Soft tissue attachment of human gingival fibroblasts to titanium dioxide nanotubes compared to commercially pure titanium and its alloys: a systematic review.

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
objectiveThis systematic review was conducted to evaluate the attachment of human gingival fibroblasts (HGFs) of the soft tissue, to titanium dioxide nanotubes (TNTs) compared to commercially pure titanium (cp-Ti) and its alloys, in in-vitro studies. It is postulated that the nanotopography of the TNTs provide cells with a biomimetic environment, allowing HGFs to form more focal adhesion (FA) attachment sites at the tubule edges.
methodA comprehensive literature search was conducted on MEDLINE, DOSS, EMBASE and Google Scholar from January 2012 to January 2022. The identified studies were screened based on titles and abstracts for inclusion criteria. The relevant studies underwent data extraction. The risk of bias was assessed through the Office of Health Assessment and Translation (OHAT) tool.
resultsThis systematic review included four studies evaluating cell proliferation, protein expression, gene expression and cell morphology of HGFs evocative of stronger and mature soft tissue attachment. A significant increase in the cell proliferation at TNTs compared to cp-Ti, at day 7 for three studies and at day 14, for one study was evident. In addition, a significant increase in the type 1 collagen protein expression at TNTs compared to cp-Ti, at day 6 for one study and day 7 for two studies. Enhanced cellular extensions from HGFs attached onto TNTs, compared to cp-Ti was observed in all four studies. All the primary effects evaluated suggest the formation of better interlaced fibers giving a stronger adhesion than the parallel ones which is the most relevant outcome of this research.
conclusionHGFs showed enhanced contact guidance onto TNTs but a true biological attachment was not confirmed. This review involved invitro studies which lack methodological rigor to compare among studies, lack information and have small sample sizes limiting effectiveness of parametric tests. The results may be unpredictable when translated to in-vivo studies mainly affected by confounding factors. Further research is needed to determine the precise mechanism of mechanical attachment between the soft tissue and the transmucosal surfaces.
