Abstract

Objectives: To compare the intensity, location, and short-term impact of the periodontal discomfort/pain, as well as the related functional parameters of bite force and masticatory efficiency, between self-ligating and conventional orthodontic appliances.

Materials and methods: In 20 patients referred for orthodontic treatment, samples were collected from the gingival sulcus to evaluate the level of substance P using enzyme-linked immunosorbent assay. Orthodontic devices were randomly bonded, with self-ligating appliances on one side and conventional brackets on the contralateral side. Pain threshold (PT), maximal bite force (MBF), and masticatory efficiency (ME) were assessed using standard validated techniques at the beginning of the treatment and 24 hours post-orthodontic activation with an 0.016-inch nickel-titanium wire.

Results: There were no significant differences (P > .05) in the substance P levels, PT, MBF, and ME between the self-ligating and conventional orthodontic appliances.

Conclusions: There was no difference between conventional and self-ligating appliances in the parameters of pain: substance P and pressure. Functional aspects, such as pain, discomfort, and masticatory efficiency, should not be considered when making a therapeutic decision regarding the use of self-ligating vs conventional orthodontic appliances.

一项临床研究:与I类患者的传统正畸矫治器相比，自结扎托槽不能减轻不适或疼痛。

目的:比较自结扎矫治器与常规矫治器牙周不适/疼痛的强度、部位、短期影响及咬合力、咀嚼效率等相关功能参数。材料与方法:选取20例正畸治疗患者，取龈沟标本，采用酶联免疫吸附法测定P物质水平。正畸装置随机粘接，一侧使用自结扎器，对侧使用常规托槽。疼痛阈值(PT)、最大咬合力(MBF)和咀嚼效率(ME)在治疗开始和正畸后24小时用0.016英寸镍钛丝激活时使用标准验证技术进行评估。结果:自结扎矫治器与常规矫治器在P物质水平、PT、MBF、ME等指标上差异均无统计学意义(P > 0.05)。结论:常规和自结扎器在疼痛参数P物质和压力方面无差异。功能方面，如疼痛、不适和咀嚼效率，在决定使用自结扎与传统正畸矫治器时不应考虑。
