Impact of imaging protocol and tube current adjustment on the radiation dose in CBCT imaging of mandibular incisors.
Article in Clinical oral investigations, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectivesThis study aimed to assess the impact of imaging protocols involving tube current (mA) adjustment on the equivalent and effective radiation dose for cone-beam computed tomography (CBCT) of mandibular incisors using the corresponding periapical radiography as clinical reference.
methodsAn anthropomorphic head and neck phantom equipped with 24 thermoluminescent dosimeters (TLDs) was used to evaluate radiation exposure across seven imaging protocols: high-dose CBCT (4.0, 7.1, and 10 mA), low-dose CBCT (3.2, 4.5, and 6.3 mA), and standard periapical radiography (7 mA). Equivalent and effective radiation doses were calculated according to tissue-weighting factors outlined in ICRP Publication 103.
resultsEffective dose increased proportionally with tube current, ranging from 53 to 175 µSv in high-dose protocols and from 8.6 to 18 µSv in low-dose protocols. Periapical radiography yielded the lowest effective dose (1.4 µSv). The highest equivalent doses were recorded for the salivary glands and oral mucosa across all protocols.
conclusionsCBCT protocols with reduced tube current significantly decrease radiation exposure. The lowest setting tested (3.2 mA) resulted in an effective dose comparable to six periapical radiographs. These findings support the implementation of low-dose CBCT for complex endodontic diagnostics, particularly during initial evaluations, in alignment with the ALADAIP principle.
