Pulpotomy Subsequent to Occlusal Reduction for Prosthesis: Two Case Reports
Objectives: Pulpotomy consists to remove a part of dental pulp in order to a vital pulp therapy. Usually, root canal treatment is performed following excessive occlusal reduction of a tooth for adequate room to restore an edentulous space. These two case reports aimed to examine pulpotomized teeth for the placement of removable partial dentures.
Methods: Two patients aged 36 and 58 years were referred to us for root canal treatment prior to crown height reduction (respectively ≠16, ≠17, ≠25 and ≠47). Pulpotomies were carried out in agreement with the practitioner and the patients. The procedure included local anesthesia, occlusal reduction, full pulpotomy according to the standard protocol, and sealing of the pulp chamber with tricalcium silicate-based material ( Biodentine™, Septodont, Saint Maur des Fosses, France). At 1 week postoperatively, 3-4 mm deep cavity was prepared with a sufficient Biodentine™ base for the coronal restoration using composite resin (G-ænial® posterior, GC, Tokyo, Japan). The removable partial dentures were placed at another appointment, then clinical and radiographic examinations of pulpotomized teeth were done for up 2 years.
Results: No sensitivity or postoperative pain was reported one week after the procedure. At two years postoperatively, all patients claimed excellent chewing ability with their pulpotomized teeth. The periodontal pain tests were negative, retroalveolar radiographic observations showed normal periodontium, the absence of periapical lesion and root resorption. The teeth were functional and asymptomatic.
Conclusions: Preserving the radicular pulp seems to maintain the proprioceptive and damping abilities of the tooth. So, pulpotomy could be a reliable alternative for the treatment of the teeth whose pulpectomy was indicated in excessive occlusal reduction. Further clinical studies using randomized controlled trials would support this approach.
