A tooth’s outer portion or Crown consists of a three-layered structure, including Enamel, Dentin, & Pulp. If the tooth decay is limited to the first two layers, it can be corrected with Filling or Restoration. In case the tooth decay reaches the third layer and causes inflammation or infection of the pulp, a Root Canal Treatment ( RCT ) is needed. What is Root Canal Treatment? Root Canal Treatment ( RCT ) or Endodontic Treatment, is a dental procedure done when tooth decay reaches the pulp ... Randomized controlled trials ( RCT ) are prospective studies that measure the effectiveness of a new intervention or treatment. Although no study is likely on its own to prove causality, randomization reduces bias and provides a rigorous tool to examine cause-effect relationships between an intervention and outcome. This is because the act of randomization balances participant characteristics (both observed and unobserved) between the groups allowing attribution of any differences in outcome ... Randomized controlled trials (RCTs) are considered the highest level of evidence to establish causal associations in clinical research. There are many RCT designs and features that can be selected to address a research hypothesis. Designs of RCTs have become increasingly diverse as new methods have … A randomized controlled trial (or randomized control trial; RCT ) is a type of scientific (often medical) experiment that aims to reduce certain sources of bias when testing the effectiveness of new treatments. It is a trial in which subjects are randomly assigned to one of two groups: one (the experimental group) receiving the intervention that is being tested, and the other (the comparison group or control) receiving an alternative (conventional) treatment. The two groups are then followed ...
