Effects of enamel matrix derivative and basic fibroblast growth factor with μ-tricalcium phosphate on periodontal regeneration in one-wall intrabony defects: an experimental study in dogs.

: This study evaluated the effects of enamel matrix derivative (EMD) and basic fibroblast growth factor (bFGF) with μ-tricalcium phosphate (μ-TCP) on periodontal healing in intrabony defects in dogs. One-wall intrabony defects created in dogs were treated with μ-TCP alone (μ-TCP), EMD with μ-TCP (EMD/μ-TCP), bFGF with μ-TCP (bFGF/μ-TCP), and a combination of each (EMD/bFGF/μ-TCP). The amount of new bone formation was not significant for any group. The EMD/bFGF/μ-TCP group induced significantly greater new cementum formation than the μ-TCP and bFGF/μ-TCP groups and, although not significantly, formed more new cementum than the EMD/μ-TCP group. These findings indicate that EMD/bFGF/μ-TCP treatment is effective for cementum regeneration.
