Study Notes
Buccal and Zygomatic Region
- Parotid salivary gland has a palpable part in both the buccal and zygomatic regions.
Oral Region: Lips
- Normal lip width correlates with the distance between the irises of the eyes.
- Vermillion borders are unique to humans, distinguishing the lips from surrounding skin.
Clinical Considerations with Lips
- Angular Cheilitis: Occurs at the commissures; associated with possible candida infection and nutritional deficiencies such as Vitamin B2, iron, and zinc deficiency.
- Loss of Vermilion Border: Important to document; complicates the identification of lip and skin boundaries.
Mental Region
- The mandible features a thickened posterior border of the ramus extending to the mandibular condyle.
- The condyle's articulating surface is oval, playing a crucial role in the temporomandibular joint (TMJ).
Vertical Dimension of the Face
- Facial dimensions impact esthetics and speech.
- Vertical Dimension of Occlusion (VDO):
- Small VDO commonly seen in edentulous patients indicates loss from missing teeth.
- Large VDO may prevent the patient from adequately closing their lips.
Regional Overview of the Face
- Key facial regions include frontal, orbital, nasal, infraorbital, zygomatic, buccal, oral, and mental.
Lymph Nodes
- Lymph nodes filter toxic substances from lymph to protect the bloodstream, clustered along lymph vessels.
- Enlarged or firm lymph nodes observed during exams warrant further investigation.
Case Study Highlights
- A 62-year-old male patient expresses concern over the appearance of his lower lip, requesting dental assistance after four years without visits.
- Notable medical history includes basal carcinoma; routine maintenance and full radiographic assessment are recommended.
