Aim: To determine the prevalence of temporomandibular disorders (TMD) and neuromuscular system variations in navy scuba divers and to identify the risk factors for the development of TMD signs and symptoms before and after diving using a questionnaire, electromyography, stabilography, and Cone Beam Computed Tomography (CBCT). Materials and Methods: Twenty males aged 30 to 42 years. Each diver answered a questionnaire and undergone neuromuscular tests and muscular and postural examinations before (T0) and after (T3) diving, and CBCT. Results: The prevalence of TMD symptoms at T3 was approximately 93 versus a 32 per cent T0. The neuromuscular answers at T3 were highly different from the situation at T0 [percentage overlapping coefficient T0-T3 ρ =0,0001 (p<0,001]; impact T0-T3 p=0.0087 (p<0,01); also postural aspect were different at T3 (p<0.01). Clenching seemed to be the greatest risk factor for pain in the masticatory muscle system while holding the mouthpiece, and after diving. Limited mouth opening and clenching were responsible for the symptoms in the temporomandibular joints at T3. Exposure to cold water for long periods of time causes the mandible to protrude and, together the tendency to bite harder on one side, can result in dysfunction. Conclusions: Scuba divers exhibiting TMD-related symptoms have the greatest risk of developing temporomandibular joint dysfunction and neuromuscular changes during and after diving. After diving, TMD is also a common problem in divers who were asymptomatic before the dive.
