Abstract

Taurodontism is a morphological anomaly of teeth characterized with largepulp chambers and apically displaced pulpal floor. The aim of this case reportwas to make a comparative evaluation by panoramic radiographies and 3Dexaminations to locate pulp chamber and root canal morphology of a primarymandibular first molar and the adaptation of root canal filling material of apermanent mandibular first molar, both diagnosed with taurodontism. In Case1, a mandibular primary first molar was extracted due to physiological rootresorption seen in the panoramic radiograph. The micro-CT (Bruker, SkyScan1174, Belgium) examined the distance of the tooth a (distance between thelowest and the top point of the pulp chamber) and b (distance between thelowest point of the pulp chamber and the apical). The tooth was classified asmesotaurodont by the value of 52.91 obtained with the formula a/b x 100. InCase-2, the tooth was extracted because of the large periapical radiolucencyobserved in the radiography taken from the tooth which was admitted for painand percussion tenderness. The calculation for subgroup could not beperformed due to loss of the “a” value because of the cavity preparation.Although the root canal filling on the radiograph was found to be sufficientand long enough, an empty extra canal and insufficient wall adaptation of rootcanal filling were detected by micro-CT. Despite the fact that taurodontism canbe diagnosed by 2D measurements, it is obvious that a 3-dimensionalexamination is necessary to obtain decisive data about the root canal cavitymorphology especially for endodontic treatment and also to define prevalenceand subgroups of anomalies. Although micro-CT is seen as a method thatprovides more detailed images, it is thought that it should be developed andsupported with clinical studies in order to be valid and easy to use in clinicalpractice.

Özet

Taurodontizm pulpa odası tabanının apikale doğru yer değiştirmiş olması ile karakterize morfolojik bir dental anomalidir. Bu olgu bildirisinde radyografik olarak taurodontizm tanısı konulan ve çekim endikasyonu olan süt 1.azı ve daimi 1.büyük azı dişinin pulpa odası ve kök kanallarının mikro-CT ile değerlendirilmesinin sunumu amaçlanmıştır. Olgu 1’de, radyografik muayenesinde fizyolojik kök rezorbsiyonu olduğu görülen sol alt süt birinci azı dişin çekimi uygun görülmüştür. Mikro-CT (Bruker, SkyScan 1174, Belgium) ile incelenen dişin a (pulpa odası tavanının en alt noktası ve tabanının en üst noktası arasındaki mesafe) ve b (pulpa odası tavanının en alt noktası ile apikal arasındaki mesafe) mesafeleri hesaplanmıştır. Olgu 1’deki dişte a/b x 100 formülüyle elde edilen 52,91 sayısal verisine göre süt azı dişi mesotaurodont olarak sınıflandırılmıştır. Olgu 2’de alt sağ daimi birinci büyük azı dişinde ağrı ve perküsyonda hassasiyet nedeniyle başvuran hastadan alınan radyografide geniş periapikal radyolusensi gözlendiği için dişin çekimi uygun görülmüş ve mikro-CT (Bruker, SkyScan 1174, Belgium) ile kök kanal morfolojisi incelenmiştir. Dişin kavite preperasyonu sonucunda a değeri kaybedildiği için hesaplama yapılamamıştır. Alınan radyografide kanal dolgusunun kök boyu itibariyle yeterli ve olması gereken uzunlukta olduğu belirlenmesine karşın mikro-CT’den elde edilen kesitsel görüntülerde ise kanal dolumu yapılmamış ekstra bir kanal boşluğu ve özellikle distal kanalın kesitinin oldukça eliptik olduğu tespit edilmiştir. 2 boyutlu radyografilerle taurodontizm tanısı konulabilmesine rağmen özellikle endodontik tedavi endikasyonu olan dişlerde kök kanal boşluğu morfolojilerinin 3 boyutlu olarak incelenmesi gerekliliği görülmektedir. Mikro-CT daha detaylı görüntüler sağlayan bir yöntem olarak görülmekle birlikte klinik kullanımda geçerliliği ve uygulama kolaylığı olacak şekilde geliştirilmesi ve klinik çalışmalarla desteklenmesi gerektiği düşünülmektedir.
