dontodysplasia is a rare condition, of unknown cause, seen in children.

CASE REPORT A Negro girl, aged 2 years 10 months, was brought to our clinic with a chief complaint. of “sore gums.” The patient had a full-term natural birth with no complications except that a proptosis of the left eye was noted. At the age of 5 months she entered the hospital for treatment of the above condition. Four diagnostic skull films were taken prior to the operation. A left orbitotomy was performed, and a large cyst was removed from the posterolatera.1 orbit. It was adherent to the left lateral rectus muscle and had a “watery-oily” content,. Thr: laboratory test results were within normal limits. The mother claimed that the lower incisors erupted into the oral cavity when the chiltl was 6 months of age and that they were white in color. She said that all the teeth mere white on eruption and turned brown only after being in the mouth for at least a mont,h. All of the mandibular teeth except the deciduous lower second molars were grossly carious. ThlL affected teeth appeared to be normal in shape but had extremely hypoplastic enamel. Radiologically, the maxillary teeth appeared normal, but the mandibular teeth except for the deciduous right second molar and the permanent right first molar appeared as radiolucencies surrounded by slightly calcific tissue. Calcification was greatly reduced, The pull) chambers and root canals seemed to be greatly enlarged, with a thin band of dent,ine 2nd a thin band of enamel. The roots were very short and blunted.
