Tooth loss and alveolar bone crest loss during supportive periodontal therapy in patients with generalized aggressive periodontitis: retrospective study with follow‐up of 8 to 15 years

Abstract

Tooth loss rate was low in GAgP in a regular supportive care programme. Clinical variables improved, and bone loss was minimal over time. Smoking was associated with tooth loss.

Tooth loss in generalized aggressive periodontitis: Prognostic factors after 17 years of supportive periodontal treatment

“…Only 0.14 were lost per year and patient, with overall only 9.5% being lost over the long‐term follow‐up of this study. The annual rate is in line with that reported in previous studies following patients over 8–34 years (Diaz‐Faes et al., ; Graetz et al., ; Saxen, Asikainen, Sandholm, & Kari, ; Waerhaug, ), but also that reported for shorter observation periods (Albandar, Brown, & Loe, ; Bäumer, El Sayed et al., ; Bäumer, Pretzl et al.,; Dopico, Nibali, & Donos, ; Kamma & Baehni, ). It should be noted that while annual tooth loss is affected by the baseline extent (number affected teeth) of the disease (Nibali et al., ), with LAgP patients loosing significantly fewer teeth than those with GAgP (0.05 versus 0.14 per patient and year), our study reports only on GAgP.…”

“…According to a recent meta‐analysis, the long‐term success rate for retaining teeth affected by AgP seems similar compared to that of teeth affected by CP (Nibali, Farias, Vajgel, Tu, & Donos, ). However, compared to data on CP, there are only few long‐term data on tooth survival in AgP (Bäumer, El Sayed et al., ; Bäumer, Pretzl et al.,; Diaz‐Faes, Guerrero, Magan‐Fernandez, Bravo, & Mesa, ; Kratka et al., ; Mros & Berglundh, ; Waerhaug, ), mainly with follow‐up periods of 5 years or less or in mixed LAgP/GAgP populations (Nibali et al., ). Consequently, the question if teeth in AgP patients, especially in GAgP, can be retained until higher age or even lifelong remains unanswered.…”

“…I G U R E 1 Distribution of surviving and extracted teeth in different categories of bone loss (BL) ≤25%, ≤50%, ≤70% and >70% in relation to the BL at baseline (T0) and the last observation (T2 or before extraction during SPT) F I G U R E 2 Survival of teeth with different percentages of bone loss (BL) at T1 (after APT) patients over 8-34 years(Diaz-Faes et al, 2016;Graetz et al, 2011; …”

Clinical performance of non‐surgical periodontal therapy in a large Chinese population with generalized aggressive periodontitis

“…In the present study, the annualized number of tooth loss during SPT can be estimated by the gradient of the smoothing plot (Figure ). The estimated number of annual tooth loss was 0.097 per year, which was consistent to those reported by previous study (Angst ; Baumer et al., ; Diaz‐Faes et al., ; Dopico et al., ; Graetz et al., ; Nibali et al., ). In our future research, the influential factors of periodontal tooth loss of AgP patients will be explored in detail.…”

“…The annualized number of tooth loss of the present study (1.05 per year) was much higher than those of other studies or metaanalysis concerning long-term prognosis of AgP (ranging from 0.09 to 0.27 per year) (Angst 2013;Baumer et al, 2011;Diaz-Faes, Guerrero, Magan-Fernandez, Bravo, & Mesa, 2016;Dopico, Nibali, & Donos, 2016;Graetz et al, 2017;Nibali, Farias, Vajgel, Tu, & Donos, 2013). The primary reason is that the number reported above was the sum of teeth lost during both APT and SPT instead of SPT only reported in previous studies mentioned above.…”
