Abstract
Two regenerative surgical approaches using citric acid conditioning, were compared in the treatment of deep intraosseous periodontal defects. The 1st approach was non-resective in that no osseous tissue was removed. The 2nd, a partially resective approach, involved reduction of the osseous defect depth by removal of some supporting bone. A total of 26 defects in 16 patients, with probing pocket depth .gtoreq. 7 mm, were included in the study. The depths of the corresponding osseous defect, as revealed during surgery were .gtoreq. 5 mm. The results demonstrated mean gains in probing attachment level of 0.7 mm for the partially resected group and 1.1 mm for the non-resected group. Corresponding gains in probing bone levels were recorded in the defect sites for each group. Probing pocket depth was reduced from 7.5 mm to 4.0 mm in the partially resected group and from 7.9 mm to 5.3 mm in the non-resected group. Both procedures caused loss of attachment and bony support from adjacent tooth surfaces involved by the surgical procedure. Slightly more loss of attachment and bone was experienced by the partially resected group (range 1.2-1.5 mm) than by the non-resective group (range 0.1-0.9 mm).
