Course Description

Participants of this course will review the composition of saliva, as well as the histology, anatomy, and physiology of the human salivary glands. This course offers information on the tubarial salivary gland, intending to provide new insight into emerging science and evidence for this previously unidentified anatomical feature of the head and neck. Specific attention is given to the areas of biochemistry, buffering capacity, and pathology of salivary glands. This course is designed to assist clinicians in obtaining a better understanding of saliva and salivary glands, and their role in oral health, while also providing decision-making information regarding patient care.
