A new patient presents requesting evaluation of tooth #8, which has caries. No previous dental radiographs are available. What type of examination should be performed?

Correct answer: D. Comprehensive oral examination

• A. A periodontal-only examination is a specialized exam and does not substitute for the required comprehensive evaluation of a new patient.
• B. A limited/problem-focused exam (D0140) is for established patients or emergency visits addressing a specific complaint. A new patient with no records requires comprehensive evaluation.
• C. Periodic examination (D0120) is for existing patients returning for routine recall — not appropriate for a new patient.
• D. CORRECT. A comprehensive oral examination (D0150) is indicated for new patients. It includes evaluation of all hard and soft tissues, periodontal status, occlusion, TMJ, and a complete medical/dental history. Even though the patient's chief complaint is one tooth, a new patient requires a full comprehensive assessment before any treatment.
