A review of root resective therapy as a treatment option for maxillary molars.

Restorative treatment planning is often confounded when periodontal attachment loss, caries or tooth fracture involves the furcation area of the tri-rooted maxillary molars. Although such involvement invariably diminishes the long-term prognosis of the affected teeth, extraction is not always an option. Root resective therapy, which removes the involved root plus its associated crown portion (trisection), is one of several treatment modalities that can be used in such cases. This article reviews the indications and contraindications for root resective therapy, describes the techniques of surgical trisection and presents a case in which combined resective, endodontic and prosthetic management resulted in a successful outcome.
