This study aimed to assess the impact of different laser irradiation modes and photosensitizer types on bactericidal efficacy antimicrobial photodynamic therapy (aPDT). Dentin plates were prepared by sectioning crown dentin bovine teeth infected with Streptococcus sobrinus (n = 11). Nine aPDTs involving combination three 1% solutions photosensitizers (brilliant blue, BB; acid red, AR; methylene MB) semiconductor lasers (50 mW for 120 s, 100 60 200 30 s) performed each plate, control...

The relationship between wear resistance and filler size or loading was clarified for the universal resin composite; however, their in flowable composites has not been clarified. Objectives: purpose of this study to investigate effect on experimental by using a cyclic device. Material Methods: Nine consisting three different sizes (70, 200 400 nm) (50, 55 60 wt%) were prepared. Bowl-shaped cavities prepared flat surface ceramic blocks No. 149 regular cut diamond point. treated with silane...

The purpose of this study was to examine three- and two-body wear values flowable resin composites for posterior restorations, using a mechanical loading device. cavities prepared on flattened extracted molars were restored with (Clearfil Majesty LV: MLV, Estelite Flow Quick: EFQ, Beautifil Plus F00: BFP, MI Fill: MIF) accompanying adhesive systems. A universal composite Majesty) used as control. specimens subjected in vitro testing. MLV showed high value (three-body: 14.69 µm, two-body:...

The purpose of this study was to evaluate pulpal healing and reparative dentin formation after 14 28 days in exposed rat pulp directly capped with an experimentally developed all-in-one adhesive containing surface reaction-type pre-reacted glass-ionomer (S-PRG) filler. four experimental groups the control group were compared using Kruskal-Wallis test, followed by Steel-Dwass post-hoc test compare histopathological score. Mann-Whitney U used score at for each observation item. All adhesives...

The aim of this study was to examine the effect various surface treatments on bond strength a resin luting agent and roughness energy computer-aided design manufacturing (CAD/CAM) materials. Four types CAD/CAM blocks (Shofu Block HC: BHC; GC Cerasmart: CER; VITA Enamic: ENA; Lava Ultimate: LAV) were used. All randomly divided into eight groups based treatment as follows: no (C), airborne-particle abrasion (AA), hydrofluoric acid etching (HA), silane coupling application (SL), AA/SL, HA/SL,...

To ascertain the effects of repeated bonding on shear bond strength orthodontic brackets bonded with a fluoride-releasing and -recharging adhesive system self-etching primer in comparison two other types system.A total 48 premolars were collected divided equally into three groups 16. Each group was assigned one systems: Transbond XT, Plus, or system, Beauty Ortho Bond. Shear measured 24 hours after bracket bonding, bonding/debonding procedures twice first debonding. A universal testing...

We aimed to examine the effect of various adhesive systems on bond strength composite resin enamel or dentin prepared with erbium, chromium: yttrium scandium gallium garnet (Er,Cr:YSGG) laser. Each laser-cut surface was treated a bonding agent (SBB, Group 1); self-etching primer (SBP) and SBB (Group 2 control); phosphoric-acid (KET), SBP 3); KET, sodium-hypochlorite (ADG), 4); all-in-one (TSB, 5); ADG TSB 6). The control group only polished wet silicon carbide papers. shear 5 significantly...

The study aimed to histologically evaluate wound healing of exposed human pulp on direct capping using super-pulsed CO2 laser preirradiation. In this single-blind clinical trial, 28 third molar teeth 17 volunteers were randomly capped with either irradiation (n=14) or Dycal (calcium hydroxide cement; n=14) and restored resin composite. was operated in mode (pulse duration, 0.2 ms; interval, 5.8 0.003 J/pulse). conditions a power output 0.5 W, an time 15 seconds, repeat (10-ms 10-ms...

In this study, morphological shape, elemental distribution and elution properties of Ca, P, Mg in four types calcium phosphate powder were investigated using SEM, EPMA ICP-AES. Calcium powder: OHAp, DCPD, β-TCP OCP observed the white form photopolymerized adhesive monomer they scattered like dispersed fillers resin composite. analysis, CaKα showed a relatively high concentration relation to PKα. each different Ca P. But was almost equal detection limit Namely it suggested that reparative...

This study evaluated the effect of air-blowing variables on microtensile bond strength (μTBS) two all-in-one adhesives. A bonding agent was applied to flat dentin surface extracted bovine teeth, and left undisturbed for 20 seconds. Gentle or intensive five seconds, adhesive photopolymerized 10 Resin composite paste placed cured after each treatment. Specimens were subjected μTBS test with a crosshead speed 1.0 mm/ min. Data statistically analyzed using ANOVA, followed by Bonferroni post hoc...

The studies so far conducted by our colleagues in relation to dental pulp capping using adhesive resins revealed that the are useful for exposed pulps but a little slower take effect on injured tissue during initial stage: up 90-days after exposure, compared with calcium hydroxide and its preparations. In present study, an experimentally developed resin system was applied direct restoration healing process examined histopathologically immunohistochemically. manufactured phosphate added into...
