RESUMEN
Hutchinson's incisors and Moon's molars are specific lesions of congenital syphilis. The extensive but fragmentary clinical literature on these conditions describes reduced dimensions and thin enamel in the permanent incisors and first molars, crowding and infolding of the first molar cusps, notching of the upper incisors, and apical hypoplasias of the permanent canines. A Barbados slave cemetery (ca. 1660-1820 AD) includes three individuals with these features, suggesting a frequency at birth of congenital syphilis in the population approaching 10%. These three cases show triple the frequency of all hypoplasias and more than seven times the frequency of pitting hypoplasia present in the remainder of the series. The recognizable congenital syphilis cases account for much of the remarkably high frequency of hypoplasias in the series as a whole. We infer that syphilis contributed substantially to morbidity, infant mortality, and infertility in this population. Presence or absence of congenital syphilis may account for much of the variability in health and mortality seen among nineteenth century African-American populations.
PIP: 2 anthropologists examined the teeth of 104 slaves buried between 1660 and 1820 who had worked on Newton Plantation in Barbados, West Indies, and were excavated between 1971 and 1973 to look for obvious evidence of congenital syphilis. 84 bodies still possessed either incisors or first molars in good enough shape for the anthropologists to examine. 3 young adult or adolescent slaves had dental lesions indicating congenital syphilis (Hutchinson's incisors and/or Moon's molars). These 3 cases had a frequency of all hypoplasias 3 times that of the remaining slaves and a frequency of 7.5 times of pitting hypoplasia. The frequency of congenital syphilis was at least 3%. Literature data indicate that congenital syphilis features are evident in 33% of cases; therefore, the frequency of congenital syphilis at birth was likely to be around 10%. None of the cases were less than 5 years old. Further, wear and cavity-related tooth loss eliminated evidence of congenital syphilis in people at least 30 years old. The anthropologists gathered that syphilis was responsible for sizeable illness, infant deaths, and infertility among these slaves. They also reviewed 3 dental studies of 3 US African American cemeteries. The individuals in 2 cemeteries had no evidence of congenital syphilis and were in relatively good health, while individuals from the postslavery period had evidence of congenital syphilis (5%). The researchers suggested that presence of absence of congenital syphilis may explain much of the variance in mortality and health noted among 19th century African American populations.
