Three-Dimensional Volumetric Evaluation of Root Canal Filling Performed by Undergraduate Dental Students Using Different Sealers and Obturation Techniques

Abstract

Abstract Objective: The present study aimed to evaluate root canal fillings performed by undergraduate students using different methods with three-dimensional analysis. Methods: Sixty resin-based maxillary central incisors were prepared and randomly assigned to six groups (n=10) according to sealer type (AH Plus/BioRoot RCS/Dia-Root Bio Sealer) and obturation technique (Cold lateral condensation/single cone). Ten senior undergraduate dental students performed one obturation for each combination after training. All samples were scanned with cone-beam computed tomography pre- and post-obturation (CBCT). Mimics medical software was used to calculate pre-obturation canal volume and post-obturation filling volume. The percentage of the obturated volume (POV) was calculated for all samples. Data were analyzed using two-way ANOVA with Tukey and Bonferroni post hoc tests (α=0.05). Results: The type of sealer had a significant effect on POV (p < 0.001), whereas the obturation technique alone was not significant (p = 0.247). AH Plus showed significantly higher POV values compared to both BioRoot RCS and Dia-Root Bio Sealer (p < 0.05), while no significant difference was observed between BioRoot RCS and Dia-Root Bio Sealer. However, a significant interaction was found between the type of sealer and the obturation technique (p = 0.008). Dia-Root Bio Sealer achieved higher POV when used with the single-cone technique compared to cold lateral condensation (p = 0.033). Conclusion: AH Plus demonstrated high filling percentages when applied with both SC and CLC techniques in root canal fillings performed by undergraduate students. The lower filling percentages observed with BioRoot RCS and DiaRoot Bio Sealer highlight the need for enhanced training and supervision during the educational process.

Diş Hekimliği Öğrencileri Tarafından Farklı Kanal Patları ve Obturasyon Teknikleri Kullanılarak Yapılan Kök Kanal Dolgularının Üç Boyutlu Volümetrik Değerlendirmesi

Abstract

Özet Amaç: Bu çalışmanın amacı, diş hekimliği öğrencileri tarafından farklı yöntemlerle yapılan kök kanal dolgularını üç boyutlu analizle değerlendirmektir. Yöntem: Altmış adet rezin maksiller santral diş hazırlanarak rastgele altı gruba (n=10) ayrılmıştır. Gruplar kanal patı türüne (AH Plus / BioRoot RCS / Dia-Root Bio Sealer) ve obturasyon tekniğine (soğuk lateral kondensasyon / tek kon tekniği) göre oluşturulmuştur. On adet son sınıf diş hekimliği öğrencisi, eğitim aldıktan sonra her kombinasyon için bir obturasyon gerçekleştirmiştir. Tüm örnekler obturasyon öncesi ve sonrası konik ışınlı bilgisayarlı tomografi (CBCT) ile taranmıştır. Mimics Medical yazılımı kullanılarak obturasyon öncesi kanal hacmi ve obturasyon sonrası dolgu hacmi hesaplanmıştır. Her örnek için dolgu hacmi yüzdesi (POV) hesaplanmıştır. Veriler iki yönlü ANOVA ve Tukey ile Bonferroni post-hoc testleri kullanılarak analiz edilmiştir (α = 0.05). Bulgular: Kanal patı türü, POV üzerinde anlamlı bir etkiye sahiptir (p < 0.001), ancak obturasyon tekniği tek başına anlamlı değildir (p = 0.247). AH Plus, hem BioRoot RCS hem de Dia-Root Bio Sealer’a göre anlamlı derecede daha yüksek POV değerleri göstermiştir (p < 0.05). BioRoot RCS ile Dia-Root Bio Sealer arasında anlamlı fark gözlenmemiştir. Ancak kanal patı türü ile obturasyon tekniği arasında anlamlı bir etkileşim bulunmuştur (p = 0.008). Dia-Root Bio Sealer, tek kon tekniği ile uygulandığında soğuk lateral kondensasyona göre daha yüksek POV elde etmiştir (p = 0.033). Sonuç: AH Plus, diş hekimliği öğrencileri tarafından gerçekleştirilen kök kanal dolgularında hem tek kon hem de soğuk lateral kondensasyon tekniklerinde yüksek dolum yüzdeleri göstermiştir. BioRoot RCS ve Dia-Root Bio Sealer ile elde edilen daha düşük dolum yüzdeleri, eğitim sürecinde ek uygulama ve gözetimin önemini ortaya koymaktadır.
