结局指标
主要结局
Plaque index measurements
时间窗: 12 months (T2) after bonding
Plaque index was scored by a specialized periodontist on the mesiolingual, lingual, and distolingual sides of each tooth at 12 months after bonding based on the following scale: 0 (no plaque), 1 (a film of plaque adhering to the free gingival margin and adjacent area of the tooth), 2 (moderate accumulation of soft deposits within the gingival pocket, or on the tooth and gingival margin which can be seen with the naked eye) and 3 (abundance of soft matter within the gingival pocket and/or on the tooth and gingival margin). All measurements were performed using acrylic stents to ensure reproducible placement of the periodontal probe (PCP 15 UNC, Hu-Friedy, Chicago, IL).
Gingival index measurements
时间窗: 12 months (T2) after bonding
Gingival index was scored by a specialized periodontist on the mesiolingual, lingual, and distolingual sides of each tooth at 12 months after bonding based on the following scale: 0 (absence of inflammation), 1 (mild inflammation), 2 (moderate inflammation) and 3 (severe inflammation). All measurements were performed using acrylic stents to ensure reproducible placement of the periodontal probe (PCP 15 UNC, Hu-Friedy, Chicago, IL).
Calculus index measurements
时间窗: 12 months after bonding
Calculus index was scored by a specialized periodontist on the mesiolingual, lingual, and distolingual sides of each tooth at 12 months after bonding based on the following scale: 0 (no calculus present), 1 (supragingival calculus covering not more than one third of the exposed tooth surface), 2 (supragingival calculus covering more than one third but not more than two thirds of the exposed tooth surface or the presence of individual flecks of subgingival calculus around the cervical portion of the tooth or both) and 3 (supragingival calculus covering more than two thirds of the exposed tooth surface or a continuous heavy band of subgingival calculus around the cervical portion of the tooth or both). All measurements were performed using acrylic stents to ensure reproducible placement of the periodontal probe (PCP 15 UNC, Hu-Friedy, Chicago, IL)
Plaque index measurements
时间窗: at the bonding session
Plaque index was scored by a specialized periodontist on the mesiolingual, lingual, and distolingual sides of each tooth at the bonding session based on the following scale: 0 (no plaque), 1 (a film of plaque adhering to the free gingival margin and adjacent area of the tooth), 2 (moderate accumulation of soft deposits within the gingival pocket, or on the tooth and gingival margin which can be seen with the naked eye) and 3 (abundance of soft matter within the gingival pocket and/or on the tooth and gingival margin). All measurements were performed using acrylic stents to ensure reproducible placement of the periodontal probe (PCP 15 UNC, Hu-Friedy, Chicago, IL).
Plaque index measurements
时间窗: 6 months (T1) after bonding
Plaque index (PI) was scored by a specialized periodontist on the mesiolingual, lingual, and distolingual sides of each tooth at 6 months after bonding based on the following scale: 0 (no plaque), 1 (a film of plaque adhering to the free gingival margin and adjacent area of the tooth), 2 (moderate accumulation of soft deposits within the gingival pocket, or on the tooth and gingival margin which can be seen with the naked eye) and 3 (abundance of soft matter within the gingival pocket and/or on the tooth and gingival margin).
