Comparison of virtual clinical scenario and role play in learning oral pathology among dental students.

In oral pathology, virtual clinical scenario illustrating dentist-patient interactions can be utilized by both students and health professionals to deliver/gain knowledge and make clinical diagnosis of oral lesions. Role play is also an educational technique which is designed to engage and motivate students in classrooms. This study aimed to compare usefulness of virtual clinical scenario and role play in learning oral pathology among second-year dental students. The students were randomly divided to one of the two groups: virtual clinical scenario group (n = 50) and role play group (n = 50). Virtual clinical scenario group was provided with virtual clinical cases of oral lesions through Google Forms whereas role play group was exposed to virtual clinical cases of oral lesions through role playing activity. Both groups underwent assessments before and after the intervention. Students' perceptions on usefulness of both techniques in terms of diagnosis, visual parameters and impact on learning were evaluated by feedback questionnaire. Data were analyzed using Statistical Package for the Social Sciences version 27.0. Wilcoxon signed-rank test was used to compare pre-test and post-test scores. Additionally, the scores and students' responses from both groups were compared using the Mann-Whitney U test. A P-value of < 0.05 was set as statistically significant. Students in both groups showed significantly higher post-test scores compared to their pre-test scores (P < 0.001). However, the role play group outperformed the virtual clinical scenario group, with a significantly higher post-test score (P = 0.04). Furthermore, feedback concerning role play was significantly higher than that for the virtual clinical scenario across multiple aspects (P < 0.05). Our findings suggest that role play emerges as the preferred method, significantly enhancing dental students' learning experiences in oral pathology.

Salivary aquaporin-3 as a screening biomarker for xerostomia in patients with periodontal disease and the effects of xerostomia on oral health-related quality of life.

Xerostomia is a subjective condition of dryness of the oral cavity that may lead to several oral problems deteriorating oral health-related quality of life. This study aimed to (1) determine the prevalence of xerostomia, (2) compare the general health status, unstimulated salivary flow rate, and oral health-related quality of life in xerostomics and non-xerostomics, and (3) investigate the potential of salivary aquaporin-3 (AQP-3) as a screening biomarker for xerostomia in patients with periodontal disease. Demographics and systemic health data were collected from 109 healthy participants, 20 to 55 years old, with Community Periodontal Index (CPI) score ≥ 3. For subjective assessment of xerostomia, Shortened Xerostomia Inventory (SXI) was used. For objective assessment of xerostomia, unstimulated salivary flow rate was measured. Shortened Oral Health Impact Profile (S-OHIP) was utilized for oral health-related quality of life assessment. The collected saliva samples were processed and stored at -80°C. Quantification of salivary AQP-3 protein was done with enzyme-linked immunosorbent assay. Xerostomia was reported in 78% of the subjects based on SXI score. Median concentration of AQP-3 was significantly higher in xerostomics compared to non-xerostomics, p = 0.001. Moreover, oral health-related quality of life was significantly poor in xerostomics compared to non-xerostomics, p = 0.002. Furthermore, there were significant correlations between AQP-3 and SXI (r = 0.21, p = 0.025), AQP-3 and S-OHIP (r = 0.2, p = 0.042), S-OHIP and SXI (r = 0.37, p < 0.001), unstimulated salivary flow rate and random blood glucose level (r = 0.32, p = 0.001), and body mass index and mean arterial pressure (r = 0.44, p < 0.001). Regression analysis showed that body mass index, CPI score 3, and salivary AQP-3 were suitable predictors for presence of xerostomia. AQP-3 could be a potential screening biomarker for xerostomia in patients with periodontal disease for its early identification may help improve oral health-related quality of life of the individuals.

From text to e-text: perceptions of medical, dental and allied students about e-learning.

Objective: More than a year ago, Pakistan like the rest of the word, was hit by a global pandemic, due to which students of higher education had to accept the new era and adapt to the electronic learning environment for the very first time. This study aims to analyze the perceptions of medical, dental, and allied health students about e-learning in Pakistan. Methods: A descriptive, cross-sectional study was conducted throughout the country. A pre-validated, anonymous online questionnaire regarding demographics, past-experience of e-learning, advantages disadvantages of e-learning, and general perception of students towards e-learning was distributed. Descriptive statistics were computed for all demographics. Chi-square test was used to compare the differences of perceptions between pre-clinical year and clinical years students. Chi-square was used to compare overall category-wise positive and negative responses of students. The association between participant demographics and their perception towards e-learning was also calculated using chi square. Results: A total of 1200 students participated in the study of which 797 (66.4%) were from pre-clinical years and 403 (33.6%) were from clinical years. The major advantage identified by all students was the 'comfortable environment' (70%) and 'technical problems with IT equipment' was listed as the biggest disadvantage (89%) of e-learning. For preclinical year students, 'anxiety due to social isolation' was selected as the biggest issue (p < 0.05) whereas, for clinical year students, it was 'lack of patient interaction' (p < 0.05). Overall, 72% of students had a negative perception of e-learning. Conclusion: After more than a year of online studying, medical and allied students of Pakistan have expressed dissatisfaction towards e-learning. Student-teacher training, student counselling sessions, and innovative techniques need to be introduced to enhance student engagement and reduce pandemic stress.

Salivary and imaging-based biomarkers of radiation therapy-induced xerostomia.

Biomarkers are anatomical characteristics or naturally occurring measurable molecules indicating physiological or pathological state of an individual. These biomarkers have the potential to detect or predict diseases at an early stage, which is particularly beneficial in timely management of common complications of radiation therapy done in head and neck cancer treatment regime. Xerostomia is one of the most common oral complaints of radiation therapy. Saliva has an abundance of protein biomarkers; however, those related to post-radiation therapy xerostomia need to be explored further. Textural and imaging-based biomarkers are helpful in predicting xerostomia in such patients. This narrative review provides an account of salivary protein and imaging-based biomarkers of radiation therapy-induced xerostomia in head and neck cancer patients.

Determining the relationship among stress, xerostomia, salivary flow rate, and the quality of life of undergraduate dental students.

OBJECTIVE: Xerostomia may result in several oral conditions, which ultimately affect oral health-related quality of life (OHRQOL). This study aims to evaluate the relationship of stress, xerostomia, salivary flow rate, and OHRQOL among young adults. METHOD: We invited 72 participants to complete three validated questionnaires including the Perceived Stress Scale-10 (PSS-10), a shortened version of the Xerostomia Inventory (SXI), and the shortened Oral Health Impact Profile (S-OHIP). Unstimulated saliva was collected, and flow rate was determined. Based on the SXI scores and hyposalivation, the participants were categorised into four groups: subjective xerostomia, subjective and objective xerostomia, objective xerostomia, and true non-xerostomia. Based on the median PSS score, participants were categorised into high stress and low stress groups. Data were analysed using the Mann-Whitney U test, Kruskal-Wallis H test, and Spearman's correlation coefficient. A p value of 0.05 was set for all tests. RESULTS: A significant difference was observed in the unstimulated salivary flow rate (χ2(3) = 26.677, p < 0.001) and PSS scores (X2(3) = 8.552, p = 0.036) between xerostomia groups, while OHIP scores were not statistically different (X2(3) = 5.488, p = 0.139). A significant correlation was observed between SXI and S-OHIP scores (r = 0.348, p = 0.003) and unstimulated salivary flow rate and PSS (r = -0.259, p = 0.028). CONCLUSION: This study shows that perceived stress can influence salivary flow rate. Among the xerostomia groups, stress scores and salivary flow rates varied significantly. Additionally, subjective xerostomia has an impact on OHRQOL.
