POSSIBLE CAUSES OF ROOT RESORPTION IN ORTHODONTIC TREATMENT

Öz

In this study, the presence and possible causes of external root resorption were investigated by comparing pre- and post-treatment panoramic radiographs. Also, degrees of root resorption were investigated. In this study, external root resorption and its degree were examined in panoramic radiographs of patients who had fixed orthodontic treatment between January 2015 and March 2020. Root resorption was determined in only post treatment panoramic radiographs by comparing pretreatment panoramic radiograph. Anterior and posterior region resorption score of both jaws was calculated for each individual. The relationship between root resorption, age, gender, duration of treatment, types of treatment and malocclusion has been investigated. 560 patients (358 females and 202 males) were included in the study and the average age was 14.2. Root resorption scores of mandibular teeth were higher in males (p<0.01). A positive correlation was found between the treatment duration and root resorption scores of maxillary anterior teeth (p<0.01). Root resorption scores of all regions were higher in orthodontic treatment with extraction (p<0.01). There was no significant relationship between age and root resorption score (p>0.05). Long-term orthodontic treatment and orthodontic treatment with extraction increase the prevalence of root resorption. Panoramic radiograph is an important diagnostic tool in the detection of root resorption due to orthodontic treatment.

ORTODONTIK TEDAVİDE KÖK REZORPSİYONUN OLASI NEDENLERİ

Öz

Bu çalışmada eksternal kök rezorpsiyonunun olası nedenleri, tedavi öncesi ve sonrası panoramic radyograflar karşılaştırılarak araştırılmıştır. Ayrıca kök rezorpsiyonunun derecesi de incelenmiştir. Bu çalışmada, Ocak 2015 ile Mart 2020 yılları arasında sabit ortodontik tedavi gören hastalarda eksternal kök rezorpsiyonu ve derecesi incelenmiştir. Kök rezorpsiyonu, tedavi sonrası panoramic radyografın tedavi öncesi panoramic radyografla karşılaştırılması ile belirlenmiştir. Her hasta için iki çenede ön ve arka gruptaki dişler için rezorpsiyon skoru hesaplanmıştır. Kök rezorpsiyonuyla yaş, cinsiyet, tedavi süresi, tedavi tipi ve maloklüzyon tipi ile arasındaki ilişki araştırılmıştır. Yaş ortalaması 14.2 olan 560 hasta (358 kadın ve 202 erkek) çalışmaya dahil edilmiştir. Erkeklerin mandibular ön dişlerinin kök rezorpsiyon skoru daha yüksektir (p<0.01). Maksiller ön dişlerin rezorpsiyon skoru ile tedavi süresi arasında pozitif korelasyon vardır (p<0.01). Çekimli ortodontik tedavi gören hastalarda tüm bölgelerde rezorpsiyon skoru daha fazladır (p<0.01). Yaş ve rezorpsiyon skoru arasında anlamlı ilişki bulunmamıştır (p>0.05). Uzun süren ortodontik tedavilerde ve çekimli ortodontik tedavilerde kök rezorpsiyon sıklığı artmaktadır. Panoramik radyograflar ortodontik tedavi nedeniyle oluşan kök rezorpsiyonlarının teşhisinde önemli bir tanı aracıdır.
