Two cases of the rarely observed temporomandibular joint (TMJ) clicking in the neonate were reported.<BR>In the first case, a female baby of nine days after birth was referred to our clinic and showed bilateral TMJ clicking every time milk was taken in from her mother. On the first occasion, we could not find any gross anomaly in the face nor stomatognathic system. We followed up without any treatment. At the age of three years she had experienced TM J clicking only during yawning, and her maxillofacial and occlusal development, and teeth eruptions, masticatory function were within the normal range.<BR>This case was followed periodically for about four years. During her last visit at four years of age, the TMJ click disappeared spontaneously.<BR>The second case was a four-day old female infant, who exhibited bilateral TMJ clicking upon-taking in milk and yawning withot any physical anomaly.
