Complete Solutions 100% Correct
What are the tissues of the periodontium - ANSWER Gingiva
Pdl
Alveolar bone
Cementum
What are the main functions of the PDL - ANSWER Shock absorber
Transmits occlusal forces
Attaches teeth to bone
Supplies nutrients to the perio structures
Transmits sensations
What are the fibers called that attach tooth to bone - ANSWER Sharpey's fibers
What are the principle fiber groups of the pdl - ANSWER Transeptal - interproximal from
tooth to tooth
Alveolar- apical to junctional epithelium. Cementum to alveolar
Oblique fibers - largest and most abundant. From cementum coronal lay to bone
--this withstands masticatory stresses
Horizontal fibers- right angles at the long axis of the tooth
, Apical fibers - extend apical from cementum to the base of the tooth's socket.
Interradicular fibers - only on multiroot end teeth
What is the most predominant cell in the PDL ANSWER Fibroblasts
What cells build bone and what cells resorb bone - ANSWER Odontoblasts - build
Odontoblasts- resorb
What cells form cementum - ANSWER Cementoblasts
What are some of the ways dental plaque can induce gingival diseases - ANSWER By
plaque alone
By medications and nutrition
What are the ways that gingival disease can be initiated that are not plaque induced -
ANSWER Viral or fungal or genetic origin
Gingival manifestation of systemic conditions
Traumatic lesion
Foreign body reactions
What are some specific causes of gingival inflammation - ANSWER Open contacts
Subgingival margins of restorations
