[The method of getting the prime diagnostic factors of anterior crossbite in early permanent dentition]
OBJECTIVE:We want to select the prime diagnostic factors of anterior corssibe which cna be used to identify the dental and skeletal anterior crossbite. METHODS: From 85 anterior crossbite patients in early permanent dentistion with accurate diagnosis we selected 70 cases to get the prime diagnostic factors by using stepwise discriminant analysis. They were checked by the other 15 cases, We could assess the effects of the factors by calculating their contribution rates. RESULTS: We get six factors: CoGn,AOBO,S'-Ptm',ANB,MPPP,Ramus Angle. CONCLUSION: They include the most information we need to indentify the dental or skeletal anterior crossbite.
