Summary
Bleeding on probing (BOP) indicates gum inflammation. Endoscopic evaluation shows BOP directly correlates with the amount of subgingival plaque and calculus, confirming BOP
Area of Science:
- Periodontology
- Microbiology
- Dental Diagnostics
Background:
- Bleeding on probing (BOP) signifies gingival inflammation due to bacterial pathogens.
- Subgingival microbial deposits beneath the gingival margin are difficult to assess.
- Endoscopy offers a novel, non-traumatic method to visualize the subgingival environment.
Purpose of the Study:
- To investigate the correlation between bleeding on probing (BOP) and subgingival deposits.
- To utilize endoscopy for evaluating the subgingival environment in relation to BOP.
Main Methods:
- 107 teeth from 16 patients were assessed one month post-scaling and root planing.
- Evaluated parameters included plaque index (PI), gingival index (GI), probing pocket depth (PPD), BOP, endoscopic biofilm index (EBI), and endoscopic calculus index (ECI).
Main Results:
- A linear association was found between BOP and probing depth (PD), EBI, and ECI.
- BOP demonstrated high specificity but low sensitivity for detecting subgingival deposits.
- BOP sensitivity was directly proportional to the quantity of subgingival deposits.
Conclusions:
- This study confirms a direct relationship between BOP and the presence/amount of subgingival deposits.
- Further research with larger sample sizes is recommended to validate these findings.
