Introduction
In 2000, the International Dental Federation (IDF) proposed the concept of minimally invasive intervention in the treatment of caries. Since then, the treatment of caries in posterior teeth has included the use of direct composite resin. However, the moisture
of the oral environment hinders adhesion to the tooth and between resin layers. Furthermore, blood contamination of the surface can also inhibit bonding with the tooth structure. Due to this, it is suggested to use methods to control saliva during the
restorative procedure and one of the most effective measures is Absolute Isolation (AI). In the IA for class I, II, III, IV or V restorations, it is necessary to simultaneously expose the adjacent teeth in order to recover the contact point, whereas the use of IA in Endodontic Treatment (ET), only the tooth to be treated is exposed.
One of the main concerns of dental surgeons and patients is the longevity of dental treatments. The IA was introduced in 1864 in New York City by Sanford C. Barnum, and since then has been used in dental procedures, being one of the most effective means of salivation control, infection control, and patient protection. This strategy also provides better visibility of the region and ideal conditions for handling materials and instruments.
The use of the Rubber Dike (DB) during TE procedures is considered the essential standard by several professionals, including the American Association of Endodontists.14,15 This is due to its function as a barrier to prevent oral pathogens from entering the accessed tooth and prevention of inhalation of instruments and irrigating solutions, taking into consideration that
dentistry is a clinical profession that is associated with biological, chemical and physical risks. Cases of swallowing or aspiration of instruments into the gastrointestinal tract or lung during TE treatment have been reported. These accidents can be avoided by the use of rubber dam isolation.
