sealants, caries, periodontal disease Flashcards
Is it legal for an RDA to place and adjust dental sealants
yes; as long as they adjust with low speed hand-piece
factors for early childhood caries consist of (4)
low income, particular ethnic groups, lack of water fluoridation and lack of public awareness
highest risk for decay in life is what age
6-15 years
indications of sealants
teeth fully erupted, opposite tooth displays same deep grooves, no proximal decay, deep pits and fissures
contraindications of sealants
incipient lesion present, proximal decay present, tooth not fully erupted, smooth occlusal surface, primary teeth close to shedding
what are the 3 sealant materials
cyanoacrylate, dimethylacrylate, methylacrylate
what are the allergens caused by sealant material
acrylates (plastic)
what do sealants with fillers require
bite adjustment
do sealants that are unfilled require a bite adjustment
no
unfilled sealant material is composed of
organic material
main purpose of sealant application
preventive and non-invasive
the marginal rider on occlusal surfaces is the
rounded, raised border on mesial and distal of posterior teeth
what factors contribute to caries formation
diet rich in fermentable carbohydrates, specific bacteria, susceptible teeth
precaution for 37% acid etch
it is an acid so it can burn the mucosa if comes in contact
shelf life of sealant material
18-36 months
purpose of caries risk test (saliva flow test)
detect number of cariogenic bacteria present in saliva
successful sealant placement is accompanied with a
low viscosity, low solubility material, and tooth material compatibility
formation of periodontal disease
initial lesion, established lesion and advanced lesion
what contributes to the formation of periodontal disease
smoking, genetics, stress
what is gingivitis associated with
plaque only
is gingivitis reversible
yes
the tissues response to plaque accumulation is
inflammation (gingivitis)
periodontitis is the
loss of attachment of soft tissues to bone
appearance of sub gingival calculus
darkened in colour
the most common type of periodontitis is
chronic periodontitis
local factors of periodontal disease
overhangs, rough margins on direct and indirect restorations
