  • Characteristics and Evolution of Amphibians

    • Additional characteristics of amphibians include pedicellate teeth (teeth in which the root and crown are calcified, separated by a zone of noncalcified tissue) and a papilla amphibiorum and papilla basilaris (structures of the inner ear that are sensitive to frequencies below and above 10,00 hertz, respectively).
  • Gomphoses

    • As people age and lose their initial set of baby teeth, the new teeth develop gomphoses to anchor them in the jaw.
    • Connective tissues such as the ligaments around the teeth start to dissolve.
    • The goal is to align the teeth evenly to create a strong, healthy bite.
    • Between each adjustment, the teeth and jaw have time to recover.
    • This image illustrates the gomphoses joints of teeth within the jaw.
  • Orthodontics

    • Orthodontists usually use braces and retainers to set teeth.
    • The wires interact with the brackets to move teeth into the desired positions.
    • Invisalign consists of clear plastic aligners that move teeth.
    • Orthodontic treatment can help fix a patient's teeth and set them in the right place.
    • Orthodontists usually use braces and retainers to set the patient's teeth.
  • Periodontal Disease

    • the cementum, or the outer layer of the roots of teeth
    • the alveolar bone, or the bony sockets into which the teeth are anchored
    • Periodontitis involves progressive loss of the alveolar bone around the teeth, and if left untreated, can lead to the loosening and subsequent loss of teeth .
    • A diagnosis of periodontitis is established by inspecting the soft gum tissues around the teeth with a probe and by evaluating the patient's x-ray films to determine the amount of bone loss around the teeth.
    • Regular dental check-ups and professional teeth cleaning as required.
  • Temporomandibular Joint Syndrome (TMJ)

    • On average, the symptoms will involve more than one of the numerous TMJ components: muscles, nerves, tendons, ligaments, bones, connective tissue, and the teeth.
    • Disorders of the teeth can contribute to TMJ dysfunction.
    • Impaired tooth mobility and tooth loss can be caused by destruction of the supporting bone and by heavy forces being placed on teeth.
    • The movement of the teeth affects how they contact one another when the mouth closes; the overall relationship between the teeth, muscles, and joints can be altered.
    • Therefore, there are a variety of treatment approaches including restoration of the occlusal surfaces of the teeth, wearing dental guards to prevent grinding the teeth, and biofeedback exercises to retrain muscle movements, among others.
  • Tooth and Gum Infections

    • Bacteria collect around the teeth and gums in a sticky, creamy-colored mass called plaque, which serves as a biofilm.
    • Grooves on the occlusal surfaces of molar and premolar teeth provide microscopic retention sites for plaque bacteria, as do the approximal sites.
    • Other strains of streptococci adhere strongly to the gums and cheeks but not to the teeth.
    • The gingival crevice area (supporting structures of the teeth) provides a habitat for a variety of anaerobic species.
    • Plaque is a biofilm on the surfaces of the teeth.
  • Dental Caries

    • If demineralization exceeds saliva and other remineralization factors such as from calcium and fluoridated toothpastes, these tissues progressively break down, producing dental caries (cavities, holes in the teeth) .
    • The mineral content of teeth is sensitive to increases in acidity from the production of lactic acid.
    • All caries occur from acid demineralization that exceeds saliva and fluoride remineralization, and almost all acid demineralization occurs where food (containing carbohydrate like sugar) is left on teeth.
    • In most people, disorders or diseases affecting teeth are not the primary cause of dental caries.
    • Thus, when root surfaces of teeth are exposed from gingival recession or periodontal disease, caries can develop more readily.
  • Ingestion

    • The first step to obtaining nutrition is ingestion, a process where food is taken in through the mouth and broken down by teeth and saliva.
    • Once in the mouth, the teeth, saliva, and tongue play important roles in mastication (preparing the food into bolus).
  • Dental Anesthesia

    • The most common local anesthetic technique, effective for the lower teeth and jaw, is inferior alveolar nerve anesthesia.
    • The inferior alveolar nerve runs from the angle of the mandible down the medial aspect of the mandible, innervating the lower teeth, lower lip, chin, and tongue.
    • For this reason, the upper teeth are usually anesthetized locally by injecting lidociane beneath the oral mucosa surrounding the teeth.
  • Characteristics of Mammals

    • Most mammals have heterodont teeth, meaning that they have different types and shapes of teeth rather than just one type and shape of tooth.
    • Most mammals are diphyodonts, meaning that they have two sets of teeth in their lifetime: deciduous, or "baby" teeth, and permanent teeth.
    • Other vertebrates are polyphyodonts: their teeth are replaced throughout their entire life.
