Effect of Epigallocatechin-3-Gallate Solution as a Root Canal Irrigant on Post-Operative Pain Intensity and Bacterial Load Reduction in Necrotic Tooth

Cairo University40 enrolled

Overview

clinically compare the intensity of post-operative pain and the amount of bacterial load reduction after using 20% Epigallocatechin-3-gallate solution during chemomechanical preparation, versus 2.5% NaOCl, in asymptomatic necrotic mandibular premolars treated in a single visit.

The patients will be randomly divided into 2 groups. Intervention group (20% epigallocatechin-3-gallate solution root canal irrigant) and control group (2.5% sodium hypochlorite root canal irrigant). Post-operative pain will be measured at 6, 12, 24 and 48 hours post-operatively. The pain will be recorded using the Numerical Rating Scale (NRS). Amount of bacterial load reduction The intracanal bacterial load reduction will be determined using agar culture technique by counting the colony forming units per milliliter (CFUs/mL) before and after root canal preparation.

Postoperative pain

Categorical None 0 Mild 1-3 Moderate 4-6 Severe 7-10

Time frame: Postoperative pain measured at 6, 12, 24, 48 hours after single visit treatment.

Secondary Outcomes

Amount of intracanal bacterial load reduction

The intracanal bacterial load reduction will be determined using agar culture technique by counting the colony forming units per milliliter (CFUs/mL) before and after root canal preparation

Time frame: T0: preintervention, preinstrumentation after access cavity. T1: postinstrumentation up to 10 min
