Rothman: Sedation and Emergency Treatment of the Pediatric Dental Patient – Part 3-Rothman Sedation and Emergency Treatment of the Pediatric Dental Patient Part 3

Video Summary

The speaker reviews a simple “local infiltration” anesthesia technique for pediatric dental treatment. Instead of injecting into the mucobuccal fold, the needle is kept parallel to the mucogingival junction, starting at the most anterior tooth being treated and moving distally to the last tooth. For back-to-back stainless-steel crowns, the injection may begin near the cuspid. The child bites down firmly for counter-stimulation; topical anesthetic is used, the cheek is retracted, and the needle is advanced slowly while continuously infiltrating, staying parallel to the occlusal plane and cortical plate. After reaching distal to the second molar, the clinician withdraws and performs a perpendicular papillary/interdental injection until blanching is seen on the lingual/palatal side, then adds a small amount to allow diffusion. Total volume is modest (about 1/2 to 2/3 cartridge), delivered slowly over ~30–45 seconds to reduce discomfort. With this approach, profound anesthesia can support procedures such as dam clamp placement, pulp therapy, and extractions; a small supplemental PDL injection is only occasionally needed. The technique is effective for immature first permanent molars in younger children, generally up to around age 7–8, and helps avoid unnecessary tongue numbness.<br /><br />He also explains why a long buccal nerve block is usually unnecessary in children: smaller mandibles and greater diffusion mean the anesthetic often covers the long buccal nerve anyway, while an added long buccal injection mainly increases unwanted lip/soft-tissue numbness without improving treatment.
