时间因素对口腔医生骨骼肌肉疼痛的影响

The investigation and analysis of the musculoskeletal pain among dentists with different time factors.

目的了解不同从业时间、每日工作时长、连续工作天数等时间因素对口腔医生骨骼肌肉系统疼痛的影响，并对其危险因素进行分析。方法采用问卷调查法，对四川大学华西口腔医院177名口腔医生进行调查。由双人录入数据，统计并比较口腔医生骨骼肌肉系统的疼痛情况。结果被调查口腔医生中，工作20～30年者疼痛现惠率最高，工作1年内的口腔医生疼痛现惠率最低。在颈部，工作30年以上者的疼痛现患率高于工作1年以内和1—10年者；在肩背部，工作20～30年的口腔医生疼痛现患率高于工作1年以内者，均有统计学意义。结论从业时间20年以上的口腔医生颈部与肩背部骨骼肌肉系统疼痛的现患率更高。更长的从业时间是骨骼肌肉系统疼痛发生的危险因素。
