The objectives of this study were to evaluate the effects of a flash-free (FF) System on (1) the amount of plaque accumulation around the braces on buccal surfaces of the teeth, (2) the time required for the placement of brackets, including the clean-up of the flash, (3) the amount of adhesive left on the tooth after debonding, and (4) time required for adhesive remnant clean-up.
Thirty-six patients (aged 19.96 ± 5.74 years) were randomly distributed to receive adhesive precoat (APC)-FF and APC-Plus ceramic brackets on the maxillary right or left anterior 6 teeth. Bonding and debonding time were measured per segment in milliseconds. A plaque revealer agent was applied to discolor the dental plaque, and a modified plaque accumulation index was used to evaluate the amount of plaque at 2 different time points. An adhesive residue index was used after the debonding.
The mean bonding times were 138.87 seconds (8332.47 milliseconds) and 77.82 seconds (4669.31 milliseconds) for APC-Plus and APC-FF, respectively. The difference was statistically significant (P ≤0.001). The difference between the mean debonding times was not statistically significant. A significant difference was found between the adhesive residue index scores of the 2 systems (P ≤0.001). There was no statistically significant difference between plaque accumulation scores at first- and second-time points for both adhesive systems. APC-Plus score (0.94 ± 0.98) was higher than the APC-FF score (0.50 ± 0.91) on the incisal side at the second time point (P ≤0.05).
FF adhesives can be a good alternative to reduce chair time in bonding appointments.
本研究的目的是评估（1）无闪（FF）系统对托槽周围颊面菌斑积累量的影响；（2）放置托槽所需的时间，包括清除闪光；（3）脱落后牙齿上残留的粘合剂量；（4）去除残留胶所需的时间。
将 36 名（年龄 19.96±5.74 岁）患者随机分配到上颌右侧或左侧前 6 颗牙齿上使用预涂层（APC）-FF 和 APC-Plus 陶瓷托槽。以毫秒为单位测量每个节段的粘接和脱粘时间。应用菌斑显色剂使牙菌斑变色，并用改良的菌斑积聚指数在 2 个不同时间点评估菌斑量。脱落后使用粘合残余指数。
APC-Plus 和 APC-FF 的平均粘接时间分别为 138.87 秒（8332.47 毫秒）和 77.82 秒（4669.31 毫秒）。差异具有统计学意义（P≤0.001）。平均脱粘时间的差异无统计学意义。两种系统的粘合残余指数得分存在显著差异（P≤0.001）。两种粘合系统第一次和第二次的菌斑积聚评分无统计学差异。第二次在切端侧，APC-Plus 评分（0.94±0.98）高于 APC-FF 评分（0.50±0.91）（P≤0.05）。
FF 粘合剂可作为减少粘接预约椅旁时间的替代物。
