Behavior of Children Related to Numbness After Dental Local Anesthesia

This study is not yet open for patient recruitment

Verified by Hadassah Medical Organization August 2006

Sponsored by: Hadassah Medical Organization
Information provided by: Hadassah Medical Organization
ClinicalTrials.gov Identifier: NCT00363207


In children, behavior management is critical to the success of pediatric dental procedures. Most of the studies on local anesthesia performed in children deal with the question how to avoid or minimize pain during injection. Due to the sensation of numbness children scratch the soft tissues and bite lips and tongue. In many cases, this may be kept in children's memory as a "painful experience" and may affect their behavior in the following visit. The purpose of this study is to evaluate children's reactions to the administration of local anesthetic injection in the mandible (mandibular block) and in the maxilla (supraperiosteal infiltration), and to assess their behavior in the following visit related to each type of injection.
