Musculoskeletal disorders among dental students: a survey from Saudi Arabia.

BACKGROUND: Work-related musculoskeletal disorders (WMSD) are injuries affecting bones, joints, muscles, and tendons due to improper working conditions with serious consequences on health and career. Dentists were found to be at greater risk of developing WMSD compared to other healthcare providers. This study aimed to investigate the prevalence and risk factors of WMSD among dental students in Saudi Arabia. METHODS: This cross-sectional survey-based study recruited dental students across the kingdom using respondent-driven sampling technique. Data was collected using the Nordic Musculoskeletal scale and a validated, self- administered, close-ended questionnaire which assessed WMSDs predisposing factors, enabling factors and musculoskeletal disorders consequences and management. The questionnaire was administered in both Arabic and English languages and was distributed online using google forms. Data analysis was performed using SPSS, Chi-square test or Fisher Exact test was used where appropriate and Multivariate Logistic regression analysis was performed to identify predictors of developing WMSDs. RESULTS: The prevalence of WMSD was 87% (95% CL; 83.9% to 90.3%) among the 462 respondents. Gender, study year, type of practice, having clinics for left-handed, hours of clinical practice, sitting in the proper position while working, use of coping strategies were significantly associated with WMSD prevalence (P < 0.05). Males were OR = 10 times at higher risk of WMSD compared to females (P = 0.0001). Those with daily clinical practice were OR = 5 times at higher risk of WMSD than those who have weekly practice. Those practicing walking, workout, and yoga showed lower prevalence of WMSD (OR = 0.377 & 0.323, p = 0.015, 0.010 respectively). CONCLUSIONS: The prevalence of WMSD among dental students in KSA was high. Males and those with prolonged clinical sessions were at greater risk of WMSD. There is a need for awareness campaigns to educate dental students about risk factors of WMSD. Collegesy, dental colleges should adopt policies in reducing WMSD among their students.

Oral health-related interdisciplinary practices among healthcare professionals in Saudi Arabia: Does integrated care exist?

BACKGROUND: There is a bidirectional relation between oral and general health, therefore collaboration between healthcare providers is needed. This study investigated current interdisciplinary practices (IDP) and the associated factors among healthcare professionals in Saudi Arabia. METHODS: A cross-sectional study was conducted in the Eastern Saudi Arabia recruiting four groups of health professionals (nurses, physicians, pediatricians and Ear-Nose and Throat (ENT) specialists). A validated, self-administered questionnaire was distributed online and shared through social media platforms. The questionnaire explored predisposing factors (demographics) and facilitating factors (knowledge, attitudes, attendance of oral health training and source of knowledge) associated with IDP. RESULTS: A total of 1398 health professionals were recruited. Participants showed fair oral health knowledge (7.1 ± 2.1) and attitudes (22.2 ± 3). Three-fourths (74.6%) reported always providing oral health education (OHE) to their patients, more than half (59.6%) reported always conducting an oral health screening (OHS), two-thirds (66.7%) reported responding to patients' questions about oral health or conditions and 58.7% reported referring patients to dentists. Pediatricians and physicians had greater odds of IDP compared to other health professionals. Source of oral health knowledge (Ministry of Health (MOH) and formal education) was significantly associated with increased odds of IDP. Participants with good oral health knowledge had greater odds of responding to patients' oral health question as well as have more referral practices. CONCLUSION: The results reveal a discrepancy between participants' IDP, knowledge, and attitudes. Incorporating dental component to medical curricula, continuous education and training programs targeting health professionals through Ministry of Health should be considered.

An investigation of dental students' perceptions about the characteristics of effective instructors and their related factors.

BACKGROUND: The characteristics of effective teachers can be used to improve student learning, support their academic achievement outcomes and promote faculty development and career advancement. OBJECTIVES: To assess dental students' perceptions about the characteristics of effective instructors and related factors. MATERIALS AND METHODS: This cross-sectional study analysed data collected from students at a dental college in Saudi Arabia. A pilot-tested questionnaire with satisfactory internal consistency was distributed amongst all students. The questionnaire contained 21 items related to the characteristics of effective instructors on a 5-point Likert-type scale. Student's t test was performed to analyse the association of factors like gender, last year's GPA, academic year, paternal income, education and employment with three highly rated items of the characteristics of effective teachers. RESULTS: The response rate was 85.4%. There were 53.6% female and 46.4% male students in the study. The provision of learning resources (mean 4.3 ± 1.06), demonstration of honesty, ethics and integrity (mean 4.28 ± 0.99) and showing respect and caring attitude (mean 4.24 ± 0.94) were three most highly rated characteristics of effective instructors. Using the latest technology, acting as a role model and maintaining class discipline were the least rated traits of good teachers. A significantly higher percentage of female students considered these three items more important than male students (P < 0.05). The students with last year GPA > 4 considered providing learning material as an attribute of effective teacher significantly more important than the students with GPA ≤ 4 (P < 0.001). In addition, the characteristics of effective instructors (75.1%) were considered more important in providing students with rewarding learning experience than their teaching experience (15.4%) and educational attainment (9.5%). CONCLUSION: The most important attributes of effective teachers included providing learning resources, demonstrating honesty/integrity and showing respect/care.

