Work-related musculoskeletal disorders are commonly observed across various occupational groups.
The aim of this study was to evaluate the relationships between hand grip and pinch strength, body composition, pain threshold, and anxiety levels in dentists.
The study included 49 dentists working at Sakarya Oral and Dental Health Hospital. Participants' grip strength, including pinch and gross grip, was assessed using the Jamar hand dynamometer, while the muscle strength of the forearm flexor and extensor muscles was measured with a handheld dynamometer. Anxiety levels were evaluated using the Beck Anxiety Inventory, and pain threshold was assessed using an algometer.
A positive and significant correlation was found between body mass index (BMI) and dominant and non-dominant hand grip strength (r = 0.485, p = 0.003; r = 0.501, p = 0.002). BMI also showed a strong relationship with dominant and non-dominant finger strength (r = 0.511, p < 0.001; r = 0.557, p < 0.001). A negative correlation was found between Beck Anxiety Score and physical strength parameters, especially non-dominant hand grip strength (r = 0.619, p = 0.005) and dominant hand grip strength (r = - 0.512, p = 0.025) and anxiety levels. Significant positive correlations were found between pain threshold and physical strength parameters, especially non-dominant wrist extensor strength (r = 0.283, p = 0.049) and dominant hand grip strength (r = 0.408, p = 0.015) which were found to increase pain threshold.
Physical and psychological factors have an impact on occupational performance, especially in occupations that require prolonged use of the hands and wrists, such as dentistry.

工作相关的肌肉骨骼疾病在各个职业群体中都很常见。
本研究旨在评估牙医的握力和捏力、身体成分、疼痛阈值与焦虑水平之间的关系。
该研究纳入了在萨卡里亚口腔和牙科健康医院工作的49名牙医。使用Jamar握力计评估参与者的握力，包括捏力和总握力，同时使用手持测力计测量前臂屈肌和伸肌的肌肉力量。使用贝克焦虑量表评估焦虑水平，使用痛觉计评估疼痛阈值。
体重指数（BMI）与优势手和非优势手握力之间存在显著正相关（r = 0.485，p = 0.003；r = 0.501，p = 0.002）。BMI与优势手指和非优势手指力量也有很强的关系（r = 0.511，p < 0.001；r = 0.557，p < 0.001）。贝克焦虑评分与体力参数之间存在负相关，尤其是非优势手握力（r = 0.619，p = 0.005）、优势手握力（r = -0.512，p = 0.025）与焦虑水平。疼痛阈值与体力参数之间存在显著正相关，尤其是非优势手腕伸肌力量（r = 0.283，p = 0.049）和优势手握力（r = 0.408，p = 0.015），发现这些参数会提高疼痛阈值。
身体和心理因素会影响职业表现，尤其是在牙科等需要长时间使用手和手腕的职业中。
本研究已在NCT06721117（http://clinicaltrials.gov）进行前瞻性注册。
