Previous Abnormality of Glucose Tolerance (PrevAGT)
Previous Abnormality of Glucose Tolerance (PrevAGT) A term for people who have had above-normal levels of blood glucose (sugar) when tested for diabetes in the past but who show as normal on a current test. PrevAGT used to be called either "latent diabetes" or "prediabetes."
RELATED TERMS--------------------------------------
Blood
The life-maintaining fluid which is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets; blood circulates through the body's heart, arteries, veins, and capillaries; it carries away waste matter and carbon dioxide, and brings nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues.
Glucose
The only simple carbohydrate that circulates in the bloodstream. Glucose is the primary fuel used by the brain. It can also be stored in the liver and muscles in a polymer form known as glycogen.
Diabetes
A condition in which blood glucose is not well controlled. Type I diabetics make no insulin, whereas type 2 diabetics are characterized by the overproduction of insulin, but the inability of the target cells to respond to the insulin.

PREVIOUS AND NEXT TERMS--------------------------------------
Polyphagia
Excessive hunger; may be a symptom of uncontrolled diabetes.
Polyunsaturated Fats
A type of fat that comes from vegetables.
Postprandial
Occurring after a meal. Example: Blood taken 1-2 hours after eating to see the amount of glucose in the blood would be called a postprandial blood glucose test.
Prediabetes
Traditional definition:|The stage before the development of diabetes, with normal glucose tolerance but with an increased risk of developing diabetes at some future time. Examples of increased risk might include family history of diabetes, prior diagnosis of gestational diabetes, presence of a positive antibody test for diabetes, or insulin resistance.
Preprandial
Occurring before a meal. Example: Blood taken before eating to see the amount of glucose in the blood would be called a preprandial blood glucose test. |See also: Fasting plasma glucose.

Proinsulin
The initial protein made by the beta cells of the pancreas that later is broken into several pieces. Proinsulin consists of three parts: C-Peptide and two long strands of amino acids (called the alpha and beta chains) that later become linked together to form the insulin molecule. |From every molecule of proinsulin, one molecule of insulin plus one molecule of C-Peptide are produced.
Proliferative Retinopathy
A disease of the small blood vessels of the retina of the eye. |See also: Diabetic retinopathy.
Purified Insulins
Insulins with much less of the impure proinsulin. It is thought that the use of purified insulins may help avoid or reduce some of the problems of people with diabetes such as allergic reactions.
PARTIAL DENTURES
A partial denture replaces missing teeth so that the remaining teeth, oral tissues and cheeks have support. A partial denture also will allow the patient to chew and speak properly and smile with confidence. A partial denture, like a complete denture, is made out of acrylic but unlike a denture it also uses a metal framework that attaches to the remaining teeth by use of clasps or precision attachments, which attach to crowns and give a partial denture a tighter fit and a more natural look. A partial denture is fabricated by taking impressions after the necessary work has been done on the remaining natural teeth. A partial denture will be checked for any discomfort or pressure. If a partial denture does not fit properly, a clasp or tooth can break as an end result. A partial denture must be removed before proper brushing can be accomplished. The teeth, gums and partial denture must all be cared for by the patient. Like a complete denture, regular examinations by a hygienist and dentist are important to check the supporting teeth for decay and periodontal disease and to check the continuing fit and comfort of the partial denture. See also "Dentures."
PERIODONTAL SURGERY
Periodontal surgery is usually reserved for patients who have gum problems that cannot be addressed by more conservative treatment (See "Scaling and Root Planing"). One sign of periodontal problems is having excessively large pockets between the gum and the teeth (normal pocket depth is typically 3mm or less). Patients who have excessively deep pockets usually cannot keep these pockets free of the bacteria that causes gum disease and periodontal deterioration. There are various surgical techniques that a dentist or periodontist can use to reach the affected area and treat the disease. Surgery may consist of lifting the gum away so the plaque and bacteria can be more easily removed, the roots are scaled smooth and then the gum is laid back down in a position that should make it easier to clean. Sometimes surgery involves bone grafting and the use of membranes to help stabilize and make mobile teeth firm in the bone again. If there is extensive gum loss a gingival (gum) graft may be used from tissue elsewhere in the mouth. After surgery, a periodontal pack is placed over the surgical area and the tissues are allowed to heal. Antibiotics and a mild pain reliever may also be used to help combat infection and reduce swelling. After surgery, a program of good oral hygiene and proper home care will be established for the patient to help maintain the new healthy smile. Patient recall appointments with the hygienist will also be made in shorter intervals. In recent years some periodontal surgery has been performed with the use of soft tissue lasers (See "Lasers").
