Abstract

Aim: The aim of this study was to determine the survival rates of questionable and hopeless teeth in patients with aggressive periodontitis (AgP) and chronic periodontitis (CP) during 15 years of supportive periodontal therapy (SPT).

Materials and methods: Thirty-four AgP and 34 CP patients (SPT≥10 years) with bone loss of ≥50% at ≥2 teeth were consecutively recruited. Bone loss was measured on digitized radiographs and teeth were categorized as "questionable" (≥50 to <70% bone loss) or as "hopeless" (≥70%). Progression in pocket probing depths (PPD) during SPT, tooth loss and reasons for extraction were analysed.

Results: In AgP patients, 262 teeth were considered as questionable and 63 as hopeless (CP: 149/51). During active periodontal therapy, 25 questionable and 26 hopeless teeth were extracted (CP: 12/16). During 15.3 ± 4.1 years of SPT of AgP 28 questionable and 15 hopeless teeth were removed (CP: 28/12). The mean tooth loss per patient during SPT in total was 0.14 (AgP) and 0.16 (CP) teeth/year. There were no significant differences in tooth loss or longitudinal progression of PPD between AgP and CP patients.

Conclusions: In patients with AgP, 88.2% (209 of 237) of questionable and 59.5% (22 of 37) of hopeless teeth survived 15 years during regular SPT in a dental school department.
