A greater understanding of impact of occupational dental erosion on oral health-related quality of life (OHRQoL) will sensitize both employee and employers to adopt strict protective measures for oral health. The research aimed to determine the relationship between occupational dental erosion and OHRQoL among battery and other factory workers in Bengaluru, India.
This cross-sectional comparative study enrolled a total of 400 workers. Structured proforma assessed information on sociodemographic details, oral hygiene practices, adverse oral habits, and work-related practices. OHRQoL was determined using oral health impact profile-14 (OHIP-14). Dental erosion was measured using Smith and Knight's tooth wear index modified by Millward . 1994 scoring system independent -test, Mann-Whitney U-test and Spearman's correlation was performed. < 0.05 was considered statistically significant.
The mean age of the participants in the study and control groups was 43.11 ± 8.02 and 45.93 ± 6.16 years, respectively. Less than half of the participants in the study group had positive behavioral work practice. The prevalence and severity of dental erosion was significantly higher in study group (39.5%) than control group (11.5%). Mean OHIP-14 score was significantly lower in study group (23.88 ± 0.88) than control group (26.06 ± 9.67). Dental erosion significantly correlated with work experience and OHIP-14.
The findings highlight the impact of occupational dental erosion on OHRQoL. Measures to enhance occupational safety thereby reducing exposure to occupational hazards are needed.
深入了解职业性牙齿侵蚀对口腔健康相关生活质量（OHRQoL）的影响，将使员工和雇主都更加重视采取严格的口腔健康保护措施。本研究旨在确定印度班加罗尔电池厂和其他工厂工人中职业性牙齿侵蚀与OHRQoL之间的关系。
这项横断面比较研究共纳入400名工人。采用结构化表格评估社会人口学细节、口腔卫生习惯、不良口腔习惯和与工作相关的习惯等信息。使用口腔健康影响程度量表-14（OHIP-14）来确定OHRQoL。采用经米尔沃德修改的史密斯和奈特牙齿磨损指数测量牙齿侵蚀情况。进行1994评分系统独立样本t检验、曼-惠特尼U检验和斯皮尔曼相关性分析。P<0.05被认为具有统计学意义。
研究组和对照组参与者的平均年龄分别为43.11±8.02岁和45.93±6.16岁。研究组中不到一半的参与者有积极的工作行为习惯。研究组牙齿侵蚀的患病率和严重程度（39.5%）显著高于对照组（11.5%）。研究组的平均OHIP-14得分（23.88±0.88）显著低于对照组（26.06±9.67）。牙齿侵蚀与工作经验和OHIP-14显著相关。
研究结果突出了职业性牙齿侵蚀对OHRQoL的影响。需要采取措施加强职业安全，从而减少职业危害暴露。
