Abstract

Objectives

The aim of this 7-year study was to examine regional differences in scaling experience rate.

Methods

This study used data on scaling experience rate from the Community Health Survey (CHS) obtained between 2008 and 2014. The standardized frequency of scaling experience rate was analyzed using the SPSS 20.0 program, and shown as a Box Plot. Using the Map Wizard for Excel 10.0, the scaling experience rate in each region was illustrated using Geographic Information System (GIS).

Results

The scaling experience rate in 2008 was 18.6% and in 2014, was 34.9%. From 2008 to 2014, the annual rate of scaling experience increased approximately 1.8 times. The scaling experience appeared to form clustering on GIS, and there were differences in scaling experience rate between cities, towns, and districts. Although the scaling experience rate increased, the gap between regions seems consistent.

Conclusions

The Scaling Experience rate increased annually, but regional differences did not decrease. Therefore, oral health care professionals in each community should strive to improve the scaling experience rate.

Keywords: Community health survey, Regional difference, Scaling experience rate
