Teeth Whitening Patient Assessment & Candidacy 2

Question 1

Which shade guide system is most commonly used in clinical practice to assess tooth color before and after whitening?

Accepted Answer

VITA Classical shade guide

Answer

The VITA Classical shade guide is the most widely adopted tool in dentistry for documenting and communicating tooth shade before and after whitening treatment.

Question 2

A patient has white spot lesions (hypocalcification) on their teeth. How does whitening typically affect these areas initially?

Accepted Answer

White spots may temporarily appear more pronounced as surrounding enamel lightens

Answer

White spot lesions often become more visible immediately after whitening because the surrounding enamel lightens faster, though the contrast may diminish over time.

Question 3

Which patient is the BEST candidate for custom at-home whitening trays?

Accepted Answer

A patient with mild extrinsic staining and no anterior restorations

Answer

A patient with mild extrinsic staining and no anterior restorations presents the simplest case, with good expected results and no color-mismatch concerns.

Question 4

What is the primary purpose of taking pre-treatment clinical photographs during patient assessment?

Accepted Answer

To document baseline tooth shade and provide before-and-after comparison

Answer

Pre-treatment photographs establish a documented baseline shade for tracking progress and provide objective before-and-after evidence for both the patient and clinical records.

Question 5

Which factor in a patient's history most significantly influences the expected whitening outcome?

Accepted Answer

The etiology (cause) of the tooth discoloration

Answer

The underlying cause of discoloration is the strongest predictor of whitening success, as intrinsic stains from medications or trauma respond very differently than extrinsic surface stains.
