RESUMO
Examination of the early literature of dental radiology reveals that dental scientists of the time were eager to experiment with the new technology but were unaware of the dangers associated with radiation.

AIMS: This study was designed to evaluate the predictability of dental maturation patterns in non-French Canadian boys using the maturation curves developed by Demirjian & Goldstein [1]. SAMPLE: Archival cephalometric radiographs taken during a longitudinal study (1930-1960) of Caucasian Americans were re-evaluated. METHODS: Maturation of the permanent teeth on the left side of the mandible was determined according to the methods described by Demirjian & Goldstein. RESULTS: Of the 79 boys studied, 12 (15.2%) started below Demirjian's median and continued as such during the maturation process. Seven (8.9%) started within the second standard deviation above Demirjian's median and continued as such during the maturation process. The remaining 60 boys (75.9%) started below the median of Demirjian's curves at an early age. They matured at a rate that placed them above the median value at the end of the study period. The shift took place before the age of 6 years in 46 (76.6%) cases and between the ages of 6 and 8 years in another nine (15%) cases. In five of the cases which started below Demirjian's median (8.3%) the shift only took place after the age of 9 years. CONCLUSION: The shift from below median to above median value was considered an important factor in treatment planning. The data indicate that there is considerable risk for treatment planning prior to the age of 8 years. The risk is highest when the children are less than 6 years of age due to growth prediction uncertainties.

During the 19th century, dentistry was changing from a craft that was usually transmitted by a preceptor to a science that was taught in established schools. The first dental school, established in 1827 in Bainbridge, Ohio, was soon followed by a large number of proprietary and freestanding schools of dentistry. However, no matter what the status of the dental school, none would admit women. In contrast, the first woman to be admitted to a medical college graduated in 1849. The Ohio College of Dental Surgery was the first dental school to open its doors to a woman and granted a degree to Lucy Beaman Hobbs Taylor in 1866. Although the number of women to graduate from dental school increased, the number was small compared to the increase in male graduates. By 1893, about 200 women had graduated with degrees in dentistry, including a number who came from outside the United States.

The Etruscans were a group of agricultural people who evolved into an urban population of craftsmen, traders, and navigators who lived in a network of cities and dominated the area of the Mediterranean around Italy in the 8th and 9th centuries BC. What has come to be known, and is of importance in our study of the history of dentistry are a significant number of very interesting works of art which include gold dental prostheses. The Etruscan prostheses are remarkable because they used gold bands which were soldered into rings instead of the gold ones which are seen in other cultures (Egyptians, Phoenicians) of the same time.

RESUMO
At the beginning of the 19th century, the settlement of the Middle West of the United States was taking place and soon thereafter dental schools were being founded. With the establishment of dental schools, dentistry slowly evolved from a craft transmitted by a preceptor to a profession taught within established schools. Starting with Lucy Beaman Hobbs Taylor, a number of women from the Middle West entered dental schools when they were opened to them. Many active women of the Middle West became dentists and provided impetus for the profession as well as founding of the American Association of Women Dentists.
