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.
