Correlates of dental anxiety and phobia in a sample of patients receiving dental care in a dental school setting.
Article in Research square, 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
Background: Dental anxiety, fear, and phobia are common factors that prevent individuals from seeking dental care by delaying dental care or avoiding the visit entirely, which may cause a decline in oral health-related quality of life. Dental anxiety often has a correlation with other psychological constructs. Our aim was to examine the associations between psychological constructs, dental anxiety, and phobia, and its variations among key demographics among patients seeking dental care in a dental school setting. Methods: Baseline data from 499 patients who participated in a randomized clinical trial that evaluated the efficacy of an online intervention in managing dental anxiety was used. Subjects completed a semi-structured interview according to the Diagnostic Schedule Manual-IV (DSM-IV) criteria and self-reported measures on dental anxiety (Modified Dental Anxiety Scale), fear or avoidance of dental care (Clinical Severity Rating), sensitivity to pain (Pain Sensitivity Index), ability to tolerate distress (Distress tolerance scale), blood-injection-injury (Fear Questionnaire For Blood Injection Injury), phobia, and other psychological factors. Paired sample t-tests, ANOVA, and Multivariable Regression Models were used for analyses using R 4.3.2. Statistical significance was set at p-value < 0.05. Results: Mean age of subjects was 48.9±14.7 years old, most were female (71.6%), non-Hispanic (88.6%) with an income lower than $30,000 (40.0%) and most had completed a high school diploma /GED (26%). The majority (63.3%) reported high dental anxiety (MDAS≥19) and 64.57 % met criteria for specific phobia (CSR≥4), with mean scores of 19.53 ± 3.62 and 4.49 ± 1.69 respectively. Mean scores for FQBII, PSI, DTS, and ASI were 15.51 ± 10.15, 68.02±22.9, 44.73±13.2, and 31.0 ± 16.87 respectively. Significant differences in CSR were observed by age (p< 0.01), sex (p= 0.02), and race (p<0.01), while the psychological constructs FQBII, DTS and PSI varied significantly across age, race, and ethnicity (p<0.05). Conclusion: Dental anxiety scores were higher among participants who were African American, low-income, and women compared to Caucasians. Age, sex, income, and race demonstrated to have a strong association with dental anxiety. Subjects with high pain sensitivity and fear of blood/injections had an increased dental anxiety score.
