Mineral Trioxide Aggregate (MTA) has been advocated over the last years with excellent results as a valuable material in the treatment of root canal perforations, in apexification of immature teeth, as in root-end filling following apicoectomies (Pitt Ford, Friedman, Grossman etc.). In cell cultures, MTA has displayed favorable responses, that ranged from behavior very similar to that to titanium surfaces, to obvious stimulation (Pistorius, Willershausen, Marroquin etc.). However, the role of MTA in treating root fractures has been so far less investigated.

Case report

A 43 yo female patient who suffered a home accident was referred. The accident resulted in the incomplete alveolar fracture of region 23-25, luxation towards labial and labial displacement of 23. Primary trauma care missed the dental diagnosis and delayed with 48 hrs the report of the patient to the dentist, that referred her immediately to the endodontist. On examination, tooth 23 labially out of alignment, severe pain at slightest touch and slight oedema were noticed. Standardized radiographs revealed a very thin, artifact-like horizontal fracture of the mid third root of 23. Treatment options, varying from avulsion to transfixation of 23 were taken into consideration. The patient complied with the endodontist' suggestion to extreme conservative treatment approach. Afer having obtained an informed consent from the patient, the incomplete alveolar fracture was reduced under anesthesia, and the root canal treated with Ni-Ti rotary instruments (ProTaper® - Dentsply-Maillefer, Ballaigues, Switzerland). Mineral Trioxide Aggregate (ProRoot®; DENTSPLY/Tulsa Dental, Tulsa, Oklahoma, USA) was placed into the canal as a permanent filling. Postoperative radiographs were taken. 23 was splinted in correct position by mean of an acrylic provisional bridge. Postterapeutic care included chlorhexidine 0,2% rinses. Precautions were taken to eliminate occlusal interferences that might cause further trauma to 23. Following the treatment, the patient did not display any sign of posttraumatic symptomatology.

At 4 months, tooth 23 remained asymptomatic. After removal of the provisional bridge, 23 displayed no mobility. Radiographic examination reveals a blurry profile of the fracture site, with very slight periradicular modifications. Splinting by provisional bridge is scheduled to remain in place until 6 months after the endodontic treatment.

Discussion and Conclusions

The case report suggests that:
1) deep horizontal root fracture combined with teeth displacement can be successfully treated;
2) MTA can serve as the best choice for a definitive root filling material in horizontal fractures, when root canal treatment is adequately provided;
3) the immediate intervention of the practitioner with the rationale application of the sequence re-placement-rotary root canal treatment-Root-MTA-splinting spectacularly improves the conservative outcome of similar cases.
