Role of systemic factors (periodontal disease) Flashcards
What is the Primary aetiological factor causing periodontal disease?
Plaque
What does gingivitis result from?
Accumulation of plaque over a number of days
What appearance do gums have if they have gingivitis?
- Swollen papilla
- Reddened gingiva
- Gross plaque deposits around the gingiva
- Gums bleeds on probing
- More roles gingival margins
What does periodontitis arise from?
Plaque accumulation and an appropriate host response
What are the 2 categories that the secondary aetiological factors fall under?
Local factors
Systemic factors
Name the 6 systemic aetiological factors
- Environmental
- Metabolic
- Genetic/ inherited
- Behavioural
- Life style
- Haematological
What factors fall under environmental aetiology?
Dug therapies
What factors fall under metabolic aetiology?
Sex hormones
Diabetes
What can gingival over growth (hyperplasia) be caused by in some patients?
Drugs and hormones
Describe what happens in gingival overgrowth
There is no loss of attachment or alveolar bone loss
This condition only affects gingival tissues and is not permanent
Name some groups of drugs that cause gingival overgrowth
- Phenytoins
- Ciclosporin
- Calcium channel blockers
Give examples of Phenytoins
Epanutin
Dilatin
Antiepileptics
Give examples of Ciclosporin
Immunosuppressants
Give examples of Calcium channel blockers
Nifedipine
Verapamil
Amlodipine
Diltiazem
Who is given Ciclosporin?
Renal and heart transplant patients as it is an immunosuppressesant
Who is given Phenytoins?
Epileptic patients
Who is given Calcium channel blockers ?
Renal transplant patients
How can having gingival overgrowth Lead to periodontal disease?
It is harder to obtain good plaque control and so bacteria accumulates on the gingival margins leading to periodontal disease
When are sex hormones given?
During mensuration and pregnancy
Can also be given in the form of a contraceptive pill
What can patients taking oral contraceptives have higher chance of getting?
Hyperplastic, oedematous Gingivitis
What is the degree of inflammation due to in some patients suffering from Hyperplastic, oedematous Gingivitis ?
It is plaque related and related to hormone levels
What type of gingivitis is pregnancy gingivitis?
Plaque induced gingival hyperplasia
When does pregnancy gingivitis usually occur?
After 2 months and it is most severe at 8 months
Is pregnancy gingivitis permanent?
No it usually resolves pithing weeks after giving birth
What else can some pregnant women get?
Pregnancy epulis which is a more severe type of pregnancy gingivitis
What is an epulis?
A swelling in the interdental papilla
What problems arise due to pregnancy epulis?
The red swollen tissue will bleed on touching a brushing making it hard for mothers to brush their teeth and maintain good oral hygiene
How do we manage pregnancy epulis?
By keeping the area as clean as possible until the baby is born
Then the tissue should regress and we can surgically remove the epulis
What percentage of the uK population is affected by diabetes?
2%
Name the 2 types of diabetes
- Type I (insulting dependant)
2. Type II (Non-insulin dependen)
What are both types of diabetes characterised by?
Hyperglycaemia
How can diabetes be managed?
- Diet
- Drugs
- Insulin injections
What do diabetic patients have an increased susceptibility to?
Periodontal disease ie attachment loss and alveolar bone loss
What is the degree of periodontitis severity in diabetic patients related to?
Their level of glucose control
More controlled = less severe periodontitis
Why are diabetic patients at a greater risk of developing periodontal diseases?
As they have an impaired immune response
They are likely to have:
1. a deceased neutrophil function
2. altered chemotaxis and phagocytosis activity
3. Increased inflammatory response
4. Increased coagulation
How can periodontal disease effect diabetic patients?
It can effect their diabetic control
So controlling the periodontal disease can help with controlling glucose levels
What factors fall under genetic aetiology?
Genetic diseases like: Down syndrome Papillon-lefevre syndrome Hypophophatasia Ehlers-danlos syndrome
What do patients with Down syndrome have an increased chance of getting?
Severe periodontal disease like necrotising ulcerative gingivitis
Especially on the lower incisors
Why are down syndrome patients more susceptible to periodontal disease?
They have a defected neutrophil chemotaxis
Have a tendency for mouth breathing
Potentially have poorer oral hygiene
What is papillon lefevre syndrome categorised by?
