Spontaneous bacterial peritonitis and soft tissue healing after tooth extraction in liver cirrhosis patients

The objective of this study was to identify the association between tooth extraction and occurrence of spontaneous bacterial peritonitis (SBP) and to assess delayed soft tissue healing of extraction sockets in patients with cirrhosis.

One hundred nineteen participants awaiting liver transplantation who required tooth extraction were included. Seven days before the surgery, the patients underwent panoramic radiography and laboratory examinations. Soft tissue healing was evaluated 7 days after the tooth extraction and medical records were checked after 21 days for development of SBP. The relationship between predictive factors and outcomes was assessed by using multiple binomial logistic regression.

One hundred ninety-five teeth were extracted, resulting in 146 alveolar wounds, in which the majority (47%) consisted of alveolar sockets of multirooted teeth. One participant was diagnosed with SBP (Escherichia coli [E. coli]) and another diagnosed with bacterascites (Streptococcus viridans [S. viridans] group), occurring 11 and 6 days after tooth extraction. Poor soft tissue healing was observed in 20 (13.7%) patients, which was correlated to 2 risk factors, that is, jaundice (P = .007, adjusted odds ratio [OR] = 4.91, 95% confidence interval [CI] = 1.56-15.47) and moderate neutropenia (P = .048, adjusted OR = 13.99, 95% CI = 1.02-192.07).

No association was found between tooth extraction and SBP in patients with cirrhosis. The delayed soft tissue healing was related to jaundice (hyperbilirubinemia) and moderate neutropenia.
