ANSWER: b) Dental caries
DESCRIPTION
Herpes labialis is caused by herpes simplex virus (HSV), in
simple terms called as cold sores, which is the outbreak appearing on the lips
or around the mouth. The outbreaks usually heal within 2-3 weeks, the episodes
may occur once to thrice in a year, or may be twelve times in a year. The episodes
may decrease with time.
The factors that precipitate herpes labialis include immunosuppression,
heat of the sun; trauma of the lips, also cold precipitates the infection. Immunosuppressed
patients are more prone to viral infections so more chances of herpes labialis
precipitation. Cold producing fever and respiratory tract infection also
promotes to the cause. Dental caries has nothing to do with herpes labialis.
