Tek kon yönteminin apikal sızıntıyı engelleme yeteneğinin 3 farklı

Amaç: 3 farklı döner sistem ile şekillendirilen kanallarda tek kon yönteminin apikal sızıntıyı engelleme yeteneğinin değerlendirilmesi. Gereç ve Yöntem: Elli-dört adet üst lateral kesici diş mine-sement sınırından ya da bu sınırın altından köklerin boyları 13 mm olacak şekilde kesildi. Bu kökler rastlantısal olarak her biri 12 örnek içerecek şekilde 4 deney grubuna ve 2 kontrol grubuna ayrıldı (n=3). Grup I: Step-back + Lateral kompaksiyon, Grup II: ProTaper (Tek kon yöntemi), Grup III: Mtwo (Tek kon yöntemi), Grup IV: K3 (Tek kon yöntemi). Gütaperka konlar ile birlikte AH Plus kök kanal patı kullanıldı. Kanal dolguları tamamlandıktan sonra örnekler 1 hafta boyunca 37 °C’de % 100 nemli ortamda bekletildi. Sızıntı sıvı filtrasyon yöntemi ile ölçüldü ve Lp olarak belirlendi. Sonuçlar One-way ANOVA ve Tukey testleri kullanılarak değerlendirildi. Bulgular: Yapılan istatistiksel analiz gruplar arasında fark olmadığını gösterdi (P > .05). Tek kon yöntemi ve lateral kompaksiyon yöntemi kullanılarak doldurulan örnekler benzer sızıntı değerleri gösterdi. Sonuç: Bu çalışmada değerlendirilen tüm Tek kon yöntemleri, apikal sızıntıyı engellemekte geleneksel step-back + lateral kompaksiyon yöntemi kadar etkilidir.

Apical sealing ability of single-cone technique in canals shaped with three different rotary systems

Background: To evaluate the apical sealing ability of single-cone technique in canals shaped with three different rotary systems. Methods: Fifty-four maxillary lateral incisor teeth were sectioned at or below the cemento-enamel junction to obtain roots of 13 mm. These roots were randomly divided into four experimental groups (n=12) and two control groups (N=3); GI: Step-back + Lateral condensation, GII: ProTaper (Single-cone) GIII: Mtwo (Single-cone) GIV: K3 (Single-cone). AH Plus sealer was used along with guttapercha points. After the completion of root fillings, the specimens were stored for 1 week at 37 °C and 100% humidity. Leakage was measured using the fluid filtration method and determined as &#956;L/ min. Results were assessed with statistical analysis using One-way ANOVA and Tukey tests with a significance level of P < .05. Results: The statistical analysis showed no statistical difference among the groups (P > .05). Three single-cone groups and lateral condensation technique exhibited similar levels of leakage. Conclusion: The three single-cone groups were found as effective as step-back + lateral condensation technique group in terms of apex sealing.
