Objectives
–To highlight the medical conditions that can directly affect the provision of dental care and/or consequences of dental treatment. –To address the conditions under:
cardiovascular disorders, disorders of the blood, respiratory disorders, metabolic and endocrine disorders, neurologic disorders, liver disease, renal disease
4
Introduction• There are many medical
conditions that can directly affect the provision of dental care and some where the consequences of dental disease, or even dental treatment, can be life threatening.
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
5
• The definition of a “medically compromised” patient is not precise and in this context, it is interpreted as the presence of a medical factor which may have implications for the provision of dental care.
6
• To achieve optimal oral health for the medically compromised patient, the dentist and physician must work closely.
7
• Because many of these medical conditions are so complex, additional treatment time may be needed to provide these services.
8
• Each patient presents a unique set of challenges to the dentist, but achieving a successful outcome can be a rewarding experience.

11
• Types–Congenital•Heart murmurs , ventricular septal
defects, atrial septal defects, pulmonary stenosis, patent ductus arteriosus, tetralogy of Fallot,
–Acquired •Rheumatic fever, diseases of the
myocardium and pericardium, secondary hypertension
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
12
- Dental management of cardiovascular disorders- Prevent dental disease- OHI, diet
counselling, fluoride therapy, fissure sealants–Any active dental disease must be
treated before cardiac surgery
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
13
–Treatment planning for cardiovascular patients-•Antibiotic prophylaxis given before invasive operative procedures• Ideally short appointments in children for maximal cooperation•Check patient’s platelet count and prothrombin time before tooth extraction
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
14
•No child with symptomatic cardiac problems should have any routine dental procedures until details of the condition have been obtained and the patient’s physician consulted.
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
15
• Endodontic treatment only for teeth with high probability of success like:–Permanent incisors–Straight canals–Closed apices–Single visit
–Consider potential drug interactions and remember some of these patients will be on anticoagulants.
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
16
Blood disorders– Bleeding disorders• Hemophilia• Von Willebrand’s disease• Thrombocytopenia
– Blood dyscrasias• RBC disorders–Anemia -Iron deficiency anemia, Glucose 6-
Phosphate dehydrogenase deficiency, Sickle cell anemia,Thalassemia
• WBC disorders– leukemia
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
17
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
18
• Dental management of bleeding disorders–Communicate with hematologist–Find out the diagnosis/aetiology–NSAIDS alter platelet function and
should not be used.
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
19
–Acceptable analgesics•For acute pain – Acetaminophen, Propoxyphene hydrochloride•For severe pain – Narcotics – heroin, morphine, hydrocodone
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
20
–Care taken while placing intraoral xrays–Local anaesthesia infiltrations or
intraligamentous injections unlikely to cause problems if given carefully–Regional anaesthesia (mandibular
block) contraindicated as bleeding in pterygomandibular region may cause asphyxia
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
21
–Pulp therapy preferred to extractions–Dental extractions or surgery best
managed in hospital setting (use resorbable sutures if needed)–Antifibrinolytics – (e-aminocaproic
acid, tranexamic acid) Used as extra to the factor concentrate replacement to prevent or control oral bleeding
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
22
• High speed vacuum and saliva ejectors used with caution so that sublingual hematomas don’t occur
• Periphery wax used on impression tray• Orthodontic treatment possible- be careful wires don’t
lacerate mucosa• Platelet transfusions are short-lived and if used
prophylactically must be given immediately prior to or during surgery.

Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
26
27
• Dental management of leukemia–Prevent dental caries as these children at high

–Oral surveillance–Topical fluoride therapy, toothbrushing
information–Chlorhexidine mouthwash 0.12%–Nystatin 500,000units ‘swish and swallow–Diet control–Relieve mucositis- Difflam mouthwash,
Quadragel, ice chips Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
28
–Unless dental emergency, no operative dental treatment carried out until child in remission
29
• Once the leukemia is in remission, and after consulting child’s physician, routine dental care can be undertaken with following protocol:
1. Hematological information required to assess bleeding risks
2. Prophylactic antibiotics incase of depressed neutrophil count
3. Fungal infections treated with amphotericin B, nystatin, or fluconazole and herpetic infections with topical and/or systemic acyclovir
4. Regional block anaesthesia contraindicated

