Periodontal attachment loss
in independently living older adults in Ontario, Canada.
A community study on relationship between stress, coping, affective dispositions and periodontal attachment loss

 However, few studies have assessed the effect of local plaque-retaining factors in the occurrence of periodontal attachment loss in young age cohorts.

While many researchers have attempted to identify risk factors that influence that natural history of progressive periodontal attachment loss and tooth loss, few studies have examined the impact of residual pockets following active treatment on meaningful outcomes.
* Following active periodontal treatment, the presence of residual periodontal pockets (both bleeding and non-bleeding) significantly increases the odds for future periodontal attachment loss and tooth loss.
Dufour LA, Bissell HS: Periodontal attachment loss
induced by mechanical subgingival instrumentation in shallow sulci.
The studies, in subjects with varying degrees of periodontitis, ranged in length from six months to five years, and in part assessed periodontal attachment loss
in sites <4.0 mm, that resulted from various treatments.
Radiographic analysis of alveolar bone height changes may still allow more sensitive evaluation of periodontal attachment loss
compared to changes in probing attachment loss.
