Rubber dam
In the dentistry , a used rubber dam (correctly cofferdam of English coffer ',' Panel ', waterproof structure (in shipbuilding) and dam , dike', insulation 'also dam of rubber , rubber' Synonyms: Kofferdamtuch , tension rubber ) for shielding of the tooth to be treated from the rest of the oral cavity , especially in the case of a root canal treatment , a plastic filling , a ceramic insert filling or an amalgam removal. This prevents the inflow of saliva . The rubber dam is usually made of elastic plastic or rubber . In addition to shielding the oral cavity for easier saliva-free treatment of the opened tooth, it also prevents foreign bodies from being swallowed or inhaled.
history
The rubber dam was introduced into dentistry in 1864 by the New York dentist Sanford Christie Barnum . The term was borrowed from hydraulic engineering . Originally it was used to keep the work area dry, as there were no dental suction systems at that time . With the spread of suction systems in the 20th century, the acceptance of the rubber dam by dentists decreased and its advantages were forgotten.
Advantages and disadvantages
The disadvantages of the rubber dam are discomfort due to the compressive stress of the metal brackets on the tooth and the risk of traumatizing the gums. As long as the rubber dam is in place, the patient cannot close his mouth. Unrestricted nasal breathing is a prerequisite for working with a rubber dam.
The rubber dam prevents aspiration and swallowing of small parts during treatment, such as amalgam residues , crown residues , pathogens, liquids or instruments for root canal treatment . It is a useful alternative to securing instruments with chains or dental floss.
With the rubber dam technique, the absolute drainage of areas under the gingival margin is possible. This is achieved by adapting the rubber dam clamp to the individual root cross-section and, by displacing the gums, enables the treatment of areas that are not visible below the gums without a rubber dam. This procedure has a high potential for trauma to the gums. When using the adhesive technique , absolute drainage is recommended for the permanent bond between tooth substance and restoration material.
The rubber dam prevents contact with irritating or allergenic substances, such as those used in root canal treatment or adhesive technology. According DGZMK a rubber dam is to take place at each session of a root canal treatment, if not overriding medical reasons (eg. As allergies , asthma , airway 's obstruction , epilepsy ) prohibit this. On the other hand, no need is seen to require mandatory application.
The rubber dam is of particular importance in reducing the aerosol load in the context of dental therapy, as both the amount and the germ load of the aerosol produced are significantly lower. Therefore, it plays an important role in the treatment of patients with diseases that are transmitted via droplet infections.
