Prevention and Arrest of Root Caries Lesions with High Fluoride Concentration Mouthwash Versus Normal Fluoride Concentration Mouthwash in Elderly Patients: a Randomized, Double-blind Controlled Trial.
Prevention and Arrest of Root Caries Lesions with High Fluoride Concentration Mouthwash Versus Normal Fluoride Concentration Mouthwash in Elderly Patients: a Randomized, Double-blind Controlled Trial.
The study evaluats the effectiveness of regular fluoride 220 ppm F with erythritol and high fluoride 500 ppm F with erythritol mouthwashes against a placebo (regular fluoride 220 ppm F mouthwash) in the prevention of new root caries lesions.
Preserving natural teeth becomes essential to avoid complex restorative procedures in old age. For this the concepts of preventive treatment constitute an important point. The method of topical application via fluorides is a widely used and well-known technique for prevention of caries. Numerous studies have demonstrated the preventive effect of fluorides on caries. The prevention of root caries and the effectiveness of fluorides will depend mainly on two factors used: first is the fluoride agent, and the second is fluoride content. There is abundant evidence with regard to the preventive effect of high fluoride applications on the root caries. Furthermore, it has also been recommended on the regular use of high fluoride 5000 ppm F toothpaste twice daily in the prevention and inactivating the root caries in adults. However, high fluoride toothpastes are fairly expensive and not available as over-the-counter (OTC) products and require a prescription. This may be an aspect when the elders have limited access. A more economical solution and one which can be easily procured is deemed necessary.
Mouth rinses are considered as cosmetic products and are available as OTC products and do not require prescriptions. They are also relatively less expensive in comparison to the high fluoride toothpastes. Fluoridated mouthwashes are generally recommended in moderate-high caries risk population or individual. The normal fluoride range in a mouth wash is normally between 100 ppm to 500 ppm F. This may not be sufficient to bring a preventive effect in high risk individuals. It has been demonstrated that a small positive trend for sodium fluoride (NaF) mouth rinses against placebo in reducing the initiation of coronal and root caries.
Erythritol is a natural sugar substitute and is frequently used as a sweetener. It is easily excreted by the kidneys and does not increase the blood sugar. It is often an additive in mouthwashes as a sweetening agent. It is known to have anti-plaque aggregating and bacteriostatic effect.
Perhaps, the use of erythritol in regular fluoride mouthwash (220 ppm F) in combination with high F mouthwash (500 ppm F) might be beneficial and augment the preventive effect of fluoride in mouth rinses. This may be a viable alternative to expensive and prescription options.
Therefore, the primary objective of this study is to evaluate the effectiveness of regular fluoride 220 ppm F with erythritol and high fluoride 500 ppm F with erythritol mouthwashes against a placebo (regular fluoride 220 ppm F mouthwash) in the prevention of new root caries lesions.
The secondary endpoints/outcome set for this study is the number of arrested root surface caries after intervention with the test products (i.e., a change of root surface caries from ICDAS classification 1 to 2 and 3 to 4, respectively will be considered as arresting).
The tertiary endpoint/outcome set for this study are as follows: 1. Incidence of new coronal caries after the intervention with the test products and 2. the number of arrested coronal caries after the intervention with the test products.
