A cross-sectional study on oral health status of battery factory workers in Chennai city.

Abstract

Aim and Objective:Some occupational exposures are associated with oral changes in both hard and soft tissues. Presence of oral lesions can interfere with speech, swallowing, and general health of a patient. The present cross-sectional study was conducted to evaluate the oral health status of battery factory workers in Chennai city.Materials and Methods:A total of 600 subjects were selected in battery factory out of 3500 workers using statistical sample selection formula 4pq/l2 and divided into study and control groups based on acid exposure. The data were recorded on a modified World Health Organization 1997 pro forma. The data were evaluated using Chi-square test and Mann–Whitney U-test.Materials and Methods:A total of 600 subjects were selected in battery factory out of 3500 workers using statistical sample selection formula 4pq/l2 and divided into study and control groups based on acid exposure. The data were recorded on a modified World Health Organization 1997 pro forma. The data were evaluated using Chi-square test and Mann–Whitney U-test.Results:Oral symptoms such as disturbed taste, dry mouth, oral ulcers, and foul breath were statistically significant between the groups (<0.001). Dental erosion was statistically significant with the duration of working years. Dental erosion was significant among study group compared to control (0.001).Conclusion:The present study showed that selected samples had various oral conditions due to exposure to acids from battery. It was observed that oral health problems were directly related to the duration of acid exposure in the study group. Implementing exhaust ventilation and monitoring the devices help in reducing the acid exposure. Implementation of oral hygiene education and nutritional supplementation helps in improving their oral health.
