Sealing in dentistry
The term obturar in dentistry is used to define what is commonly known as "empastar" and that is to clean the cavity resulting from a caries and then to fill it with some material. This process thus rehabilitates the dental anatomy for proper aesthetics, function, mastication and occlusion of the teeth with their antagonists and obtain a good seal that prevents the carious lesion from recurring.
Types of dental fillings
The most common are composite resins, amalgam, cohesive gold (disused), glass ionomers, compomers and dental cements such as calcium hydroxide, zinc oxyphosphate and eugenol. What is commonly known as "filling" today is often made with composite resins or, previously, with silver amalgam. The latter have fallen into disuse due mainly to their lack of aesthetics and their supposed toxicity which is not recognized by the American Dental Association (ADA) or practically all dental communities in the world; The rest are for temporary seals, while a treatment is usually finished or developed, usually in endodontics.
