Dental caries and attendance to dental care in Finnish children with operated congenital heart disease. A practice based follow-up study

Abstract

Purpose

Oral health of children with congenital heart disease (CHD) is of utmost importance. This study aimed to investigate the prevalence of dental caries and attendance to dental care in Finnish heart-operated CHD patients born in 1997–1999.

Methods

The cohort of children born in 1997–1999 was selected using a national register on all heart-operated children in Finland. Gender, general health problems, diagnosis, type of the heart defect (shunting, stenotic and complex defects), and number of operations were available and included in the analyses. Dental records from primary health care were collected from municipalities with their permission. The data comprised of the number of dental examinations and data on caries status (dt, DT, dmft, DMFT) at the age of 7 (grade 1), 11 (grade 5) and 15 (grade 8) years and at the most recent examination. The control group consisted of dental data on patients born in 1997–1999 provided by the City of Oulu, Finland ( n = 3356).

Results

Oral patient records of 215/570 children were obtained. The difference between the defect types was statistically significant both for DT ( p = 0.046) and DMFT ( p = 0.009) at the age of 15 (grade 8). The prevalence of caries did not differ between the study population and the controls. High present and past caries experiences were not associated with higher number of visits to oral health care, especially to oral hygienist, or with oral health promotion. National obligations concerning dental visits were not implemented in all municipalities.

Conclusion

There seems to be a need for oral health promotion and preventive means implemented by oral hygienists among those with CHD.
