This study evaluated the effect of shortened application time on long-term bond strength with universal adhesives.Three adhesives were used: Clearfil Universal Bond (CU, Kuraray Noritake Dental Inc, Tokyo, Japan), Scotchbond Adhesive (SB, 3M ESPE, St Paul, MN, USA) or G-Premio (GP, GC Corp, Japan). Sixty molars cut to expose midcoronal dentin and prepared a regular diamond bur. Each adhesive was applied either according manufacturer's instruction time. Specimens stored in distilled water at...
Purpose To evaluate the effects of double application self-etch adhesives on their microtensile bond strength (μTBS) to dentin, as well hardness (H) resin-dentin interfacial structures. Materials and methods Midcoronal dentin surfaces (n = 45) were polished with 180-grit SiC paper randomly allocated 9 groups based three - Scotchbond Universal Adhesive (SB), G Premio Bond (GP), Clearfil Megabond 2 (MB) modes: single (S), light curing after each (DL), only at end (D). Following composite-resin...
To evaluate the effect of pre-procedural antiseptic mouthwashes on dentin bond strength different adhesive systems. Flat occlusal surfaces from 120 extracted human molars were randomly divided into four groups according to (0.12% chlorhexidine = CHX, 1% hydrogen peroxide HP, 0.2% povidone-iodine PI, and no mouthwash/control) three subgroups adhesives used (Clearfil SE Bond; CSE, Single Bond Universal SBU in etch-and-rinse (ER) or self-etch (SE) modes) (n 8). Composite resin was built up, all...
Abstract Background Successful restorative procedures, particularly for patients undergoing head and neck radiotherapy, rely on a robust adhesive interface. Since radiotherapy may alter dental tissues compromise bonding, this study evaluated how the timing of radiation exposure affects microtensile bond strength (µTBS) universal to dentin with different application modes. Methods Forty-two human third molars were used in study. Mid-coronal was prepared using low-speed saw polished silicon...
The purpose of this study was to evaluate the effect surface roughness and smear layer on micro-shear bond strength (µSBS) two self-etching adhesives, Clearfil SE Bond (SE) Tri-S (S3). Flat dentin surfaces were prepared with SiC papers (600-, 180- 120-grit) diamond burs (extra fine, medium coarse). They further divided into smear-covered smear-free bonded respective adhesives. µSBS test performed after water storage at 37ºC for 24 h. Smear thickness measurement evaluated by scanning electron...
The purpose of this study was to evaluate the microtensile bond strength (µTBS) a newly developed resin cement, ECD-89 (ECD, Tokuyama Dental, Tokyo, Japan) dentin and observe interfacial micromorphology by comparing with two commercial cements, Multilink Automix (MA, Ivoclar Vivadent AG, Schaan, Liechtenstein) Panavia F2.0 (PF, Kuraray Noritake Japan). Flat surfaces human third molars were exposed using #600 SiC. After application primer cement surface, each applied cured light (light...
Using transmission electron microscopy (TEM), this study investigated the characteristics of smear layers after preparation dentin surfaces using different methods. In addition, analyzed, scanning (SEM), interactions with various acidic agents used subsequently to treat surface. Mid‐coronal were prepared according one five instrumentation methods: fracture; grinding carbide bur; regular‐grit diamond superfine‐grit or 600‐grit silicon (SiC) abrasive paper. Then, each surface was further...
This study evaluated an experimental two-step self-etch adhesive (BZF-29, BZF) by comparing it with a reference (Clearfil Megabond 2, MB) and universal (G-Premio Bond, GP) for microtensile bond strength (μTBS) resin-dentin interfacial characteristics. Twenty-four human third molars were used the μTBS test. Bonded peripheral dentin slices separated to observe interface measure layer thickness SEM. data of central beams obtained after 24 h 6 months water storage. Fracture modes determined...
Online learning has become an effective approach to reach students who may not be able travel university campuses for various reasons. Its use also dramatically increased during the current COVID-19 pandemic with social distancing and lockdown requirements. But online education thus far been primarily limited teaching of knowledge cognitive skills. There is yet almost no physical clinical skills.In this paper, we present a shared haptic virtual environment dental surgical skill training. The...
To evaluate the long-term effect of different surface treatments on repair microtensile bond strength (µTBS) resin composite using a universal adhesive.Thirty-six blocks were fabricated and aged in 37°C distilled water for 1 month. The randomly assigned to treatments: no treatment (control); diamond bur grinding (D); + phosphoric acid cleaning (DP); silane application (DSi); (DPSi); grit blasting with 50 µm H3PO4 particles (APSi). Thereafter, Single Bond Universal adhesive was applied...
This study evaluated the effect of topical fluoride application on enamel hardness after in-office bleaching. Twelve human incisors were cut along long axis, resulting in 24 halves used four treatment groups (n = 6 each group): (i) untreated group (C); (ii) bleaching material (B); (iii) with surface reaction-type prereacted glass-ionomer varnish (B+PRG); and (iv) acidulated phosphate solution (B+F). All specimens subjected to pH-cycling for 4 wk. Knoop was measured using a Cariotester. The...
This study evaluated the effects of dehydration on mechanical properties adhesive resins and dentin, microtensile bond strength (µTBS) adhesives. Third molars were randomly bonded with Clearfil Mega Bond (MB) or SE 2 (SE). After water-storage (37°C; 24 h), µTBS was obtained in 'wet' (tested after 5 min removal from storage) 'dehydrated' 10, 15 h) conditions by a universal tester (crosshead speed: 1 mm/min). Data analyzed two-way ANOVA Duncan's test. Hardness (H), Elastic modulus (E)...
SUMMARY Objective: To evaluate the effect of different bonding protocols on microtensile bond strength (μTBS) a universal adhesive to dentin contaminated with hemostatic agent. Methods and Materials: Ninety-five extracted premolars were used in this study. For μTBS test, 80 teeth cut expose mid-coronal randomly divided into two groups (uncontaminated agent-contaminated dentin). Each group was further five subgroups (n=8/group): 1) SE: no additional treatment, 2) ER: etching 32% phosphoric...
This study aimed to compare the effect of silver diamine fluoride (SDF) and varnish (NaF) on Vickers microhardness (VHN) enamel dentin after radiotherapy pH-cycling. Human premolars were cut longitudinally, embedded serially polished. The VHN enamel/dentin irradiated evaluated. specimens treated with either NaF or SDF, subjected pH-cycling then test for 4 days. Consequently, they energy-dispersive X-ray (EDX) analysis. Radiation adversely affect (p<0.05), whereas was not affected (p>0.05)....
To evaluate whether varying thicknesses of universal adhesives utilizing the additional coating strategy would affect their microtensile bond strength (µTBS) to dentin, hardness, and elastic modulus (mechanical properties).Ninety-nine human maxillary premolars were cut expose coronal ground with regular-grit diamond burs, randomly distributed into 9 groups based on 1. adhesive: Scotchbond Universal Adhesive (SB; universal), G Premio Bond (GP; universal) Clearfil Megabond 2 (MB; two-step...
