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

Clinical Evaluation of 3D Printed Resin Based Crowns Versus Stainless Steel Crowns in Pulpotomized Primary Mandibular Molars : A Randomized Controlled Clinical Trial

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.

primary mandibular molars will be randomly assigned to receive either 3D-printed resin-based crowns or stainless steel crowns. Following pulp therapy and crown placement, participants will attend follow-up visits over a 12-month period. Clinical evaluation will be performed to assess gingival health, plaque accumulation, crown retention, and child and parent satisfaction, in order to determine whether 3D-printed resin-based crowns can be an effective esthetic alternative to stainless steel crowns.

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.
