Volumetric analysis of intrabony defects in aggressive periodontitis patients following use of a novel composite alloplast: a pilot study.

Objectives: Hydroxyapatite, tricalcium phosphate, and bioactive glass are the most commonly studied alloplastic materials in periodontal regeneration. These materials have been tested alone and in combination with one another, but evaluation using all three materials in one defect has not yet been attempted. Although posttreatment histologic evaluation or reentry procedures are ideal for objectively assessing regeneration, computed tomography (CT) has become one more technique in clinicians' armories to judge the effectiveness of any such interventions.
