Statement Of Problem: Additional polymerization of indirect composite resins enhances their physical properties but lessens the potential for chemical bonding.
Purpose: The purpose of this in vitro study was to evaluate the influence of different surface treatments and 6-month water storage on the microtensile bond strength (μTBS) of composite resin onlays.
Material And Methods: Composite resin onlays (Filtek Z250) randomly received 6 different surface treatments: (1) airborne-particle abrasion with 27-μm alumina particles+Adper Scotchbond 1XT adhesive application, (2) airborne-particle abrasion with alumina particles+silane application (ESPE SIL)+Adper Scotchbond 1XT, (3) airborne-particle abrasion with alumina particles+Scotchbond Universal adhesive, (4) tribochemical silica coating with 30-μm particles (CoJet Sand)+Adper Scotchbond 1XT adhesive, (5) tribochemical silica coating+silane application+Adper Scotchbond 1XT, and (6) tribochemical silica coating+Scotchbond Universal adhesive. Onlays were luted to fresh composite resin specimens with RelyX Ultimate resin cement. Bonded assemblies were stored in water for 24 hours or 6 months at 37°C and subjected to the μTBS test. Additional surface-treated composite resin onlays were analyzed with a contact profilometer to determine average roughness, and micromorphologic changes were analyzed with scanning electron microscopy.
Results: Airborne-particle abrasion with alumina followed by Adper Scotchbond 1XT or Scotchbond Universal adhesive application provided the highest bond strength values at 24 hours. Lower values were obtained after tribochemical silica coating. After 6 months of artificial aging, airborne-particle abrasion with alumina or silica-coated alumina particles followed by Scotchbond Universal application yielded the greatest bond strength results. Airborne-particle abrasion with alumina produced the highest roughness values and a more irregular surface.
Conclusion: Adhesive selection seems to be relevant to the μTBS of luted composite resin onlays after 6 months of water aging, as specimens treated with Scotchbond Universal, after alumina airborne-particle abrasion or tribochemical silica coating, yielded the highest values and better aging stability.

Purpose: Ultra-high translucency zirconia (UT-Zr) is known for its high esthetic quality; however, its inert surface results in low hydrophilicity and surface energy (SE). To address this limitation, this study proposes an innovative zirconia heat treatment process (ZHTP) and aims to evaluate the effects of ZHTP on the surface characteristics of UT-Zr, offering a novel and practical approach for surface pretreatment in dental practice.
Material And Methods: The plate-shaped UT-Zr samples were fabricated.

Objectives: To compare the impact of intaglio surface treatments - airborne particle abrasion and hydrofluoric acid (HF) etching - of feldspar ceramic (FEL) crowns on the fracture load (FL) and to investigate the effects of abutment materials and artificial aging. The aim was to assess whether etching could be replaced by an alternative surface roughening method.
Materials And Methods: FEL crowns had their intaglio surfaces either abraded (25 µm AlO, 0.

The aim of the study is to assess the impact of mechanical surface treatments on the shear bond strength (SBS) of orthodontic brackets bonded to three-dimensional (3D) printed and milled CAD/CAM provisional materials. Sixty cylindrical samples were fabricated for each provisional material. Samples were treated with one of the following surface treatments: aluminum oxide airborne particle abrasion, diamond bur rotary instrument roughening, and phosphoric acid etching (control).

Statement Of Problem: Polyetheretherketone (PEEK) has been used in clinical dentistry because of its excellent physical and biological properties. However, achieving an effective and durable bond with enamel is challenging because of its chemical inertness and low surface energy, and data on the effects of different surface treatments on the durability of PEEK-enamel bonds are scarce.
Purpose: The purpose of this in vitro study was to investigate airborne-particle abrasion, sulfuric acid etching, and the combined use of these treatments on the bonding durability of PEEK-enamel bonds and to gain a deeper understanding of their bonding mechanism.

Article Synopsis
- - The study explored how different surface treatments affect the bond strength of zirconia with varying yttria contents, using methods like airborne-particle abrasion (APA) and selective infiltration etching (SIE) among others.
- - Results showed that all treated zirconia specimens had higher bond strength compared to untreated ones, with APA being the most effective across all types of zirconia tested.
- - While Zolid Zi (4.5-5.6 wt% yttrium) exhibited the highest bond strength, Zolid FX (9.15-9.55 wt% yttrium) had the lowest, indicating that both treatment method and material type significantly influence bond strength and surface roughness.
