ABSTRACT
 Objective: The mandibular coronoid process is an anatomical structure related to mandibular function and movement. The elongated process may impinge on the zygomatic bones and restrict mouth opening. A significant portion of individuals with prolonged coronoid processes do not complain of pain, which may lead to misdiagnosis or delayed treatment. The objective of this study was to evaluate the concordance between coronoid process measurements obtained from panoramic radiography and cone beam computed tomography (CBCT) images. Material and Methods: A retrospective study design was employed, utilizing panoramic radiographs and CBCT images from the Department of Oral and Maxillofacial Radiology archives, excluding patients with prior maxillofacial surgery or certain pathologies. Levandoski analysis was used on panoramic radiographs and coronoidcondylar index (CCI) was used CBCT images to determine the coronoid process length. Results: A statistically significant difference was observed between the analysis methods (p<0.05). The length of the coronoid process was observed to be less in the Levandoski analysis than in the CCI. Although there was no significant difference in the length of the coronoid process between the genders when measured using CBCT, this measurement was found to be longer in males than in females when assessed using panoramic radiography (p<0.05). Conclusion: This study underscores the significance of CIBT as a dependable imaging modality for the accurate measurement of mandibular coronoid process length in comparison to panoramic radiography. The findings of this study mandate further research with larger populations to address its limitations and enhance diagnostic accuracy.

ÖZET
 Amaç: Mandibular koronoid proses, mandibular fonksiyon ve hareketle ilişkili anatomik bir yapıdır. Uzamış proses zigomatik kemiklere baskı yapabilir ve ağız açıklığını kısıtlayabilir. Uzamış koronoid prosese sahip bireylerin önemli bir kısmının ağrıdan şikâyet etmemesi yanlış tanıya veya gecikmiş tedaviye yol açabilir. Bu çalışmanın amacı panoramik radyografi ve konik ışınlı bilgisayarlı tomografi (KIBT) görüntülerinden elde edilen koronoid proses ölçümleri arasındaki uyumu değerlendirmektir. Gereç ve Yöntemler: Ağız, Diş ve Çene Radyolojisi Anabilim Dalı arşivindeki panoramik radyografiler ve KIBT görüntüleri kullanılarak, geçirilmiş maksillofasiyal cerrahi veya patoloji hikayesi olan hastalar hariç tutularak, retrospektif bir çalışma tasarımı kullanılmıştır. Koronoid proses uzunluğunu belirlemek için panoramik radyografilerde Levandoski analizi, KIBT görüntülerinde ise koronoid-kondiler indeks (KKİ) kullanılmıştır. Bulgular: Analiz yöntemleri arasında istatistiksel olarak anlamlı bir fark gözlendi (p<0.05). Koronoid proses uzunluğunun Levandoski analizinde KKİ'ye göre daha az olduğu görülmüştür. Koronoid çıkıntı uzunluğu KIBT ile ölçüldüğünde cinsiyetler arasında anlamlı bir fark olmamasına rağmen, panoramik radyografi ile değerlendirildiğinde bu ölçüm erkeklerde kadınlara göre daha uzun bulundu (p<0,05). Sonuç: Bu çalışma, panoramik radyografiye kıyasla mandibular koronoid proses uzunluğunun doğru bir şekilde ölçülmesinde güvenilir bir görüntüleme yöntemi olarak KIBT'nin önemini vurgulamaktadır. Bulgular, çalışma kısıtlamalarını ele almak ve tanısal doğruluğu artırmak için daha büyük popülasyonlarla daha fazla araştırma yapılmasını gerektirmektedir.
