Aim:
The study aims to determine the Early Childhood Caries (ECC) prevalence in the Olomouc region, Czech Republic, and to evaluate the associated risk factors in a group of children aged up to six years.
Methods:
A cross-sectional epidemiological study on ECC prevalence and risk factors was conducted in the Olomouc region, Czech Republic, from January to December 2024. The cohort involved 104 children aged up to six years who received a dental examination in their kindergartens, following parental written informed consent and a questionnaire completion. ECC prevalence was assessed, and risk factors were identified after data processing and analysis.
Conclusion:
Despite existing preventive measures, ECC prevalence remains high, indicating the need for more targeted prevention addressing the main risk factors, such as consumption of sweet and sour beverages, and lower family income in families. Conversely, oral hygiene from the eruption of the first tooth, positively related to the prevalence of ECC, should be promoted.

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
Assessment of the Mouth
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...
