Abstract

Mental illness is a psychological impairment involving emotions, cognitions, and behaviors, and its prevalence is increasing worldwide. Dental students may encounter patients with underlying psychological problems during their training. Objective: To evaluate dental students’ perception, attitude, and willingness to interact with patients with mental illness. Methods: A multi-center cross-sectional study was conducted involving undergraduates at three dental institutions in Malaysia using an online self-administered questionnaire. Descriptive data analysis was conducted and statistical analysis using chi-square test was done for associations (p < 0.05). Results: The response rate was 63% (225); the majority of respondents were female (77.8%) and of Malay ethnicity (88.4%). Our study found that positive attitudes are independent of respondents’ sociodemographic profiles. No significant differences in attitudes were portrayed by gender, race, or history of mental illness. Our findings suggest that respondents’ place of study, gender, and previous encounter with mental illness are associated with willingness to interact with patients (p < 0.05). Conclusions: Dental students displayed positive attitudes and willingness to interact with patients with mental illness. However, to further improve students’ attitudes and enhance their readiness to interact with patients with mental illness, more mental health-related educational programs should be introduced in the dental curricula.

Abstract

Objectives: The human amniotic membrane (HAM) is a promising scaffold for oral applications due to its antimicrobial properties, which help protect against bacterial degradation. However, evidence of its activity against oral bacteria remains limited. Thus, this study aimed to evaluate the antibacterial activity of the HAM against selected Gram-positive oral bacteria, namely, Streptococcus mutans (S. mutans), Streptococcus sobrinus (S. sobrinus), and Enterococcus faecalis (E. faecalis). Methods: HAM in 1 cm2-pieces was inoculated with bacterial suspensions and incubated at 37 °C in 5% carbon dioxide (CO2) for 48 hours to evaluate its inhibition activity. Tetracycline-30 and 0.2% Chlorhexidine served as the positive controls, while phosphate-buffered saline (PBS) was used as the negative control. Swabs from the inhibition zone were re-cultured on Mueller-Hinton agar to test for the bacteriostatic and bactericidal effects of the HAM. Results: HAM inhibited the growth of S. mutans and S. sobrinus but showed no activity against E. faecalis. It also exhibited bactericidal effects against both the Streptococcus species. A statistical analysis revealed a significantly smaller inhibition zone for the HAM compared with the positive controls, while there was no significant difference compared to the PBS. Conclusion: The human amniotic membrane (HAM) demonstrated antibacterial and bactericidal activity against the selected Streptococcus species, but not E. faecalis. The antibacterial properties of HAM against other oral pathogens require further studies to explore its potential as an oral scaffold.
