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 not repl...
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 and lower ...
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 system...
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).

Search result: Two systematic reviews and 5 additional trial reports were found. Clinical outcomes: While the trial reports indicate no significant difference, the systematic reviews suggest 2-step systems to be superior to 1-step systems.

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.

Search result: 2 systematic reviews and 9 clinical trials were found. Clinical outcomes: The results suggest MTA to be effective for pulp capping.

Search result: 7 trials were found. Clinical outcomes: The results suggest that various composites (nanohybrid, flowable) show good results. Etch-and-rinse adhesives appear to be superior to all-in-one adhesives, while compomers and resin-modified glass-ionomers appear to be less effective than composites. [‘Preliminary Systematic Literature Searches’ are based on SYSTEM’s periodic systematic searches of the dental literature and provide first overviews over existing clinical evidenc...
Search result: 5 trials and 6 systematic reviews were found. . Clinical outcomes: The results suggest that: (i) for lithium disilicate single crowns, the existing evidence indicates excellent short-term survival rates, but the evidence for medium-term survival is limited; (ii) for lithium disilicate fixed dental prostheses, the evidence for short-term survival is fair, although limited, but the evidence for medium-term survival is not promising; (iii) there is contradicting evidence whether...
Search result: 11 trials were found. Clinical outcomes: The results suggest that stannous ions may have a caries/demineralisation preventive effect (particularly when stannous fluoride was compared to sodium fluoride).

Search result: 5 trials were found. Clinical outcomes: The results of the laboratory trials appear contradictory particularly when stannous fluoride was compared to sodium fluoride).

Search result: 9 trials were found. Clinical outcomes: The results of the mainly laboratory trials suggest that stannous ions have an inhibiting effect on oral bacteria (particularly when stannous fluoride was compared to sodium fluoride).

Search result: Only trials with low-viscosity GIC were found. Clinical outcomes: The results suggest that cervical restorations placed with chemically cured GICs have good survival rates when compared to composite but are less aesthetic.

Search result: No clinical evidence concerning adverse effects of aluminium, barium or strontium released from GICs were found. Clinical outcomes: A review of the relevant laboratory literature, including a conservative calculation of any potential adverse clinical effect due to aluminium content, concludes that the amount of aluminum that could be leached into the body from glass-ionomer dental fillings is well below the permitted daily dose and almost certainly too small to have a measu...
