Effect of Pre cooling Injection Site on Pain Perception.

      Аннотация: A split mouth interventional study assessed the effect of pre cooling the injection site in patients requiring bilateral buccal infiltration prior to extraction. One half of patient’s mouth received the intervention in which the injection site was pre cooled with ice for 3 minutes along with topical Lidocaine while other half of same patient received only topical Lidocaine and served as control group. A structured proforma assessed the demographic characteristics and risk factors that influence pain percetion in patients. Mann-Whitney U tests and Wicoxon rank sum test were used for statistical analysis. The results revealed a significant difference in pain percetion between control and intervention group as assessed using both Heft-Parker Visual Analog Scale and Sound Eye Motor scale.
