A non-latex dam that contains a synthetic, elastomeric material is also available. Elastic bands on face masks also have been shown to contain some latex. As a result, recent generations of products have sought to eliminate this component, primarily affording less chance for adverse reactions on the part of the provider wearing the mask. As more latex-allergic patients are coming into health care facilities for treatment, this question is being considered on many fronts. While facilities are working to provide patients with operating rooms and other treatment areas that are as latex-free as possible, these same hospitals, clinics, and practices are also implementing a number of preventive steps to reduce the total exposure to latex allergens.
Many precautions described are applicable to dental practices as well as medical patient care areas.
Most of the clinical dermatitis problems reported by HCWs have nonspecific, irritant etiologies. These can develop from a variety of sources, such as contact with a substance that physically or chemically damages the skin, frequent hand washing with antiseptic agents, effects of the antiseptics on sensitive skin, failure to completely rinse off hand antiseptics, excessive perspiration on hands while wearing gloves, and failure to dry hands thoroughly. Unfortunately, because a number of participants in latex allergy surveys do not undergo specific testing to confirm a suspected diagnosis of latex hypersensitivity, qualifying statements are included in some reports. These problems are gradually being addressed by using better investigation protocols and including specific assays that can assist in establishing a latex hypersensitivity diagnosis. One case in point is the inclusion of the latex skin test in the Health Screening Program conducted at ADA annual sessions.
