Comparison of effectiveness infiltration with block in anesthetizing mandibular primary molar in children aged 6-9 years old

The purpose of this study was to compare the clinical effectiveness of the mandibular infiltration versus the mandibular block for the operative and surgical treatment of primary molars. Methods & Materials: 80 children aged 6-9 years old who required bilateral identical dental treatment in mandibular primary molars were selected. Subjects received an infiltration on one side of mandible and block on the other. Bilateral identical procedure were performed on each patients during the same appointment. These procedures included amalgam restoration, pulpotomy, extraction, stainless steel crown. Sign of discomfort included hand and body tension, eye movement indicating pain, verbal complaints and tears. Both techniques were evaluated blindly by a single rater who was not the operator. T test indicated there was no significant difference between block and infiltration for any of the factors evaluated and anesthesia profundity is not as dependent upon bone density. Mandibular infiltration can be used versus block in treating mandibular primary molars.
