The use of Rubber dam has improved operative dentistry in many ways. A drier field, better visibility and access, increase patient comfort, and infection control are only a few of the many advantages of using a rubber dam.
How is Rubber Dam placed?
Placement of rubber dam on a regular basis is an additional step that requires skilled, well trained Dentists. The dam is held over individual teeth or groups of teeth by appropriate rubber dam clamps over the anchor tooth. The tooth crown stands out from the rubber dam through individual holes made by a hole punch, isolating the tooth to be treated from the rest of the person’s mouth which keeps the tooth dry and reduces risk of exposure to oral micro-organisms. The patient can breath and swallow normally, or a saliva ejector may be used if necessary.
Why us rubber Dam?
- Clean and dry operating field. To prevent saliva interfering with the dental work (e.g contamination of oral micro-organisms during root canal therapy, or to keep filling materials such as composite dry during placement and curing). This helps achieve maximum bond strength between restorative material, enamel and dentin.
- There is improved visibility and field of vision, as lips and cheeks are retracted and isolated, as well as fogging of the intra-oral mirror is reduced or eliminated.
- Reduces the chance of swallowing or inhaling instruments, irrigants and materials.
- Improved Patient safety as it helps protect patient’s soft tissues from sharp instruments or materials. Some patients feel safer separating the dental materials and instruments from the rest of the mouth.
