Incorporation of Calcium Polyphosphate Sub‐Microparticles in Commercial Toothpastes and Their Effects on Dental Enamel

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Dental bleaching with 35% hydrogen peroxide (HP) can cause deleterious effects on the mineral content of enamel. In this regard, remineralizing submicroparticles of calcium polyphosphate (CaPP) have been investigated for their ability to deposit calcium ions into enamel's hydroxyapatite.

Evaluation of the Integrity of Ceramic Laminates After Adhesive Cementation

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives This study evaluated the effects of resin‐based materials on crack occurrence in ceramic laminate veneers (CLVs) after adhesive cementation. Additionally, the polymerization shrinkage stress (PSS) and maximum polymerization rate (MPR) of the resin‐based materials were determined. Materials and Methods Four resin‐based materials were

The effects of anodization and instrumentation on titanium abutment surface characteristics and biofilm formation

Journal of Prosthodontics, EarlyView.
Abstract Purpose To assess the impact of anodization and instrumentation on titanium abutment surface characteristics (surface roughness and wettability) and biofilm formation (viability and mass). Materials and Methods Titanium discs were obtained from pre‐milled abutment blanks made of titanium‐6aluminum‐7niobium alloy.

Fracture resistance and behavior of endodontically treated maxillary premolars with varying ferrule heights and post numbers: A laboratory study

Journal of Prosthodontics, EarlyView.
Abstract Purpose To investigate how varying ferrule heights and the number of glass fiber posts affect fracture resistance and behavior of endodontically treated maxillary first premolars with substantial loss of tooth structure. Materials and Methods Twenty‐four extracted endodontically treated human maxillary first premolars were divided into three ...

Marginal gap of printed, milled, and heat‐pressed two‐piece polyetheretherketone abutments before and after thermal cycling, and their pull‐off bond strength after thermal cycling

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the marginal gap of two‐piece polyetheretherketone (PEEK) abutments fabricated with different methods, before and after thermal cycling, while also focusing on their pull‐off bond strength. Materials and Methods A two‐piece abutment was virtually designed after digitizing a titanium‐base (Ti‐base) abutment.
