Abstract

Amaç: Bu çalışmada, Türkiye’deki 5-15 yaşları arasındaki çocuklarda üçüncü büyük azı dişlerinin kron kalsifikasyonunun başlama yaşının belirlenmesi ve bu dişlerin gelişim durumlarının yaşa göre değerlendirilmesi amaçlanmıştır.

Gereç ve Yöntemler: Çalışmamızda, 5-15 yaş aralığındaki ilk 1024 hastanın panoramik radyografileri değerlendirilmiştir. Üçüncü molar dişlerinin gelişimi Demirjian metoduna göre sınıflandırılmıştır.

Bulgular: Maksiller ve mandibular üçüncü molarların gelişim evrelerinin başlangıç yaşları karşılaştırıldığında istatistiksel olarak anlamlı bir fark bulunamamıştır (p≥0.05). Ayrıca üçüncü büyük azı dişleri, kalsifikasyon başlangıç yaşı açısından değerlendirildiğinde cinsiyetler arasında istatistiksel olarak anlamlı bir fark bulunmamasına rağmen 28 ve 48 numaralı dişlerin erkeklerde kızlardan yaklaşık bir yıl önce geliştiği görülmüştür (p≥0.05). Maksiller ve mandibular üçüncü molar dişlerin gelişim evrelerinin başlangıç yaşları karşılaştırıldığında istatistiksel olarak anlamlı bir fark bulunmamıştır (p≥0.05). Üçüncü moların furkasyon kalsifikasyon derecesinin gösteren stage 5 evresi, maksiller ve mandibular molar dişlerde kızlarda erkeklerden daha erken yaşlarda görülmüştür.

Sonuç: Sağ taraftaki maksiller üçüncü molarların mandibular üçüncü molarlara göre daha erken geliştiği görülmüştür.

RADIOGRAPHIC EVALUATION OF THE DEVELOPMENT OF THIRD MOLARS IN CHILDREN AGED 5-15 IN TURKEY

Abstract

Objective: In this study, it was aimed to determine the age of the onset of crown calcification of third molars in children aged 5-15 years in Turkey, and to evaluate the development status of third molars by age.

Material and Methods: Panoramic radiographs of the first 1024 patients between the ages of 5 and 15 years were evaluated. The development (calcification) of third molars was classified according to the Demirjian method.

Results: When the onset age of the stages for maxillary and mandibular third molars were compared, no statistically significant difference was found (p≥0.05). In addition, although no statistically significant difference was found between genders regarding the age of calcification onset of third molars, it was observed that teeth #28 and #48 developed in boys approximately one year before girls (p≥0.05). When the onset age of the stages for maxillary and mandibular third molars were compared, no statistically significant difference was found (p≥0.05). Concerning stage 5, in which the furcation zone of third molars begins to calcify, although not statistically significant, all the maxillary and mandibular third molars were seen earlier in girls than boys.

Conclusion: It was found that the maxillary third molars on the right side developed earlier than mandibular third molars.
