# Effect of Triton all-in-one irrigant on electronic working length determination using two apex locators: an in vitro study

## TL;DR

This study tested if a new all-in-one irrigant, Triton, affects the accuracy of measuring root canal length with electronic devices.

## Contribution

The study introduces Triton as a potential time-saving irrigant that does not compromise apex locator accuracy.

## Key findings

- Triton showed no significant difference in accuracy compared to traditional irrigants.
- Dry canals resulted in significantly longer electronic measurements than actual lengths.
- Both apex locators performed similarly across all conditions.

## Abstract

This study evaluated whether Triton, a newly introduced all-in-one irrigant, affects the accuracy of electronic working length determination, and compared two electronic apex locators (Ai-Pex, Propex Pixi) under different irrigant conditions.

Forty-four extracted single-rooted human teeth were embedded in alginate. Actual working length was determined under a dental operating microscope. Specimens were assigned to four groups (Triton, 17% ethylenediaminetetraacetic acid, 10% citric acid, dry canal). Electronic working lengths were measured with Ai-Pex and Propex Pixi using #15 K-files. Statistical analyses were performed using one-way and two-way analysis of variance (ANOVA) following normality assessment, with statistical significance set at p < 0.05.

No significant differences occurred among Triton, ethylenediaminetetraacetic acid, and citric acid groups (p > 0.05). Dry canal measurements were significantly longer than the actual working length measured under a dental operating microscope (p < 0.05). Both apex locators showed comparable accuracy.

Triton did not reduce apex locator precision, supporting its potential as a time-saving irrigant that permits simultaneous irrigation and measurement. Further clinical validation is required.
