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.[‘Preliminary Systematic Literature Searches’ are based on SYSTEM’s periodic systematic searches of the dental literature and provide first overviews over existing cli...

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...

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.[‘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 r...

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..[‘Preliminary Systematic Literature Searches’ are based on SYSTEM’s periodic systematic searches of the dental liter...

How do Composite (CAD/CAM) crowns compare to ceramic crowns in terms of clinical restoration survival? [November 26, 2017]

Search result: One clinical trial was found.Clinical outcomes: The results suggest that Composite (CAD/CAM) crowns are inferior to ceramic crowns after 3 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 assessment of precision and internal validity of results and thus do no...

How do Fibre posts compare to Metal posts in terms of clinical restoration survival? [November 25, 2017]

Search result: Two systematic reviews and two additional trial reports that were not covered by the systematic reviews were found.Clinical outcomes: The older systematic review (2005) included only one relevant trial not included in the other more recent systematic review (2014) and stated higher failure risk for metal-posts. However, the more recent systematic review included 14 trials and found no significant differences. In addition, one trial indicated higher fracture risk ...

How do 2-step etching systems compare to 3-step etching systems in terms of clinical restoration survival? [November 20, 2017]

Search result: Two systematic reviews and one additional trial reports were found.Clinical outcomes: While the trial report and one systematic review indicated no significant difference, one other systematic review suggests 3-step systems to be superior to 2-step systems for composite restorations in cervical cavities and inferior for composite restorations in load-bearing cavities of permanent teeth.[‘Preliminary Systematic Literature Searches’ are based on SYSTEM’s periodic ...

How do 1-step etching systems compare to 3-step etching systems in terms of clinical restoration survival? [November 18, 2017]

Search result: Two systematic reviews and one additional trial report were found.Clinical outcomes: While the trial report indicated no significant difference, one systematic review provided no data while the other indicated that 3-step self-etching systems to be superior to 1-step self-etching systems (no information were provided for 3-step versus 1-step etch-and-rinse systems).[‘Preliminary Systematic Literature Searches’ are based on SYSTEM’s periodic systematic searches o...

How do HEMA free bonding agents compare to HEMA containing bonding agents in terms of clinical restoration survival? [November 16, 2017]

Search result: Three studies were found.Clinical outcomes: The result indicates no differences between HEMA containing and HEMA-free bonding agents for most clinical outcomes after 3 and 5 years. In addition, restorations with HEMA-free agents appear to have some higher dentin retention after 5 years, while exhibiting more incisal marginal defects and discolorations after 3 years.[‘Preliminary Systematic Literature Searches’ are based on SYSTEM’s periodic systematic searches o...
