This study will compare the outcome of endodontic treatment using conservative or traditional access design in permanent molars with clinical signs indicative of irreversible pulpitis


After thorough history and clinical and radio graphic examination, and confirmation of eligibility for the study, written informed consent will be obtained after explaining the procedure and its associated risks and benefits.

Clinical diagnosis of symptomatic irreversible pulpitis will be established based on a history of spontaneous pain or pain exacerbated by cold stimuli and lasting for a few seconds to several hours (lingering pain) compared to control teeth and which is reproducible using cold testing.

Once included, study subjects will be randomly allocated to either traditional access or conservative access group. Subsequently biomechanical preparation will be carried out using standard protocol with the use of rotary NiTi file system followed by root canal filling using gutta percha and zinc oxide eugenol sealer. Teeth will be restored using composite resin in the same appointment.

Pain analysis will be carried out preoperatively and postoperatively at every 24 hours till 7 days after intervention. All the subjects will be followed up for evaluation of success at 6 and 12 months from baseline.
