Horizontal root fracture followed for 6 years.

Intra-alveolar root fractures in permanent teeth are uncommon injuries among dental traumas. Generally, the principles of treating horizontal root fractures of permanent teeth are repositioning and fixation. The present paper reports 6-years follow up of two horizontally root-fractured teeth that were healed with calcified tissue. Both of the teeth were clinically and radiographically symptomless and showed complete pulp canal obliterations.
