Abstract

|
|
The relationship between occlusion and periodontal health has been extensively studied. However, reports on the effects
of passive eruption using occlusal reduction has not been sufficient. The purpose of the present randomized clinical trial
was to assess the influence of passive eruption using occlusal reduction on the clinical periodontal parameters consisting
of attachment level, pocket depth, tooth mobility, width of keratinized gingiva and osseous defect. The study was performed on 40 teeth of 16 subjects who have been treated for the moderate periodontitis at the Department of Periodontology, Pusan National University Hospital. At the baseline examination, after hygienic-phase and after 6 month from passive eruption using occlusal reduction, clinical parameters were monitored and radiographs were taken. The 20 teeth in the test group received passive eruption using occlusal reduction while the 20 control teeth did not receive any occlusal reduction. The results were as follows; 1) Degree of inflammation of periodontium was improved by initial therapy 2) Teeth received passive eruption using occlusal reduction demonstrated significantly greater reduction in pocket depth, tooth mobility and amount of bone loss, and increase in the width of keratinized gingiva, but no significant changes in the attachment level compared to the control teeth 3) There was significantly greater reduction in pocket depth, mobility, amount of bone loss and attachment level in the test teeth after initial hygienic phase when compared with baseline data. Taken together, these results suggest that the passive eruption using occlusal reduction would be helpful to improve periodontal health.
