Oral and facial inclusion cysts in newborns.

This study assessed the frequency of milia, alveolar and palatal cysts prevalence in newborns as well as the time for complete involution of the most common reported inclusion cyst. Milia, alveolar and palatal cysts were observed in respectively, 31.4%, 28.2% and 78.8% of the newborns. Those that presented milia were 1.2 times more likely to present alveolar cysts. Mean time for complete involution of palatal cysts was 4.5 weeks.
