Insights
Early childhood caries (ECC) affects over half of young children in Manitoba, with similar prevalence across urban and First Nations communities. This study highlights ECC as a significant issue requiring further prevention efforts.
Area of Science:
- Pediatric Dentistry
- Public Health
- Epidemiology
Background:
- Early childhood caries (ECC) is a severe form of tooth decay affecting young children.
- Limited prevalence data exists for ECC in Manitoba, despite indications of high treatment demand.
- Long waiting lists for hospital treatment of ECC suggest a significant problem in the province.
Purpose of the Study:
- To determine the prevalence of ECC in children under 6 years old in four Manitoba communities.
- To assess the oral health status of these young children.
- To identify potential risk factors associated with ECC.
Main Methods:
- Four communities in Manitoba were selected based on the number of young children needing dental treatment under general anesthesia.
- Two communities were in the southern region, and two were in the northern region.
- Each region included a disadvantaged urban community and a First Nations (on-reserve) community. Caregivers completed interviews and children received dental examinations.
Main Results:
- A total of 408 children participated. The overall prevalence of ECC was 53.7%, with no significant difference between urban and First Nations communities.
- The mean number of decayed, extracted, or filled teeth was 4.2.
- Older children and those with more plaque were more likely to have ECC; caregiver education level was not associated with prevalence.
Conclusions:
- ECC represents a serious public health concern in Manitoba.
- This study provides essential baseline data for evaluating current and future ECC prevention strategies in the studied communities.
Objectives:
Early childhood caries (ECC) is a particularly destructive form of tooth decay that afflicts young children. Although few prevalence data have been published for Manitoba, long waiting lists for treatment of ECC in hospital indicate that many children in the province suffer from this condition. The purpose of this investigation was to determine the prevalence of ECC and the oral health status of children under 6 years of age in 4 communities in Manitoba and to identify risk factors associated with ECC.
Methods:
The 4 Manitoba communities were selected according to the best available data regarding the number of young children scheduled for dental treatment under general anesthesia. Two of the communities were located in the southern region of the province, and the other 2 were northern communities. In each region, one community represented a disadvantaged population in a large urban centre, whereas the other was a First Nations (on-reserve) community. The parent or guardian (primary caregiver) of each child under 6 years of age was invited to participate. After informed consent had been obtained from the caregiver, each child underwent a dental examination of the deciduous dentition, and the caregiver completed a retrospective questionnaire by interview.
Results:
A total of 408 children and their caregivers participated in the study. The overall prevalence of ECC was 53.7%, and the prevalence was similar in all 4 communities, with no statistically significant difference in caries between the high-risk urban communities and the First Nations (on-reserve) communities. The mean number of decayed, extracted or filled teeth +/- standard deviation was 4.2 +/- 5.0. Older children were more likely to have ECC (p < 0.001), but the caregiver"s level of education was not associated with ECC prevalence (p > 0.05). Children with ECC also exhibited more plaque (p < 0.001).
Conclusions:
The results of this study indicate that ECC is a serious problem in Manitoba. In addition, this investigation establishes a baseline to help evaluate the effectiveness of current and future prevention initiatives in these 4 communities.

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.
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...
