Sažetak
The objective of the investigation was to determine the relationship between the position of the condyle head and disc position in the glenoid fossa between two different sections of same temporomandibular joints (TMJs) with partial anterior disc displacement (DD). M&M. The investigation was conducted on 40 patients with DD of TMJs (aged between 15 and 71 (mean: 35.5 years ; 1:3 ratio men to women). The clinical diagnosis of DD was confirmed by magnetic resonance imaging of bilaterally recorded TMJs. 9 TMJs with partial reducing DD were diagnosed. Partial DD with reduction was analyzed in the representative laterocentral or centromedial parasagittal section of TMJ. 34 joints with no disc displacement (NDD) of the same patients with DD in contralateral TMJ served as a control group of TMJs. Other categories were complete (n=15) reducing DD and complete (n=19) nonreducing DD. Position of the condyle and disc was calculated using the Kurita et al. method on the parasagittale view of the TMJ. Kruskal-Wallis test and Wilcoxon&#8217; test of pairs were used and in data analysis the left and the right TMJs of a single patient were presented as two entities. One NDD joint with osteoarthritis in a patient was excluded. Results showed that a statistically significant difference between the position of the disc in sections with DD and sections without DD in same TMJs with partial DD was determined (p<0.01), but no difference in condyle positions (dorsocranial displacement) depending on the existence of DD was found (p>0.05). The measured values between sections without DD of the groups of joints with partial DD with joints with NDD of all patients with DD showed no significant difference in either the disc position (p>0.05) or in condyle (p>0.05) position. Conclusion. There were differences of disc position in different parts of same TMJs with partial DD. The results of this study have shown that the dorsocranial condyle head position could not indicate the anterior DD in sections of same partial disc displaced TMJs, and in comparing with TMJs with NDD.
