Effect of different brushing parameters on erosive tooth wear in primary bovine enamel and dentin

by Philipp Kanzow, Corinna Witt, Clemens Lechte, Sarah Barke, Bianca Rohland, Alexandra Schmidt, Annette Wiegand This in-vitro study aimed to analyse the effect of brushing and different brushing parameters (kind of toothpaste, kind of toothbrush, brushing force) on erosive tooth wear of primary bovine enamel and dentin. Specimens were prepared from primary bovine enamel or dentin (each group n = 12) and cyc lically eroded (6 × 60 s/d, citric acid, pH 2.4) and brushed with children’s toothbrushes (2 × 15 s/d) over 5 days. The brushing parameters under investigation were: toothpaste (fluoridated, fluoride-free), toothbrush (manual; rotating-oscillating and sonic, each at two different activation mode s) and brushing force (1 N, 2 N). Specimens that were only eroded and not brushed served as controls. Enamel and dentin wear was quantified using widefield confocal microscopy. Statistical analysis was performed using three- and one-way ANOVAs followed by Scheffe’s (enamel) or Tamhane’s (dentin) post-hoc tests (p
