Abstract
This study was carried out to investigate the effect of definitive curettage after initial preparation.
Definitive curettage was performed for 147 anterior teeth (25 sextants), at which the alveolar bone showed horizontal resorption, at one month after initial preparation. Probing depth, attachment level, level of gingival margin, bleeding index, gingival index and mobility were measured from the base-line level 2 months after definitive curettage and the results were analyzed statistically.
The results were as follows:
All clinical measurements were showed a improved condition by initial preparation. The reduction of probing depth depended primarily on a decrease in gingival recession.
By definitive curettage following initial preparation, all clinical measurements were further improved. This improvement in probing depth was mainly based on an attachment gain.
The above results suggest that definitive curettage is useful for the treatment of pockets above the level of bone on single rooted teeth.
