Effects of different periodontal splints combined with orthodontic treatment on facial aesthetics in patients with sector displacement of periodontitis teeth / 中国医师杂志

ABSTRACT

Objective:To study the facial aesthetic effect of different periodontal splints combined with orthodontic treatment for patients with sector displacement of periodontitis teeth.Methods:A total of 186 patients with sector displacement of periodontitis teeth admitted to Hunan Second People′s Hospital from April 2018 to April 2020 were prospectively selected as the research objects. 186 patients were divided into observation group and control group by random number table method, with 93 cases in each group. Both groups were treated with orthodontic correction. The observation group was treated with orthodontic combined with super fiberglass periodontal splint, while the control group was treated with orthodontic combined with conventional periodontal splint. The treatment effect, serum inflammatory factors [tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), interleukin-6 (IL-6) ], periodontal pocket depth, bleeding index and plaque index before and after treatment were compared between the two groups, and the satisfaction of the two groups was compared.Results:At half year and 1 year after treatment, the effective rate of the observation group was 91.40%(85/93) and 100%(93/93), which were significantly better than those of the control group [84.95%(79/93), 95.70%(89/93), all P<0.05]. The levels of serum TNF-α, CRP and IL-6 in the two groups at half year and 1 year after treatment were significantly lower than those before treatment (all P<0.05); the levels of serum TNF-α, CRP and IL-6 in the observation group was significantly lower than the control group, with statistically significant difference (all P<0.05). The periodontal pocket depth, bleeding index and plaque index of the two groups after treatment were also significantly lower than those before treatment (all P<0.05); the periodontal pocket depth, bleeding index and plaque index of the observation group was significantly lower than the control group, with statistically significant difference (all P<0.05). At half year and 1 year after treatment, the patients′ satisfaction in the observation group reached 91.40%(85/93) and 94.62%(88/93), respectively, which was also significantly better than that in the control group [81.72%(76/93), 89.25%(83/93), all P<0.05]. Conclusions:Compared with the conventional periodontal splint, the combination of super fiberglass periodontal splint can significantly improve the treatment effect and patient′s satisfaction.
