Aim:
The main purpose of the study was to learn the possible shade differences between human eye and the digital method with spectrophotometric methods.
Materials and Methods:
Fifty dental students of age groups 18–25 with maxillary right central incisor after undergoing oral prophylaxis were included in this study. Before undergoing shade selection, standardization protocol was followed. The shade of the right maxillary central incisor was determined by using the following methods: visual, spectrophotometer, and digital photography. The shades obtained by both spectrophotometer and visual methods are compared and similarly

values of digital and spectrophotometric methods were found to be statistically significant. Tooth shade selected between spectrophotometric and visual method was analyzed by using chi-square test, which shows highly significant value.
Conclusion:
It was concluded that the digital photography can be used as one of the reliable methods for shade selection in a clinical setup.
Introduction:Infection control is very important in dentistry. Both dentist and patients are at risk of communicating diseases during treatment procedures. Dental burs have been identified as a source of cross-contamination between patient and dental personnel.Aim:The present study was done to quantitatively and qualitatively assess the pathogenic contamination of dental burs used for tooth preparation and to determine the effective method of sterilization(autoclave, glass bead sterilizer, hot air oven and surgical spirit immersion) of burs used for crown preparation.Methodology:Dental burs were assessed before and after tooth preparation, also after sterilization burs were evaluated.Conclusion:Findings of our study revealed that among the experimental groups used in the present study, Autoclave and Hot air oven was found to be the relatively best method to sterilize burs. Proper cleaning and sterilization of burs should be strictly employed to prevent cross contamination in clinical practice.
Introduction:Edentulousness falls in a special category among the various conditions of dental origin. A simple estimation of the partial edentulous condition is a rough indication of the prevalence of dental diseases and success or failure of dental care.Methodology:In this study a cross sectional survey was carried out among 1000 patients of rural population in JKK Nataraja Dental College, Komarapalayam, Namakkal District, Tamilnadu, India. The aim of this study was to evaluate the epidemiological features of partial edentulous condition in the age group of 30-60 years in a rural Population based on the Kennedy classification. A pre tested questionnaire was Used in this study.Result:Chi-square test was conducted and results were obtained and P value <0.05 was considered stastically significant.Conclusion:The study revealed Kennedy Class III partially edentulous condition was more common than other conditions. There is significant correlation between lack of awareness, education and socio-economic status in relation to loss of teeth among population.
