RESUMO
Oral examinations were performed of 1021 newborn Swedish children, of whom 101 were re-examined after 2-3 or 4-5 months. The most common findings, registered in 74.9% of the children, were of oral mucosal cysts situated either palatally or on the alveolar ridges. The majority of the palatal cysts disappeared shortly after birth, and some alveolar cysts appeared after birth. Ankyloglossia was found in 2.5% of the children, and Fordyce spots in 1.0%. No natal teeth were found. The upper labial frenum was attached to the crest of the alveolar ridge in 76.7% of the children, palatally in 16.7% and buccally in 6.7%. The relationship of the alveolar ridges was recorded: the anterior segment of the mandibular ridge was distal to the maxillary in 99% of cases, and, posteriorly, the mandibular ridges were lingual to the maxillary in 97.6%. An open bite was found in 39.8% of the children.
