NDAEB Patient Records and Charting 2

Question 1

When charting a tooth that has been extracted and is no longer present in the patient's mouth, what symbol is typically used in the geometric charting system?

Accepted Answer

An X drawn through the tooth symbol

Answer

In the geometric charting system commonly used in Canadian dental offices, a large X drawn through the tooth symbol indicates that the tooth has been extracted or is missing.

Question 2

According to Canadian dental record-keeping standards, how long must patient dental records be retained after the patient's last visit?

Accepted Answer

10 years from the date of last entry, or until the patient reaches the age of majority plus 10 years for minors

Answer

Most Canadian provincial dental regulations require records to be retained for 10 years from the date of the last entry, with additional requirements for minor patients whose records must be kept until 10 years after they reach the age of majority.

Question 3

In the FDI (Fédération Dentaire Internationale) tooth numbering system used in Canadian dental practice, what number designates the permanent maxillary right canine?

Accepted Answer

13

Answer

In the FDI system, the first digit represents the quadrant (1 = permanent upper right) and the second digit represents the tooth position (3 = canine). Therefore, the permanent maxillary right canine is tooth 13.

Question 4

What information must be recorded in the patient's chart immediately following the administration of local anaesthesia?

Accepted Answer

The type of anaesthetic, amount administered, lot number, expiration date, injection site, and any adverse reactions

Answer

Complete anaesthesia documentation includes the specific agent, vasoconstrictor type and concentration, number of cartridges, lot number, expiration date, injection technique/site, and any adverse reactions. This is both a legal requirement and essential for patient safety.

Question 5

When updating a patient's medical history form, the patient reports they have started taking warfarin (Coumadin). Why is this medication particularly significant for dental charting and treatment planning?

Accepted Answer

It is an anticoagulant that significantly increases bleeding risk during dental procedures

Answer

Warfarin is an anticoagulant (blood thinner) that significantly increases the risk of prolonged bleeding during invasive dental procedures. This must be prominently flagged in the chart and communicated to the dentist before any treatment.
