OBJECTIVE Reconstruction of lost attachment apparatus is a major goal of periodontal therapy. Although various osteoinductive bone replacement grafts (BRGs) have been used with apparent clinical success, unequivocal evidence of osteoinductivity may be obtained only through the demonstration of increased osteoblastic/osteoclastic differentiation following(More)
BACKGROUND The effects of periodontal disease on the oral gingival epithelium (OGE) have not been documented fully because they may not be as dramatic as those seen on the junctional epithelium. The aim of this study was to estimate the changes occurring in the OGE with respect to its proliferation and E-cadherin and cytokeratin 19 (K19) expression during(More)
Although the presence of estrogen receptors (ERs) in the gingival tissues has been confirmed, there is as yet insufficient literature regarding its expression in periodontal health and disease. Gingival samples were collected from 40 subjects who were divided into four groups. (Group A, premenopausal health; Group B, premenopausal periodontitis; Group C,(More)
BACKGROUND Cell interaction between dendritic cells (DC) and natural killer (NK) cells in the periodontal milieu is not yet fully known, although these cells are individually known to contribute to the pathogenesis of periodontal disease. MATERIALS AND METHODS Fifty subjects (25 males and 25 females) were included in the study. The subjects were divided(More)
BACKGROUND Epithelial integrity is important for maintenance of periodontal health. It is not fully known if non-surgical periodontal therapy is capable of recreating the epithelial barrier in its functional state. PATIENTS AND METHODS Sixty-five patients (31 males and 34 females) were included in the study. They were divided into group A (healthy gingiva(More)
BACKGROUND AND OBJECTIVE The enamel matrix derivative (EMD) has been used in combination with barrier membranes to optimize regeneration in vertical osseous defects. However, the osteoblast response when exposed to the EMD/barrier membrane combination has not yet been evaluated. The osteoblast behavior when exposed to a combination of regenerative materials(More)
Our traditional understanding of the T-helper (Th)1/Th2 paradigm in periodontal disease has undergone considerable changes in recent years. This review focuses on the Th subsets, including the recently identified cells of the CD4 lineage, their activation pathways and effector function in periodontal disease. The roles of Th17 and regulatory T (Treg) cells(More)
BACKGROUND The purpose of this case study was to evaluate the success and predictability of a rotated papillary pedicle graft in combination with the coronally advanced flap using surgical loupe (2.5X magnification) for the treatment of Miller's class I gingival recession. MATERIALS AND METHODS Fifteen systemically healthy patients with isolated gingival(More)
In this study, infiltrating lymphocytes subpopulation in gingival sections of healthy, inflamed, and periodontitis lesions was investigated. A set of cluster of differentiation (CD) antigen specific monoclonal/polyclonal antibodies to detect different cell types within the tissues was used. These included anti-CD3 (pan T-cell), anti-CD45RO (memory T-cell),(More)
BACKGROUND Multi-rooted teeth with furcation involvement exhibit a poorer prognosis when compared to single rooted teeth. The furcation angle (formed by the divergent roots and the roof) may exert a considerable influence on the accessibility for both home care maintenance and instrumentation during periodontal therapy. As there are few anatomy based(More)
