Correlation between the CPITN score and anaerobic periondontal infections assessed by BANA assay / Correlação entre o índice CPITN e infecções anaeróbicas periondontais avaliada pelo teste BANAS

In the present investigation the ability of subgingival plaque to hydrolyse BANA (Perioscan) was correlated with CPITN scores. Among 281 sites investigated, 136 had a CPITN equal to 2 with a highly significant positive BANA value (107 sites). A CPITN equal to 3 was also siginificantly BANA positive (90 sites). These findings clearly demonstrate the relationship between CPITN and anaerobic microorganisms (BANA positive)
