Dental erosion is a public health problem as it may affect various age groups and gender. It may lead to dentin hypersensitivity and eventually pulpal exposure if the erosion is severe and not treated which causes pain. Therefore, the study was done to find the association of gender with dental erosion. A retrospective study was conducted using University hospital patient records from July 2019 - March 2020. A total of 149 case sheets were reviewed. The data variables such as socio-demographic data, presence of dental erosion and number of teeth involved with dental erosion were retrieved and analyzed. Results were present with frequency distribution and chi-square test for association. Dental erosion was prevalent in males (64.4%) than females (35.6%). The age range of the patients included in the study was 21-80 years old out of which 21-40 years (14.8%), 41-60 years (57%) and 61-80 years (28.2%). Erosion in maxillary teeth involving 0-5 (85.8%) was the highest followed by 6-10 (14.1%) and erosion in mandibular teeth involving 0-5 (87.9%) was the highest followed by 6-10 (11.4%) and 11-15 (0.7%). There was no statistically significant association between gender, age with dental erosion in maxillary and mandibular teeth (p>0.05). Within the limitations of the study, it can be concluded that dental erosion was prevalent in males of early 60’s and there was no association between gender, age with dental erosion in maxillary and mandibular teeth.
