The objective of the present report was to study the influence of the location (maxilla versus mandible) and class (Miller classification) of gingival recessions on the total root coverage achievement using the tunnel procedure with acellular dermal matrix in adjacent single-root teeth. Twenty-four patients with 93 recessions were treated and evaluated 1 year postsurgery. Results showed 100% of root covered in 67.9% of the maxillary recessions and 52.5% in the mandible (P = .676). In cases of partial root coverage, the initial recession diminished from 4.41 mm (SD: 1.12) to 0.82 mm (SD: 0.24) in the maxilla and from 3.78 mm (SD: 1.08) to 0.78 mm (SD: 0.30) in the mandible. Root coverage of 100% was observed in 74.07% of Miller Class I recessions in comparison with 43.59% of Class II recessions (P = .003).
