Study Notes
Dental Calculus
- Dental calculus is mineralized bacterial biofilm
- It forms 48 hours to 2 weeks after plaque biofilm formation
- It's composed of 10-30% organic material and 70-90% inorganic material
- Inorganic components include magnesium phosphate, calcium carbonate, and calcium phosphate
- Organic components include plaque bacteria, dead epithelial cells, and white blood cells
- Crystals of dental calculus include calcium brushite, octocalcium phosphate, calcium hydroxyapatite, and magnesium whitlockite
- Crystalline content varies based on factors like location (anterior or posterior teeth, supra or subgingival), age of calculus, and individual differences
- Calculus can attach to teeth through acquired pellicle, penetration into enamel, cementum, or dentin, or by adhering to tooth irregularities
Learning Outcomes
- Students should be able to define dental calculus
- Classify calculus based on location
- Describe calculus structure and the processes involved in its formation
- Understand the differences between supra and sub calculus
- Describe the varying appearances of calculus and how it adheres to teeth
- Explain the role of calculus in dental disease progression
- Describe the relevance of dental calculus to dental practice
Calculus Location and Attachment
- Calculus can form on the gingival crevice, root surfaces with periodontal pockets, and prostheses
- Calculus adheres to restoration ledges, imbricated teeth, and occlusal surfaces
- Calculus location relates to the gingivae
Relevance of Calculus
- Calculus formation rate varies among individuals and across different teeth
- Individuals can be classified based on calculus formation rate as heavy, moderate, slight, or non-calculus formers
- Calculus can be detected visually and radiographically
Detection Methods
- Visual inspection of teeth is a common method of detection
- Radiographs can also be used to detect calculus
- Other methods of detection are required
Impact on Clinicians and Patients
- Clinicians must understand the impact of calculus on patients
- Considerations must include the impact on treatment choices and the likelihood of recurrence
