The effect of professional prophylaxis on the periodontium was studied in 14 adolescent orthodontic patients while under active treatment using a split-mouth experimental design. A full-banded appliance was used on all of the patients. The following variables were examined: plaque registration, gingival index, gingival migration, and width of the attached gingiva. Professional rubber-cup prophylaxis was performed on the test side of all patients together with reinforced oral hygiene instruction on a monthly basis. Measurements for the plaque registration, gingival index, gingival migration, and the width of the attached gingiva were recorded at the initial visit (baseline records), the 6-month evaluation, and the 10-month evaluation. Monthly registrations were completed for the plaque deposits and gingival inflammation at each of the 11 visits. All measurements were taken at the midfacial surface of the selected teeth. Four conclusions can be drawn from the findings of this study: the presence of an orthodontic appliance did not result in an increase of plaque accumulation or gingival inflammation for the full-banded orthodontic patient; monthly oral hygiene instruction was effective in significantly reducing the amount of visible plaque and gingival inflammation; monthly rubber-cup prophylaxis had a significant effect in reducing the gingival enlargement routinely associated with a fixed orthodontic appliance; and the width of attached gingiva showed no significant change throughout the course of the study.
采用双盲实验设计，对14名正在接受积极治疗的青少年正畸患者在治疗期间专业预防措施对牙周组织的影响进行了研究。所有患者均使用全带环矫治器。检测了以下变量：菌斑记录、牙龈指数、牙龈移位和附着龈宽度。对所有患者的测试侧进行专业的橡皮杯清洁，并每月加强口腔卫生指导。在初次就诊（基线记录）、6个月评估和10个月评估时记录菌斑记录、牙龈指数、牙龈移位和附着龈宽度的测量值。在11次就诊中的每次就诊时，都要完成对菌斑沉积和牙龈炎症的每月记录。所有测量均在所选牙齿的中面部表面进行。从本研究结果可以得出四个结论：对于全带环正畸患者，正畸矫治器的存在不会导致菌斑积聚或牙龈炎症增加；每月的口腔卫生指导在显著减少可见菌斑量和牙龈炎症方面有效；每月的橡皮杯清洁在减少与固定正畸矫治器常规相关的牙龈增生方面有显著效果；在整个研究过程中，附着龈宽度没有显著变化。
