Glossary of Dental Clinical and Administrative Terms There are many terms used daily by dentists and their staff in the course of delivering care to patients, maintaining patient records and preparing claims. Many terms are familiar, especially to experienced individuals. New dentists and staff, however, may not be as familiar – and over time new terms come into use and old terms are revised for clarity. The ADA's Council on Dental Benefit Programs has included a glossary of dental clinical and administrative terms in each edition of the CDT manual. Although glossary information in the printed CDT Manual serves a legitimate purpose, the online version of the Glossary has the advantage of being readily updated. This online glossary contains the Council's most current set of terms and definitions. Content is based on the CDT 2011-2012 glossary, with some changes (e.g., definitions of inlays and onlays) that came about after the manual was printed.

1. Dental Terminology For Dummies Manual

Apr 11, 2014 - Practice doctor has produced a practice manual for over ten years. It uses dental terminology and standards and it is anticipated that it will.

The Council intends to keep this glossary current, and include its contents in the next CDT manual. Please check this page for the latest information.

Updates will continue as long as the terms used by dentists and their staff continue to expand and evolve.

This frequently includes all insurance company services (actuarial services, underwriting, benefit description, etc.) except assumption of risk. Administrator: One who manages or directs a dental benefit program on behalf of the program's sponsor.

Adult dentition: The permanent teeth of adulthood that either replace the primary dentition or erupt distally to the primary molars. Adverse selection.

The ADA House of Delegates adopted and has published anesthesia policy and guidelines, which are available online. (PDF).

(PDF). (PDF) Select definitions from the policy and guidelines follow. Please refer to the cited sources for complete and current information. Methods of Anxiety and Pain Control analgesia–the diminution or elimination of pain. Deep sedation–a drug-induced depression of consciousness during which patients cannot be easily aroused but respond purposefully following repeated or painful stimulation.

The ability to independently maintain ventilatory function may be impaired. Patients may require assistance in maintaining a patent airway, and spontaneous ventilation may be inadequate. Cardiovascular function is usually maintained.

General anesthesia–a drug-induced loss of consciousness during which patients are not arousable, even by painful stimulation. The ability to independently maintain ventilatory function is often impaired. Patients often require assistance in maintaining a patent airway, and positive pressure ventilation may be required because of depressed spontaneous ventilation or drug-induced depression of neuromuscular function. Cardiovascular function may be impaired.

Local anesthesia–the elimination of sensation, especially pain, in one part of the body by the topical application or regional injection of a drug. Minimal sedation–a minimally depressed level of consciousness, produced by a pharmacological method, that retains the patient's ability to independently and continuously maintain an airway and respond normally to tactile stimulation and verbal command. Although cognitive function and coordination may be modestly impaired, ventilatory and cardiovascular functions are unaffected. Moderate sedation–a drug-induced depression of consciousness during which patients respond purposefully to verbal commands, either alone or accompanied by light tactile stimulation. No interventions are required to maintain a patent airway, and spontaneous ventilation is adequate. Cardiovascular function is usually maintained.

Routes of Administration enteral–any technique of administration in which the agent is absorbed through the gastrointestinal (GI) tract or oral mucosa (i.e., oral, rectal, sublingual). Inhalation–a technique of administration in which a gaseous or volatile agent is introduced into the lungs and whose primary effect is due to absorption through the gas/blood interface. Parenteral–a technique of administration in which the drug bypasses the gastrointestinal (GI) tract (i.e., intramuscular IM, intravenous IV, intranasal IN, submucosal SM, subcutaneous SC, intraosseous IO.) transdermal–a technique of administration in which the drug is administered by patch or iontophoresis through skin.

Transmucosal – a technique of administration in which the drug is administered across mucosa such as intranasal, sublingual or rectal. Anomaly: deviation from the normal anatomic structure, growth, development or function; an abnormality.
