Occurrence rate and estimated economic burden of pulp and periapical disease treatment among Korean older adults: a national population-based retrospective study.
Article in Epidemiology and health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesMaintaining healthy dentition is essential for the overall health of older adults. Treatment of pulp and periapical disease (PPD) is crucial for preserving teeth. This study assessed the occurrence rate and economic burden of PPD treatment in an older Korean population.
methodsData were obtained for adults aged ≥65 years from the Korean National Health Insurance Services from 2014 to 2018. The occurrence rate was defined as the proportion of individuals who received ≥1 PPD treatment. The economic burden was estimated using both direct and indirect expenditures, calculated from a societal perspective. Regression analysis was performed to evaluate yearly trends in occurrence rate and economic burden.
resultsDirect costs, which included insured and non-insured medical expenses, ranged from US$13.79 million to US$10.47 million. Indirect costs, comprising transportation and time costs, ranged from US$0.89 million to US$0.80 million. Total costs declined from US$14.68 million to US$11.36 million. The occurrence rate of PPD treatment decreased significantly from 1.24% to 0.91% (p<0.05). The economic burden also demonstrated a statistically significant downward trend, with total PPD costs decreasing from 0.00099% to 0.00066% of Korea's GDP, and from 0.63% to 0.30% of the annual total dental care benefit costs between 2014 and 2018 (p<0.05).
conclusionsThe occurrence rate and estimated economic burden of PPD treatment significantly decreased among older Korean adults from 2014 to 2018. Conservative approaches to tooth preservation contribute to more effective oral health policies and help reduce the economic burden of oral disease treatments in an aging society.
