Which component is not found in Carnoy's solution?

• A. Chloroform
• B. Acetone
• C. Glacial acetic acid
• D. Absolute alcohol

Answer: (B)

Carnoy's solution is a fixative commonly used in surgical pathology, particularly for the preservation of tissue specimens. It is composed of three main components: ethanol (absolute alcohol), chloroform, and glacial acetic acid. Each of these components plays a specific role in fixing tissues. Ethanol dehydrates the tissues and preserves structural integrity, chloroform helps in clearing and further stiffening the tissues, and glacial acetic acid assists in preserving nucleic acids and cellular morphology. Acetone is not a part of Carnoy's solution. While acetone is used as a fixative in some protocols, it does not contribute to the specific fixation properties that Carnoy's solution is designed to achieve. Therefore, the presence of acetone in this question correctly identifies it as the component not found in Carnoy's solution. Understanding the specific ingredients and their functions in fixation solutions is crucial for proper preservation and examination of tissues in oral and maxillofacial surgery and related fields.
