Nationwide exploration: assessing oral microbiome knowledge among dental professionals in Saudi Arabia and its implications for oral health care.

BACKGROUND: The relationship between the microbiome and oral health is intricate, yet there is a lack of comprehensive knowledge regarding the microbiome's impact on oral health. Integrating knowledge regarding the oral microbiome and its significance in oral and systemic diseases holds profound implications for dental professionals in patient care and professional development. This study assessed dental professionals' oral microbiome comprehension and knowledge levels in Saudi Arabia and its implications for oral healthcare. METHODS: Data were gathered using a cross-sectional design by administering a comprehensive online questionnaire to 253 dental professionals from diverse demographic backgrounds. The questionnaire, administered in English, was divided into four sections: (1) Microbiome awareness and understanding, (2) Diet, nutrition, and microbiome relationship, (3) Microbiome and oral and systemic diseases, and (4) Counselling, education, and implications. Statistical analyses were used to identify and understand underlying patterns, including descriptive statistics, chi-squared tests, ANOVA, and post hoc tests. The Spearman rank correlation coefficient was applied to assess self-rated knowledge. RESULTS: Of the 253 participants, 94.6% were familiar with the term "microbiome." Merely 13% of participants considered the oral microbiome to be the second most diverse, following the gut microbiome. About 39.9% of participants knew the connection between oral mucosal diseases and the oral microbiome. Furthermore, only 6.7% thought there was a connection between systemic diseases and the oral microbiome. Participant comprehension of oral microbiome questions averaged 9.19 out of 13, with 83.7% scoring "good". There were significant differences in knowledge scores among dental specializations (F = 7.082, P < 0.001) and years of professional experience (F = 4.755, P = 0.003). Significantly, 53.8% of participants had uncertain self-perceptions of their knowledge of the oral microbiome, while only 0.8% rated their understanding as 'very good'. CONCLUSION: Our findings reveal that dental professionals have varying levels of awareness and comprehension of the oral microbiome. Despite widespread awareness, understanding its diversity and implications for oral and systemic health remains limited. It is essential to address these gaps in knowledge through future research and educational interventions, considering the vital part that dental professionals play in promoting oral health through personalised dietary recommendations, lifestyle changes, and hygiene practices. These initiatives may promote a robust oral microbial community, enhance patient outcomes, and advance oral healthcare locally and globally.

Questionnaire-Based Study on the Prevalence, Awareness, and Preventive Measures of Occupational Hazards Among Dental Professionals.

BACKGROUND In this questionnaire-based study, we evaluated the prevalence and awareness level of occupational hazards among dental professionals (students, interns, dentists, and specialists) at different dentistry colleges. MATERIAL AND METHODS A self-administered questionnaire was designed from previously conducted studies and distributed to 310 participants from different dental colleges of dentistry in Sana'a City, Yemen. The questionnaire was divided into 4 parts. The first part comprised questions involving sex, age, and clinical professions; the second part, questions on awareness about different occupational hazards; the third part, questions about prevalence of occupational hazards; and the fourth part, questions related to bringing down the prevalence of occupational hazards associated with a dental practice. Data were analyzed using one­way analysis of variance and chi-square tests. RESULTS Significant differences were detected between sex, age groups, and clinical professions. Musculoskeletal disorders were the most common physical hazard, whereas infections were the greatest biological hazard, accounting for 68% and 74%, respectively. Of the participants, 63.5% answered that "patient, practice, and finance'' together were the most common causes of stress among practicing dentists and dental students. The use of gloves and/or masks was the most efficient preventive measure among participants. A significant difference was found among most of the parameters, with P≤0.001. Almost 50% of respondents answered "yes'' in relation to vaccination for hepatitis-B, with P=0.062. CONCLUSIONS The prevalence of occupational hazards was low among dentists and dental students among the tested participants, with significant differences for most of the parameters.

Levels of Depression, Anxiety, and Stress Among Saudi Arabia's Medical and Dental Practitioners: A Cross-Sectional Study Following the Covid-19 Pandemic.

BACKGROUND Healthcare providers, particularly in dentistry and medicine, experience high stress levels, exacerbated by factors like patient anxiety, clinical work, and continuous training. The COVID-19 pandemic has further increased these risks. This study aimed to assess depression, anxiety, and stress (DAS) among dental and medical practitioners in Saudi Arabia, investigating influential factors on their psychological behavior. MATERIAL AND METHODS In this cross-sectional study conducted in July and August 2021, the depression, anxiety, and stress scale (DASS-21) was administered through a Google questionnaire. Data analysis involved stepwise mode modeling and bivariate analysis, with a significant P value <0.05, using the Statistical Package for the Social Sciences. RESULTS The study included 376 dentists and 201 medical practitioners. Most worked more than four days a week, slept under six hours nightly, and were non-smokers. DAS scores indicated depression (51.7-57.4%), anxiety (50.7-58.2%), and stress (54.2-60.1%). Significant differences (P<0.05) were observed among younger, single, female, and lower-income participants. Higher DAS scores correlated with less sleep, extensive social media use, and smoking history. Socio-demographic factors were mostly non-significant for medical practitioners, except social media use. Sleep duration significantly impacted stress levels, while specialty, income, and marital status influenced depression CONCLUSIONS DAS levels were notably higher in dentists compared to medical practitioners, particularly regarding anxiety. The impact of socioeconomic factors varied, being more statistically significant for dentists.
