# Evaluation of surface roughness and nano hardness in root dentin on exposure to different irrigating agents - An in vitro study

## TL;DR

This study compares how different dental cleaning solutions affect the texture and hardness of root dentin in teeth.

## Contribution

The study introduces a novel comparison of Chloroquick's effects on dentin properties relative to traditional irrigants.

## Key findings

- Chloroquick caused the highest surface roughness in root dentin.
- Chloroquick had the greatest impact on nano hardness and modulus of elasticity of dentin.
- Saline showed the least effect on dentin properties compared to other solutions.

## Abstract

Root dentin integrity can be altered by various endodontic irrigants, potentially influencing long-term treatment outcomes. Therefore,
it sis of interest to evaluate the effects of different irrigating solutions on the surface roughness and nano hardness of root dentin in
60 extracted maxillary central incisors. Specimens were treated with normal saline, sodium hypochlorite, EDTA + NaOCl, or Chloroquick,
followed by surface and nano-mechanical analysis. Chloroquick demonstrated the highest surface roughness, nano hardness, and modulus of
elasticity, followed by EDTA+NaOCl, NaOCl, and saline. Thus, Chloroquick caused the greatest dentin alterations compared with other
irrigants.
