Abstract
Disordered embryonic development can lead to a wide range of developmental disorders in the oral cavity. Many of these are related to the disordered or incomplete fusion of separate developmental lines of the face. Whilst some are relatively common and often trivial, others are rare and can be more serious. For example, small developmental cysts are commonly found on the palate of newborns. It is believed, by some, that these are the result of epithelial entrapment in the median palatal raphe. Others hold that they are the result of epithelial remnants of developing salivary glands. These cysts are termed Epstein’s pearls when they occur in the midline of the palate and Bohn’s nodules when they occur scattered on the palate. Ectopic sebaceous glands are common and termed Fordyce’s granules. They can be found in 80% of the population and hence are not generally considered a true developmental abnormality but rather a variant of normal development .
