CABO VALLE, M.; DELGADO RUIZ, R.  e  CABO DIEZ, J.. Effectiveness of dental use of topical anesthesia prior to puncture and infiltration of the anesthetic: Double-blind study. Av Odontoestomatol [online]. 2011, vol.27, n.2, pp.99-105. ISSN 2340-3152.

Purpose: To test the effectiveness of topical benzocaine gel in reducing the pain of the puncture and infiltration of anaesthesia, in vestibular mucosa of upper canine. Material and Methods: We conducted a double blind study on 152 patients (80 men and 72 women), who needed anaesthesia in the buccal mucosa of the canine area. We value the patient's pain to pinprick and infiltration, and the existence of prior experience painful or not painful to puncture and infiltration of the anaesthetic. Results: The results confirmed the effectiveness of benzocaine to reduce the pain of a prick (p<0.005) and the effectiveness of benzocaine in reducing pain in patients with painful past experiences (p<0.005). Benzocaine did not diminish the pain of anaesthetic infiltration (p>0.005).
