<![CDATA[Introduction: Single visit root canal treatment (RCT) versus the multiple visit RCT has been the subject of a long standing debate within the dentist. Some of the unresolved issues include differences in clinical outcomes, inadequate microbial control and pain. In other hand, patients have no time to come in many appointments. Case: A19-year-oldfemalepatientcamewithacomplaint of uncomfortable over her first left mandibular molar.There was composite restoration on occlusal aspect of the tooth with no mobility and swelling.
