What is the most appropriate treatment for a pinpoint exposure on a permanent tooth with an open apex?

  1. Splint

  2. Repositioned orthodontically

  3. Pulpotomy with CaOH

  4. Primary endo

The correct answer is: Pulpotomy with CaOH

A pinpoint exposure on a permanent tooth with an open apex is a dental condition that requires prompt treatment in order to prevent further damage to the tooth. While all of the options may seem plausible, the most appropriate treatment for this condition is a pulpotomy with Calcium Hydroxide (CaOH). A splint may be used for stabilization if there is tooth mobility, but it will not address the underlying issue of the pinpoint exposure. Repositioning orthodontically may be used in certain cases, but it is not a suitable treatment for a pinpoint exposure. Primary endo is not recommended as it involves the complete removal of the pulp rather than addressing the pinpoint exposure.
