Study Notes
Endogenous Pigmentation Examples
- An example of endogenous pigmentation in the oral mucosa includes physiological melanin deposition.
- Conditions such as Peutz-Jeghers syndrome result in pigmentation that is considered endogenous.
Conditions Linked to Oral Mucosa Pigmentation
- Physiologic pigmentation of the oral mucosa can manifest in certain populations, often linked to ethnic backgrounds.
- Melanosis of the oral mucosa is often associated with systemic conditions such as Addison's disease.
Treatment Options
- Mucocutaneous melanosis may not require treatment unless there is cosmetic concern or it is linked to an underlying disease requiring intervention.
Exogenous Pigmentation Examples
- Tattoos or amalgam restorations are prime examples of exogenous pigmentation in the oral mucosa.
Sources of Endogenous Color Change
- Melanin, blood, and various metabolic byproducts are common endogenous sources affecting mucosal color.
Causes of Exogenous Pigmentation
- Exogenous pigmentation in oral tissues can result from factors such as chronic trauma, medications, or foreign materials introduced into the oral cavity.
Contributors to Oral Mucosal Color Changes
- Various factors including systemic diseases, medications, and lifestyle choices (like smoking) can contribute to observed color changes in the oral mucosa.
Discoloration of the Dorsal Tongue
- Factors such as localized conditions, irritants, or geographical tongue can lead to discoloration of the dorsal surface of the tongue.
Diagnosis of Oral Pigmentation
- An accurate diagnosis of oral pigmentation necessitates a comprehensive clinical evaluation, including patient history, appearance characteristics, and potential biopsy if needed.
