Abstract

BACKGROUND
The major goal of dental management before and after liver transplantation is the prevention of bacteremia from an oral source that could lead to systemic infection. However dental treatment in liver transplant patients have the risk of infection and bleeding. so it is needed special dental consideration.
METHODS
42 liver transplant candidates who visited department of Advanced General Dentistry in Yonsei University College of dentistry from March 1, 2010 to February 29, 2012 were selected. The clinical data of those patients were analyzed; coagulation status such as PT, INR, aPTT, platelet count before and 6 months after liver transplantation, dental infectious foci, time interval between dental visit and operation date of liver transplantation.
RESULTS
Before liver transplant, the patient's PT and INR was prolonged, and the platelet count was lower than normal range. But 6 months later from liver transplantation, most of the figures turned into a normal range. The dental infection foci were chronic periodontitis, dental caries, chronic apical periodontitis, root rest et al but we did extraction of 6 root rest before liver transplantation and postponed other treatment after liver transplantation due to bleeding and infection risk of patients. Because of insufficient interval between dental visit and operation date, 64.3% of patients could not finish the dental treatment.
CONCLUSIONS
The patients before liver transplantation have the risk of bleeding. The treatment of those patient should be removal of only factors that can cause dental infections after transplantation and other treatment must be postponed until the stable period of the transplant that patient's condition has improved.
