Overall score: possible score 0-10 based on a VAS-scale; crown index score: possible score 0-1; mucosa index score: possible score 0-1. Score is ranked acceptable when: overall score = 6-10; crown score = 0; mucosa score = 0. * Overall significance was calculated with the Kruskal–Wallis test. **Significance between two follow-up periods were calculated with the Wilcoxon signed rank test.
