As per the information obtained from the Deputy Director of Pre-University Education, Mysore, there were 15 PUCs distributed in five sectors in Mysore city. By using stratified simple random sampling, PUCs were selected from each sector by lottery method. For a population of 15,000 students, with a confidence level of 95% and a confidence interval of 5, the minimum sample size required was 375. However, the researcher studied 1000 students for higher accuracy. From each sector, 200 students were selected randomly to make up the sample size of 1000. Ethical clearance was obtained from the ethical committee of JSS Dental College and Hospital, Mysore.
