. The purpose of this study was to evaluate the effects of a magnetized water oral irrigator on plaque, calculus and gingival health, 29 patients completed this double‐blind crossover study. Each patient was brought to baseline via an oral prophylaxis with a plaque index ≤1 and a gingival index ≤1, Subjects used the irrigator for a period of 3 months with the magnet and 3 months without the magnet. After each 3 month interval, data were collected using the plaque index, gingival index, and accretions index. The repeated measures analysis on plaque, gingival and calculus indices yielded a statistically‐significant period effect for Pll (p=0.0343), GI (p=0.0091), and approached significance for calculus (p=0.0593). This meant that the effect of irrigation resulted in a decrease of all indices over time. Therefore, the treatment effect on each index was evaluated using only the measurements obtained at the end of the first period (i.e., assuming a parallel design). Irrigation with magnetized water resulted in 64% less calculus compared to the control group. The reduction was statistically significant (p≤0.02). The reduction by 27% in gingival index was not statistically significant. The reduction in plaque was minimal (2.2%), A strong positive correlation between the plaque index and the Watt accretion index was observed. The magnetized water oral irrigator could be a useful adjunct in the prevention of calculus accumulation in periodontal patients, but appears to have minimal effect on plaque reduction. The results indicated a clinical improvement in the gingival index, but this was not a statistically significant finding.
