Objective: To compare the dentoalveolar measurements of the subjects with unilateral palatally impacted canines versus nonimpacted contralateral side on cone-beam computed tomography. Material and Methods: This retrospective study comprised 27 patients (16 female, 11 male; mean age: 15.34±1.95 years) with unilateral palatally impacted canine. Dolphin imaging software was used to reconstruct coronal, sagittal, and axial images. Coronal images were used for the evaluation of the angulation of the canine and lateral teeth, dentoalveolar height from the central and lateral incisors. On sagittal images, canine, lateral, first premolar angulation, and the distance of the canine cusp tip to the occlusal plane, on axial images; the lateral incisor rotation and arch width from premolar to mid-palatine raphe were evaluated. The paired samples t-test and Pearson correlation analysis were used for the statistical evaluation. Results: Lateral incisors on the impacted side showed significantly higher coronal angulation and lower sagittal angulation, compared to the non-impacted side (p<0.05). On impacted side, axial width from the first premolar to the mid-palatine raphe and lateral incisor rotation was significantly lower than on the non-impacted side (p≤0.001). Canine cusp tip-occlusal plane was negatively correlated with the dentoalveolar height of the central (r=-0.400; p=0.039) and lateral incisors (r=-0.373; p=0.055). Conclusion: The results of the study implicate that unilateral palatally impacted maxillary canines can provide asymmetric dentoalveolar measurements. The deviation of the lateral incisors from normal angulation should be taken into consideration during orthodontic examination.

Amaç: Çalışmanın amacı, konik ışınlı bilgisayarlı tomografi kullanılarak tek taraflı palatal gömülü kanine sahip bireylerin dentoalveolar ölçümlerinin, gömülü kanin olmayan karşı taraf ile karşılaştırılmasıdır. Gereç ve Yöntemler: Retrospektif dizaynlı çalışmamız, tek taraflı maksiller palatal gömülü kanine sahip 27 bireyi (16 kadın, 11 erkek; ortalama yaş: 15,34±1,95 yıl) içermektedir. Dolphin yazılım programı kullanılarak koronal, sagital ve aksiyel kesitler elde edilmiştir. Koronal görüntülerde; lateral ve kanin dişlerin açılanmaları, santral ve lateral dişlerin dentoalveolar yükseklikleri ölçülmüştür. Lateral, kanin ve 1. premolar dişlerin sagital açılanmaları ve kanin tüberkülünün okluzal düzleme olan mesafesinin ölçümü sagital görüntüler kullanılarak yapılmıştır. Lateral diş rotasyonu ve pre-molar-midpalatal sütur arası genişlik ölçümleri aksiyel görüntüler üzerinde yapılmıştır. Eşleştirilmiş örneklem-t-testi ve Pearson korelasyon analizi istatistiksel değerlendirmede kullanılmıştır. Bulgular: Gömülü taraftaki lateral kesiciler, gömülü olmayan tarafa göre daha yüksek koronal açılanma ve daha düşük sagital açılanma değeri göstermiştir (p<0,05). Gömülü segmentte 1. premolar diş ile midpalatal sütur arası aksiyel genişlik ve lateral dişin rotasyonu karşı tarafa kıyasla daha düşük bulunmuştur (p≤0,001). Kanin tüberkülünün okluzal düzleme olan dikey mesafesi ile santral (r=-0,400; p=0,039) ve lateral kesicilerin (r=-0,373; p=0,055) dentoalveolar yükseklikleri arasında negatif korelasyon saptanmıştır. Sonuç: Bu çalışmanın sonuçları tek taraflı palatal maksiller gömülü kaninlerin asimetrik dentoalveolar ölçümlere neden olabileceğini vurgulamaktadır. Lateral kesici dişlerin normal açılanmadan sapma göstermesi ortodontik muayene sırasında dikkate alınmalıdır.
