Üçüncü Molar Dişlerde Dental Anomali Görülme Prevelansının Konik Işınlı Bilgisayarlı Tomografi Kullanılarak İncelenmesi

Abstract

Background: Dental anomalies are one of the problems frequently encountered during dental examinations. The aim of this study is to evaluate the frequency of dental anomalies such as transposition, ectopia, microdontia, taurodontism, dilaceration, paramolar teeth, amelogenesis imperfecta and inversion in sex and third molars. Materials and Methods: Cone beam computed tomography (CBCT) images of 2300 patients aged between 12 and 65 years who applied to Hatay Mustafa Kemal University Faculty of Dentistry for various reasons between January 2021 and June 2024 were retrospectively evaluated. While scanning the CBCTs, the sex of the patients and the tooth in which the anomaly was present were noted. All scans were performed by three observers reaching a consensus. Descriptive statistics method was used for statistical analysis. Results:It was observed that the rate of anomalies in all third molars was 10.8%. It was calculated that 54.8% of the individuals with these anomalies were female, 45.2% were male, and the average age was 29.8. It was observed that the most common anomaly in tooth number 18 was ectopia with a rate of 57.14%, the most common anomaly in tooth number 28 was microdontia with a rate of 36.76%, the most common anomaly in tooth number 38 was dilaceration with a rate of 43.9%, and the most common anomaly in tooth number 48 was dilaceration with a rate of 37.72%. It was determined that the most common dental anomaly in women was dilaceration with a rate of 42% and in men was dilaceration with a rate of 57%. Of the anomalies detected, 0.4% were transposition, 11.3% were ectopia, 13.8% were microdontia, 9.3% were taurodontism, 55.48% were dilaceration, 5.89% were paramolar, 2.43% were amelogenesis imperfecta, and 1.2% were inversion. Conclusion: Dilaceration was found to be the most common dental anomaly, most commonly seen in males and in tooth number 38. After dilaceration, microdontia and ectopia are other common anomalies. It was concluded that microdontia and ectopia were most common in females and in tooth number 18.

Investigation of the Prevalence of Dental Anomalies in Third Molars Using Cone Beam Computed Tomography

Abstract

Amaç: Dental anomaliler diş muayeneleri esnasında sıkça karşılaşılan problemlerden biridir. Bu çalışmanın amacı dental anomalilerden; transpozisyon, ektopi, mikrodonti, taurodontizm, dilaserasyon, paramolar diş, amelogenesiz imperfekta ve enversiyonun cinsiyet ve 20 yaş dişlerinde görülme sıklığının araştırılmasıdır. Materyal-Metod: Ocak 2021- Haziran 2024 tarihleri arasında Hatay Mustafa Kemal Üniversitesi Diş Hekimliği Fakültesine çeşitli nedenlerle başvurmuş olan yaşları 12 ile 65 yaş arasında değişen 2300 Konik ışınlı bilgisayarlı tomografileri (KIBT) retrospektif olarak incelenmiştir. KIBT’ler taranırken, hastaların cinsiyeti ve hangi dişte anomali olduğu not edilmiştir. Tüm taramaları üç gözlemci fikir birliğine vararak gerçekleştirmiştir. İstatiksel analiz için tanımlayıcı istatistik yöntemi kullanılmıştır. Bulgular: 20 yaş dişlerinde anomali görülme oranının %10,8 olduğu, bu anomalilere sahip kişilerin %54,8’nin kadın %45,2’sinin erkek olduğu, yaş ortalamasının 29,8 olduğu sonucu elde edilmiştir. 18 numaralı dişte en sık görülen anomalinin%57,14 oranında ektopi, 28 nolu dişte %36,76 oranında en sık görülen anomalinin mikrodonti, 38 numaralı dişte en sık görülen anomalinin %43,9 oranında dileserasyon ve 48 numaralı dişlerde en sık görülen anomalinin ise %37,72 oranında dilaserasyon olduğu görülmüştür. Kadınlarda %42 oranında erkeklerde ise %57 oranında en sık görülen dental anomalinin dilaserasyon olduğu tespit edilmiştir. Tespit edilen anomalilerin %0,4’ü transpozisyon, %11,3’ü ektopi, %13,8’i mikrodonti, %9,3’ü taurodontizm, %55,48’i dilaserasyon, %5,89’u paramolar, %2,43’ü amelogenesiz imperfecta, %1,2’si enversiyon olduğu bulunmuştur. Sonuç: Dilaserasyonun en çok görülen dental anomali olduğu, en çok erkeklerde ve 38 numaralı dişte görüldüğü tespit edilmiştir. Dilaserasyondan sonra mikrodonti ve ektopi de diğer sık görülen anomalilerdendir. Mikrodonti ve ektopi ise en çok kadınlarda ve 18 numaralı dişte görüldüğü sonucuna ulaşılmıştır.
