Efficacy of Micronized Acellular Dermal Graft for Use in Interproximal Papillae Regeneration

The aim of this study was to evaluate interdental papillary reconstruction based on a micronized acellular dermal matrix allograft technique. Thirty-eight papillae in 12 patients with esthetic complaints of insuffi cient papillae were evaluated. Decreased gingival recession values were found postoperatively (P .001). Chi-square analysis showed signifi cantly higher postoperative Papilla Index values (chi-square = 43, P .001), further supported by positive symmetry statistical analysis values (positive kappa and weighted kappa values). This procedure shows promise as a method for papillary reconstruction.
