To investigate teeth's antibiotic-induced color differences after bleaching using two different techniques.
One hundred twenty extracted maxillar human incisors were examined. The specimens were randomly divided into six groups, each receiving one of six antibiotic paste fillings: (1) triple antibiotic paste (TAP) with minocycline, (2) double antibiotic paste (DAP), (3) TAP with amoxicillin, (4) TAP with cefaclor, (5) TAP with doxycycline, and (6) no filling (control group). Spectrophotometric measurements were obtained at baseline and then during the first, second, and third weeks after paste placement. The specimens discolored by antibiotics pastes were randomly divided into two subgroups: (1) internal bleaching with hydrogen peroxide (HO and (2) internal bleaching with HO plus Nd-YAG laser irradiation. The ∆E value was calculated and analyzed using a two-way analysis of variance and post-hoc Tukey's test (α = 0.05).
The ∆E for all groups showed color differences exceeding the perceptibility threshold (∆E ˃ 3.7) at all time points except in the control and DAP groups. Minocycline-induced TAP showed the most severe coronal discoloration (32.42). When the ∆E was examined, thermo/photo bleaching (22.01 ± 8.23) caused more bleaching than walking bleaching (19.73 ± 5.73) at every time point (P = 0.19). No group returned to the original color after bleaching (P < 0.05).
Except for DAP, all antibiotic pastes caused discoloration. Internal bleaching with Nd-YAG laser can be useful for bleaching/removing this discoloration.
For clinically successful final appearances, understanding the effects of bleaching procedures on antibiotic paste discoloration is important.
研究两种不同技术漂白后牙齿的抗生素诱导的颜色差异。
检查了 120 颗上颌人切牙。将标本随机分为六组，每组接受一种抗生素糊剂填充：（1）含米诺环素的三联抗生素糊剂（TAP），（2）双抗生素糊剂（DAP），（3）含阿莫西林的 TAP，（4）含头孢克洛的 TAP，（5）含多西环素的 TAP，和（6）无填充（对照组）。在基线时以及在糊剂放置后的第一、第二和第三周进行分光光度测量。用抗生素糊剂染色的标本随机分为两组：（1）用双氧水（HO）进行内部漂白，（2）用 HO 加 Nd-YAG 激光照射进行内部漂白。使用双向方差分析和事后 Tukey 检验（α = 0.05）计算和分析 ∆E 值。
除对照组和 DAP 组外，所有组在所有时间点的 ∆E 均显示出超过可感知阈值的颜色差异（∆E > 3.7）。米诺环素诱导的 TAP 显示出最严重的冠部变色（32.42）。当检查 ∆E 时，热/光漂白（22.01 ± 8.23）在每个时间点都比步行漂白（19.73 ± 5.73）引起更多的漂白（P = 0.19）。没有一个组在漂白后恢复到原始颜色（P < 0.05）。
除 DAP 外，所有抗生素糊剂都导致变色。Nd-YAG 激光内漂白对于漂白/去除这种变色可能是有用的。
为了获得临床上成功的最终外观，了解漂白程序对抗生素糊剂变色的影响很重要。
