Resin-containing Ca(OH)2 uninfected pulp undergoes which healing?

• A. necrosis
• B. inflammation
• C. granuloma formation
• D. uncomplicated healing

Answer: (D)

When the pulp is uninfected and a resin-containing calcium hydroxide liner is used, the healing response is uncomplicated. Calcium hydroxide creates a strongly alkaline environment that stimulates the pulp’s odontoblastic activity to lay down reparative dentin, forming a protective dentin bridge. The resin component helps seal the interface and reduce microleakage, which minimizes irritants reaching the pulp. As a result, the pulp remains vital and any initial inflammation is mild and transient, resolving without progression to tissue death or chronic inflammatory lesions. Therefore, the expected outcome is uncomplicated healing with preservation of vitality and hard tissue barrier formation.
