Effect on caries and gingivitis of a preventive program based on oral hygiene measures and fluoride application

Abstract

The present investigation was performed to estimate the effect on caries and gingivitis of a plaque control program delivered at different intervals and supplemented with different fluoride compounds. The study ran for 2 years and was completed by 260 children who were 13-14 years old at the beginning. Professional tooth cleaning in combination with detailed oral hygiene instructions repeated once a month or every 3 months significantly improved their oral hygiene status and reduced clinical signs of gingivitis. The addition of fluoride (NaF or MFP) in mouthrinses and toothpastes significantly reduced the number of new carious lesions. No significant differences were observed in gingival health and caries activity between the programs delivered once a month and every 3 months.
