About

the aim of this study is to compare the effect of using Diclofenac Sodium Versus Calcium Hydroxide as Intracanal medication on intensity of postoperative pain, bacterial load reduction after root canal preparation and periapical matrix metalloproteinase 9 level (MMP-9) post-instrumentation and pre-obturation in teeth with necrotic pulp

Full description

To compare the effect of diclofenac sodium versus calcium hydroxide as intra canal medication on:

Primary Outcome Intensity of postoperative pain will be measured using numerical rating scale (NRS) at 6, 12, 24 and 48- hours post-instrumentation and at 6, 12, 24 and 48 hours post-obturation.

Secondary Outcome 1 Bacterial load reduction will be determined by bacterial counting using agar culture technique after root canal preparation (CFU/ml).

Secondary Outcome 2 Periapical MMP-9 level will be determined post-instrumentation and pre-obturation by ELISA.
