Abstract

Objective: To evaluate the relationship between radiographic measurements obtained from panoramic images and root resorption of neighboring teeth in patients presenting with a unilateral impacted maxillary canine, with cone-beam computed tomography (CBCT) serving as the gold standard. Materials and Methods: 88 Caucasian patients with unilateral maxillary impacted canines were included. Panoramic parameters, including canine angulation relative to the midline, occlusal plane, and lateral incisor, sector classification, perpendicular distance to the occlusal plane (d distance), and primary canine retention, were measured. Root resorption was assessed using CBCT. Associations were analyzed using univariate tests, binary logistic regression, and receiver operating characteristic (ROC) curve analysis, with significance set at p 0.05). The d distance was confirmed as a significant independent predictor in the logistic regression model (OR=1.184, p=0.024), with ROC curve analysis establishing an optimal d distance cut-off of 11.2 mm (AUC=0.698), whereas patient age did not retain significance (p>0.05). Although the regression model indicated a marginally lower risk for Sector III compared to Sector I, overall sector classification did not demonstrate standalone predictive value (p>0.05). Conclusion: The d distance was the only parameter that independently predicted adjacent root resorption, with a distance of 11.2 mm found to be a potentially clinically useful threshold that may support selective referral for CBCT in high-risk cases.

Özet

Amaç: Tek taraflı maksiller gömülü kanin dişi olan hastalarda, konik ışınlı bilgisayarlı tomografi (KIBT) referans standart olarak kullanılarak, panoramik radyografik parametreler ile komşu dişlerin kök rezorpsiyonu arasındaki ilişkinin araştırılmasıdır. Gereç ve Yöntemler: Bu retrospektif çalışmaya, tek taraflı maksiller gömülü kanin dişi olan 88 hasta dahil edilmiştir. Kanin dişin orta hat, lateral kesici diş ve oklüzal düzleme göre angulasyonu, sektör sınıflandırması, oklüzal düzleme olan uzaklığı (d mesafesi) ve süt kanin dişin retansiyonu gibi panoramik parametreler ölçülmüştür. Kök rezorpsiyonu KIBT kullanılarak değerlendirilmiştir. İlişkiler tek değişkenli testler, ikili lojistik regresyon ve alıcı işletim karakteristiği (ROC) eğrisi analizi kullanılarak analiz edilmiş olup anlamlılık düzeyi p 0,05). Lojistik regresyon modelinde, d mesafesi anlamlı bir bağımsız öngörücü (OR=1,184, p=0,024) olarak doğrulanmış ve ROC eğrisi analizi ile optimum d mesafesi kesme (cut-off) değeri 11,2 mm (AUC=0,698) olarak belirlenmiştir. Öte yandan hasta yaşı anlamlılığını koruyamamıştır (p>0,05). Regresyon modeli Sektör I'e kıyasla Sektör III için marjinal olarak daha düşük bir risk belirtmesine rağme, genel sektör sınıflandırması tek başına öngörücü bir değer göstermemiştir (p>0,05). Sonuç: d mesafesi, komşu kök rezorpsiyonunu bağımsız olarak öngören tek parametre olmuş olup, 11,2 mm'lik mesafenin yüksek riskli vakalarda KIBT'ye seçici yönlendirmeyi destekleyebilecek potansiyel olarak klinik açıdan faydalı bir eşik değer olduğu bulunmuştur.
