LONG-TERM EVALUATION OF ENDODONTIC AND PERIODONTAL TREATMENT

One hundred and ninety-five teeth in 35 patients with periodontitis wh o had received both endodontic and periodontal treatment were evaluate d 9 years after endodontic treatment and 8 years after periodontal tre atment, Some 91.4% of cases were well maintained and 8.6% showed a det erioration in their periodontal condition. Twelve of the 195 teeth wit h endodontic treatment were lost, eight for periodontal reasons, three as a result of fracture and one because of caries, and the periodonta l condition of 10 teeth had worsened, An apical lesion formed on one t ooth, The results indicate that the risk of endodontic failure in this group of 195 teeth is very low, and that there is little risk of toot h loss for periodontal reasons, provided that the patients receive sup portive periodontal treatment.
