Individuals were divided in to two groups: 96 regular compliers (RC<\/jats:styled-content>) and 116 irregular compliers (IC<\/jats:styled-content>). Full\u2010mouth periodontal examination was performed. Social, demographic, behavioral and biological variables of interest were collected at all PMT<\/jats:styled-content> visits.
