| Summary: | Aim:
This study aimed to assess the effectiveness of several irrigation techniques, including side-vented needles, air-sonic, and ultrasonic methods, in penetrating the dentinal tubules of root canals with sodium hypochlorite (NaOCl).
Methods:
“Seventy-five fully developed, permanent premolars on the lower jaw with a single root canal were assigned by simple randomization by chit picking method to three groups: Group A – irrigation with 30-gauge side-vented needles, Group B – air sonic irrigation, and Group C – passive ultrasonic irrigation done with NaOCl, positive control group and negative control group. After 72 h of submerging the root canals in crystal violet, the bleaching impact of NaOCl will be measured under a stereomicroscope.
Results:
Data were analyzed using the Kruskal–Wallis test. One-way analysis of variance test was used to study the differences in NaOCl penetration using conventional needle irrigation and sonic and ultrasonic irrigation in coronal, middle, and apical third. The level of significance and confidence of the interval were set at 5% (P < 0.05) and 95%, respectively. In the coronal section, maximum penetration depth was seen in the conventional needle group and least in the sonic group (P < 0.05). In the middle section and apical sections, the maximum penetration depths were seen in the sonic group which was statistically significantly different from the other two groups.
Conclusion:
“Irrigation methods impact the depth to which NaOCl penetrates dentinal tubules in root canals. The penetration of NaOCl into root canal dentinal tubules can be enhanced using the sonic irrigation approach in the apical third. |
