Evaluation of Different Root Canal Filling Methods in Primary Teeth

Objective: To compare the efficacy of 5 different methods for filling primary teeth root canals by digital radiography. Materials and Methods: A total of 50 extracted primary anterior teeth with no more than 25% root resorption were prepared using Mtwo® NiTi rotary instruments to a standard apical file size. Teeth were randomly divided into 5 groups, as follows according to the sealer application method. Group 1: Metapex® syringe (control); group 2: Metapex® syringe and Endoactivator® (sonic activation); group 3: Metapex® syringe and indirect ultrasonic activation; group 4: Endodontic irrigation needle; group 5: Lentulo spiral. Photostimulated phosphor radiographs of canals were evaluated for length of filling (underfilled, suboptimally filled, optimally filled, overfilled) and quality of filling (presence, localization and total sum of voids). Data was statistically analyzed using Kruskal-Wallis and Bonferroni-corrected MannWhitney U tests. Results: For the both length and the quality of the filling the worse results were seen in the endodontic irrigation needle group (group 4) (p0.05). Conclusion: Based on the results of this study apart from the endodontic irrigation needle group, all the tested methods could be used for obturation of primary teeth.

Amaç: Süt dişleri kök kanallarının dolumu için kullanılan beş farklı metodun etkinliğinin dijital radyografi yöntemiyle karşılaştırılmasıdır. Gereç ve Yöntemler: Çalışmada kök rezorpsiyonu %25’ten fazla olmayan toplam 50 adet çekilmiş süt ön diş kullanıldı. Dişler, Mtwo® NiTi döner aletler kullanılarak standart bir apikal genişlik elde edilecek şekilde hazırlandı. Dişler rastgele 5 gruba ayrıldı: grup 1: Metapex® şırınga (kontrol); grup 2: Metapex® şırınga ve Endoaktivatör® (sonik aktivasyon); grup 3: Metapex® şırınga ve indirekt ultrasonik aktivasyon grup 4: Endodontik irrigasyon iğnesi; grup 5: Lentulo spiral. Kanalların fosfor plakla alınmış radyografik görüntüleri ile kanal dolgusunun uzunluğu (yetersiz, ideale yakın, ideal ve taşkın dolgu) ve kalitesi (boşlukların varlığı, lokalizasyonu ve toplam alanı) değerlendirildi. Veriler istatistiksel olarak KruskalWallis ve Bonferroni-düzeltmeli Mann-Whitney U testleri kullanılarak analiz edildi. Bulgular: Kök kanal dolumları hem uzunluk hem de kalite anlamında değerlendirildiğinde en kötü sonuçlar endodontik irrigasyon iğnesi grubunda elde edildi (grup 4) (p0,05). Sonuç: Çalışmanın sonuçlarına göre; endodontik irrigasyon iğnesi grubu dışında tüm test edilen yöntemler süt dişlerinin kanal dolgusu sırasında kullanılabilir.
