Clinical Practice & Review
Integrating Anatomy, Technique, and Mounting
🧐 How to Use This Review
This module simulates the “Radiographic Mounting and Identification” portion of the DANB exam. Below are the three critical mental checks you must perform for every image you see on the test.
Step 1: The “Which Arch?” Check
Before you identify a tooth, you must identify the arch. Look for these dead giveaways:
| If you see… | It MUST be… |
|---|---|
| Three roots on a molar | Maxillary |
| The Maxillary Sinus (Dark cavity) | Maxillary |
| Two roots on a molar | Mandibular |
| The Mental Foramen (Dark spot near premolars) | Mandibular |
Step 2: The “Diagnostic Quality” Check
The exam will show you a “bad” image and ask how to fix it. Use this mental map:
Is it Overlapped?
The Fix: Change your Horizontal angulation.
Is it too long/short?
The Fix: Change your Vertical angulation.
Step 3: Labial Mounting Review
Remember the Dot! In labial mounting, the raised dot faces you. This means:
- The patient’s Right is on the Left side of the mount.
- The patient’s Left is on the Right side of the mount.
- You are viewing the images as if you are shaking hands with the patient.
