The use of mouthwashes is widely extended in the elderly population.

Elderly patients use mouthwash to treat periodontal disease, candidiasis, stomatitis, xerostomia, halitosis, or carious lesions.

The most commonly used mouthwashes contain chlorhexidine, fluorides , and essential oils as active ingredients, followed by nystatin.

A higher prevalence of oral problems has been observed in the elderly population. One of the treatment options for some of these pathologies is the administration of mouthwashes combined with mechanical removal techniques. Besides, each type of oral rinse treats certain oral diseases, and it should be selected for each specific situation.

To determine the use and efficacy of mouthwashes in the elderly as a treatment for various pathologies, to indicate the most common kinds of mouth-rinses used, the diseases treated with them, their efficacy in each treatment, and their effectiveness when they are combined with other treatments.

The review has been carried out following the PRISMA 2020 Statement. Individualized bibliographic searches were performed in five databases. Randomized clinical trials are included in patients over 60 years old where mouthwashes were administered to treat or prevent specific diseases. The PICO question aimed to assess what type of mouthwashes elderly patients use, what they use them for, and their efficacy. Study selection, data extraction, and quality analysis were achieved using the RoB-2 guide.

Thirteen articles were chosen to perform the qualitative analysis. The bibliometric analysis was carried out. We have eleven randomized controlled clinical trials and two uncontrolled. The mouthwash more used was chlorhexidine, followed by essential oils and fluorides. The most studied pathologies were a periodontal disease, caries, candidiasis, denture stomatitis, and xerostomia. Chlorhexidine used weekly is effective as antiplaque and antigingivitis. Fluorides effectively prevent and reverse caries; nystatin and essential oils to treat candidiasis; and pilocarpine rinse to manage xerostomia.

The included studies show that mouthwashes are widely extended in the elderly population, and each sort is specifically designed for treating a particular condition.
