[The effects of non-surgical periodontal treatment on the formation of root-dentin hypersensitivity].
OBJECTIVE
To study the effects of non-surgical periodontal treatment on the occurrence of root-dentin hypersensitivity and explore its mechanisms through clinical observations.


METHODS
1453 teeth of 52 patients with chronic periodontitis were given scaling and root-planing procedures. 3 months follow-up of these teeth were taken to find root-dentin hypersensitivity after treatment.


RESULTS
432 teeth of 39 patients had different degree of root-dentin hypersensitivity. However,the symptoms disappeared in most patients after active desensitization treatment.


CONCLUSIONS
Subgingival scaling and root-planing can induce the occurrence of root dentin hypersensitivity,therefore, desensitization treatment should be considered as a part of periodontal treatment plan.
