A cross sectional comparative survey was conducted among battery chargers and automobile mechanics in Ibadan to determine the effect of exposure of acid in form of solution or fumes on tooth enamel wear one hundred and five subjects were recruited and examined for erosion. This number comprised 67 automechanics and apprentices and 38 battery chargers and their apprentices. Other groups of automobile workers sharing the workshops were excluded from the study. All respondents aged between 11 and 68 years of age. Verbal informed consent was taken from all the subjects. One thousand and one hundred teeth were examined using the upper and lower central sextants. One hundred and sixty teeth were found to be missing. The teeth examined comprised 712 teeth of automechanics (88.55%) and 388 teeth of battery chargers (85.08%). Out of the 712 teeth of automechanics, only 23 teeth (3.2%) showed evidence of tooth wear whereas in the battery chargers group, 159 teeth out of 388 teeth (41%) had tooth wear. (P < 0.05). The battery charger group also showed a higher percentage of missing teeth, (14.9%) as against 11.44% of the automechanic group (P > 0.05). This study has shown that battery chargers are subjected to occupational hazard of exposure to highly erosive acids and fumes. Prevention through oral health education targeted at this group of subjects and early diagnosis are very important.

在伊巴丹对电池充电器操作人员和汽车修理工进行了一项横断面比较调查，以确定溶液或烟雾形式的酸暴露对牙釉质磨损的影响。招募了105名受试者并检查其牙齿侵蚀情况。这105人包括67名汽车修理工及其学徒和38名电池充电器操作人员及其学徒。在车间工作的其他汽车工人组被排除在研究之外。所有受访者年龄在11至68岁之间。所有受试者均获得了口头知情同意。使用上下中六分仪检查了1100颗牙齿。发现160颗牙齿缺失。检查的牙齿包括712颗汽车修理工的牙齿（88.55%）和388颗电池充电器操作人员的牙齿（85.08%）。在712颗汽车修理工的牙齿中，只有23颗（3.2%）有牙齿磨损迹象，而在电池充电器操作人员组中，388颗牙齿中有159颗（41%）有牙齿磨损。（P<0.05）。电池充电器操作人员组的牙齿缺失百分比也更高，为（14.9%），而汽车修理工组为11.44%（P>0.05）。这项研究表明，电池充电器操作人员面临接触高腐蚀性酸和烟雾的职业危害。针对这组受试者进行口腔健康教育和早期诊断的预防措施非常重要。
