Attention deficit hyperactivity disorder (ADHD) is characterized by impairing inattention, hyperactivity, and impulsivity. Stimulants, including methylphenidate (MPH) are commonly used for its management. MPH has been previously associated with both sleep bruxism (SB) and awake bruxism (AB) in high doses. Here we report emergence of SB at a low dose of sustained release MPH which was unresponsive to guanfacine but rapidly responded to buspirone (BUS).
Key words: Bruxism, Attention deficit hyperactivity disorder, Side effect, Buspirone, Methylphenidate
