A dentist can proceed with treatment without modification or notification if they are personally suffering from which of the following conditions?

Correct answer: B. Genital herpes

• A. Active tuberculosis is transmitted by respiratory route; a dentist with active TB must be removed from patient care until non-infectious.
• B. Correct. Genital herpes is transmitted through direct mucosal/skin contact with the herpetic lesion. Because the lesion is in the genital area and not in contact with patients during dental treatment, it does not require modification of dental care or notification of patients.
• C. Active conjunctivitis (pink eye) can be caused by highly contagious pathogens (adenovirus, bacteria). The dentist should use proper PPE or defer treatment, especially because proximity to the patient's face during dental procedures poses a transmission risk.
• D. Measles is highly contagious by respiratory droplets. A dentist with active measles must not treat patients.
