BACKGROUND The purpose of this study was to histologically evaluate the healing of surgically created Class II furcation defects treated using an autogenous bone (AB) graft with or without a calcium sulfate (CS) barrier. METHODS The second, third, and fourth mandibular premolars (P2, P3, and P4) of six mongrel dogs were used in this study. Class II(More)
AIM This study histologically analysed the effect of autogenous platelet-rich plasma (PRP), prepared according to a new semiautomatic system, on healing of autogenous bone (AB) grafts placed in surgically created critical-size defects (CSD) in rabbit calvaria. MATERIAL AND METHODS Sixty rabbits were divided into three groups: C, AB and AB/PRP. A CSD was(More)
OBJECTIVE The purpose of this study was to histologically analyze the influence of bioactive glass and/or a calcium sulfate barrier on bone healing in surgically created defects in rat tibias. MATERIAL AND METHODS Sixty-four rats were divided into 4 groups: C (control), CS (calcium sulfate), BG (bioactive glass), and BG/CS (bioactive glass/calcium(More)
BACKGROUND The purpose of this study was to histologically evaluate the healing of experimental dehiscence defects after surface demineralization with tetracycline hydrochloride. METHODS Six adult male monkeys (Cebus apella) were used in this study. Dehiscence defects were surgically created on the buccal aspect of the mandibular lateral incisors in all(More)
OBJECTIVES The aim of the present investigation was to histologically analyze the effect of using lyophilized bovine bone (GenOx® organic matrix) with (or without) guided tissue regeneration (using a decalcified cortical osseous membrane [GenDerm®]) on bone healing in surgically created critical-size defects created in rat tibia. MATERIAL AND METHODS(More)
BACKGROUND Severely resorbed mandibles often present a short band of keratinized tissue associated with a shallow vestibule. As a result, prominent muscle insertions are present, especially in the mental region of the mandible. This case report describes the deepening of the vestibular sulcus in an atrophic mandible by combining free gingival grafts(More)
