Oral Pathology: Lesion Terminologies | Full Lecture 2023

TL;DR

This video explains the 13 different classifications of oral pathology lesions, including macule, patch, erosion, ulcer, fisher, papule, plaque, nodule, vesicle, pustule, cyst, and tumor.

Transcript

hey what about my two doctors and doctors is welcome to another video at the tooth Factory today we're going to be continuing with our oral pathology series of important terminologies of lesions now we need to understand that before we get into the depths of oral pathology specific lesions say for example dentiger assist the infamous lesion of worl...

Key Insights

• 🪸 Understanding lesion classifications in oral pathology is crucial for accurate diagnosis and treatment.
• ⚾ Lesions can be categorized into macule, patch, erosion, ulcer, fisher, papule, plaque, nodule, vesicle, pustule, cyst, and tumor based on their specific characteristics and size.
• 🖐️ Biopsies play a vital role in transitioning from a differential diagnosis to a definitive diagnosis.
• 🌥️ Incisional biopsies are used for large lesions or when malignancy is suspected, while excisional biopsies are performed for vascular lesions, definitive malignancies, or when removing the entire lesion.
• ⌛ No treatment-oriented biopsy is used when a lesion is suspected to be benign, and observation is preferred to monitor any changes over time.

Questions & Answers

Q: What is the difference between erosion and ulcer?

Erosion is a break in the epithelium above the basal layer, while an ulcer is the same type of break but extends into the basal layer and enters the connective tissue.

Q: How is a nodule different from a papule?

Both nodules and papules are raised lesions, but nodules are deeper and more than one centimeter wide, while papules are less than one centimeter in diameter.

Q: What defines a plaque as a classification?

A plaque is a raised lesion, more than one centimeter in diameter, but it does not have a vertical dimension like nodules or papules.

Q: How is a cyst different from a pseudocyst?

A cyst is a cavity lined by epithelium and contains fluid, air, or other substances. However, if the lining is not epithelium, it is called a pseudocyst.

Summary & Key Takeaways

• The video introduces the importance of understanding lesion classifications in oral pathology to better identify specific lesions in future lectures.

• It discusses the 13 main classifications of oral pathology lesions, such as macule, patch, erosion, ulcer, fisher, papule, plaque, nodule, vesicle, pustule, cyst, and tumor.

• It explains the distinguishing features and size criteria of each classification and emphasizes the importance of histological analysis for definitive diagnosis.
