As a result, children's teeth generally decayed until they caused pain or infection and removal was required. At that time, the dentists tried to use only hand instruments to open and/or enlarge small cavities and selectively remove the decayed tissue, followed by the placement of a glass ionomer cement , an adhesive filling that also releases ...
These tooth-coloured materials were introduced in 1972 for use as restorative materials for anterior teeth (particularly for eroded areas). [12] The material consists of two main components: Liquid and powder. The liquid is the acidic component containing polyacrylic acid and tartaric acid (added to control the setting characteristics).

Periapical cysts begin as asymptomatic and progress slowly. Subsequent infection of the cyst causes swelling and pain. Initially, the cyst swells to a round hard protrusion, but later on the body resorbs some of the cyst wall, leaving a softer accumulation of fluid underneath the mucous membrane. [citation needed]
Anterior teeth typically do not require full coverage restorations after a root canal procedure, unless there is extensive tooth loss from decay or for esthetics or unusual occlusion. Placement of a crown or cusp-protecting cast gold covering is recommended also because these have the best ability to seal the treated tooth.
Crown lengthening is a technique for increasing crown height of teeth by flap surgery with or without bone surgery. [3] There are two main types: Aesthetic crown lengthening which is performed when a "gummy" smile is an issue for the patient [3] Functional crown lengthening is used to make an unrestorable tooth restorable.
With regard to permanent teeth, there is insufficient evidence to support the use of RMGIC as long term restorations in permanent teeth. Despite the low number of randomised control trials , a meta- analysis review by Bezerra et al. [2009] reported significantly fewer carious lesions on the margins of glass ionomer restorations in permanent ...
