British Columbia School Screening Dental Program, A Regional and Provincial

Analysis

Introduction:

In 1990, a standardized public health dental screening program was implemented in

British Columbia. This dental screening program involved public health dental care

professionals who performed dental screening as part of classroom dental health

education sessions. During the screening program, kindergarten children were assessed

for:

evidence of no visible dental decay (caries-immune)

evidence of no visible decay but evidence of existing restorations

evidence of pain or infection at the time of screening

evidence of visible dental decay (caries) in one or more teeth, and

location of decay by quadrant of the mouth.

In March 2005, government announced a commitment to improve early childhood

development. The dental health initiative was one part of an integrated cross-ministry

strategy for addressing dental, hearing, and vision concerns in the early childhood years

(birth to five years of age). Health Authorities received increased funding to enhance

early childhood dental health programs. The goal was to provide programs that would

offer the best opportunity to improve the dental health and well-being of infants and

children. The Early Childhood Dental Health initiative included:

Provision of increased public health dental health services through registered

dental hygienists and certified dental assistants, so that health authorities

could increase prevention of early childhood caries and improve identification

of higher risk, more vulnerable segments of the population

Increased access to dental treatment, especially for low-income families, and

Public awareness and education program related to early childhood caries.

Health authority dental staff have continued to monitor the impact of early intervention

programs on dental health through ongoing dental surveys of kindergarten children. The

kindergarten survey provides a measurement of the success of these services in

improving the dental health of the young children. In 2006-2007, a province wide dental

survey was conducted by health authority public health dental staff to assess the dental

health of kindergarten children.

This report provides a comparative summary to 2001-2002 data and is based on the

British Columbia School Screening Dental Program, A Regional and Provincial Analysis

April 2003 document. Although 1993-2000 screening data is included in some graphs,

this report will only compare screening results collected from 2001 to 2002 with

kindergarten dental survey data collected in 2006 to 2007.

The rationale for limiting comparisons to the 2001-2002 and 2006-07 data is that for this

time period there was greater consistency of screening practices and data recording


practices. It is important to note however, that there are limitations in performing direct

comparisons as the 2006-2007 data was based on a universal survey where as the 2001-

2002 data was more targeted to specific communities and schools.

In 2006-2007 school year, 35,602 children participated in the provincial dental survey

(91% of all those enrolled).1

Important Notes:

For comparative purposes, the area of Okanagan has been kept as North

Okanagan and Okanagan Similkameen.

Cariboo was part of Northern region in the 2003 report. Data from Cariboo is

now included as part of Thompson Cariboo Shuswap region.

Revelstoke was part of North Okanagan region in the 2003 report. Data from

Revelstoke is now included as part of Thompson Cariboo Shuswap region.

Conclusion

The 2006-07 kindergarten dental survey provides a measurement of the success of early

intervention programs in improving the dental health of the young children. The 2006-07

dental survey data showed that while there was an overall improvement in the oral health

of children surveyed, some parts of the province continue to experience worse dental

health. The Core Public Health Functions for BC: Evidence Review. Dental Public

Health, 2006 indicates that the Federal, Provincial and Territorial Dental Directors

suggested a Canadian goal of 60% of children at age 5-6 be caries free103

. Provincial

dental survey results indicate that this target was attained in 2006-07.

In the 2006-07 school year, 82.8% of surveyed kindergarten children in B.C. (91% of

those enrolled) were decay free at the time of the survey. Of these children, 61.1% had no

evidence of having had decay (no decay and no fillings present). 104

Since 2001-02, the percentage of children with no evidence of decay has increased in

three of five health authorities, the percentage of children with no visible decay but

restorations present has decreased in four of five health authorities, and the percentage of

children with visible decay has decreased in three of five health authorities.105

Since 2001-02, the percentage of decay in quadrants 1 and 2 have decreased by 0.5%

while the percentage of decay in 3 and 4 quadrants has increased by 0.2% and 0.4%

respectively. 106

While BC has met the target for children with no visible decay, it remains clear that

children in some parts of the province remain consistently worse off in their dental

health. Children in the Northwest, Richmond, Thompson Cariboo Shuswap, Vancouver

and Kootenay Boundary show higher rates of visible decay than the provincial average.

These same health service delivery areas also show lower rates of no decay but

restorations present than the provincial average. In addition, three of these service areas

(Richmond, Northwest and Thompson Cariboo Shuswap) had the highest rates of decay

in four quadrants.

Health authority dental staff has continued to monitor the impact of early intervention

programs on dental health through ongoing dental surveys of kindergarten children.

Since 2001-02, the percentage of children in BC with visible decay has decreased and the

percentage of children with no visible decay (caries immune) has increased showing an

improvement in oral health.

Program final 106


Program final


The Dental Public Health Program has identified three key components for early

childhood dental health. These are dental health promotion, dental disease prevention and

surveillance. The provincial dental survey is key for monitoring trends between regions

and within communities as well as for evaluating the effectiveness of multiple prevention

strategies in an effort to decrease the rate of dental caries in young children. Subsequent

kindergarten surveys will be important for monitoring trends and identifying changes in

the oral health status of children.
