Recurrent caries was partly ascribed to lack of antibacterial properties in composite resin. Silver and zinc nanoparticles are considered be broad-spectrum agents. The aim the present study evaluate resins containing 1% silver zinc-oxide on Streptococcus mutans Lactobacillus.Ninety discoid tablets 0%, nano-silver nano particles were prepared from flowable resin (n = 30). discs evaluated by direct contact test. Diluted solutions (PTCC 1683) Lactobacillus 1643) prepared. 0.01 mL each bacterial...
It is difficult to achieve adhesion between resin cement and zirconia ceramics using routine surface preparation methods. The aim of this study was evaluate the effects CO2 Er:YAG laser treatment on bond strength ceramics.In in-vitro 45 disks (6 mm in diameter 2 thickness) were assigned 3 groups (n = 15). In control group (CNT) no used. COL EYL, lasers used for pretreatment surface, respectively. Composite cemented disk dual-curing cement. Shear tests performed at a crosshead speed 0.5...
This experimental study aimed to assess the effect of irradiation red light-emitting diode (LED) and Diode low-level laser (LLL) on osteogenic/odontogenic differentiation stem cells from apical papilla (SCAPs).SCAPs were isolated human tooth root. The groups subjected 4 J/cm2 low level LED in osteogenic medium. control group did not receive any irradiation. Cell viability/proliferation SCAPs was assessed by methyl thiazolyl tetrazolium (MTT) assay days 1 2 (n = 9). Osteogenic evaluated...
Abstract Objectives This experimental study aimed to assess the effect of copper oxide nanoparticles (CuONPs) and light-emitting diode (LED) irradiation on cell viability osteogenic/odontogenic differentiation human SCAPs. Methods After culture SCAPs, effects different concentrations CuONPs were evaluated by methyl thiazolyl tetrazolium (MTT) assay after 24 48 h, optimal concentration was determined ( n = 12). SCAPs then divided into four groups based type treatment: (I) no-treatment control...
Background: This investigation set out to compare the impacts of low-level diode laser (LLDL) and red light-emitting (LED) on survival human dental pulp stem cells (hDPSCs) osteogenic/odontogenic differentiation. Methods materials: In this ex vivo experimental study, groups underwent irradiation LLDL (4 J/cm2 energy density) LED in osteogenic medium. Survival hDPSCs was assessed after 24 48 h (n = 9) using methyl thiazolyl tetrazolium (MTT) assay. The assessment differentiation conducted...
Background and aims. Anticariogenic effects of different mouthrinses have been shown previously. In this in vitro study the anticariogenic polyphenol extract green tea with 0.05% fluoride, 0.2% chlorhexidine fluoride-chlorhexidine were compared. Materials methods. This was performed on 50 maxillary premolars 5 groups: 1) normal saline; 2) a 10% solution extract; 3) fluoride; 4) chlorhexidine; 5) fluoride-chlorhexidine. Each tooth placed tube which contained cariogenic solution. Every day...
Effect of Epigallocatechin Gallate on shear bond strength composite resin to bleached enamel: an in vitro studyObjectives: The aim this study was determine the effect epigallocatechin gallate (EGCG) enamel.Materials and Methods: Ninety enamel surfaces maxillary incisors were randomly divided into 9 groups as follows: G1: control (no bleaching); G2: bleaching; G3: bleaching storage for seven days; G4 -6: application 600, 800 1,000 µmol EGCG-containing solution 10 minutes, respectively; G7 -9:...
Although salivary alkaline phosphatase (ALP) can balance deand remineralization processes of enamel, there is no evidence regarding its effects on the concentrations calcium and phosphate in saliva. The present study aims to determine relationship between ALP activity In this cross-sectional study, we evaluated markers 120 males, ages 19 44 years. All participants provided 5 mL unstimulated whole saliva level enzyme as well were measured using a colorimetric method. Data gathered analyzed by...
Many patients seeking orthodontic treatment already have incipient enamel lesions and should be placed under preventive treatments. The aim of this in vitro study was to evaluate the effect CPP-ACP paste CO2 laser irradiation on demineralized microhardness shear bond strength brackets.Eighty caries-free human premolars were subjected a demineralization challenge using Streptococcus mutans. After demineralization, samples randomly divided into five equal experimental groups: Group 1...
This study aims to synthesize and characterize hydroxyapatite nanoparticles (nano-HA) evaluate their effects on the remineralization of demineralized enamel in presence Er,CR: YSGG laser irradiation.Enamel specimens from 44 human molars were divided into four groups: control, enamel, treated with nano-HA, nano-HA followed by Er,Cr:YSGG irradiation (0.5, 20 Hz, 60 µs, s). Vickers microhardness test was used surface hardness. The morphology chemistry surfaces assessed using scanning electron...
Introduction: Orthodontic treatment has many advantages such as esthetic improvement and self-esteem enhancement; yet it some disadvantages increasing the risk of formation white spot lesions, because makes oral hygiene more difficult. It is rational to implement procedures prevent these lesions. The present study was aimed assess effect CO2 laser fluoride varnish on surface enamel microhardness around orthodontic braces. Methods: Eighty extracted premolar teeth were selected, scaled,...
Background: Dentin conditioning can affect the adhesion of stem cells in endodontic regenerative treatments.This study aimed to assess effects most commonly used irrigants, namely, ethylenediaminetetraacetic acid (EDTA), MTAD, and QMix comparison with Er:YAG laser (as a novel modality for root canal disinfection) on from apical papilla (SCAPs) dentin.Material Methods: Forty dentin specimens were prepared subjected different treatments 5 groups (n=8) control, irrigation EDTA 1 minute, MTAD...
Caries prevention is an important strategy in many countries. Honey has antibacterial activity against cariogenic bacteria and therefore may have less caries than other sugars. This study was conducted to compare the effect of honey with those glucose fructose. In this vitro study, 36 extracted caries-free human premolars were collected prepared following a multistage laboratory process. Then, teeth randomly divided into three groups. Each group put separate tubes containing different...
