Attitude of Dental Students Toward Rubber Dam Application: A Cross-Sectional Study.

Introduction The rubber dam (RD) system is globally recognized as an indispensable component of dental treatments, ensuring the highest standards of care. The use of RD isolation profoundly impacts the clinical aspects of dental procedures. The aim of this study was to assess the attitudes of dental students toward the use of RD, with an emphasis on evaluating the factors influencing its use among students at Umm Al-Qura University in Makkah city, Kingdom of Saudi Arabia. Methods An online questionnaire was distributed to a population sample of 203 undergraduate dental students in their clinical years at Umm Al-Qura University. Questions covered various aspects, including the frequency of RD use, perceptions of its effectiveness, and prospective intentions for its future use, as well as factors influencing these attitudes. Statistical analysis was performed using SPSS software Version 26 (IBM Corp., Armonk, NY, USA). In addition, the chi-square test and Fisher-Freeman-Halton exact test were used for the comparison of the data at a significance level of p<0.05. Results The questionnaire was completed by 191 participants, with a response rate of 95.5%. Of the students, 189 (99%) used RD during operative procedures for adhesive restorations. Furthermore, 157 (82.2%) students agreed that proper isolation cannot be achieved without RD application. All the advantages of RD application were recognized by 165 (85.9%) of the students. Notably, there was a significant association between the factors limiting the RD application and the students' academic year (p<0.05), with senior students reporting fewer limitations. Responses indicated that 163 (85.3%) of the students received satisfactory training for RD and 165 (86.4%) students had a high intention to continue using RD following graduation. Conclusion Within the limitations of this study, it can be concluded that the results presented a positive attitude toward RD use. However, there is a continued necessity to enhance education and advocate consistent RD application for improved patient care and clinical outcomes.

Effect of different types of smoking on oral health and on cellular changes in oral mucosa.

Objectives: Smoking is known to be a major risk factor for several diseases. Recently, electronic cigarettes have been introduced to the market; however, their effect on oral health has not been well studied yet. We aim to compare the effect of different types of smoking on oral health and to evaluate cytomorphological changes in oral mucosa among different types of smokers. Study design: A total of 112 participants were recruited, conventional cigarette smokers (n = 28), electronic cigarettes smokers (n = 26), hookah smokers (n = 29) and non-smokers (n = 29). Oral examination, brush cytology and salivary flow test were performed. Cytological smears were stained and examined for cytomorphological changes. Oral symptoms, type, and frequency of smoking were obtained through questionnaires. SPSS program was used for statistical analysis. Results: Most of the oral symptoms reported in this study were among conventional and electronic cigarettes smokers. While hookah smokers reported the least oral symptoms. Increase in DMFT and gingival index were observed among all smokers, mainly among conventional cigarettes smokers. Conventional cigarette and hookah smokers were found to have the most significant cellular changes. Electronic cigarette smokers had certain cellular changes as well. Conclusion: All types of smoking adversely affect oral health and can induce cellular changes in the oral mucosa.

Physical Activity and Psychological Wellbeing Among Healthcare Students During the COVID-19 Pandemic.

INTRODUCTION: Regular physical activity (PA) contributes to physical and mental wellbeing. Due to coronavirus disease 2019 (COVID-19)-related lockdowns in 2020, regular PA had been adjusted. Furthermore, students became accustomed to studying at home. Students in the healthcare field, in particular, have a better understanding of the link between PA and mental health. This study aimed to assess the association between psychological wellbeing and PA among healthcare students at one public university in Saudi Arabia during the COVID-19 pandemic period. METHODS: This was a cross-sectional study conducted between November 2021 and February 2022. Healthcare students at one public university in Saudi Arabia were invited to participate in an online survey, consisting of three sections. The first section contained questions about demographic data. The second section was the International Physical Activity-Short Form (IPAQ-SF), which is composed of seven questions designed to assess the level of PA. The third part is The Center for Epidemiological Studies Depression Scale (CES-D), which is a self-reported questionnaire comprising 20 questions that assessed depressive symptoms on a four-point scale. Descriptive statistics, Chi-square test, Mann-Whitney U test, and Kruskal Wallis test were used to analyze the collected data using IBM SPSS Statistics for Windows, Version 28.0 (Released 2021; IBM Corp., Armonk, New York, United States). RESULTS: The total responses received were 197 (response rate=60%). The majority of students in this sample were performing inadequate PA and reported depressive symptoms. No association was found between the amount of PA practiced and psychological wellbeing. There was a significant difference between specialties in relation to PA. CONCLUSION: The majority of students in this sample were performing inadequate PA and reported depressive symptoms during the COVID-19 lockdown. The importance of PA should be promoted among healthcare students.
