Statistical analysis
All data were analyzed using the SPSS statistical software version 23.0. The enumeration data were calculated dziąsłoas number/percentage (n/%). The comparison was exploited using the chi-square test. The measurement data were expressed as mean ± standard deviation. T-test was exploited for the intergroup comparison. The difference was statistically significant when the P value was less than 0.05.
Results
As shown in Table 1, there were no differences regarding gender, age, course of disease, underlying disease, index of bleeding, degree of deep overbite, and anterior teeth displacement between the two groups (all P > 0.05).
As shown in Tables 2-4, before treatment, there were no statistical differences between two groups in term of bleeding index, alveolar bone height, anterior tooth coverage, periodontal pocket depth, probing depth, clinical crown length, tooth root length, and inflammatory cytokines levels. After treatment, there were obviously statistical differences between the two groups regarding the bleeding index, alveolar bone height, anterior tooth coverage, periodontal pocket depth, probing depth, clinical crown length, and inflammatory cytokines levels (all P < 0.05). No difference was found in tooth root length between the two groups. In addition, the orthodontic satisfaction of patients in the experimental group was significantly higher than that in the control group.
Also, there was a significant difference between [...]
