Risk factors for Dental Diseases Flashcards
How is plaque a risk factor for caries?
plaque bacteria which has a rapid use of sugars and metabolises them at extreme pHs cause caries,
How is diet a risk factor for caries?
when sugar was less available, caries incident was much lower, sugar is food for bacteria in plaque, produces acid that demineralises tooth- dynamic process
Miller chemicoparasitic study to show caries and diet link
incubate food with sugar and saliva to see acid formation, concluded starch was most damaging to teeth
Vipeholm study to show cariesa and diet link
diet low in sugar = low caries incident. now bc of ethics cant change diet to cause caries, frequency and timing also very important for caries incidents.
What is the most susceptible tooth surface?
any surface can be it matters more on accumulation of plaque like in pits and fissures, next to gums
How is low fluoride exposure a risk factor for caries?
fluoride enhances remineralisation process
How is low saliva a risk factor for caries?
it aids remineralisation and has a buffering capacity so less saliva causes caries to spread more
How is plaque a risk factor for periodontal disease?
Bacteria products in plaque cause cells in adjacent tissues to produce inflammatory response so fluids fill up in gums, appear red/swollen, cells come to site and release toxins
What happens if plaque is left?
Cells keep releasing toxins, inflammation beyond gums, bone is lost, teeth become loose and teeth are lost
How is smoking a risk factor for periodontal disease?
Impairs blood vessels and impacts inflammatory and immune response,
affects biofilm and impairs wound healing, causes increased susceptibility
How is diet a risk factor for periodontal disease?
Not eating right nutrients can cause a weaker immune response against plaque, also increases amount of plaque
How is diabetes a risk factor for periodontal disease?
bc of less insulin risk of disease is 3x bigger
causes accelerated bone loss, two way relationship perio increases diabetic complications while diabetes increases perio disease
