Study Notes
Definition of Dental Caries
- Dental Caries is a disease characterized by the destruction of the tooth's hard structures.
- Intensity of caries is directly linked to acid production and the presence of acid-producing bacteria.
- Key bacteria involved in dental caries:
- Streptococcus mutans can produce caries alone.
- Co-occurrence with Lactobacillus acidophilus enhances caries development.
Factors Influencing Dental Caries Incidence
- Microorganisms: Acid-producing bacteria increase caries risk.
- Host Factors: Reduced saliva secretion heightens the likelihood of caries.
- Dental Morphology: Well-spaced teeth lower caries incidence, while fissures and pits elevate it.
- Tooth Composition: Elements like fluoride decrease caries risk; Cu and Mn may increase it.
- Dietary Habits: Frequency and duration of carbohydrate consumption contribute to caries incidence.
Stages of Dental Caries Development
- Initial phase involves enamel demineralization.
- Appearance of small white spots indicates early decay.
- Discoloration intensifies over time.
- Surface of the tooth softens, allowing decay to progress into the dentin.
- Spread of caries occurs laterally and deeper into the tooth structure.
- Cavitation appears as decay deepens.
- Lesions advance to affect the pulp, causing sensitivity to stimuli and eventual pulp damage.
- Bacterial infection may reach the root canal, causing abscesses through the apex.
General Factors Affecting Caries Occurrence
- Tooth Composition, Morphology, and Orientation: These traits influence how susceptible teeth are to caries.
- Plaque Biochemistry and Bacteriology: The composition of dental plaque is critical in caries development.
- Food Composition and Dietary Habits: Dietary choices significantly affect the risk of developing caries.
Factors Associated with Caries Resistance
- Increased caries risk is associated with minerals such as copper, magnesium, zinc, vanadium, and lead.
