Another study related awareness of denture cleaning to socioeconomic status and disease, while variations were also found by sex, with women found to clean their dentures more than men. However, in general, a lack of knowledge was often found among patients, with a general understanding that “I should do something,” but with methods being variable. Often, patients reported never having been instructed by their dentists as to how to clean their dentures.Many studies have looked at the efficacy of a range of cleaning products or methodologies, including those specifically designed for use with dentures. Other oral care products (toothpastes, mouthwashes) through to soaps, dishwashing liquids, and bleaches have also been studied. However, in terms of evaluating the relative merits of various denture cleaning regimens, few articles are mentioned in the scientific literature. As a result, the recommendations of professional bodies are relatively limited. For example, the American Dental Association (ADA) recommends not using toothpaste because it can be too harsh for cleaning dentures, although “some people use hand soap or mild dishwashing liquid to clean their dentures, both of which are acceptable. However, most household cleaners are too abrasive and should not be used for cleaning dentures”. Although the need for professional recommendations on appropriate denture cleaning is clear, little is available in the way of national or international guidelines for dental health care professionals (DHCPs) on the most appropriate, evidence-based methods of cleaning dentures effectively. A data collection exercise by a manufacturer of oral health care products (GlaxoSmithKline) showed that in 10 countries in Europe, North and South America, and Asia, the majority of professional bodies did not make specific recommendations on denture cleaning (data on file). When made, recommendations usually focused on the use of either brushes designed specifically for dentures or soft brushes. There was some mention of avoiding abrasives. While denture cleanser tablets were mentioned, a number of bodies recommended dishwashing soap or vinegar. Most web site information seemed not to be evidence-based. Furthermore, where recommendations were found, they were often too vague to help the consumer select a suitable product.
Many chemotherapeutic interventions recommended are effective against planktonic oral bacteria, but unfortunately live intact biofilms are able to persist even after treatment with sodium hypochlorite. These studies taken collectively suggest that denture cleansing is important, but more difficult to achieve than previously thought (Mainieri VC, Beck J, 2011).
DHCP recommendations and denture wearer habits are diverse, with no consensus on the most appropriate denture cleaning methods. This reflects a lack of clear, systematic evidence upon which to base recommendations.
