This text provides a pervasive scope of the subject material and relevant topics throughout the text's entirety. The index/glossary is equally broad-gauged and easy to locate.
The content seems to be accurate but at times communicated unconventionally. This style may appeal to some because it presents the material using different terms and may help the learner grasp the material; however, those learning specific terms and concepts for the first time may not work well.
The text's relevancy is up to current knowledge and is not likely to change as the particulars of Histology/Embryology are unchanging. However, the text is written and arranged so that information could be implemented or modified without difficulty if needed.
The text is clear but may not appeal to some looking for a more traditional form of academic writing to use for teaching. The author uses subject terminology within a colloquial, conversational writing style to engage learners, similar to the blog style of communicating.
All chapters echo one another and follow a consistent labeling format and highlight keywords or ideas, making information easy to attain. The text follows a branched design framework throughout, allowing learners to move back and forth through information by clicking onto emphasized words and terms for remedial and supplementary information to reinforce their learning. One thing to be mindful of is some of the links redirect learners to Wiki pages which can be disputable to use in education. The text also provides quality graphics for the illustration of the material.
As mentioned previously, the text follows an everyday conversational style of writing similar to blogs. Hence, the sentences and paragraphs are short, making it easier for the learner to follow and understand what they're reading. The quick quizzes at the end of the chapters are an excellent tool for engaging students in the learning and effective for highlighting gaps in understanding the material.
The material is very well-organized, appealing, and follows a logical sequence. The chapters are structured in a manner that is simple for the reader to navigate the topics.
The interface to supplemental sites seemed, for the most part, seamless. Most illustrations were of quality and clear, but a few were blurry and difficult to make out the wording. Some images download onto your computer if you click to view them on a larger scale which some readers may dislike. For instance, the following figure illustration was blurry and challenging to read and had to download for zoomed viewing: Figure 9.1: An illustration of the large number of and complicated interplay between morphogens involved in amelogenesis.

The text contained a few misspelled words and grammatical errors, but nothing too egregious that can't be overlooked.
The text does not use any language or graphics that would be deemed culturally insensitive or offensive.
I do not teach Histology/Embryology, so I can not speak as an expert on the material's content. However, as dental hygiene clinical instructor, I would recommend this book to my students for supplemental reinforcement learning. The book can help students connect concepts they may find confusing from a traditional teaching approach and textbook. I appreciated the author's communication style as it felt like you were listening to an interesting lesson rather than reading a book. If the author intended to capture the reader's attention and engage them in the learning, it was successful. This book supports active learning and would be a good interactive learning tool for an in-person or online course.
In terms of content , this text offers a wealth of wide-ranging information from start to finish. The index is easy to navigate, with both the online version and text version. read more
In terms of content , this text offers a wealth of wide-ranging information from start to finish. The index is easy to navigate, with both the online version and text version.
The information is timely, relevant and insightful and there is a plethora of examples. One downfall, is that there are terms used in the text that are not Histology/Embryology terms, which make some of the passages difficult to read. A few spelling errors here and there, as well as errors with tooth numbering systems.
Histology/Embryology information does not vary, therefore all content is relevant and will remain so.
Some terminology included words I have never heard in a dental setting, such as "remodeling unit." Sentence structure was clear and concise, some odd spacing between words in PDF version.
The online version allows the reader to hover over terms, and a definition will appear. This is beneficial to new dental hygiene students to assist in comprehension and terminology. There are also terms that can be clicked on, which will then direct you to a reference/weblink for more information. However, many of the references are Wikipedia, which is not a credible source. Any person can make changes or additions on Wikipedia.
Very brief and precise sections. Easy to navigate, very well organized. There are key takeaways, and well as brief quizzing sections that are extremely beneficial to the reader.
The book has excellent sequential topics, and it flows well. It is easy for the reader to find the topic and subtopic they are looking for
Some drawings and illustrations were clear, some were very confusing. Some of the pictures/figures had a number to reference back in the text, but then I could not find the text referencing the picture. The author used many metaphors that may make sense to him/her, but are unclear to the reader.
After reviewing the online version of the text, numerous grammatical errors were present. However, I was sometimes led to feel that the writer/contributors may use a few terms or spelling variations from other countries, which may have caused my confusion.
Since Histology and Embryology are very straight forward topics, no information could have been seen as culturally insensitive or offensive.
The cover of the book is initially shocking- seems to be a little abrupt and could deter some from attempting to read. As a dental professional, I tend to choose textbooks written by dental experts. Having a dental professional contribute may have been a nice addition to the overall feel of the book, and would have enhanced the accuracy of the dental terminology. For example: in the "About the Book" portion, the author stated "It is aimed at college students in a dental hygienist program." Dental professionals would have said "Dental Hygiene program" and not dental hygienist program.

This eBook makes use of animated images to focus on concepts in histology and embryology, as well as hyperlinks to promote non-linear reading and learning. It is aimed at college students in a dental hygienist program.
About the Contributors
Laird Sheldahl is the lead author and illustrator of this textbook. He has a Ph.D. in physiology and pharmacology. He currently teaches at Mt. Hood Community College in Gresham, OR. His Ph.D. thesis studied a morphogen (Wnt) involved in the formation of the head and neural crest cells. This morphogen is re-used during development of the teeth. To study this process in frogs (their embryos are not inside uteruses, which makes them easier to study) he did a lot of microscopy. He does not have a background in dental hygiene, and is therefore very happy to have expert collaborators.
