Objectives: The purpose of the study is to verify the correlation between teenagers` use of internet and temporomandibular joint disorders(TMJD) because TMJD patients gradually increase in high school students.
Methods: Subjects were 221 male high school students attending liberal arts and commercial schools from 9 to 21 of April, 2012. Students completed self-reported questionnaire.
Results: TMJD symptoms included crackling joint (32.1%), headache (18.6%), malocclusion (8.1%), and jaw fatigue and muscular aching (7.2%). Students having at least one symptom accounted for 49.8%. Students having at least one poor habit accounted for 83.7% and 34.0% of the students used internet for 3 hours.. Score of students experiencing shoulders and chest pain was 5.13±1.10 (p<0.05). Score of TMD afflicting area revealed 4.67±2.73 (p<0.05) in mastication pain (4.13±2.73 (p<0.05)) due to long hours of internet use. Score of jaw fatigue related to muscular pain was 4.31±1.96 (p<0.01). Duration of computer use was related to perceived TMJD symptoms (r=.153). Long duration of computer use was related to poor oral cavity habits (r=.157).
Conclusions: Male high school students can perceive slight TMD which needs self management and regular check-ups and try to prevent TMD by utilizing measurement tools on TMD. Also, this study helps to prevent from worsening TMD by shortening hours of computer utilization.
