Comparison between Restorative Materials for Pulpotomised Deciduous Molars: A Randomized Clinical Study.

Area of Science:

• Pediatric Dentistry
• Restorative Dentistry
• Dental Materials

Background:

• Pulpotomy is a common procedure for primary molars with deep caries.
• Restorative materials play a crucial role in the long-term success of pulpotomy.
• Stainless steel crowns (SSCs) are a traditional choice, while Cention-N (CN) is a newer alternative.

Purpose of the Study:

• To compare the clinical and radiographic outcomes of Cention-N and stainless steel crowns in restoring pulpotomized primary molars.
• To evaluate the marginal integrity, proximal contacts, gingival health, and secondary caries development for both restorative materials.

Main Methods:

• A randomized controlled trial involving 60 pulpotomized primary molars with occlusoproximal caries.
• Molars were restored with either stainless steel crowns or Cention-N.
• Clinical and radiographic assessments were performed at 6, 9, and 12 months.

Main Results:

• Both Cention-N and stainless steel crowns demonstrated comparable marginal integrity and overall clinical/radiographic success rates at 12 months.
• Stainless steel crowns showed significantly better maintenance of proximal contacts.
• Cention-N exhibited notably better gingival health outcomes.
• No significant secondary caries or discomfort on biting was observed in most cases.

Conclusions:

• Cention-N and stainless steel crowns are comparable restorative options for pulpotomized primary molars.
• Material choice may depend on prioritizing proximal contact maintenance (SSC) or gingival health (Cention-N).
• Both materials provide favorable outcomes regarding secondary caries and patient comfort.
