Summary

To increase understanding of the terminology used in oral health care, a glossary has been provided as a handout. The goal of this module is to increase understanding around the terminology of oral health care in general as well as that specific to PLWHA. Many of these terms are referenced throughout the curriculum and thus, this module is a useful reference tool to maximize comprehension and, utility as well as improve overall oral health literacy for clinic staff, and improve communication between medical providers and dental clinicians. Where applicable, this handout can be modified and provided to patients to include those terms used in patient-provider conversations.

Materials Needed:

Copies of the glossary should be printed for distribution to each person.

HANDOUT

A glossary handout of common oral health terminology begins on the following page to facilitate printing and photocopying.

Module 4: Glossary of Oral Health Terminology

Unless otherwise indicated, the definitions below are from the American Dental Association (ADA). The ADA is a national standards development organization for oral health. Additional oral health terminology is available at: www.ada.org/glossaryforprofessionals.aspx.

A

abscess, acute periradicular or acute apical: An inflammatory reaction to pulpal infection and necrosis characterized by rapid onset, spontaneous pain, tenderness of the tooth to pressure, pus formation and eventual swelling of associated tissues. May also be known as acute periapical abscess, acute alveolar abscess, dentoalveolar abscess, phoenix abscess, recrudescent abscess, and secondary apical abscess.

abscess, chronic periradicular or chronic periapical: An inflammatory reaction to pulpal infection and necrosis characterized by gradual onset, little or no discomfort and the intermittent discharge of pus through an associated sinus tract. May also be known as chronic alveolar abscess, chronic apical abscess, chronic dentoalveolar abscess, suppurative apical periodontitis, and suppurative periradiucular periodontitis.

abutment: A tooth or implant fixture used as a support for a prosthesis.

abutment crown: Artificial crown also serving for the retention or support of a dental prosthesis.

accession: Addition of a test specimen, previously collected by a health care provider, to a laboratory specimen collection; recording of essential specimen identification data in a laboratory-maintained file in chronological order of laboratory specimen acquisition; assignment to the specimen of an identification code.

acid etching: Use of an acidic chemical substance to prepare the tooth enamel and/or dentin surface to provide retention for bonding.

adhesion: State in which two surfaces are held together by chemical or physical forces or both with or without the aid of an adhesive. Adhesion is one aspect of bonding.

adhesive: Any substance that joins or creates close adherence of two or more surfaces. Intermediate material that causes two materials to adhere to each other.
