Abstract
Musculoskeletal disorders (MSDs) constitute a significant occupational hazard among dental practitioners. An online-based e-survey was conducted among 252 registered dentists of Nepal using the Nordic musculoskeletal questionnaire (NMQ) to assess musculoskeletal complaints and work-related characteristics. Musculoskeletal complaints in lower regions were found to be highly prevalent among dental practitioners with prevalence of 76, 27 and 28.2% in the last 12 months, 1 month and 7 days, respectively, followed by musculoskeletal complaints in the neck, wrist/hand and shoulder. Musculoskeletal complaint during the last 12 months was significantly associated with age, years in dental practice after graduation and leave from duty in the past 12 months. Similarly, educational qualification, medical comorbidities and leave from duty were associated with complaints in the last 1 month. Musculoskeletal complaint during the last 7 days was associated with gender, working hours in a day, practice of four-handed dentistry and patients examined in a day.

Ergonomic Risk Assessment of Dental Students-RULA Applied to Objective Kinematic Data. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph181910550. [PMID: 34639850 PMCID: PMC8508251 DOI: 10.3390/ijerph181910550] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Revised: 10/04/2021] [Accepted: 10/06/2021] [Indexed: 01/27/2023]
Abstract
Musculoskeletal disorder (MSD) is already prevalent in dental students despite their young age and the short duration of dental practice. The current findings state that the causes of MSD are related to posture during dental work. This study aims to investigate the ergonomic risk of dental students. In order to analyze the ergonomic risk of dental students, 3D motion analyses were performed with inertial sensors during the performance of standardized dental activities. For this purpose, 15 dental students and 15 dental assistant trainees (all right-handed) were measured in a team. Data were analyzed using the Rapid Upper Limb Assessment (RULA), which was modified to evaluate objective data. Ergonomic risk was found for the following body parts in descending order: left wrist, right wrist, neck, trunk, left lower arm, right lower arm, right upper arm, left upper arm. All relevant body parts, taken together, exhibited a posture with the highest RULA score that could be achieved (median Final Overall = 7), with body parts in the very highest RULA score of 7 for almost 80% of the treatment time. Dental students work with poor posture over a long period of time, exposing them to high ergonomic risk. Therefore, it seems necessary that more attention should be paid to theoretical and practical ergonomics in dental school.

Abstract
Musculoskeletal disorders (MSDs) frequently occur among dental practitioners and present a significant occupational burden with an early onset in the dentists' career. This study aimed to analyze the five-year development of self-reported overall MSDs among the dentistry students during the course of their studies and to assess the possible influence of the risk as well as protective factors. The questionnaire inquiry was performed among the first-year dentistry students, regarding the occurrence of MSDs and the presence of potential risk and protective factors. The same students were followed, and they filled in the same questionnaire in the middle and at the end of their studies. A total of 73 dentistry students and 28 general medicine students participated. The occurrence of the overall MSDs statistically significantly increased from 30.1% at the beginning of the first year to 45.2% at the end of the fifth year among the dentistry students. The top-level sport was statistically significantly associated with the higher occurrence of MSDs in the fifth year and with the development of new MSDs between the first and the fifth year. This longitudinal prospective evaluation showed a significant increase in the MSDs occurrence among the dentistry students during their studies.

Abstract
BACKGROUND Work-related Musculoskeletal Disorders (WMSDs) are major challenges in the occupational health services industry. Dental practitioners are regularly subjected to ergonomic risks, which can cause Musculoskeletal Disorders (MSDs) in various body regions. OBJECTIVE This comparative cross-sectional study aimed to investigate MSDs and select a proper ergonomic risk assessment method in dental practice. METHODS This study was conducted on 70 dentists and 70 administrative staff of dental offices (comparison group) from Shahroud, Iran. The Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) and two observational ergonomic risk assessment methods, including Quick Exposure Check (QEC) and Rapid Entire Body Assessment (REBA), were utilized. RESULTS The results suggested that the mean score of musculoskeletal discomforts was significantly higher in dentists than in the administrative personnel. Additionally, the results of multiple regression analysis technique inferred that job tenure, working hours, and age had a significant impact on total MSDs. Regular exercise was found to significantly reduce neck discomfort complaints. It was also found that QEC was more effective in predicting musculoskeletal discomforts compared to REBA. CONCLUSION Considering the high incidence of WMSDs in dentists, various interventional measures revolving around ergonomically redesigned workstations, enhanced physical working conditions, and ergonomic training courses are suggested.

