A questionnaire study on dental radiation knowledge and anxiety among patients applying to a faculty of dentistry.

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
backgroundThe aim of this study was to evaluate patients' knowledge-related responses, attitudes, anxiety levels, and radiation risk perceptions regarding dental radiographic imaging methods. MATERIALS AND
methodsA structured 30-item questionnaire was administered face-to-face to 410 participants. Anxiety and radiation risk perception were assessed using a 5-point Likert scale, while knowledge-related responses were evaluated using categorical responses. Constructs were analyzed separately as anxiety (emotional response to radiographic procedures), risk perception (radiation-related concerns), and knowledge-related responses (factual awareness of radiation).
resultsA total of 410 participants were included (mean age: 32.98 ± 12.66 years; 58.8% female). Overall anxiety levels regarding radiographic procedures were low; however, increased anxiety was observed in situations involving radiation exposure and absence of protective aprons. Radiation risk perception was generally at a moderate level; however, the tendency to refuse or postpone radiographic examinations recommended by the dentist was low. Female participants had higher radiation risk perception scores; however, this difference was not statistically significant. Regarding knowledge-related responses, participants demonstrated higher awareness of computed tomography (CT) and natural background radiation, while uncertainty was prominent regarding magnetic resonance imaging (MRI) and panoramic radiography (PR) dose.
conclusionAlthough patients generally tolerate dental radiographic procedures with low anxiety, uncertainties regarding radiation exposure contribute to increased perceived risk. These findings highlight the need for structured, evidence-based patient information strategies to improve radiation literacy and support informed acceptance of dental imaging procedures.
