A randomized clinical trial was performed to explore the efficacy of a novel intraoral vibratory device (lowers pain by delivering vibration at a sustained frequency as a counter-stimulation to the injection site) vs. lignocaine hydrochloride 2% gel in alleviating pain during IANB procedure in children.
In children, both novel intraoral vibratory device and lignocaine
hydrochloride 2% gel were found to be equally effective in pain alleviation
during inferior alveolar nerve block (IANB).
A
randomized clinical trial was performed to explore the efficacy of a novel
intraoral vibratory device (lowers pain by delivering vibration at a sustained
frequency as a counter-stimulation to the injection site) vs. lignocaine
hydrochloride 2% gel in alleviating pain during IANB procedure in children.
The split-mouth study cohort recruited 60 children (aged 6-12 years) that required bilateral IANB for dental procedures. The vibratory device was utilized while administering IANB and lignocaine hydrochloride gel was utilized as the topical anesthetic prior to administering IANB at subsequent appointments.
The pain perception was estimated utilizing the Wong-Baker faces pain rating scale
(WBFPRS) and sound, eye, motor (SEM) scale. Utilizing a pulse oximeter prior
to, during, and after IANB, the oxygen saturation and pulse rate were
estimated. The procured values were tabulated. Statistical analysis was done.
For intergroup comparison, the wilcoxon test was utilized and for intragroup
comparison of measured variables at different therapeutic phases, the Friedman
test was utilized.
During IANB, the medians and interquartile
ranges of WBFPRS scores recorded for lignocaine hydrochloride gel and vibratory device were 2 (0–2) and 2 (2–4)
respectively. No vital differences between both the therapies in the SEM scale
scores, mean oxygen saturation, and pulse rate were witnessed during the IANB
procedure.
The novel vibratory device and
lignocaine hydrochloride gel effectively lower pain during procedure IANB in
children.
