Analysis of implementation status and influencing factors of standard infection control methods for dental environmental surfaces by dental hygienists in South Korea: a questionnaire-based study.
Article in BMC oral health, 2026. 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
backgroundGiven reports that the Coronavirus Disease 2019 can survive on environmental surfaces for a period, public attention to surface disinfection has increased. However, only a few studies have investigated the current status of standard infection control practices for environmental surfaces. Therefore, we aimed to investigate the implementation status of standard infection control methods for dental environmental surfaces among South Korean dental hygienists and to analyze the factors influencing these practices.
methodsA survey was conducted to investigate surface infection control methods in dental office environments. A questionnaire, consisting of general characteristics and infection control methods stratified by environmental surfaces, was distributed to dental hygienists. Overall, 190 dental hygienists responded to the survey; responses from eight participants with incomplete data were excluded, and the remaining 182 responses were analyzed using SPSS software.
resultsThe surfaces with the highest implementation rate of standard infection control methods were the bracket Table (23.1%), followed by the light-curing unit head. In contrast, drawer handles (0.5%) had the lowest implementation rates. The odds of implementing standard infection control methods were higher for dental hygienists treating 40 or more patients daily compared with those treating 19 or fewer patients. In addition, the odds of implementing standard infection control methods were higher when an infection control personnel was present than when absent.
conclusionBased on a thorough understanding of dental institutions and accumulated evidence, our findings highlight the need to improve standard infection control methods for efficient implementation, and offer strategies to increase their implementation.
