KNOWING THE ABERRATIONS TO AVOID THE SETBACKS - A RARE CASE REPORT ON FOUR ROOTED MANDIBULAR PERMANENT FIRST MOLAR
2019
Aim: The aim of this case report is to present a rare case of a mandibular first molar with four completely separated roots and its successful non- surgical endodontic management. It also emphasizes on the role of radiographs in effectively managing such
cases.
Background: The successful outcome of a root canal treatment invariably depends on
proper identification of the canals, adequate biomechanical preparation and obturation.
Though the presence of an extra canal in the mandibular molars has often been reported in literature, but the incidence of four completely separated roots is extremely rare.
Case discussion: A 9-year-old male patient visited our department with chief
complaint of pain in the lower right back tooth. Intra oral examination showed advanced
Class I cavity with exposed pulp in the lower right first mandibular molar with tenderness
on vertical percussion with no associated swelling, sinus or fistulous tract. Radiographic
examination revealed an interesting finding, that is, the outline of 2 periodontal ligament
spaces in both mesial and distal roots with the presence of four separate roots of similar
length. Non-surgical endodontic treatment followed by placement of a stainless steel crown
was planned for the tooth. Confirmation of the canals length and obturation was done using
cone beam computed tomography (CBCT).
Conclusion: A thorough knowledge of the intricacies of the root canal morphology is
important to the clinician for a successful treatment outcome. These aberrations in root
morphology though uncommon do exist and can be missed if thorough radiographic
evaluations are not instigated at the initial stages
Clinical significance: This case report will tend to reinforce awareness in clinicians
on capricious root canal morphology in permanent mandibular first molar.
