BIS GMA Meaning and
Definition
-
Bis GMA, also known as Bisphenol A-glycidyl methacrylate, is a dental resin commonly used in various restorative and cosmetic dental materials. It is a key ingredient in dental composites, sealants, and adhesives.
Bis GMA is a type of dimethacrylate monomer that consists of two bisphenol A units joined together by a glycidyl methacrylate spacer. It is a viscous liquid that can be polymerized to form a hard and durable material.
In dentistry, Bis GMA is renowned for its excellent mechanical properties, such as high toughness, wear resistance, and strength, making it suitable for use in dental fillings and restorations that are subjected to substantial chewing forces. It possesses a low shrinkage rate during polymerization, reducing the risk of gapping or cracking in the restored tooth.
Furthermore, Bis GMA allows for good adhesion to tooth structure due to its methacrylate groups, which enable chemical bonding with enamel and dentin. This enhances the longevity of dental restorations by ensuring a stable and reliable bond between the tooth and the restorative material.
However, it is worth noting that Bis GMA has raised concerns regarding potential health risks related to its monomeric form, bisphenol A, which has been associated with endocrine disruption. Nonetheless, in its polymerized state, Bis GMA is considered safe for use in dentistry when employed according to current standards and regulations. Dental professionals follow stringent protocols and safety measures to minimize patients' exposure to uncured monomers during dental procedures.

Etymology of BIS GMA
The word "Bis-GMA" is an acronym that stands for "Bisphenol A-glycidyl methacrylate". Let's break down the etymology of each component:
1. Bisphenol A: "Bisphenol A" refers to a compound made up of two phenol groups (a type of organic molecule) connected by a bridge. The term "bisphenol" originates from the combination of "bis" (meaning "twice" or "double" in Latin) and "phenol" (referring to a specific type of organic compound).
2. Glycidyl: "Glycidyl" comes from "glycidol", which is a compound composed of a glycidyl group attached to a hydroxyl group (a type of functional group in organic chemistry).
