Endodontic management of mandibular second premolar with type IX canal configuration using cone-beam computed tomography as a diagnostic aid: A rare case report

Abstract

Successful endodontic treatment requires knowledge of the root canal anatomy, cleaning, and shaping followed by three-dimensional filling of the root canals. With the advent of newer diagnostic aids such as cone-beam computed tomography (CBCT) and magnifying tools such as dental operating microscope and loupes, it has become easier for an operator to identify the root canal anatomy of teeth and reduce the risk of procedural accidents and failures. Variations in root canal configuration require modification in access cavity preparation, disinfection, and obturation of the canals. Mandibular premolars are identified to have unusual root and canal anatomy which increases the risk of endodontic failure when additional canals remain undiagnosed. The present case report elaborates successful endodontic management of a mandibular second premolar with Type IX root canal configuration using CBCT as a diagnostic tool.

Cone-beam and micro-computed tomography for the assessment of root canal morphology: a systematic review

“…Similarly, cone beam computed tomography (CBCT) is frequently used for the identification of root canal morphology. 8,9,12,13 CBCT overcomes some of the disadvantages of µCT such as scan time, radiation dosage and high cost, as well as widespread use in clinical practice, therefore, it has also been used in laboratory assays.…”

Comparative Analysis of Treatment Outcomes and Patient Experiences: Single-Visit versus Multiple-Visit Root Canal Treatment

“…This finding suggests that the anatomy and complexity of the root canal system may influence treatment outcomes (15,16). Premolars often have simpler canal configurations, making them more amenable to effective cleaning and obturation, which could contribute to the higher success rates observed in this tooth type (17,18). In contrast, molars may present more complex canal systems, posing challenges in achieving thorough disinfection and obturation, thus potentially impacting treatment success rates (19).…”

A tomografia computadorizada de feixe cônico como exame complementar na Endodontia: relato de caso

“…O tratamento dos canais radiculares é um procedimento odontológico comum para preservar os dentes, tratando doenças da polpa dentária e região perirradicular 6 . A terapia endodôntica consiste principalmente na limpeza quimico-mecânica do sistema de canais radiculares, de modo a remover todos os detritos de tecido mole do interior do dente e sua completa obturação tridimensional com um material inerte [7][8][9][10][11] .…”
