Musculoskeletal disorders (MSDs) are the most common occupational illnesses in the world. Dental professionals are more prone to injuries and pain in their muscles, tendons, nerves, and joints, which are known as MSDs. Prolonged static postures, repeated actions, workplace designs, poor alignment, genetic predisposition, mental stress, physical conditioning, age, and nonwork activities are all factors that might contribute to musculoskeletal pain (MSP). This systematic review and meta-analysis was based on Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines, and the articles were retrieved from the search engines such as PubMed, Google Scholar, and Web of Science after fulfilling the eligibility criteria. After screening, a final of ten articles were included in the final analysis. This systematic and meta-analysis follows the PRISMA checklist. Medcalc software was used in order to find the significance of the prevalence of lower back pain, followed by neck pain, upper back pain, shoulder pain, and hand and wrist pain in dental practitioners. Significant differences were considered at P < 0.05. A total of ten studies were included, of which six studies met the criteria for the meta-analysis. The prevalence rates of musculoskeletal diseases were high. The lower back was the region most affected (47.753%, 95% confidence interval [CI]: 45.007–50.509), followed by the upper back body region (44.167%, 95% CI: 41.300–47.063%), neck pain (41.633%, 95% CI: 39.066%–44.234%), shoulder pain (33.608%, 95% CI: 31.222%–36.058% and 18.656%), and hand/wrist pain (95% CI: 16.359%–21.128%). Work-related MSP is the major health problem among dental professionals. Working posture of dental professionals is important and has been identified as a major risk factor for the development of work-related MSDs. A proper ergonomic design and posture can reduce the MSP. Therefore, further research is needed on possible ergonomics needed for preventing MSDs.

| Introduction|| |
Dentistry is a difficult profession that necessitates the capacity to maintain static postures for lengthy periods of time, among other things. Dentists have been found to have more frequent and severe health problems, notably musculoskeletal discomfort. Musculoskeletal disorders (MSDs) are the most frequent occupational ailments worldwide, impacting around one million people each year in nations such as the United Kingdom. Low back discomfort, joint ailments, and various types of repetitive strain injuries are among them. Around 83.8% of dentists in China suffer from neck pain. Various researchers in different study contexts have indicated considerably greater prevalence of musculoskeletal pain (MSP) throughout the Indian subcontinent. Dental practice does not result in contact injuries (like in sports), but it can cause muscular imbalance, neuromuscular inhibition, pain and dysfunction, owing to accumulated micro trauma, and the utilization of awkward positions on a regular basis. However, rather than a single risk factor, a mixture of many risk variables appears to function in the majority of cases. Prolonged static postures, repeated actions, workplace designs, poor alignment, genetic predisposition, mental stress, physical conditioning, age, and nonwork activities are all factors that might contribute to back pain. Maintaining a neutral and basic working posture that allows relaxed muscles and well-balanced is crucial since postures outside the neutral posture might cause musculoskeletal system (MSS) difficulties. This systemic review and meta analysis answers the question “What is the prevalence and risk factors of MSP in dental practitioners?”

| Results|| |
In this systematic review, 624 articles were retrieved from various databases (Pubmed, Scopus, Elsevier, and Journal of web). A total of 298 studies were excluded on the basis of abstracts and titles and then, 268 studies were excluded because they were unrelated to this purpose and duplicated, and 48 articles were excluded as parameters other than prevalence of MSP were assessed. After assessing for the eligibility, 10 articles were included for qualitative evaluation and 6 were analyzed quantitatively.
Characteristics of the reviewed studies are presented in [Table 1]. All papers studied the prevalence of MSDs including both males and females. The studies included employed nordic or self-designed questionnaire.
Across all musculoskeletal diseases, each article studies a part of MSD, including neck pain in five studies, lower back pain in five studies, upper back pain in three studies, shoulder pain in six studies, and wrist pain in four studies The study characteristics are summarized in [Table 1].
A total of six studies were included in the metaanalysis.
Prevalence of lower back pain among the study population
A total of five studies were evaluated which included a sample of 1295 dentists. The pooled prevalence was 47.7% (95% confidence interval [CI]: 45.007% to 50.509%) in the fixed-effect model and 60.8% (95% CI: 39.072% to 80.488%) in the random model, as per the random-effect model which was significantly higher. The heterogeneity was 97.91% for the lower back pain studies, suggesting a wider variability in this study which could be attributed to the wide age range of the dentists included for the analysis. Publication bias was negligible as per the Eggers and Begs test [Figure 2].
