Background:Diabetes mellitus is a metabolic disease leading to abnormal fat, carbohydrate and protein metabolism. Reduced salivary flow rate caused by hyperglycemia is characteristic mainly for periods of poor metabolic control of diabetes, thereby facilitating the growth of aciduric bacteria and caries-lesion development. The objective of our study was to evaluate the effects of diabetes mellitus on dental caries micro-organisms responsible for caries.Materials and Methods:This study was carried out on 60 subjects consisting of 2 groups. The Group A (study group) consisted of 30 subjects with diabetes mellitus and dental caries, and the Group B (control group) consisted of 30 subjects with dental caries but no systemic disease. DFS/dfs index in all subjects was evaluated and compared. Unstimulated salivary flow was collected and levels of Streptococcus mutans were analyzed.Results:It was found that the fasting blood sugar in Group A subjects because of which there was increased streptococcus mutans count and hence high caries index as compared to that of Group B.Conclusion:From our study, we could conclude that with increased age, blood sugar levels, DMFT values, dental caries increases in diabetics than in normal (control) subjects and therefore relationship does exist between diabetis mellitus, oral microbiota and dental caries.
Introduction: As a part of education reforms Medical Council of India has introduced early clinical exposure (ECE) as an important intervention in Medical teaching. It is stated in the literature, ECE helps to relieve stress of the students pertaining to patient handling, developing real-time clinical reasoning ability, communication skills, professional attitude, and patient empathy. With this view, this study was planned to assess effectiveness of early clinical exposure in improving attitude and professional skills in the current Indian medical education set up. Methods: This cross-sectional study was carried out amongst 820 students for three years duration. Students were randomly divided into two groups viz. ECE exposed group (Group A) and Traditional teaching exposed group (Group B). We conducted periodical sessions (Each duration: 60 minutes). We used a validated 10-point questionnaire for feedback collection. Results: Using perception-based 10-point questionnaire based on Likert scale we found, 93.21% of students strongly agreed that the method of ECE teaching aroused interest in learning. 86.03% of students strongly agreed that the method of ECE teaching technique helped in better retention of topic. 89.91% of students strongly agreed that the method of ECE teaching imparts better clinical context. 92.75% of students strongly agreed that the method of ECE teaching allows better assimilation of knowledge gained during learning. With ECE-based teaching 87.42% of students found highly satisfied while 81.22% of students found highly competent about the knowledge and skills thus acquired via this teaching methodology. 95.11% of students liked ECE teaching methodology and these students enjoyed it a lot and with interest. Conclusion: This study concluded that early clinical exposure is the most important teaching tool in improving attitude and professional skills in the current Indian medical education set up.
Background: Exposure to light from viewing devices at night disturbs the circadian rhythm, especially sleep. The study aimed to assess (a) extent to which smart phones are used by medical undergraduate students during bedtime and to find their quality of sleep (b) the association of quality of sleep and cell phone variables. Methods: A cross sectional observational study was conducted among 450 medical undergraduate students. The participants completed Pittsburgh Sleep Quality Index (PSQI) questionnaire and a validated semi structured questionnaire consisting of demographic details and cell phone variables. Results: By dividing the subjects into three groups according to their usage (Group I <1 hour, Group II 1 to 2 hours, Group III >2 hours), Group III respondents had significant prolonged sleep latency, reduced sleep duration, sleep inefficiency and daytime sleep disturbances ( P < 0.05). Lack of awareness about night shift mode, lying posture use while using phone during bedtime correlated with poor quality sleep ( P < 0.05). Conclusions: Awareness about the negative impact of evening exposure to viewing devices on sleep and health should be emphasized.
Background:Diabetes mellitus is the fifth most common chronic condition and the sixth most frequent cause of death among the elderly. The objective of this research was to develop a new method for diabetes diagnosis by analysis of the glycogen content of the oral epithelial cells.Materials and Methods:Ten control subjects and ten diabetic patients (study group) were taken, four oral smears for both control and study group from the buccal mucosa were taken and stained with hematoxylin and eosin stain, Papanicolaou (PAP) stain, periodic acid Schiff (PAS) stain and PAS-Diastase (PAS-D) stain.Results:The results showed that in the diabetic group: (i) The epithelial cells stained with PAP stain exhibited figures of binucleation and occasional karyorrhexis, (ii) the epithelial cells treated with PAS-D showed that glycogen containing cells did not take up the stain as compared to the other cells.Conclusion:The results associated with clinical and histological observations suggest that diabetes mellitus can produce alterations of oral epithelial cells as well as in their glycogen content.
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.
