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.
