Aim:
This study aims to analyze factors influencing treatment results in aggressive (AgP) and chronic (ChP) periodontitis.
Methods:
ChP [probing pocket depth (PPD) ≥ 3.5 mm, attachment loss ≥ 5 mm at >30 % of sites; age > 35 years] and AgP (clinically healthy; PPD ≥ 3.5 mm at >30 % of sites, radiographic bone loss ≥ 50 % at 2 teeth; age ≤ 35 years) were examined prior and 3 months after nonsurgical therapy according to the full-mouth disinfection concept. Adjunctive systemic antibiotics were used if Aggregatibacter actinomycetemcomitans had been detected at baseline.
Results:
In 31 ChP (12 female, 10 smokers; 4,808 sites) and 28 AgP (16 female, 9 smokers; 4,769 sites), overall mean PPD reductions were less favorable in AgP (0.9 ± 0.5 mm) than in ChP (1.3 ± 0.4 mm; p = 0.033). PPD reductions and relative vertical probing attachment level gain were more favorable at sites with initial PPD ≥ 6 mm, bleeding on probing, and for adjunctive systemic antibiotics. Furthermore, PPD reductions were more favorable for increased baseline tooth mobility and maxillary teeth, whereas AgP, female sex, and multirooted teeth were associated with less favorable PPD reduction.
Conclusion:
Regarding PPD reduction, AgP responded less favorably to nonsurgical treatment than ChP.
