The goal of this interventional randomized clinical trial is to test the effect of magnification and clinical experience of the operator on the success rate of full pulpotomy in mature adult molar teeth.

The main questions it aims to answer are:

• Does the use of magnification raise the success rate of full pulpotomy of mature adult molars?
• Does the clinical experience of the operator dentist raise the success rate of full pulpotomy of mature adult molars?

Participants will be asked to do the following:

• Receive the pulpotomy treatment of their target molar tooth.
• Record the pain score in the pain assessment chart.
• Attend the follow-up visits. They'll receive a full pulpotomy treatment of their target molar tooth. Researchers will evaluate the usage of magnification in performing the pulpotomy procedure of adult molar teeth by postgraduate or undergraduate operators in comparison to performing the same pulpotomy procedure without magnification to see if it raises the overall success rate of pulpotomy.
