Abstract

Aim: The aim of this retrospective study was to assess teeth with a poor prognosis and the proximal periodontium of adjacent teeth, and to identify the risk factors associated with the loss of teeth with a poor prognosis following non-surgical periodontal treatment. Material and Methods: Teeth with a poor prognosis (n=113), teeth adjacent to those of poor prognosis (n=105) and non-adjacent teeth (n=51) were evaluated in 25 non-smoking patients who had received supportive periodontal treatment for 5-16 years following non-surgical periodontal treatment at a university hospital. Results: Probing pocket depth (PPD), percentage of alveolar bone loss, presence of tooth mobility and bleeding on probing in all teeth improved significantly after treatment. Logistic regression analysis showed that loss of teeth with a poor prognosis depended on the initial deepest PPD, tooth mobility and multi-rooted tooth. Conclusions: Teeth with a poor prognosis did not affect the proximal periodontium of the adjacent teeth, and progression of periodontal disease in these teeth and adjacent teeth can be prevented by non-surgical periodontal treatment in non-smokers. The risk factors for loss of teeth with a poor prognosis were the initial deepest PPD, tooth mobility and multi-rooted tooth.
