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...
Orthodontic forces are known to produce mechanical damage and inflammatory reactions in the periodontium and dental pulp, as well as inflammatory mediators, e.g. prostaglandins, interleukin (IL)-1, IL-6, tumor necrosis factor alpha, and receptor activator of nuclear factor kappaB ligand, in the periodontal ligament (PDL) and dental pulp. We have studied the effects of aging on the production of...
abstract this study investigates the teachers’ correction of students’ spoken errors of linguistic forms in efl classes, aiming at (a) examining the relationship between the learners’ proficiency level and the provision of corrective feedback types, (b) exploring the extent to which teachers’ use of different corrective feedback types is related to the immediate types of context in which err...
Objective: To evaluate the effects of low-level helium-neon (HeNe) laser on cutaneous wound healing in rats. Methods: Sixty Wistar rats were divided into control group and experimental group. A sutured longitudinal, dorsal-medial incision was made, with simple separate stitches. The experimental group was irradiated daily in three areas of the wound with HeNe laser (5mW maximum continuous power...

OBJECTIVE To quantitatively examine the epidermal and dermal cellular and molecular changes that occur after photodynamic therapy of photodamaged human skin. DESIGN Serial in vivo biochemical and immunohistochemical analyses after photodynamic therapy using topical 5-aminolevulinic acid (5-ALA) and pulsed-dye laser treatment. SETTING Academic referral center, Department of Dermatology, Univ...
introduction: to determine efficacy of low level laser therapy for clicking temporomandibular joint (tmj) with a diode laser following orthodontic treatment. methods: performance of lllt with a diode laser for temporomandibular clicking and postoperative findings were evaluated in a case of an orthodontic patient following the termination of treatment. patient had a history of severe clicking ...
objective: low-level laser therapy (lllt) has been increasingly in use over the last few decades in both medicine and dentistry. it has been suggested that lllt may be helpful in pulpal wound healing following pulp exposure. the purpose of this study was to compare the effectiveness of lllt and formocresol (fc) application in healing of remaining pulp following pulp amputation in primary molars...
introduction: the american academy of orofacial pain defined temporomandibular disorders (tmds) as”a collective term that embraces a number of clinical problems that involve the masticatory muscles, the tmj (temporomandibular joint), and the associated structures”. pain and dysfunctional symptoms or signs such as limitations in opening, asymmetric jaw movements and tmj sounds are the most commo...
background and aims. considering the importance of disinfecting dentin after cavity preparation and the possible effect of disinfection methods on induction of various reactions between the tooth structure and the adhesive restorative material, the aim of the present study was to evaluate microleakage of composite resin restorations after disinfecting the prepared dentin surface with nd:yag and...
