Uncooperative children represent one of the leading problems in clinical pe
dodontics. The hypothesis of this study was that extroverted children revea
l greater pain tolerance, lower stress levels and anxiety in general in com
parison, to introverted ones. A total of 130 children aged 11 to 15 years w
ere studied, 55 boys and 75 girls. In the research, psychological tests wer
e performed along with the measurements of some physiological parameters an
d children's own assessment of pain intensity. The results revealed the con
nection between extroverted personality and children's behavior at the dent
ist's clinic. Pain tolerance, levels of anxiety and general pattern of beha
vior were significantly dependent on psychological control mechanisms.
