How long does it take to see the dentinal bridge after direct pulp capping using Calcium hydroxide?

The formation of a dentinal bridge following direct pulp capping with calcium hydroxide typically occurs within a timeframe of 6 to 8 weeks. This period is essential as it reflects the biological response of the dental pulp to the traumatic exposure and the subsequent healing process initiated by calcium hydroxide, which promotes reparative dentin formation.

Calcium hydroxide acts as a vital pulp capping material due to its ability to stimulate the pulp to produce a protective barrier. The time frame of 6 to 8 weeks is supported by clinical studies that observe the cellular response and the deposition of dentin in this interval, allowing for the assessment of effective healing and sealing of the pulp. Although options suggesting shorter or longer durations are provided, they do not align with the established biological timelines for dentinal bridge formation associated with calcium hydroxide. This solidifies the correct answer as the one indicating 6 to 8 weeks for optimal healing and dentin bridge development.
