Study Notes
Etiology of Dental Caries
- Main factors involved in dental caries etiology: host qualities of enamel, microorganisms, fermentable carbohydrates, and time. Saliva also plays a role.
- Enamel resistance depends on tooth morphology, age, fluoride intake, and internal/external factors, and nutrition during dental histogenesis.
- Main etiological factors for caries: enamel as the host, disease-causing microorganisms, production of acids (fermentable carbohydrates), time, and saliva.
Resistance of Enamel Structures
- Factors contributing to high enamel resistance: tooth age, morphology, fluoride intake, nutrition during histogenesis, and local/systemic factors.
Critical Period of Tooth Mineralization
- The particularly critical period for tooth mineralization after eruption is the first 2 years.
Molar Morphology
- Molar morphology is characterized by pits, grooves, and fissures. These are areas of retention for microorganisms and food, with the fissure bottom having the lowest mineralization.
Permanent Teeth After Eruption
- Permanent teeth immediately following eruption have a lower degree of mineralization, smoother surfaces, larger crystals, smaller intercrystalline spaces, and narrower interprismatic zones.
Cariogenic Microorganisms
- Key qualities of cariogenic microorganisms: ability to adhere to tooth surfaces, survive in the oral environment, and multiply in sufficient numbers.
- Aciduric microorganisms actively reproduce in acidic environments.
- Important microorganisms for caries development are Streptococcus mutans, Streptococcus mitis, Streptococcus sobrinus, Streptococcus oralis, and Lactobacillus.
Stephan's Curve and Caries
- Factors in Stephan's curve linked to caries incidence and sugar intake include physical form of sugar, frequency of sugar intake, and quantity of sugar intake.
Bacteria and Caries Development
- Streptococcus mutans is highly cariogenic due to its affinity for enamel pellicle colonization, carbohydrate metabolism into acids, ability to live in acidic conditions, and links with sucrose.
