An in vivo clinical study was performed to evaluate the healing of a new approach to the repair of incomplete vertical root fractures. The two-stage surgical procedure incorporated ultrasonic fracture cleaning, bonding of the fracture repair with silver glass-ionomer cement, placement of a bone graft material, and application of guided-tissue regeneration. Of the six roots in the study, five failed within 2 to 11 months. One root continued to be symptom-free, without periodontal pocket formation for 1 yr, but then failed because of extension of the incomplete root fracture to the lingual of the root.

D014092	Tooth Root	The part of a tooth from the neck to the apex, embedded in the alveolar process and covered with cementum. A root may be single or divided into several branches, usually identified by their relative position, e.g., lingual root or buccal root. Single-rooted teeth include mandibular first and second premolars and the maxillary second premolar teeth. The maxillary first premolar has two roots in most cases. Maxillary molars have three roots.

D016557	Guided Tissue Regeneration, Periodontal	Techniques for enhancing and directing cell growth to repopulate specific parts of the PERIODONTIUM that have been damaged by PERIODONTAL DISEASES; TOOTH DISEASES; or TRAUMA, or to correct TOOTH ABNORMALITIES. Repopulation and repair is achieved by guiding the progenitor cells to reproduce in the desired location by blocking contact with surrounding tissue by use of membranes composed of synthetic or natural material that may include growth inducing factors as well.

D016722	Cermet Cements	Fluoride-releasing restorative materials made by the sintering of metal (usually silver) particles to glass ionomer powder. Glass ionomers are fluoride-releasing cements that are not very durable. Sintering of the metal particles is a means of improving those physical properties that will make the glass ionomer cement more durable.	Cermet,Ketac-Silver,Cements, Cermet,Ketac Silver,KetacSilver
