Students have unique preferences when it comes to knowledge acquisition, information processing, retention in memory, and recall. This study is aimed at examining the preferred learning styles of medical and dental undergraduate students of Pakistan. It is also aimed at investigating the influence of gender, preclinical or clinical academic year, and academic record on the preferred learning style. A descriptive cross-sectional study was conducted in Pakistan. The learning styles of undergraduate students were identified using visual, aural, read/write, and kinesthetic (VARK) questionnaire. Students were also asked about their satisfaction towards teaching style of their teachers in institute. Descriptive statistics were done to characterize the learning styles of the students. The Fisher test and chi-square test were used to compare the learning preferences between genders and public/private sector students and among preclinical/clinical years. A p value of less than 0.05 was considered significant. A total of 1473 students participated in the study. Among the students, 39.37% preferred unimodal learning style whereas 60.62% preferred multimodal style. Kinesthetic (K) and visual (V) were the most preferred unimodal styles. The preferred learning styles of female students are aural (A), visual (V), and kinesthetic (K), whereas male students preferred visual (V) and kinesthetic more (K). Students with lower academic record chose unimodal styles in comparison to high achievers that chose multimodal styles. Students of clinical year preferred multimodal and quadmodal styles in comparison to preclinical year students. An alarming 78% of students were dissatisfied with their teacher’s instructional style. Majority of students prefer multimodal learning styles over unimodal style. Gender, public/private sector, and academic record have influence on the preference of learning styles. Majority of the students are dissatisfied with their teacher’s instructional style and rely on social media platforms for understanding. Academics need to adapt their teaching methods according to student preferences in order to get better graduates.
BACKGROUND: Halitosis or oral malodor is characterized by unpleasant odor arising from the oral cavity. The prevalence of halitosis however is not studied extensively. METHODOLOGY: A structured questionnaire consisting of 15 questions was administered to 220 undergraduate students of Sharif Medical and Dental College, Lahore. RESULTS: Out of them 212(96.36%) students participated in the study. Among them 90(42.45%) were males and 122(57.55%) were females. Mean age of the students was 20.48±1.63 years. Average age of male was 21.41±1.66 years and of female was19.79±1.22 years. 89(42.0%) reported halitosis (95% C.I 35.3% to 48.9%), 90(42.5%) have no halitosis and 33(15.6%) did not know about It. Halitosis was reported among 30(33.3%) male and 59(48.4%) female. Present study showed that females have more awareness of malodor than the male students. CONCLUSION: The results of this study indicate higher prevalence and awareness of halitosis among this population consisting of dental students. The awareness of halitosis as an individual entity should be promoted to the general population and the therapeutic measures should be made available to all.
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 (χ 2 (3) = 26.677, p < 0.001) and PSS scores (X 2 (3) = 8.552, p = 0.036) between xerostomia groups, while OHIP scores were not statistically different (X 2 (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.
Background: Frozen section based histological diagnosis is required by the surgeon(s) to make immediate intraoperative decision(s) So, high accuracy of frozen section is important for the reporting surgical pathologist(s) and surgeon(s) to make subsequent on-table decision for the management of the patient. Objective: To assess the concordance of frozen section histological diagnosis reported in our institute by comparing it with subsequent final histological diagnosis. Material & Methods: Biopsy specimens 100 patients submitted for frozen section diagnosis were included in the study. The diagnosis rendered on fresh frozen section was compared with the diagnosis rendered on paraffinembedded formalin-fixed section of the same specimen. Results: Male-to-female ratio of the patients included in the study was 2:1 with mean age of 48.70 years. The diagnosis could be rendered in 99 cases, while in 1 case diagnosis was deferred to permanent sections (deferral rate: 1%). There was no difference found between the frozen section diagnosis and the final diagnosis in 97 (concordance rate: 97.9%) cases. Conclusion: Frozen section-based histological assessment for diagnosis and/or surgical resection margins status is a reliable technique in terms of its timely and accurate reporting and low deferral rate.
Objective: In this study the effects of carbonated drinks on the healing process of oral submucosa of albino wistar rats were evaluated. Design: This study comprised of 24 adult albino wistar rats which were randomly assigned to a experimental group 1 and an experimental group 2. A circular wound of 3.0 mm was created on the buccal mucosa of each albino wistar rat at day 0. Animals in control group were fed with chow pellet and water while those in experimental group were fed with chow pellet and a commercially available carbonated drink instead of water. 6 animals from each group were sacrificed by decapitation under deep anesthesia at day 7 and 21. The tissue dissected from buccal area was serially sectioned and stained with Haematoxylin & Eosin stains. Wound site was histologically assessed for differences in the healing pattern of submucosa; inflammatory cell count and neovascularization between two groups. Results: There was a marked difference in the healing pattern between the two groups. Animals in group-1 showed a normal healing pattern with formation of a fibrous connective tissue at the end of day-21. In the group-2, there is altered healing phenomenon at the end of the experiment with a subsequent delayed inflammatory reaction at day-21 Conclusion: These findings suggest that consumption of carbonated drinks can disrupt oral wound healing. The contents in carbonated drinks have a proinflammatory action on the soft tissue.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