Respiratory disorders- Clinical conditions –Asthma–Cystic fibrosis
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
31
• Dental management of asthma–Dental treatment can cause emotional
stress -> attack–Child may take puff of their inhaler
before starting dental treatment–Use analgesics and sedatives with
caution; opioids and sedatives decrease respiratory drive.
32
–Recently a study has been published linking dental erosion with asthma•Could be due to gastro-oesophageal reflux in asthmatics•Or acidic long term medication•Or to increased consumption of erosive beverages due to ‘drying’ of oral mucosa by inhalers
•Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005•Dental erosion in asthma: a case-control study from south east Queensland, Sivasithamparam K et al, Aust Dent J, 2002, Dec;47(4):298-303
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
33
34
• Dental management of cystic fibrosis–These children suffer from delayed dental
development, more commonly have enamel opacities and are more prone to calculus–They need to have higher caloric intake
and may have frequent refined carbohydrate snacks – important priority group for dental health education and care
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005

35
–May also have cirrhosis of liver -> clotting defects -> haemorrhaging following surgical procedures–May be prescribed tetracycline to
prevent chest infections -> intrinsic dental staining–General anaesthesia should be
avoided

Endocrine and metabolic disorders
• Diabetes mellitus• Adrenal insufficiency• Other – thyroid disease, renal
disorders

37
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
38
• Dental management of diabetes–Preventive care–Uncontrolled ->• Increased glucose concentrations in saliva, decreased salivary flow -> dental caries•Periodontal problems and susceptibility to infections (Candida sp)
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
39
–Dental appointments arranged at times when blood sugar levels well controlled; morning immediately after their insulin injection and a normal breakfast
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
40
• General anaesthetics a problem due to the pre-anaesthetic fasting, so normally carried out on an in-patient basis to enable insulin and carbohydrate to be stabilized intravenously
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
41
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
42
• Dental management of adrenal insufficiency–In children, the risks of taking
corticosteroids are greater than in adults and should only be used when specifically indicated, in minimal dosage and for the shortest time possible.
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
43
–if child has adrenal insufficiency or on steroids, any infection or stress may lead to adrenal crisis–For routine restorative treatment
no additional steroids are necessary, but if extractions or other surgeries planned and/or the patient is very apprehensive, then the oral steroid dosage should be increased.
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
44
–General anaesthesia should be carried out on an in patient basis–Consult child’s physician before
prescribing steroids–Anaesthesists must be aware of
such meds in order to avoid fall in blood pressure during anaesthesia or in the immediate post op period.
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
45
• Dental management of thyroid disease–Patient should present no
problems if the as long as they are medically well controlled, however contact with the physician is important
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
46
Neurologic disorder• Febrile convulsions• Epilepsy: most common neurogenic
disorder faced by dentist
47
• Dental management of epilepsy–Sugar free liquid anti-epileptic
medication–The possibility of an attack
occurring in dental chair should be considered

Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
48
–Phenytoin -> gingival enlargement in about ½ of patients–A very high standard of oral hygiene
required to minimize the development of gingival enlargement–Gingival surgery should never be
contemplated unless oral hygiene is good
Paediatric Dentistry, 3rd Edition, by Richard Welbury and Monty Duggal, 2005
49
–Trauma to anterior teeth usually encountered–Reimplantation of avulsed teeth usually
contraindicated in those with severe learning difficulties–If prostheses are required then they
should be well retained with clasps and unlikely to break or be inhaled during attacks

57
–Be cautious with prescribing drugs–Never subject these patients to out-
patient general anaesthesia–Remember veins are precious–Poor bone density -> frequent
denture adjustments–Try to perform dental treatment just
after dialysis if possible
58
Conclusion• Medical conditions have an effect on not only
general health but also oral health. As dental practitioners it is our sole duty to know the medical conditions and how to provide dental care to patients who are suffering from these medical conditions.
• Oral care is important in enhancing quality of life, emphasis being put on preventive care.
