Abstract

Introduction: Children often develop phobia toward needle pricks and invasive
procedures. Unmanaged pain could result in short and long-term physiological,
psychological, and emotional consequences. Aim: The aim of this study wasto compare
the effectiveness of (Buzzy Bee device) versus traditional topical anesthesia 20%
benzocaine gel in management of pain and anxiety during nerve block and infiltration
for maxillary and mandibular primary molars in children. Materials and methods:
A randomized, split-mouth study was conducted on 60 children aged 4-6 years, with
no previous dental experience, who required maxillary infiltration or inferior alveolar
nerve block for pulpotomy in the maxillary or mandibular primary molars. The children
were divided equally into two main groups, nerve block (n=30) and infiltration groups
(n=30). Then each group was subdivided into Buzzy Bee device subgroup (examined
side) and topical anesthesia 20% benzocaine gel subgroup (control side), followed
by pulpotomy or extractions. An assessment of the children’s pain perceptions was
conducted by the dentist, using The Face Legs Activity Cry Consolability (FLACC)
Scale, while anxiety levels of children were assessed by Venham’s anxiety and
behavioral rating scale (VCARS), recorded during and after administration of local
anesthesia. Data were analyzed for statistical significance (p<0.05). Results: There was
a very highly significant reduction in anxiety assessment by (VCARS), during and after
injection of LA using Buzzy Bee device (P<0.001***). According to pain assessment
by (FLACC) Scale, effective reduction during and after injection of local anesthesia
observed when using Buzzy Bee device (P<0.001***) in both groups. Conclusion:
In pediatric patients, the Buzzy Bee device dramatically lessens the impression of
pain during local anesthetic deposition. The device could be used as a supplement to
standard dental procedures when giving children local anesthetic.
