Background
To determine the relationship between clinically significant tooth size discrepancies (TSD) and archform classification in orthodontic patients.
Material and Methods
Eighty teeth with artificial white spot lesions were randomly divided into four groups: (A) distilled and deionized water, (B) Nd:YAG laser, (C) CPP-ACP crème, & (D) CPP-ACP plus laser. SMH was measured using Vickers diamond indenter in Vickers Hardness Number (VHN). Two samples of each group were analyzed using scanning electron microscope (SEM). The results were analyzed with the SPSS 17/win.
Results
Reproducibility of the classification of archform was very good (unweighted Kappa statistic of 0.83 with a 95% …
