Retention of GIC versus Amalgam as restorations [October 11, 2018]
Search result: There is still a lack of studies to this topic and only two clinical studies concerning restorations in the primary dentition were found. Clinical outcomes: The results of (conventional) high-viscosity GIC indicate no difference to amalgam while, low-viscosity GIC perform significantly worse than amalgam.

Longevity of resin-modified GIC versus compomers in primary teeth [October 10, 2018]
Search result: Only three clinical studies were found. Clinical outcomes: The results indicate no difference in the longevity between both types of materials. [‘Preliminary Systematic Literature Searches’ are based on SYSTEM’s periodic systematic searches of the dental literature and provide first overviews over existing clinical evidence but are limited in the number of databases searched, as well as the assessment of precision and internal validity of results and thus do not replace t...
Cariostatic effect of conventional GIC versus composite resin [October 10, 2018]
Search result: Eight clinical studies to topics concerning orthodontic bonding, root- and tooth restorations were found. Clinical outcomes: The results indicate a higher cariostatic effect of GIC for orthodontic bonding and tooth restorations in permanent teeth. No difference was found for tooth restorations in primary teeth when compared to fluoride containing composite and root restorations. [‘Preliminary Systematic Literature Searches’ are based on SYSTEM’s periodic systematic sear...
Coating of high-viscosity GIC [October 09, 2018]
Search result: Three prospective clinical controlled trials were found. Clinical outcomes: The results indicate that there may be a trend that coating can protect Fuji IX GP Extra against wear.

Cariostatic effect of conventional GIC versus compomers [October 09, 2018]
Search result: Five clinical trials were found and traced. Clinical outcomes: The results are conflicting or suggest no difference between conventional GIC and Compomers in regard to their anticariogenic effects after 3-4 years. [‘Preliminary Systematic Literature Searches’ are based on SYSTEM’s periodic systematic searches of the dental literature and provide first overviews over existing clinical evidence but are limited in the number of databases searched, as well as the assessmen...
Cariostatic effect of resin-modified GIC (RM-GIC) versus compomers [October 08, 2018]
Search result: Twelve clinical trials were found and traced. Clinical outcomes: The overall results suggest no difference between RM-GIC and Compomers in regard to their anticariogenic effects.

Antibacterial effect of GIC versus composite resin [October 08, 2018]
Search result: One clinical trial was found and traced concerning resin-modified GIC (RM-GIC). Clinical outcomes: The material was Fuji II LC (compared to: Tetric Flow and Helioseal F). No trials were identified comparing conventional GIC (C-GIC) with composite resin.

Do patients, who have received polytetrafluoroethylene (PTFE) based sutures experience less, similar or more gingival inflammation than patients with polyamid (nylon) based sutures? [June 05,
Search result: No direct clinical data to the topic could be found. Clinical outcomes: However, one systematic review reported that ePTFE sutures cause clinically less inflammation than silk sutures in humans. One animal study (in rabbits) found less general inflammation from ePTFE sutures than Nylon sutures.

What is the clinical bleaching effect of 10 and 15% Carbamide peroxide based products for home use tooth whitening? [November 29, 2017]
Search result: One systematic review and 7 clinical trials were found. Clinical outcomes: The results suggest Carbamide peroxide (CP 10 and 20%) to be more effective in color change than Hydrogen peroxide (HP). In addition, (i) CP 10% appears no more effective than CP 5%, (ii) no difference was observed between CP 10% and CP 15% and (iii) the use of CP 10% appears more comfortable to patients than HP 10%. However, its clinical relevance is unfavourable and potential side-effects of at-home...
What is the clinical merit of bioactive glass in restorative dentistry? [November 28, 2017]
Search result: One systematic review was found. Clinical outcomes: The limited results suggest that bioactive glass may be effective in remineralising dentin.

What are the clinical merits of CAD/CAM manufactured dentures? [November 27, 2017]
Search result: Two older systematic reviews (until June 2012) and one recent clinical trial (2016) were found. Clinical outcomes: The results suggest that CAD/CAM post-sintered denture frameworks are superior to CAM pre-sintered denture frameworks and that CAD/CAM systems may show less marginal discrepancy than conventional methods for framework fabrication..
