In vivo assessment of the Optipen optical reflectometer for detecting enamel surface changes following an erosive challenge.
Trial report in Clinical oral investigations, 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
objectivesTo evaluate whether the Optipen optical reflectometer can detect enamel surface changes associated with erosion under clinical conditions. MATERIALS AND
methodsIn this short-term parallel randomized clinical trial, 24 healthy participants were allocated to two groups: Test (T-rinse with a cola beverage for 30 s) and Control (C-rinse with water). Surface reflectance was measured using the Optipen optical reflectometer on the maxillary central incisors at baseline, immediately after rinsing, and after 2 h of salivary exposure, and expressed as the percentage of surface reflection intensity.
resultsThe test group showed significantly lower reflectance values immediately after the erosive challenge (65.4) compared with the control group (102) (p < 0.05). After 2 h of salivary exposure, no significant differences were observed between groups (T = 85.7 and C = 97.8).
conclusionsThe Optipen optical reflectometer detected immediate changes in enamel surface reflectance in vivo following a single erosive challenge. CLINICAL RELEVANCE: This device may be useful for detecting immediate enamel surface changes following erosion. Further studies are needed to optimize reflectance measurements after salivary exposure.
