Abstract

Introduction: Decreasing pain elicited by injections in children results in patient comfort during dental procedures and produces a positive experience towards dental procedures. The aim of the present study was to compare the effect of Dentipatch and 20% benzocaine gel in decreasing injection pain in children referring to Isfahan Faculty of Dentistry. Materials and Methods: Simple sampling method was used in the present clinical trial to select fifty-four 9-12 year-old children (24 males and 30 females). The injection site was dried with air spray for 5 seconds; then Dentipatch was placed by a dentist on the palate for 12 minutes at a distance of 5-10 mm from the gingival margin. A total of 1.8 mL of 2% lidocaine was injected; 10 minutes after the injection the same procedure was repeated on the contra-lateral side with the use of benzocaine gel. Data was collected and analyzed with pained t-test and Wilcoxon test using CPS and VAS scales (α = 0.05). Results: Means of CPS in non-anxious children in the benzocaine and Dentipatch groups were 6.4 and 5.8, respectively, with no statistically significant differences (p value = 0.081). Means of VAS in non-anxious children in the benzocaine and Dentipatch groups were 39.2 and 32.5, respectively, with no statistically significant differences (p value = 0.068). Conclusion: Under the limits of the present study, it was concluded that there is no difference between the two methods regarding children’s reaction. Further evaluations are recommended with different application times, especially with the new Dentipatech method.   Key words: Dentipatch, Infiltration injection, Local anesthesia, Palate.
