Abstract
Background and Aims: Regarding the diversity of reported low- back pain among dentists in different countries and lack of control group in most of the previous studies, the purpose of this study was to compare low- back pain and related risk factors between male general dentists and pharmacists to determine the relation between dentistry and development of low back pain.
Materials and Methods: In this cross-sectional study, 261 male dentists were compared with 193 male pharmacists as a control group with Standardized Nordic Questionnaire (low back section). Subjects were at least one year in clinical practice after becoming qualified and did not suffer from connective tissue diseases and history of a traumatic event causing fracture in spinal column. The data were analyzed by Chi- square, T-test and logistic regression analyses.
Results: The prevalence of low back pain in the past 12 months was 54.8% in male dentists and 36.3% in male pharmacists (P=.001). Logistic regression analyses, adjustmenting for occupation, age, body mass index (BMI), smoking, working years and working hours per week, revealed that there was a significant association between being a dentist and having low- back pain (OR=2.54, P=0.001).
Conclusion: Dentistry as a profession in male gender is associated with low back pain, independent of age, body mass index (BMI), smoking, working years and working hours per week.

Abstract
Background and Aims: Constant dynamic and static activities are considered as the main cause of musculoskeletal problems among dentists. The aim of this study was to evaluate the musculoskeletal problems and related factors among dentists in specialized clinics and dental schools in Tehran in 2014 using the REBA method.
Materials and Methods: In this cross-sectional study, the dentists from clinics of dental schools in Tehran were selected as individual targets. Nordic anddemopghrphic questionnaire were completed through interview from dentists. In order to assess the musculoskeletal disorders, REBA method (Rapid Entire Body Assessment) was used. In this method, positions and postures of the dentists during their work was observed and recorded. Data was analyzed using Regression Logestic test.
Results: The obtained results showed that among 100 dentist, 6% were in the very high risk (15-11) for musculoskeletal problems and 17% and 25% were in high-risk (10-8) and average risk (7-4), respectively. Based on the findings from Nordic questionnaire, the most skeletal- muscle travail were related to the neck (60%), lumbar (58%) and rear (46%) consequently. It seemed that factors such as gender, body mass index (BMI), height, specialty, body posture during the work (standing or sitting), smoking and using the direct or indirect vision, had an impact on the musculoskeletal disorders.
Conclusion: Findings from the final scoring of REBA showed that a high percentage of dentists were struggling with skeletal- muscle problems and they were in moderate to high range of risk for these type of disorders.

Abstract
Background and Aims: The dentistry profession is one of the most injuring professions that causes most pains and hurts for dentists because of their lack of knowledge about the ergonomic position through the work. The purpose of this study was to assess the ergonomic position of dentists with RULA method in dentists of Bojnord.
Materials and Methods: In this cross-sectional study, all of the Bojnord’s county dentists were selected. RULA method and Nowerdik questionnaire were used for investigating the agronomical position, and muscular-skeleton position, respectively. The analysis was done by SPSS22 using regression and chi-square test. A P-value of less than 0.005 was assumed as significant.
Results: The most muscle-skeleton reports were 55.6% (35 persons) related to back, 54% (34 persons) related to shoulders, 50.8% (32 persons) related to waist, and 47.6% (30 persons) related to neck aches. In the last 12 months, 90.5% of dentists reported pains from at least one of organs of their bodies and 27% were supposed to leave their works which the sex (P=0.84), length (P=0.75), and weight (P=0.38) were not significantly related to this case.
Conclusion: According to the results of this study educational interventions is essential to prevent the musculoskeletal disorders in dentistry.

Abstract
Background and Aims: Dentists are at risk of musculoskeletal disorders due to their job characteristics. The purpose of this study was to compare the posture and musculoskeletal disorders of dentists with high and low work experience.
Materials and Methods: This analytical cross-sectional study research was conducted on 76 dentists in Urmia city. Based on work experience, the samples were divided into two groups: less experienced (less than 15 years) and experienced (15 years and more). The variables of forward head, kyphosis, round shoulder, and musculoskeletal disorders were compared in two groups. Forward head and round shoulder variables were evaluated by photography, kyphosis variable by flexible ruler, and musculoskeletal disorders were evaluated by Nordic questionnaire. Data analysis was done using descriptive statistics and analytical statistics (Kolmogorov-Smirnov test, Leven test, independent t-test and Yeoman-Whitney test).
Results: The independent t-test results showed that the angle of forward head, round shoulder, and kyphosis was higher in the high work-experience group than that of the low work-experience group (P=0.001). In comparing the prevalence of neck disorders, the results were significant such that the experienced group had more neck disorders (P=0.002). However, in examining the difference in the amount of disorders in other parts of the body, the difference between the two groups was not statistically significant (P>0.05).
Conclusion: Experienced dentists had a higher degree of forward head, round shoulder and kyphosis positions. Although, there are musculoskeletal disorders in both groups of dentists with low and high level of experience, neck disorders were more common in high-experienced dentists than that of low-experienced ones.

Abstract
Background and Aims: Musculoskeletal disorders (MSDs) are among the most common occupational health problems faced by dentists. Given their impact on dentists’ health and performance, the present study aimed to investigate the prevalence of MSDs among general and specialist dentists practicing in Babol, Iran.
Materials and Methods: In this cross-sectional study, the standardized Nordic questionnaire, consisting of general and specific sections, was distributed in person among dentists practicing in Babol, based on data obtained from the local Medical Council. Distribution was carried out after a telephone invitation and confirmation of willingness to participate. The questionnaire included items regarding pain and discomfort in different body regions such as the neck, shoulders, and lower back. The frequency of participants with MSDs was assessed based on gender, right/left handedness, specialty, playing sports, and participating in a specific sport. The mean age, weight, height, body mass index, weekly working hours, and work experience of dentists with and without MSDs were also compared. Data were analyzed using SPSS software version 22, employing independent t-tests, Chi-square tests, and Fisher’s exact test, with a significance level set at 0.05.
Results: Of the 182 dentists approached, 17 declined participation and 5 met the exclusion criteria. A total of 160 dentists (mean work experience: 15.65 ±9.26 years) were included in the study; of these, 100 (62.5%) were male, 95 (59.4%) were general practitioners, and 65 (40.6%) were specialists. The overall prevalence of MSDs in this population was reported to be 90%. The most commonly affected region was the neck (76.4%), while the least affected was the ankle (3%). A statistically significant association was found between engaging in a specific type of regular physical activity and a reduced incidence of MSDs (P<0.001). No significant associations were observed with other variables such as gender, handedness, specialty, or field of specialization (P>0.05). Furthermore, no significant differences were found in the mean height, weight, body mass index, weekly working hours, or years of experience between dentists with and without MSDs (P>0.05).
Conclusion: Musculoskeletal disorders are highly prevalent among dentists in Babol. Given this high prevalence, the development and implementation of educational programs on ergonomics, along with recommendations for targeted physical activity appear to be essential.
