Gingival cysts in infants - Gingival cysts are found on the alveolar ridges. - Formed from dental lamina fragments during tooth formation. - Harmless and do not cause discomfort. - Degenerate or rupture within 2 weeks to 5 months after birth. - Prevalence estimated to be higher than 50%.

Epsteins pearls - Palatal cysts found along the median palatal raphe. - Small white or yellow cystic vesicles (1 to 3mm in size). - Occur in 60-85% of newborns. - Filled with keratin and caused by entrapped epithelium during palate development. - Discovered by Alois Epstein in 1880.

Bohns nodules - Mucous gland cysts found at the junction of the hard and soft palate. - Derived from minor salivary glands. - 1-3mm in size and filled with keratin. - Described by Heinrich Bohn in 1886. - Sometimes confused with lateral periodontal cysts.
