This clinical trial demonstrates no difference in pain control effectiveness between infiltration/intrapapillary injections and inferior alveolar block/long buccal infiltration for children undergoing mandibular pulpotomy and stainless steel crown placement.
These results fail to confirm suggested differences in 1 previous study. Pain control was effective overall for 91% of children. This result is qualitatively similar to the [...]

RESULTS
The mean age of children in both groups was 78 months (SD =12 months). Thirty girls were randomized into the block group and 25 girls to the infiltration group. There was no difference in the average age or proportion of girls in each group (both P > .05). Eight children (15.4%) in the block group [...]

Conditions
All children were given 40% nitrous oxide via a nasal mask. After 3 minutes, the site of the injection was dried with a cotton tip applicator, and topical anesthetic (Hur-ricaine, 20% benzocaine gel) was applied for 60 seconds. The dental hygienist then opened an envelope giving the anesthetic assignment, and local anesthetic was administered. The [...]

Subjects
Healthy children who needed a pulpotomy treatment in a lower primary molar and had no contraindication for local anesthetic were eligible for the study. On the day of treatment, after the initial consultation, parents of el­igible children requiring pulpotomy were approached by office staff and informed of the study; written informed consent of the parent [...]

The aim of this study was to test the hypothesis that dental pain control using infiltration/intrapapillary injection was less effective than inferior alveolar block/long buccal infiltration anesthesia in children. A total of 101 healthy children, aged 5-8 years, who had no contraindication for local anesthetic and who needed a pulpot-omy treatment and stainless steel crown [...]
