Comparison Between Vibraject Device and Topical Anesthesia in the Reduction of Perception of Pain to Anesthetic Puncture Intraoral

Objectives: To test the efficacy of a recent intraoral infiltrative local anesthesia delivery system that makes use of Vibraject vibratory device as a redutore of pain perception to the puncture, and in turn to compare it with the traditional system that makes use of topical anesthetic substances.
Methods: A sample of 90 patients of legal age was selected who attended at the Luz y Vida University Dental Clinic in the city of Montemorelos, Nuevo León. The most used anesthetic techniques were applied in the experiment implementing topical anesthesia and also the Vibraject device as reducers of pain perception to the puncture. The 90 participants were divided into three groups, each group was given both anesthetic systems in a specific puncture site. The level of pain experienced by patients was evaluated by using the Visual Analogue Scale (VAS) and also the
Campbell Pain Scale.
Results: The results proved the superiority of the recent local anesthesia delivery system that makes use of the Vibraject over the well-known traditional system that implements topical anesthetics in patients punctured in the palate area. Significance was demonstrated with the " Chi squared" statistical test.
Thus affirming that the Vibraject device is more effective than its competitor in this studio. The effect size has also been measured using the formula of the “De de Cohen”, the value obtained was 0.408392, which indicates that the Vibraject has a 98 medium effect in reducing pain perception over technique conventional anesthetic.
Conclusions: The Vibraject device manages to reduce the perception of pain during the infiltration of local anesthetic in the palate area, we can theorize that this is because the masticatory mucosa in addition to being dense and fibrous, it is firmly adhered the bone tissue, which favors the transmission of the vibrations of the needle, thus reducing the perception of pain as suggested by the gate theory.
