Oral Health and Aging Flashcards
Lec 9 part 1
What are the structures of the oral cavity?
lips, teeth, tongue, hard palate, soft palate, floor of mouth, tonsils, uvula, retromolar trigone, buccul mucosa
What is edentulous?
means lacking teeth
What is dental restoration?
surgeries replacing of fixing teeth. more common in men.
What is the structure of the tooth?
enamel, dentin, pulp cavity, root canal, blood vessels and nerves,
What are root caries?
when bacteria gets to the root of tooth which can occur bc of gum recession or pockets in gum.
What are coronal dental caries?
bacteria cavitates and penetrates through enamel into the dentin of a tooth.
Why are dental caries bad?
dont want bacteria getting to root bc it can then get into blood stream.
What is poor health related to?
diabetes, respiratoy diseases, heart disease and stroke.
What is the connection btwn oral disease and systemic disease?
Bacterial biofilm which is clusters of bacteria that stick to surfaces and each other and are embedded in a self produced matrix. continually grows in mouth. plaque hardens and becomes tartar/calculus and cannot be brushed off which causes gum disease, bad breath, and cavities. so plaque needs to be removed every day to maintain oral health.
What is the link btwn periodontal disease and respiratory diseases?
aspiration of dental plaque causes aspirational pneumonia.
what is the link btwn heart disease/stroke and periodontal disease?
adds to inflammatory burden, so have elevated immune response.
What are the common traits btwn diabetes and periodontal disease?
multi-factorial disease; genetic makers, and lifestyle behaviours. pathogenic commonalities, ability of bodys immune system to effectively mount a response to insult.
how does saliva and sugar affect dental caries?
less saliva= less cleansing and buffering action, makes dental plaque grow rapidly. a higher sugar lvl in salvia is food for plaque.
What are the determinants of chewing dysfxn?
low oral health, no dental insurance, edentulous, OAs, lack of regular source of dental care.
What is bacterial dental biofilm?
biofilm is nidus for bacteria, so its a place that multiplies bacteria. bacteria is plaque which becomes calculus and hardens so it cant be brushed off. when host resistance is challenged can lead to periodontal disease and tooth decay.
What are the causes of tooth decay?
the tooth, plaque bacteria so bacterial biofilm increases rate of calculus, and carbohydrates/sugars which are cariogenic so promote growth of bacteria.
What is periodontal (gum) disease?
preventable infection that is caused by build up of bacteria into calculus that destroys bone and causes tooth loss. signs are; bleeding, pus, bad breath, itchy, bad taste, loose teeth
What is tooth loss associated with?
age 75 and 80, onset of disability, and age 70+ higher risk of mortality.
Why do ppl become edentulous?
lack of funds /insurance for health care, nutritional changes, chronic diseases that affect fxnl ability, lack of access to dental care.
What is basic mouth care?
brushing for at least 3 min with soft bristles brush. brushing tongue. flossing. using mouthwash with fluoride in it but not too much alcohol bc it dries out the mouth.
What is dry mouth?
can be caused by things out of control like meds. want to keep hydrated to keep clean and less bacteria. monitor and adapt meds. thorough daily mouth care, avoid sugar gum and candy, use fluoride, get regular oral examinations.
What is oral frailty?
when theres challenges to the immune system which make you more susceptible to bacteria growth.
What are monthly oral screenings?
when check up on mouth regularly, 2 week rule is when if theres smthn like a cut or bump keep an eye on it and if it doesnt go away in 2 wks go see a dentist.
What is the value of good oral hygiene?
confidence and attractiveness (smile), close relationships and communication (no bad breath), enjoying full and varied diet, expense of treatment less.
Affects of aging and oral health?
meds, chronic illnesses, having funds to get dental care, do they have dentures, living in ltc need others to clean for them so depending on others to keep good oral health.
Requiring assistance means?
caregiver needs to be trained so htat theyre knowledgable and skilled. eliminates repulsion. resident more likely to cooperate, need supplies, is it a priority or do they have time.
