Dental care utilization growth slowed significantly after 1978. Economic factors, dietary changes like reduced sugar intake, and a structural shift in demand explain this trend.

Area of Science:

  • Health Economics
  • Dental Public Health
  • Time-Series Analysis

Background:

  • Per capita real dental expenditures in the U.S. grew annually by 3.33% from 1950-1978.
  • Utilization growth experienced a sharp decline between 1978 and 1989, prompting investigation into contributing factors.

Purpose of the Study:

  • To develop and apply a model for analyzing time-series data on dental care utilization.
  • To quantify the impact of economic and dietary factors on dental care utilization trends.

Main Methods:

  • A combined model of dental care demand (incorporating prices, income, sugar, sweeteners, fluoridation) and supply was developed.
  • A two-stage estimation procedure was applied to U.S. aggregate time-series data from 1950-1989.
  • The model analyzed the relationship between economic variables, dietary factors, and dental care utilization.

Main Results:

  • Economic factors (net price, income) and dietary factors (reduced sugar consumption, increased noncaloric sweeteners) significantly impacted utilization.
  • Decreased sugar consumption was associated with reduced dental care utilization.
  • Fluoridation showed a weak positive relationship with utilization, and a significant structural demand shift occurred post-1978.

Conclusions:

  • Economic, dietary, and structural demand shifts are key contributors to the observed curtailment in dental care utilization growth.
  • The model accurately reflects the flattening of per capita real dental expenditures post-1978.
  • Findings provide insights into the complex interplay of factors influencing dental care utilization.
