Self-esteem is very crucial in one’s emotional well-being. This study was based on the investigation of the relationship between the body image and self-esteem undergraduate dental students in Chennai. In this study, a total of 200 students was selected by convenience sampling from undergraduate dental students between the age group of 17 to 23 years, who study in Chennai through online google form questionnaire. Two sets of questionnaires were used: Body Shape Questionnaire[BSQ]-16B and Rosenberg self-esteem scale. In BSQ-16B, the scale ranges from never to always and in Rosenberg self-esteem questionnaire, which was based on the Likert Scale, ranging from strongly agree to strongly disagree. SPSS version 22 [IBM cooperative] software was used for statistical analysis to evaluate the results. It indicated that the correlation coefficient value (r value) between the BSQ scores and the Rosenberg self-esteem scale scores was -0.373 that is a negative relationship between the BSQ scores and the Rosenberg self-esteem scale scores. As this study was done in late adolescence during their undergraduate study period more surveys with middle-aged group people and / or elderly subjects could thus possibly add up a remarkable quantity of knowledge to the outcomes of this project
