Dentin sealer was applied on premolars with molars as control, then provisional was given to patient cemented with non eugenol zinc oxide cement. The patient was then recalled on the 7thday. The temporary crown was removed. The post operative sensitivity was again checked with the help of airblast and by questionnaire and then final cementation was done.
