Strength of motivation of 1st year dental students of a dental institution: A cross-sectional study.

Objective: The study aims to evaluate the motivation levels of dental students, with an emphasis on first-year BDS students, by utilizing the Strength of Motivation for Medical School (SMMS) questionnaire. Methods: It was a descriptive cross-sectional quantitative study targeting 89 first-year BDS students enrolled at Lahore Medical and Dental College from 5th June to 18th August 2023. The Strength of Motivation for Medical School (SMMS) questionnaire was given to the participants after ethical board approval. Data analysis was done through SPSS version 26. The SMMS score was presented as the means standard deviation and an independent t-test was used to find the difference between the groups. The maximum score possible is 80 and the minimum is 16. The higher the score, the greater the strength of motivation. Results: In this study, a total of 89 first-year BDS students completed motivation questionnaires, with 34.8% males and 65.2% females. The average age was 19.92 ± 3.13. The overall Strength of Motivation Score (SMMS) averaged 45.53 ± 6.82. Results indicated 9% low, 89.9% moderate, and 1.1% strong motivation. Females had a slightly higher mean SMMS (45.93 ± 6.88) than males (44.80 ± 6.76), but the difference was deemed insignificant (p = 0.462) via independent t-test. Conclusion: Motivation is vital to achieving excellence in academic pursuits. Nevertheless, there isn't a single criterion that can be utilized to assess success and motivation. Our primary focus must be on every possible outcome of success, not just the scoring criteria.

Oral assessment of children with autism spectrum disorder in Rawalpindi, Pakistan.

Comparison of oral health status, dental needs and dietary habits of children with autism and their healthy siblings. In this cross-sectional study, oral hygiene measures, sugar consumption and dental examination of 58 Pakistani children with autism spectrum disorder were assessed and compared to 27 of their siblings without autism spectrum disorder. Questionnaires were distributed to their parents regarding oral hygiene measures, dietary habits and past dental experiences. Clinical examination for the presence of dental caries, periodontal disease or parafunctional habits was carried out and findings were associated with the mother's education. Children with autism had a higher incidence of caries (50%) as compared to their healthy siblings (22.2%). Significant differences were observed between the groups regarding frequency of brushing and independent brushing. Dental plaque was observed on anterior teeth in 24% children with autism spectrum disorder as compared to 14% in the control group. Trauma due to self-injurious behaviour and bruxism was also recorded and compliance during clinical examination was noted in children with autism spectrum disorder. There was no significant difference in sugar consumption between children with autism spectrum disorder and their healthy siblings. Children with autism had greater dental needs and were more prone to developing dental problems as compared to their healthy siblings.

Microwave-assisted synthesis and in vitro osteogenic analysis of novel bioactive glass fibers for biomedical and dental applications.

Glass fiber-based materials have gained interest for use in biomedical and dental applications. The aim of this study was to make E-glass fiber bioactive by a novel method using the microwave irradiation technique. Industrial E-glass fibers were used after surface activation with the hydrolysis method. The ratio of calcium and phosphorous precursors was set at 1.67. After maintaining the pH of the calcium solution, E-glass fibers in two ratios, i.e. 30% (nHA/E30) and 50% (nHA/E50) wt/wt, were added. The phosphorous precursor was added later and the solution was irradiated in a microwave to obtain nano-hydroxyapatite (nHA) particles on E-glass fibers. The structural, physical and in vitro biocompatibility analyses of the resulting materials were conducted. The expression of osteopontin (OPN) and collagen (Col) type 1 was measured by reverse transcription polymerase chain reaction (RT-PCR) and comparison was made between all the groups. Fourier transform infrared spectroscopy and x-ray diffraction showed characteristic peaks of nHA, and a change in the peak intensities was observed with an increase in the concentration of E-glass fibers. Scanning electron microscopic (SEM) images confirmed the homogenous adhesion of nHA spherical particles all over the fibers. Cell viability with mesenchymal stem cells showed growth, proliferation, and adhesion. All the materials were able to upregulate the expression of the OPN and Col, where gene expression was highest in nHA followed by nHA/E30 and nHA/E50. The bioactive glass fibers were synthesized in the shortest time and showed osteogenic properties. These materials have the potential for use in bone tissue engineering, dental prosthesis, and tooth restoration.
