1 · What the graph read from 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.

2 · The registry

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

objectiveThe goal of this systematic review was to verify whether the gingival phenotype (thick or thin) could impact the dental implant survival rate by affecting the marginal bone.

methodsThe search was carried out on PubMed/MedLine, PubMed Central, and B-On databases. The research question was: "Does gingival phenotype positively or negatively influence marginal bone loss around dental implants?" The inclusion criteria were: any clinical trial/study, comparative study, prospective or retrospective articles, systematic review that addressed at least a 1-year follow-up with an assessment of the marginal bone loss (MBL) around dental implants, articles that reported the gingival phenotype (thin or thick) and were published in the last 13 years. The exclusion criteria were narrative or other reviews, letters to the editor, and commentaries. Data extraction included the author's name, year of publication, type of study, sample size, number of implants, method used, and outcomes presented. The extracted data was summarized and presented in the results section. Critical Appraisal tool in JBI Systematic Reviews was used to determine the possibility of bias.

resultsA total of 62 articles were found, but eight articles were relevant to compose this study. After deep evaluation, it was possible to observe the implant success rate for both gingival phenotypes, thin and thick, was greater than 91% within a follow-up of up to 5 years. Therefore, it is unclear whether the thickness of the gingival tissue surrounding the implant can directly influence the marginal bone level. The gingival phenotype may be indirectly involved in the survival rate of dental implants, as it can be a risk factor for peri-implantitis, leading to marginal bone loss beyond what is expected. DISCUSSION: The thin gingival phenotype is one of the main risk factors for additional bone loss. It is crucial to know how to preserve the healthy condition.

conclusionWithin the results found, the gingival phenotype is indirectly related to implant survival rate and clinical parameters, which were respectively high and non-conclusive. Therefore, a higher risk of peri-implantitis is suggested when a thin phenotype is present.
