# Analysis of fracture resistance in teeth obturated with graphene oxide-modified sealers

## TL;DR

Adding graphene oxide to dental sealers improves tooth fracture resistance after root canal treatment.

## Contribution

Graphene oxide-modified sealers significantly enhance structural reinforcement in treated teeth.

## Key findings

- Teeth with graphene oxide-modified sealers showed 530 ± 22 N fracture resistance.
- GO-modified sealers outperformed regular and calcium silicate-based sealers (p < 0.05).
- GO addition reduces fracture risk and improves treatment outcomes in root canals.

## Abstract

Analysis of tooth resistance after obtaining them with regular sealers in addition to calcium silicate based ones and graphene oxide
modified versions is of interest. Hence, 3 groups containing sixty premolars underwent universal testing machine evaluation. The mean
fracture resistance value for teeth treated with graphene oxide (GO)-modified sealer reached 530 ± 22 N in Group 3 which resulted
in significantly better results than the other tested groups (p < 0.05). We show that GO-added sealers lead to superior structural
reinforcement for teeth which have undergone root canal treatment. Introducing GO into endodontic treatment regimens would lower the
risk of fractures and result in better treatment performance.
