The aim of the investigation was to study the frequency of pain, ache and discomfort in the musculoskeletal system among dentists, above all concerning headache, cervical and shoulder pain and further, to find possible correlations between these symptoms and various working positions and different working actions. A questionnaire was answered by 359 dentists (90.8%). Of those who answered the questionnaire 72% had pain and discomfort from either the neck, shoulders or headaches. Only 60 dentists had no pain or discomfort. Concerning the male dentists, the investigation revealed that younger dentists had pain and discomfort in the neck, shoulders and headaches to a greater extent than the older dentists. Younger female dentists had a significantly higher frequency of pain and discomfort in the neck and headaches than older colleagues. The results showed that dentist who positioned the patient carefully so that a direct view gained had a significantly lower frequency of headaches. Of the 359 dentists 55% mostly used the mirror to facilitate a direct view. From the answers it was clear that those dentists who did not have discomfort in the upper locomotor system used the mirror more often than those who did suffer discomfort.
该调查的目的是研究牙医肌肉骨骼系统中疼痛、酸痛和不适的发生频率，尤其是头痛、颈部和肩部疼痛，并进一步找出这些症状与各种工作姿势和不同工作动作之间可能存在的关联。359名牙医（90.8%）回答了一份问卷。在回答问卷的人中，72%的人有颈部、肩部疼痛或头痛不适。只有60名牙医没有疼痛或不适。关于男性牙医，调查显示年轻牙医在颈部、肩部疼痛和头痛方面比年长牙医更为严重。年轻女性牙医颈部疼痛和头痛的发生频率明显高于年长同事。结果表明，仔细摆放患者位置以便获得直接视野的牙医头痛发生频率明显较低。在359名牙医中，55%的人主要使用镜子来辅助获得直接视野。从答案中可以明显看出，上运动系统没有不适的牙医比有不适的牙医更经常使用镜子。
