Chapter 1-36 Complete Guide .
periodontium - ANSWER: structures that surround, support, and are attached to the
teeth
what 2 groups can the periodontium be divided into? - ANSWER: 1. gingival unit
2. attachement unit
what parts are included in the gingival unit of the periodontium? - ANSWER: -free
gingiva
-attached gingiva
-alveolar mucosa
what is gingiva composed of? - ANSWER: very dense mucosa called MASTICATORY
MUCOSA and has thick epithelial covering and keratinized cells
what is the underlying mucosa of the gingiva composed of? - ANSWER: dense
collagen fibers
where else in the oral cavity is masticatory mucosa found besides the gingiva? -
ANSWER: the hard palate (designed to withstand the trauma to which is subjected in
grinding food)
lining mucosa - ANSWER: -thin, non-keratinized and freely moveable
-composed of loose connective tissue and muscle fibers
-includes: buccal mucosa, ventral side of tongue etc
what kind of appearance/texture does gingiva have? - ANSWER: stippled surface
what kind of fibers are in lining mucosa? - ANSWER: collagenous and elastic
what kind of fibers are found in masticatory mucosa? - ANSWER: collagenous
free gingiva - ANSWER: -extends from the gingival margin to the base of the gingival
sulcus
-forms a collar, which is separated from the tooth by the gingival sulcus
-free gingival margin around a fully erupted tooth is about 0.5-2mm coronal to the
CEJ
if a gingival sulus is healthy, what will the depth not exceed? - ANSWER: 3mm
gingival papilla (interdental papilla) - ANSWER: part of the free gingiva that is the
triangular shaped gingiva between the teeth
, if the gingival papilla is unhealthy, what will it look like? - ANSWER: inflammation
evident by red color, puffy appearance and blunted apex
for the gingival papilla, the adjacent tooth determines its shape by what 3 things? -
ANSWER: 1. location of the CONTACT AREA of adjacent tooth
2. shape of interproximal surfaces
3. CEJ of adjacent tooth
gingival sulcus - ANSWER: -space between free gingiva and the tooth
-inner portion lined with non-keratinized epithelium
-outer portion covered with keratinized epithelium
-attached gingiva begins at the base of the gingival sulcus
-the gingival groove is often the base of the sulcus on the outer side of gingiva
attached gingiva - ANSWER: -extends from base of the sulcus to the mucogingival
junction
-keratinized, stratified squamous epithelium
-attached to bone and cementum by collagenous fibers
-stippled texture caused by rete peg formation
-light to dark pink in color
rete peg formation - ANSWER: the irregular binding of epithelium to the bone by
collagen fibers (causes depressions/dimples where epithelium is pulled tight to the
bone)
how is gingiva connected? - ANSWER: -connected to tooth buccally and lingually
(proximal sides) by collagenous fibers formed by fibroblasts (connective tissue)
what is the name of the fibers embedded into the cementum? - ANSWER: sharpey's
fibers (extend from cementum to papillary area of the gingiva)
some fibers curve towards the mucosa of the free gingiva and interlace with one
another and some fibers pass directly across from cementum to gingiva, what is the
function of these fibers? - ANSWER: -to keep the gingiva closely attached to tooth
surface
-these fibers prevent free gingiva from peeling away from the tooth and keep the
ATTACHED GINGIVA FIRMLY ATTACHED
-prevent apical migration of the epithelium attachment/gingival recession
proximally fibers arise from cementum but from a higher level, why? - ANSWER:
because of the curvature of the CEJ interproximally
what does the curvature of the CEJ allow for in terms of fibers? - ANSWER: allows for
more room for cementum to attach to gingiva
