To evaluate the incidence of temporomandiblar joint (TMJ) sounds of infants in the general population, three hundred and seventy four pre-school infants (196 males and 178 females) ranging in age from 1 to 6 years were investigated. TMJ sounds were classified into palpable and audible sounds according to quality, and into unilateral and bilateral sounds according to location. The relationship between TMJ sounds and age, sex, malocclusion, the number of untreated dental caries, and the number of treated teeth was analyzed.TMJ sounds were detected in 30 infants (8.0%), with no differences between the sexes. The palpable sounds (93.3%) were more frequent than the audible sounds (6.7%). The incidence of TMJ sounds increased with age (from 3 years; 1.2% to 6 years; 14.7%), and the incidence of treated teeth in infants with sounds (30.0%) was significantly higher than in infants without sounds (11.3%). According to these results, it appears that treated teeth give rise to TMJ sounds in infants.
