Dentistry

Dentistry, also known as dental medicine and oral medicine, is a branch of medicine that consists of the study, diagnosis, prevention, and treatment of diseases, disorders, and conditions of the oral cavity, commonly in the dentition but also the oral mucosa, and of adjacent and related structures and tissues, particularly in the maxillofacial area. Although primarily associated with teeth among the general public, the field of dentistry or dental medicine is not limited to teeth but includes other aspects of the craniofacial complex including the temporomandibular joint and other supporti ...

Tertiary dentin

Tertiary dentin forms as a reaction to stimulation, including caries, wear and fractures. Tertiary dentin is therefore a mechanism for a tooth to heal’, with new material formation protecting the pulp chamber and ultimately therefore protects the tooth and individual against abscesses and infection. This form of dentine can be easily distinguished on the surface of a tooth, and is much darker in appearance compared to primary dentine. Tertiary dentine will often not be visible on the surface of a tooth, but because it is more dense it can be viewed on a Micro-CT scan of the tooth. Wear on ...

Abutment (dentistry)

In dentistry, an abutment is a connecting element. This is used in the context of a fixed bridge, partial removable dentures and in implants. The implant fixture is the screw-like component that is osseointegrated.

Aggregatibacter actinomycetemcomitans

Aggregatibacter actinomycetemcomitans is a Gram-negative, facultative anaerobe, nonmotile bacterium that is often found in association with localized aggressive periodontitis, a severe infection of the periodontium. It is also suspected to be involved in chronic periodontitis. Less frequently, A. actinomycetemcomitans is associated with nonoral infections such as endocarditis. Its role in aggressive periodontitis was first discovered by Danish-born periodontist Jorgen Slots, a professor of dentistry and microbiology at the University of Southern California School of Dentistry. Bacterium ac ...

All-on-4

The term All-on-4 refers to "all" teeth being supported "on four" dental implants, a surgical and technique prosthodontics procedure for total rehabilitation of the edentulous patient for patients with badly broken down teeth, decayed teeth or compromised teeth due to gum disease. It consists of the rehabilitation of either edentulous or dentate maxilla and/or mandible with fixed prosthesis by placing four implants in the anterior maxilla, where bone density is higher. The four implants support a fixed prosthesis with 10 to 14 teeth and it is placed immediately, typically within 24 hours o ...

Ameloblastic carcinoma

Ameloblastic carcinoma is a rare form of odontogenic tumor, one that develops in the jawbones from the epithelial cells that generate the tooth enamel. Symptoms include swelling in the jaw and pain, both of which get worse as the cancer grows. It is usually treated with surgery; chemotherapy has not been proven to be effective.
