Disclaimer
The data visualizations presented in this dashboard are created using the Canadian Health Measures Survey Public Use Microdata File (CHMS-PUMF) from Cycle 1. In alignment with PUMF use policy, the users of this dashboard are reminded of the following:
Purpose: The results presented here are aimed to be used for exploring the PUMF data. We recommend the users of follow the guidelines from Statistics Canada regarding the publication of analysis from PUMF.
Warning: The Confidence Intervals(CI) and Coefficient of Variance(CV) of the estimates may not be reliable as the bootstrap weights were not provided with the Public Use Microdata File for confidentiality purposes.
Limitations: It is important to recognize the limitations of Public Use Microdata File. To protect the privacy of participants, Statistics Canada has modified the PUMF with some noise. Hence the results presented in the dashboard can be different from what could be obtained from the CHMS Master file. Users of the dashboard are reminded to refer to the documentation from Statistics Canada for proper use cases for results from PUMF.
By accessing this dashboard, users acknowledge and agree to abide by the terms outlined above.

Descriptive table for the DMFT plot
Interpretation of coefficient of variance are as follows:
A - Estimates are acceptable and considered for unrestricted release
E- Estimates can be generally released without restrictions, but should include a warning to users about the high sampling variability of these estimates.
F- Estimates are of unacceptable quality

DMFT Index Definition
The Decayed, Missing and Filled Teeth(DMFT) index is a numeric value that represents the decayed, missing, and filled teeth in an individual's mouth. It is commonly used to assess oral health and dental caries risk. The index is calculated based on the number of decayed (D), missing (M), and filled (F) teeth.
Formula: DMFT = D + M + F
Where:
Formula: DMFT = D + M + F
Where:
- D: Number of decayed teeth
- M: Number of missing teeth
- F: Number of filled teeth
-
Interpretation:
- The index relies on the principle that dental hard tissues do not regenerate, and once caries develop, they leave a permanent mark. Consequently, the DMFT index is irreversible and serves as a measure of lifelong caries experience.
- The DMFT index score ranges from 0 to 32, with a higher score indicating a greater extent of caries experience.

OHI-Simplified Index Definition
The Oral Hygiene Index - Simplified (OHI-S) is a measure of oral hygiene that assesses the presence of debris and calculus in the oral cavity. It is used to evaluate the effectiveness of oral hygiene practices. The index is calculated based on the debris index (DI) and the calculus index (CI).
Formula: OHI-Simplified = DI + CI
Where:
Formula: OHI-Simplified = DI + CI
Where:
- DI: Debris Index
- Formula for Debris Index (DI): DI = (Number of tooth surfaces with debris) / (Total number of tooth surfaces)
- CI: Calculus Index
- Formula for Calculus Index (CI): CI = (Number of tooth surfaces with calculus) / (Total number of tooth surfaces)
-
Interpretation:
- OHI-S <= 1: Good oral hygiene
- 1 < OHI-S <= 2: Fair oral hygiene
- OHI-S > 2: Poor oral hygiene

COH Dashboard User Manual
Welcome to the Canadian Oral Health (COH) Dashboard! This user manual will guide you through the operation of the dashboard, enabling you to efficiently explore and analyze community oral health data.1. Select Outcome Variable: Begin by specifying the outcome variable you wish to analyze by selecting the tabs on the top of the dashbord. This variable represents the oral health outcomes that you want to investigate within the selected dataset. Currently, there are two outcome variables- DMFT Index and OHI-S. However, more variables will be added through future updates
2. Choose Filters: Next, select one or more filters from the provided options in the Filter Selection Panel. These filters may include demographic variables (e.g., age group, gender). Click on the checkboxes to make your selections. The variable of interest filter (drop-down menu) on the top left corner defines the x-axis of the graph. This filter enables the you to see the distribution of desired oral health component based on your variable of interest. However, before changing this filter, it is good practice to reset the pre-selected filters to avoid clutering of the graph
3. Explore Results: Once you have selected filters and specified the outcome variable, the dashboard will dynamically update to display the relevant results through error plots. Explore the displayed statistics and confidence intervals(error-bars) to gain insights into the dataset.
4. Interact with Visualizations: If data visualizations are available, interact with them to further explore the dataset visually. Hover over data points, zoom in/out, or toggle between different visualization types to uncover patterns or trends in the data.
5. Refine Analysis: To refine your analysis, adjust the selected filters or choose a different outcome variable as needed. The dashboard will update in real-time to reflect your changes, allowing you to iteratively explore different aspects of the dataset.
6. Download or Export Data: Depending on the dashboard features, you may have the option to download or export the analyzed data, visualizations, or summary statistics for further analysis or reporting purposes.
Note: The estimates derived from this dashboard do not reflect the exact estimates derived from the CHMS master file. To know more about the CHMS-PUMF please click the link: CHMS-PUMF
