Abstract Dental hypersensitivity due to exposure of dentinal tubules under the enamel layer saliva is a very popular and highly elusive technology priority in dentistry. Blocking water flow within exposed key principle for curing dental hypersensitivity. Some salts used “at home” solutions remineralize inside by concentrating ingredients. An “in-office” option applying dense resin sealants on tubule entrance has only localized effects well-defined sore spots. We report self-assembled film...

Dentin hypersensitivity is sharp and unpleasant pains caused by exposed dentinal tubules when enamel outside of the tooth wears away. The occlusion via in situ remineralization hydroxyapatite best method to alleviate symptoms dentin hypersensitivity. Commercially available dental desensitizers are generally effective only on a specific area relatively toxic, their performance usually depends skill clinician. Here, facile efficient treatment with remarkable aesthetic improvement inspired...

The blending effect (BE) plays an important role in esthetics of the composite resin. objective this study was to determine extents which filler size and content affect BE. Three types fillers (0.7, 1.0, 1.5 µm) were mixed at weight contents 60, 70, 75, 80%. This simulated clinical class 3 or 4 cavities quantitatively measured color diffusion objects next based on CIELab space. For each size, there a trend increasing BE as increased. translucency parameter (TP) exhibited opposite decreasing...

Objectives. This study was conducted to determine the minimum thickness of opaque-shade composite resin required mask discolored tooth structures or darkness oral cavity and effect brand shade resins on masking ability translucency. Materials methods. Discs beveled specimens were manufactured using six light-curing (Charisma, Heraeus Kulzer; Estelite Sigma Quick, Tokuyama; Gradia Direct Anterior, GC). The reproduced background tiles. disc specimen colors measured a spectroradiometer by...

The purpose of this in vitro study was to compare the accuracy various 3D printers and a milling machine.The die model designed using CAD (Autodesk Inventor 2018 sp3). 30 µm cement space given ideal crown mandibular left first molar (ExoCAD). crowns were produced machine (Imes-icore 250i) (Zenith U, Zenith D, W11) they divided into four groups. In all groups, interior each scanned (Identica blue) superimposed (Geomagic Control X) with previously die. difference between actual measured at...

Objective. The purpose of this study was to compare the cytotoxicity four denture adhesives on human gingival fibroblast cells. Materials and methods. Immortalized fibroblasts were cultured with one different adhesives, Polident, Protefix, Staydent or Denfix-A, which placed in insert dishes (10% w/v concentration) for 48 h. MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] assay flow cytometric apoptosis used evaluate cell viability rates. also examined under a scanning...

Tannin–metal chelates for the efficient nucleation of hydroxyapatite and an aesthetically improved solution dentinal hypersensitivity treatment.

The aim of this study was to evaluate the fracture resistance fatigued lithium disilicate pressed zirconia crowns versus other ceramic crowns.Lithium zirconia, fluorapatite monolithic disilicate, and were fabricated. Cyclic static loadings applied mesiobuccal cusp tip after thermocycling strengths recorded.Fatigued found have a 9,117.81 ± 727.04 N, compared with 9,240.61 887.21 N for crowns, 3,030.18 1,505.83 4,173.94 877.46 (P = .001).This in vitro shows that better than crowns.

The aim of this study was to directly measure the temperature drill during implant site preparation. measured compared that previously reported inside bone. change using a thermocouple inserted stainless steel an 18-gauge needle and mercury-containing slip ring. Three thermocouples were into bone with different depths 10 mm, 5 mm 1 mm. 0.5 away from periphery drilled hole diameter 3.4 rotating speed varied 500 rpm 2000 rpm. Each drilling procedure performed times, average calculated....

Zirconia has recently become one of the most popular dental materials in prosthodontics being used crowns, bridges, and implants. However, weak bonding strength adhesives resins to zirconia surface been a grand challenge dentistry, thus finding better adhesion is urgently required. Marine sessile organisms such as mussels use unique priming strategy produce strong wet mineral surfaces; distinctive chemical features mussel’s adhesive primer proteins high catechol contents among others. In...

The control of macrophage polarization is important in bone tissue regeneration such as osseointegration. In this study, a coating method was developed to improve the osseointegration titanium (Ti) implants by generating an immunomodulatory effect. surface Ti discs coated with poly(lactide-co-glycolide)(PLGA) polymer, phosphatidylserine (PS), and arginine-glycine-aspartic acid (RGD) peptide conjugated phospholipid. vitro assay using mouse marrow-derived macrophages (BMDMs), most significant...

Many adults suffer from dentin hypersensitivity during their lifetime, which causes intense and unpleasant pain. A facile efficient treatment is presented by J.-S. Ahn, D. S. Wang, team on page 919. The approach based complexes of gallic acid metal ions, inspired the tunicate-self healing process.

The aim of this study was to analyze the load distribution interim restorations using healing cap during immediate loading implant treatment in vitro. A total 29 models with which were fabricated selected. pull-out strength measured a used and new cap. compressive sinking distance also measured. restoration showed lower value (max. 29.8 N) compared natural bite force. amounts larger than normal tooth sinking. on roughly 3 times (0.3–0.5 mm under 450 those teeth. plastic would be useful for treatment.
