Comparative evaluation of impact strength of mechanically modified heat polymerized polymethyl methacrylate (PMMA) resin with addition of 0.5, 1, 2 wt% of silver nanoparticles (AgNPs): An in-vitro study.

Objective: Polymethyl methacrylate (PMMA) is one of the most widely used denture base material because of favorable esthetics and desirable characteristics such as easy handling. Acrylic resins, although, have some inherent disadvantages such as relatively poor physical and mechanical properties. The objective of the present study was to evaluate and compare the impact strength of unmodified and modified heat cure PMMA-based denture base material with addition of different concentrations of silver nanoparticles (AgNPs) (0.

Role of Dental Professionals in the Management of a Dentigerous Cyst in a Patient With Amelogenesis Imperfecta.

Amelogenesis imperfecta (AI) is a hereditary condition that affects the clinical features and structure of the enamel. The enamel formation diseases are inherited and might be X-linked, autosomal dominant, recessive, sex-related, or sporadic. Dental professionals should evaluate such patients completely, both clinically and radiographically, to detect any cysts associated with impacted or unerupted teeth.
