Acid erosion (corrosion): Case reported

D.D.S. Marcelo Alberto Iruretagoyena

A 60-year-old female patient who, upon clinical inspection, observed loss of enamel due to acid erosion in the anterior-superior teeth. During the interrogation the patient tells that he ingests large quantities of lemon and natural oranges. This dietary habit causes acid erosion due to the citric acid content contained in these fruits.
Note in the lower images the extensive deterioration of the enamel, which leads in some places to the exposure of the dentin. As the process is gradual, the patient does not have painful symptoms to the thermal stimulus.
This type of injury is classified on a scale of mild, moderate and severe, as serious and should be treated with aesthetic coatings based on resin or porcelain. Failure to treat these injuries can lead to tooth decay with the loss of teeth. Another action to consider is the possibility of a change in diet, based on the decrease in the frequency of lemon and orange intake.

Observe how the dental structure has been lost in 13, 12 and in 11 a veneer in composite resin where the superficial cav edge of the same has deteriorated. In 23 the same pattern of dental demineralization

Definition of acid erosion: The erosion also called corrosion, is defined as the loss of the structure of the teeth by chemical action in the presence of continuous demineralizing agents, especially acids and does not involve the presence of bacteria.
