The Relationship Between Bleeding on Probing and Subgingival Deposits. An Endoscopical Evaluation

Abstract

Background:Bleeding on probing (BOP) is an indicator of tissue inflammatory response to bacterial pathogens. 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.

Association Between Low Bone Mineral Density and Clinical Attachment Loss in Japanese Postmenopausal Females

“…In addition to the dental restoration variable, BOP was added as a potential confounder when the outcome variable was AL or PD. Checchi et al 41 demonstrated a direct relationship between BOP and the presence/amount of subgingival deposits. Low systemic BMD was significantly associated with severe AL after controlling for BOP.…”

The effect of smoking on bleeding on probing after nonsurgical periodontal therapy: a quasi-experimental study

“…15,16 This parameter is associated with the presence of biofilm and subgingival calculus, 17 and has been used to indicate the need for subgingival intervention. 18,19 During periodontal maintenance, BoP and probing pocket depth (PPD) are used as prognostic factors for future periodontal disease activity.…”

Prospects of endoscopic technology for diagnostics of inflammatory periodontal disease

“…Для предварительной диагно-стики использовались: зондирование ПК по 3 точкам зон-дом по Williams [1], определение патологической подвиж-ности зубов по Флезару [9]; данные ОПТГ. Для уточнения диагноза у всех пациентов исследовали глубину ПК (по Рамфьерду) [2] под контролем эндоскопа с помощью эн-доскопической системы Perioscopy (Perioscopyinc) [15,24,28,29]. Так же была проведена КЛКТ (фирма производи-тель VATECH, Южная Корея).…”

“…В ка-честве методик сравнения во всех случаях использовались стандартизированные клинические методики: КЛКТ (Vatech) и эндоскопическая диагностика (Perioscopy) [13,15,16,[21][22][23].…”
