The effects of retinoic acid therapy on salivary and serum IL-1β, IL-8 and MCP-1 levels in periodontally healthy individuals: a prospective cohort study.
Observational study in Clinical oral investigations, 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
objectivesThis prospective cohort study analyzed the effects of systemic retinoic acid use on periodontal status, salivary flow rate (SFR), and salivary and serum levels of interleukin (IL)-1β, IL-8, and monocyte chemoattractant protein (MCP)-1. MATERIALS AND
methodsTwenty-four periodontally healthy participants (13 females, 11 males; aged 18-30 years) were enrolled. Serum and saliva sampling, SFR recordings, and periodontal examination were performed at four different time intervals: before (T0), at the 6th week (T1), at the 5th month (T2), and after the completion (T3) of retinoic acid treatment. Saliva and serum cytokine levels were measured with Luminex assay. Friedman test compared cytokine levels and periodontal parameters between visits. P-values of < 0.05 was considered statistically significant.
resultsGingivitis was observed in 33.3% of participants and remained after treatment in 16.7%. Serum IL-8 and MCP-1 levels (p < 0.05) and SFR (p < 0.001) decreased during treatment. Serum MCP-1 reached to its lowest level after treatment (p < 0.05). No significant changes were observed in salivary cytokines or serum IL-1β levels.
conclusionSystemic retinoic acid use is related to increased gingival inflammation, decreased salivary flow, and suppressed systemic chemokine response. These findings suggest that retinoic acid may create a specific risk for individuals prone to develop periodontal diseases. CLINICAL RELEVANCE: This research clarifies the potential oral health implications of retinoic acid therapy, which is widely used. This may enable the establishment of specific oral and gingival care protocols tailored for this group of patients. Consequently, timely and evidence-based interventions could help maintain long-term oral health in these patients.
