In which scenario would a calcium hydroxide pulpotomy be appropriate?

A calcium hydroxide pulpotomy is performed when the pulp tissue is vital and there is some degree of exposure due to caries or other damage, such as the visible pulp horn scenario mentioned. This procedure aims to maintain the vitality of the remaining pulp tissue while allowing for healing and closure of the pulp chamber. Calcium hydroxide serves as a protective liner and has properties that promote healing and dentin formation.

When a tooth has a visible pulp horn but retains pulpal vitality, a pulpotomy with calcium hydroxide can be effective. This is because the pulp tissue is still healthy enough to respond positively to treatment, and the material can help protect the pulp and promote healing.

In contrast, options involving non-vital teeth, significant pulp damage, severe decay, or abscessed teeth generally do not warrant a pulpotomy with calcium hydroxide, as these conditions suggest irreversible pulpitis or necrosis, for which alternative treatments, such as root canal therapy, are more appropriate.
