Splinting in horizontal root fractures: A Bayesian network meta-analysis

TL;DR

This study finds that the type of splint used for horizontal root fractures may not affect healing outcomes, with displacement being a more important factor.

Contribution

The study uses a Bayesian network meta-analysis to compare splinting methods for horizontal root fractures.

Findings

No significant differences were found between splint types for healing outcomes.

Fragment displacement was a key factor influencing prognosis.

Other treatment-related variables also affected tooth outcomes.

Abstract

This study aims to evaluate which splinting method offers the most favorable prognosis in cases of dental trauma involving horizontal intra-alveolar root fractures.

Search strategies were adapted for seven electronic databases and gray literature to identify studies evaluating the prognosis of horizontal intra-alveolar root fractures based on the type of splint used. The risk of bias in the included studies was assessed using the Joanna Briggs Institute Critical Appraisal tools. A Bayesian network meta-analysis was conducted.

A total of 3,174 references were retrieved, of which six studies met the inclusion criteria. No significant differences were found between the types of splints used and the healing outcomes of horizontally fractured intra-alveolar roots, including comparisons to cases without fixation. Across all studies, the degree of fragment displacement was a key factor influencing healing: the less displacement, the better the prognosis. Other treatment-related variables analyzed by the authors also played a role in determining tooth prognosis.

There may be no difference regarding the type of splint used when considering the healing of horizontal intra-alveolar root fractures; however, other factors may have influenced this outcome.

Understanding the fracture characteristics and the type of splinting intervention employed is essential for ensuring appropriate treatment in such cases.
