Dental Caries Experience in Elementary School Students in Quebec: Surveillance Study Using ICDAS II
Journal (Canadian Dental Association)
|December 16, 2020
Summary
Dental caries is a significant public health issue affecting Quebec youth. This study highlights the need for enhanced preventive strategies to improve children's oral health and reduce tooth decay prevalence.
Area of Science:
- Public Health
- Pediatric Dentistry
- Epidemiology
Background:
- Dental caries remains a prevalent issue among children in Quebec.
- Assessing the oral health status of elementary school students is crucial for public health surveillance.
- Previous studies may not have utilized comprehensive caries assessment criteria.
Purpose of the Study:
- To evaluate the oral health status of Grade 2 and Grade 6 students in Quebec.
- To determine the prevalence and indicators of dental caries in primary and permanent dentitions.
- To inform public health strategies for caries prevention in children.
Main Methods:
- A cross-sectional study involving 2875 Grade 2 and 2788 Grade 6 students across Quebec.
- Oral health examinations conducted by 16 calibrated dentists using the International Caries Detection and Assessment System (ICDAS) II criteria.
- A stratified sampling design ensured provincial representativeness.
Main Results:
- Mean decayed, missing, filled teeth (dmft) and surfaces (dmfs) indexes were calculated for both age groups.
- Grade 2 students showed higher combined dmft+DMFT (5.84) and dmfs+DMFS (11.28) than Grade 6 students (5.98 and 9.96, respectively).
- A high percentage of students (90-92%) exhibited signs of caries (dmfs + DMFS > 0).
Conclusions:
- Tooth decay continues to be a significant public health concern for Quebec's youth.
- The findings underscore the necessity of strengthening preventive dental care programs.
- Utilizing ICDAS II for population-level surveillance and combining primary/permanent dentition data offers valuable insights.

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
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...
