Correct answer: E — Local analgesic and anti-inflammatory treatment for painful oral conditions
Benzydamine hydrochloride is a locally acting analgesic and anti-inflammatory medicine used as an oral rinse or oromucosal spray. In dentistry, it provides symptomatic relief from painful inflammatory oral conditions, including aphthous ulceration, and may be used following dental operations. Therefore, E is correct. Although benzydamine can produce transient local numbness, it is not an injectable local anaesthetic, so D is incorrect. It has no therapeutic role as an antibacterial or antifungal agent, excluding B and C, and it does not contain fluoride or prevent dental caries, excluding E. It is primarily a symptomatic treatment and does not treat the underlying cause of an oral infection.
