The effect of cement and stone dust on teeth was explored in a cross-sectional study, using blind dental examinations. The sample consisted of 36 workers who had been exposed to to the dust and 62 control workers. Tooth surface loss was observed in 72.2 per cent of the exposed workers and in 48.4 per cent of the controls (P less than 0.03). In both the maxillae (P less than 0.001) and the mandible (P less than 0.02) the amount of tooth surface loss was greater in the exposed workers than in the controls. Both anterior and posterior teeth were affected. These findings indicate that tooth surface loss caused by work-related dust should be considered an occupational hazard.
在一项横断面研究中，通过盲法牙科检查探究了水泥和石粉对牙齿的影响。样本包括36名接触粉尘的工人和62名对照工人。在72.2%的接触工人和48.4%的对照工人中观察到牙齿表面磨损（P小于0.03）。在上颌（P小于0.001）和下颌（P小于0.02），接触工人的牙齿表面磨损量均大于对照工人。前牙和后牙均受到影响。这些发现表明，与工作相关的粉尘导致的牙齿表面磨损应被视为一种职业危害。
