Intraosseous anaesthesia in children with 4 % articaine and epinephrine 1:400,000 using computer-assisted systems

Abstract : AIM: To assess retrospectively the efficacy of computer-assisted intraosseous anaesthesia (CAIO) in children using an anaesthetic solution with a lower concentration of epinephrine (1:400,000). METHODS: In a retrospective study, CAIO was evaluated in healthy children and adolescents for restorative and endodontic treatments, uncomplicated tooth extractions or scalings using articaine 4 % plus epinephrine 1:400,000. Anaesthesia was performed in children who showed enough compliance (score of 0-3 according to modified behaviour Venham scale). Efficacy, amount of anaesthetic solution as well as need of a complementary injection was assessed. RESULTS: A total of 421 consecutive sessions were performed on 278 patients aged 7.1 ± 2.9 years with 518 teeth involved in the anaesthetic process and analysed process. When teeth to be anaesthetised were considered, the overall success rate was 97.2 %. In most of the cases, only 0.9 mL was needed to achieve anaesthesia. Permanent teeth needed significantly more anaesthetics than primary teeth. Sensitivity of the teeth anaesthetized reappeared in 5.7 % of cases after 30-60 min of treatment. CONCLUSIONS: These results suggest that CAIO with 4 % articaine and epinephrine diluted 1:400,000 can be an alternative to usual infiltration techniques or IO with epinephrine at a higher concentration for most of treatments in primary and permanent teeth. Further studies are needed to evaluate its efficacy in permanent teeth in case of endodontic treatment or extraction
