Clinical efficacy and safety of photodynamic therapy combined with tea polyphenols in treating peri-implantitis.
Article in American journal of translational research, 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
objectiveTo evaluate the clinical efficacy and safety of photodynamic therapy (PDT) plus tea polyphenols (TP) in treating peri-implantitis.
methodsThe clinical records of 91 peri-implantitis patients treated at the North China University of Science and Technology Affiliated Hospital and Tangshan Hongci Hospital were analyzed retrospectively. Forty-one patients who received PDT alone were assigned to the control group, while the other 50 patients receiving both PDT and TP were allocated to the study group. Periodontal indices, inflammatory factors, swallowing function, pain, MOS 36-Item Short-Form Health Survey (SF-36) scores, therapeutic effect and adverse reactions were compared between the two groups.
resultsPost therapy, significant reductions in the modified plaque index (mPLI), modified sulcus bleeding index (mSBI), probing depth (PD), and clinical attachment level (CAL) were observed in both groups (P<0.05), with more notable decreases in the study group (P<0.05). Besides, the levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) as well as interleukin-1β (IL-1β) also decreased notably in both groups (P<0.05), with notably lower levels in the study group (P<0.05). SF-36 scores across all dimensions significantly improved in both groups (P<0.05), with the study group demonstrating more substantial improvements (P<0.05). Swallowing function scores significantly decreased in both groups (P<0.05), with a more marked improvement in the study group (P<0.05). Similarly, the VAS scores of both groups significantly decreased post-treatment (P<0.05), especially the study group (P<0.05). In contrast to the control group, a notably higher overall response rate was observed in the study group (P=0.020), while no significant inter-group difference was observed in the total incidence of adverse reactions (P=0.683).
conclusionPDT plus TP is more effective than PDT alone in treating peri-implantitis. This combined approach significantly reduces inflammation, improves periodontal health, and enhances quality of life, without increasing the incidence of adverse reactions. These findings suggest its potential for broader clinical application.
