Study Notes
Learning Objectives
- Recognize the epidemiology, manifestations, complications, and management of hepatological disorders with dental implications.
- Develop skills to interpret clinical signs and laboratory results to establish diagnoses.
- Formulate evidence-based management plans for hepatological disorders impacting dental health.
- Identify emergency situations and create comprehensive management plans to maintain patient homeostasis.
Liver Diseases of Dental Interest
Viral Hepatitis
- Involves inflammation of the liver caused by various viruses, including Hepatitis A, B, C, D, and E, along with other viruses like EBV, HSV, and CMV.
- Hepatitis A:
- An RNA virus transmitted via the faecal-oral route.
- No carrier state exists; prophylaxis includes immunoglobulin and vaccination.
- Immunity likely lasts for life after infection.
- Hepatitis B:
- A DNA virus spread through percutaneous, sexual, or perinatal routes.
- Incubation lasts 30-180 days; a carrier state is possible.
- Prophylaxis involves Hepatitis B immunoglobulin and a vaccination.
- Hepatitis C:
- An RNA virus transmitted through blood and occasionally sexually.
- Incubation is 15-160 days, with a high carrier rate (50-80%).
- No vaccine or prophylaxis is available.
- Hepatitis D:
- Defective RNA virus that co-infects with Hepatitis B virus.
- No prophylaxis available; the HBV vaccine provides some immunity.
- Hepatitis E:
- Defective RNA virus spread via the faecal-oral route.
- Risk for travelers in endemic areas; no carrier state or prophylaxis.
- Clinical features often include flu-like symptoms, transitioning through preicteric, icteric, and posticteric phases.
- Oral manifestations: jaundice may appear in the oral mucosa. Patients known to be carriers of HBV, HCV, or HDV should be treated with caution; all are considered potentially infectious.
Alcoholic Liver Disease (ALD)
- Refers to liver injury resulting from alcohol abuse, classified into fatty liver, alcoholic hepatitis, and cirrhosis.
- Symptoms of ALD include jaundice, fatigue, ascites, and various hematological abnormalities.
- Diagnosis often includes history-taking, breath analysis, and systemic examinations.
- Dental management involves physician consultation, screening for potential complications, and informed consent.
Liver Cirrhosis
- Chronic liver disease marked by fibrosis and loss of liver function due to various causes, including infections (Hepatitis B and C), alcoholism, and drug exposure.
- Symptoms: lethargy, itching, jaundice, hepatomegaly, splenomegaly, and ascites.
- Early diagnosis uses liver biopsy, blood tests, and endoscopy to detect esophageal varices.
- Management is typically palliative with liver transplant being a consideration in advanced cases.
Liver Cancer (Hepatocellular Carcinoma)
- A malignant liver tumor, commonly developed from chronic hepatitis or cirrhosis.
- Symptoms include abdominal pain, weight loss, jaundice, and hepatomegaly.
- Diagnosis relies on liver biopsy, imaging, and serological markers like alpha-fetoprotein.
- Management strategies may include resection, transplantation, or chemotherapy.
Jaundice
- Characterized by yellow discoloration due to elevated bilirubin levels.
- Causes include hemolysis, liver disease, and biliary obstruction.
- Symptoms: yellowing of skin and sclera; in prehepatic jaundice, family history and drug exposure are important.
- Management focuses on identifying and addressing the underlying cause.
Ascites
- Defined as the accumulation of excess fluid in the peritoneal cavity, often arising from cirrhosis or malignancies.
- Symptoms include abdominal discomfort and increase in girth.
- Dental considerations include avoiding hepatotoxic substances and ensuring medical evaluations prior to any procedures.
