This study was conducted on 6–18 year-old patients, while a comparable study conducted on mature permanent teeth found success rates of 84.6% using MTA and 92.3% using Biodentine. [35] Calcium hydroxide has also been tested on its use in indirect pulp capping and was found to have a success rate of 77.6%, compared to a success rate of 85.9% ...
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 ...
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 of polyacrylic acid and tartaric acid (added to control the setting characteristics).
The glucose produced from starch by salivary amylase is also digested by the bacteria. When enough acid is produced so that the pH goes below 5.5, the acid dissolves carbonated hydroxyapatite, the main component of tooth enamel. [7] The plaque can hold the acids in contact with the tooth for up to two hours, before it is neutralized by saliva.
Common uses include temporary restoration of teeth, cavity linings to provide pulpal protection, sedation or insulation and cementing fixed prosthodontic appliances. [1] Recent uses of dental cement also include two-photon calcium imaging of neuronal activity in brains of animal models in basic experimental neuroscience .
Dental composites. Glass ionomer cement - composite resin spectrum of restorative materials used in dentistry. Towards the GIC end of the spectrum, there is increasing fluoride release and increasing acid-base content; towards the composite resin end of the spectrum, there is increasing light cure percentage and increased flexural strength.
The choice of luting agent is dependent on clinical factors including dental occlusion, tooth preparation, adequate moisture control, core material, supporting tooth structure, tooth location, etc. [3] Research has determined that no single luting agent is ideal for all applications.
The aim of tooth preparation is to preserve more tooth tissue compared to a crown preparation, while giving an adequate amount of protection to the tooth. 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 ]
