Q

What is the denfition of obesity?

A

Overweight and obesity are defined as abnormal or excessive fat accumulation that may impair health.
A bariatric person is an individual of any age (child to adult) who has limitations in health and social care due to physical size, health, mobility and environmental access.

Q

What defines an obese person?

A

The World Health Organisation defines overweight as a BMI≥25kg/m2 and obesity as a BMI≥30kg/m2.
BMI is defined as weight in kilograms divided by the square of the height in meters.
BMI provides the most useful population-level measure as it is inexpensive, easy to use, the same for both sexes and for all ages of adults.

What are the limitations of BMI?

A

Limitations of BMI:
Does not assess body fat distribution, because it is a measure of excess weight rather than excess body fat.

Q

What is the fundamental cause of obesity?

A

The fundamental cause of obesity and overweight is an energy imbalance between calories consumed and calories expended.

Obesity is a complex, multifactorial chronic disease that is strongly associated with multiple comorbidities.

It is not uncommon to find undernutrition and obesity co-existing.

Multiple factors influence including genetics, socioeconomic status, environment and individual decisions play a significant role.

Q

What “reasonable adjustments” can be made to a dental practice to aid universal access of obese individuals?

A

Reasonable adjustments can be physical, such as alterations to buildings in the form of wheelchair ramps or tactile signage. Or they may mean changes to attitude, such as through policies, procedures and staff training, to ensure that services are as accessible for all patients.
Be aware of comorbidities or predisposition to dental disease.

Appropriate referral onto Secondary and Tertiary care.

May have to provide emergency care prior to onward referral.

Raise concerns with patient, parents or carers of vulnerable adults and children.

Q

What is alcoholic fatty liver disease?

A

Non-alcoholic fatty liver disease (NAFLD) is the term for a range of conditions caused by a build-up of fat in the liver. It’s usually seen in people who are overweight or obese. A healthy liver should contain little or no fat.

Q

What do you need to consider before an appointment for a bariatric patient?

A

Prior to the appointment:
Ensure your venue has appropriate facilities for patient care.
This may involve telephoning the patient/referrer/carer prior to initial visit querying: Patient Weight or BMI, Mobility e.g. do they use a wheelchair? Manual or motorised?

Travel:
Is the patient taking private transport e.g car / taxi? Parking should be available as close to the venue as possible.
Ambulance transport - will only take patients to Hospitals.

Q

What do you need to consider for an obese patient when arriving at the practice and during an appointment.

A

Accessibility:
Waiting room with suitable high weight bearing armless chair.
Adequate door widths
Toilet facilities accessible
Is the practice accessible via lift or stairs

Emergency Evacuation procedures

Under no circumstances should staff attempt to break the fall of an obese patient

Timing:
May require longer appointment times due to reduced mobility
Extra weight around the face can obstruct the access to the mouth
Safety:
Specialist equipment may mean patients need referral tospecialist clinics or hospitals
Wider cuff blood pressure monitors.(e.g. “thigh cuff”); Longer IM needles are needed.
May be unable to get patient rapidly into supine/recovery position or physically move patient.
Airway management may be more difficult.
Resuscitation – identification of landmarks for chest compressions may be difficult

In the chair:
If the patient does not know their weight and is perceived to exceed 22 stone/140kg an accurate weight must be obtained through weighing the patient.
Unfortunately most standard weighing scales only weigh up to 22 stone.
People who carry weight on their chest and upper body are at risk of hypoxaemia when lying flat.
In extreme circumstances some obese patients may present with obesity hypoventilation syndrome, a result of chronic hypoventilation due to the excess weight preventing full expansion of the lungs.

Q

What might an obese patient be difficult to treat?

A

Loss of anatomical landmarks is possible. There are access problems with large cheeks, tongue etc.

ID blocks may be difficult. Alternative techniques may need to be considered such as the Gow-Gates or intraligamentary techniques.

Consider use of a ‘Lax’ tongue retractor if a dental mirror is insufficient for soft tissue retraction

May have to be treated semi-supine or sitting upright – practitioners need to be careful with their posture.

Beware operator musculo-skeletal problems when working in a less than ideal position

Intra-oral radiography can be more challenging due to increased soft tissues.
OPT can be difficult or even impossible if the machine is unable to accommodate the patient’s size.
Long procedures can lead to acute leg oedema, cellulitis, Compartment Syndrome and pressure sores.
Coagulation abnormalities may occur (e.g. due to non-alcoholic fatty liver disease)
Excessive fat in the tissues may also affect pharmacological absorption of a drug

17
Q

What is compartment syndrome?

A

Compartment syndrome: - painful, bleeding and swelling within enclosed muscles increasing pressure, restricts the blood flow and damages nerves/muscles.

18
Q

What is the relationship between obesity and periodontal disease?

