01..  Dental Dam


High quality Royal Shield powdered and powder free latex dental dams are formulated with superior tearing resistance in mind. Tearing at the punched hole(s) is a major source of frustration for dental health practitioners when isolating the target tooth/teeth during a procedure, but our dam with its superior tear resistance puts paid to that. Extractable latex protein is removed to a level near to its detectable limit for powder free dams. The dams are available in four different gauges and packed in boxes of 36pcs x 6x6 or 52pcs x 5x5. It can also be supplied in 50 metre roll form if so required.
