Essentials of Oral Histology and Embryology: A Clinical Approach, 4e (Avery, Essentials of Oral Histology and Embryology)
"This basic science text, now in an updated fourth edition, provides a clear and comprehensive guide to understanding a complex but essential part of the dental curriculum. As such, it is aimed mainly at an undergraduate dental population but can also be used  as a postgraduate reference text...This text's real strength lies in the use of a wide variety of high-quality images, which include histology slides, micrographs, radiographs and clinical photos...A further selling point is the ability for users to access a wealth of online information including a question and image bank, presentations, web-links and interactive exercises free of charge."The British Dental Journal, July 2013