A

The relationship between obesity and periodontal disease has been acknowledged as associative but there is no evidence of a causal relationship.
Obesity does not appear to play a negative role in the treatment outcome of non-surgical periodontal therapy.
Diabetic patients have a high associated risk of periodontal disease.
Be aware of the complexity of obesity and be able to discussthe importance of maintaining healthy body weight and performing good oral hygiene procedures.

Caries:
Bariatric patients may have a higher caries rate than general population as causations are interrelated (diet high in processed sugars).

Wound Healing:
Extractions, Surgical Periodontal Treatment, Biopsies;
Bariatric patients are more likely to have reduced immune function leading to delayed wound healing.

Tooth-wear:
Erosive tooth wear is more likely - increased prevalence of GORD in bariatric persons.
Increased incidence of oesophageal reflux, in particular in those having gastric banding, causing acid erosion.

19
Q

How do you treat an obese patient?

A

Full dental and medical histories
Dental examination in patients own wheelchair
Special Investigations: radiograph of painful tooth - finds unrestorable subgingival caries and periapical pathology relating to lower right first permanent molar
Treatment:
Do nothing
Extraction - Positioning of yourself and patient, do you feel confident in your IDB placement, should you take bloods for a coagulation screening? Review healing after?
Extirpation – Positioning of yourself and patient. Can you comfortably place rubber dam?
Referral onto Public Dental Service for bariatric chair for extraction .

20
Q

What are categories of patients receiving domiciliary care?

A

-Neurological and mental illness
-Intelectual impairment due to conditions such as cerebral palsy and epilepsy
-Homeless people in hostels
-Severe CVD
-Hospital in patients
Bariatric patients
-Palliative care patients.

21
Q

What is domiciliary care?

A

Domiciliary care is provided to people who still live in their own homes but require additional support with activities, including household tasks, personal care and any other activity that allows them to maintain both their independence and quality of life.

A domiciliary visit may also be useful for initial assessment, then arranging further review in the clinic. Full risk assessment (as per any domiciliary visit) is essential.
Obese individuals are twice as likely to be cared for in nursing homes
Treatment is usually restricted to inexpensive, short procedures which carry little risk such as examinations.
The most common type of dental procedure carried out is prosthetics.

22
Q

What can you do in emergency appointments for bariatric paients?

A

Provide emergency relief of pain treatment only, weighing up risks and benefits.
Patient and staff health and safety should not be compromised.
If a patient is unsuitable for your dental chair consider treating in their own wheelchair or in a bariatric wheelchair.
Future appointments should be arranged in clinic with suitable facilities.

23
Q

Why are patients with learning disabilities twice as likely to be obese?

A

Those with learning disabilities can experience weight gain, especially those living independently unless they have careful diet control
Thought to be multifactorial, with people with learning disabilities often having poorly balanced diets, more sedentary lifestyles and possible genetic predisposition to weight gain, such is the case in Prader-Willi syndrome or in Down syndrome.
Anti-psychotic medications, such as clozapine and olanzapine, predispose patients to weight gain.

24
Q

How can anxious obese patients treated with sedation?

A

Inhalation Sedation:
No specific contraindications however special care must be taken to ensure good safe airway management.
This may be the most appropriate form of sedation for these patients.
Intravenous Sedation:
Obese adults are at risk of sleep apnoea - a contraindication to dental sedation in a primary care setting.
Bariatric adults are not suitable for conscious sedation in a standard dental clinic due to difficulty placing cannula.
Bariatric adults may have compromised airways which require specialist teams to manage in an emergency with the appropriate resuscitation equipment.
General Anaesthetic:
Obese patients are twice as likely to develop serious airway problems during a GA than the non-obese.

25
Q

What OH advice can GDP provide for a patient after bariatric surgery?

A

GDPs can provide simple and clear messages to patients:
Ingestion of a healthy, balanced diet (reduction in thequantity and frequency of foods and beverages with added sugar, avoid eating at night);
Adequate oral hygiene.
Stimulate salivary flow to avoid dry mouth (increase water ingestion by taking a bottle with you and drinking small sips) +/- artificial saliva;
Increase the consumption of foods rich in fibre;
Chew gum without sugar, but only two month after surgery;
To avoid halitosis or coated tongue, brush the tongue or use a tongue scraper;
Take care to avoid tooth wear (diminish consumption of acidic foods, such as citrus fruit, vinegar and soft drinks);
Drink soft drinks or fruit juices through a straw to minimize contact with the teeth; in case of ingesting soft drinks, never brush right afterwards, but perform mouth rinsing with water;
Never brush the teeth after episodes of vomiting or reflux, if you are not at home, perform mouth rinsing with water or chew gum without sugar; if you are at home: perform mouth rinsing with sodium bicarbonate (one teaspoon in half a glass of water, to alkalinize the oral medium, and wait for half an hour before brushing your teeth).
Provide topical fluoride varnish and OHI as required.
