background and aims. the aim of this study was to compare the biocompatibility of calcium-enriched mixture ce-ment (cem), composite resin and nano-particled mineral trioxide aggregate (np-mta) using human gingival fibroblasts. materials and methods. a comparative in vitro cell culture study was carried out using 60 single-rooted teeth which were assigned to the following four groups: 1) untreat...

A double-label immunofluorescence technique was used to determine whether all normal fibroblast-like cells cultured from porcine connective tissues simultaneously express both type I collagen and fibronectin (FN). Cells surrounding explants in primary cultures from gingival and periodontal ligament (PL) tissue were heterogeneous in the expression of collagen and FN. Mass population cells at fir...

Human normal, periodontitis and overgrown gingival fibroblasts were assayed concerning proinflammatory cytokines secreting ability. Stimulating effect of gingival overgrowth-inducing drugs such as phenytoin, nifedipine or cyclosporine A and LPS on the secretion ability of each fibroblast specimen was also estimated. The supernatant of cultured medium was assayed cytokines by ELISA techniques. I...

Background: Cigarette smoking is a significant risk factor for periodontal disease. It also causes pigmentation of oral mucosa. The present study was aimed to assess the effects of smoking on lip and gingival pigmentation and periodontal status and the relationship between pigmentation and periodontal parameters. Methods: A total of 109 smokers and an equal number of non-smoker controls (mean a...

Free gingival grafts have been used to repair periodontal deformities resulting from gingival recession. The review of the literature has, however, revealed only a few report of successful root coverage by this technique. The cases of successful root coverage by free gingival grafts technique were presented . In this study, 6 areas of localized gingival recession with root exposure were treated...

BACKGROUND A coronally advanced flap with subepithelial connective tissue graft is the gold standard surgical treatment of gingival recessions, since it offers a higher probability of achieving complete root coverage compared with other techniques. However, optimum short- and middle-term clinical results have also been obtained with coronally advanced flaps alone. The aim of the present study w...

Infection is the primary failure modality for transcutaneous implants because the skin breach provides a route for pathogens to enter the body. Intraosseous transcutaneous amputation prostheses (ITAP) are being developed to overcome this problem by creating a seal at the skin-implant interface. Oral gingival epithelial cell attachment creates an infection-free seal around dental implants. Howev...

common treatment for buccal gingival recession caused by an aberrant frenal attachment includes elimination of the frenum and treatment of the gingival recession by soft tissue graft to increase the width of the attached gingiva that in turn results in root coverage. keratinised gingival, if present in adequate amount, maintains the gingival health by protecting the marginal gingiva. this not o...

Introduction. This paper describes case reports where coronal growth of soft tissue on implant threads was observed after surgery for soft tissue graft. This phenomenon is known as "creeping attachment." Methods. Two patients were submitted to gingival graft procedure including subepithelial connective tissue graft and masticatory mucosal graft. A two-year follow-up appointment was performed. R...
