This trial aims to compare treatment outcomes between Pulpotomy and Pulpectomy in treating vital primary teeth diagnosed with deep caries with symptoms of irreversible pulpits

Background: Pulpectomy is the reference treatment for vital primary molars with irreversible pulpitis.Over the past decades, dental caries has unfailingly been the most common chronic infectious disease of childhood and adults. If remained untreated, it can potentially compromise dental pulp tissue. When the dental pulp of primary teeth is irreversibly inflamed, the first treatment choice is pulpectomy, owing to the well-recognized importance of primary tooth retention for child oral/general health. Although a pulpless tooth can remain functional in the oral cavity, modern pediatric endodontics encourages regenerative approaches in primary teeth.The introduction of calcium silicate-based (CS-B) biomaterials such as mineral trioxide aggregate (MTA), along with further understanding of pulp biology and inflammatory processes, has revolutionized treatment modalities for management of irreversible pulpitis in mature permanent teeth. A growing body of evidence has revealed successful implementation of minimally invasive endodontics, that is, vital pulp therapies (VPTs) for management of permanent teeth with irreversible pulpitis even when associated with apical periodontitis. Due to the traditional notion of poorer healing capacity of primary dental pulp, such a paradigm shift has not been seen in pediatric dentistry.Recent research revealed similar vascular/immune responses of primary and permanent dental pulps to caries; therefore, indicating that their healing potential might be this in mind, a reevaluation of traditional approaches for treatment of inflamed primary pulp seems justified.

Inclusion Criteria:

4. Restorable teeth.

Exclusion Criteria:

1. Physical or mental disability.
2. Unable to attend follow-up visits.
3. Previously accessed teeth.
4. Swelling, tenderness to percussion or palpation, or pathological mobility.
5. Pre-operative radiographic pathology such as resorption (internal or external), per-radicular or furcation radiolucency.
