LP4 Risk Factors Flashcards
(29 cards)
what increases the probability of the occurrence of a disease?
a risk factor
why use a caries risk assessment with your patients?
- info gathered can be a great way to individualize the patients education
- used as a tool to educate patients about oral conditions/issues in general and make them aware of own specific conditions
- create opportunity to address how caries are developed and transmitted
- track recommendations/modifications
- used to associate the patients current habits or behaviors to their caries status: its that direct link between behavior and existing caries
- can be a source of reward for behavior modification, recognition of the positive changes will support continued improvement
4 risk factors that contribute to caries and examples
- habits: sucking on a lemon drop after every meal
- behaviors: brushing daily with a hard tooth brush and baking soda
- lifestyles: how the patient lives
- conditions and situations: homeless, or no hygiene products
what are some components of social history?
gender, age, education level, family history, stress level, employment status
what are some components of medical history
medications, health status, health conditions, salivary flow, physical or emotional concerns, history of drug use,
components of fluoride use
water, rinses, dentifrices, amount/frequency of exposure
components of dietary habits
what, when, where do they eat, frequency and amount of sugar items and detergent food items, diet status, and knowledge
components of biofilm control
PCR scores, current home care practices
components of clinical and oral findings
IEOE, PA, X-rays, Dental Charting
characteristics of low caries risk level
- no new incipient caries
- regular dental visits
- good oral hygiene
- few restorations
- low PCR score
- good dexterity
- fluoride exposure
characteristics of moderate, high and extreme caries risk level
- history of numerous or severe cavities
- deep pits and fissures
- decreased salivary flow
- poor oral hygiene
- inadequate fluoride exposure
- irregular dental visits
- medically compromised
- xerostomia
- poor diet
- dental appliances
- multiple restorations
- uses tobacco
- family history generally poor
what is a dental index
assessment tool in numeric value
what is a DMFT
irreversible index used to measure past and present caries experience of a population with permanent teeth
great for ____ term and _____ studies
short term
longitudinal studies
what does DMFT stand for?
decayed, missing, and filled teeth
“D” components
- decayed
- indicated active caries
- represents: treatment needs
“M” components
- missing
- indicated that a tooth is no longer in the mouth as a result of caries
- represents:prosthetic needs such as bridge, implant or denture
“F” components
- filled
- indicated that caries occured but now arrested
- represents: level of success of therapeutic program such as amalgam or composite/crown
“T” components
- teeth
- permanent dentition
how many teeth is the DMFT based on?
28 teeth
if a tooth has a restoration on it already but also has decay, where does it get recorded as?
in the decay column
to have existence of caries you must have one:
- lesion is clinically visible
- explorer can penetrate into soft material
- discoloration or loss of enamel
- explorer tip in a pit/fissure resists removal after moderate to firm pressure on insertion
what are some limitations to DMFT
- values aren’t related to the number of teeth at risk
- can be misleading in children whose teeth have been lost due to orthodontia
- can overestimate caries experience in teeth which “preventative” fillings have been placed
- is of little use in studies of root caries
- cannot account for sealed teeth
what teeth are not counted when calculating DMFT
- 3rd molars
- non erupted teeth
- congenitally missing and supernumerary teeth
- teeth removed for reasons other than dental caries
- primary teeth retained with the permanent successor present
