[Condition of the periodontium in patients with fixed dentures].

The authors examined 29 patients with fixed prostheses. They investigated the condition of the periodontium of pillar teeth of these dentures and examined the vestibular and oral dental surfaces, the adjacent gingiva and the presence of microbial dental plaque. They recorded also the period of use of the denture. The periodontium was evaluated by Russel's according to Silness-Lö. In 16 dentures the assessed values ware compared with intact teeth on the contralateral side of the same jaw. The values of periodontal indices in pillar teeth of fixed prostheses are higher than in teeth without prosthetic treatment and they are proportional to the standard of hygiene and the period for which the prosthesis has been used.
