Pain assessment during mandibular nerve block injection with the aid of dental vibe tool in pediatric dental patients: a randomized clinical trial.

Abstract

OBJECTIVE:

This study aimed to evaluate the effectiveness of DentalVibe in pain reduction during local anesthetic injection compared to traditional injection in pediatric patients.

METHOD AND MATERIALS:

This cross-over randomized controlled clinical trial included a sample of 60 children, aged 5 to 7 years, who were selected based on the need for local anesthesia for bilateral mandibular pulpotomy treatment. They were randomly allocated into two groups. Each group received two mandibular nerve block injections, with a 2-week interval as the washing out period. At first appointment, mandibular nerve block injection was performed either with vibration using DentalVibe at the injection site or benzocaine gel 20% applied before local anesthetic injection; the alternative technique was used at the second appointment. In each visit subjective pain was evaluated using the Wong-Baker FACES Pain Rating Scale and objective pain was evaluated using the FLACC (Face, Legs, Activity, Cry, Consolability) scale.

RESULTS:

Assessment using the Wong-Baker FACES Pain Rating Scale showed that the mean pain levels in DentalVibe and traditional injection groups were 0.80 ± 1.34 and 2.60 ± 3.22, respectively. The mean pain levels according to the FLACC scale were 2.20 ± 2.04 and 3.13 ± 2.30 in the DentalVibe and traditional injection groups, respectively. Both scales showed statistically significant differences between the two groups in favor of DentalVibe (P < .001). A positive significant correlation between the two scales in the two interventions was recorded, where the Spearman rho was 0.41 for the DentalVibe group, and 0.52 for traditional injection group (P < .001).

CONCLUSION:

Compared to the traditional approach, DentalVibe reduced pain sensation during mandibular nerve block injection in pediatric patients.
