22% vs. aMMP-8 negative median: 13%; p = 0.02).Moreover, a tendency for M-T was found (aMMP-8 positive median: 4.0 vs. aMMP-8 negative median: 3; p = 0.08).The associations of the other periodontal risk-assessment parameters (smoking, diabetes mellitus, PPD, BOP) as well API, and aMMP-8 findings were not significant (p > 0.05). Conclusion:Salivary aMMP-8 findings and periodontal riskassessment parameters, used in SPT, are not associated.The used aMMP-8 POC chairside test appears to provide limited diagnostic benefit in the context of adjusted periodontitis maintenance.
