Abstract:
Objective:To evaluate the differences of clinical parameters and putative periodontal patho-gens in sites of different probing depth ( PD) reduction after non-surgical periodontal treatment in patients with aggressive periodontitis ( AgP ) .Methods: Clinical examinations including plaque index , probing depth (PD), attachment level (AL) and bleeding index (BI), and full-mouth periapical photographs were collected from 20 patients with AgP .All the patients received non-surgical periodontal treatment , including oral hygiene instruction , supra-gingival scaling , subgingival scaling and root planing ( SRP ) and were followed up for 6 months post-therapy.Gingival crevicular fluids (GCF) were collected at 1 site in each quadrant before and at the end of 6 months post-therapy .Six kinds of putative periodontal patho-gens and 6 kinds of short chain fatty acids ( SCFAs ) were detected in the GCF samples .Results: The baseline clinical parameters of PD , AL and BI , the baseline concentration of succinic acid , acetic acid , propionic acid and butyric acid , and the prevalence of Treponema denticola were significantly higher in sites with PD reduction more than 2 mm sites compared with PD reduction no more than 2 mm sites [(7.7 ±1.2) mm vs.(5.1 ±1.8) mm, (6.3 ±1.9) mm vs.(4.5 ±2.2) mm, 3.8 ±0.4 vs.3.3 ± 0.8, 1.66 mmol/L vs.1.10 mmol/L, 31.67 mmol/L vs.17.78 mmol/L, 3.31 mmol/L vs.1.95 mmol/L, 84.6%vs.56.1%, P<0.05].However, there were no significant differences in the clinical param-eters, the 6 kinds of putative periodontal pathogen detection and SCFAs concentration between the 2 groups at the end of 6 months post-treatment.In sites with PD>5 mm at the end of 6 months post-thera-py , all were found with red complex bacteria infection .Conclusion:The baseline clinical parameters are important factors in predicting PD reduction after non-surgical periodontal treatment in patients with AgP . In sites with deep pockets after non-surgical periodontal treatment , the active control of red complex bac-teria is recommended .
