Q

3 stages to managing dental neglect

A
  1. preventative dental team mx = single unit approach, set targets, keep records & monitor process
  2. preventative multiagency approach = liaise with other HCPs, child may be subject to common framework assessment, agree joint plan of action, r/v at set intervals, letter to health visitor if child u5 not attending
  3. child protection referral = in complex / deteriorating situations, follow local guidelines, refer to social services if required

25
confounding variable
a factor other than the one being studied that may distort or mask the effects of another variable on the disease in question e.g. age
26
case control study
retrospective study of people with disease vs people without disease looks back in time at exposure to particular risk factor disadv - recall or selection bias / confounding / time relationships
27
case report
report on single pt or series of pts no control group & no valid statistical associations
28
cohort study
establish group of individuals in population, measure exposures, follow up over period of time, identify those who have the disease disadv controls difficult to identify / confounding / blinding difficult / large sample if disease rare / time consuming
29
rct
strongest evidence on effectiveness of tx
30
p value
used in stats to help determine significance of results if <0.05 you reject the null hypothesis & your results are statistically significant note - want narrow CI as larger the sample, smaller the CI
31
confidence interval
range of values that a true population tx effect is likely to lie estimate of the amount of uncertainty of a sample
32
NNT
number needed to treat no of pts needed to tx to get 1 pt to experience outcome so you want low NNT
33
4 main communication skills for guiding style
OARS open questions affirmations reflective listening summary

36
types of abuse (5)
verbal emotional financial physical sexual
37
how to deal with domestic violence in practice
AVDR ask - in non judgemental way validate - removes blame, believing & taking seriously document - specifically what pt says in notes in own words refer - signpost to where they can seek help
38
why alcohol abuse causes problems in dentistry
decreased synthesis of clotting factors in damaged liver combined with reduced absorption of vit k dependent ones thrombocytopenia due to splenomegaly associated with portal hypertension megakaryocyte maturation decreased leading to fewer platelets platelet aggregation reduced leading to prolonged bleeding reduced drug metabolism for LA / analgesia / sedatives
39
alcohol limit M & F
<14 units / week spread evenly over 3+ days
40
screening tools for alcohol
1. AUDIT - gold standard 2. FAST - most practical 3. PAT - used in A&E

46
general health implications of smoking
- narrows arteries & increased atherosclerosis - increased risk of stroke - increased chest infections / COPD / lung cancer / emphysema / bronchitis / increased stomach ulcers & cancer - increased CHD / heart attacks - macular degeneration & PVD
47
stress
acute pressure leads to specific reactions from nervous / endocrine system hypothalamus responds by increasing cortisol chronic stress leads to longer term high cortisol levels thus effects on BP / immune system / hippocampus / memory / emotions
48
symptoms of stress
physical - exhaustion / GI problems / headaches / SoB / sleeplessness psychological - touchy / irritable / lethargy / anger
49
summary of stress risk factors (6)
control support relationships role change demand
50
burnout
process whereby a previously committed professional disengages from his / her work in response to stress / strain experienced in the job
51
3 scales of burnout

