Pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage.In pediatric dentistry, the injection of local anesthesia is the most common cause of fear and expected to be painful.So, an effective pain control significantly contributes to an optimal dental treatment in pediatric dentistry.Proper pain prevention may enhance the child's cooperation by building dentist-child trust and reducing fear and/or anxiety during the current or future visit(s). The purpose of this study is to compare the efficacy of three different approaches of LA administration(Warm[37°C] LA, Buffered LA, and BUZZY device) on pain perception to young children ( 6-12 years old) using sound -eye -motor and Wong-Baker FPR scales. This study will be conducted on 80 children aged between 6-12 years from pediatric dental clinic, Faculty of Dentistry, Mansoura University. Children will be divided to 4 equal groups, 20 children each. Three experimental groups, and a (control group) . The 4 groups will be randomly allocated for each technique using block technique of simple random sampling .Randomized block designs are constructed to reduce noise or variance in the data.~Every block will include the equal number of the four groups (three experimental and one control).
The aim of the study is to compare the efficacy of three different approaches of local anesthesia (LA) administration (Warm[37°C] LA, Buffered LA, and BUZZY device) on pain perception to young children ( 6-12 years old) using sound -eye -motor and Wong-Baker FPR scales.
