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.
For these patients, dental prophylaxis and regular monitoring are the primary recommended treatment steps which will help prevent future risk of infection. [8] Symptomatic patients may receive treatment options that include surgical curettage with bleeding stimulation or pulp vitality testing in areas showing periapical inflammation. [8]
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 ...
Because dental pain is a late finding, many lesions are not detected early, resulting in restorative obstacles and increased tooth loss. [ 3 ] Cementicles are small, spherical or ovoid calcified masses embedded within or attached to the cementum layer on the root surface of a tooth, or lying free within the periodontal ligament .
Human Tooth Diagram. Cementoma is an odontogenic tumor of cementum.It is usually observed as a benign spherical mass of hard tissue fused to the root of a tooth. [1] It is found most commonly in the mandible in the region of the lower molar teeth, occurring between the ages of 8 and 30 in both sexes with equal frequency . [1]
Ankylosis is common in the anterior tooth after trauma and can be referred to as replacement resorption. In this process PDL cells are destroyed and as a result the cells of the alveolar bone will perform most of the healing. Radiographic examination of a patient with ankylosis may also reveal a loss of the PDL and bony bridging. [citation needed]
In animal tooth development, cementogenesis is the formation of cementum, one of the three mineralized substances of a tooth.Cementum covers the roots of teeth and serves to anchor gingival and periodontal fibers of the periodontal ligament by the fibers to the alveolar bone (some types of cementum may also form on the surface of the enamel of the crown at the cementoenamel junction (CEJ)).
Regenerative endodontics has 3 critical steps: adequate disinfection of the root canal system, induction of bleeding through overinstrumentation to create a scaffold for stem cells, and coronal sealing of the blood clot with a biocompatible material, such as mineral trioxide aggregate. The procedure is applied in two visits as follows: [50]
