Different Methods for Reducing Buccal Infiltration Local Anesthesia Injection Pain

Different Methods for Reducing Buccal Infiltration Local Anesthesia Injection Pain in Children: A Randomized Controlled Study.

Local anesthetic injection is considered one of the most annoying dental procedures. The use of topical anesthesia is considered a routine procedure in the dental clinic especially for children. However, the taste and application procedure of the topical gel may not be pleasant for all children.

The introduction of the Buzzy device is considered a distraction measure in the medical field. Alanazi et al., 2019, studied the effect of using the Buzzy device with cold and vibration compared to the conventional infiltration technique using 30-gauge needle. They concluded that the use of the Buzzy device resulted in better patients' acceptance and significantly lower Wong-Baker scores.

Ballard et al., 2019, mentioned in their systematic review the efficacy of the Buzzy device for pain management during needle-related procedures, they concluded that the use of the device may be promising. Ghaderi et al., 2013, evaluated the effect of cooling the injection site on pain perception before infiltration of local anesthetics. They found that cooling the injection site before infiltration of local anesthetics in the buccal mucosa for 1 min, reduced pain perceived by pediatric patients.

The investigators used the topical anesthesia, Buzzy device (using vibration only and using cold and vibration) or precooling on pain during buccal infiltration local anesthesia injection.
