Due to 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 observe the subgingival environment in a non-traumatic way. The aim of this study is to evaluate the correlation between BOP and subgingival deposits by using this new technology. Methods: 107 teeth (642 individual sites) from 16 periodontal patients, treated with scaling and root planing, 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) at one-month revaluation. 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. 7 28 2009 154 160 TODENTJ-3-154 1 10.2174/crossmark_policy opendentistryjournal.com benthamopen.com true Peer Reviewed Single blind Checked with iThenticate 2009-2-23 2009-4-2 2009-5-8 2009-7-28 http://creativecommons.org/licenses/by-nc/3.0/ 10.2174/1874210600903010154 1553505078 https://opendentistryjournal.com/VOLUME/3/PAGE/154/ https://opendentistryjournal.com/contents/volumes/V3/TODENTJ-3-154/TODENTJ-3-154.pdf https://opendentistryjournal.com/contents/volumes/V3/TODENTJ-3-154/TODENTJ-3-154.pdf https://opendentistryjournal.com/contents/volumes/V3/TODENTJ-3-154/TODENTJ-3-154.pdf https://opendentistryjournal.com/contents/volumes/V3/TODENTJ-3-154/TODENTJ-3-154.pdf https://opendentistryjournal.com/contents/volumes/V3/TODENTJ-3-154/TODENTJ-3-154.pdf https://opendentistryjournal.com/contents/volumes/V3/TODENTJ-3-154/TODENTJ-3-154.pdf https://opendentistryjournal.com/contents/volumes/V3/TODENTJ-3-154/TODENTJ-3-154.pdf https://opendentistryjournal.com/contents/volumes/V3/TODENTJ-3-154/TODENTJ-3-154.xml J Periodontol Newbrun E 67 555 1996 Newbrun E.
