Objectives:
Search of factors influencing the occurrence of musculoskelettal problems (MSP) among Lebanese dental surgeons.
Patients And Methods:
Retrospective study, performed in September 2001. A 29 item-questionnaire exploring demographic and personal data, professional activity, the occurrence of musculoskelettal problems during the last month (MSPLM), and the twelve last months (MSPTLM) among Lebanese dental surgeons.
Results:
300 questionnaires--170 answers. Descriptive analysis--Age: 37 +/- 9 years; 141 men (83%); 96 general practitioners (56.5%); 93 (56%) practice sports ; stress: 94%; length of service: 12 +/- 8 years; duration: 7 +/- 1.75 hours per day and 5 +/- 0.75 days per week; breaks: 85 +/- 55 minutes per day; MSPLM: 66% ; pains: lumbar spine 85.5%, cervical spine 59%, shoulders and arms 62%, hands 10%, lower limbs 25%. Pins and needles: 32%; MSPTLM: 52.4%. Univariate analysis--Strong correlation for MSPLM occurrence with sports (p = 0.007), breaks duration (p = 0.005), occurrence of MSPTLM and current practice (general practitioners) p = 0.016. Multivariate analysis--Weight gain (p = 0.0119) x 6, history of MSPTLM (p = 0.000) x 21 and pins and needles (p = 0.0339) x 4,5 are the potential risk factors of MSPLM occurrence.
Conclusion:
The prevalence of MSP is high in our series. The preventive and curative care is insufficient, thus information and prevention are necessary.

Disorders of the Skeletal Muscle
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
