%), compared to control group (7.8%). The IGVP technique proved to be more effective than a conventional OHE talk in the reduction of the plaque score, gingival score, and in the improvement of the knowledge of oral hygiene maintenance and its application.
