Correction of a deep-bite malocclusion often confuses orthodontists. Generally, there are 3 ways to correct overbite:intrusion of the incisors, extrusion of the posterior teeth and the combination. However, almost all the conventional methods accompany extrusion of the anchorage tooth as counteracting force, diminishing their clinical effectiveness. Extrusion of the anchorage posterior teeth may increase lower [...]
OBJECTIVE:This aim of this study was to evaluate effect of different methods on cleaning pigment and Candida albicans on heat curing acrylic resin using in denture base in vitro.METHODS:Sixty specimens(10×10×l.3mm) were dyed by coffee, tea and other pigmant from normal food. Then they were contaminated (37℃for 48 hours) by Candida albicans inoculum with 106 colony-forming [...]
Objective:This study was using genetransfer way that treated some disease which had noneffective form routine drugs or traditional therapeutics. And then understand how the effective of VEGF165 plasmid gene expression in tissue at after genetransfer. At the same time we observed pathological change of masseter injury of radiated rats and the level of TGF-β1 gene [...]
Objectives:In access the seeds of T0, T1, T2, T3 generation of transgenic tomato and To generation of transgenic lettuce which including target gene pacA-ctxB and pacP-ctxB, PCR and histochemical staining for GUS activity were used to detect transgenic tomatoes progenies in different growth stages, to explore the genetic stability of the pacA-ctxB and pacP-ctxB in [...]
Periodontitis is a common and chronic inflammatory oral disease caused by bacteria leading to destruction of tissues supporting the teeth. Besides that, the toxins produced by these bacteria and their antigens, inducing the periodontal tissue cells to produce cytokines, increases periodontal Inflammation.as periodontitis’s relation pathogens, actinomyces naeslundii can induce a large amount of tumor necrosis [...]
ObjectiveThe circumstance of skeletal muscle growth is complex, not only by the role of force in different ways, but also by nerve and various cytokines. Research at the cellular and molecular level will help to elucidate the important signaling pathway, which mechanical factors regulate the differentiation of myoblast, and is expected to reveal the mechanism [...]
Objective:To investigate the observation of clinical indicators and the amount of implant neck bone resorption with two different cusp inclination of ITI implants with the CAD/CAM zirconia all-ceramic crown.To observe the prosthetic effects of the ITI implants with the CAD/CAM zirconia all-ceramic crown so as to provide evidence for clinic.Methods:The anterior teeth of 24 patients [...]
Periodontal disease is one of the most common oral diseases which obtain opposite ends for different attitude of patients. It may be improved or quiescent couple with timely integrated medical treatment and actively cooperate with doctor. Conversely, the patient who neglected the dangers of periodontal disease would have to accepted the ends including alveolar bone [...]
Objective:Root canal treatment is the main and the best treatment of pulp disease and periapical disease. But many research in recent years found that the over root canal preparation and filling pressures may result in the root longitudinal fractures of the non-vital teeth, leading to treatment failure. After the root canal preparation by using engine-driven [...]
Objective:This research aims to explore the best power of low-power laser irradiation on implant-osseointegration by observation,analysis of histology and bone histomorphometry, and provide a further scientific basis for the clinical application of a low-power laser in Oral Implantology.Methods:6 female Beagle dogs were selected according to international standards. In accordance with the surgical implanting method of [...]
