<prompt> Which of the following results, if ZOE and CaOH2 liners are used together?No reparative dentin formationExothermic heat released after the reaction will damage the pulpHigh solubility of combinationAll of the above  <response>: Eugenol and calcium hydroxide cannot be incorporated into the same formulation, because eugenol rapidly chelates calcium ions in a strongly exothermic reaction.Therefore, the choice of a eugenol-based versus calcium hydroxide-based liner is based on the relative depth of the tooth preparation.
