Abstract

Amaç: Bu araştırma, panoramik radyografileri kullanarak periapikal lezyonlu ve sağlıklı alt daimi 1. büyük azı dişlerinin trabeküler kemik fraktal boyut değerlerinin yaş ve cinsiyete göre incelenmesi amacıyla gerçekleştirildi.

Gereç ve Yöntem: Araştırmaya 6-16 yaş arasındaki toplam 216 hastanın panoramik radyografi görüntüleri dahil edildi. Her bir dijital panoramik radyografi üzerinde iki ayrı bölgeden (periapikal lezyonlu ve sağlıklı 1.büyük azı dişinin apeksindeki trabeküler kemik bölgesinden), 25x25 piksel boyutunda belirlenen ROI’lere, ImageJ programı kullanılarak fraktal analiz uygulandı ve fraktal boyut hesaplamaları yapıldı. Gerekli istatistiksel analizler yapıldı. Önem düzeyi p<0,05 olarak alındı.

Bulgular: Çalışma sonuçlarına göre lezyonlu bölgenin fraktal boyut değeri ortalaması 1,106 iken, sağlıklı bölgenin fraktal boyut değeri ortalaması 1,116’dır. Lezyonlu ve sağlıklı grubun fraktal boyut değerleri arasında istatistiksel olarak anlamlı bir farklılık bulunmadı (p>0,05). Fraktal boyut değerleri ile yaş ve cinsiyet arasında istatistiksel olarak anlamlı bir ilişki tespit edilmedi (p>0,05).

Sonuç: Fraktal analiz güvenilir bir yöntem olmasına rağmen, araştırmacılar arasında fikir birliği sağlanabilmesi için histolojik ve klinik parametrelerin yürütülen çalışmalara entegre edilmesi büyük bir öneme sahiptir.

EVALUATION OF FRACTAL ANALYSES OF THE TRABECULAR BONE REGION IN LESIONED AND HEALTHY MANDIBULAR FIRST PERMANENT MOLARS ACCORDING TO AGE AND GENDER ON PANORAMIC RADIOGRAPHS

Abstract

Purpose: This study was conducted to examine the fractal dimension values of the trabecular bone of mandibular first permanent molars with periapical lesions and healthy ones according to age and gender, using panoramic radiographs.

Material and Methods: Panoramic radiographs of a total of 216 patients aged between 6 and 16 years were included in the study. Fractal analysis was applied using the ImageJ program to the regions of interest (ROI’s) of 25x25 pixels determined from two different regions (the trabecular bone region at the apex of the first permanent molar with periapical lesions and the healthy one) on each digital panoramic radiograph, and fractal dimension calculations were performed. Necessary statistical analyses were conducted, and the significance level was set at p<0.05.

Results: According to the results of the study, the average fractal dimension value of the lesioned region was 1.106, while the average fractal dimension value of the healthy region was 1.116. No statistically significant difference was found between the fractal dimension values of the lesioned and healthy groups (p>0.05). No statistically significant relationship was found between fractal dimension values and age and gender (p>0.05).

Conclusion: Although fractal analysis is a reliable method, it is crucial to integrate histological and clinical parameters into the conducted studies to achieve consensus among researchers.
