Why are Vitamins Required for Oral Soft Tissues and Salivary Glands
|

2) Angular cheilitis or cheilosis (cracks around the corners of the mouth) and glossitis (inflammation of the tongue) are commonly associated with nutrient deficiencies |
|
The Role of the Dental Hygienist when it comes to vitamins & minerals.
|
1) Help evaluate the patient for vitamin deficiencies.
2) Be aware that water-soluble vitamin and mineral deficiencies have many oral manifestations. 3) Talk with the patient about the patient’s dietary intake or any health problems. 4) Encourage the patient to see his or her health care provider for appropriate therapy. |
