The Relation between Risk Factors and Musculoskeletal Impairment in Dental Students: a Preliminary Study

Abstract

Musculoskeletal disorders are common among dentists, 80% of the measurement results using the instrument of Body Discomfort Map and Brief Survey in Faculty of Dentistry University of Indonesia (FKG UI) showed that musculoskeletal disorders (MSD) mainly occur in the neck, shoulder, forearm, hand and back. MSD are the most common type of occupational dental diseases in Indonesia. Objectives: To know the risk factors associated with MSD in students in FKG UI. Methods: This type of observational study with cross-sectional design of the entire profession students who work in clinic FKG UI. Examination of MSD was using Cornell MSD questionnaires (CMDQ) and risk factors were measured using a questionnaire with closed questions and Diagnostic Stress Survey. All data collected were analyzed statistically using chi-square test and logistic regression. Results: A significant relationship between repetitive movements of factors, awkward bending and twisting with musculoskeletal disorders (p<0.05) and the presence of a significant association between work stress factors with musculoskeletal disorders (p<0.001). Then the logistic regression results indicate that a variable effect on musculoskeletal disorders is a movement in the work (OR 5.01; CI 90%) and stress of work (OR 7.47; CI 90%). Conclusion: In this study we can conclude that the relationship between the working and movement of factors of work stress on musculoskeletal disorders. ABSTRAK Hubungan faktor-faktor risiko dan kelainan muskuloskeletal pada mahasiswa profesi kedokteran gigi: studi pendahuluan. Gangguan muskuloskeletal banyak terjadi pada dokter gigi, 80% dari hasil pengukuran menggunakan instrumen Body Discomfort Map dan Brief Survey di FKG UI memperlihatkan bahwa gangguan muskuloskeletal terutama terjadi pada leher, bahu, lengan bawah, tangan dan punggung. Gangguan muskuloskeletal merupakan penyakit terbanyak dari penyakit akibat kerja di Indonesia. Tujuan: Mengetahui faktor-faktor risiko yang berhubungan dengan gangguan muskuloskeletal pada mahasiswa tingkat profesi yang kerja praktik di FKG UI. Metode: Jenis penelitian observasional dengan disain potong lintang terhadap seluruh mahasiswa profesi yang kerja praktik di klinik FKG UI. Pemeriksaan gangguan muskuloskeletal menggunakan instrumen Cornell Musculoskeletal Discomfort Questionnaires (CMDQ) dan faktor-faktor risiko diukur menggunakan kuesioner dengan pertanyaan tertutup dan survei diagnostik stres. Seluruh data yang terkumpul di analisis statistik menggunakan chi-square dan uji regresi logistik. Hasil: Adanya hubungan bermakna antara faktor gerakan dalam bekerja (gerak repetitif, janggal membungkuk dan memutar) dengan gangguan muskuloskeletal (p<0,05) dan adanya hubungan yang bermakna antara faktor lingkungan (stressor kerja) dengan gangguan muskuloskeletal (p<0,001). Kemudian pada hasil regresi logistik menunjukkan variabel yang dominan mempengaruhi terjadinya gangguan muskuloskeletal adalah gerakan dalam bekerja (OR 5,01 CI 90%) dan stres kerja (OR 7,47 CI 90%). Simpulan: Pada penelitian ini dapat ...

Correlation between working positions and lactic acid levels with musculoskeletal complaints among dentists

“…2 From these data, it can be said that the prevalences of musculoskeletal disorders are high among dentists in some countries. In Indonesia, the prevalence of musculoskeletal disorders is still unknown since there have been no data on the prevalence of musculoskeletal disorders among dentists in Indonesia, especially in the city of Surabaya.…”

“…However, based on screening results conducted in Faculty of Dentistry, Universitas Indonesia using Discomfort Body Map and Brief Survey instruments, there are 80% dentists working in clinics suffering from MSD mainly on neck, shoulders, forearms, hands, and back. 2 One of factors causing musculoskeletal syndrome suffered by dentists is that they care more with the comfort for patients treated, but less attention to their comfort when caring for patients. Dentists consider more on the need to move toward their patients rather than to adjust the seating position of their patients on dental chair.…”

Correlation between working position of dentists and malondialdehyde concentration with musculoskeletal complaints

“…2 In Indonesia, the number of incidents is unidentified since there has been no data provided about the prevalence of musculoskeletal complained by dentists in Indonesia According to the result of screening conducted at Faculty of Dentistry, Universitas Indonesia using body discomfort map and brief survey as instruments, which found that 80% of dentists who work in the clinic experience musculoskeletal disorder, particularly on neck, shoulders, forearms, upper arms, hands and back. 2 One of the causes of musculoskeletal syndrome experienced by dentists is because the dentists assume that they are the one who should make moves to get close to the patients rather than they should arrange patient's sitting position on the dental chair. Most musculoskeletal disorders among dentists occur since the dentists are positioning their body unconsciously that do not support their movement during treating the patients.…”

Correlation between Age and Period of Working with the Musculoskeletal Disorders Complaints on Palm Farmers in Pt. X

“…World Health Organization (WHO) define the MSDs is the disturbance of the muscles, tendons, joints, vertebrae, peripheral nerves and vascular system occur suddenly or gradually and acute and chronic (Wijaya et al, 2011). Adverse impact of the disturbance will result in reduced skills to carry out the work, reduced work productivity and increased health care costs.…”
