To investigate the prevalence of work-related musculoskeletal disorders amongst dentists who work in public clinics in São Paulo, Brazil, to investigate their awareness of the presence of risk factors in the workplace, disability due to pain, and the influence of pain on this awareness and disability.
A cross-sectional study was conducted among 204 dentists who work in public health clinics in the northwest of São Paulo, Brazil. The data was collected through interviews, using the Nordic Questionnaire and the Work-Related Activities that May Contribute to Job-Related Pain Questionnaire. In the case of workers who reported pain, the Pain Disability Questionnaire (PDQ) and the Numeric Pain Scale were also administered. Statistical analyses were performed using SPSS 21.0.
Most dentists (81.4%) had musculoskeletal disorders, especially in the neck, shoulders and lower back. We found that the presence of symptoms in the neck (15.7%), shoulders (12.7%) and lower back (15.7%) were the major causes of absenteeism over the past 12 months. Occupational risk factors perceived as the most problematic ones were: bending or twisting the back in an awkward way, continuing to work when injured or hurt and working in the same position for long periods. Comparison between the symptomatic and asymptomatic dentists showed a statistically significant difference (p < 0.05) in the perception of occupational risk factors. The analysis of the intensity of pain and disability with PDQ in the symptomatic dentists showed an average pain intensity of 3.8. Mean scores of the PDQ total (11.46) and its dimensions - functional condition (7.1) and psychosocial condition (4.4) - suggest a moderate disability in the dental surgeons. There was a strong t correlation (r = 0.697) between pain intensity and the total score of disability caused by pain.
Pain and work-related musculoskeletal disorders interfere significantly with the dentists' lives. In the case of dental surgeons there is a significant correlation between pain intensity and disability. Int J Occup Med Environ Health 2017;30(3):367-377.
调查在巴西圣保罗公立诊所工作的牙医中与工作相关的肌肉骨骼疾病的患病率，调查他们对工作场所危险因素的认识、因疼痛导致的残疾，以及疼痛对这种认识和残疾的影响。
对在巴西圣保罗西北部公立卫生诊所工作的204名牙医进行了一项横断面研究。通过访谈收集数据，使用北欧问卷和可能导致工作相关疼痛的工作相关活动问卷。对于报告有疼痛的工人，还进行了疼痛残疾问卷（PDQ）和数字疼痛量表的评估。使用SPSS 21.0进行统计分析。
大多数牙医（81.4%）患有肌肉骨骼疾病，尤其是颈部、肩部和下背部。我们发现，颈部（15.7%）、肩部（12.7%）和下背部（15.7%）出现症状是过去12个月旷工的主要原因。被认为最成问题的职业危险因素是：以笨拙的方式弯腰或扭背、受伤时仍继续工作以及长时间保持同一姿势。有症状和无症状牙医之间在职业危险因素认知方面存在统计学显著差异（p < 0.05）。对有症状牙医的疼痛强度和使用PDQ评估的残疾情况分析显示，平均疼痛强度为3.8。PDQ总分（11.46）及其维度——功能状况（7.1）和心理社会状况（4.4）的平均得分表明牙科外科医生存在中度残疾。疼痛强度与疼痛导致的残疾总分之间存在很强的相关性（r = 0.697）。
疼痛和与工作相关的肌肉骨骼疾病严重影响牙医的生活。对于牙科外科医生来说，疼痛强度与残疾之间存在显著相关性。《国际职业医学与环境卫生杂志》2017年；30（3）：367 - 377。
