๐ฆท Medical conditions and dental health: Systemic diseases, drugs, and deficiencies can all leave characteristic oral signs.
โ ๏ธ Persistent, unexplained oral lesions always warrant further investigation to exclude malignancy or systemic disease.
๐ About
- Many medical conditions impact oral health, producing characteristic oral manifestations.
- Understanding these links helps dentists and doctors work together for holistic patient care.
๐งช Common Medical Categories
- ๐ Systemic conditions (e.g. diabetes, HIV, pregnancy, osteoporosis, cardiovascular disease)
- ๐ก๏ธ Autoimmune disorders (e.g. Sjรถgrenโs, pemphigus)
- ๐งฌ Genetic conditions (e.g. amelogenesis imperfecta, dentinogenesis imperfecta, ectodermal dysplasia)
- ๐ Medications & treatments (e.g. phenytoin, bisphosphonates, fluorosis)
- ๐ Nutritional deficiencies (e.g. scurvy, calcium deficiency)
๐ Systemic Conditions
- Diabetes mellitus: periodontal disease, candidiasis, delayed healing.
- Osteoporosis: alveolar bone loss, โ risk of tooth loss, implant complications.
- HIV/AIDS: candidiasis, hairy leukoplakia, Kaposi sarcoma.
- Pregnancy: pregnancy gingivitis, โ periodontal risk โ adverse pregnancy outcomes.
- Eating disorders: erosion from vomiting (bulimia), enamel hypoplasia (anorexia).
- Cardiovascular disease: drug-induced dry mouth (antihypertensives, ฮฒ-blockers).
๐ก๏ธ Autoimmune Disorders
- Sjรถgrenโs syndrome: severe xerostomia, rampant caries, candidiasis.
- Pemphigus vulgaris: fragile oral bullae, painful erosions, secondary infection risk.
๐งฌ Genetic Conditions
- Amelogenesis imperfecta: enamel defects, discoloured/pitted teeth.
- Dentinogenesis imperfecta: blue-grey or amber teeth, brittle with fractures.
- Ectodermal dysplasia: hypodontia, conical teeth, enamel hypoplasia.
๐ Medications & Treatments
- Fluorosis: enamel mottling, brown discolouration.
- Xerostomia-inducing drugs: antihypertensives, antidepressants, anticholinergics โ โ caries & periodontal risk.
- Bisphosphonates: risk of osteonecrosis of jaw after extractions.
๐ Nutritional Deficiencies
- Vitamin C deficiency (scurvy): bleeding gums, poor wound healing, tooth loss.
- Calcium deficiency: enamel hypoplasia, brittle teeth, alveolar bone weakness.
๐ Classic Oral Signs & Systemic Links
- ๐ต Blue Burtonโs line: lead poisoning.
- ๐ค Yellow/brown teeth: tetracycline use in childhood.
- ๐ฆท Hutchinsonโs incisors: congenital syphilis (notched, peg-shaped).
- ๐ค Brown mottling: fluorosis.
- โซ Blue-black pigmentation: haemolytic anaemia.
- ๐ฃ UV-fluorescent dark teeth: congenital erythropoietic porphyria.
- ๐คข Erosion + halitosis: bulimia nervosa (acid exposure).
๐ฌ Investigations
- ๐ฆท Comprehensive dental exam (caries, enamel defects, periodontal health).
- ๐ท Imaging: OPG/periapical X-rays; bone density scans if osteoporosis/bisphosphonates.
- ๐งช Labs: glucose, B12, folate, iron, calcium, HIV testing where appropriate.
- ๐ฌ Biopsy: suspicious leukoplakia/erythroplakia โ exclude malignancy.
๐ Management
- ๐ฏ Treat the underlying disease: e.g. optimise diabetes, manage HIV, replace deficiencies.
- ๐ฆท Dental care: regular scaling, fluoride, restorations, sealants.
- ๐ Medication adjustments: avoid xerostomia-inducing drugs where possible; saliva substitutes/stimulants.
- โ ๏ธ Special caution: bisphosphonates โ avoid extractions if possible; liaise with max-fax if surgery needed.
๐ Prognosis
- Varies with underlying condition & timeliness of management.
- Early recognition of systemic-dental links prevents serious complications.
- Best outcomes with multidisciplinary care (dentist + GP + specialist).
