- BMH: Horizontal brushing movement, TBA: Toothbrush A, LING: Lingual site, ABS1: Incisors and canines, ABS2: premolars. t-values in parentheses. (*), (**), (***): the null hypothesis “estimated coefficient is not different from zero” can be rejected at a significance level of 10, 5 resp. 1 percent. R 2: coefficient of determination. DW: Durbin-Watson test for autocorrelation of the residuals. BPG: Breusch-Pagan-Godfrey test for heteroscedasticity.
