ABSTRACT
Internal root resorption (IRR) is a rare pulp disease. Its etiology involves late pulpal inflammations and trauma, among others. IRR may also show some symptoms, and is usually detected by X-rays. However, its diagnosis is significantly improved by the use of cone beam computed tomography (CBCT). The objective of this case report was to account for the diagnosis and management of an internal root resorption without perforation. The patient, a 26-year-old male, went to the School of Dentistry at Universidad Andres Bello, Concepción, without having symptoms in the tooth 1.1. Anamnesis revealed the presence of previous symptoms. CBCT examination showed absence of bowl-shaped calcified dentin tissue on the inner walls of the root canal with apical lesion but without perforation of surrounding tissues. Endodontic treatment was performed using the following methods: irrigation of the root canal with 2 percent chlorhexidine (CHX) using a Max-i-probe cannula and simultaneous cavitation of the irrigant Then calcium hydroxide (CH) was applied as intracanal medication for a week and Schilders technique for vertical compaction was used. The patient was checked after one week and then after six months. He did not have any symptoms. Early diagnosis using modern imaging equipment, appropriate use of ultrasound for chemomechanical debridement and thermoplastic filling techniques contribute to a more favorable prognosis of patients with internal root resorption...
La reabsorción radicular interna (RRI) es una condición pulpar poco común, cuyo origen etiológico incluye procesos inflamatorios tardíos de la pulpa, traumatismos, entre otros; por otra parte ésta podría presentar sintomatología. Generalmente es detectada por hallazgo radiográfico, sin embargo, requiere de un mejor método de diagnóstico por imagen como es la tomografía computarizada cone beam (TCCB). El objetivo de este reporte de caso fue detallar el diagnóstico y manejo de una reabsorción radicular interna sin perforación. El paciente de sexo masculino, 26 años de edad acudió a la Facultad de Odontología de la Universidad Andrés Bello sede Concepción, sin presentar síntomas en el diente 1.1. La anamnesis refirió presencia de sintomatología con anterioridad. La evaluación mediante la TCCB demostró ausencia de tejido dentinario calcificado en forma de cuenco en las paredes internas del conducto radicular con presencia de lesión apical sin evidenciar perforación hacia tejidos circundantes. Se realizó el tratamiento endodóntico, usando los siguientes métodos: el conducto radicular se irrigó con Clorhexidina (CHX) al 2 por ciento usando cánula Max-i-probe y simultáneamente fue realizada la cavitación del irrigante, luego se colocó Hidróxido de Calcio (HC) como medicación intraconducto por una semana. Se usó la técnica de compactación vertical de Schilder más un control del paciente a la semana y a los 6 meses. El paciente no presentó sintomatología. El diagnóstico temprano mediante herramientas imaginológicas contemporáneas, la utilización del ultrasonido para el desbridamiento químico-mecánico y las técnicas de obturación termoplásticas usadas acorde al caso hacen que las piezas con reabsorción radicular interna tengan un pronóstico más favorable...

Objectives: To report a clinical case of endodontic treatment of a C-shaped mandibular second molar. Casereport: A patient came to the dental clinic of the Paulista University complaining of pain in tooth 47. Thediagnosis was irreversible pulpitis in which biopulpectomy was recommended. Access was made, and afteridentifying the distal and mesiobuccal canals, the absence of the mesiolingual canal was observed and withthe aid of a surgical operating microscope it was possible to confirm the presence of C-shaped canal. Rotaryinstrumentation with Profile type NiTi files was initiated making a stop up to file #40.04 in the distal canaland up to file #35.04 in the mesial canal. The filling technique performed was thermal compaction usingMcSpadden condenser #45. Conclusion: The case has been followed-up for nine months and the patientdoes not present painful symptomatology, thus indicating the clinical success of the case.
Objetivos: Relatar um caso clínico de tratamento endodôntico de segundo molar inferior em formato de C. Relato de caso: Um paciente chegou à clínica odontológica da Universidade Paulista com queixa de dor no dente 47. O diagnóstico foi pulpite irreversível, sendo recomendada a biopulpectomia. O acesso foi realizado e, após identificação dos canais disto e mésio-vestibular e verificação da ausência do canal mésio-lingual, com auxílio de um microscópio cirúrgico foi possível confirmar a presença de um canal em forma de C. Foi iniciada instrumentação rotatória com limas tipo NiTi Profile, com parada na lima #40.04 no canal distal e lima #35.04 no canal mesial. A técnica de obturação realizada foi a de compactação térmica utilizando condensador deMcSpadden #45. Conclusão: O caso foi acompanhado durante nove meses, sendo que o paciente não apresentou sintomatologia dolorosa, confirmando, portanto, o sucesso clínico do tratamento.
