Volume 2, Issue 3 (12-2014)
Abstract

Introduction: High prevalence of neck pain has become an important health complain among dental practitioners which is followed by reduced working performance, burnout and early retirement. The purpose of this study is to assess the relationship between individual and occupational risk factors as well as forward head posture (FHP) with dentist’s neck pain and to determine the priority of these factors in the development of the neck pain.

Material and Methods: In this cross - sectional study, 70 dentists of two dental centers in Tehran were examined with clinical testing of FHP. Individual and job characteristics were collected by means of a questionnaire. The visual analog scale (VAS) was applied in order to determine the severity of pain in various parts of the body. Spearman and Pearson correlation coefficient and multiple linear regressions were used to examine the relationship and effect of the studied variables in creating the neck pain.

Results: According to the results, neck was the most painful part of the body (66.6%). Indeed, 40 (57.1%) of participating dentists were suffering from the forward head posture. The results of the multiple linear regression showed that the FHP with the standard coefficient (β= 0.64) was the most influential factor in predicting the incidence of neck pain.

Conclusion: The FHP has a greater impact than any other individual and job factors in creating neck pain. It may be concluded that awkward neck posture is the most important risk factor for neck pain in static sitting jobs such as dentistry.


Comparative Analysis of the Effect of Six Weeks Online Corrective Exercises and Posture Retraining on Pain, Disability, Percieved Fatigue, and Mental Workload Among Dentists in Shahrekord
Yousef Ghanbari, Farzaneh Gandomi,
Volume 11, Issue 3 (12-2023)
Abstract
Objectives: Musculoskeletal disorders and associated pains are represent significant and prevalent factors contributing to occupational injuries. The aim of this study was to investigate the effect of online upper cross syndrome-based exercises and the posture retraining on pain, disability, fatigue, and mental workload of experienced by dentists in Shahrekord city.
Methods: A total of 33 dentists were selected as the statistical sample and randomly assigned to three groups including, control (n = 11), Online National Academy of Sports Medicine (NASM) based corrective exercises (n=11), and posture retraining (n=11) groups. Baseline assessments were conducted, and outcomes were examined immidietly after the interventions. The experimental groups underwent the study interventions for six weeks, while the control group maintained their regular daily activities during this period. Primary outcome measure was pain, and secondary measures included disability, perceptual fatigue, mental workload, and quality of life. Within-group comparisons were analyzed using paired sample t-tests, and between-group comparisons utilized one-way analysis of variance.
Results: The results indicated that both exercise interventions positively affected pain, disability, perceptual fatigue, mental workload, and quality of life among dentists (P<0.05). Notably, correction of the upper crossed syndrome demonstrated a more significant effect compared to the posture retraining intervention (P<0.05).
Conclusion: The utilization of online NASM-based corrective exercises and posture retraining could have positive effects in reducing pain and disability and also improving the overall performance of dentists.

Seyeydeh Hasti Sadati, Mehdi Asghari, Maedeh Moradi Farahani,
Volume 12, Issue 1 (4-2024)
Abstract
Objectives: Awkward posture is a primary cause of musculoskeletal disorders (MSDs) in the dental profession due to the nature of dental activities. This study aimed to examine both observational and device-assisted posture assessment methods used to study dental professionals as well as the reported prevalence of MSDs among them.
Methods: A search was conducted in Scopus, PubMed, and Google Scholar databases for studies performed from 2000 to 2021 using specified keywords. In total, 31 out of the 541 articles found in the initial search were finally included in this study after the exclusion of ineligible articles, duplicates, conference presentations, systematic reviews, and letters to the editor.
Results: Based on the findings, the neck (58%), back and waist (54.9%), and shoulder and hand (29%) areas had the highest reported pain and disorder. Several posture evaluation methods, namely Rapid Upper Limb Assessment (19.4%), Rapid Entire Body Assessment  (19.4%), Electromyography (EMG, 13.8%), and Quick Exposure Check (QEC, 8.3%), were the most frequently used methods among all 17 methods employed in the studies.
Conclusion: Among the observational methods, the QEC method was the most practical one as it considered the experiences of dentists and various dimensions of dental tasks. Moreover, the EMG method was the most suitable device-assisted method for the assessment of posture in dentists. The use of questionnaires in conjunction with evaluation methods appears to enhance the understanding and effectiveness of posture assessment.

Volume 14, Issue 2 (6-2026)
Abstract
Background: Dentistry, as a profession characterized by a static nature, repetitive movements, and occupational stress, is considered a high-risk occupation for the development of musculoskeletal disorders and reduced quality of life. The aim of this research was to investigate the relationship between musculoskeletal disorders and quality of life among dentists.
Methods: This descriptive-analytical cross-sectional study was conducted in 2025 on 150 practicing dentists in the city of Ardabil. Samples were selected using the convenience sampling method. Data were collected using standard questionnaires, including the Nordic Musculoskeletal Questionnaire (NMQ) for musculoskeletal disorders and the World Health Organization Quality of Life (WHOQOL) questionnaire. Data analysis was performed using SPSS 26 software with Chi-square and logistic regression tests.
Results: The most commonly affected areas were the lower back (64.7%), neck (60.7%), and shoulders (52.1%). These problems had led to reduced professional activity in 28.7% of the individuals. Quality of life was at a moderate to low level, with the lowest score belonging to the environmental health domain (56.79 out of 100). A significant association was observed between lower quality of life and increased musculoskeletal complaints in some body areas (p < 0.05).
Conclusion: The results of this study indicate a very high and concerning prevalence of musculoskeletal problems and a moderate quality of life among dentists in Ardabil. Furthermore, the findings emphasize the necessity of implementing comprehensive intervention programs to improve workplace ergonomics and enhance the health and quality of life of dentists.
