Sažetak
The etiology of the occurrence of sounds and the role of occlusion, has not been yet entirely clarified. Objective of investigation: The objective of this investigation was to determine the effect of occlusal relationships on the occurrence of sounds in the TMJ. Methods: A group of 100 subjects, aged from 24-52 years (X=35.03&#61617 ; ; ; 6.92) was examined. The existence of sounds was registered by means of a clinical examination and auscultation by stethoscope and classified according to character in click or crepitation. The number of teeth, the number of teeth in occlusion, type of occlusion (canine guided occlusion, group function and balanced occlusion) was determined by clinical examination. Overbite and overjet were measured. RCP position was determined by chin-point technique, and fixing by Lucia-jig. The sliding from RCP to IKP position was determined in the anteroposterior, vertical and latero-lateral direction. A precise calliper was used to measure movement. Results: 29% of the subjects had a clinically determined sound, in 27% it was click, and in 2% it was crepitation. The Pearson &#967 ; ; ; &sup2 ; ; ; test analysis shows statisticly significant difference (p<0.05) only for the occurence of crepitation in relation to the number of teeth, number of teeth in occlusion and overjet. The same is confirmed by the analysis of variance (ANOVA). Conclusion: Overjet, difference in the position of RCP-ICP ; sliding from RCP into ICP, and type of occlusion, i.e. mediotrusion interferences, do not have an influence on the occurrence of sound in the TMJ. A reduction in the number of teeth and the number of teeth in occlusion, have an influence on the occurrence of crepitation. If the value of overjet increases the probability of the occurrence of crepitation is significantly increased.
