The Effect of the Anatomical Position of Unilateral Palatinal Impacted Maxillary Canine on Adjacent Lateral Root Resorption

Abstract

Objective: To determine the potential of the anatomical location of unilaterally impacted maxillary canine on panoramic radiographs that cause resorption of the adjacent lateral root.

Material-Method: This study was carried out on the panoramic radiographs of 47 patients, with a unilateral maxillary impacted canine tooth with a mean age of 23.81±6.59 years. In the CBCT recordings, the resorption of the lateral tooth, adjacent to the impacted maxillary canine was determined. The study material was divided into two groups as resorbed and healthy lateral tooth. On panoramic radiographs, the anatomical position of the impacted maxillary canine of a total of 47 individuals, was evaluated using the methods; sector determination, vertical position of the canine crown, angle of the impacted maxillary canine to the occlusal plane, canine follicle width measurement.

Results: Compared to the group with healthy adjacent laterals, the occlusal plane angle of the impacted canine of the individuals with resorbed lateral tooth was higher (p<0.001) and the follicle width was lower (p=0.008). In the individual with resorbed lateral tooth, the angle of the impacted canine tooth to occlusal plane (p=0.001) revealed a significant difference. In the group of patients with resorbed lateral tooth, a significant positive correlation was observed for age and occlusal angle (r=0.449; p=0.028); A significant negative correlation was observed with follicle width (r=0.529; p=0.008).

Conclusion: With panoramic radiographs, impacted maxillary canine and its potential for resorption of adjacent lateral tooth can be determined by measuring the occlusal plane angle and follicle width of the impacted canine.

Tek Taraflı Palatinal Gömülü Maksiller Kanin Dişin Anatomik Konumunun Komşuluğundaki Lateral Diş Kökü Rezorpsiyonu ile İlişkisi

Abstract

Amaç: Panoramik radyograflar üzerinde, palatinalde tek taraflı gömülü maksiller kaninin anatomik konumunun, komşu lateral kökü rezorpsiyonuna sebebiyet verme potansiyelini belirlemektir.

Materyal ve Metot: Bu çalışma tek taraflı maksiller gömülü kanine sahip yaş ortalaması 23,81±6,59 yıl olan toplam 47 hastanın panoramik radyografları üzerinde yürütülmüştür. Çalışmaya dahil edilen bireylerin KIBT kayıtlarında gömülü maksiller kanine komşu lateral dişte rezorpsiyonu belirlenerek, çalışma materyali lateral dişte rezorpsiyonu olan ve lateral dişi sağlıklı olan iki gruba ayrılmıştır. Toplam 47 bireye ait gömülü maksiller kanin anatomik konumu panoramik radyograf üzerinde (a) sektör belirleme, (b) kanin kronunun vertikal pozisyonu, (c) gömülü maksiller kaninin oklüzyon düzlemi ile yaptığı açı, (d) kanin folikül genişliği ölçümü yöntemleri ile değerlendirilmiş, maksiller gömülü kanin dişe komşu lateral dişin rezorpsiyon potansiyeli SPSS 20.0 istatistiksel analiz programı ile analiz edilmiştir.

Bulgular: Komşu laterali sağlıklı olan gruba nazaran lateral diş rezorpsiyonu gözlenen bireylerin gömülü kaninin oklüzal düzlem açısı daha yüksek (p<0,001), folikül genişliği daha düşüktür (p=0,008). Lateral diş rezorpsiyonu gözlenen bireyde gömülü kanin dişin oklüzal düzlem ile yaptığı açı değerleri (p=0,001) anlamlı farklılık göstermiştir. Lateral diş rezorpsiyonu olan hasta grubunda yaş ile oklüzal açı (r=0,449; p=0,028) pozitif yönlü; folikül genişliği (r=0,529; p=0,008) ile negatif yönlü anlamlı korelasyon gözlenmiştir.

Sonuç: Panoramik radyograflar ile sürmesi gecikmiş ya da gömülü kalmış, palatinalde konumlanan maksiller kanin sürme kontrolü ve komşu lateral dişte rezorpsiyon oluşturma potansiyeli gömülü kanin dişin okluzal düzlem açısı ve folikül genişliği ölçümleri ile belirlenebilir.
