Frequency, cost, and time to re-treatment after active periodontal therapy.
Article in Journal of periodontology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundSupportive periodontal therapy (SPT) reduces the probability of infection reoccurrence further disease progression. Despite that, several patient/tooth related variables have been linked to tooth loss during SPT. This longitudinal study examines the correlation between periodontal staging, grading, initial therapy, and frequency, cost, and time-to-re-treatment following active periodontal therapy (APT).
methodsPatients who received scaling and root planing (SRP) or surgery (SUR) were included. Demographics, annual SPT visits, and medical history were collected. Radiographic bone loss (RBL), probing depths (PD), and clinical attachment loss were collected at six sites/tooth. A simple binary logistic regression model assessed the probability of re-treatment. Multiple models were constructed while adjusting for confounding factors: sex, age, number of SPT visits, and baseline data.
resultsThree hundred patients underwent SRP, and 142 underwent SUR as their APT. 191 patients (63.7%) required a second intervention over 24 ± 8.2-year follow-up. The second intervention type was correlated with the first (p = 0.035). The likelihood of a second intervention was higher in SUR patients (p < 0.001). Significant differences in time to first intervention based on stage (p = 0.019) and compliance (p < 0.001). Similar patterns were observed for time-to-recurrence based on stage (p = 0.03) and compliance (p = 0.017) but not grade (p = 0.144). Mean teeth "free of intervention time" was 16.3 years before the first additional therapy. However, SSD was found between stages (p = 0.028) and grades (p = 0.043) for SUR interventions, but not for SRP.
conclusionIn this long-term study, higher stage patients and those who had surgical treatments received more frequent retreatments. The first intervention affected the likelihood and type of the second intervention. 12.4% of patients were responsible for 64% of the entire retreatment spending. PLAIN LANGUAGE SUMMARY: Patients with more severe periodontitis who initially underwent surgery needed more frequent therapy. Patients who had surgery as their intervention during active periodontal therapy were more prone to have surgery as their additional therapy during follow-up.
