Study Notes

Dental Caries

Dental caries (decay) is a dynamic process of demineralization and remineralization.
Decay is initiated by acids produced when bacteria in the mouth digest carbohydrates on the tooth surface.
These acids demineralize the tooth surface, leading to the destruction of dental tissues.
Initially, the process is reversible, but it can become irreversible.

GDC Learning Outcomes

Describe oral diseases and their relevance to prevention, diagnosis, and treatment.
Explain the aetiology and pathogenesis of oral disease.
Assess and manage caries, occlusion, and tooth wear. Restore the dentition using minimal intervention to maintain function and aesthetics.

Intended Learning Outcomes

Explain the worldwide healthcare issues associated with dental caries.
Describe dental caries based on its causative factors.
Describe dental caries based on its anatomical location.
Describe dental caries based on its stage of progression.
Explain how basic management principles may vary for different clinical presentations of dental caries.

Aetiology of Dental Caries

Caries formation involves susceptible tooth surfaces, plaque, bacteria, and fermentable carbohydrates.
Time, fermentable carbohydrates, plaque, and bacteria are all involved in the process.

Histopathology of Enamel and Dentine Caries

Information about the microscopic structure of enamel and dentine in carious lesions.

Types of Dental Caries

Arrested/Inactive: Demineralization and remineralization are balanced. The lesion may have healed, leaving a scar.
- Reasons for arrest: improved oral hygiene or removal of a plaque retention cause.
- Characteristics: White or slightly discoloured area, smooth and hard texture on probing
- Treatment: Fluoride application, composite or glass ionomer cement (if discolouration is a concern).
Root Caries: Affects cementum and dentine, primarily occurs when roots are exposed due to recession. Progression is faster due to the softer cementum. This results from decreased salivary flow, xerostomia, and frequent consumption of sugar. -Treatment: Preventative measures (oral hygiene instruction, fluoride use, diet advice). Treatment (restorations with glass ionomer cement (fluoride releasing) or composite resin). -Treatment considerations: isolation is challenging (ideal use of rubber dam); if adequate enamel is present, use of composite; if enamel is absent, use of GIC materials
Early Childhood Caries: Presence of one or more decayed, missing, or filled primary teeth in preschool-aged children (0–71 months). Often related to prolonged exposure to sugary liquids from bottles/nursing.
Rampant Caries: Extensive decay affecting several teeth, due to rapid progression or immune characteristics in certain teeth.
- Treatment needs vary; some need extensive preventive measures, others need stabilisation with temporary restorations to assess response to interventions.
Caries Based on Anatomical Position: Caries are classified by location:
- Class I: Pit and fissure caries on occlusal surfaces of premolars and molars.
- Class II: Proximal caries on premolars and molars.
- Class III: Proximal caries on incisors and canines, not involving the incisal edge.
- Class IV: Proximal caries on incisors and canines, involving the incisal edge.
- Class V: Gingival caries on the facial and lingual surfaces of all teeth.
- Class VI: Incisal or cusp tip caries on anterior or posterior teeth without affecting another surface..
Primary/Secondary: Primary caries targets untreated surfaces. Secondary caries targets previously treated surfaces (e.g., a filling).
Residual Caries: Remaining caries after restoration. This can be accidental or intentional (e.g., close to pulp, sealing with fissure sealant).
White Spot Lesions/Incipient Caries: The initial evidence of carious activity. These lesions may reverse with proper preventative procedures, exhibiting as white spots.
