Paperback. Condizione: New. Print on Demand. This book is a record of dental experiments conducted on a public school class in 1910. The work was part of a larger campaign by members of the dental profession to educate the public, and especially educators, about the importance of oral hygiene. The book describes the pre-existing conditions in the mouths of the public school children of the time, and the significant improvements that were seen after the children in the experimental class received regular dental care and were educated on proper oral hygiene techniques. The details of the experiments, including the quantitative results of the psychological tests, are described in the book. This book provides a unique and valuable perspective on the state of dentistry and public health education in the early 20th century. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.
