Abstract

There have been many different theories on the etiology of temporomandibular disorders(TMDDs). ´f Y objective of this study was to investigate the effects of occlusal factors and recent life event changes as prediposing factor on the development of temporomandibular disorders.
To evaluate the above predisposing factor, the author used T-scan system(Tekscan Co. U.S.A.) for quantitative occlusal analysis, clinical examination for occlusal state and Social Readjustment Rating Scale(SRRS) for recent life event change units(LCU). 63 patients with TMDs and 57 patients with malocclusion presented at Wonkwang University Dental Hospital participated in this study.
The subjects were grouped by Angle´s classification and presence or absence. of TNIDs and parafunctiooA oral habits. Data gained with regard to contact number, contact fake, contact time, occlusal state(number"1rtotal teeth and occluding teeth, overjet, overbite) and occlusal interferences(protrusive posterior ,nonworiang side interference, and RCP-ICP slide) and recent life event changes. The data were processed . z analysed by SAS statistical package program. The results of this study were as follows
1. There were no significant differences on both quantitative occlusal contact analysis and occiusal state between TMDs group and Angle´s malocclusion group. Also, there were no differences among the Angle´tr classifications. But amount of overjet in TMDs group were more greater than that of malocclusion group
2. There was no difference on protrusive posterior contact, and balancing contact between TMDs group and Angle´s malocclusion group. Premature contact was more frequent in malocclusion group, but RCP-ICP slide was more frequent in TMDs group. And RCP-ICP slide was more frequent in Angle´s class Il ma:ocdusic than Angle´s I or III malocclusion.
3. life changes units in TMDs group were higher than those in malocclusion group. And recent life chaagt.. units in group with parafunctional oral habit were higher than those in group without parafuncnonal cf habits. Clenching was the most common habit among parafunctional oral habits.
