"Liver clot"-A rare periodontal postsurgical complication.

Bleeding is a common sequela of oral and periodontal surgery. Generally, bleeding is self-limiting. Following traumatic injury or surgical procedures, hemorrhage can range from a minor leakage or oozing at the site, to extensive bleeding leading to complete exsanguinations. Significant postsurgical hemorrhage following periodontal surgery is uncommon due to the primary closure of the soft tissues. This case report describes the unique formation of a "liver clot" or "currant jelly clot" following periodontal flap surgery. The likelihood of this may be attributed to many factors, like infection, intrinsic trauma, presence of foreign bodies like splinter of bone, a fleck of enamel, or a piece of dental restorative dressing material that may cause repeated, delayed organization of blood coagulum.

Hepatitis in dental practice - A study conducted on 1498 patients

All the patients were operated under general anesthesia and were screened for hepatitis B and C virus. This is the retrospective study conducted from September 2002 to December 2004. There were 1498 patients. Out of these, 44 were diagnosed as positive for the viral pathology. Some infected patients presented with a known history of jaundice, blood transfusions, major and minor dental surgeries in the past. The percentage of patients positive for HBsAg and HCVAb was 1.66 and 1.26 respectively.