Peer evaluation as an alternative assessment method for case presentations: A cross-sectional study of dental students' perception.

INTRODUCTION: Peer assessment in dental and medical education is a key tool for evaluating attitudes and communication skills, serving as an effective formative learning method. It not only boosts academic performance and encourages lifelong learning and reflective practice but also fosters collaboration, effective communication, and constructive feedback among peers. OBJECTIVE: This study aimed to assess dental students' satisfaction and perceptions regarding implementing peer assessment in case presentations, including contribution to their learning. METHODS: This cross-sectional study involved third (n = 26), fourth (n = 54), and sixth (n = 71) dental students divided into five groups. Each student received peer assessments (n = 8) from the students of the other groups regarding their clinical presentation. At the end of the process, students were invited to complete an anonymous 9-item questionnaire to assess student perceptions of the peer-assessment process. Data were analyzed to evaluate students' perception and satisfaction with the peer assessment task. The bivariate analysis explored associations among questionnaire items. RESULTS: A total of 151 students participated in the current study. Results showed a high level of agreement for most of the students regarding their preparedness for peer and self-assessment. More than 75% of the students at all academic levels found it challenging to evaluate their peers. Student satisfaction scores increased with the level of education, (4.076, 4.214, and 4.246 out of five, respectively) with moderate correlations between peer evaluation characteristics. CONCLUSION: Peer assessment appears to enhance learning and professional development in dental students. Students' satisfaction with peer assessment grows with education level, reflecting its role in fostering critical evaluation skills and feedback.

Is It Mum or the Dad? Parental Factors That Influence the Use and Acceptance of Fluoride Varnish among Parents in Eastern Saudi Arabia.

Objective: To investigate parental factors that influence knowledge, use, and acceptance of fluoride varnish (FLV) application. Methods: This cross-sectional study was conducted during December 2021. A multistage sampling technique was used to recruit parents with children aged 3 to 6 years and residing in Eastern Saudi Arabia, excluding those working in the dental field. The questionnaire consisted of four parts: demographics, knowledge, previous experience, and acceptance of FLV and was pilot-tested and distributed online using social media. Results: A total of 623 parents responded to the survey. Only 36.9% of parents had good FLV knowledge with dentists being the main source of information. Gender, educational level, family income, being in the medical field, and source of knowledge were factors that significantly (P < 0.05) influenced parental knowledge. Only 24.6% of the parents applied fluoride varnish to their children before, of whom only 29% were satisfied with the experience. Parent's FLV knowledge, view of dental visits, satisfaction with previous experience, perception of children's oral health, and willingness to reapply FLV were factors that significantly (P < 0.05) influenced FLV use. Working in the medical field, perception of dental visits, and the source of knowledge were factors that significantly (P < 0.05) influenced the parent's acceptance to apply FLV. While lack of knowledge about fluoride benefits (15%) was the main reason for parental refusal to apply FLV. Conclusions: The current study highlights the lack of knowledge and application of FLV among parents. There were more factors influencing mothers' acceptance of FLV application compared to fathers. Age, educational level, working in the medical field, perception, and patterns of dental visits were some of the identified factors. Dentists played a major role in parental knowledge and FLV acceptance. In a country with high caries prevalence, preventive programs such as FLV education and application are crucial.

Enamel Remineralization Competence of a Novel Fluoride-Incorporated Bioactive Glass Toothpaste-A Surface Micro-Hardness, Profilometric, and Micro-Computed Tomographic Analysis.

