Healing responses of human intraosseous lesions following the use of debridement, grafting and citric acid root treatment. I. Clinical and histologic observations six months postsurgery.

چکیده
Three block sections of treated human intraosseous lesions within one individual are presented. These lesions were debrided, filled with autogenous grafts and at two sites the root was treated with citric acid. The treated sites were lightly root planed once a month and the blocks were removed 6 months after surgery. In addition, the root accretions within two lesions were notched with a bur prior to root planing in order to positively identify the position of these root accretions in the histologic sections. Clinically, the lesions closed by marginal shrinkage and limited pocket closure. Histologically, regeneration of new cementum, osteogenesis at bone and graft spicule seams and reformation of functionally oriented ligament fibers were present at sites within lesions where accretions had covered the root. Such a healing phenomenon was observed close to the base of the lesions and seemed to be related to this spatial configuration rather than to the notching of the root itself. No specific increased healing responses could be attributed to citric acid root treatment. Thus, "regeneration" of new attachment is possible within human intraosseous lesions even at root sites previously covered by accretions. However, such responses seem to be limited to areas near the base of the intraosseous lesion.

Root coverage with the free gingival graft following citric acid and EDTA
Introduction: Treatment of gingival recession and root coverage of denuded roots is one of the main goals of periodontal treatment. The purpose of this study is evaluation of two root conditioning techniques: EDTA (PH=7,24%) and citric acid (PH=1) in free gingival graft procedure. Methods: In this clinical trial study, 16 patients with 24 class I, II gingival recession (Miller classification)...
متن کاملWhich reconstructive procedures are effective for treating the periodontal intraosseous defect?
Deep intraosseous defects represent a major challenge for the clinician. Sites with intraosseous lesions have been shown to be at higher risk of disease progression in subjects who had not received systematic periodontal therapy (78). Treatments of intrabony defects include scaling and root planing with or without surgical access flap. When the periodontal debridement is surgically performed, a...

Human histologic evidence of periodontal regeneration following treatment of intrabony defects with enamel matrix derivative has yielded inconsistent results in recent case reports. A 46-year-old woman presenting one deep intrabony defect at the distal root of a mandibular first molar scheduled for extraction was selected for enamel matrix derivative therapy. During surgery, a notch was placed ...
