Long-term periodontal maintenance in a patient with Papillon-Lefèvre syndrome: an 8-year case report.
Article in BMC oral health, 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
backgroundPapillon-Lefèvre syndrome (PLS) is an autosomal recessive disorder with a prevalence of approximately 1-4 cases per one million individuals. This condition frequently leads to premature loss of both the primary and the permanent teeth. PLS is primarily caused by mutations in the cathepsin C (CTSC) gene, resulting in the loss of CTSC function, which disrupts immune regulation and triggers severe inflammatory responses. Maintaining and preserving teeth in these patients therefore presents a significant challenge for periodontists. CASE PRESENTATION: The patient received multidisciplinary treatment involving periodontics, oral and maxillofacial surgery, and prosthodontics. Hopeless teeth were extracted, removable dentures were provided, and supportive periodontal maintenance was performed over an 8-year period. Adjunctive systemic antibiotics were used during active treatment and selected maintenance visits because of severe inflammation and multiple sites with suppuration, but this approach was not designed as a standardized long-term antibiotic protocol.
resultsAt the latest follow-up, 22 natural teeth were retained. The bleeding on probing rate decreased from 71% at baseline to 18% in March 2025, the proportion of sites with probing depth ≥ 4 mm decreased from 54 to 27%, and the Plaque Index improved from 2-3 to 1-2. Clinical attachment level was not consistently recorded and therefore could not be analyzed longitudinally.
conclusionThis single case suggests that early diagnosis, extraction of hopeless teeth, individualized multidisciplinary periodontal-prosthodontic management, regular supportive periodontal care, sustained plaque control, and strong family cooperation may help prolong the retention of functional natural teeth in selected patients with Papillon-Lefèvre syndrome. Further longitudinal studies with standardized periodontal, microbiological, and antimicrobial-resistance monitoring are needed.
