ABSTRACT

The thumb-sucking habit is acquired in infancy, but if it persists beyond preschool age, it can have deleterious effects on facial growth, oral function, occlusal relationship, and aesthetics, leading to dental and skeletal deformities. This paper presents a clinical case history of using nonpunitive reminder therapy to intercept the thumb-sucking habits of an 8-year-old child with epilepsy. A modified Bluegrass appliance was used along with the positive reinforcement. The modified Bluegrass appliance utilized an acrylic roller and was very comfortable for the patient; it was also successful in eliminating the habit within a short period of time.
