Inclusion criteria

Inclusion criteria: (1) participation in clinical studies „Root cover- age with bioabsorbable membranes and connective tissue grafts" (RATKA-KRÜGER 1999) and „Ten-Year Results After Connective Tissue Grafts and Guided Tissue Regeneration for Root Coverage“ (NICKLES 2010), (2) written inform consent

Exclusion criteria

Exclusion criteria: (1) Disease or condition (e.g. valvuar transplant) which cause transitory bacteremia (e.g. pocket probing depths or attachment loss) and make an antibiotic prophylaxis necessary
