Aim: The aim of this study was to determine the incidence and the severity of the apical tooth resorption which occurs during orthodontic treatment. A further aim was to investigate the distribution of the resorptions among tooth groups and the influence of treatment duration, type of treatment and gender on apical root resorption.Material and Method: The materials of this study consisted of the pre- and post treatment digital panoramic radiographs of 120 patients 81 girls, 39 boys . After elimination of 6 radiographs that showed poor image quality on incisor region and 3 removable appliance treatments, the remaining pre- and post treatment radiographs that belong to 111 patients were investigated by the same investigator. All of the permanent teeth except for the third molars were investigated for apical root resoption. The results were evaluated statistically. Results: The apical root resorption was seen most frequently on maxillary central and lateral incisors. The maxillary incisors were followed by the mandibular incisors and the mandibular premolars. No differences for gender and treatment type were found on the apical root resorption incidence in the investigated group. Increase in treatment duration increases the risk for resorption. Conclusion: While the maxillary and the mandibular incisors showed the most frequent rate of apical root resorption, it is recommended to take periapical radiographs from these regions regularly during treatment

Ortodontik Tedavi Sırasında Görülen Kök Rezorpsiyonu’nun İncelenmesi

Öz

Amaç: Bu çalışmanın amacı ortodontik tedavi ile oluşan kök rezorpsiyonunun insidansını ve şiddetini belirlemek, görülen rezorpsiyonların dişlere göre dağılımını yapmak, tedavi süresi, tedavi türü ve cinsiyetin etkilerini incelemektir. Materyal Metot: Kök rezorpsiyonlarını belirleyebilmek amacıyla, ortodonti kliniği arşivinden 120 81 kız, 39 erkek hastaya ait, tedavi başında ve sonunda alınan panoramik radyograflar belirlenmiştir. Hastaların, keser bölgesinde görüntü kalitesi iyi olmayan 6 radyograf ve hareketli tedavi gören 3 hastanın radyografları çalışmadan çıkartıldıktan sonra kalan 111 79 kız, 32 erkek hastanın başlangıç ve bitiş panoramik radyograflarında 3. molarlar hariç tüm dişlerde görülen kök rezorpsiyonları aynı araştırıcı tarafından incelenmiştir. Elde edilen sonuçlar istatistiksel olarak Fisher kesin t-testi ile değerlendirilmiştir. Bulgular: Apikal kök rezorpsiyonu en sık maksiller santral ve lateral dişlerde görülmüştür. Maksiller keserleri mandibular keserler ve mandibular premolarlar izlemiştir. İncelenen grupta cinsiyet ve tedavi tipinin apikal kök rezorpsiyonu üzerinde etkili olmadığı, tedavi süresinin artması ile apikal kök rezorpsiyonu insidansının arttığı bulunmuştur. Sonuç: Tedavi sırasında en çok maksiller ve mandibular keser dişlerde apikal kök rezorpsiyonu görülmesi nedeniyle tedavi sırasında bu dişlerden belirli aralıklarla periapikal radyograf alınması önerilir. Ayrıca rezorpsiyon oranının artmaması için tedavi süresinin uzatılmaması gereklidir.
