Comparative Evaluation of Clinical and Radiographic Success Rates of Direct Pulp Capping in Primary Molars Using TheraCal LC, 3Mixtatin, and Nanohydroxyapatite: An In Vivo Study
Year: 2026
Type: article
Abstract: Aim and background: study evaluated and compared the clinical and radiographic efficacy of three pulp capping agents-TheraCal light-cured (LC), 3Mixtatin, and nanohydroxyapatite (NHA)-for direct pulp capping (DPC) in primary molars. The goal aligns with the modern focus of pediatric dentistry on pulp revitalization and the preservation of primary teeth until exfoliation. Methods: = 15 per group) to receive TheraCal LC, 3Mixtatin, or NHA. All treatments were sealed with zinc oxide eugenol and restored with type IX glass ionomer cement. Clinical and radiographic assessments-evaluating pain, swelling, sinus tract, percussion sensitivity, mobility, secondary caries, root resorption, furcal radiolucency, and periodontal ligament (PDL) widening-were conducted at 3, 6, and 9 months. The collected data were analyzed using the Chi-square test with the aid of Statistical Package for the Social Sciences (SPSS) software. Results: < 0.01). NHA maintained 100% success at 6 months and 93.3% at 9 months both clinically and radiographically. Conclusion: Nanohydroxyapatite exhibited the highest and most consistent success over the 9 months, outperforming both TheraCal LC and 3Mixtatin in sustaining pulp vitality. Clinical significance: The success of DPC in primary teeth is largely influenced by the use of materials with optimal biological compatibility. NHA demonstrated superior outcomes, offering effective pulp preservation and reducing the need for invasive treatments. How to cite this article: Study. Int J Clin Pediatr Dent 2026;19(2):215-222.
