A Chi-square test assessed whether the best cleanliness would demonstrate a significant association with one irrigation protocol; odds ratio calculation was performed using score "1" versus score "2 or more" (2+) ( < 0.05). In the apical region, cleanliness was better in RI+ than SI and both significantly better than RI. Odd ratios indicate that the cleanliness in RI+ was significantly better than RI and SI groups ( < 0.000 and 0.003, respectively). Independently of the irrigation protocol, EDX analyses showed no chemical alteration of root dentin. Using 17% EDTA during shaping, followed by 3% NaOCl rinse for 3 minutes, improved apical cleanliness without inducing erosion of dentin.

The main aim of this study was to determine the undergraduate dental students' self-reported effectiveness of online classes offered by various dental institutes of Pakistan. A cross-sectional study was conducted using an online survey. A pretested and validated questionnaire comprising of 31 questions was circulated among dental students. The study participants were inquired about the perceived level of accessibility of resources and the effectiveness of online teaching. The data was analyzed using SPSS version 24. Selleck TGF-beta inhibitor Mann-Whitney U test and Kruskal-Wallis test were used for statistical analysis at ≤0.05. A total of 1,207 students from all over Pakistan responded. The majority of students was dissatisfied with the institutional learning management system and quality of learning resources available. Students were also dissatisfied with the level of training of teachers for online lectures. The worst rating was reported for questions related to the effectiveness of online classes (average rating 3.83 and 3.781/5). First-year students reported poor interaction with teachers ( < 0.001) and strongly disagreed with the effectiveness of online classes (mean rating 4.14 ± 0.935). The results from the present survey showed that dental students of Pakistan unanimously voiced dissatisfaction toward various elements of online teaching sessions. Findings from this survey will aid the academic institutes to establish proficient learning platforms focused on improving students` learning experience.

Curcumin promotes oral wound healing; however, the underlying mechanism remains unknown. We hypothesized that curcumin may regulate gene expression in human gingival fibroblasts (hGFs). This study investigated the effect of curcumin on the expression of wound healing-related genes, collagen type I (COL1), keratinocyte growth factor (KGF)-1, and epidermal growth factor receptor (EGFR), in the wound healing model of hGFs, as well as the signaling pathway involved in the regulation of these genes by curcumin. The hGFs were treated with curcumin in the unwounded condition and in the wound healing model (scratch assay). Gene expression was determined by quantitative polymerase chain reaction. PD98059 was used to elucidate whether extracellular signal regulated kinase (ERK) signaling is involved in the curcumin-regulated gene expression in hGFs. Cell migration was also analyzed by the scratch assay. Data were analyzed by independent -test or one-way analysis of variance (ANOVA) followed by Tukey's Honestly Significant Difference ( HSD) test. In unwounded hGFs, curcumin significantly increased KGF-1 and EGFR expressions