Palmar plantar keratosis
What is Palmar plantar keratosis
An increased layer of keratin on the palms of the hands and soles of the feeth
What are people with papillon lefevre syndrome more susceptible to?
Rapid periodontal destruction
Why are patients suffering from papillon lefevre syndrome more susceptible to periodontal disease?
As they have a defect of neutrophil chemotaxis and phagocytosis
What is hypophosphatasia characterised by?
Low levels of the enzyme alkaline phosphatase which leads to defective mineralisation and formation of cementum
Rickets like skeletal disease
How are the teeth affected by hypophosphatasia?
As cementum doesn’t form the PDL doesn’t have cementum to insert into so the teeth exfoliate
What is Ehlers-danlos syndrome characterised by?
A disorder of collagen formation Hyperextensibel skin Easily bruised Loose jointedness Dislocation
What is one of the types of Ehlers-danlos syndrome associated with?
Only type VIII is associated with Severe periodontal destruction
pulp stones
Floppy heart sounds
Which type of Ehlers-danlos syndrome is associated with severe periodontal disease?
Type VIII
Type VIII of Ehlers-danlos syndrome is associated with what?
Severe periodontal disease
What is a consequence of Ehlers-danlos syndrome patients having “loose jointedness”
Means they easily loose their teeth and by the age of 30 most of them have lost all their teeth
Dislocation of the TMJ
What factors fall under behavioural aetiology?
Smoking
What is tobacco associated with?
Periodontal disease
What does the severity of periodontal disease depend on in relation to smoking?
The duration of the habit and the number of cigarettes smoked per day
Describe characteristics of periodontal disease in smokers
- Fibrotic gingival with rolled margins
- Deeper pockets around the anterior teeth and palatal sides
- Recession anteriorly
- More alveolar bone loss
- More calculus
- More friction defects
- Reduced gingival blessing
Why is it harder to detect periodontal disease in smokers?
As the gingivae is not red and inflamed and looks fairly normal
Smokers also have reduces gingival bleeding
Why does smoking increase your chances of getting periodontal disease?
- Effects the composition of bacterial flora
- Increased cytokine release
- Increased destruction of extracellular matrix proteins
What are patients who smoke more likely to have?
Destructive periodontal disease
Therapy is less effective in smokers
What should we recommend to patients what smoke?
To quit smoking
We should give them smoking cessation advice
What factors fall under life style aetiology?
Stress
Malnutrition
Why does stress impact your oral health?
- It modulates the neuroendocrine system
- It depresses the immune system
- Produces indirect behavioural effects which can lead to decreased oral hygiene
Name some connective tissue defects
Vitamin C deficiency (Scurvy)
Protein deficiency
What can Vitamin C deficiency (Scurvy) lead to?
Haemorrhagic gingivitis
What can Protein deficiency lead to?
Contributes to loss of periodontal supporting tissues
What factors fall under haematological aetiology?
- Chediak-Higashi syndrome
- Neutropenia
- Leukaemia
What is Chediak-Higashi syndrome characterised by?
Defects of phagocyte chemotaxis, degranulation and membrane fusion
What is Chediak-Higashi syndrome associated with?
- Severe gingivitis
Periodontal destruction resembling 2. Localised Aggressive Periodontitis - Eventual loss of adult dentition
What are the 2 types of neutropenia?
- Cyclic neutropenia

What is Cyclic neutropenia characterised by?
Period of normal neutrophil functions followed by periods when neutrophil function is very low
What is Cyclic neutropenia associated with?
Gingivitis with hyperaemic zone
Gingival ulceration
Rapid periodontal breakdown
What is Familial benign neutropenia associated with?
Gingival oedema or desquamation
But it is often self limiting
What are the 2 broad types of Leukaemia
Acute Leukaemias
Chronic Leukaemias
Acute Leukaemia is seen more in which type of people?
Younger people under their 20s especially in young children
What is Acute Leukaemia associated with?
Gingival swelling
Excessive blessing
Gingival ulcerations
Why are patients with Acute Leukaemia more likely to have periodontal disease?
As they have a lack of healthy white cells to counter the plaque
Why are patients with Acute Leukaemia more likely to swollen gums?
Gingiva swell as they are packed with Acute Leukaemic cells
Chronic Leukaemia is seen more in which type of people?
Older age groups
What is less common in Chronic Leukaemia?
Gingival swelling is less common
