Good oral health can be achieved by preventive dental behaviours such as regular dental visits as well as practising adequate selfcare by means of proper and frequent tooth brushing methods. OBJECTIVES: To correlate the influence of socio-economic parameters (occupation, education and income) according to modified Kuppuswamy's scale on preventive dental behaviours such as frequency of dental visits and tooth brushing with paste.
METHODS: A self-administered questionnaire based cross sectional survey was conducted to determine the influence of socio-economic status on Dental visits and frequency of tooth brushing in patients visiting the O.P.D ( Out Patient Department)at I.T.S Dental College, Greater Noida. A total of 327 patients from 18 to 74 years were included from both the genders. A fifteen item closed ended questionnaire was prepared, which had information regarding the Chief complaint along with Age, Gender, Socioeconomic Status, intervals of dental visits and frequency of brushing. Kuppuswamy's socioeconomic classification, which includes monthly income, education level and occupation, was used to classify the socioeconomic status (SES) of the patients. RESULTS:There was no statistically significant difference reported between various levels of education, socio-economic status and gender when correlated with the frequency of dental visits. However, the results show that with increase in the level of education and socio-economic status the frequency of tooth brushing was positively correlated. CONCLUSION: The results of our study suggest that groups with low education and socio-economic status are important targets to enhance dental preventive behaviours.
With advent advancement in All Ceramic System available, the metal ceramic restorations are still widely used. For any metal ceramic restoration to survive the masticatory load, environment, and time exponential stress in form of tensile, compressive and shear in the oral cavity, a strong bond is required between the cast metal coping and the porcelain. The aim of this study was to make a comparison between the relative adherence of porcelain (VITA VMK68) with two precious and two non precious metal ceramic alloys using ESCA. 20 cast plates 13mmX13mmX1mm in dimension, 5 High Palladium Alloy (Neopal), 5 Silver Palladium (Degustar-F), 5 Nickel Chrome (Remanium CS), 5 Cobalt Chrome (Remanium2000), were prepared according to ADA specifications, porcelain 1mm thick was applied. These cast plates were subjected to bi-axial flexure of the specimen in a constant strain in a special apparatus loaded on an Instron machine and compressive load was applied at a stroke rate of 0.25 mm/minute. This resulted in adhesive fracture of the porcelain. The area of retained porcelain after fracture from a surface of the cast plate was calculated by using ESCA instrument. The value of relative adherence of Vita VMK 68 to all the four alloy groups was calculated as numbers of squares occupied by silica peak in ESCA reading chart. The value obtained was statistically analyzed using one way variance analysis (ANOVA). From the statistical analysis it was found the value of relative adherence of two precious alloys is varying and is statistically significant.The value of relative adherence of two non-precious alloys varying and is statistically significant. The overall comparison of relative adherence of precious alloys with that of non precious alloys shows appreciable variation between them. When these values are subjected to statistical analysis, they are statistically highly significant.
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.
