The influence of fixed prosthesis placement on the clinical effectiveness of non-surgical periodontal therapy.

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
Background/purpose: Fixed prostheses are essential for restoring teeth with compromised structures. However, the margins of prosthesis potentially create an interface that interferes with proper cleaning. This study evaluated whether the fixed prosthesis placement influenced the clinical effectiveness of non-surgical periodontal therapy (NSPT). Materials and methods: Clinical records from 202 patients with generalized chronic periodontitis receiving NSPT at the National Taiwan University Hospital in 2012-2014 were included. The change and improvement ratio (IR) of clinical parameters following NSPT in the entire dentition or posterior region, and all or periodontitis-affected teeth/crowns (T/C) and sites were evaluated. The differences among natural teeth (NT), prosthetic crowns (PC), and abutments (AB) were compared by using Kruskal-Wallis tests followed by Dunn's post-hoc test. Results: Gingival recession (REC) was greater in PC and AB groups than in the NT group before NSPT, while tooth mobility was also lower in the AB group. REC gain was lower in the AB group after NSPT, while mobility reduction was inferior in the PC and AB groups for all or periodontitis-affected T/C and sites. In periodontitis-affected T/C, IRs in probing pocket depth reduction and clinical attachment gain were lower in the PC group, and mobility reduction was lower in the AB group. The tendency in the posterior region is similar but was less pronounced than in the entire dentition. Conclusion: The effectiveness of NSPT and the improvement of periodontal parameters are reduced when fixed prostheses present. MB reduction is inferior in AB teeth relative to NT.
