Aim To compare the periodontal status in relation to the lower anteriors of patients between labial and lingual orthodontic therapy. Materials and methods The study includes a total of 20 patients in the age group of 20-30 years. All the included patients were selected with limited lower anterior crowding within 0-8 mm. The subjects were randomly divided into two groups: labial (n=10) and lingual (n=10) fixed orthodontic therapy. The periodontal status was evaluated using three indices, plaque index, calculus index, and gingival index, at two different treatment intervals - the first month and the third month - of orthodontic treatment. Results The values of all the three indices at both time intervals were tabulated. There was no statistical significance when compared to the values in the first month. In the third month, all three indices were statistically significant for both labial and lingual therapy (p<0.001). The lingual appliance had more plaque and calculus accumulation. Conclusion Therefore, the study proves that the lingual surface of patients undergoing lingual orthodontic treatment exhibits more plaque and calculus deposition, thereby the weakening of the periodontal status.
目的 比较唇侧和舌侧正畸治疗患者下颌前牙区的牙周状况。材料与方法 本研究共纳入20例年龄在20至30岁之间的患者。所有纳入患者均为下颌前牙拥挤度在0至8毫米之间的有限拥挤病例。将受试者随机分为两组：唇侧固定正畸治疗组（n = 10）和舌侧固定正畸治疗组（n = 10）。在正畸治疗的两个不同时间间隔——第一个月和第三个月——使用菌斑指数、牙石指数和牙龈指数这三个指标评估牙周状况。结果 将两个时间间隔的所有三个指标的值制成表格。与第一个月的值相比，无统计学意义。在第三个月，唇侧和舌侧治疗的所有三个指标均具有统计学意义（p < 0.001）。舌侧矫治器有更多的菌斑和牙石堆积。结论 因此，本研究证明接受舌侧正畸治疗的患者舌侧表面有更多的菌斑和牙石沉积，从而导致牙周状况变差。