53
4 key ingredients of resilience
1. reaching out 2. rational thinking 3. awareness 4. fitness
54
critical appraisal
process of assessing & interpreting evidence through systematic consideration of its validity, relevance & results use PICO to determine if trial addressed a clearly founded issue
55
CASP tool
critical appraisal skills programme set of questions allowing us to go through paper asking if set results were valid & whether they apply for primary which is 1 paper on 1 study
56
systematic review
type of literature review that uses systematic methods to collect 2ndary data, critically appraise research studies & synthesise studies designed to provide complete summary of current evidence relevant to research question
57
adv of SR
saves time provides reliable evidence resolves inconsistencies explores differences between studies identified when questions have been fully answered identifies gaps
58
how does SR reduce bias
in gathering, summarising, presenting, interpreting & reporting of research evidence
59
key characteristics of SR (5)
1. well formulated q (PICO) 2. comprehensive data search 3. unbiased selection & abstraction process 4. assessment of papers 5. synthesis of data
60
risk of bias assessment for RCT (6)
1. sequence generation 2. blinding 3. selective outcome reporting 4. other i.e. funding 5. incomplete data outcome 6. allocation concealment
61
reporting bias
publication citation time lag language
62
what is blinding
concealment of group allocation from 1 or more of the individuals involved in trial
63
what is meta analysis
process of using statistical methods to combine results of different studies aim is to integrate findings, pool data & identify overall trend of results it is an optional part of SR
64
what does meta analysis do (4)
1. calculates tx effect based on pooled data from group of studies 2. estimates common tx effect across studies 3. improves precision of a point estimate by using all available data 4. increases sample size
65
2 different types of data
1. dichotomous - binary (is or is not) i.e. odds ratio, risk ratio, ARD, NNT 2. continuous - bp / weight / amount of pain
66
vertical line on forest plot
where the tx and control have the same effect i.e. the value of no difference
67
diamond on forest plot
relative risk which is outcome of intervention / outcome of control i.e. % who died with steroid / % who died with placebo
68
horizontal line at bottom of forest plot
the scale measuring tx effect caution - read labels as to the left does not always mean that treatment to the left is better than the control
69
heterogeneity
differences between studies that may produce different results 3 types: - clinical - methodological - statistical
70
to identify heterogeneity visually
if studies estimating the same thing we would expect CIs to overlap to a large extent so may appear in forest plot as poor overlap of CIs therefore, can't draw line through CIs as they don't overlap so wouldn't want to pool these
71
to test for heterogeneity
1. chi squared test = P<0.1 demonstrates statistically significant heterogeneity so may not be appropriate to pool data 2. I squared statistic = % variation due to heterogeneity rather than chance (<50% acceptable)
72
what does cochrane use to evaluate quality of body of evidence
GRADE Grading of Recommendations Assessment Development & Evaluation
73
5 factors that lower the quality of GRADE
1. high / unclear risk of bias 2. inconsistency between studies i.e. heterogeneity 3. indirectness i.e. PICO 4. publication bias 5. imprecision i.e. numbers & CIs
74

76
5 steps of clinical audit
1. identify problem 2. set criteria standards 3. observe practice / data collection 4. compare performance with criteria / standards 5. implement change
77
6 dimensions of health care
timely efficient effective equitable person centred safe
78
consent must be
1. valid -> recently obtained / remain current / specific to proposed tx 2. legal -> ability i.e. capacity / informed / voluntary
79
7 factors influencing SIMD category
employment status crime housing income education geographical access health / health care services
80
what is an addiction
chronic, primary, neurobiological condition influenced by genetic, psychosocial and environmental factors
81
risk factors for drug misuse & addiction
genetic socioeconomic male environmental personality - low self esteem social circles who are also drug users method of drug admin early exposure stress abuse trauma
82
reward pathway
activated by rewarding stimulus i.e. food / water / sex information travels from VTA (ventral tegmental area) to nucleus accumbens and then up to prefrontal cortex dopamine mediated transmission allows us to feel pleasure
83
2 variables on fluoride toxicity
1. weight of child 2. strength of toothpaste
84
management of fluoride overdose
<5mg/kg = calcium orally & observe for a few hrs 5-10mg/kg = calcium orally (milk / calcium gluconate) and admit to hospital >15mg/kg = admit to hospital immediately, cardiac monitoring & like support, IV calcium gluconate
85
what is the position called for seating
balance / neutral position - 90 degree angle at hip & bone - thighs roughly parallel to floor - feet on floor, back & neck upright - shoulders relaxed - move with chair, do not bend / twist / stoop
86
zones for right handed operator
imagine pt head is at 12 o'clock 7-11 = operating zone 11-2 = static zone 2-4 = nurse's zone 4-7 = transfer zone
87
direct aspiration
- adjacent to tooth being treated - aspirator placed slightly distal - do not obscure view of operator - bevel should be adjacent to tooth - remove excess fluid at back of mouth - do not go over tongue to access back of mouth
88
indirect aspiration
- useful if access limited or aspirator obscures view - anterior 3-3 position aspirator on side closest to you - if operator on LHS this would then be on lower right quadrant - if operator on RHS this would then be on lower left quadrant - remove water / debris without obscuring view
89
if dental dam on
3in1 should still be used required for washing & drying teeth keeps mirror clean and clear for indirect vision
90
5 methods of soft tissue retraction
aspirator dental mouth mirror tongue depressor 3in1 cheek retractor
91
for UR quadrant
3in1 retract & supports cheek aspirator on palatal surface distal to tooth
92
for LR quadrant
3in1 retracts & supports cheek aspirator between tongue and lingual surfaces
93
for UL quadrant
3in1 retracts & supports lower lip & cheek aspirator retracts & supports cheek & is placed in buccal sulcus
94
for LL quadrant
3in1 retracts & supports lower lip careful not to press lip onto teeth aspirator retracts & supports cheek
95
anterior region
ensure lips retracted & protected CW rolls mouth mirror support CW rolls with 3in1
