Abstract

Academic stressors in a medical educational environment are related to two factors. This study was carried out in order to analyze the correlation between the dental environment and perceived stress among dental students during the COVID-19 pandemic. The respondents were 422 undergraduate dental students and the validated Modified Dental Environmental Stress (DES) and Perceived Stress Scale (PSS) questionnaires were used. Furthermore, the Spearman correlation analysis was used to measure the correlation between DES and PSS score. The result showed that five dental stressors were noted to have the strongest correlations with PSS (p-value >0.40). They include expectation towards dental school (p-value = 0.431), lack of confidence to be a successful dentist (p-value = 0.424), lack of confidence to become a successful dental student (p-value = 0.408), dental school regulations (p-value = 0.401) and criticism of school work (p-value = 0.400). In addition, all six DES categories showed a positive correlation with the PSS. Therefore, the dental students collectively displayed moderate perceived stress scores. The overall discoveries from this study showed a positive correlation between the DES and PSS among dental students during the COVID-19 pandemic.

Abstract

Background: Tooth extraction is a common dental procedure often complicated by postoperative infections, with Staphylococcus aureus as a key opportunistic pathogen. Rising antibiotic resistance and side effects of conventional antiseptics like chlorhexidine highlight the need for natural alternatives. This study evaluated the antibacterial and antibiofilm potential of 96% ethanol extract from Ziziphus mauritiana leaves against S. aureus. Methods: The extract was prepared by maceration and tested in vitro using microdilution for minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) against S. aureus ATCC 25923. Antibiofilm activity was assessed via crystal violet staining on mature biofilms, with confirmation by qPCR-based absolute quantification of bacterial load using S. aureus-specific 16S rRNA primers. Statistical analysis included Shapiro–Wilk, ANOVA, and Tukey HSD tests. Results: The extract showed MIC between 125–250 mg/mL and MBC at 250 mg/mL. Concentrations of 1000, 500, and 250 mg/mL inhibited >80% biofilm biomass, comparable to 0.2% chlorhexidine. qPCR confirmed significant bacterial load reduction at 1000 and 500 mg/mL. Conclusions: Z. mauritiana leaf extract demonstrates promising antibacterial and antibiofilm activity against S. aureus, supporting its potential as a natural agent for managing post-extraction infections, though further studies on clinical isolates, cytotoxicity, and formulations are warranted.
