Abstract | AIM: 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.
