Drawing Oral histology diagrams are perhaps the most challenging task for undergraduate students. having seen the difficulty my students have experienced through the last 20 years I have decided to draw and post the diagrams usually required. Those who have worked with me or were taught by me know that I am not a very artistic person. I have always relied more on the science than art of dentistry and its subjects. As such these diagrams only aim to be scientifically accurate and not aesthetically perfect.
Dear students , I do hope the diagrams will ease the burden of drawing the diagrams and help you understand the subject better. I plan to post one diagram at a time so wait for the rest. Please leave your comments and let me know if you find the diagram helpful.
Happy learning

TOOTH DEVELOPMENT- BUD STAGE
A- Oral Epithelium consisting of stratified Squamous Epithelium
B - Dental Lamina- a band like thickening of the oral epithelium along each future dental arch that grows into the ectomesenchyme.
C- Vestibular lamina- another band of epithelium that develops buccal or labial to the dental lamina. It's cells multiply rapidly and are lost in the center, hollowing out the band and forming the future vestibule.
E- Tooth Bud- The round or ovoid swellings seen at ten sites along each dental lamina,
1- Low columnar basal cells.
2- Polygonal cells
3- Ectomesenchymal condensation (around the epithelial proliferation)
D- Developing mandible
