Dental Abbreviations, Symbols and Acronyms
Introduction:
Abbreviations, acronyms and symbols are often used in dental charting or in dental publications
as a convenience. The Council on Dental Practice (CDP) maintains this listing of dental
abbreviations, symbols and acronyms in an effort to give uniformity for authors, educators,
practitioners, oral health care students and others who may have a need to use or know common
dental and dental-related abbreviations, symbols and acronyms.
You will notice that there may be more than one meaning for an abbreviation and/or acronym, or
more than one common way to abbreviate a term. The lists provided here reflect current usage
as reported to the Council on Dental Practice. It is always important to keep in mind the context
of the entry when using or interpreting an abbreviation or acronym.
The Council recommends that dentists select their own approved list of abbreviations, symbols
and/or acronyms for their offices. This list should be made part of your office policies so that all
team members use uniform terminology. A form is provided for this purpose in this publication.
Dentists may wish to consider making this form available when complying with a patient’s or other
lawful request for records.
Acronyms, abbreviations and symbols selected should have single meanings in your office.
Dentists should avoid using abbreviations, symbols or acronyms that are obscure. Unique
abbreviations, symbols or acronyms may not be understood by others and may cause a variety of
problems in both a clinical and legal setting. If there is any doubt about the understanding of an
abbreviation, symbol or acronym, it should not be used. Dentists are advised to consult with their
own legal counsel, professional liability insurers or risk management representatives for specific
advice.
Abbreviations or acronyms should not be used on patient informed consent forms. Dentists are
also advised to refrain from using abbreviations when writing prescriptions for patients. While
these may be commonly used in charting, prescriptions given to patients should be completely
legible and no abbreviations should be used. Recommendations from the National Coordinating
Council for Medication Error Reporting and Prevention (NCC MERP) are included in this text.
Finally, this listing is not complete. Comments and suggestions from readers regarding additions
or deletions to future editions of this publication are welcome. Please submit your comments or

COUNCIL RECOMMENDATION
Recommendations to Enhance Accuracy of Prescription Writing
Adopted Sept. 4, 1996
Revised June 2, 2005
Personnel to whom this applies: Prescribers; Nursing or Pharmacy staff (who transcribe verbal
prescription orders or rewrite transfer or admission orders when entering or leaving a health
care facility); Health care administrators/managers.
Technology plays an important role in the delivery of healthcare. Utilize technology, as
appropriate, but evaluate its effectiveness on an ongoing basis. While technology can reduce
medication errors and enhance patient safety, it also has the potential to cause new types of
unintentional errors.
The Council recommends:
1. ...all prescription documents be legible. Verbal orders should be minimized. (See the
Council's Recommendations to Reduce Medication Errors Associated with Verbal
Medication Orders and Prescriptions)
2. ...prescription orders include a brief notation of purpose (e.g., for cough), unless
considered inappropriate by the prescriber. Notation of purpose can help further
assure that the proper medication is dispensed and creates an extra safety check in
the process of prescribing and dispensing a medication. The Council does recognize,
however, that certain medications and disease states may warrant maintaining
confidentiality.
3. ...all prescription orders be written in the metric system except for therapies that use
standard units such as insulin, vitamins, etc. Units should be spelled out rather than
writing "U." The change to the use of the metric system from the archaic apothecary
and avoirdupois systems will help avoid misinterpretations of these abbreviations and
symbols, and miscalculations when converting to metric, which is used in product
labeling and package inserts.
4. ...prescribers include age and, when appropriate, weight of the patient on the
prescription or medication order. The most common errors in dosage result in
pediatric and geriatric populations. The age (and weight) of a patient can help

dispensing health care professionals in their double check of the appropriate drug and
dose.
5. ...medication orders include drug name, exact metric weight or concentration, and
dosage form. Strength should be expressed in metric amounts and concentration
should be specified. Each order for a medication should be complete. The pharmacist
should check with the prescriber if any information is missing or questionable.
6. ...a leading zero always precede a decimal expression of less than one. A terminal or
trailing zero should never be used after a decimal. Ten-fold errors in drug strength
and dosage have occurred with decimals due to the use of a trailing zero or the
absence of a leading zero.
7. ...prescribers avoid the use of abbreviations including those for drug names (e.g.,
MOM, HCTZ) and Latin directions for use. The abbreviations in the chart below are
found to be particularly dangerous because they have been consistently
misunderstood and therefore, should never be used. The Council reviewed the uses
for many abbreviations and determined that any attempt at standardization of
abbreviations would not adequately address the problems of illegibility and misuse.
Abbreviation
Intended meaning
U
Units
Mistaken as a zero or a four (4) resulting in
overdose. Also mistaken for "cc" (cubic
centimeters) when poorly written.
μg
Micrograms
Mistaken for "mg" (milligrams) resulting in
an overdose.
Q.D.
The period after the "Q" has sometimes
Latin abbreviation been mistaken for an " I, " and the drug has
been given "QID" (four times daily) rather
for every day
than daily.
Q.O.D.
Misinterpreted as "QD" (daily) or "QID" (four
Latin abbreviation
times daily). If the "O" is poorly written, it
for every other day
looks like a period or "I."
SC or SQ
Subcutaneous
Mistaken as "SL" (sublingual) when poorly
written.
TIW
Three times a week
Misinterpreted as "three times a day" or
"twice a week."
D/C
HS
Cc
Discharge;
discontinue
Common Error
Patient's
medications
have
been
prematurely discontinued when D/C,
also
(intended to mean "discharge") was
misinterpreted as "discontinue," because it
was followed by a list of drugs.
Half strength
Misinterpreted as the Latin abbreviation
"HS" (hour of sleep).
Cubic centimeters
Mistaken as "U" (units) when poorly written.

AU, AS, AD
Latin abbreviation Misinterpreted as the Latin abbreviation
for both ears; left "OU" (both eyes); "OS" (left eye); "OD"
ear; right ear
(right eye)
IU
International Unit
MS,
MSO4, Confused
MgSO4
another
for
Mistaken as IV (intravenous) or 10(ten)
one Can mean morphine sulfate or magnesium
sulfate
8. ...prescribers avoid vague instructions such as "Take as directed" or "Take/Use as
needed" as the sole direction for use. Specific directions to the patient are useful to
help reinforce proper medication use, particularly if therapy is to be interrupted for a
time. Clear directions are a necessity for the dispenser to: (1) check the proper dose
for the patient; and, (2) enable effective patient counseling.
In summary, the Council recommends:
Don't Wait . . . Automate!
When In Doubt, Write It Out!
When In Doubt, Check It Out!
Lead, Don't Trail
