This randomized double-blind crossover trial investigated the discomfort associated with 2 injection speeds, low (60 seconds) and slow (100 seconds), during inferior alveolar nerve block by using 1.8 mL of 2% lidocaine with 1 : 100,000 epinephrine. Three phases were considered: (a) mucosa perforation, (b) needle insertion, and (c) solution injection. Thirty-two healthy adult volunteers needing bilateral inferior alveolar nerve blocks at least 1 week apart were enrolled in the present study. The anesthetic procedure discomfort was recorded by volunteers on a 10-cm visual analog scale in each phase for both injection speeds. Comparison between the 2 anesthesia speeds in each phase was performed by paired t test. Results showed no statistically significant difference between injection speeds regarding perforation (P = .1016), needle placement (P = .0584), or speed injection (P = .1806). The discomfort in all phases was considered low. We concluded that the 2 injection speeds tested did not affect the volunteers' pain perception during inferior alveolar nerve blocks.
A pesquisa objetivou investigar a autoestima e os aspectos socioemocionais de pacientes com deformidades dentofaciais submetidos à cirurgia ortognática. Disponibilizamos um questionário da plataforma Google Docs em um grupo de uma rede social composto por pessoas com interesses em comum no tema. Houve 120 respostas no total e, em geral, elas revelaram que houve aumento de autoestima nos pacientes (média geral subiu de 4,58 para 8,33) e melhora significativa em fatores funcionais, sociais e psicológicos. Contudo, existe a possibilidade de frustração para alguns sujeitos submetidos ao procedimento, oriundo das expectativas perante a cirurgia, especialmente no âmbito estético. A cirurgia ortognática é uma alternativa considerável no tratamento de deformidades dentofaciais e de seus agravos, porém, diante da pluralidade de resultados e reações, infere-se a importância de acompanhamento psicológico no pré e pós-cirúrgico, como forma de preparo para a cirurgia e de adaptação aos resultados do procedimento.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
