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 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 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)
Isolated lesions of gingiva arise in succession to the hyperinflammatory reactions in response to the underlying local irritants. Despite their overlapping clinical and histological features, these lesions are distinctive regarding their biological behavior. Recurrence has been reported after surgical excision because of the incomplete removal of underlying(More)
BACKGROUND The differentiation of naοve T helper (Th) cells towards Th17 and regulatory T cells (Treg) is regulated by the transcription factors retinoic acid related orphan receptor gamma transcription (RORYt) and Forkhead box p3 (Foxp3), respectively. An imbalance in the activity of these transcription factors could result in the dysregulation of(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)
T helper (Th) cells have an important role in host defence as well in the pathogenesis of periodontal disease. Th cells differentiate from naive cells into various subsets, each of which is associated with a set of inducing and effector cytokines. Previously, it was thought that this differentiation was an irreversible event. Recent evidence suggest that(More)
BACKGROUND Simvastatin (SMV) is one of the cholesterol-lowering pharmacological drugs. Recent studies demonstrate that it has a bone stimulatory effect. The present study was designed to investigate the effect of SMV along with collagen membrane on osteoblast-like SaOS-2 cells and also to standardize the dosage of SMV to be incorporated into the collagen(More)
BACKGROUND Periodontal plastic surgical procedures aimed at coverage of exposed root surface have evolved into routine treatment modalities. The present study was designed to evaluate the effectiveness and predictability of using a collagen barrier along with a demineralized bone matrix in the treatment of recession defects in a single surgical procedure.(More)
