Abstract
ABSTRACTBackground: Stannous fluoride is a broad-spectrum antimicrobial agent. It has been incorporated into dentifriceformulations and shown to be effective in the prevention and reduction of gingivitis (17, 18, 20). The aim of this study wasto determine whether conventional tooth brushing and twice daily use of a brush on 0.4% stannous fluoride (SnF2) gelwould be more effective for controlling plaque accumulation and gingivitis than conventional tooth brushing alone.Materials and Methods: A randomized, six month, examiner blind. Gingivitis study conducted according to the guidelines for evaluating chemotherapeutic products for the control of gingivitis. Stannous fluoride gel (0.4 %) was testedagainst a commercially available negative control dentifrice (Crest Complete, KSA). The sample of the studyincluded two groups, the first; control group (N=30) used tooth brushing with standard fluoride tooth paste( CrestComplete ,KSA),while the second; study group (N=30) used tooth brushing with the same tooth paste,supplemented with a 0.4% stannous fluoride gel used twice daily for the entire six month-study period. Clinicalassessment involved plaque index(1) gingival index(2) and bleeding on probing index(3) were performed at base line,three and six months post-treatment.Results: The stannous fluoride gel (SnF2) group had significant lower scores for plaque index (PL.I, p< 0.05), gingivalindex (GI, p< 0.05) and bleeding tendency at all examinations than did the control group. For the study group, meanbaseline PL.I score was 1.83, at three months it was reduced to 0.84and after six months it was 0.54. For the GI. Meanbaseline GI. was 1.60, at three months it was 0.82 and after six months it was reduced to 0.57.For Bop, score (1) wasrecorded in (29.11%) for the study group at base line. After three months, score (1) was reduced to 16.2%, thedifference is significant (p< 0.01) in comparison with the control group. After six months, the percentage was 13.76%.The difference between the two groups significant (p< 0.05).Conclusion: It is concluded that the use of 0.4% SnF2 gel is an effective adjunct to mechanical tooth cleaning indecreasing plaque and gingivitis.Key words: Stannous fluoride, plaque, gingivitis.
