Abstract
To evaluate the association between risk scores generated with a simplified method for periodontal risk assessment (Perio Risk), and tooth loss as well as bone loss during supportive periodontal therapy (SPT). Data related to 109 patients (42 males; mean age: 42.2±10.2years, range 22-62) enrolled in a SPT programme for a mean period of 5.6years were retrospectively obtained at two specialist periodontal clinics. Patients were stratified according to Perio Risk score (on a scale from 1 - low risk to 5 - high risk) as calculated at the end of active periodontal therapy. Risk groups were compared for tooth loss as well as the changes in radiographic bone levels occurred during SPT. The mean number of teeth lost per patient during SPT varied from 0 to 1.8±2.5 for patients with a risk score of 1 and 5 respectively (p=0.041). Mean radiographic bone loss during SPT was ≤0.5mm in all risk groups, without significant inter-group differences. Periodontal risk assessment according to Perio Risk may help to identify patients at risk for tooth loss during SPT.
Highlights
The goal of the present study was to evaluate the association between risk scores as assessed according to Perio Risk, and tooth loss as well as bone loss in a large cohort of patients enrolled in a supportive periodontal therapy (SPT) programme
Mean cementum–enamel junction (CEJ)-bone crest (BC) was 3.19 Æ 1.33 mm, and patients had a mean number of teeth with CEJ-BC ≥ 4 mm of 11.2 Æ 7.6
The present study was performed to evaluate the association between risk scores generated with a simplified method for periodontal risk assessment (Perio Risk, Trombelli et al 2009), tooth loss and the deterioration of periodontal conditions under SPT
Summary
To evaluate the association between risk scores generated with a simplified method for periodontal risk assessment (Perio Risk), and tooth loss as well as bone loss during supportive periodontal therapy (SPT). The goal of the present study was to evaluate the association between risk scores as assessed according to Perio Risk, and tooth loss as well as bone loss in a large cohort of patients enrolled in a SPT programme
