Özet
Background
Presence of suppuration on gentle probing is considered a clinical sign of active peri-implant inflammation. Identification of associated factors with suppuration may improve timely recognition of peri-implantitis severity.
Methods
This cross-sectional study included 26 patients diagnosed with peri-implantitis. Suppuration on gentle probing was used as the dependent variable. Demographic, systemic and clinical variables were evaluated, including bleeding and/or suppuration on gentle probing, probing depth, radiographic bone loss, and keratinized tissue width. Logistic regression, independent samples t-test, and non-parametric analyses were performed based on the number of patients.
Results
Suppuration on gentle probing was present in 8 of 26 patients (30.8%). In logistic regression analysis including oral hygiene and the presence of edema was significantly associated with suppuration (OR = 21.88, p = 0.043). Regular maintenance visit showed a borderline association (OR = 8.75, p = 0.094). Probing depth was increased in implants with suppuration than in those without suppuration (8.75 ± 2.38 mm vs 7.33 ± 1.50 mm), showing a boundary difference. Radiographic bone loss was increased in implants with signs of suppuration as well (4.88 ± 2.75 mm vs 3.78 ± 2.32 mm) (p > 0.05). Keratinized tissue width was lower in implants with suppuration (0.63 ± 0.92 mm vs 1.72 ± 1.71 mm), with a minimal trend (p = 0.099). Smoking habit, presence of systemic disease, erythema, and bleeding on probing were not associated with suppuration.
Conclusion
Limited to this cohort, the presence of edema appears to be the strongest clinical factor associated with suppuration in peri-implantitis cases. Trends were also observed for increased probing depth, reduced keratinized tissue width, and regular maintenance cases. Larger populations are needed to confirm these associations and related factors.
