A IMPORTÂNCIA DOS ESTUDOS CLÍNICOS RANDOMIZADOS E SEU IMPACTO NA TOMADA DE DECISÃO CLÍNICA

Abstract

Randomized clinical trials (RCTs) are considered the gold standard and the highest level of scientific evidence, preceded only by systematic reviews with or without meta-analysis. Both policy makers and guideline developers need to use such studies, as well as systematic reviews of RCTs, to develop high-quality clinical guidelines to assist dentists in making clinical decisions. Therefore, randomized controlled trials need to be well designed and have a reduced number of systematic errors to build reliable scientific evidence regarding the benefits and side effects of clinical interventions, as well as to ensure transparency in the design of study
methodology and reporting of results, all of which will reduce potential biases. Poorly designed clinical trials pose a risk to clinical practice, as well as a waste of time and effort for dentists and even a waste of resources in science. This commentary aims to highlight and discuss problems related to the quality of randomized controlled clinical trials and their effect on dental surgeons’ clinical decision making, as well as emphasizing the importance of choosing high quality clinical trials as a basis for their clinical practice.
