Definition
Listed in this chapter are infectious diseases which are caused either by bacteria, fungi, parasites, prions or viruses. In some cases there is no involvement of the oral mucosa but there are manifestations of the diseases in the perioral areas which a dentist should be able to recognize.
Most skin infections caused by bacteria involve the gram-positive bacteria Staphylococcus and Streptococcus species.
