Split mouth design with 26 sites treated with Puros Dermis and 26 sites treated with Alloderm. A coronally advanced flap was used.
At 6 months both groups had similar improvements in recession coverage with an average of 2.83 mm for Puros Dermis and 3.13 mm for Alloderm. 81.4% root coverage for Puros and 83.4% for Alloderm. Difference between the two materials was not statistically significant.
No statistical or clinical difference in root coverage, probing depth or keratinized tissue in coronally advanced flaps using etither of the two acellular dermal matrix materials. Both were successful in achieving root coverage.
