NCT02647203

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

Outcome Measures

Primary Outcomes (1)

  • Root Caries Activity

    Using Nyvad's criteria for root caries lesions, activity will be assessed by a visual-tactile method.

    After 2 years of follow up

Secondary Outcomes (2)

  • Oral Health Related Quality of Life, Measured by the Oral Health Impact Profile (OHIP-14 Sp)

    Data registered at 2 years of follow-up

  • Salivary Flow

    Baseline and 2-year follow up

Study Arms (2)

High Fluoride Toothpaste

EXPERIMENTAL

5,000 ppm fluoridated toothpaste, high concentration. Self-administered fluoridated dentifrices. By the elderly subjects, twice per day Drug (including placebo)

Drug: Self-administered fluoridated dentifrices

Standard Fluoride Toothpaste

ACTIVE COMPARATOR

1,450 ppm fluoridated toothpaste, low concentration. Self-administered fluoridated dentifrices. By the elderly subjects, twice per day Drug (including placebo)

Drug: Self-administered fluoridated dentifrices

Interventions

Elderly participants will be instructed to self administer toothpastes, twice per day. Toothpastes will be provided.

Also known as: Toothbrushing with high and standard fluoride dentifrices
