38
types of dementia
Alzheimers
Vascular
Frontotemporal
dementia with lewy bodies
39
How is Alzheimers caused?
reduction in size of the Cortex
Plaques (deposits of beta-amyloid protein) build up in spaces between nerve cells
tangles (twisted fibres of tau protein) built up inside cells
40
How is vascular dementia caused?
reduced blood flow to the brain, which damages and eventually kills the brain cells
can develop as a result of
- small vessel disease
- a single large stroke
- lots of mini strokes
41
dementia with Lewy bodies is caused by...
deposits of an abnormal protein called Lewy bodies inside brain cells
- also found in people with Parkinson's
42
dementia risk factors
age
gender
genetic background
medical history
lifestyle
43
give at least 3 features of a dementia friendly healthcare environment
reception desk visible from entrance door
ceilings, floors and floor coverings should be acoustically absorbent to support audible communication
colour and tone of walls should be distinctive from flooring
colour and tone of furniture should be distinctive from flooring
avoid non-essential signs
any signage should be at eye level with simple clear use of text and colour
ensure good levels of natural light
any staff only or locked rooms should be coloured the same as walls to avoid attention
44
risk factors for drug misuse and addiction
men 2x as likely
genetics
socioeconomic factors
environmental:
- home and family, friends and acquaintances that do drugs
personality
- low self esteem
- stress
availability
coexisting mental problems
peer pressure
physical and sexual abuse
early exposure to drugs
45
You have an addiction problem. What should you do?
put interest of your patient first
consult senior colleague to ask for advice and support
- document encounter if you are the colleague
are you safe to practice?
support groups
- British doctors and dentists group
engage with medical services
46
one of your patient's is an alcoholic, what considerations would you make in regards to treating them?
morning appointments
- least likely time to be under the influence
patient may have poly-substance misuse including smoking
sedatives have an addictive effect with alcohol
GA best avoided
- increased risk of vomiting and inhalation of vomit
- may be resistant to GA
many recovering addicts may be on disulfiram (Antabuse)
- psychoitic reaction with metronidazole
47
alcohol abuse potential dental implications
advanced caries, periodontal disease and NCTSL
angular stomatitis
RAS
increased risk of leukoplakia and oral cancer
dialysis
erosion
nocturnal bruxism
dry mouth secondary to dehydration and vomiting
48
considerations to take prior to an extraction on an alcoholic
impaired wound healing
liver cirrhosis = bleeding risk
avoid use of aspirin and NSAIDs
- paracetamol safest analgesic
49
dental implications of opiate abuse
trauma
infective endocarditis
enhances sedation agents
impaired drug metabolism
oral neglect
50
methadone - dental implications
high sugar content
- 5ml methadone = 2.5mg sugar
- sugar free prep available
caries rate higher in methadone users
51
dental advice for methadone users
use a straw
drink water after consumption
- prevents regurgitation
don't brush teeth immediately after
engage with dental services
prevention
sugar free suspension available
52
opioids - dental considerations
suboptimal oral hygiene and self care
use leads to salivary hypofunction
- xerostomia
- caries
- burning mouth
- taste impairment
smooth surface, buccal and cervical caries often present prior to beginning methadone therapy
anxiety and opioid use can reduce effectivenesss of LA
injecting drug users at greater risk of BBV and endocarditis
can cause thrombocytopenia putting patients at risk of post op bleeding
- especially if liver function impaired
53
patient smokes cannabis and is due to come in for sedation appointment. what advice should you give prior to appointment?
patients should be advised to not use cannabis for at least 72 hours before treatment under conscious sedation in order to reduce the likelihood of drug interactions and unpredictable sedation quality
54
cocaine dental and facial consequences
bruxism, clenching and NCTSL
gingival erosions, retraction and ulcerative lesions at the site of application - owing to rubbing of powder topically
- resolve upon abstaining from use within 2weeks to 18 months
chronic sinusitis
nasal crusting
epistaxis (nose bleeds)
higher periodontitis risk
use of powder intramurally = decrease in saliva pH
enhances body's response to adrenaline
links between cocaine use and development of cluster headaches
55
treating cocaine users in practice - considerations
defer dental treatment for 6-24 hours after last administration of cocaine
administration of LA after recent cocaine use can lead to acute increase in blood pressure
- use of lidocaine may increase chance of convulsions
56
long term physical effects of cocaine use
palatal and nasal septum perforation due to acidic nature and vasoconstrictor
57
methamphetamine use dental implications
poor oH
- meth mouth = rampant caries
bruxism, clenching and NCTSL
xerostomia
risk of osteonecrosis of mandible
