3D-Printed Resin Crowns vs Stainless Steel Crowns in Pulpotomized Primary Molars.

The goal of this clinical trial is to learn whether 3D-printed resin-based crowns are an effective alternative to stainless steel crowns for restoring pulpotomized primary mandibular molars in children. The main questions it aims to answer are: Do 3D-printed resin-based crowns provide better gingival health than stainless steel crowns? Are there differences in plaque accumulation, crown retention, and child and parent satisfaction between the two crown types? Participants will: Receive either a 3D-printed resin-based crown or a stainless steel crown after pulpotomy. Attend follow-up visits for clinical evaluation over 12 months.

Inclusion Criteria: Children aged 4 to 8 years. Cooperative children who are able to accept dental treatment. Teeth diagnosed with reversible pulpitis. Children in good general health with no systemic conditions affecting oral health. Parents/guardians willing to provide written informed consent and attend follow-up visits. Exclusion Criteria: Teeth deemed non-restorable (e.g., gross carious destruction or fractures beyond restoration). Parents/guardians unwilling to participate in the study or provide informed consent.
