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.

Objectives: The purpose of the study is to investigate the relationship between oral health status and body mass index (BMI) in adults over 65 years old. Methods: The study subjects were 4,550 adults over 65 years old from the 5th Korea National Health and Nutrition Examination Survey(KNHANES V) in 2010-2012. Mastication-related oral health status included the number of remaining teeth, and mean number of decayed, missing, and filled permanent teeth(DMFT). Body mass index(BMI, $kg/m^2$) was categorized as underweight(<18.5), normal weight (18.5-22.9), overweight(23.0-24.9), and obese(${\geq}25.0$). Multinomial logistic regression analysis was performed to examine the association of BMI categories with the number of remaining teeth and DMFT. Results: The mean number of DMFT was highest($13.0{\pm}0.7$) in the underweight group and lowest($8.8{\pm}0.3$) in the obese group. Those having less favorable masticatory ability, and fewer number of remaining teeth and no prosthesis, tended to be underweight. Those having a higher number of remaining teeth and prosthetic teeth tended to be overweight or obese. In the multinomial logistic regression analysis, compared with those having 20 or more remaining teeth, including prosthetic teeth, those having less than 20 remaining teeth and no prosthesis had 4.48 times higher odds ratio of being underweight. DMFT was positively associated with underweight, while negatively associated with overweight or obesity. Conclusions: The masticatory ability and dental caries prevention maintained the healthy body weight in adults of old age.
