Background This systematic review and meta-analysis were conducted to investigate the effects of live and video demonstrations of various dental procedures on undergraduate students’ performance and satisfaction scores. Materials and methods A comprehensive search was conducted across multiple databases, including MEDLINE (OVID), PubMed, Scopus, and Web of Science, supplemented by a manual search of bibliographic references from retrieved articles. The aim was to identify relevant randomized controlled trials and quasi-experimental trials that compared live demonstrations to video demonstrations in dental education, specifically focusing on undergraduate students’ performance and satisfaction scores assessed using practical assessment rubrics and satisfaction questionnaires. The quality of included studies was assessed using the modified Downs and Black quality assessment tool. Results A total of 3686 studies were identified, of which 2222 studies remained following duplicate removal. Based on title and abstract screening 2188 studies were excluded and full text of 34 studies were comprehensively appraised for eligibility. This resulted in the inclusion of 10 studies in the systematic review, nine of which were classified as good, while one study was considered as fair. Of these, 8 studies were included in the meta-analysis.Students’ feedback reveals distinct preferences, with video demonstrations being commended for repeatability and clarity, while live demonstrations were valued for real-time interaction and guidance. Meta-analysis revealed that video-based learning significantly enhanced educational outcomes across various measures, including knowledge acquisition and practical skills over live demonstrations. Conclusion Video demonstrations emerge as viable alternatives to live demonstrations in dental education for teaching clinical procedures. Video demonstrations offer distinct benefits, including accessibility and repeatability, while live demonstrations provide essential interactive opportunities that contribute significantly to the learning experience in dental education.

The aim was to assess the clinical and radiographic peri-implant status among type-2 diabetic and non-diabetic individuals with major depressive disorders (MDD). Participants were divided into four groups; Group-1: patients with type-2 diabetes; Group-2: patients with MDD; Group-3: patients with type-2 diabetes and MDD; Group-4: healthy controls. Demographic data was collected, and medical history including most recent hemoglobin A1c (HbA1c) levels were retrieved from healthcare records. Peri-implant modified plaque and gingival indices (MPI and mGI) and peri-implant probing depth (PPD) were recorded; and crestal bone loss (CBL) was measured. Sample-size was estimated using data from a pilot investigation. Statistical analysis was performed using one way-analysis of variance and Bonferroni Post-hoc adjustment tests. P-vales below 0.05 were considered statistically significant. Thirty, 30, 30 and 30 individuals were included in groups 1, 2, 3 and 4. Mean HbA1c levels were higher in groups 1, 2 and 3 compared with Group-4 ( P  < 0.05). Thirty-seven, 40, 43 and 36 implants were present in groups 1, 2, 3 and 4, respectively. In groups 1, 2, 3 and 4, the implants were in function for a mean duration of 4.7 ± 2.4, 4.9 ± 1.8, 5.05 ± 1.7 and 10.6 ± 2.2 years, respectively. The mPI, mGI, PPD and CBL were significantly higher in groups 1, 2 and 3 than individuals in Group-4 ( P  < 0.05). There was significant correlation between peri-implant PD and HbA1c levels among individuals in Group-1 ( P  < 0.05). Peri-implant soft tissue and osseous statuses are compromised among patients with type-2 DM, and MDD regardless of whether these conditions occur individually or in combination. Clinical relevance: Peri-implant soft tissue and osseous statuses are compromised among patients with type-2 DM, and MDD regardless of whether these conditions occur individually or in combination.

Background There are a limited number of clinical studies in indexed literature that have assessed the survival of dental implants among patients with systemic cancers undergoing chemotherapy. The present observational study aimed to assess the survival of dental implants in patients undergoing chemotherapy. Materials and methods The primary outcome variable was the survival of dental implants in patients undergoing chemotherapy. Participants were categorized into two groups: Test Group, consisting of patients who had undergone dental implant placement and were currently receiving chemotherapy for systemic cancers, and the Control Group, comprising systemically healthy individuals who had undergone dental implant therapy (DAT). The peri-implant modified plaque and bleeding indices (mPI and mBI), probing depth (PD), and crestal bone loss (CBL) were assessed. Data normality was assessed and group comparisons were done. Level of significance was set at P  < 0.05. Results Twenty-five (14 males and 11 females) and 28 (15 males and 13 females) individuals were included in the test and control groups, respectively. The mean age of individuals in the test and control groups were 69.6 ± 3.7 and 66.1 ± 4.7 years, respectively. Individuals in the test group were diagnosed with cancer 1.3 ± 0.3 years ago and were currently being treated with 5-fluorouracil and carboplatin in three-cycles. In the test and control groups, 15 and 35 implants, which were in function for 2.4 ± 0.6 and 5.7 ± 0.2 years, respectively were subjected to clinical and radiographic evaluation. There was no difference in the mean scores of mPI, mBI, PD and CBL in the test and the control group. In the test control group, the implant survival rates were 60% and 100%, respectively. Conclusion Chemotherapy is not an absolute contraindication for DAT; however, the long-term survival of implants in these individuals is uncertain.
