Why it matters for dental

Prosthodontists and restorative dentists who prescribe or fabricate occlusal devices need to anticipate accelerated surface degradation and altered flexural strength once the appliances are exposed to gastric acid, potentially shortening service life in patients with reflux or bulimia.

Key points

  • In-vitro study (Journal of Prosthetic Dentistry, available online 24 September 2026) tested occlusal-device materials under simulated gastric-acid pH cycles.
  • Findings quantify changes in flexural strength, elastic modulus, and surface roughness directly attributable to acid exposure.
  • Results apply to night guards, bite splints, and similar PMMA or composite devices routinely delivered in general and prosthodontic practice.
  • No effective date or regulatory action is stated; the paper supplies laboratory data for clinicians to consider in material selection and patient counseling.
