During fixed orthodontic treatment, the presence of various fixed appliances like brackets in the oral cavity for a long period leads to various changes in the oral microflora, ultimately affecting the periodontal health of the teeth. Hence, the current study was performed to clinically assess the periodontal status of the subjects undergoing fixed orthodontic treatment and to evaluate the role of age and gender during the first 6 months of treatment.
Forty-one subjects (26 females and 15 males) in the age range of 12-28 years scheduled for fixed orthodontic treatment were included in the study. Twenty-eight subjects were adolescents with a mean age of 13.96 years and 13 were adults with a mean age of 22.38 years. Plaque index (PI) and gingival index (GI) were recorded at the beginning and the end of 1, 2, 3, and 6 months of the treatment, and pocket probing depth (PPD) was evaluated at the start and after 6 months of fixed orthodontic treatment.
The study showed a statistically significant increase in the mean values of PI (1.10 ± 0.264) and GI (0.929 ± 0.220) over a period of 6 months when compared with the baseline mean values, i.e., 0.557 ± 0.224 and 0.423 ± 0.329, respectively ( < 0.001). The mean PPD values exhibited no significant change. Effect of orthodontic treatment on adolescents/adults and between genders did not statistically differ.
Fixed orthodontic treatment with multibracket appliances significantly increases plaque accumulation leading to significant inflammatory changes in the gingival tissues without any significant changes in the clinical probing depths of the pockets regardless of age and gender.
在固定正畸治疗期间，口腔中长期存在各种固定矫治器（如托槽）会导致口腔微生物群发生各种变化，最终影响牙齿的牙周健康。因此，本研究旨在临床评估接受固定正畸治疗的受试者的牙周状况，并评估年龄和性别在治疗前6个月中的作用。
本研究纳入了41名计划接受固定正畸治疗的受试者，年龄在12至28岁之间（26名女性和15名男性）。28名受试者为青少年，平均年龄13.96岁，13名受试者为成年人，平均年龄22.38岁。在治疗开始时以及治疗1、2、3和6个月结束时记录菌斑指数（PI）和牙龈指数（GI），并在固定正畸治疗开始时和6个月后评估牙周袋探诊深度（PPD）。
研究表明，与基线平均值（分别为0.557±0.224和0.423±0.329）相比，PI（1.10±0.264）和GI（0.929±0.220）的平均值在6个月内有统计学显著增加（<0.001）。平均PPD值无显著变化。正畸治疗对青少年/成年人以及不同性别之间的影响在统计学上无差异。
使用多托槽矫治器进行固定正畸治疗会显著增加菌斑堆积，导致牙龈组织发生显著炎症变化，而无论年龄和性别，牙周袋的临床探诊深度均无显著变化。
