Abstract

Objectives: The present study aimed to evaluate the influence of various apical instrumentation sizes and tapers on the degree of debridement of the apical third of curved root canals. Methods: We used 60 extracted human mandibular first molars with mesial root curvatures of 20° to 30°. In all teeth, access cavity preparation was performed, followed by coronal flaring with Gates Glidden drills #1–4 (Dentsply Maillefer). Specimen teeth were subsequently randomly divided into five groups (n = 12). Each group was enlarged to a particular apical size and taper as follows: no apical preparation done (group I, Control group); 25/.04 and 25/.06 (Group II); 30/.04 and 30/.06 (group III); 35/.04 (group IV); 40/.04 (group V). Specimens were rinsed with 17% EDTA and 3% NaOCl solutions. We used a scanning electron microscope to evaluate specimens’ degree of debridement. Retrieved data were analyzed using Kruskal–Wallis and Mann–Whitney U-tests (p < 0.05). Results: Acceptable debridement was observed in groups III, IV, and V. Additionally, debridement was significantly better in Groups IV and V than in group II. Conclusion: Apical preparation with <30/.04 size results in an unacceptable degree of debridement of the apical third.

Abstract

Mandibular molar is usually two rooted with one mesial and one distal root. Additional roots are rare which requires accurate diagnosis and a methodical and scrupulous endodontic treatment. Objective: This paper aims to report the endodontic management of an unusual case of a mandibular permanent first molar with four roots (two mesial & two distal) and provide a clinical guideline to detect and manage these variant cases. Case report: A 15-year-old boy reported with a deep carious lesion in the lower left first molar (#36). The apical root contour of #36 on an intraoral periapical radiograph taken in different angulations suggested the presence of extra roots. A Spiral Computed Tomographic scan with multiplanar three-dimensional reconstructed images confirmed a fourrooted mandibular molar. Endodontic treatment of #36 was planned based on a diagnosis of pulpal necrosis with symptomatic apical periodontitis. The pulp chamber floor was assiduously explored along the developmental root fusion line (DRFL) to guide a trapezoidal access cavity and expose two mesial and two distal orifices. Conclusion: The present case report highlights the successful endodontic treatment of an atypical four rooted mandibular first molar by following a systematic approach from diagnosis to its clinical management.
