# Endodontics - Orthodontics correlation: Inside and outside the root

## TL;DR

This paper explores how root canal-treated teeth respond differently to orthodontic forces compared to healthy teeth, offering insights for better treatment planning.

## Contribution

The study identifies key predictors of complications in combined endodontic and orthodontic treatments.

## Key findings

- Root canal-treated teeth show lower root resorption rates than vital teeth under orthodontic forces.
- Stress distribution and complications vary, requiring careful treatment planning.
- Orthodontic force, treatment duration, and obturation quality are critical predictors of outcomes.

## Abstract

The relationship between endodontics and orthodontics focusing on root canal-treated teeth under orthodontic forces is of interest.
Lower root resorption rates in treated teeth compared to vital teeth were observed. Stress distribution and complications varied,
emphasizing the need for careful multidisciplinary treatment planning. Regression analysis identified orthodontic force, treatment
duration and obturation quality as critical predictors. The findings guide clinicians in optimizing outcomes for combined endodontic and
orthodontic treatments.
