Study Notes
Learning Objectives
- Understand epidemiology, manifestations, complications, and management of hepatology disorders affecting dentistry.
- Develop skills to interpret clinical manifestations and investigations to create reasonable diagnosis and evidence-based management plans.
- Recognize emergency situations in patients with hepatology disorders to ensure proper management and homeostasis.
Liver Diseases of Dental Interest
Viral Hepatitis
- Inflammation of the liver caused by viruses leading to acute or chronic forms.
- Types include Hepatitis A, B, C, D, and E, plus other viruses like EBV and HSV.
- Hepatitis A: RNA virus transmitted via the faecal-oral route with no carrier state; 15-50 days incubation; lifelong immunity after infection.
- Hepatitis B: DNA virus transmitted sexually, percutaneously, and perinatally; 30-180 days incubation; carries a state; lifelong immunity with vaccination.
- Hepatitis C: RNA virus spread percutaneously; 15-160 days incubation; high carrier rate (50-80%); no vaccine available.
- Hepatitis D: Defective RNA virus needing Hepatitis B to infect; similar risk groups and incubation as B.
- Hepatitis E: Defective RNA virus spread through faecal-oral route; 15-64 days incubation; no carrier state or prophylaxis.
- Clinical features include flu-like symptoms, jaundice, abdominal pain, and hepatomegaly. Post recovery hepatomegaly may persist for months.
- In dentistry, jaundice of the mucosa is observable during the icteric phase; precautions are vital as all patients are potentially infectious.
Alcoholic Liver Disease (ALD)
- Resulting from chronic alcohol abuse, manifesting as fatty liver, alcoholic hepatitis, or cirrhosis.
- Symptoms include jaundice, ascites, and various neurological signs like slurred speech or memory issues.
- Diagnosis involves history-taking, clinical examination, and specific laboratory tests.
- Dental care requires physician consultation, avoidance of hepatotoxic drugs, and attention to potential bleeding issues.
Liver Cirrhosis
- Chronic liver disease characterized by fibrosis and the formation of nodules leading to loss of function; often irreversible.
- Common causes: viral infections (HBV, HCV), alcohol, drug-induced liver injury.
- Symptoms include jaundice, ascites, and signs of liver failure such as spider nevi and oedema.
- Diagnosis confirmed through liver biopsy and blood tests; management focuses on treating complications and potential liver transplant.
Liver Cancer (Hepatocellular Carcinoma)
- Malignancy of the liver, often linked to chronic HBV or HCV infections, or cirrhosis.
- Symptoms: abdominal pain, weight loss, ascites, jaundice; notable male to female ratio of 3:1.
- Diagnosis involves liver biopsy and alpha-fetoprotein levels; management typically requires surgical intervention or chemotherapy.
Jaundice
- Yellow discoloration from elevated bilirubin levels; categorized into prehepatic, hepatic, and cholestatic jaundice.
- Symptoms include yellowing of skin and sclera with varying underlying causes such as liver disease or biliary obstruction.
- Clinical signs include spider nevi, ascites, and bleeding tendencies; in the dental context, awareness of bleeding risks and infectious controls is crucial.
Ascites
- Accumulation of fluid in the peritoneal cavity linked primarily to liver cirrhosis, but also other conditions like cardiac failure.
- Symptoms include abdominal discomfort, increasing girth, and potential shortness of breath.
- No specific oral manifestations; however, dental treatment considerations must include the patient’s overall health and potential need for consultations.
