Evaluation of the Injection Pain with the Use of Vibraject during Local Anesthesia Injection for Children: A Randomized Clinical Trial.

AIM
To compare the outcomes of the conventional syringe and the outcomes of the vibraject-assisted injection (VAI) in terms of the pain of the needle insertion during various intraoral injections of local anesthesia in children aged 6-9 years.


MATERIALS AND METHODS
A total number of 75 children aged 6-9 years were selected from patients visiting the pediatric dental clinic at Damascus University. The children were assigned into three equal groups (25 children each) according to the type of intraoral injection needed for the treatment: Groups [Group I: received upper buccal infiltrations (UBI), Group II: received posterior palatal infiltrations (PPI), and Group III: received inferior alveolar nerve block (IANB)]. This study was conducted considering the split-mouth design. Each child was subjected to both anesthetic injections: the conventional and the vibration-assisted in two separate dental visits 2 weeks apart. At each clinic visit, subjective and objective pain levels were assessed using the visual analog scale (VAS) and Face, Leg, Activity, Cry, Consolability (FLACC) scale.


RESULTS
Children who received local anesthesia using the Vibraject method had lower VAS and FLACC scores than those who received local anesthesia using the conventional method.


CONCLUSION
Vibraject was more effective in reducing the pain with local anesthetic injection compared to the conventional injection technique in clinical dental procedures for children.


CLINICAL SIGNIFICANCE
In a pediatric dental clinic, pain management is considered a pillar that influences actions. Using the VAI may achieve the ease, cooperation, and compliance during the dental care session.
