Frequency of hematoma formation subsequent to injection of dental local anesthetics in children.
This study investigated the frequency of hematoma formation subsequent to injection of dental local anesthetics in 4,134 children, 3 to 13 years of age. Hematoma formation occurred following 0.1% of the injections, all being buccal infiltrations of maxillary molars. This represents a 0.4% incidence of hematoma formation subsequent to this injection. There was no age specificity in hematoma formation, occurring in one 5 year old, one 7 year old, one 8 year old, one 10 year old, and one 11 year old.
