Background:
The Ontario Cleft Lip and Palate/Craniofacial Dental Program was established to fund dental care for those with oral clefts, craniofacial anomalies, congenital oral defects, and acquired facial/oral defects.
Aim:
To determine the annual rates of newly registered oral clefts, craniofacial anomalies, congenital oral defects, and acquired oral defects cases on the Program from 2007 to 2018 and identify trends in registration rates during this time period.
Design:
Data were obtained from the Program from 2007 to 2018. Annual, age-specific incidence rates (for age groups 0-4, 5-9, 10-14, 15-19, and 20-24 years) were calculated for new registrations in each diagnostic category, plotted and examined using Poisson regression analysis to identify trends.
Results:
Rates of new registration for oral clefts and acquired oral defects were stable from 2007 to 2018. The rates of newly registered cases of craniofacial anomalies and congenital oral defects showed an increased trend from 2007 to 2018, although year-by-year comparison of the change in rates did not reach statistical significance. For craniofacial anomalies, congenital oral defects, and acquired oral defects, the highest rates of new registrations occurred in the age group 10 to 14 years, while those aged 0 to 4 recorded the highest registration rates in the oral cleft group.
Conclusion:
Rates in new cleft and acquired oral defects registrations were stable from 2007 to 2018. Rates in newly registered cases of craniofacial anomalies and congenital oral defects increased over the 11-year period.
