TRIAL DESCRIPTION
Public title Clinical evaluation of the effect of MTAD versus Propolis irrigation on necrotic primary teeth in children
Official scientific title Clinical evaluation of the effect of MTAD versus Propolis
Brief summary describing the background
and objectives of the trial
Effective irrigation is essential in canal debridement, because instrumentation alone is insufficient, and inadequate canal debridement can leads to a decrease in successful outcomes. (Howard et al, 2011) The aim of this study is to investigate the effect of Propolis irrigation versus MTAD (Mixture of tetracycline isomer, an acid, and a detergent) irrigation on: 1-Pain assessment. 2-Count of intracanal bacteria 3-Size of periapical radiolucency.
