Guided tissue regeneration in the treatment of XXXX in mandibular molars. A clinical study of degree III involvements.

@entity1 @entity6876 @entity5164
The present investigation was designed to evaluate the regenerative potential of the periodontal tissues in @entity6876 at mandibular molars using a treatment procedure based on the principle of guided tissue regeneration. The @entity1 sample included 21 @entity1 , 26-65 years of age, who presented periodontal lesions in the right and left molar regions including "through and through" @entity6876 . After an initial examination, each @entity1 was subjected to a series of full-mouth scaling and root planing. 2-3 months later, they were recalled for a baseline examination. The furcation-involved molars were randomly assigned in each @entity1 to either a test or a control treatment procedure. The test procedure included the elevation of muco-periosteal flaps at the buccal and lingual aspects of the molars. Granulation tissue was removed and the exposed root surfaces were debrided and planed. The width and the height of the entrance openings to the @entity6876 were assessed. A teflon membrane was adjusted to cover the entrances to the defects (buccal and lingual) and was retained in the manner described by Pontoriero et al. (1988). The flaps were repositioned on the outer surface of the membrane and secured by sutures which were removed after 10 days. Following surgery, the @entity1 were instructed to rinse the mouth twice daily for 4 weeks with @entity5164 . The membranes were removed after a healing period of 1-2 months. A surgical procedure identical to the test procedure was performed in the control tooth regions with the exception of the placement of membranes.(ABSTRACT TRUNCATED AT 250 WORDS)
