Methods - Analysis
descriptive analysis SPSS 20.0 & SAS 9.3
regression analysis
Immigrant/refugee - Independent t-test & Mann-
Whitney U Tests, (continuous variables)
Chi Square test & Fisher's Exact Tests (categorical
variables), as applicable for categorical variables
outcome of interest for logistic regression was
presence/absence of at least one carious tooth
9. www.usask.ca
Results
Refugee children had statistically significant higher DMFT
scores than immigrant children (p<0.001)
a) Refugee mean dmft/DMFT score 5.80±4.24
b) Immigrant mean dmft/DMFT score 3.52±3.78
c) Significant difference only in f/F between populations
d) mean score of 0.48 ±1.52 (immigrant) and 1.55±2.36
(refugees) p<0.001
Significantly higher than dmft/DMFT scores for Canadian
children

Results
Significant differences between adult immigrants vs.
refugees & adult immigrants had:
a) significantly higher proficiency in English language
b) More knowledge about oral health
• Brushing after meals (p<0.009)
• Causes of tooth decay (p<0.002)
• Benefits of fluoride (p<0.001)
• Knowledge of plaque (p<0.003) components like fluoride and
dental floss compared to refugee adults.

Summary
Refugee children > immigrant children re: disease
Immigrants/refugee children > oral disease experience
& treatment needs than Canadians
in line with other at-risk population groups
Other priorities take precedent over dental care & lack
of financial resources becomes barrier when seeking
care
Language is key barrier (p<0.0001)
Need to link immigrants/refugees with resources
