Title |
Longevity Of Resin Composites Compared To Glass Ionomers |
Clinical Question |
In a class II restoration, does the benefit of a fluoride releasing restoration such as Fuji more beneficial than the longevity of a resin restoration? |
Clinical Bottom Line |
No, due to the fact that in a class II restoration in the posterior teeth, the strength of a glass ionomer is not as strong as a resin composite. There really are not many types of glass ionomers on the market at the moment, but with time this might be changed. (See Comments on the CAT below) |

Glass ionomers had the highest success rates, but also the fewest studies and fewest restorations with only one product being assessable. | 20638116 | Heintze / 2010 | 36 Clinical Trials which 25 of which were RCTs | Meta Analysis | Key results | Restorations placed in teeth whose dentin/enamel had been prepared showed a statistically significant higher retention rate than those placed in teeth with unprepared dentin (p<0.05). | 10716002 | Downer /1999 | 124 Research Reports | Systemic Review | Key results | Restoration type, materials, the patient, the operator, the practice environment and type of care system appeared to influence longevity. Many studies were imperfect in design. Those considered being the most appropriate for analysis were too limited to undertake a formal statistical exploration. More proper studies need to be correlated in order for a proper result. | |

Comments on
The Evidence |
There was not much research done on the topic since there are limited choices when it comes to glass ionomers. In the future, more research is needed to get a more reliable answer. |
Applicability |
This is not really applicable at the moment because of the limited glass ionomer products available at the moment. |

Comments and Evidence-Based Updates on the CAT
(FOR PRACTICING DENTISTS', FACULTY, RESIDENTS and/or STUDENTS COMMENTS ON PUBLISHED CATs) |
by Colby Richey, Tanner Hunsaker (San Antonio, TX) on 01/06/2014 A search was conducted on PubMed regarding this topic in January of 2014. No evidence to contradict the finding of this CAT was found. The research shown since the day of the published CAT does not give a conclusive answer to the original question. | |
