Connecticut is among the best organized of all of the states in its approach to the problem of cancer. The attack on cancer must be total. Every one of the healing professions is concerned in the earliest possible detection of the symptoms of this disease. The handbook here reviewed is a product of a special committee and is circulated through the Connecticut State Department of Health and the Connecticut State Dental Association. It is magnificently illustrated with black and white and colored illustrations which portray graphically the conditions for which the dentist should be continually observant.
