Patients were randomly divided into the needle-free system group (filling treatment, <jats:italic>n<\/jats:italic>\u2009=\u200913; pulpotomy, <jats:italic>n<\/jats:italic>\u2009=\u200915) and dental needle method group (filling treatment, <jats:italic>n<\/jats:italic>\u2009=\u200914; pulpotomy, n\u2009=\u200914). For pulpotomy and filling treatment performed with 0.3\u2009mL anesthesia, the active ingredient of which is 2% lidocaine and 1\/80000 epinephrine. The patients\u2019 behavior before the procedure was evaluated by a pediatric dentist using the Frankl Behavior Scale. The pain intensity was assessed Immediately after injection (induction), during treatment (treatment), and at the end of the treatment (post treatment) by the Wong-Baker Faces Pain Scale.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>The median (IQR-InterQuartile Range) induction pain value was 6[3-8] and 2[0-4] in dental needle method and needle-free system respectively, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001).
