Abstract
A group of 248 randomly selected high school girls, aged 15-16 years, compl eted a questionnaire and were examined clinically with regard to various or al habits and signs and symptoms of temporomandibular disorders (TMD). Comm on habits reported in the Literature, such as gum chewing, nail biting, bit ing foreign objects, clenching and bruxism, eating seeds and crushing ice, as well as two less reported habits, 'jaw play' and continuous arm leaning, were evaluated. The most outstanding finding was the high prevalence and i ntensity of gum chewing among our study group: 92% of the girls chewed dail y and 48% chewed gum for more than 3 h a day (intensive gum chewing). Stati stically significant associations were found between intensive gum chewing and muscle sensitivity (P < 0.001) and joint noises (P < 0.05), and between crushing ice and muscle sensitivity to palpation (P < 0.005). A positive a ssociation was found between 'jaw play' and joint disturbances: reported jo int noises (P < 0.01), catching of the joint (P < 0.01) and joint tension ( P < 0.001). A positive association was also found between arm leaning and r eported joint noises (P < 0.05), catching (P < 0.05), and joint tension (P < 0.005). There was no association between the presence of bruxism and musc le sensitivity to palpation or joint disturbances. The potential harmful ef fects of intensive gum chewing, 'jaw play', continuous arm leaning and ice crushing are presented in this study. In light of these findings, the profe ssional community should address these habits with proper data gathering, e xamination and consultation.
