What is an incisional biopsy?

Surgical excision of a lesion
Diagnosis of dental diseases
Excision of wedge-shaped tissue for diagnosis
Defective tissue development

The correct answer is: Excision of wedge-shaped tissue for diagnosis

An incisional biopsy involves the surgical removal of a small section of a lesion, which typically allows for the examination and diagnosis of abnormal tissue. This technique is particularly useful when dealing with larger lesions that cannot be entirely removed safely or when preserving surrounding tissue is necessary. The biopsy sample is sent for histopathological analysis to determine the nature of the lesion, helping to identify conditions such as cancer, infections, or other pathologies, making it a key tool in the diagnostic process for dental and oral diseases. The other choices do not accurately describe an incisional biopsy. Surgical excision of a lesion would typically involve removing the entire lesion, rather than a portion of it. While diagnosis of dental diseases is a broader term that could encompass several diagnostic methods, it does not specifically relate to the act of performing a biopsy. Lastly, defective tissue development refers to abnormal tissue formation but does not describe a procedure or its purpose. Therefore, choosing the option that states excision of wedge-shaped tissue for diagnosis captures the essence of what an incisional biopsy entails.
