Abstract

Objective: To estimate if a correlation exists between edentulousness type and changes in the articular eminence inclination (AEI) and to compare these data with the trabecular structure of the mandibular condyle using fractal analysis.
Material and Methods: A total of 88 panoramic radiographs and 176 temporomandibular joints (TMJ) of four groups (n=22), which were divided according to dental status, were evaluated according to the AEI and fractal dimensions (FD) of the temporomandibular joints by one radiologist using the ImageJ (National Institutes of Health. MD, USA) program, retrospectively. The conformity of the values with normal distribution was evaluated using the Shapiro-Wilk test. A one- way ANOVA model was used while comparing the edentation status and relationships between FDs, and AEI measurements were assessed using Pearson’s correlation analysis. The level of statistical significance was taken as p<0.05. The SPSS (ver. 23) statistics package was used for calculations.
Results: No correlation was detected between AEI, FD, and edentate status. However, a negative relation between AEI and FD in unilateral edentate groups on the opposite sides was estimated.
Conclusion: The excess chewing force in the dentate side and the increase in AEI due to the movement area of the condyle narrows increased the amount of resorption in the TMJ.

Farklı Dişsizlik Türlerindeki Mandibuler Kondil Fraktal Boyutları ve Artiküler Eminens Eğimlerinin Karşılaştırmalı Değerlendirilmesi

Abstract

Amaç: Dişsizlik türü ile artiküler eminens eğim (AEE) farkları arasında bir korelasyon olup olmadığının tespiti ve bu verilerin fraktal analiz ile saptanan mandibuler kondilin trabeküler yapısı ile karşılaştırılmasıdır.
Gereç ve Yöntemler: Dişsel durumlarına göre sınıflandırılan 4 gruba (n=22) ait toplamda 88 adet panoramik radyograftaki 176 adet temporamandibular eklem (TME), AEE ve fraktal boyut (FB) açısından Image J (National Institutes of Health. MD, USA) programı kullanarak bir radyoloji uzmanı tarafından değerlendirildi. Değerlerin normal dağılıma uygunluğu Shapiro- Wilk testi kullanılarak değerlendirildi. Dişsizlik durumu ve FB/AEE ilişkisi karşılaştırılırken tek yönlü ANOVA modeli ve Pearson korelasyon analizi kullanıldı. İstatistiksel anlamlılık düzeyi p<0.05 olarak alındı. Hesaplamalarda SPSS (ver. 23) istatistik paketi kullanıldı.
Bulgular: AEE, FB ve dişsizlik durumu arasında korelasyon saptanmadı. Ancak tek taraflı dişsiz grupların karşı tarafında AEE ile FB arasında negatif bir ilişki olduğu saptandı.
Sonuç: Dişli taraftaki çiğneme kuvvetinin fazla olması ve kondilin hareket alanının daralmasına bağlı AEE artışı TME'deki rezorpsiyon miktarını artırmıştır.
