Abstract
Objective: This study aims to evaluate the periodontal health of adult orthodontic patients using three types of brackets: conventional metal, conventional ceramic, and metal self-ligating brackets. It further examines the geometry and surface roughness of each bracket type, correlating these factors with periodontal health outcomes. Methods: A cross-sectional analysis was conducted with 150 adult orthodontic patients divided into three groups based on the type of brackets used. Clinical parameters, including probing depth (PD), clinical attachment level (CAL), gingival index(GI), and plaque index (PI), were measured. The geometry and surface roughness of the brackets were analyzed using a profilometer. Statistical analysis was performed to compare periodontal health among the groups. Results: The results indicated significant differences in PD, CAL, GI, and PI among the three groups. Metal self-ligating brackets exhibited the lowest PD and GI scores, while conventional ceramic brackets showed the highest scores. Additionally, metal self-ligating brackets had superior surface roughness characteristics. Conclusion: The type of orthodontic bracket used, along with its geometry and surface roughness, can significantly affect periodontal health in adult patients. Metal self-ligating brackets may provide a favorable periodontal outcome compared to conventional brackets.
