This application demonstrates how a large database (500,000 randomly generated mixed (MISSING AND UNIDENTIFIED) records) of dental charts can be quickly searched for possible matches.
A process called DENTAL TREATMENT SIGNIFICANCE RANKING (DTSR) is used to rank returns.
Click on 'NEW RECORD' below to prepare a new entry.

Click on 'LOAD EXAMPLE' to have program select a random entry from the 500,000 record database.

If the selected record is 'UNIDENTIFIED'(POST MORTEM - FOUND), the search will be altered to "MISSING'
The year of the search will be changed to a random year before (or same as) the year the selected subject was found.
Any missing post mortem (/) tooth codes will be changed to various valid combinations of codes.
To simulate coding errors, a random number of codes representing 'irrational changes' will be entered into the search.

If the selected record is "MISSING" (ANTE MORTEM), the search will be altered to 'UNIDENTIFIED' (POST MORTEM - FOUND)
The year of the search will be changed to a random year after (or the same as) the year the selected subject was last seen.
To simulate 'rational changes' (subsequent dental treatment) a random number of codes representing 'rational changes' will be entered into the search.
To simulate coding errors, a random number of codes representing 'irrational changes' will be entered into the search.
Select 'SEARCH RECORD' to run the search.

Set ANTE MORTEM or POST MORTEM (default)
Select the tooth Numbering System you are comfortable with
Carefully enter codes for every one of the 32 teeth above from the chart in your possession.
(You can tab from 1 - 32 box turns red when in focus)
The boxes will only accept Primary Code Letters V M O D F L X C R and B
V is the default code for each tooth.
You can also enter or delete codes in the graphical interface.
There are five surface blocks, and four corner blocks (pass mouse over each one for description of the function.)
For O.O, just enter O.
The program will automatically order the codes to comply with NCIC protocol.
Secondary Codes R (endontics) and C (crown, inlay etc.) Cannot be entered alone and must follow Primary Dental Codes
NOTE: If you enter B, it will be changed to F as the meaning is the same.

Primary Dental Codes - One or more codes must be entered for each tooth.

Code	Code Description
V	Virgin. Default code for Missing Persons. Tooth is present or assumed to be present and unrestored. This includes unerupted teeth, such as wisdom or deciduous teeth. If no information is available for a particular tooth, this code should be used as it is assumed that all teeth are present (erupted or unerupted) and unrestored when they develop. This code is also used when a tooth has been restored but it is impossible to determine which surface has been restored (most common example of this is the location of a pit type filling on molars when it is impossible to determine whether the filling is on the facial or lingual surface). Note: This code is used differently when coding dental characteristics for Unidentifi ed Persons.
/	A portion of the tooth is remaining and treatment has probably been accomplished on the tooth but it is impossible to determine which surfaces have been restored. This code is most frequently used when a tooth has had an endodontic procedure accomplished and the clinical crown has fractured off. This code is seldom used in coding missing persons dental information. Note: For Unidentified Persons, this code means Missing Post Mortem.
X	Missing. Tooth has been extracted or is congenitally missing.
M	Mesial surface of the tooth has been restored.
O	Occlusal or Incisal surface of the tooth has been restored.
D	Distal surface of the tooth has been restored.
F	Facial or Buccal surface of the tooth has been restored.
L	Lingual surface of the tooth has been restored.

Secondary Dental Codes - Cannot be used independently. Must be used in conjunction with Primary codes.

Code	Code Description
C	Any laboratory processed restoration including crowns, inlays, onlays, and veneers. This code also includes prefabricated restorations such as stainless steel crowns, metal and acrylic temporary crowns, and porcelain processed veneers.
R	Root canal. Evidence is available to establish that an endodontic procedure has been started or completed.
