Description
Four D Biodam Latex-Free Dental Dam gives latex sensitive patients and staff the Biodam format in a violet synthetic polyisoprene sheet. Four D Rubber promotes the violet color for the enhanced contrast it provides against the teeth. Each box holds 20 of the 6 by 6 inch sheets in a medium or heavy gauge.
- Performs Like Natural Rubber – The manufacturer’s literature says the polyisoprene sheet performs like natural rubber without the potential allergen of latex proteins.
- Violet Contrast Color – The violet shade provides enhanced contrast to the teeth during placement and treatment.
- 1100 Percent Elongation – The sheet stretches further than the line’s latex version before breaking.
- Standard 6 by 6 Inch Format – Twenty sheets per box in the size most operatories already stock.
Latex Free Isolation With a Natural Rubber Feel
Biodam Latex-Free is the polyisoprene member of Four D Rubber’s Biodam family, made for operatories that have removed natural latex from the shelf. The synthetic polyisoprene material is not made with natural rubber latex, and its published elongation at break of 1100 percent exceeds the latex sheet in the same line. Tensile strength is rated at 12.0 MPa with a tear strength of 24 N/mm, giving the sheet the toughness day to day isolation demands. The violet sheet color stands out against enamel, which helps the clinician track the dam edge during placement. Both gauges come in the 6 by 6 inch size with 20 sheets per box.
Features and Benefits
Latex Free Material
- Synthetic Polyisoprene: Not made with natural rubber latex, so the sheet suits patients and team members with latex sensitivity.
- Natural Rubber Performance: Four D Rubber positions the sheet as performing like natural rubber, without the potential allergen of latex proteins.
Visibility and Stretch
- Violet Contrast: The violet color provides enhanced contrast to the teeth, as the manufacturer states in its dam literature.

Why Choose Four D Biodam Latex-Free?
Removing latex from an operatory usually means learning a new dam and a new feel. Biodam Latex-Free keeps the Biodam name, the standard sheet size and the gauge logic, so the switch costs the team nothing in retraining. The violet sheet also reads clearly against the tooth, which speeds up placement checks.
- No Latex, No Workaround – A true polyisoprene sheet removes the allergy question from the setup instead of managing around it.
- Stretches Further Than Latex – At 1100 percent elongation, the sheet tolerates clamp placement that would stress a stiffer film.
- Contrast You Can See – The violet shade stands out against enamel, so the dam edge is easy to verify at a glance.
