title: [Correlation analysis on the malocclusion and articulation of skeletal angle III malocclusion in mixed dentition].
abstract: OBJECTIVE
  To investigate the effects of skeletal Class III malocclusion in mixed dentition on speech articulation and to look for which factors lead to the speech errors.
  
  
  METHODS
  Thirty-eight children with skeletal Angle Ill malocclusion in mixed dentition were selected as a sample group and 40 children with normal occlusion in mixed dentition as a control group. Two phoneticians evaluated their articulations and wrote down error phonemes respectively. The correlation analysis was undertaken between the number of errors and the measurements of patients' cephalometry.
  
  
  RESULTS
  The number of errors were correlated significantly with overbite, UI-LI, OBJ (OB+OJ) and TD-PW.
  
  
  CONCLUSIONS
  There is articulatory malfunction in the majority of skeletal Angle III malocclusion patients in mixed dentition. Articulatory malfunction is related to the position of incisors and the tongue.
