On the terminology of mandibular prognathism: Class III malocclusion

theory. Numerous studies of regular transmission through several generations of prognathism with anterior positioning of the mandibular incisors and even distribution between the sexes indicate an autosomal dominant gene. However, the dominant hereditary sequence may be stimulated. Recent research on eleven genealogic groups, whose probands bore only microsymptoms and questionable ones at that, have shown that in most cases patients with clear symptoms of prognathism can be found sporadically or among siblings only. Transmission over several generations is an exception. These results also support the assumption that prognathism of the frequent type is based on polygenic inheritance or a multifactorial system, respectively. Special types with simple dominant patterns are possible. however. J. A. Salzmann

Classifications of anomalies are discussed which, in Anglo-Saxon countries, are commonly called mandibulur prognathism or mandibular protrusion and, in Germany, Progenie. This term was introduced in I868 by L. Meyer, a neurologist of Gottingen. The different concepts are discussed, with emphasis on the need to avoid using different terms for genetically and structurally similar anomalies. J. A. Salzmann

Lollipops

(News Item)

Y, I979

Michael Jacobsen, director of Science in the Public Interest, brought the full force of his wrath down on the American Cancer Society (ACS) when he discovered that it was giving lollipops to children as a fund-raising gimmick. He sent a protest to the ACS and released it to the press. Jacobsen was upset, first, because the ACS was giving out hard candy (bad for the teeth) and, second, because some of the lollipops were red, containing red dye No. 40, an additive which Jacobsen suspects of being a carcinogen. The Food and Drug Administration is now engaged in a review to find out whether the dye’s safety approval should be revoked but has not reached any conclusion. J. A. Salzmarzn
