OBJECTIVES: To report the @entity2720 ( @entity2720 ) kinetics and masticatory function in healthy @entity1 . DESIGN: Temporo-mandibular joint palpation and electrognathographic registrations of chewing cycles were repeated for 3 years in order to evaluate changes. SETTING: Healthy @entity1 without systemic pathologies, decayed cavities and previous dental treatment. SAMPLE AND METHODS: Electrognathographic (EGN) registration of masticatory cycles and @entity2720 palpation were carried out on 52 @entity1 (mean age: 5 years 8 months, range: 5 years 1 month, 6 years 8 months), by two university researchers, once a year for 3 consecutive years. @entity2720 palpation, differentiated @entity2720 synchronism (simultaneous bilateral opening movement) and @entity2720 asynchronism (not simultaneous bilateral opening movement), @entity2720 subluxation and click were observed. Electrognathographic registrations differentiated normal and abnormal jaw chewing cycles, and narrow and large cycles. RESULTS: Temporo-mandibular joint asynchronism was evident in 34 of 52 @entity1 in the primary dentition, in 42 of 52 @entity1 after the eruption of the first permanent molar, and in 31 of 52 @entity1 after the eruption of the permanent incisors. @entity2720 subluxation increased during the full period of observation. Three temporomandibular clicks appeared after the eruption of the permanent incisors. Altered mastication was not always associated with @entity2720 . CONCLUSIONS: In @entity1 , normal chewing cycles can coexist with occlusal discrepancies, cranio-facial growth and @entity2720 alterations.
