The periodontium is defined as
the tissues that surround, support, and attach to the teeth. These tissues include the gingiva, periodontal ligament, cementum, and alveolar bone.
Gingiva is described as
coral pink, pink, or pale pink. Color is darker when melanin pigmentation is present.
Gingiva is distinguished from the oral mucosa at the
This mucogingival junction indicates the transition from the loosely attached oral mucosa to the gingiva, which is more firmly attached to the bone by
Attached gingiva extends__________from the mucogingival junction.
coronally. (Width varies from individual to individual and from tooth to tooth)
A thin band of_______________is usually present in the posterior regions
____________________blends into the palatal gingiva without demarcation.
Palatal attached gingiva
True or False: Frenum and muscle attachments present in gingiva
Gingiva is___________or parakeratinized and is usually___________
Keratinized, stippled. Nonstippled gingiva is also observed in healthy mouths. BOARDS: ATTACHED GINGIVA IS OFTEN STIPPLED,MARGINAL GINGIVA IS NOT.
True or False (Degree of keratinization varies throughout the mouth. Palatal gingiva is the least keratinized. Cheek mucosa is the most keratinized)
The first statement is true and the second two are false. The palatal gingiva is the most keratinized and the cheek gingiva is the least keratinized.
The edge of the gingiva next to the teeth, which is referred to as the
Area above it= anatomic portion of tooth; Area below (apical) to it= anatomic root of tooth (link is for image)
The ________surrounds the tooth and creates a cuff or collar of gingiva that extends coronally approximately 1.5 mm.
free gingiva (the free gingiva on the buccal and lingual surfaces is described as knife-edged)
( True or false)The surface of the free gingiva next to the tooth forms the gingival wall of the sulcus.
The free gingiva is distinguished from the attached gingiva by a:
A. Mucogingival junction
C. Free gingival groove
D. Junctional epithelium
C. Free Gingival groove (this groove varies from tooth to tooth)
The papillae, aka ________________ are gingivae that fill embrasures
proximal spaces below the contact areas of the teeth.
When the papilla is broad, often between posterior teeth, a nonkeratinized area called the__________is present
