Brief Summary:
This study aims to test the effectiveness in reducing or arresting root caries lesion in community-dwelling elderly subjects by using high fluoridated toothpaste. A double blinded RCT will be conducted with two arms; 5000 ppm F and 1450 ppm F toothpaste. Dentifrices will be delivered to the participants in a blind format and they will be instructed to brush twice per day.
Follow-up will be carries out every 6 months for two years to assess:
* Root caries incidence.
* Lesion arresting
* Changes in salivary flow
* Microbiology pattern shift
* Variations in oral health- related quality of life by OHIP-14 Sp

Detailed Description:
Background. Caries of the root surface (root caries) is the most prevalent type of dental caries in older adults with a reportedly worrisome trend to increase, as more teeth are being retained. Dental caries is the leading causes of tooth loss among older adults. Fluoride has been successfully used in preventive programs for root caries. In addition to preventing root caries, fluoride-based therapies may be used to treat lesions. This approach is known as non-invasive treatment. Fluoride seems to arrest and promote remineralization of the lesions. Indeed, recent studies appear to indicate that, higher fluoride concentrations are more effective to prevent and to treat the disease. Dentifrices with high concentrations of fluoride appear to be the most rational approach to prevent and treat root caries. To the chemical effect of fluoride, toothbrushing adds mechanical removal of the dental biofilm. High concentration fluoride varnishes have also been proposed as effective in treating carious lesions. Whether dentifrices, varnishes or the combined use of varnish and fluoridated toothpaste result more effective is a matter of controversy and it needs to be elucidated. Non-invasive treatment avoids the complications inherent to treating frail people in a dental setting, decrease costs and importantly, allows increased coverage, as these therapies may be delivered by non-dentist personnel. Although the appealing idea of non-invasive treatment of root caries in older adults, evidence is still limited and more research appears necessary to both, confirm clinical success and elucidate the mechanisms involved in lesion arrestment.
Aim. To determine the effectiveness of non-invasive therapies for root caries and their impact in the quality of life of older adults.
Methodology. A double blind randomized controlled trial (RCT) on independently-living older adults aged sixty or more years is proposed. Subjects will undergo clinical and microbiological examination when recruited (baseline) with a six-month follow-up regime until completion of two years. To participate, subjects will have to have at least five teeth with exposed root surfaces and one carious lesion. Sample size was calculated and a sample of two-hundred and eighty-eight older adults is necessary, randomized into two study arms;
Group 1: toothpaste 1.450 ppm F-
Group 2: toothpaste 5.000 ppm F-
Dependent variables. Root caries incidence and activity, cariogenic bacteria and oral health-related quality of life will be assessed upon completion of the study and compared with baseline scores.
Expected results. Based on some previous data available, it is expected that a non-invasive therapy for root caries based on low-fluoride concentration will be less effective than high fluoride therapies in inactivating root caries lesions. These results may be used in novel therapeutic programs at the community level, as well as in private practice. Furthermore, these studies will shed light on potential mechanisms associated with non-invasive treatment of root caries, from a microbiology stand point. Since a non-invasive approach decreases costs and increases coverage of dental care for older adults, these results may contribute to increase access to care for the usually vulnerable population of older adults.
