Periodontal health status in patients treated with the Invisalign(®) system and fixed orthodontic appliances: A 3 months clinical and microbiological evaluation.
Article in European journal of dentistry. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04139538 (Changes of Oral Microbiome and Immunogenity of Saliva During Orthodontic Therapy With Aligners and Multibracket Therapy - a Pilot Study), which is not on this map. Cited by 76 papers, 7 of them syntheses that pooled it.
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.

Abstract
objectiveThe aim of this prospective study was to compare the periodontal health and the microbiological changes via real-time polymerase chain reaction (PCR) in patients treated with fixed orthodontic appliances and Invisalign(®) system (Align Technology, Santa Clara, California). MATERIALS AND
methodsSeventy-seven patients were enrolled in this study and divided into three groups (Invisalign(®) group, fixed orthodontic appliances group and control group). Plaque index, probing depth, bleeding on probing were assessed. Total biofilm mass and periodontal pathogens were analyzed and detected via real-time PCR. All these data were analyzed at the T0 (beginning of the treatment) T1 (1-month) and T2 (3 months); and statistically compared using the Mann-Whitney test for independent groups.
resultsAfter 1-month and after 3 months of treatment there was only one sample with periodontopathic anaerobes found in patient treated using fixed orthodontic appliances. The Invisalign(®) group showed better results in terms of periodontal health and total biofilm mass compared to the fixed orthodontic appliance group. A statistical significant difference (P < 0.05) at the T2 in the total biofilm mass was found between the two groups.
conclusionPatients undergoing orthodontic treatment with the Invisalign(®) System show a superior periodontal health in the short-term when compared to patients in treatment with fixed orthodontic appliances. Invisalign(®) should be considered as a first treatment option in patients with risk of developing periodontal disease.
