Five-year results of SCTG and ADMA were similar in terms of CRC and reduction of RD and RW. Both techniques showed a significant relapse associated with returning to horizontal toothbrushing habit. Increase of GW was stable in SCTG-treated sites, but reached to pre-surgical values in ADMA-treated cases.

These results provide additional evidence that class II HLA polymorphisms, particularly in the DQ locus, are associated with protection against and susceptibility to aggressive periodontitis.
