PURPOSE: This study aimed to evaluate the prevalence of work-related musculoskeletal pain (WMSP), analgesic use practices, pharmacological knowledge, attitudes toward unsupervised analgesic use, and ergonomic/non-pharmacological behaviors in this cohort.
PATIENTS AND METHODS: An online questionnaire was sent to third- to fifth-year Iraqi dental students using WhatsApp, Facebook, and Telegram platforms. The link was shared three times weekly during March-May 2026. The survey collected sociodemographic data, musculoskeletal pain experience, analgesic use patterns (especially non-steroidal anti-inflammatory drugs (NSAIDs) and paracetamol), pharmacological knowledge, attitudes toward unsupervised analgesic use, and ergonomic/non-pharmacological behaviors. Skip logic was applied to direct pain-related and analgesic-use items to eligible participants only.
RESULTS: Out of 1081 collected responses, 791 dental students reported WMSP (73.2%; 95% CI: 70.5-75.8). A significantly higher prevalence of WMSP was recorded among female students than among male students (75.3% vs 68.7%; p = 0.020), and WMSP prevalence differed significantly across academic years, ranging from 66.3% among 3rd-year to 77.5% among 5th-year respondents (p = 0.001). The most commonly reported affected areas were neck, lower back, and shoulders, with prevalences of 58.4%, 53.9%, and 42.2%, respectively. About half of students with WMSP used analgesics, mainly paracetamol (46.9%) and ibuprofen (33.6%). Analgesic users demonstrated lower knowledge and safer-attitude scores than non-users (both p ≤ 0.002). The multivariable analysis revealed that higher analgesic-related pharmacological knowledge was independently associated with lower odds of analgesic use (OR = 0.828, 95% CI: 0.793-0.864; p < 0.001).
CONCLUSION: A high prevalence of WMSP was reported among Iraqi dental undergraduates, with nearly half of affected students reporting analgesic use. Higher analgesic-related pharmacological knowledge was independently associated with lower odds of reported analgesic consumption. A combined approach utilizing ergonomic and pharmacological education may promote better pain-management behaviors and safer analgesic use; however, longitudinal or interventional studies are needed to evaluate its effectiveness.
