본 연구는 치석제거 실습수업을 하는 치위생학과 학생들을 대상으로 실습 전·후의 손의 근력, 파지력, 민첩성 변화를 측정하고 비교 분석하여, 수근관 증후군을 예방하기 위한 기초자료를 제공하고자 하였다. 치위생학과 4학년 재학생 중 손의 해부학적 구조, 근력, 파지력 및 감각에 이상이 없는 15명을 대상으로 치석제거 실습 전과 실습 후에 손의 근력, 파지력, 민첩성을 측정하였다. 수집된 자료는 PASW Statistics 18.0(SPSS) 통계프로그램을 활용하여 처리하였다. 연구결과 손의 근력과 파지력은 실습 전과 비교하여 실습 후에 감소하였다. 손의 민첩성은 실습 전과 비교하여 실습 후에 증가하였다. 이러한 결과를 통해 스케일링 동작 시 피로를 줄 수 있는 손동작을 자제하고, 스케일링 전후로 스트레칭 등 손의 힘을 기르는 예방운동의 개발이 필요할 것으로 사료된다.

Objectives : The purpose of the research is to measure Dental Hygiene students' level of musculoskeletal pain before and after receiving scaling training which involves repetitive operations and examine effects the operations have on the students' grip and pinch strength. Methods : 15 subjects in Dental Hygiene at Y university located in Chungbuk were tested on November 2, 2011. Results : 12 students had a musculoskeletal pain before receiving scaling training. However, all the 15 students had a musculoskeletal pain after the training. Body part the largest number of the students complained of the pain on was shoulders(37.9%) followed by neck(20.8%), waist(13.9%), wrists(10.3%), then back(6.9%) before receiving the training. Then the result showed that shoulders are where the largest number of students(24.1%) felt the pain, followed by neck(17.2%), wrists and fingers(13.8%), waist(12.1%), back and lower arms(6.9%), then palms(5.2%) after the training. Visual Analogue Scale(VAS) increased to $6.35{\pm}2.09$ after receiving the training from $3.31{\pm}3.38$ and this shows statistically significant difference(p<.001). Upon inspection, average grip strength decreased to $23.23{\pm}5.79kg$ from $25.00{\pm}4.51kg$ after receiving the training and this shows statistically significant difference(p<.05). Key pinch was the strongest among the three pinch strengths followed by tripod pinch then tip pinch. Average of all the three pinch strengths showed to have statistically significant difference before and after the training(p<.05); Tip pinch from $6.53{\pm}1.36$ to $5.87{\pm}1.3$, key pinch from $13.47{\pm}2.5$ to $12.53{\pm}2.30$, and tripod pinch from $9.27{\pm}3.04$ to $8.03{\pm}2.72$. Conclusions : The result showed that scaling training has effects on Dental Hygiene students' musculoskeletal subjective symptoms and their grip and pinch strength changes after receiving the training.

Purpose: We evaluated the physical stress and pain to the musculoskeletal system of a dental practitioner when engaging in a dental scaling training exercise to prevent the development of musculoskeletal injuries. Methods: The 18 female (average age: 21$\pm$1 years) subjects were voluntarily picked from a group of juniors who have completed a one-and-a-half year training course that includes training exercises on the dentiform and on live subjects (other trainees). The test is done by measuring pain, activity, grip strength, and finger dexterity for each subject's hand and wrist. Before the test all subjects were confirmed to be right-handed and were informed of the study and its objective. Measuring was done before and after each subject performed dental scaling for one hour using the scaler and the curet. Results: Pain levels increased for both hand and shoulders, but hand pain was often greater than shoulder pain. Grip strength significantly declined in the right hand but not the left. For joint mobility, the flexion and the extension for the shoulder joint did not change; but the range of motion for both wrist joints significantly increased. For the dexterity test, both hands showed increased dexterity after the exercise. Conclusion: Dental scaling can affect the shoulders and wrists/hands. Therefore, a musculoskeletal injury prevention program for dental practitioners, which may include encouraging them to assume correct body posture when at work, must be sought. This study evaluated only the shoulders, wrists, and hands; but future studies should include areas such as the cervical area, the back, and the lower limbs.
