An alternative local anaesthesia technique to reduce pain in paediatric patients during needle insertion

ABSTRACT

Aim

AIM Pain control, which is necessary during most dental procedures, is administered by injecting a local
anaesthetic. Because the injection itself can be painful, the procedure via which pain is reduced warrants continued
investigation. Only a few studies regarding the reaction of children to dental needle insertion without the use of topical
anaesthetics have been reported. This study was conducted to evaluate the efficacy of the local anaesthetic procedure
without topical application as compared to the conventional insertion technique for alleviating pain in children receiving
local anaesthesia injections.
MATERIALS AND METHODS For the alternative injection procedure, the dentist quickly and gently pulled or pushed the
clean and dried loose tissue at the injection site over the tip of the needle to a depth of 1 to 1.5 mm. When the end of the
bevel of the needle tip entered the tissue, a few drops of solution were released, after which the needle was advanced to its
proper and intended depth to continue anaesthetic release.
RESULTS There was a significant difference regarding the pain response between the alternative insertion technique (less
painful) and the conventional one according to Sound, Eye, and Motor (SEM) scale ratings (P < 0.000). No significant difference was observed in the response between the maxilla and mandible, nor between boys and girls, between the conventional and alternative techniques. CONCLUSION This alternative technique can reduce discomfort in paediatric dental patients and allow the clinician to administer a superficial local anaesthesia injection before the needle is advanced into deeper tissue. This technique is simple, quick, devoid of additional costs, and potentially more effective than the conventional needle insertion method.
