Kebanyakan dokter gigi tidak menyadari pentingnya manfaat sistem ergonomi dengan posisi yang baik saat merawat pasien. Gangguan muskuloskeletal adalah salah satu yang jelas sebagai hazard. Saat melakukan pencabutan gigi, kadang-kadang dokter gigi membungkuk ke arah pasien, bergerak secara mendadak, memutar tubuh dari satu sisi ke sisi yang lain. Seluruh gerakan tersebut dilakukan berkali-kali dalam jangka waktu yang panjang sehingga sering mengalami rasa tidak nyaman dan sakit di daerah leher, bahu, tulang punggung serta pergelangan tangan. Penelitian ini meninjau faktor-faktor risiko ergonomi dokter gigi terhadap keluhan Musculoskeletal Disorders pada aktivitas pencabutan dengan jenis potong lintang melalui pendekatan observasional.Hasil penelitian 74,3% tindakan pencabutan gigi menimbulkan gangguan secara fisik, 61,4% melakukan gerakan berulang punggung membengkok ke depan, belakang atau ke samping , 35,7% melakukan gerakan berulang punggung membengkok dan memutar secara simultan dalam melakukan tindakan dan melalui Nordic Map Quesioner didapat frekuensi timbulnya keluhan pada daerah sekitar leher 38,6%. Intensitas keluhan rasa nyeri, sakit dan ketidaknyamanan akibat kerja yang cukup mengganggu aktifitas kerja dikemukakan pada bagian kaki kanan 61,4 %, bahu kanan atas sebanyak 48,6 %, pada bagian pergelangan tangan kanan 40% serta pada leher sebanyak 47,1%.Hasil akhir yang didapat melalui observasi dengan pengukuran metode OWAS (Ovako Working Posture Analysis System) di dapatkan kategori 2 dimana postur kerja memiliki beberapa efek yang berbahaya bagi system musculoskeletal serta diperlukan tindakan untuk perubahan posisi kerja pada perencanaan yang akan datang.
Most dentists do not realize the importance of the benefits ergonomics system with a good position when treating patients. Musculoskeletal disorders is an obvious one as a hazard. When performing tooth extraction, dentists sometimes leaned toward the patient, a sudden move, rotate the body from one side to the other. The whole movement is done many times in the long term so often experience discomfort and pain in the neck, shoulder, spine and wrist. This study reviewed the dentist ergonomic risk factors from Musculoskeletal Disorders in the type of extraction activity through cross-sectional observational approach.74.3% of research results to extract a tooth cause physical disorders, 61.4% perform repetitive motions backs bent forward, backward or sideways, 35.7% perform repetitive movements back bend and rotate simultaneously in action and through Nordic Map questioner obtained the frequency of complaints in the area around the neck of 38.6%. complaints of pain intensity, pain and discomfort caused by work is quite disturbing work activities presented in section 61.4% right foot, right shoulder up 48.6%, 40% on the right wrist and the neck 47.1%.The final result is obtained through observations with measurements of methods OWAS (Ovako Working Posture Analysis System) in which the working posture level 2 has some effects that are harmful to the musculoskeletal system and the necessary action to change the position of the work on the future planing.
