Farklı İskeletsel Yapıdaki Bireylerde Maturasyon İndikatörlerinin Değerlendirilmesi

Amaç: Bu çalışmanın amacı, Sınıf I, Sınıf II ve Sınıf III bireylerde diş yaşı, kronolojik yaş, el-bilek maturasyonu ve servikal vertebra maturasyonu arasındaki ilişkileri değerlendirmektir.Yöntem: Bu çalışmada 8-18 yaş arası 289 kişinin (151 kız, 138 erkek) panoramik, el-bilek ve sefalometrik radyografileri değerlendirildi. Sagital iskelet maloklüzyonuna göre olgular Sınıf I, Sınıf II ve Sınıf III olacak şekilde üç ana gruba ayrıldı. Bireylerin diş yaşları Demirjian yöntemine göre belirlendi. Olguların el-bilek radyografileri Fishman maturasyon göstergeleri kullanılarak değerlendirildi. Servikal vertebra maturasyon evreleri, Bacetti ve ark. tarafından geliştirilen yöntemle değerlendirildi. Değişkenler arasındaki ilişkileri ölçmek için Spearman sıralama korelasyon katsayıları kadın ve erkek için ayrı ayrı kullanıldı.Bulgular: Tüm gruplarda hem kadın hem de erkek bireyler için değerlendirilen tüm değişkenler arasında Spearman korelasyon katsayısında farklı düzeylerde anlamlı bir pozitif korelasyon görüldü (p< 0.01). En düşük korelasyon, Sınıf II grupta kronolojik yaş ile iskelet diş yaşı arasında bulundu (r: 0.413). Servikal vertebra maturasyonu ile el-bilek maturasyonu arasındaki korelasyon, tüm gruplarda her iki cinsiyet için yüksekti (p< 0.01).Sonuç: Çalışmamızın sonuçlarına göre, pubertal büyüme atılımı ve gelişim evrelerini tanımlamak için; servikal vertebra maturasyonu el-bilek maturasyonu değerlendirmesine alternatif olarak kullanılabilir. Ancak, daha büyük örneklem büyüklüğüne sahip gelecek çalışmalar, diş yaşının güvenilirliği kanıtlamada yardımcı olabilir.

The Assessment of Maturation Indicators in Individuals with Different Skeletal Pattern

Objective: The aim of this study is to evaluate the relationships among dental age, chronological age, hand-wrist maturation and cervical vertebral maturation in Class I, Class II and Class III individuals.Method: Panoramic, cephalometric and hand-wrist radiographs of 289 individuals (151 girls, 138 boys) aged between 8 and 18 were evaluated in this study. Subjects divided into three main groups as Class I, Class II and Class III according to their sagittal skeletal malocclusion. The dental ages of the individuals were defined according to the Demirjian’s method. The Fishman maturation indicators were used for evaluating the hand-wrist radiographs and the method improved by Bacetti et al. were used for evaluating the maturation stages of the cervical vertebrae. The Spearman correlation analysis was used to evaluate the relationships between the variables separately for males and females.Results: The Spearman correlation coefficient indicated a significant positive correlation at different levels between all variables evaluated for both female and male individuals in all groups (P< 0.01). The lowest correlation was found between chronological age and dental age skeletal in Class II group (r: 0.413). The correlation between cervical vertebra maturation and hand-wrist maturation were highly positive for both sexes in all groups (P< 0.01).Conclusion: According to the results of our study, to define the growth spurt and developmental stages, cervical vertebrae maturation could be used as an alternative to hand-wrist maturation assessment. However, additional studies with a larger sample size may be helpful in proving the reliability of the dental age.
