Effect of splinting times on the healing of intra-alveolar root fractures in 512 permanent teeth in humans: A Scandinavian multicenter study.

While the results suggest that long-term splinting favors hard tissue deposition, one cannot, however, conclude that long-term splinting definitely favors hard tissue healing since the treatment protocols were not randomized among the three centers. More clinical studies on the role of splinting time need to be done.
