Abstract

Aim: The aim of this study was to determine whether correlationsexisted between the fractal dimension (FD) valueof the mandibular condyle and radiographic findingsof degenerative joint disease (DJD) using cone beam CT(CBCT).Materials and Method: 100 TMJ CBCT images wereretrospectively analyzed. CBCT images of patients wereassessed with regard to erosive degenerative bone change(DBC) in the mandibular condyle. We divided eachcondyle into 3 groups and scored (0, 1, 2) according todiagnosis of DJD: with 0 indicating normal condyles ornon-demonstrable change, 1 indicating mild erosive DBCand 2 indicating severe erosive DBC. Fractal analysis (FA)was applicated to CBCT image of mandibular condyle.FD values were compared with the radiographic diagnosisscores.Results: ANOVA test showed that there was statisticallysignificant difference between the FD values of patientwith erosive DBC and patient having no erosive change.The average FD value of patient group 0 was 1.079, theaverage FD value of patient group 1 was 1.052, the averageFD value of patient group 2 was 1.036. Lower FD valuesand more severe degenerative changes were seen inpatient group 2.Conclusion: In our study, we found that as the gradeof bone degeneration increased, FD values decreased.These findings suggest a promising result in related topic.However, this paper is a preliminary study of FA andDBC. Further studies should be performed to ensure FA isclinically feasible.

Özet

Amaç: Bu çalışmanın amacı dental volumetrik tomografi (DVT) kullanılarak elde edilen dejeneratif eklem hastalığında mandibular kondile ait radyografik bulgular ile fractal boyut (FB) değerleri arasında korelasyon olup olmadığını araştırmaktır. Gereç ve Yöntem: 100 DVT eklem görüntüsü retrospektif olarak incelendi. Hastaların DVT görüntüleri mandibular kondilde eroziv dejeneratif kemik değişimi (DKD) açısından incelendi ve her bir kondil buna göre üç gruba ayrılarak skorlandı (0, 1, 2): 0 normal kondili, 1 kondilde hafif derece eroziv DKD, 2 kondilde ileri derece eroziv DKD göstermektedir. Fraktal analiz (FA), mandibular kondil DVT görüntüleri üzerine uygulandı ve radyografik diagnoz skorları ile karşılaştırıldı. Bulgular: Anova test değerleri, kondilde eroziv DKD olan hastaların FB değerleri ile olmayanlar arasında istatistiksel olarak anlamlı derecede farklılık olduğunu gösterdi. Hasta grubu 0’da ortalama FB değeri 1.079, grup 2’de 1.052 ve grup 3’de 1.036 idi. Daha yüksek dejeneratif değişimlerin görüldüğü hasta grubu 2’de daha düşük FB değerleri görüldü. Sonuç: Çalışmamızda, kemik dejenerasyon derecesi arttıkça FB değerlerinin de azaldığını gözlemledik. Bu bulgular konuyla ilgili umut verici bir sonuç ortaya koymakla beraber, bu araştırma FA ve DKD ile ilgili bir ön çalışmadır ve FA‘in klinik olarak uygulanabilir olması için daha ileri çalışmalar yapılmalıdır.
