The thyroid gland and the dental practitioner.

The thyroid gland has an important function in almost every aspect of human physiology. As well, its location in the neck allows for easy evaluation by the dentist. Part I of this paper reviews the normal functions of the thyroid gland as well as systemic effects caused by abnormal function. This is supplemented by easily-acquired methods of physical examination of the thyroid gland suitable for the dental practitioner. Part II is a case report highlighting the potential adverse effects of dental treatment of a patient who had poorly controlled thyroid function following total thyroidectomy.
