(PR039) Efficacy of Light Cured Root Canal Obturation Material: An In Vitro Study

Objectives: The present study aims to evaluate the efficacy of the newly introduced light cure obturation material OdneFill, compared to conventional endodontic sealers such as Endo-Sequence BC Sealer and AH Plus. Understanding endodontic sealers’ biological and physiochemical properties is essential for assessing the effectiveness of the obturation. Additionally, the techniques for obturating root canals with these materials will be examined to analyze their performance comprehensively. Experimental

Methods: This study employed 3-D printed #19 molar models, with Mesio-Buccal and Mesio-Lingual canals prepared to a 20/.04 size. Irrigation was performed using a total of 10 mL of NaOCl and EDTA. Obturations were conducted on thirty teeth, ten teeth each with BC Sealer, AH Plus, and OdneFill. Radiographs were taken following instrumentation, pre- and post-obturation, utilizing a custom-designed VPS putty apparatus to standardize conditions. Radiographic parameters were set at 70 kV, 10 mA, and 0.54 seconds.

Results: The interaction of OdneFill with NaOCl in prepared canals led to the formation of a precipitate, necessitating a rinse with 5 mL of water. Thus, prior drying of canals with paper points is essential to prevent precipitate formation. Due to its hydrophilic nature, OdneFill requires moisture to maintain stability. Although apical condensation and overall fill with OdneFill were satisfactory, minor distortions occurred from the curing tip. In contrast, Endo Sequence BC Sealer displayed a denser fill with fewer voids than AH Plus within the root canal system.

Conclusion: The results indicate that OdneFill as an obturating material is promising; however, additional studies are required to evaluate its effectiveness further in clinical settings.
