Background: Bleeding on probing (BOP) is an indicator of tissue inflammatory response to bacterial pathogens. Because anatomical limitations the entity and physical state of microbial aggregations located under the gingival margin and their relations to BOP have been hardly investigated till now. The recent introduction of the endoscopy has allowed clinicians to view the subgingival environment in a non-traumatic way. Aim of this study is to evaluate the correlation between BOP and subgingival deposits by using this new technology. Methods: At one-month revaluation of 16 periodontal patients treated with scaling and root planning, 107 teeth (642 individual sites) were evaluated for plaque index (PI), gingival index (GI), probing pocket depth (PPD), bleeding on probing (BOP), endoscopic biofilm index (EBI) and endoscopic calculus index (ECI). Results: A linear association between BOP and PD, EBI, and ECI was detected. The BOP provided a high level of specificity but quite low sensitivity values both for ECI (sensitivity 40%, specificity 86%) and EBI (sensitivity 37%, specificity 89%). The BOP sensitivity was directly linked to the amount of subgingival deposits. Conclusions: This study demonstrates a direct relationship between BOP and presence/amount of subgingival deposits. More investigations on larger samples are however needed.

Abstract

Background: Bleeding on probing (BOP) is an indicator of tissue inflammatory response to bacterial pathogens. Because anatomical limitations the entity and physical state of microbial aggregations located under the gingival margin and their relations to BOP have been hardly investigated till now. The recent introduction of the endoscopy has allowed clinicians to view the subgingival environment in a non-traumatic way. Aim of this study is to evaluate the correlation between BOP and subgingival deposits by using this new technology. Methods: At one-month revaluation of 16 periodontal patients treated with scaling and root planning, 107 teeth (642 individual sites) were evaluated for plaque index (PI), gingival index (GI), probing pocket depth (PPD), bleeding on probing (BOP), endoscopic biofilm index (EBI) and endoscopic calculus index (ECI). Results: A linear association between BOP and PD, EBI, and ECI was detected. The BOP provided a high level of specificity but quite low sensitivity values both for ECI (sensitivity 40%, specificity 86%) and EBI (sensitivity 37%, specificity 89%). The BOP sensitivity was directly linked to the amount of subgingival deposits. Conclusions: This study demonstrates a direct relationship between BOP and presence/amount of subgingival deposits. More investigations on larger samples are however needed.
