abstract: Cagetti MG, Carta G, Cocco F, Sale S, Congiu G, Mura A, Strohmenger L, Lingström P, Campus G; Italian Experimental Group on Oral Health. 2014. Effect of fluoridated sealants on adjacent tooth surfaces: a 30-mo randomized clinical trial. J Dent Res. 93(7 Suppl):59S-65S. (Original DOI: 10.1177/0022034514535808) There was a typo in two confidence intervals (CIs) in the Abstract. Original sentence: Incidence rate ratios (IRRs) were 0.70 (95% confidence interval: 0.50, 0.68; p < .01) for GIC vs. RB and 0.79 (95% confidence interval: 0.53, 1.04; p = .005) for fluoride-RB vs. RB. Corrected sentence: Incidence rate ratios (IRRs) were 0.70 (95% confidence interval: 0.50, 0.86; p < .01) for GIC vs. RB and 0.79 (95% confidence interval: 0.67, 0.89; p = .005) for fluoride-RB vs. RB. There was also a typo in two CIs in the Results section. Original sentence: IRR was 0.70 (95% confidence interval [CI]: 0.50, 0.68; p < .01) between GIC and RB and 0.89 (95% CI: 0.89, 1.28; p = .10) between GIC and fluoride-RB. IRR between fluoride-RB and RB groups was 0.79 (95% CI: 0.53, 1.04; p = .005). Corrected sentence: IRR was 0.70 (95% confidence interval [CI]: 0.50, 0.86; p < .01) between GIC and RB and 0.89 (95% CI: 0.89, 1.28; p = .10) between GIC and fluoride-RB. IRR between fluoride-RB and RB groups was 0.79 (95% CI: 0.67, 0.89; p = .005). In the first CI, the digits were inadvertently inverted. In the second, the reported CI was from another variable not included in the article. The correct CIs are 0.50, 0.86 and 0.67, 0.89.
