    Study Notes

    Definition and Prevalence

    • Dental caries, also known as tooth decay or cavities, is a bacterial infection that causes demineralization of tooth enamel, leading to destruction of the tooth structure.
    • It is one of the most common chronic diseases affecting people of all ages, with an estimated 60-90% of school-age children and nearly 100% of adults worldwide experiencing dental caries.

    Causes and Risk Factors

    • Bacterial fermentation of sugars and starches: The primary cause of dental caries is the fermentation of sugars and starches by bacteria, particularly Streptococcus mutans and Lactobacillus acidophilus.
    • Poor oral hygiene: Inadequate brushing and flossing allow bacteria to accumulate on tooth surfaces.
    • Inadequate saliva flow: Saliva helps to neutralize acid and remineralize teeth.
    • Diet: Frequent consumption of sugary and acidic foods and drinks.
    • Genetics: Some individuals may be more prone to dental caries due to genetic factors.

    Stages of Caries Development

      1. Initial caries: Bacteria penetrate the tooth enamel, causing demineralization.
      1. Enamel caries: The bacteria continue to demineralize the enamel, creating a visible lesion.
      1. Dentin caries: The bacteria penetrate the dentin, causing a more extensive lesion.
      1. Pulpal involvement: The bacteria reach the pulp, leading to inflammation and potentially abscesses.

    Signs and Symptoms

    • Toothache or sensitivity to heat, cold, or sweet stimuli
    • Visible cavities or discoloration on the tooth surface
    • Pain when biting or chewing

    Prevention and Management

    • Good oral hygiene practices: Brushing with fluoride toothpaste, flossing, and regular dental check-ups.
    • Dietary modifications: Limiting sugary and acidic foods and drinks, and promoting a balanced diet.
    • Fluoride supplements: Applying fluoride varnishes or using fluoride mouthwash to strengthen tooth enamel.
    • Restorative treatments: Filling cavities, crowns, and root canals to restore damaged teeth.

    Complications

    • Tooth loss: If left untreated, dental caries can lead to tooth loss and affect overall oral health.
    • Systemic infections: Bacteria can spread from the mouth to other parts of the body, causing systemic infections.
    • Malnutrition: Difficulty eating and digesting food due to tooth loss or pain can lead to malnutrition.

    Definition and Prevalence

    • Dental caries, also known as tooth decay or cavities, is a bacterial infection that causes demineralization of tooth enamel, leading to destruction of the tooth structure.
    • It is a chronic disease affecting people of all ages, with 60-90% of school-age children and nearly 100% of adults worldwide experiencing dental caries.

    Causes and Risk Factors

    • Bacterial fermentation of sugars and starches is the primary cause of dental caries.
    • Streptococcus mutans and Lactobacillus acidophilus are the primary bacteria responsible for caries.
    • Poor oral hygiene, including inadequate brushing and flossing, allows bacteria to accumulate on tooth surfaces.
    • Inadequate saliva flow hinders the neutralization of acid and remineralization of teeth.
    • Frequent consumption of sugary and acidic foods and drinks contributes to dental caries.
    • Genetic factors can increase an individual's susceptibility to dental caries.

    Stages of Caries Development

    • Initial caries involves bacterial penetration of the tooth enamel, causing demineralization.
    • Enamel caries is characterized by the continued demineralization of the enamel, creating a visible lesion.
    • Dentin caries involves the penetration of bacteria into the dentin, causing a more extensive lesion.
    • Pulpal involvement occurs when bacteria reach the pulp, leading to inflammation and potentially abscesses.

    Signs and Symptoms

    • Toothache or sensitivity to heat, cold, or sweet stimuli are common symptoms of dental caries.
    • Visible cavities or discoloration on the tooth surface are signs of dental caries.
    • Pain when biting or chewing is also a symptom of dental caries.

    Prevention and Management

    • Good oral hygiene practices, including brushing with fluoride toothpaste and flossing, can prevent dental caries.
    • Regular dental check-ups are essential for preventing and managing dental caries.
    • Dietary modifications, such as limiting sugary and acidic foods and drinks, can help prevent dental caries.
    • Fluoride supplements, such as fluoride varnishes or mouthwash, can strengthen tooth enamel.
    • Restorative treatments, including filling cavities, crowns, and root canals, can restore damaged teeth.

    Complications

    • Untreated dental caries can lead to tooth loss and affect overall oral health.
    • Bacteria can spread from the mouth to other parts of the body, causing systemic infections.
    • Difficulty eating and digesting food due to tooth loss or pain can lead to malnutrition.
