Comparison of Eggshell-derived Calcium Hydroxyapatite and Biodentine as Indirect Pulp-capping Agents in Primary Molars: In Vivo Study

For a pulp-capping material to be considered ideal, it must support hard-tissue formation, preserve pulp vitality and functionality, promote the formation of a dentin bridge, possess suitable physical properties, ensure strong adhesion to dentin, and be easy to handle during dental procedures. 4everal materials are utilized for IDPC, such as mineral trioxide aggregate (MTA), Portland cement (PC), calcium hydroxide (CH), IntroductIonThe preservation of primary teeth plays a vital role in pediatric dentistry.Ensuring their integrity is essential, as the condition of primary dentition serves as an indicator of a child's general health.Premature loss of primary teeth is most commonly attributed to dental caries.The fundamental aim of pulp therapy in deciduous teeth is to maintain their integrity and function until natural exfoliation, a prerequisite for the optimal development of the facial and skeletal complex. 1 The dental pulp performs essential biological functions, including protection, nutrition, sensation, and dentin formation.Preserving its vitality remains a primary objective in restorative management of teeth affected by caries or trauma, as it is crucial for maintaining tooth integrity and long-term oral health. 2 Endodontic treatment in primary teeth is generally classified into two types: Vital pulp therapy (VPT) and root canal treatment (RCT).VPT aims to address reversible damage to the pulp and to sustain its vitality and functionality. 3ital pulp therapy encompasses three main treatment modalities: Indirect pulp capping (IDPC), indicated for teeth with deep dentinal caries and reversible pulpitis; and direct pulp capping (DPC) or pulpotomy, which are employed in cases involving pulp exposure.
