Periodontology - Exam 1 Questions and Answers Already Passed Latest Update 2025-2026
the functional system of tissues that surrounds the teeth and attaches them to the bone. - Answers
Periodontium
structure that provides a tissue seal around the cervical portion of the tooth, holds tissue against the
tooth during mastication & is composed of a thin layer of epithelium and an underlying core of
connective tissue - Answers gingiva
what are the 4 anatomic areas of the gingiva? - Answers free gingiva
gingival sulcus
interdental gingiva
attached gingiva
structure located coronal to the CEJ, surrounds the tooth like a turtleneck, fits snugly around the tooth
but is not attached, can be gently pulled away with a probe, forms soft tissue wall of the gingival sulcus. -
Answers free gingiva
thin, rounded edge where the free gingiva meets the tooth. - Answers gingival margin
the space between the free gingiva and the tooth surface - Answers gingival sulcus
forms the base of the gingival sulcus - Answers junctional epithelium
the portion of gingiva that fills the area between two adjacent teeth apical to the contact area, &
consists of two interdental papillae; facial and lingual - Answers interdental gingiva
a valley-like depression in the interdental gingiva that lies directly apical to the contract area - Answers
col
portion of the gingiva located between the free gingiva & the alveolar mucosa. prevents free gingiva
from being pulled away from the tooth when tension is applied to alveolar mucosa, allows gingival tissue
to withstand mechanical forces created during chewing, speaking & toothbrushing - Answers attached
gingiva
in what regions is the attached gingiva widest? - Answers incisor & molar regions
in what regions is the attached gingiva narrowest - Answers premolar regions
dimpled appearance on the surface of the attached gingiva caused by the connective tissue fibers that
attach the gingival tissue to the cementum & bone - Answers stippling
thin layer of hard, mineralized tissue that covers the surface of the root, light yellow in color, overlies
the dentin, bonelike but more resistant to resorption than bone, & it does not have its own blood or
nutrient supply - Answers cementum
, soft connective tissue that covers the root of the tooth and attaches to the bone of the tooth socket. -
Answers PDL (periodontal ligament)
structure that surrounds and supports the roots of the teeth in the jaws. - Answers alveolar bone
what are the 4 layers of the alveolar bone? - Answers alveolar bone proper (cribriform plate)
cortical bone
cancellous bone (spongy bone)
Periosteum
bony socket that houses the root of the tooth - Answers alveolus
thin layer of bone that lines the socket to surround the root of tooth, appears to have large pores where
blood vessels connect structures, ends of the PDL fibers are embedded here - Answers alveolar bone
proper
forms the hard outer wall of the jaws on the facial and lingual aspects, surrounds the alveolar bone
proper and gives support to the socket - Answers cortical bone
the most coronal portion of the cortical bone - Answers alveolar crest
spongy, lattice-like bone filler between the cortical bone and the alveolar bone. oriented around the
tooth to form support for the alveolar bone proper - Answers cancellous bone
these tissues make up the outer surface of the body & line the body cavities such as the mouth,
stomach, & intestines. - Answers epithelial tissues
these tissues fill the space between the tissues and organs in the body - Answers connective tissues
both epithelial & connective tissues are comprised of __________ & __________ - Answers cells &
extracellular matrix
the smallest structural unit of living matter - Answers cells
a gel-like substance containing interwoven protein fibers that surround the most cells - Answers
extracellular matrix
tissue that makes up the skin, lines the body cavities such as the mouth, stomach, and intestines. -
Answers epithelial tissue
epithelial tissue is characterized by ________ cells & ________ extracellular matrix - Answers plentiful,
sparse
the thin mat of extracellular tissue in epithelial tissue - Answers basal lamina
