Mineral Trioxide Aggregate for Intruded Teeth with Incomplete Apex Formation.

The axial displacement of a tooth within the alveolar bone is called traumatic intrusive luxation. The treatment of immature permanent teeth with incomplete root formation is a challenging procedure, as the prognosis is uncertain. The objective of the present article is to report the successful treatment of traumatic intrusive luxation in teeth with incomplete root formation, where mineral trioxide aggregate (MTA) was used as an apical plug to induce apexification. A 10-year-old boy was referred to our department for emergency treatment of dentoalveolar trauma to the maxillary central incisors. After clinical and radiographic examination, the teeth were surgically repositioned and rigidly fixed. Three months later, a pulp vitality test of both teeth elicited a negative response. Endodontic therapy with an MTA plug was used to induce apexification as root formation was incomplete. The root canals were then filled. Clinical and radiographic examination was then performed again at 2 and 4 months later. The MTA apical plug was effective in inducing apexification and maintaining both teeth.

Endodontic Treatment of Hypertaurodontic Mandibular Molar Using Reciprocating Single-file System: A Case Report.

Taurodontism is a developmental tooth disorder characterized by lack of constriction in the cementoenamel junction and consequent vertical stretch of the pulp chamber, accompanied by apical displacement of the pulpal floor. The endodontic treatment of teeth with this type of morpho-anatomical anomaly is challenging. The purpose of this article is to report the successful endodontic treatment of a hypertaurodontic mandibular molar using a reciprocating single-file system.
