✍️ Sample ADC Questions & Answers
1. When is an immediate denture most indicated?
An immediate denture is fabricated before extraction and inserted at the time of anterior tooth removal so the patient is not edentulous during healing.
2. What is the purpose of a study cast (diagnostic model) in treatment planning?
Study casts provide a three-dimensional, permanent record of the patient's occlusion and arch form, enabling detailed diagnosis and treatment planning outside the clinical environment.
3. Which permanent tooth has the longest root?
The maxillary canine has the longest root of all permanent teeth, contributing to its stability and longevity.
4. The recommended casting temperature for most dental gold alloys is:
Casting at 100–150°C above the liquidus provides enough superheat to ensure the alloy remains fully fluid, fills all mold details, and allows complete compensation for heat loss during casting without premature solidification.
5. What is the Bennett movement in mandibular kinematics?
The Bennett movement is the lateral bodily shift of the mandible toward the working side during lateral excursion.
6. Which index is used to assess the severity of periodontal disease in the ADC examination context?
The Basic Periodontal Examination (BPE) uses a WHO probe to screen and record periodontal status using codes 0–4 plus an asterisk.
