Abstract

Inclusion cysts of transient nature during the neonatal period are developmental lesions, which are seen in the oral cavity of the newborn infant. These lesions are classified into three subtypes according to their localizations. When noticed by the anxious parents on the gingival surfaces, they are often mistaken for natal teeth, which lead to seeking medical attention. Herein, we describe a newborn infant with Bohn’s nodules to increase the awareness of the physicians to this benign, self-limiting lesion.

Intraoral lesions Newborn
A 7-day-old, 3,550-g male infant who was born at 40 weeks gestational age was brought to the neonatology outpatient clinic due to two small, white-colored, round-shaped protuberances on the maxillary gingival surface, which were assumed to be dental edges by the caregivers (Fig. 1). The lesion was firm and not tender to palpation. There was no erythema around it, and the physical examination was otherwise unremarkable.

Small, firm, white-colored lesions on the maxillary gingival surface consistent with Bohn’s nodules

Inclusion cysts of transient nature during the neonatal period are developmental lesions, which are seen in the oral cavity of the newborn infant. These lesions are classified into three subtypes according to their localizations. They can be seen either on the gingiva (Bohn’s nodules), along the midline of the palate (Epstein’s pearls) or on ingrowth ectodermal laminar surfaces of the oral cavity (dental lamina cysts). When noticed by the anxious parents on the gingival surfaces, they are often mistaken for natal teeth, which lead to seeking medical attention. Physicians should be able to recognize these lesions, explain its benign, self-limiting nature to the caregivers, and reassure them to avoid unnecessary medical or surgical intervention. The cysts usually disappear spontaneously between 1 and 2 weeks of birth [1, 2].
