title: [Evaluation of dental diseases and clinical therapy of children in 1990, 1995].
abstract: OBJECTIVE
  To study changes in patterns of children's dental diseases and their dental care improvements.
  
  
  METHODS
  The survey was conducted on the basis of selection of 1,066 and 1,016 medical records of January, April, July and October of 1990 and 1995, respectively, from the complete hospital file.
  
  
  RESULTS
  There was a distinct increase in pain and swelling as chief complaint, in regular check and in occlusal discrepancies, all with a significant difference of P < 0.01. No significant difference was found in caries and dental injury in both years. However in either of the two years caries remained the major dental disease. In dental treatment a significant difference (P < 0.01) indicated an increase in interception orthodontics and preventive treatment and a decrease in pulpal treatment. There was no remarkable differences in decay filling and extraction of teeth.
  
  
  CONCLUSIONS
  The survey signified changes in patterns of children's dental diseases and evident improvement in children's dental therapy.
