A questionnaire was utilized, which was answered by the mothers of 90 children aging three to seven years old (49 girls and 41 boys). The questionnaire inquired whether the child presented pain in the TMJ, head, ears, or in the neck region; tiredness or difficulty when chewing; if he/she used pacifier; habits like biting pens, chewing gum, teethgrinding or clenching, and biting the nails.
