The objective of this study was to test a new method, a Standardized Way to Assess Grafts (SWAG), to rate alveolar bone graft (ABG) outcomes for patients with cleft lip and palate.
This was a retrospective comparison using the SWAG scale.
This study took place in four cleft palate centers with different treatment protocols.
A total of 160 maxillary occlusal radiographs taken 3 to 18 months post-ABG for sequentially treated patients with cleft lip and palate were assessed using the SWAG scale. Radiographs were scanned, standardized, blinded, and rated by 6 calibrated orthodontists to assess vertical thirds, bony root coverage, and complete bony fill. All radiographs were rated twice, 24 hours apart, by the same raters.
Intra- and interrater reliabilities were assessed.
Intrarater reliability was good to very good (.760; .652-.834), and interrater reliability was moderate to good (.606; .569-.681), comparable to previously published methods.
Rater reliabilities were shown to be comparable to or better than existing methods. The SWAG method was validated for ABG assessments in the mixed and permanent dentitions based on reliabilities in an intercenter outcome comparison.
本研究的目的是测试一种新方法，即标准化移植物评估方法（SWAG），用于评估唇腭裂患者的牙槽骨移植（ABG）效果。
这是一项使用SWAG量表的回顾性比较研究。
本研究在四个采用不同治疗方案的腭裂中心进行。
使用SWAG量表对160例唇腭裂患者在ABG术后3至18个月拍摄的上颌咬合片进行评估，这些患者为序贯治疗。对X光片进行扫描、标准化、设盲，由6名经过校准的正畸医生进行评分，以评估垂直三等份、牙根骨覆盖情况和骨完全填充情况。所有X光片均由相同的评分者在间隔24小时的情况下进行两次评分。
评估了评分者内和评分者间的可靠性。
评分者内可靠性良好至非常好（.760；.652-.834），评分者间可靠性中等至良好（.606；.569-.681），与先前发表的方法相当。
结果表明评分者可靠性与现有方法相当或更好。基于中心间结果比较的可靠性，SWAG方法在混合牙列和恒牙列的ABG评估中得到了验证。
