Erosion Potential of Commercial Fluoride‐Free Mouthwashes on Dental Hard Tissues

International Journal of Dental Hygiene, EarlyView.
ABSTRACT Purpose Mouthwashes often present acidic pH, which raises concerns about their potential contribution to erosive tooth wear. This study evaluated the erosive potential of commercial fluoride‐free mouthwashes using a screening method.

Evaluation of Tooth Erosion Potential of Zero and Carbonated Beverages in Korea: A Laboratory‐Based Study Focused on pH

International Journal of Dental Hygiene, EarlyView.
ABSTRACT Objectives With increasing health consciousness, the consumption of zero‐calorie beverages (zero beverages) is also increasing. Zero beverages are devoid of sugar or alternative sugar content. Tooth erosion possibility continues to be reported in cases of carbonated beverage consumption.

Assessment of Monomer Release From Resin Composites Following the Use of Various Modeling Liquids

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives The chemical composition of resin composites and the use of modeling liquids may influence the release of residual monomer, potentially impacting biocompatibility. This in vitro study evaluated the effect of different modeling liquids on the elution of monomers from two resin composites.
