Tooth loss in treated periodontitis patients responsible for their supportive care arrangements
: journal of clinical periodontology
Aim: To identify risk indicators associated with tooth loss and periodontitis in treated
patients responsible for arranging supportive periodontal care (SPC).
Materials and Methods: Ninety-seven Chinese subjects (34Ã¢â‚¬â€œ77 years) who showed
favourable responses to periodontal therapy provided in a teaching hospital 5Ã¢â‚¬â€œ12 years
previously were recalled. They were advised to seek regular SPC on discharge.
Background information, general health status, smoking, oral hygiene habits, followup
dental care, tooth loss, and periodontal parameters were investigated. Multiple
regression analysis was performed.
Results: Two hundred and fifty-six teeth had been lost, 195 because of self-reported
periodontal reasons. Up to 26.8% sites were with pockets X6 mm. Positive
correlations were found between total/periodontal tooth loss and (i) smoking packyears,
(ii) time spent on oral hygiene, (iii) years since therapyÃ¢â‚¬â„¢s conclusion, (iv) age,
and negative correlations with (v) inter-dental brush use, and (vi) education levels.
Tooth loss by arch was correlated with wearing of removable partial denture in that
arch. Percentage sites with pockets X6mm were significantly negatively correlated
with percentage sites without bleeding on probing.
Conclusions: Smokers, more elderly patients, removable partial denture wearers, and
patients with lower education levels or not using inter-dental brushes ought to be
targeted for clinic-based SPC.
