Dentistry

Dentistry is the known evaluation, diagnosis, prevention, and treatment of diseases, disorders and conditions of the oral cavity, maxillofacial area and the adjacent and associated structures and their impact on the human body. Dentistry is widely considered necessary for complete oral health. Those in the practice of dentistry are known as dentists. Other people aiding in oral health service include dental assistants, dental hygienists, dental technicians, and dental therapists.
Dentistry is that branch of science which deals with the study and practice of diagnosis, prevention, and treatment of diseases of the mouth, the maxilla, and the face.
Surgery
Dentistry usually encompasses very important practices related to the oral cavity. The most common treatments involve the dental surgery on the teeth as a treatment for dental caries. Decayed teeth can be filled with dental amalgam, dental composite, dental porcelain and precious or non-precious metals. Oral and maxillofacial surgery is a more specialized form of dental surgery. Dentists can prescribe medication, x-rays, and devices for home or in-office use. Many oral diseases (such as bilateral odontogenic keratocysts) and abnormalities (such as several unerupted teeth) can indicate systemic, neural, or other diseases. Most general practitioners of dentistry perform restorative, prosthetic, endodontic therapy, periodontal therapy, and exodontia, as well as performing examinations. Many general practitioners are comfortable treating complex cases, as well as placing implants and surgically extracting third molars (wisdom teeth). All dentists must achieve a certain degree of skill in various disciplines in order to graduate from dental school and become an accredited dentist.
Prevention
Dentists also encourage prevention of dental caries through proper hygiene (tooth brushing and flossing), fluoride, and tooth polishing. Dental sealants are plastic materials applied to one or more teeth, for the intended purpose of preventing dental caries or other forms of tooth decay. Recognized but less conventional preventive agents include xylitol, which is bacteriostatic,casein derivatives, and proprietary products such as Cavistat BasicMints.
