The classification system for odontogenic cysts tends to be quite complex, which can create confusion for the both the clinician and pathologist alike. Traditionally, these cysts have been divided into two major groups based on whether the lesion arises de novo or develops secondary to an inflammatory process (Table 1). This discussion will update the clinical and pathologic features of several of the more interesting developmental odontogenic cysts.
