Landmarks Section added by Heidi Emmerling, RDH, PhD
63
Lips
64
Wet Line The wet line is the junction between vermillion border and the mucosa of the lip.
65
Wet Line
66
Vermillion Border The vermillion borders of the upper (A) and lower (B) lips are indicated by the arrows.
68
Labial Mucosa The labial mucosae are the mucosal surfaces of the upper and lower lips. Here you see the lower labial mucosa.
70
Buccal Mucosa This is a good picture of most of the right buccal mucosa of this patient. It is the inner lining of the right cheek.
72
Parotid Papilla The parotid papilla or the opening of Stenson's duct (arrow) often appears as a nodule on the buccal mucosa. Don't confuse it with a lipoma or fibroma and cut it off.
74
Hard Palate

Incisive Papilla

78
Ruggae The rugae (arrows) are frequent sites of injury.
80
Soft Palate
81
Median Palatal Raphae The palatine raphe (arrows) is more prominent in some people than in others. It is very easily palpated in all patients.
83
Fovea Palatinae At the posterior end of the hard palate, there are frequently two small depressions, the fovea palatinae. This demarcates the imaginary line of where the hard palate ends and the soft palate begins
86
Uvula The uvula (arrow) is a prominant landmark at the opening of the oropharynx.
88
Oropharynx The opening to the oropharynx (OP) is outlined by the broken line. The soft palate (SP) is more anterior.
89
The glossopalatine arch is designate G, and the pharyngopalatine arch is designated P. These are also called the anterior pillar (G) and the posterior pillar (P) of the fauces. Between them is the tonsillar niche (N).
90
Enlarged tonsils
93
Tongue
94
Filiform These are the most numerous papillae, the filiform papillae (arrows).
96
Fungiform Bright red, larger, have taste buds Yum!
98
Circumvallate Papilla
large on posterior of dorsum of tongue 8-12 in number
100
Foliate papilla lateral-posterior border
These are the foliate papillae (arrows). These papillae are particularly subject to trauma from biting during mastication. When they get traumatized, they are very painful and may even become infected and cause cervical lymphadenopathy
102
Normal frenum
103
Ankylogossia This is the gross appearance of the tongue when patient was asked: "Stick out your tongue. "Note the classic symptom of a bifid or bilobed lingual apex with a corresponding midline "cleft" or septal limitation.
105
"Now pull your tongue back into your mouth as far as you can."
The extremely short lingual frenulum is attached high on the gingival margin and the lingual attachment is far more superior and anterior on the tongue than normal. The point where the frenulum exits the tongue tip is bordered by filiform and fungiform papillae (taste buds). The frenulum is blanched white from the ischemia caused by the tight pull on the lingual apex during tongue retraction.
107
Manual elevation of the lingual apex by the examiner.
109
"Open your mouth wide and show me your tongue."
Note the hypoplastic development of the lingual apex in contrast to the bulk of the more posterior blade of the tongue behind it (demarcated by the cone-like shape and more dense distribution of fungiform papillae on the apex).
111
Lingual Varicosity Enlarged, dilated bluish-purple blebs on the ventral surface of the tongue Usually found in older adults(2/3 over 60)
113
Periodontium (duh)
115
alveolar mucosa Unattached gingiva =alveolar mucosa
119
interdental groove a linear, vertical depression on the surface of the interdental papillae; it functions as a sluiceway for the egress of food from the interproximal areas.
