Correct answer: B — Reprocess it in accordance with the manufacturer’s decontamination instructions

Explanation lettering: C = shown as A · A = shown as B · E = shown as C · B = shown as E

The correct answer is A. Current SDCEP-endorsed UK guidance states that decontamination and lubrication of dental handpieces should follow the manufacturer’s instructions. This is important because handpieces differ in design and in their validated cleaning, lubrication and steam-sterilisation requirements. A surface alcohol wipe alone does not constitute validated reprocessing of a reusable handpiece (B). Fixed glutaraldehyde immersion (C), UV exposure (D), and cold chemical soaking alone (E) are not the standard UK approach for routine handpiece reprocessing and may be incompatible with the device. The key examination principle is not to assume one universal cycle for every handpiece: use the manufacturer-approved decontamination process between patients.
