Efficacy of Topical Anesthetics in Pain Perception During Mini-implant Insertion: Systematic Review of Controlled Clinical Trials.

The focus of this systematic review is to assess the efficacy of several commonly utilized anesthetic techniques for reducing pain during the placement of mini-implants. An electronic search was conducted in the databases PubMed, Scopus, Web of Science, Medline Complete, Cochrane, Trials Central, and Clinical Trials, without limitations on year of publication or language. Randomized controlled trials (RCTs) and controlled clinical trials (CCTs) were considered. Two reviewers of articles independently evaluated the results of the study, and the risk of bias of included articles was evaluated according to the Cochrane Scale. Five eligible articles (3 RCTs and 2 CCTs) were included. The quality of the body of evidence was considered low because of the presence of multiple methodological problems, high risks of bias, and heterogeneity in the articles included. There was evidence that the efficacy of the analgesia of infiltrative anesthesia was most effective in promoting a lower perception of pain compared to the other anesthetic agents, although an injection was required. Among topical anesthetics, compound topical anesthetics with 20% lidocaine were more effective than compound topical anesthetics with low lidocaine concentration and conventional topical anesthetic with 20% benzocaine.

PERFIL, MOTIVOS DE INGRESSO E DE EVASÃO DOS GRADUANDOS DE ODONTOLOGIA / Profile, reasons for entrance and dropout of dental students

A escolha profissional não é fácil, porque muitas angústias cercam esse processo. Assim, o presente trabalho teve como objetivo traçar o perfil e identificar os motivos de ingresso e evasão dos acadêmicos de Odontologia da Universidade Federal de Campina Grande. O estudo foi do tipo transversal, observacional, adotando como estratégia de coleta de dados o questionário. A amostra foi composta por 144 alunos regularmente matriculados no Curso de Odontologia da UFCG, cujo ingresso ocorreu no ano de 2013 e 2012 e no segundo semestre de 2011. A caracterização sociodemográfica dos discentes revelou que a maioria é do gênero feminino (69,4%), oriundos do Estado da Paraíba (53,5%) e residem com os amigos (49,3%). Dentre possíveis causas de evasão, 59% dos graduandos afirmaram ter prestado vestibular para outros cursos antes de ingressar na odontologia e 22,9% ainda pretendem se submeter a um novo vestibular. Quanto aos motivos de escolha, a maior parte dos participantes respondeu o fato da odontologia ser da área de saúde (30,1%) e a vocação (28,7%). Observou-se diferença estatisticamente significante entre as variáveis "prestar um novo vestibular" e "ocorrência de insatisfação com o curso" (p = 0,03). Assim, apesar de um número moderado de acadêmicos relatar a vontade de prestar novo vestibular, a maioria está satisfeita com o curso.

The career choice is not easy, because a lot of feelings encircle this process. This study had the objective to set the profile and identify the reasons for entrance and dropout of undergraduate dental students from Federal University of Campina Grande. It was a transversal, observational study, using a questionnaire as a strategy for data collection. The sample consisted in 144 students regularly enrolled on the dental undergraduate of Federal University of Campina Grande, which the entrance was in 2013 and 2012 and second semester of 2011. The socio demographic characterization of the students revealed that the majority is female (69.4%), from State of Paraiba (53.5%) and live with roommates (49.3%). Among the possible reasons for dropout, 59% said they had done a college entrance exam for another course before entrance in the dental graduation and 22,9% intend to have a new college entrance exam. About reasons of choosing, most participants answered that dentistry is part of healthcare (30.1%) and vocation (28.7%). There were statistically significant differences between the variables "having a new college entrance exam" and the dissatisfaction with the course (p = 0.03). So, in spite of a moderate number of students reported the wish to have a new college entrance exam, most of them are happy with the course.
