Quantitative Estimation of Yeast on Maxillary Denture in Patients with Denture Stomatitis and the Effect of Chlorhexidine Gluconate in Reduction of Yeast

Denture stomatitis is a condition associated with wearing of a denture. The predisposing factor leading to denture stomatitis could be poor oral hygiene, ill-fitting denture and relief areas. Around 30 patients with denture stomatitis were advised to rinse with chlorhexidine gluconate mouthwash for 14 days and were directed to immerse the upper denture in the chlorhexidine solution for 8 hours. The samples were collected by scraping maxillary denture in saline at three intervals, prior to, at the end of 24 hours and after 14 days of treatment, then were inoculated and quantitative estimation of the yeast growth on Sabouraud′s dextrose agar plate was done. It was observed that after a period of 14 days, there was a reduction in the growth of yeast and also improvement in the clinical picture of the oral mucos

Colour Stability of Two Different Denture Base Resins and the Efficacy of Two Denture Cleansing Agents after Tea and Coffee Staining: An In-vitro Study

Introduction: In dentistry, colour is one of the most important dimensions of aesthetics. Due to the diverse food habits in India, stains accumulate on dentures. Various denture cleansing agents such as Fittydent and Clinsodent are widely used, emphasising the importance of patient oral hygiene. Aim: To evaluate the colour stability of heat-cure activated acrylic denture base resins {Dental Products of India (DPI) and Trevalon} after staining with tea and coffee, subsequently treated with Clinsodent, Fittydent, and distilled water (control group) as cleansing agents. Materials and Methods: This in-vitro study was conducted at Swargiya Dadasaheb Kalmegh Smruti Dental College and Hospital, Nagpur, in the Department of Prosthodontics, Crown and Bridge, and Implantology in collaboration with Indorama, Nagpur, Maharashtra, India, over a period of approximately 90 days (August-October 2017). Total 120 samples were prepared in-vitro study using custom-made brass metal discs measuring 10 mm by 2 mm. Trevalon and DPI heat-cure acrylic denture base resins were used for sample preparation. Baseline colour stability values were established after immersing the samples in distilled water at 37°C for 24 hours. The samples were then stained for eight hours, followed by immersion in different cleansing agents and distilled water for 12 hours. This process was repeated every 24 hours for 60 days, with the staining and cleansing agents replenished daily. Colour measurements were taken at baseline, 15th, 30th, 45th, and 60th days. Statistical analysis involved t-tests and one-way Analysis of Variance (ANOVA). Results: The DPI denture base resin exhibited a highly significant ΔE (change in energy) at 45 days (p=0.0001), while Trevalon showed significance at 60 days (p=0.0079). The difference in means was statistically significant using t-tests for independent samples, and the variance-measure analysis indicated statistical significance in the means of ΔE. The comparison of the three cleansing agents at 60 days was statistically obtained using one-way ANOVA. Conclusion: Dental Products of India (DPI) showed more colour variation than Trevalon. Tea showed a higher staining than coffee. Staining intensity increased over time, peaking at 45 days and stabilising thereafter. Clinsodent is better than Fittydent in removing stains

Student apathy for classroom learning and need of repositioning in present andragogy in Indian dental schools

Abstract Background In the world of technology, when today's student is approaching the on-line /distance learning in the open universities and doing on-line self-assessment, the classroom learning is vanishing slowly. Globally, teachers are taking efforts to improve the pedagogy by implementing effective methods to retain the classroom teaching and student attendance. The present study aims at shedding some light on the need of changing the adult education strategies (andragogy), which can effectively improve the student attendance for lectures. Methods It is an observational study, and the conceptual framework of it is based on beliefs, opinions and personal experiences of the respondents. Triangulation method is used for collecting the data. The data is achieved from three groups of concerned population who could provide valid results to support the study. It is collected by interviewing 10 senior faculty members who are/were the 'education experts' in the universities, while the main concerned groups of present educational stream, i.e. 'institution-teachers' and the 'students', were given questionnaires. 570 teacher respondents and 200 student respondents are the main participants of this study. Results As per data, it has been observed that senior faculty (90%) and students (93.25%) feel need of student motivation more than the institutional teachers (52.44%). P-values were obtained using Chi-Square test for testing the significance of difference between agreement and disagreement for a specific question. Conclusions In India, Universities have already sensed the need of 'teacher development programmes'. But teachers in dental colleges, demand more efforts to be taken by universities and managements in this regard and expect better educational policies to give them accessibility to prove themselves.</p
