cementifying fibroma and the ossifying fibroma of WHO terminology. Here. of course. Dr Makek is very much to be supported in his proposal to bring the two patterns or types of lesion together. Many of us are now convinced that the separation of ossifying fibroma and cementifying fibroma in the WHO monograph was undesirable, and that almost certainly the two patterns represent ends of a spectrum rather than wholly separate entities. Most of the central ‘periodontomas’ that the author defines are lesions that formerly would have been labelled as ossifying or cementifying fibromas, whilst some of his peripheral ‘periodontomas’ would have been classified as ossifying fibrous epulis or as calcifying fibroblastic granulomas. With these new ‘entities’, as with the others, only time will show whether the proposals will find general acceptance. Certainly, the proposals made by Dr Makek deserve careful consideration. for this is a thoughtful and stimulating book, well-written (save for occasional obscurities arising in the translation), welldocumented, and beautifully illustrated. Dr Makek rightly lays emphasis on the importance of distinguishing entities that differ in their behaviour, and on the importance of relating clinical. radiological and histological findings in the search for appropriate classifications. Whether or not one agrees with his conclusions and his proposals, all of the specialists concerned with the fibro-ostcocemental lesions will find much of interest and of value here. IVOR R. H. KRAMER

This relatively compact book is written for both undergraduates and dental practitioners. No fewer than 17 authors have contributed to the 25 chapters that cover a wide range of subjects. These include orthodontic and endodontic considerations, and an important contribution on ‘The Provisional Restoration’ - so often overlooked in treatment planning. I enjoyed the chapters by Dr Staffanou on hinge axis location and pantography, although in the U.K. these subjects would not normally be covered in undergraduate programmes. There is a sensible approach to tooth preparation and impression materials. It is interesting to note that reversible hydrocolloid is now no longer recommended as the only satisfactory impression material. Practical details of constructing dies, cementation, finishing and fitting of cast restorations are all to be found in this text. I am also pleased to see a chapter devoted to acid-etched resin bonded cast restorations. If one is to criticise I would complain about the quality of several illustrations, and the varying standards and repetition that is almost inevitable when several authors write about overlapping subjects. All told, this is an up-to-date and easily read book that most practitioners will find of value. It is a welcome addition to the literature. HAROLD PREISKEL

’ This soft back hand book is now in its second edition. It is not to be regarded as a major text book on the subject of oral medicine but is designed to act as a skeleton on to which material can be added from more substantial sources. Several of the chapters from the first edition have been extensively revised, re-written and expanded. New chapters on cancer and precancer, psychiatric disorders in dentistry and disorders of the tongue and taste have been added. These changes have improved both the content and the arrangement of the book but the general style has been maintained being written for the most part in note form. The clinical aspects of the subjects are emphasised and each topic is considered in a logical manner. A surprising range of material is covered in so few pages. This excellent little book is an ideal guide for both undergraduate and postgraduate students preparing for examinations and can thoroughly be recommended. BRIAN MILLAR
