vomiting.
Bulimia Nervosa
compulsive disorder that involves periods of starvation, binging, and purging.
Signs and Symptoms of erosion
-dental caries from vomiting
-Perimolysis: erosion from vomiting mostly on the maxillary lingual surfaces. Raised
appearance of restoration margins.
Abrasion
,-V-shaped notch in the gingival portion of the facial aspect of the tooth.
-Results from forces of friction between the teeth or external objects.
-Can happen from improper brushing technique or the use of a toothpick or pipe.
Attrition
-Results from forces between the teeth.
-Wear on the incised and occlusal surfaces from grinding.
Abfraction
-Biomechanical destruction related to fatigue, flexure, and deformation of tooth structure.
-Can appear as a wedge-shaped lesion at the cervical third of the tooth.
