Gingival and periodontal ligament (PDL) fibroblasts are the major cellular components of periodontal soft connective tissues, but the precise differences between these cells are not yet known. In the present study, we have therefore examined the phenotypic and functional features of the cells obtained from gingival and PDL biopsy samples. Spindle-shaped cells characteristic of fibroblasts were ...

introduction: the purpose of this case report is to analyze the results of vestibuleplasty around an over-denture based on dental implants to determine the evidence on the effectiveness of laser-assisted surgery and soft tissue management in implant dentistry. case report: the patient in this case report was a 57 year- old male who was completely edentulous, with a mandibular over denture based...

introduction: periodontitis is an inflammatory disease, for which, scaling and root planning (srp) is the common approach for non-surgical control of inflammation. using lasers is another approach in the first phase of periodontal treatment for control of inflammation. diode laser has some beneficial effects such as acceleration of wound healing, promotion of angiogenesis and augmentation of gr...

BACKGROUND The potential beneficial effects of extremely low frequency pulsed and sinusoidal electromagnetic fields have been shown on many tissues. Gingival epithelium plays an important role in immunosurveillance of the periodontal tissues. The epithelium acts as a mechanical barrier through cell junctions such as E-cadherin. OBJECTIVES Investigation of the effects of extremely low frequenc...

Alport Syndrome (AS) is an important hereditary disorder affecting the glomerular basement membrane. Diagnosis of AS is based on the presence of hematuric nephropathy, renal failure, hearing loss, ocular abnormalities and changes in the glomerular basement membrane of the lamina densa. The aims of this case report were to show the changes in the gingival tissues in a patient with AS under thera...

introduction: different modalities have been used to achieve better results in wound healing among which are laser and pharmacological agents. to our knowledge, there is no investigation to compare phenytoin and laser together. in this study, we aimed to evaluate laser and phenytoin efficacy and compare their effect on wound healing. methods: we used 60 rats. the animals were divided into 4 gro...

introduction: tinnitus is defined as a perception of sound without an external acoustic stimulus. due to large number of causes and limited knowledge of its pathophysiology, tinnitus still remains an obscure symptom. methods: this was a cross-sectional study on 120 patients with tinnitus and sensorineural hearing loss who were randomly divided into two groups; one group received low-level laser...

Periodontal disease is a pathological inflammatory condition of the periodontal tissues surrounding teeth, including Human Gingival Fibroblasts (HGF) which one major components tissue formation in periodonsium. HGF regeneration with accelerating proliferation engineering therapy needs. Generally, using regenerative materials from cow or pig as therapies, but these have some flaws so this resear...

There are several studies that evaluate the use of lasers in periodontal treatment non-surgical or surgical therapy. However, while showed clinically beneficial effects some treatment, there few clinical reports additional advantages as adjunctive treatments periodontology. The aim this paper is to demonstrate and critically analyze level scientific evidence low-level high-power A narrative rev...