Abstract
The occupation of dental assistants (DAs) involves many health risks of the musculoskeletal system due to static and prolonged work, which can lead to musculoskeletal disorders (MSDs). The aim of the study was to investigate the prevalence of MSDs in DAs in Germany. Methods: For this purpose, an online questionnaire analyzed 406 (401 female participants and 5 male participants, 401w/5m) DAs. It was based on the Nordic Questionnaire (lifetime, 12-month, and seven-day MSDs’ prevalence separated into neck, shoulder, elbow, wrist, upper back, lower back, hip, knee, and ankle), and occupational and sociodemographic questions as well as questions about specific medical conditions. Results: 98.5% of the participants reported complaints of at least one body region in their lives, 97.5% reported at least one complaint in the last 12 months and 86.9% affirmed at least one complaint in the last seven days. For lifetime, 12-month and seven-day prevalence, the neck was the region that was most affected followed by the shoulder, the upper back and the lower back. Conclusion: The prevalence of MSDs among German (female) DAs was very high. The most affected area is the neck, followed by the shoulder, the lower back, and the upper back. It, therefore, seems necessary to devote more attention to ergonomics at the working practice of DAs as well in education and in dental work.

Abstract
The purpose of the study was to describe the occurrence of the most common complaints related to MSDs in Czech dentists and to assess the risk factors affecting them. A questionnaire survey of 581 Czech dentists (the response rate 72.6%) was conducted in 2011. The questionnaire ascertained general information about the respondents, their work habits and environment along with the occurrence of musculoskeletal disorders. The respondents filled out the questionnaires during the educational events organized by the Czech Dental Chamber. At least mild difficulties associated with the motoric system were reported by 96.9% of the respondents, with 66.3% of respondents reporting moderate or major difficulties. Back and neck pain followed by shoulder pain and headache were the most common complaints in our sample. According to our data: age, gender, length of practice, a history of serious MSDs, the occurrence of MSDs in blood relatives, the perception of work as psychologically demanding, and especially a perceived moderate/bad general health were significantly associated with the four most common musculoskeletal complaints. Some of the factors were found as protective. This study suggests that MSDs represent a significant burden for Czech dentists and further research is needed to elucidate this issue.

Abstract
The literature on upper limb musculoskeletal disorders (UL-MSD) in different groups of healthcare workers was reviewed: 65 relevant studies were collected. In dentists, the neck was the most frequently affected segment, with prevalences up to 73% and exceeding 50% in 7 out of 12 studies. In dental hygienists and in laboratory technicians, the hand/wrist had the highest prevalence in the majority of the studies. In nurses, the most seriously affected anatomic sites were the neck and shoulders. Physiotherapists had the lowest prevalence of UL-MSD. A high prevalence of upper limb disease, mainly carpal tunnel syndrome, was reported in dentists, dental hygienists, anesthesia nurses and endoscopists. The high prevalence of upper limb disorders/diseases reported in health personnel supports the hypothesis of a significant risk in these workers. However, the possible role of biomechanical overload, as much as that of stress or other personal factors, cannot be currently assessed. Practitioner Summary: Published studies support the hypothesis of a significant risk of upper limb musculoskeletal disorders in healthcare activities. The neck was the most frequently affected segment in dentists, the hand/wrist in dental hygienists and in laboratory technicians, and the neck and shoulders in nurses. Lower prevalence was reported in physiotherapists. A high prevalence of carpal tunnel syndrome was also observed in various healthcare activities.

Abstract
OBJECTIVES The aims of this study were to investigate the prevalence and nature of some health and lifestyle problems among dentists in United Arab Emirates (UAE). METHOD A cross-sectional study with a one-stage complex sampling technique using a self-reported questionnaire distributed to all 844 dentists, working in three cities (Abu Dhabi, Dubai and Sharjah) in UAE. RESULTS Seven hundred and thirty-three (87%) dentists, aged 22-70 years, responded. More than half (n = 442, 61%) of dentists do not exercise regularly. Around one-seventh of the dentists are smokers. One hundred and eighteen dentists (16%) reported having some known systemic problem. The most common systemic health problems were cardiovascular diseases (n = 56, 8%). CONCLUSION The present study indicates that the prevalence of exercise among dentists in UAE is relatively low and some systemic health problems, especially cardiovascular diseases, are present among dentists practicing in UAE. Cigarette consumption is relatively high in this population of dentist. Further continuing education and investigation of the appropriate intervention to improve rates of exercise and reduce the level of smoking among dentists in UAE is needed, and this may help reduce the level of systemic disease.
