Dental Anxiety Before Non-Surgical Periodontal Treatment: Evaluating the Interaction of Gender and Education Level.
Article in Oral health & preventive dentistry, 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
purposeDental anxiety is a multidimensional factor that influences treatment compliance and periodontal outcomes. This investigation evaluated how gender, educational level, and their combined interaction relate to dental anxiety in a sample of patients receiving initial non-surgical periodontal therapy (Phase I), minimizing potential confounding effects from procedural differences. MATERIALS AND
methodsThis cross-sectional study included 200 volunteers (100 females, 100 males) who received Phase I periodontal therapy. The required sample size was estimated using G*Power analysis to achieve a statistical power of 95%. Dental anxiety was assessed using the Modified Dental Anxiety Scale (MDAS). Age homogeneity between genders was confirmed using the independent samples t-test. Data were analyzed using two-way ANOVA, the Games-Howell post-hoc test, and simple effects analysis. Effect sizes were determined via partial eta squared (partial η²).
resultsNo statistically significant difference in mean age was found between genders (p = 0.890). Two-way ANOVA revealed no statistically significant main effect for gender (p = 0.683) or educational level (p = 0.315). However, a statistically significant interaction effect with a large effect size was observed between gender and educational level (F(3,192) = 13.237; p 0.001; partial η2= 0.171). Simple effects analysis demonstrated that anxiety levels statistically significantly decreased as educational level increased in females (partial η² = 0.197), whereas in males, anxiety levels paradoxically increased with higher education (partial η² = 0.175).
conclusionThe impact of education on dental anxiety is not uniform but is statistically significantly modulated by gender. These findings emphasize the necessity of moving beyond standardized communication toward a customized, gender- and education-tailored chairside approach to optimize compliance during non-surgical periodontal therapy.
