RELATIONSHIP BETWEEN THE DEGENERATIVE CHANGES IN THE MANDIBULAR CONDYLE AND ARTICULAR EMINENCE INCLINATION, HEIGHT, AND SHAPE: A CBCT STUDY

Abstract

Objectives: This study aimed to analyze the articular eminence inclination and height and correlate these findings with the eminence shapes and degenerative condylar changes using cone-beam computed tomography (CBCT). Materials and Methods: The assessments were established on CBCT images of 566 temporomandibular joints (TMJ) that were included from the computer database. Age and gender were recorded for all individuals. Degenerative changes were examined in the articular surface of the condyle. The articular eminence (AE) inclination and height measurements were performed on central parasagittal slices of the TMJ. The shape of the AE was classified as box, sigmoid, flattened, and deformed. Results: The prevalence of degenerative changes in the condyle was higher in males, but no significant difference was found (p ˃ 0.05). The AE inclination and height have a relation with gender and age groups. The AE inclination and height results were greater in males (p < 0.05). The reduced mean values of eminence inclination and height in the +50-year-old group were detected (p < 0.05). Sigmoid and box-shaped articular eminence morphologies were more common. The eminence with deformed-shaped was related to two or more degenerative alterations in the condylar head. Conclusion: The degenerative condylar changes can affect eminence inclination and height by mechanical loading and changed articular dynamics. Gender and age have a significant effect on the AE morphology. The articular eminence shape is influenced by combinations of two or more degenerative changes.

Amaç: Bu çalışma, konik ışınlı bilgisayarlı tomografi (KIBT) kullanılarak artiküler eminens (AE) eğim ve yüksekliğini analiz etmeyi ve bu bulguları eminens şekilleri ve dejeneratif kondiler değişiklikler ile ilişkilendirmeyi amaçlamaktadır. Gereç ve Yöntemler: Toplam 566 temporomandibular eklemin (TME) KIBT görüntüleri değerlendirildi. Tüm bireylerin yaş ve cinsiyet verileri kaydedildi. Kondilin eklem yüzeyindeki dejeneratif değişiklikler incelendi. Artiküler eminens eğim ve yükseklik ölçümleri TME'nin santral parasagital kesitleri üzerinde yapıldı. AE'nin şekli kutu, sigmoid, düz ve deforme olarak sınıflandırıldı. Bulgular: Kondildeki dejeneratif değişikliklerin prevalansı erkeklerde daha yüksekti, ancak anlamlı bir fark bulunamadı (p ˃ 0.05). AE eğim ve yüksekliğinin cinsiyet ve yaş gruplarıyla ilişkisi vardır. AE eğim ve yükseklik değerleri erkeklerde daha fazlaydı (p < 0.05). +50 yaş grubunda eminens eğim ve yüksekliğinin ortalama değerlerinin azalmış olduğu tespit edildi (p < 0.05). Sigmoid ve kutu şekilli artiküler eminens morfolojileri daha yaygındı. Deforme eminens şekli, kondilin artiküler yüzeyindeki iki veya daha fazla sayıda dejeneratif değişiklik bulunması ile ilişkiliydi. Sonuç: Kondildeki dejeneratif değişiklikler; mekanik yükleme ve değişen eklem dinamikleri nedeniyle eminens eğim ve yüksekliğini etkileyebilir. Cinsiyet ve yaşın AE morfolojisi üzerinde önemli bir etkisi vardır. Artiküler eminens şekli, iki veya daha fazla dejeneratif değişikliğin kombinasyonlarından etkilenmektedir.
