Newborn rats were exposed intermittently to oxygen at high pressure (93 psig) 15 times for a period of eight days. Growth of the tooth germs was the same as that of the control rats in air at atmospheric pressure, with the exception of the enamel and dentin layers, which grew less. The width of the tooth germ of rats exposed to oxygen at atmospheric pressure increased.
