• Aim: To investigate the possible reduction of the need for dental general anesthesia (DGA) through nitrous oxide sedation (NOS), when is used in combination with behavior management techniques among patients younger than 12 years of age referred to a specialized pedodontics practice due to the high dental treatment need and poor cooperation level. Materials and methods: Retrospective analysis was performed of the digital medical records of all children treated under NOS in a specialized pedodontics clinic between 2012 and 2017. The potential reduction of the need for dental general anesthesia was assessed depending on the success rate of NOS on patient-level with relations to multiple related factors such as age, reason of referral and treatment need. Results: out of 510 patients, 228 meet the inclusion criteria. Nitrous oxide was used in 406 dental treatment sessions on 228 pre-cooperative and/or anxious patients aged 3-12 years (mean 6.4±1.7; 43.4% female). 91.9% of the NOS sessions were successful in achieving the intended dental treatment. Complete oral rehabilitation was possible for 84% of the patients using NOS without the need of DGA. Regarding the age, DGA reduction among pre-school children was lower than in schoolchildren (77.8% and 87.9%, respectively). Conclusion: A high fraction of anxious or semi-cooperative children with high dental treatment needs can be treated without the use of DGA when a comprehensive concept of caries management is combined with the use of NOS and behavior management techniques. NOS should, therefore, always be considered as an option for dental treatment of semi-cooperative children with high dental treatment needs before making a decision towards DGA.
