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.

PubMed ID	Author / Year	Patient Group	Study type (level of evidence)
#1) 21093034	Ferracane/2011	none	Systematic Review
Key results	As stated by the author, “There is no one ideal material available to the clinician, but the commercial materials that comprise the current armamentarium are of high quality and when used appropriately, have proven to deliver excellent clinical outcomes of adequate longevity.”
#2) 20566212	Marchesi/2011	None	Laboratory Testing
Key results	Laboratory findings revealed that Venus Diamond showed the lowest stress values under two different clinical conditions. Stress values scored as Venus Diamond

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.