Prevalence of upper back pain among the study population
A total of three studies were evaluated which included a sample of 1170 dentists. The pooled prevalence was 44.167% (95% CI: 41.300%–47.063%) in the fixed-effect model and 41.994% (95% CI: 35.468% to 48.664%) in the random model, as per the random-effect model which was significantly higher. The heterogeneity was 74.55% for the upper back pain studies, suggesting a wider variability in this study which could be attributed to the wide age range of the dentists included for the analysis. Publication bias was negligible as per the Eggers and Begs test [Figure 3].
Prevalence of neck pain among the study population
A total of five studies were evaluated which included a sample of 1429 dentists. The pooled prevalence was 41.633% (95% CI: 39.066% to 44.234%) in the fixed-effect model and 48.602% (95% CI: 29.610% to 67.806%) in the random model, as per the random-effect model which was significantly higher. The heterogeneity was 97.83% for the neck pain studies, suggesting a wider variability in this study which could be attributed to the wide age range of the dentists included for the analysis. Publication bias was negligible as per the Eggers and Begs test [Figure 4].
Prevalence of shoulder pain among the study population
A total of six studies were evaluated which included a sample of 1499 dentists. The pooled prevalence was 33.608% (95% CI: 31.222% to 36.058%) in the fixed-effect model and 36.758% (95% CI: 24.000% to 50.538%) in the random model, as per the random-effect model which was significantly higher. The heterogeneity was 95.86% for the shoulder pain studies, suggesting a wider variability in this study which could be attributed to the wide age range of the dentists included for the analysis. Publication bias was negligible as per the Eggers and Begs test [Figure 5].
Prevalence of hand/wrist pain among the study population
A total of four studies were evaluated which included a sample of 1061 dentists. The pooled prevalence was 18.656% (95% CI: 16.359% to 21.128%) in the fixed-effect model and 26.848% (95% CI: 15.805% to 39.591%) in the random model, as per the random-effect model which was significantly higher. The heterogeneity was 92.45% for the hand/wrist pain studies, suggesting a wider variability in this study which could be attributed to the wide age range of the dentists included for the analysis. Publication bias was negligible as per the Eggers and Begs test [Figure 6].
Quality of risk assessment
All included studies were cross-sectional studies, so the Axis tool was used to evaluate the quality. The quality rating is from low risk to high risk, and low risk indicates high-quality articles [Figure 7].
| Discussion|| |
MSDs are delicate tissue wounds brought about by abrupt to repetitive movement, force, vibration, and abnormal positions. Musculoskeletal issues (MSDs) have increased. During the prior, it became more and more widespread in the world. MSDs are common occupational disorder among dental practitioners because of abnormal work posture. In most studies, the prevalence rate was high. Therefore, the dental practitioners are particularly at high risk of MSP. This was also evident when looking at the prevalence rates of the individual body regions.
Lietz et al. conducted a meta-analysis of MSDs among the dental professionals in Western countries where the prevalence of MSDs was high. The prevalence rates of musculoskeletal diseases and pain ranged from 10.8% to 97.9%, with pooled annual prevalence rate of 78.0% (95% CI: 60.2–95.8). Ohlendorf et al. also observed the prevalence rates of the individual body region, and the neck was the most frequently affected body region (pooled annual prevalence: 58.5%, 95% CI: 46.0–71.0). The author observed that the static working posture possibly contributed to particular muscular strains in the neck. Ohlendorf et al. also stated that other studies also found high prevalence rates for neck pain (above 66%) among Asian dental professionals.
Awareness of interventions or prevention strategies is needed to effectively manage and prevent injuries. Applying ergonomics to the practice of dentistry provides safety benefits and also ameliorate performance objectives through greater productivity., A good posture provides the dentist more working energy, lower stress level, increased comfort, lack of pain and muscular tension, and a lower risk for therapeutic errors. Aerobic exercise must be performed 3–4 times a week for at least 20 min. Aerobic exercise increases blood flow to all tissues and improves their ability to use oxygen. Prevention of chronic pain requires dentists to gain more knowledge, change their habits, select appropriate ergonomic equipment, and have a break period after each operation with stretching exercise. Additionally, exercise plays an important role in their career to be healthy, to be safe, and have longer practice years.
| Conclusion|| |
This study shows evidence that work-related MSP are the major health problems in dental professionals. Our findings revealed that there are high prevalence rates of MSDs. Different regions of the body were affected by MSP, especially lower back followed by neck, upper back, shoulder, and hand and wrist. Working posture of dental professionals has an important role, and it has been found to be a main risk factor for the development of work-related MSDs and maintaining poor posture for clinical procedure for longer duration can lead to MSP which increases gradually with time. A proper ergonomic design and posture can reduce the MSP. Therefore, further research is needed on possible ergonomics and exercises that can reduce the musculoskeletal disease among dental professionals.