This study aimed to analyze the enamel remineralization efficacy of a novel fluoridated bioactive glass (F-BG) toothpaste compared to a standard fluoride toothpaste. Seventy-two enamel blocks (N = 72) were divided into groups of twenty-four blocks according to the toothpaste exposure-group 1: brushed with distilled water, group 2: brushed with fluoride toothpaste (ColgateTM), and group 3: brushed with F-BG toothpaste (BioMinFTM). Pre-brushing, enamel blocks were demineralized using 6 wt.% citric acid (pH = 2.4). Tooth brushing was performed using a mixture of respective toothpaste and artificial saliva (AS), and each enamel block received 5000 linear strokes. The samples were assessed for surface micro-hardness (to estimate Vickers hardness number, VHN), surface roughness (Ra), and volume loss/gain using micro-computed tomography (micro-CT). The highest increase in the VHN was noticed for group 3 (117.81) followed by group 2 (61.13), and all the intragroup comparisons were statistically significant (p < 0.05). Demineralization increased the Ra values, and a decrease was observed post-remineralization for all the groups. The maximum Ra decrease was observed for group 3 (-223.2 nm) followed by group 2 (-55.6 nm), and all the intragroup comparisons were again statistically significant (p < 0.05). Micro-CT investigation revealed that the enamel volume decreased after demineralization and increased after remineralization among all groups. The F-BG toothpaste showed greater enamel surface micro-hardness (increased VHN), smoother surface (low roughness), and better volume restoration (remineralization) in comparison to the fluoride toothpaste.

Psychological Impact of the COVID-19 Pandemic on Students, Assistants, and Faculty of a Dental Institute of Saudi Arabia.

This study aimed to assess the perceived stress levels in students, assistants, and faculty members of the College of Dentistry, Imam Abdulrahman Bin Faisal, University (IAU), Kingdom of Saudi Arabia (KSA) during the novel coronavirus disease 2019 (COVID-19) pandemic. Using the Cohen's perceived stress scale (PSS) questionnaire (consisting of 14 items, hence called PSS-14), an online observational survey was conducted. The PSS 14 was rated on a 5-point Likert scale ranging from 0 (never) to 4 (very often). The scores ranging from 0-18 represented low stress, 19-37 represented moderate stress, and 38-56 represented high stress. The second-and third-year students were designated as junior year students, while fourth-year onwards were considered senior year students. Out of total 265 participants, 65% (173) were female, and the majority of the participants were dental students 70% (185) with a mean age of 26.71 ± 9.26 years. In the present study, the average PSS score for the participants was computed as 29.89 (range score: 0-56) which shows moderate stress levels among the respondents. The PSS score for the students was 31.03; for the faculty, it was 28, while for the assistants, it was 27.05. Among the three participant groups, the students were found more on the severe stress side (19%) (p-value = 0.002), and among them, the senior year students (6th year) showed significantly higher stress levels compared to the junior year students (p-value = 0.005). Age-wise, the participants below 20 years were most stressed (21%), followed by those 20-30 years old (18%). Female participants were more severely stressed than males (17% vs. 10%, respectively). It was concluded that the students experienced more stress, followed by the faculty members and dental assistants. In addition, younger participants, females, and senior year students were more stressed than their counterparts. Future studies directed at evaluating stress levels of these groups from different dental institutes could provide an opportunity for policymakers to offer various resources to improve their mental health.

In vitro evaluation of probiotic strains for lactic acid production.

BACKGROUND: The growing interest on usage of probiotic lactobacilli in maintaining oral health has posed number of questions on its probable side effects. One such consideration could be an increased acid production in dental plaque, in turn leading to dental caries. Thus, the aim of this study was to comparatively evaluate the lactic acid producing ability of L. acidophilus and L. plantarum with and without dental plaque. MATERIAL AND METHODS: The study consisted of five groups: 3 control groups (Supragingival plaque, L. acidophilus and L. plantarum) and 2 test groups (Supragingival plaque with L. acidophilus and Supragingival plaque with L. plantarum). 26 samples for each group were collected and their baseline spectrophotometric values were recorded. The acid production was initiated by adding 25?l fructose (10%) and stopped by centrifugation for 2 min. The concentration of the lactic acid produced was determined with the aid of COBAS INTEGRA 400 plus. RESULTS: On comparison of Lactic Acid estimation in mg/dl, the mean values of Plaque group was the highest followed by Plaque +L acidophilus, Plaque +L plantarum, L acidophilus and least in L plantarum. The posthoc analysis shows that the comparison of Group 1 (Plaque) and Group 2 (Plaque +L acidophilus) is statistically Significant results between all the groups except between the Plaque +L acidophilus and Plaque +L plantarum group. CONCLUSIONS: The lactic acid producing ability of pure suspensions of L.acidophilus and L.plantarum and the lactic acid producing efficiency becomes more when they are added to the supragingival plaque. Key words:Probiotic, lactic Acid, plaque.
