Purpose:
To compare the effectiveness of Prevident 5000 Plus (5,000 ppm F) and Colgate Winterfresh Gel (1100 ppm F) to arrest root carious lesions.
Materials And Methods:
201 subjects with at least one root carious lesion were recruited from dental school patients. They were randomly assigned to use either Prevident 5000 Plus (5000 ppm F) or Colgate Winterfresh Gel (1100 ppm F) as sodium fluoride in the same silica base. Measurements of lesion hardness, area, distance from the gingival margin, cavitation and plaque were recorded at baseline and after 3 months by a single examiner.
Results:
After 3 months 38% of subjects using Prevident 5000 Plus and 10% using Winterfresh Gel had one or more lesions that had become hard (P < 0.001). Non-cavitated lesions at baseline were more likely to become hard than cavitated lesions. Compared to the Winterfresh group there was significant increase in the distance from the base of the lesion to the gingival margin and plaque scores were reduced in those using Prevident 5000 Plus.
