background  recent investigations show that both proliferation and secretion of macromolecules by cells can be regulated by low level laser therapy (lllt). the aim of this study was to determine whether lllt could induce a bio-stimulatory effects on human gingival fibroblasts (hgf3-pi 53). therefore, the effect of laser irradiation on human gingival cell proliferation and collagen type i gene e...

Fibroblasts from patients with pulmonary fibrosis express higher levels of the receptor for urokinase, and the extent of fibrosis in some animal models exhibits a dependence on the urokinase receptor. Recent observations have identified the urokinase receptor as a trans-interacting receptor with consequences on signaling and cell responses that vary depending on its interacting partner, the rel...

We have developed two rat mAbs that recognize different subunits of the human fibroblast fibronectin receptor complex and have used them to probe the function of this cell surface heterodimer. mAb 13 recognizes the integrin class 1 beta polypeptide and mAb 16 recognizes the fibronectin receptor alpha polypeptide. We tested these mAbs for their inhibitory activities in cell adhesion, spreading, ...

INTRODUCTION Periodontal diseases are considered as some of the most common reasons of teeth loss, which occur due to the aggregation of microbial plaque and other precipitations on the dental surfaces. In this study, the scaling effect using manual tools, ultrasonic machine and Erbium-Doped Yttrium Aluminum Garnet (Er:YAG)laser on the connection of the human gums connective tissue cells on the...

introduction microbial plaque is the main etiologic factor which causes disease in soft tissue around dental implants. the purpose of this study was to evaluate the effect of plaque on health indicies of soft tissue around dental implants. methods and materials 45 patients with 211 dental implants were examined clinically for four years after prosthodontic treatment. plaque index and health ind...

Background: Gingival anatomic factors, chronic trauma, periodontitis, and tooth alignment are the main conditions leading to gingival recession. The present study was conducted compare root coverage of localized GR using modified coronally advanced flap (CAF) conditioning with 24% EDTA when performed under magnification without magnification. Materials Methods: This on 30 patients Miller’s Clas...

Glucocorticoids (GCs) are frequently used for the suppression of inflammation in chronic inflammatory diseases. Excessive GCs usage is greatly associated with several side effects, including gingival ulceration, the downward migration of the epithelium, attachment loss and disruption of transeptal fibers. The mechanisms underlying GCs-induced impairments in gingival tissue remains poorly unders...

AIM The aim of this report is to present the etiology, diagnosis, and treatment planning strategy in the presence of an open gingival embrasure between the maxillary central incisors. BACKGROUND The open gingival embrasure or "black triangle" is a visible triangular space in the cervical region of the maxillary incisors. It appears when the gingival papilla does not completely fill in the int...

The aim of this study was to determine the efficacy of the lateral advanced flap in root-coverage procedures for mandibular incisors and to evaluate pain after treatment. A total of 15 patients who required treatment for gingival recessions were selected from the University of Genoa Laser and Restorative Dentistry Department. The inclusion criteria were the presence of at least one 3-mm gingiva...
