DISCUSSION The results of this study are consistent with other studies in which oral sucrose retention is determined by instrumental analyses using either the hydrogen peroxide electrode method or HPLC method (Sreebny et al., 198.5), indicating the value of the indicator strips investigated. Dawes (1983) found that the most significant factor influencing sugar clearance is the unstimulated salivary flow rate. He proposed a theoretical equation for sugar retention as a function of unstimulated salivary flow rate. InFig. 1, clearance time is plotted against the reciprocal of the unstimulated salivary flow rate to demonstrate that the relationship between them conforms to the equation proposed by Dawes (1983). Although clearance time fluctuates (Ueda and Nakao, 1986), the linear regression remains statistically significant (P < 0.01). A similar plot comparing the clearance time and stimulated salivary flow rate is illustrated in Fig. 2-no correlation is apparent, again consistent with Dawes’ theory (1983). It is suggested that the sucrose indicator strips investigated are simple to use, effective and merit further investigation.

The third edition of this well-established textbook has been extensively revised to take note of the many changes in dental practice and terminology in the 7 years since its predecessor and, in general, it continues to fulfil a defined need more than adequately. However, consideration will have to be given to the impact of the recently agreed National Vocational Qualification, Occupational Standards of Dental Surgery Assistants (1990). on their courses and textbooks of the kind. Similarly, the chapter on Dental Radiography needs to take account of the lonising Radiation Regulations (1988): it is more important, for instance, that they know how to store E-speed dental film than the angles for periapical radiography. The dental needs of patients with the AIDS (and AIDS-related) complex are not the same as for those who are only HIVpositive. P. Hirschmann

Brief Notice: Contemporary Dental Hygiene Practice, Vol. 2. P. S. Phagan-Schostok and K. L. Maloney. Pp. 120. 1989. New Malden, Quintessence. Softback, f22.00 This is the sequel to the first volume published in 1988 (and reviewed in this journal, 1989, 17, 283), and covers those expanded duties, which, under current regulations, are not permissible in Great Britain, devoting a chapter to each. There is a large section on radiographic techniques, including interpretation. The second chapter covers the application of rubber dam, placement of temporary crowns and finishing of amalgam restorations. Control of pain and anxiety in dentistry describes administration of local anaesthesia in depth with appropriate laboratory exercises and also explains recent developments in electrically energized devices for pain control. While not of immediate relevance, this book would repay study by those concerned with the future of dental auxiliaries. S. L. Noble
