COMPARAÇÃO DA ACEITABILIDADE E EFETIVIDADE DO USO DE ANESTÉSICO TÓPICO E ANESTÉSICO INFILTRATIVO PARA INSTALAÇÃO DE MINIIMPLANTES ORTODÔNTICOS

Abstract

The objective of the present study was to compare the acceptability and effectiveness of topical anesthesia and infiltration anesthesia for insertion of orthodontic mini-implants used as temporary anchorage devices. The sample comprised 40 patients, 17 males and 23 females, mean age 26 years and all were in orthodontic treatment and needed anchorage. In all individuals were installed mini-implants in the maxilla bilaterally, in one side with infiltration anesthesia and opposite with topical anesthesia. These 40 patients completed two questionnaires, one before and another after the insertion, the pain measurement was made through a visual analog scale (VAS). The collected data were analyzed using descriptive statistics and the pain measurements were compared using nonparametric test of Mann Whitney. The results found that 60% of the patients felt more comfortable because of the use of topical anesthesia for the insertion of mini-implants, 72.5% of the patients described the pressure during insertion of the anchorage device as the most unpleasant sensation at all the process, 62.5% of patients felt more pain with the use of topical anesthesia. The study concluded that patients had less pain with the use of infiltration anesthesia, and also preferred this type of anesthetic.
