Résumé
O tratamento de dentes jovens traumatizados requer atenção especial devido à presença de ápice aberto e paredes dentinárias finas, inviabilizando um tratamento endodôntico convencional. Para tanto, é necessária a realização de um procedimento para induzir a formação de uma barreira mineralizada com o auxílio de materiais biocompatíveis, como o hidróxido de cálcio e o agregado trióxido mineral (MTA). O objetivo deste trabalho é relatar um caso clínico no qual se optou por realizar a apicificação com hidróxido de cálcio, durante dez meses, e após confirmação da existência de uma barreira, realizou-se a obturação com plug apical de MTA e guta percha. A apicificação é uma técnica que apresenta alto índice de sucesso, sendo assim consagrada para o processo de rizogênese incompleta.
The treatment of traumatized young teeth requires special attention due to the presence of open apex and thin dentine walls, preventing conventional endodontic treatment. Therefore, it is necessary perform a procedure to induce formation of mineralized barrier with the aid of a biocompatible materials such as calcium hydroxide and mineral trioxide aggregate (MTA). The aim of this study is report a case wich it was decided to perform apexification with calcium hydroxide for ten months, and after confirmation of the existence a barrier, held filling with apical plug of MTA and gutta percha. The apexification is a technique of high success rate, so devoted to the process of incomplete root formation.

The dental gemination is a morphological alteration that can occur during the development of the dental germ, resulting in a total or partial formation of two teeth which are not completely separate. The aim of this work was to relate an unusual case of gemination by the periapical radiography of superior central incisive in the permanent dentition.
La geminación dental es una alteración morfológica que puede suceder durante el desarrollo dental del embrión, dando por resultado la formación parcial o total de dos dientes que no estén separados totalmente. El objetivo de este trabajo fue describir un caso infrecuente de geminación, a través de la radiografía periapical en incisivos centrales superiores en la dentición permanente.

Odontodysplasia is a relatively uncommon condition that can affect both primary and permanent dentition. It is characterized by defective formation of both enamel and dentin, with enlarged pulp chambers and root canals with open apices. It is usually a localised condition where one or few teeth may be involved. Sometimes, an entire quadrant or more than one quadrant may be involved but generalized involvement is extremely rare. An interesting case of a generalized odontodysplasia affecting both primary and permanent dentition in an eight year old girl is presented here.

An eleven year old girl reported to J. S. S. Dental College with spontaneous pain in the left mandibular region. On examination, left mandibular second premolar was found to be hypoplastic and grossly destroyed. On radiographic evaluation, an uncommon variation of bifurcation at the apical one third of the root was seen while the contralateral tooth was normal. Treatment planning included extraction of the tooth and evaluation of the morphodifferentiation which showed a webbed appearance in the bifurcated root contrary to the radiographic finding. This webbed appearance could be due to hypomineralisation due to trauma to the developing roots from the infection of its predecessors.
