This randomized controlled clinical trial compares the antimicrobial efficacy and clinical success of normal saline, chlorhexidine, one percent sodium hypochlorite, and MTAD as intracanal irrigants in primary molar pulpectomy. Children aged four to nine years will be included. The primary outcome is reduction in intracanal bacterial load. Secondary outcomes include clinical and radiographic success at three and six months, and post operative pain within seventy two hours. The planned sample size is one hundred sixty participants.
