Title Newly Marketed Low Shrinkage Dental Resin Composites: Filtek LS vs. Venus Diamond For Posterior Occlusal Restoration
Clinical Question Does the use of Venus Diamond have a longer longevity when placed in a posterior occlusal restoration compared to Filtek LS?
Clinical Bottom Line There is laboratory evidence showing that Venus Diamond has superior physical and mechanical properties (lower contraction stress) compared to Filtek LS, which has theoretical implications that Filtek LS would have a longer longevity when placed in a posterior occlusal restoration, there are no current clinical studies that show significant evidence that one composite is recommended over the other.

Comments on
The Evidence
There is no strong evidence that is directly related to comparing Venous Diamond to Filtek LS, nor is there any regarding their use in a posterior occlusal restoration. Furthermore, the search for evidence on the two specific brands of composites does not reveal any matches on PubMed. In order to find the best available evidence, more generic terms had to be used. However, even with the broader terms, the evidence is still does not give any significant clinical answers to whether or not Venous Diamond or Filtek LS have a longer longevity in a posterior occlusal restoration.
Applicability Although a laboratory study supports Venous Diamond as having superior physical properties to Filtek LS, due to the lack of clinical evidence, the potential benefit of using Venus Diamond over Filtek LS for a posterior occlusal restoration is not clear. Thus, the dentist must make an informed decision as to what brand to use based on the particular circumstances of the patient and they should only use the new products for conservative treatments until further clinical evidence is found.

A PubMed search on was done on the comparison between composite resin Filtek LS and Venus Diamond based longevity of posterior composites. There are no new clinical studies comparing the two composites, only laboratory studies - Lee 2013- PMID 24088822 and Heo 2013 -PMID 23240875. Filtek was found to have a higher degree of conversion using the same curing unit. The authors extrapolate this information indicating Filtek LS may potentially last longer due to the higher conversion relating to a higher degree of hardness, less shrinkage of material, and less leakage.
