Evaluating the influence of different irrigation needles on the apical cleaning efficacy of endodontic irrigation - An study.

CONTEXT

Irrigation is an essential part of a successful root canal treatment.

AIM

This study evaluates and compares the influence of three different double-sided vented irrigation needle gauges (G) (27G, 30G, and 31G) on the apical cleaning effectiveness of endodontic irrigation using radiovisiography.

SETTINGS AND DESIGN

A thorough protocol describing the objectives and methodologies of the study was submitted to the Institutional Ethics Committee, Vivekanandha Dental College for Women. Ethical clearance no. VDCW/IEC/340/2023.

SUBJECTS AND METHODS

Forty-five human mandibular premolars were extracted, filled with a radiopaque medium, and subjected to irrigation with three varying sizes of double-sided vented irrigation needles. Preirrigation and postirrigation radiographic images were digitally subtracted to assess the cleaned areas.

STATISTICAL ANALYSIS USED

Statistical analysis was carried out with SPSS version 27. For the purpose of intergroup comparisons, one-way analysis of variance was implemented, followed by the execution of the Tukey honestly significant difference post hoc test. Throughout the comparisons, < 0.05 was deemed statistically significant.

RESULTS

Maximum cleaning was observed in 31G double-sided vented irrigation needles, followed by 30G and 27G double-sided vented irrigation needles.

CONCLUSIONS

The 31G double-sided vented irrigation needles exhibit a higher level of effectiveness in the cleansing of the apical third of the root canal system in comparison to the other two irrigation needle variants.
