MELD score will be recorded in cirrhosis patients at this stage.Non surgical root canal treatment will be performed in teeth with apical periodontitis. Periapical healing will be checked with the help of PAI Score given by Orstavik. In Cirrhosis patients MELD Score will be measured before and after treatment.
