swollen and bleeding gums, slow wound healing, fatigue, depression and poor digestion can be the result of
vitamin c deficiency
a major factor in determining the carcinogenicity of a carbohydrate is

minerals, vitamins, fats, proteins and carbohydrates
a well balanced mixture of all 8 essential amino acids is the definition of a
complete protein
a good source of vitamin d is
fish, sunlight, butter
saliva flow serves what function(s)
speeds the clearance of food from the mouth, aids in remineralization of the teeth, delivers fluoride to the teeth
what is the concept of preventative dentistry
goal is to help an individual achieve and maintain an optimal oral health throughout their lives
dental assistants role in preventative dentistry is to
educate and motivate patients to maintain good oral health
what is one of the biggest barriers in which rdas overcome and should be aware of their behaviour and expressions while dealing with different patients
language barrier
tooth deposit order
acquired pellicle, plaque, material alba, food debris, calculus
materia alba can be removed with __ ,whereas ___ cannot
a water spray or oral irrigator; plaque
what is acquired pellicle
a thin acellular colourless transparent bacteria free film that forms on the teeth within minutes after cleaning
acquired pellicle is composed of
glycoproteins from saliva aka mucin
pros of acquired pellicle
keeps surfaces moist and acts as a barrier against acids produced by plaque
the first stage in biofilm formation is the
acquired pellicle
acids released from dental plaque lead to ___ of the adjacent tooth surface leading to caries/decay
demineralization
plaque is soft and can be easily removed by
brushing flossing
if plaque is not removed thoroughly and effectively at least once within 24 hours is can cause
gingivitis
calculus (tartar) refers to calcified deposits on the teeth formed by
mineralization of dental plaque
calculus frequently occurs on
lingual of mand. anteriors and buccal of max. molars
what is the cause of periodontal disease
plaque
if left undisturbed plaque can cause
destruction of epithelial attachment, pocket formation, bone destruction
periodontal disease is described in terms of
severity and loss of attachment
dental caries is a bacterial infection caused by specific bacteria which is
streptococcus mutane and lactobacilli
plaque bacteria + sugar/starch =
acid
the first sign of demineralization is a small
white spot/ white fleck
the teeth that benefit the most from optimum level of fluoride are
the ones still developing and newly erupted ones
2% sodium fluoride has a ___ pH and is safe for
neutral; safe for existing restorations
1.23% acidulated phosphate fluoride pH? should not be used on?
3.0-3.5; restorations
stannous fluoride can cause
staining of the teeth
disclosing agent contraindications
do not apply to tooth coloured restorations, do not apply before a sealant to be placed
toothbrushing technique recommended for patients with periodontal pockets and gingival inflammation
modified stillmans
when should a patient floss
before brushing
halitosis is
bad breath
coronal polishing removes plaque and
extrinsic stains
carbohydrates are the
chief source of energy and bulk
a co plate protein supports
life and normal growth
lipids (fats) provide
essential fatty acid, cushions main body organs, provides heat insulation, provides concentrated energy, makes food taste better, act as carrier of fat-soluble vitamins
HDL = ___ cholesterol
good cholesterol
deficiency of vitamin B causes
anemia and angular chelitis
