The hypoglossia--hypodactylia syndrome. Report of 2 cases.
Two additional cases of the hypoglossia-hypodactylia syndrome are reported. The major features of this syndrome are a reduction in tongue size, micrognathia, and limb anomalies. The presence of these anomalies is essential for the diagnosis of this birth defect. The cause of the syndrome is unknown, but a number of theories have been proposed. Treatment of these cases has been directed toward improving tongue, lip, and mandibular function.

Root resorption by ameloblastomas and cysts of the jaws.
Radiographs of 122 cases of a series of nonmalignant simple jaw cysts and ameloblastomas were examined and the frequency of resorption of adjacent tooth roots compared. The ameloblastomas proved to have a root resorptive potential far greater than the cystic lesions considered. Certain statistically significant differences were observed in the root resorption related to the cystic lesions. The dentigerous cyst showed a tendency to resorb roots (55%), whereas in this study no resorption was observed in primordial cysts. These differences may aid the clinician in the preoperative differential diagnosis. It is suggested that the capacity of the dentigerous cyst for root resorption may be the result of its origin from the dental follicle, which is associated with resorption of the roots of primary teeth during normal tooth succession.
