Oral manifestations of a child with chronic vomiting.

Perimolysis is a type of intrinsic erosion--an irreversible dental demineralization linked to chronic regurgitation--which causes teeth to be more susceptible to dental caries. The purpose of this case report was to study a 35-month-old chronic vomiting child who visited the Department of Pediatric Dentistry in Yonsei Dental Hospital, Seoul, South Korea, for an evaluation of and treatment for the loss of tooth structure of his primary teeth. To prevent further destruction of the teeth and maintain occlusal height, all the posterior teeth were restored with stainless steel crowns and all the anterior teeth were restored with resin veneer crowns after pulpal treatment under general anesthesia. Therefore, when a child suffering from chronic vomiting visits a pediatric dental clinic, it is prudent to: (1) perform all possible dental treatment to control vomiting's adverse influences on the oral structures; and (2) refer the patient to a pediatrician to determine the cause of vomiting.
