Pharmacology questions in the ADC written exam test applied prescribing decisions, not rote recall of drug names. This exam-level vignette tests your ability to work through clinical details and arrive at the correct management.
A 17-year-old male had endodontic treatment on his mandibular right first molar. Before treatment, the tooth had lost its mesial contact, drifted mesially, and tilted. A post-operative radiograph at 2 months shows good periapical bone healing. The temporary restoration is being replaced with a definitive core. What is the most significant long-term risk that persists despite successful endodontic treatment?
- A. Reinfection of the root canal system due to coronal leakage
- B. Vertical root fracture due to weakening of the tooth by endodontic treatment
- C. Caries on the distal surface of the adjacent second premolar due to the lost contact point
- D. Failure of the periapical radiolucency to resolve completely

The tooth drifted mesially and tilted before treatment. Even with a definitive restoration, the normal mesial contour and contact point cannot be restored. The flat mesial surface without a defined contact creates a wider contact area that is difficult to clean. The distal surface of the second premolar is now exposed to plaque accumulation and caries — and any caries that develops will affect a wider area and extend further gingivally than caries below a normal contact. There is also a risk of localised periodontitis in this area.
