Air abrasion is a dental technique that uses compressed air to propel a thin stream of abrasive particles—often aluminum oxide or silica—through a specialized hand-piece to remove tooth tissue and decay before being suctioned away, similar to sand blasting.
The tooth is then washed and dried, and the protective material placed, followed finally by a dental restoration which gives a bacteria-tight seal to prevent infection. [ 4 ] Since pulp capping is not always successful in maintaining the vitality of the pulp, the dentist will usually keep the status of the tooth under review for about a year ...
When the root is incompletely formed in adolescents and an infection occurs, apexification can be performed to maintain the tooth in position as the roots develop. In case of non-vital pulp: 1. Isolate the tooth with a rubber dam 2. perform root canal treatment. 3. Mix MTA and insert it to the apex of the tooth, creating a 3 mm thickness of ...
Atomic layer deposition (ALD) is a thin-film deposition technique based on the sequential use of a gas-phase chemical process; it is a subclass of chemical vapour deposition. The majority of ALD reactions use two chemicals called precursors (also called "reactants"). These precursors react with the surface of a material one at a time in a ...
Anodic aluminum oxide, anodic aluminum oxide (AAO), or anodic alumina is a self-organized form of aluminum oxide that has a honeycomb-like structure formed by high density arrays of uniform and parallel pores. The diameter of the pores can be as low as 5 nanometers and as high as several hundred nanometers, and length can be controlled from few ...
Intraosseous anaesthetic injection involves the deposition of anaesthetic solution directly into the cancellous alveolar bone adjacent to the apex of the root of the tooth to be anaesthetised through a small hole. Additionally, more complex dental procedures like surgery or endodontic therapy (like root canals) might make use of it.
Dental plaque is a biofilm that attaches to tooth surfaces, restorations and prosthetic appliances (including dentures and bridges) if left undisturbed.Understanding the formation, composition and characteristics of plaque helps in its control. [6]
Zinc oxide/eugenol cements: Supplied as two pastes or as a powder (zinc oxide) and liquid (zinc acetate, eugenol, olive oil) A slow chelation reaction of two eugenol molecules and one zinc ion to form zinc eugenolate without moisture. However, setting can be completed fast when water is present. Bactericidal effect due to free eugenol
