MANDİBULAR GÖMÜLÜ KANİNLERİN KONİK IŞINLI BİLGİSAYARLI TOMOGRAFİ İLE AÇISAL, DOĞRUSAL ÖLÇÜMLERİNİN VE DESKRİPTİF ÖZELLİKLERİNİN ÜÇ BOYUTLU ANALİZİ

Amaç: Bu çalışmanın amacı, mandibular gömülü kaninlerin konik ışınlı bilgisayarlı tomografi (KIBT) aracılığı ile lokalizasyon, angülasyon ve deskriptif özelliklerini değerlendirmektir. Gereç ve Yöntem: Çalışmamızda, KIBT görüntülerinde 42 hastada (13 erkek, 29 kadın; ortalama yaşları 20.66 +/– 11.56) toplam 54 mandibular gömülü kanin incelenmiştir. KIBT verileri kullanılarak gömülü kaninlerle ilgili aşağıdaki parametreler analiz edilmiştir: gömülü dişin bulunduğu taraf, lokalizasyon, gömülü kaninlerin oklüzal düzleme ve orta hatta uzaklıkları ile oklüzal düzlem ve orta hat ile yaptığı açılar. Değişkenleri istatistiksel olarak incelemek için Kolmogorov-Smirnov testi ve bağımsız t testi kullanılmıştır. Bulgular: Mandibular gömülü kaninlerin 27’sinin sağda 27’sinin solda lokalize olduğu görülmüştür. 12 örnekte bilateral gömüklük saptanmış, 30 örnekte ünilateral gömülü kanin tespit edilmiştir. Sağ ve sol ünilateral gömülü kaninlerin kronlarının ve apekslerinin oküzal düzleme ve mandibular orta hatta uzaklıkları arasında istatistiksel olarak anlamlı sonuç bulunmamıştır (p=0.07). Aynı şekilde gömülü mandibular kaninlerin orta hat ve oklüzal düzlem ile yaptığı açılar açısından da sağ ve sol taraf arasında anlamlı bir fark ortaya çıkmamıştır (p>0.05). Sonuç: Mandibular kaninlerin sağda ve solda gömülü kalması arasında, gerek oklüzal düzlem ve mandibular orta hatta olan mesafeler gerekse orta hat ve oklüzal düzlem ile meydana gelen açılanmalar açısından istatistiksel olarak anlamlı bir sonuç bulunmamıştır. KIBT ile incelenen gömülü dişlerin açısal ve doğrusal ölçümleri konvansiyonel radyografilere göre daha güvenilir veriler sağlamaktadır.

Material and methods: In our study, cone beam computed tomography scans were examined for 54 mandibular impacted canines among 42 patients. Following impacted canine related parameters were analyzed using CBCT imaging: side of impaction, localization, distance between occlusal plane and midline of impacted canines, and angulation of impacted canines from midline and occlusal plane. A Kolmogorov-Smirnov test and independent statistical t-tests were used to analyze the variables. Results: In total, 27 mandibular impacted canines were located on the right side and 27 on the left side. Bilateral canine impaction was found in 12 subjects, and 30 subjects had sustained unilateral canine impaction. There were no statistically significant differences between midline distances to impacted canine crown tips on the left and right sides compared to other distance parameters (p=0.07); nor were there any statistically significant differences between the angulation of right and left mandibular impacted canines from midline and occlusal plane (p>0.05). Conclusion: Mandibular impacted canines were found more unilateral, labial / buccal localization and found more in women. Linear and angular measurements of impacted mandibular canines, which can provide data for future studies, were obtained through three-dimensional images. Key words: Angular measurements; Cone beam computed tomography; Impacted canine; Linear measurements
