Abbreviations for use in
AVDC Case Logs
Revised 10/2015
Use of these abbreviations in the Diagnosis and Procedure columns of AVDC case logs is
required for all AVDC cases logged after January 1, 2004 by applicants whose training program
started on or after January 1st 2004. From January 1, 2004, do not use other abbreviations in the
Diagnosis and Procedure columns of AVDC case log entries – additional items are to be written
out. Use by applicants whose training programs were registered prior to January 1st 2004 is
strongly recommended. Abbreviations used on AVDC case logs prior to January 1, 2004 DO
NOT have to be changed.
Changes in the approved abbreviations are made periodically, typically as a result of adoption by
AVDC of definitions proposed by the Nomenclature Committee. For example, in 2007, RL 1-5
(resorptive lesion, stage 1-5) was changed to TR and new definitions of stages 1-5 were adopted,
and MAL/AXB and MAL/PXB were changed to MAL/RXB and MAL/CXB respectively
because rostral and caudal were adopted for direction in the mouth in place of anterior and
posterior. As of April 2008, the Class of Malocclusion is to be inserted in the abbreviation of
specific tooth malocclusion (e.g. MAL/1 or 2 or 3/BN). Trainees are NOT required to change
case log entries dated prior to the notification of the change in abbreviation.
This file is available as a MS Word document, so that you may re-format it for your
convenience. On the AVDC web site, click Abbreviations - Word Format on the Information for
Registered Applicants page and then save the document on your hard drive.
You may use as many additional abbreviations on your individual patient dental charts as you
wish. Provide a list of your additional abbreviations and their definitions when you submit your
Dental Charts to AVDC for Credentials Committee review.
Tooth Identification:
Use of the Triadan tooth numbering system or anatomical description L (left), R (right), MN
(mandibular), MX (maxillary), C (canine), I1-3 (incisor), M1-3 (molar), PM1-4 (premolar) is
required in case logs as of January 1, 2012; a description of the Triadan system is available in the
Case Log section of the Information for Registered Trainees document.
Abbreviations for anatomy are left in BLACK.
Abbreviations for use in the case log Diagnosis column are shown in BLUE.
Abbreviations for use in the case log Procedure column are shown in RED.
For additional information on maintaining a case log in an AVDC training program, see the Case
Log Information page on the AVDC web site (www.AVDC.org).

Tooth resorption
TR Stage 1: Mild dental hard tissue loss (cementum or
cementum and enamel).
TR Stage 2: Moderate dental hard tissue loss (cementum or
cementum and enamel with loss of dentin that does not
extend to the pulp cavity).
TR Stage 3: Deep dental hard tissue loss (cementum or
cementum and enamel with loss of dentin that extends to
the pulp cavity); most of the tooth retains its integrity.
TR Stage 4: Extensive dental hard tissue loss (cementum or
cementum and enamel with loss of dentin that extends to
the pulp cavity); most of the tooth has lost its integrity.
(TR4a) Crown and root are equally affected;
(TR4b) Crown is more severely affected than the root;
(TR4c) Root is more severely affected than the crown.
TR Stage 5: Remnants of dental hard tissue are visible only
as irregular radiopacities, and gingival covering is complete.
