Generally, well controlled or moderately well controlled diabetic patients are not prone to infections to non invasive scaling procedures. A routine oral prophylaxis is advised. Antibiotics should be given for a diabetic patient for the same procedures that would be done in a non diabetic patient. This includes any invasive surgical procedures. Poorly controlled diabetics ( fasting blood glucose above 250 mg/dL) should be referred for better control of sugar levels for non-emergency procedures. In case of emergency, in poorly controlled patients, prophylactic antibiotics is prudent.
