Amaç: Kron-kök kırığı görülen protetik tedavi uygulanmamış kanal tedavili dişlerin; tedavide kullanılan restoratif materyal (amalgam, kompozit), restorasyonun konumu [(mezio-oklüzal (MO), disto-oklüzal (DO), mezio-oklüzo-distal (MOD)] restorasyonun ağızda kalma süresi, kırığın gözlendiği diş grubu, bireyin molar kapanış ilişkisi ve bruksizm alışkanlığı gibi parametrelere göre dağılımının incelenmesidir. Gereç ve Yöntemler: Ağız, Diş ve Çene Radyolojisi Ana Bilim Dalı Kliniğine diş kırığı şikâyeti ile başvuran, yaş aralığı 19-62 yıl olan, 56 kadın ve 44 erkek olmak üzere 100 hastaya ait bilgiler [bireyin yaşı, cinsiyeti, kırılan dişin numarası, uygulanan koronal restorasyonun konumu (MO, DO, MOD), kullanılan restorasyon materyali, restorasyonun ağızda kalma süresi, kanal tedavisinin kalitesine yönelik skorlama, Angle molar kapanış sınıflaması, bruksizm teşhisine yönelik anket soruları ve klinik bulgular)] hazırlanan formlara kaydedilmiştir. Bulgular: Çalışmaya dâhil edilen 100 bireyin kron-kök kırığı gözlenen dişlerinin tamamı molar ve premolar gruptan idi, kesici ve kaninlerde kronkök kırığı saptanmadı. Kron-kök kırığı gözlenen kanal tedavili dişlere uygulanan restorasyonların ağızda kalma süreleri ortalama 4,18±3,25 yıl idi. Restorasyon konumu ve kullanılan restoratif materyal ile restorasyonun ağızda kalma süresi arasında istatistiksel olarak anlamlı ilişki saptanmadı. Bununla birlikte, en az kırık MO kaviteye sahip restorasyonlarda gözlenmiş ve amalgam ile tedavi edilen dişlerde daha fazla kron-kök kırığı izlenmiştir. Bireyin bruksizm alışkanlığı, kapanış ilişkisi, cinsiyeti ile kırılan diş arasında istatistiksel olarak anlamlı ilişki bulunmamıştır. Sonuç: Bireyin estetik beklentileri de göz önüne alınarak kanal tedavili dişlerde uygun koronal restorasyon planlanması önerilmekle birlikte, direkt restoratif tedavilerin klinik performanslarının farklı risk faktörlerinden etkilenme durumlarının değerlendirilebilmesi için prospektif çalışmalara ihtiyaç duyulmaktadır.

Objective: The aim of this study was to evaluate the distribution of endodontically treated teeth with crown-root fracture without any prosthetic treatment according to such paratmeters: restorative material (composite, amalgam), location of the restoration [(mesio-occlusal (MO), disto-occlusal (DO), mesio-occluso-distal (MOD)], duration of the restoration, tooth group in which the fracture is observed, molar occlusion and bruxism habit of the individual. Material and Methods: Data [age, gender, fractured tooth number, position of applied coronal restoration (MO, DO, MOD), restoration material used, duration time for restoration, scoring for quality of root canal treatment, Angle molar occlusion classification, questionnaire and clinical findings for bruxism)] belongs to a houndred of patients (56 females and 44 males), aged between 19-62 years, who referred to Department of Oral and Maxillofacial Radiology Department with the dental fracture complaint were recorded in the prepared forms. Results: All of the teeth of the 100 individuals included in the study were in molar and premolar groups and no crown-root fracture was observed in incisors and canines. The mean duration time of coronal restorations was 4.18±3.25 years. There was no statistically significant relationship between the restoration position and the restorative material used and the duration of restoration in the mouth. It was observed that MO cavities had minimum and amalgam restorations showed maximum number of crown-root fractures. There was no statistically significant relationship between the bruxism habit of the individual, occlusion, gender and fractured tooth. Conclusion: Considering the aesthetic expectations of the individual,
appropriate coronal restoration planning for endodontically-treated teeth is recommended, but prospective studies are needed to assess the impact of different risk factors on the clinical performance of direct restorative treatments.
