erosion

chemical process
known bacterial action

erosion is the Loss of tooth substance by [?] that DOES NOT INVOLVE [?]

1. smooth lesions occurs most frequently on the labial and buccal surfaces; may also occur on proximal surfaces

2. shallow, broad, scooped-out depression on the enamel surface adjacent to CEJ

3. generally confined to the gingival third of the labial surfaces of anterior teeth

4. may exhibit considerable variation in size and shape, usually involve several teeth

5. may progress to involve dentin thereby stimulate the formation of secondary dentin

clinical features of erosion

1. unknown in majority of cases

2. decalcification may be due to local acidosis in periodontal tissues resulting from damage due to traumatogenic occlusion

3. chronic vomiting affecting the lingual surfaces of anterior teeth resulting to loss of enamel due to gastric hydrochloric acid (common finding in patients with anorexia nervosa)

4. highly acidic carbonated beverages or lemon juice have an effect on the labial surfaces

5. habitually suck lemons and other citrus fruits

6. excessive consumption of fruit juices

7. various industries where acids are utilized, e.g. galvanizing, battery manufacture, sanitary cleanser manufacture, munitions, etc.

etiology of erosion

1. use soft toothbrush with alkaline toothpaste

2. filling
