Decision tree for the treatment of Miller’s [1] recession-type defects by Chambrone and Tatakis [2] (the thicker the “branch,” the stronger the base of evidence). It is expected that there is wound healing consisting of long junctional epithelium and connective tissue attachment (with fibers parallel to the root surface), but some degree of tissue regeneration may occur (mainly for EMD and GTR-based procedures). Since the majority of the publications included in the study evaluated single tooth recession sites, the decision tree seems better designed for determining appropriate treatment for single tooth sites, but it may guide the treatment of multiple recession-type defects as well. The use of root modification agents does not promote positive or negative clinical modifications.
