Effect of a phthalocyanine mouthrinse after connective tissue graft surgery for root coverage: a randomized split-mouth clinical trial.
Trial report in Oral and maxillofacial surgery, 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 effects of self-activating phthalocyanine mouthrinse on recipient sites of subepithelial connective tissue graft (SCTG), considering clinical outcomes, professional and patient assessments and quantitative somatosensory changes. MATERIALS AND
methodsThis randomized controlled, crossover, split-mouth clinical trial included 20 patients treated with SCTG plus coronally advanced flap (CAF). Recipient sites received 0.12% iron phthalocyanine mouthrinse (test group-PHY) and 0.12% chlorhexidine (control group-CHX) during 14 postoperative days. The primary outcome was percentage of root coverage (%RC) at 6 months. Secondary outcomes included clinical parameters (probing depth, PD; recession depth and width, RD, RW; percentage of complete root coverage (CRC); clinical attachment level, CAL; keratinized tissue thickness and width, KTT, KTW), professional- and patient-reported outcomes, mechanical detection threshold (MDT) and mechanical pain threshold (MPT).
resultsPHY and CHX groups showed significant improvements in clinical parameters, including reduced RD and RW, CAL gain, and increased KTW and KTT (p < 0.05). %RC was similar between groups, at approximately 80%. Professional- and patient-reported outcomes, including dentin hypersensitivity and esthetic perception, as well as MPT and MDT, showed no significant differences between groups. Postoperative symptoms decreased progressively, and oral health-related quality of life remained unchanged after 6 months.
conclusionsPostoperative use of phthalocyanine after CAF + SCTG resulted in clinical outcomes comparable to chlorhexidine, including similar root coverage, with no differences in professional-, patient-centered outcomes, somatosensory profile, or oral health-related quality of life. CLINICAL RELEVANCE: Iron phthalocyanine may represent a promising alternative for postoperative care in periodontal plastic surgeries.
