Pulp capping is a technique used in dental restorations to protect the dental pulp, after it has been exposed, or nearly exposed during a cavity preparation, from a traumatic injury, or by a deep cavity that reaches the center of the tooth, causing the pulp to die. [1]
In dentistry, the configuration factor (or c-factor) refers to the number of bonded surfaces in an adhesive dental restoration.Because adhesive dental restorative material will adhere to the walls of a cavity preparation made available to it during polymerization, competing forces can arise during restoration of the tooth that can have both short and long term effects that correlate to the ...
This procedure is invasive and there is loss of biological dental tissues, which is not required for Hall Technique stainless steel crowns. Dental restoration; this may be a good management option. However, this procedure is invasive and usually requires local anesthetic and tooth preparation (drilling).
The process of preparation usually involves cutting the tooth with a rotary dental handpiece and dental burrs, a dental laser, or through air abrasion (or in the case of atraumatic restorative treatment, hand instruments), to make space for the planned restorative materials and to remove any dental decay or portions of the tooth that are ...
The cavity preparation of a GIC filling is the same as a composite resin. GICs are chemically set via an acid-base reaction. Upon mixing of the material components, no light cure is needed to harden the material once placed in the cavity preparation. After the initial set, GICs still need time to fully set and harden.
The filling seals the cavity preventing food debris and dental plaque stagnating inside the cavity. It also promotes remineralisation of the dental tissues affected by decay. When the cavity is sealed any decay and bacteria that has been left on the floor of the cavity cannot get access to oxygen and sugar and will not continue. [citation needed]
The preparation of opposing cavity walls should be cut in a way to avoid undercuts in order to gain optimum retention from the cavity shape for the indirect restoration. [20] For inlay and onlay preparations that are going to be completed with all-ceramic then these cavity shapes can be slightly over-tapered as most of the retention is gained ...
Dental amalgam is the largest source of mercury received by U.S. treatment plants. [56] The U.S. Environmental Protection Agency (EPA) promulgated an effluent guidelines regulation in 2017 which prohibits most dental practices from disposing dental amalgam waste down the drain. Most dental offices in the U.S. are required to use an amalgam ...
