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 ...
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).
Osteo-odonto-keratoprosthesis (OOKP), also known as "tooth in eye" surgery, [1] is a medical procedure to restore vision in the most severe cases of corneal and ocular surface patients. It includes removal of a tooth from the patient or a donor.
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 ...
Guided bone regeneration (GBR) and guided tissue regeneration (GTR) are dental surgical procedures that use barrier membranes to direct the growth of new bone and gingival tissue at sites with insufficient volumes or dimensions of bone or gingiva for proper function, esthetics or prosthetic restoration.
It was Bindl and Mörmann [2] who named this restorative procedure "endocrown" in 1999, defining it as a total porcelain crown fixed to a depulped posterior tooth, which is anchored to the internal portion of the pulp chamber and to the cavity margins, thus obtaining macromechanical retention (provided by the pulpal walls) for restoring endodontically treated teeth.
These teeth often have thin root canal walls which are susceptible to fracture after treatment. Therefore, complete cleaning and shaping as well as obturation of these teeth are difficult or sometimes impossible, due to high risk of fracture during the procedure [ 48 ] Clinical outcome of regenerative endodontics can be observed within 6 months ...
