Of significant interest to orthodont&s are the chapters on control of blood circulation in oral tissues, bone healing, and the effect of trace elements on dental caries. The article by R,. M. Grainger, formerly of the University of Toronto and the University of British Columbia, Vancouver, Canada, and presently with the Department of Health, Education and Welfare, is of special concern to orthodontists. Grainger presents a “Mathematical Elucidation of Malocclusion syndromes.” He states that “the norms for the purpose of this study are taken to be the accepted norms of dental and facial form in modern man.” This reviewer knows of no accepted norms of “facial form in modern man.” On the contrary, orthodontists accept a range of variat,ions of facial form. Grainger present,s a constellation of statistical method and data that is usually terra incognita t,o t,he clinical orthodontist. He states: “The basic requirement in a s’l~ly of the interrelationships among malocclusion symptoms is to express the degree of association or correlation that exists among the items.” He adds further, however, “Because of mutilations of specimen, etc., one cannot always complete every measurement. Thus, the correlations between different pairs of characteristics cannot always be based on the full sample size. The harm caused by the missing data is very hard to judge, since one has no way of knowing how different the correlation coefficient might have been if the data had been complete.” The results are not presented by Grainger “with any belief that they are all correct.” J. A. Salxmanlz

1t is surprising bow much illformation t,llc authors have succeeded in crowding into the 51 pages of this text. Removable appliances for movement of individual teeth as an adjunct, in restorative and prosthetic dentistry are discussed. Valuable guitlcs arc provided for judging the motivation of the patient in relation to the succe.ss of treatment. ~1ldiCati~JllS are provided also concerning the limitations in treating adults.
It is understandable that lhck prxctitionr~v without basic 1il~OWlCdgC of et,iologp, diagnosis, and treatment planning will do well to consult more detailed texts. This brief handbook can be recoulmcndetl, howe:\.pr: for the practical information that it contains. J. -4, Palzrnm~z
