Background: Non-specific pain of low back and neck has direct impact on quality of life, active days at work, and health care costs. The purpose of this study was to determine the pain intensity and disability index for low back and neck among dentists. Materials and Methods: This cross-sectional study was conducted among 80 dentists (44.6% female and 55.4% male). Dentists pain intensity and low back and neck disability index were evaluated with the self-administered visual analog scale and Oswestry questionnaire, respectively. Statistical data analysis was done using SPSS. Results: Disability index of low back and neck has been reported equal to 26.6 ± 10.7 and 22.0 ± 8.8, respectively. Also the data showed the average pain intensity of low back and neck to be 75.5 ± 24 and 49.6 ± 19.7. The result showed significant relationship between pain intensity and disability index for low back and neck with body mass index (BMI) and exercise (P < 0.05). Conclusions: According to results, dentists have a high pain prevalence and moderate disability index of low back and neck. Also based on the relationship between the pain and disability index values with BMI and exercise, we recommend practice of relaxation and stretching exercises during breaks in the dentists work schedules to minimize the risk of work-related musculoskeletal disorders among dentists.

BACKGROUND: Non-specific low back pain (LBP) has a direct impact on the quality of life, active days at work and health care costs. AIM: This study was conducted to determine the relationship between LBP and thoracic kyphosis angle among dentists. MATERIAL AND METHODS: This cross-sectional and descriptive-analytical study carried out in the form of census among 84 dentists employed in a specialised clinic in Iran. Dentists LBP prevalence and intensity and thoracic kyphosis angle were evaluated respectively with the self-administered body map questionnaire, visual analogue scale and flexicurve ruler. Statistical data analysis was done using SPSS software, version 22. RESULTS: The data showed that the prevalence of LBP in dentists was 44.9% and intensity of LBP was reported about 71.9 ± 19.34. Pearson correlation coefficient between thoracic kyphosis angle and dentist’s characteristics was not significant except for work experience. The single linear regression model showed that 1.3% of thoracic kyphosis angle changes was positively dependent on LBP. Also, the present study proved that thoracic kyphosis angle changes were positively dependent to 2.6%, 10.8% and 5.7 percent of age, work experience and Body Mass Index (BMI), respectively. CONCLUSION: Despite the lack of significant statistical relation between LBP and thoracic kyphosis angle, there is a high prevalence and intensity of LBP among Dentists. To reduce the risk of work-related LBP among dentists, managing factors such as BMI, work postures and exercises during work should be taken into consideration.

Background-Occupational stress antagonizes human health directly as well as by instigating behavioral adversities like smoking; though it's relation with latter is yet unveiled. This study aimed at ascertaining the relation between occupational stresses and smoking status among workers of a steel industry in Iran. Material and Methods-This cross-sectional descriptive study was conducted among 105 workers of steel industry in Iran. Standardized Health and Safety Executive Management Standards Indicator Tool (HSE-MS IT) along with subjects' demographic features were used to assess occupational stress; while smoking status was measured by standardized methods of Otten et al (1999). Results-Response rate was 86.7% as 91 completed questionnaires were received back. Mean age of smoking and non-smoking workers 39.5±10.2 & 38.4±5.5 respectively (data presented as mean with standard deviation-M±SD), work experience of smokers and non-smokers 13±6.1 & 12.9±5.9 years respectively, while 90.4% were married. Total occupational stress scored 2.96±0.35; 13.5% staff were at high stress risk. Outcome scores were significantly different between smokers and non-smokers in stress dimensions including role, relationships, managers' support and peer support. Conclusion-Although smoking workers revealed better situation in role dimension, yet smoking employees depicted higher stress in relationships, managers' support and peer support dimensions. Inferences qualify for imperative measures to implicate smoking cessation programs, as well as regime to attenuate occupational stress at workplaces.
