MANDIBULAR PREMOLAR WITH TWO ROOTS AND TWO ROOT CANALS: A CASE REPORT.

For the success of a root canal treatment, an in-depth knowledge of pulpal anatomy and its variations are essential. Failure to perform thorough debridement and improper obturation will lead to reinfection of the root canal, which will adversely affect the treatment outcome. Mandibular premolars usually have single root with single root canal system. Howeveranatomic variations of mandibular premolar have been reported. The clinician should be aware of the configuration of the pulp system for the successful endodontic treatment. The incidence of two roots in these teeth is quite rare. This report presents the clinical management of mandibular premolar having two roots bifurcated at the mid-root level

Non Surgical Management Of Intra Oral Sinus In Mandibular Canine With Two Canals And Mandibular First Premolar With Two Roots: A Case Report

The root canal morphology of teeth is more often highly complex and variable. Therefore, any attempt to perform successful endodontic treatment must be preceded with thorough and detailed knowledge of the root canal morphology and its possible variations.1 The majority of mandibular canines are single rooted with one root canal. The possibility of having two canals in mandibular canines is reported to be infrequent.2,3 Mandibular first premolars have also been typically described in literature as single–rooted with incidence of extra roots to be rarely present.4 This paper describes a case report on non surgical management of intra oral sinus with presence of two root canals in mandibular canine (Vertucci Type II) and two rooted mandibular first premolar (Vertucci Type IV) in same patient, which is a rare entity.

A variation anatomy of mandibular canine with successful endodontic management.

Knowledge of development of the teeth and their natural anatomy is applicable to clinical practice, especially during root canal therapy. Although endodontic treatment of mandibular canine generally offers no difficulties, it is advisable to always be aware of the possibility of variations in its internal anatomy. Mandibular canines are recognized as usually monoradicular i.e., single rooted, in most of the cases although approximately 15% may have two canals. Further the incidences of two rooted canine with two root canals is as low as 1.7%. This article presents a case of mandibular canine having two roots with two canals and its successful endodontic management.

Canino mandibular con dos raíces / Mandibular canine with two roots

El canino inferior es un diente con raíz larga y ancha que le permite una adecuada implantación en el arco dentario. Es considerado un pilar valioso en muchos tratamientos rehabilitadores. Con la finalidad de mantener este elemento dentario es necesario realizar un correcto diagnóstico, para lo que se tendrá en cuenta el conocimiento de las variaciones anatómicas. El objetivo del artículo es presentar un caso de canino mandibular con dos raíces con sus respectivos canales radiculares .Paciente femenina de 21 años, que acudió a la Clínica de Radiología de la Facultad de Odontología de Piracicaba con indicación de una radiografía panorámica para valorar cirugía de terceros molares. Llamó la atención una configuración inusual de las raíces de los caninos mandibulares. En el examen de tomografía computarizada de haz cónico se observó que el canino mandibular del lado derecho presentaba dos raíces separadas, cada una con sus respectivos canales radiculares. Se concluyó que a pesar de la baja prevalencia de las variaciones anatómicas, estas pueden ocurrir en el número de raíces y canales de los caninos mandibulares, tal como se presenta en este reporte de caso(AU)

The mandibular canine is a robust and long tooth which allows an adequate implantation in the dental arch. It is considered a valuable pillar in many rehabilitating treatments. In order to maintain this important dental element, it is necessary to make a correct diagnosis, for which the knowledge of the different anatomic variations should be kept in mind. The objective of this article is to present a case of a mandibular canine with two roots with their respective root canals. A 21-year-old female patient went to the Radiology Clinic at the Faculty of Odontology of Piracicaba with the indication of a panoramic radiography for preoperative third molars surgery. An unusual root configuration of the mandibular canines was observed. In the cone beam CT, it was observed that the right mandibular canine presented two separate roots, each one with their respective radicular canals. It was concluded that, despite of the low prevalence of anatomical variations, these can occur in the root system of the mandibular canines, as presented in this case report(AU)

An Endodontic Mishap In Maxillary Lateral Incisor With Two Roots : A Case Report.

A 24 year old male was referred with pain and swelling in relation to a previously root canal treated maxillary left lateral incisor. Radiographic examination revealed presence of a second root which was left untreated in the previous treatment. This endodontic mishap had led to the failure of the case. During the retreatment the second canal was detected and cleaned, however considering the amount of bone loss around the second root, it was resected. This case report demonstrates the need for greater attention in treating the root canal of maxillary lateral incisors due to its anomalies, and also the need for thorough evaluation of good quality preoperative radiograph to avoid such mishaps.

Two-Rooted Mandibular First Premolar : Case Report.

Abnormalities in the root canal anatomy are a commonly occurring phenomenon. A thorough knowledge of the root canal anatomy and its variations is necessary for successful completion of the endodontic treatment. Mandibular second premolars usually have a single root and a single root canal. The incidence of two separate roots itself in this tooth is quite rare. Mandibular premolars are known for having an aberrant anatomy. Often considered an enigma to the endodontist, the mandibular first premolar with dual canals dividing at various levels of the root can generate complex mechanical problems.Reports about the incidence of extra roots in these teeth are quite rare. This paper attempts at explaining a rare case of successful endodontic management of a two-rooted mandibular second premolar with awareness of data pertaining to the number of canals, knowledge of canal morphology, correct radiographic interpretation, and tactile examination of canal walls which are important in detecting the presence of multiple canals.
