Aim: A thorough understanding of root and canal anatomical variations is essential for achieving successful endodontic treatment. Literature continues to demonstrate complex root and canal anatomical variations in mandibular third molars which are sometimes in close approximation to the inferior alveolar canal. Methodology: A 26-year-old male patient was referred for endodontic treatment of a three-rooted mandibular third molar with a dilacerated distal root and close approximation to the inferior alveolar canal. A cone beam computed tomography was performed to assess the root and canal anatomical variations together with the inferior alveolar canal. Conventional endodontic treatment was performed using a rotary nickel-titanium file system, and the canals were then obturated using a cold lateral condensation technique. Results: The endodontic treatment procedures were performed successfully and in the follow-up visit, the tooth was asymptomatic. Conclusions: Despite limited accessibility and challenges during root canal treatment procedures, retaining every functional component of the dental arch, including mandibular third molars, is an essential goal of contemporary dental practice.
This study aimed to compare the shaping ability of ProTaper Gold (PTG) and the newly developed ProTaper Ultimate (PTU) systems in artificial S-shaped canals. Both files are manufactured via gold thermal treatment methods and have variable taper along their working part. Thirty-Two S-shaped canals in clear resin blocks were prepared up to an apical size of 25 using PTU and PTG instruments (n = 16 canals/group). Resin blocks were filled with ink and photographed before & after instrumentation to develop composite images by superimposition. The amount of removed resin was measured perpendicularly to the canal surface in 18 points, in addition to the canal transportation and centering ratio. Statistical analysis was performed by using Manne-Whitney U-test (α = 0.05). No broken files or aberrations were recorded during instrumentation. PTG significantly removed a higher amount of resin at 4, 6, 8, and 9 mm from the apex, but at 1 mm PTU significantly cut a higher amount (p < 0.05). Concerning transportation & centering ability, both files deviated from the center and at 3 mm PTU yielded significantly higher deviation, while at 4 mm PTG recorded a higher value (p < 0.05). In conclusion, PTU produced more conservative preparation than PTG especially in the coronal third, while for maintaining the original canal curve, PTG caused lesser deviation at the beginning of the apical curvature.
Aim: This report aims to present the application of partial pulpotomy procedures in fractured maxillary central incisors with immature roots. The application of this treatment approach in fractured immature permanent teeth is advantageous but a number of challenges exist particularly when the affected teeth are severed with complicated fractures Methodology: Two cases of complicated crown fractures are reported. A 7-year-old male patient with broken maxillary left central incisor tooth and 8-year-old female patient with fractured maxillary right and left central incisor teeth were referred to the clinic after trauma. Partial pulpotomies were performed and MTA was applied directly onto the pulps. Results: Hard tissue barrier was observed after treatments. Conclusions: Partial pulpotomy is a valid treatment approach in which part of an exposed vital pulp is removed while preserving the vitality and function of the remaining part.
