Nitrous Oxide Increases Success Rates of Pediatric Dental Procedures

Researchers in the new issue of Anesthesia Progress test the success rates of children pre-medicated with ibuprofen that are then given either nitrous oxide with oxygen or oxygen alone. Their findings help to better understand the best methods of pain management for pediatric patients.

Anesthesia Progress – Anesthesia is an ongoing challenge in dentistry, especially when working to correct severe disease of the tooth pulp (irreversible pulpitis which causes spontaneous tooth pain) in adult teeth. The difficulty tends to be compounded when dentists work with pediatric patients who have irreversible pulpitis from dental caries of their permanent teeth. Young, permanent teeth in children have a larger pulp, which increases the blood and nerve supply in young teeth, thereby also increasing sensitivity. Determining the correct method of anesthesia to assist dentists in fixing these young, diseased teeth is imperative.

Researchers from the Chiang Mai University in Thailand published a novel study in the current issue of Anesthesia Progress that compared the success rates of pulpal anesthesia in children pre-medicated with ibuprofen when local anesthesia was combined with inhalation of nitrous oxide with oxygen or with oxygen alone.

The researchers performed a single-blind study in which 33 children with pulpitis of a permanent molar were included. The children were evaluated preoperatively for fear and anxiety using the Facial Image Scale and pain using the Wong-Baker FACES Pain Rating Scale (WBFPS) in case this affected their intraoperative pain perception. During the procedure, pain perception was measured with the WBFPS. Both scales are easily understandable by children and use pictures of faces that express emotions. Each child was given ibuprofen with a meal approximately 1 hour before the procedure. Seventeen children were then randomly assigned to the nitrous oxide group and 16 to the oxygen group. Once the gas was administered, the children were given nerve blocks to numb the area, and once numb, the procedure commenced.

The researchers measured the success of the procedure based on the results of the WBFSP. The WBFSP is rated on a 0 to 10 scale correlating to "does not hurt" to "hurts the worst." The method of anesthesia was considered a failure if the score was higher than 4 during any part of the procedure. Overall, the results showed a success rate of 71% in the nitrous oxide group; this was 52% higher than the success rate of the oxygen group. Compared with previous local anesthesia studies using nitrous oxide but without preoperative ibuprofen, these results showed an increased success rate in the combination of ibuprofen before the procedure and nitrous oxide during the procedure.

Given these results, the researchers concluded that local anesthesia with nitrous oxide inhalation sedation combined with preoperative ibuprofen could have an increased success rate of pulpal anesthesia in cases of severe pulpitis in pediatric patients. They also believe that these results will benefit from further studies using a larger sample size.
