Effectiveness of Ultrasonic Activation of Endosequense BC Sealer and the Type of Gutta-Percha Pointon the Root Canal Filling Quality (An In-Vitro Study)

Objectives: This study aims to evaluate the effectiveness of ultrasonic activation and BC gutta-percha points in the obturation of root canals. Materials and Methods: The study sample consisted of 40 single rooted lower premolars extracted for orthodontic reasons. Root canal treatment was done after decoronation and equalization the length of the roots. The sample was divided randomly into four groups (n = 10) depending on whether or not ultrasonic activation used and the type of gutta-perhapoints: group 1: ultrasonic activation used for EndoSequence BC sealer are used with traditional gutta-percha (UAGP), group 2: ultrasonic activation used for EndoSequence BC sealer are used with BC gutta-percha (UABC), group 3: ultrasonic activation was not used for BC sealer with traditional gutta-percha (NAGP). group 4: ultrasonic activation was not used with BC gutta-percha (NABC). After filling the teeth, a microleakage test with 2% methylene blue was performed for all samples. Then, all samples were studied on a 20X stereomicroscope after clearing them. The data was subjected to statistical analysis using one-way ANOVA Test with a p value (p<0.05) and the confidence level (95%). Results: There were statistically significant differences in the average amount of microleakage (mm) between the filling groups with ultrasonic activation and the non-activation groups. While using endosequence BC points showed no significant differences. Conclusion: Ultrasonic activation of EndoSequence BC sealer improves root filling quality and reduces microleakege percentage. While using endosequence BC points showed no reduction in the microleakage level.
