Healing of horizontal root fractures

Conservative treatment of a cervical horizontal root fracture and a complicated crown fracture: a case report

Abstract This case report describes successful long-term conservative management of a cervical root fracture and a complicated crown fracture of the maxillary central incisors in a 12-year-old patient. A mineral trioxide aggregate partial pulpotomy was performed on the maxillary right central incisor, while the maxillary left central incisor was splinted to the neighbouring lateral incisor using an acid-etch technique. Both teeth remained asymptomatic throughout the 3.5 years of a review period, with the cervical root fracture having mostly healed with the formation of a calcified tissue between the fragments. Two different treatment methods were used for two different injuries that resulted in pulp preservation in both cases. This in turn has provided for normal root development to occur while also allowing for preservation of bone.

Spontaneously healed horizontal root fracture in maxillary first premolar: report of a case

Root fractures of the posterior teeth are rare and occur as a result of severe trauma. This study describes the horizontal root fracture of a maxillary first premolar. The fractured roots were discovered during a routine radiographic examination. The tooth was asymptomatic and responded positively to electric pulp testing. The patient reported accidental trauma, which occurred 14 years before. Our case is an example of spontaneously healed fractured roots. The interesting findings were that the healing was observed even in the presence of two roots, including preservation of the vitality of the pulp.

Horizontal root fractures: a case report

This case report describes the treatment of an upper right central incisor with an intra-alveolar horizontal root fracture at the level of the middle third and an upper left central incisor with the horizontal root fracture in the cervical third. The root fractures were reduced and rigidly splinted for 4 months. The endodontic therapy was instituted in the upper left central incisor because there was no possibility of fracture repair due to the proximity of the fracture and the gingival sulcus. As soon as the diagnosis of pulp necrosis was established in the upper left lateral incisor, the endodontic treatment was performed. After 3 years and 9 months check-up appointments showed healing in the middle root third of the upper right central incisor and it responded within normal limits to pulp testing. Thus, there is no need for endodontic therapy on this tooth.

Repair of untreated horizontal root fractures: two case reports

Intra-alveolar root fractures of incisor teeth are more frequent than other dental injuries. These case reports describe two untreated horizontal root fractures of the maxillary right central incisors. Patients reported accidental trauma, which occurred several years ago. These fractures were discovered during a routine full-mouth radiographic survey. Teeth were asymptomatic and tested vital to electric pulp tests.

Treatment of a horizontal root fracture by vital root submergence

Cervical third horizontal root fractures in immature permanent teeth often present complicated and unpredictable treatment options. This case report describes the successful management of a horizontal root fracture in an open apex tooth by vital root submergence and subsequent nonsurgical root canal therapy.
