Adhesive dentistry is a branch of dentistry which deals with adhesion or bonding to the natural substance of teeth, enamel and dentin.It studies the nature and strength of adhesion to dental hard tissues, properties of adhesive materials, causes and mechanisms of failure of the bonds, clinical techniques for bonding and newer applications for bonding such as bonding to the soft tissue.

Atraumatic restorative treatment (ART) [1] is a method for cleaning out tooth decay (dental caries) from teeth using only hand instruments (dental hatchet and spoon-excavator) and placing a filling. It does not use rotary dental instruments ( dental drills ) to prepare the tooth and can be performed in settings with no access to dental equipment.
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 thickness of smear layer can range from 0.5-2 μmeter and for the smear plug, 1 to 10 μmeter. [3] Smear layer poses some threat for optimal bonding to occur. That is why it needs to be removed. For example, smear layer needs to be removed prior to bonding by etch-and-rinse (total etch) adhesives.
Resin-retained-bridges should be considered when a fixed prosthesis retained by natural teeth is required. [3] The use has been driven by the advent of evidence-based dentistry showing the benefits to patients of reduced tooth preparation and the importance of an intact enamel structure for the long-term health of the teeth.
In the late 1970s, tooth adhesion phosphate monomer 2-methacryloyloxethyl phenyl hydrogen phosphate (Phenyl-P) was developed for tooth-saving restoration techniques. [ 3 ] 4-Methacryloyloxyethyl trimellitic acid anhydride (4-META) that adheres to not only tooth structures but also dental alloys, was developed almost at the same time. [ 4 ]
Apexification is a method of dental treatment to induce a calcific barrier in a root with incomplete formation or open apex of a tooth with necrotic pulp. [1] Pulpal involvement usually occurs as a consequence of trauma or caries involvement of young or immature permanent teeth. As a sequelae of untreated pulp involvement, loss of pulp vitality ...
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 ...
