Diagnosis and endodontic treatment in a mandibular first premolar with two canals: case report / Diagnóstico e tratamento endodôntico em primeiro pré-molar inferior com dois condutos radiculares: relato de caso

Objective: The objective of this article was to describe the diagnosis and the endodontic treatment of a mandibular first premolar with two root canals. Case report: A 67-year-old female patient presented to the dental clinic referring pain in the right mandibular first premolar. The patient reported induced pain and the sensation of "grown tooth". Clinical examination revealed a marked degree of dental abrasion associated with a slight swelling in the periapical region and positive percussion and cold tests. The radiographic examination revealed an apical radiolucency. A pulpal diagnosis of necrotic pulp and chronic perirradicular periodontitis were made. After access cavity, the canals were prepared using K-files, Gates-Glidden drills and 2.5% sodium hypochlorite. Gutta-percha cones and AH-Plus sealer were used during obturation with the lateral condensation technique. Conclusion: After a period of 23 months of follow-up, clinical and radiographic examinations revealed total regression of the lesion.

Objetivo: O objetivo deste artigo foi descrever o diagnóstico e tratamento endodôntico de um primeiro pré-molar inferior com dois canais radiculares. Relato de caso: Paciente de 67 anos de idade apresentou-se à clínica odontológica referindo dor no primeiro pré-molar inferior. A paciente relatava dor espontânea e sensação de "dente crescido". O exame clínico revelou um grau acentuado de abrasão dentária associada a ligeiro inchaço na região periapical e respostas positivas aos testes de percussão e frio. O exame radiográfico revelou a presença de uma radiolucência apical. Foi realizado o diagnóstico de polpa necrótica e periodontite perirradicular crônica. Após a realização da cavidade de acesso, os canais foram preparados utilizando limas tipo K, brocas Gates-Glidden e hipoclorito de sódio a 2,5%. Cones de guta-percha e cimento obturador AH-Plus foram utilizados na obturação com a técnica de condensação lateral. Conclusão: Após um período de 23 meses de acompanhamento, os exames clínicos e radiográficos revelaram regressão total da lesão.

Endodontic treatment of maxillary lateral incisors with anatomical variations

Maxillary lateral incisors usually exhibit a single root with a single canal. However, maxillary lateral incisor teeth with unusual morphology of root canal system are frequently reported. These cases of variable root canal anatomy can be treated well by nonsurgical endodontic methods. A detailed description of root canal morphology is fundamental for successful endodontic treatment. Treatment using an operating microscope, radiographs from different angles, and cone-beam computerized tomography (CBCT) can produce more predictable endodontic outcomes.

A maxillary canine with two separated root canals: a case report / 대한치과보존학회지

Maxillary canines have less anatomical diversities than other teeth. They usually have a single root and root canal. This report describes an endodontic treatment of a maxillary canine with two separated root canals which have not been reported through the demonstration of radiography and computerized tomography (CT). Even though appropriated endodontic treatment has been performed, the severe pain could happen due to lack of consideration of anatomical variations of the teeth. Therefore, the clinicians should be well aware of the possibility of anatomical variations in the root canal system during endodontic treatment even if the number of root canals is obvious such as in this case.
