简要总结
Background: Various treatment modalities are available to improve esthetics of fluorosed teeth based on its severity.
Aim: evaluate the clinical performance of different minimal invasive treatment protocols on mild to moderate fluorosed teeth.
Materials and Methods: Participants were randomly allocated in eight treatment protocols with twenty teeth (n=20) included in each protocol. (P1) Opalescence boost PF 40%. (P2) Opalustre. (P3) MI-Paste Plus. In (P4) teeth were treated with Opalustre + Opalescence boost PF 40%. In (P5) Opalescence boost PF 40% + MI-Paste Plus, while in (P6) Opalustre +MI-Paste Plus. Whereas (P7) Opalustre + Opalescence boost PF 40% + MI-Paste Plus. (P8) control. All teeth were evaluated for color change (∆E) immediately after treatment (T1), after 14 days (T2), after 3 months (T3) and after 6 months (T4).
Statistical analysis: Two-way ANOVA was applied to test the interaction between different variables. ANOVA repeated measures were followed by Duncan multiple range tests (DMRTs) to compare between groups.
详细描述
This study was conducted for clinical evaluation of the quality of different minimal-invasive treatment modalities and combination treatments in esthetics improvement of mild to moderate fluorosed teeth using two different evaluation methods.
Materials and Methods:
Materials used in this study were Opalustre™ (microabrasion paste of 6.6% hydrochloric acid and Silicon Carbide), Opalescence™ Boost™ PF 40% (in-office bleaching of 40% hydrogen peroxide) and MI-Paste Plus® (topical remineralizing tooth crème of casein phosphopeptide amorphous calcium fluoride phosphate).
One hundred and sixty fluorosed teeth were included in this study. Prior to the interventions, tooth color coordinates were clinically recorded by VITA Easyshade V based on CIE Lab color system as baseline records. After that teeth were randomly allocated in eight treatment protocols with twenty teeth (n=20) included in each protocol. Protocol one (P1) Opalescence™ boost™ PF 40%. Protocol two (P2) Opalustre™. Protocol three (P3) MI-Paste Plus®. In protocol four (P4) teeth were treated with Opalustre™ followed by Opalescence™ boost™ PF 40%. In protocol five (P5) Opalescence™ boost™ PF 40% was applied followed by MI-Paste Plus®, while in protocol six (P6) Opalustre™ was applied followed by MI-Paste Plus®. Whereas protocol seven (P7) teeth were treated with Opalustre™ followed by Opalescence™ boost™ PF 40% and lastly MI-Paste Plus®. Protocol eight (P8) control.
All teeth were evaluated immediately after treatment (T1), after 14 days (T2), after 3 months (T3) and after 6 months (T4). Color change was calculated from the formula ∆E=√((∆〖L)〗^2+(∆〖a)〗^2+〖(∆b)〗^2 ) , where ∆L, ∆a and ∆b were the difference between readings mean values at different evaluating times from the baseline readings. Photographs were taken; immediately after application (T1), after 14 days (T2), after 3 months (T3) and after 6 months (T4).

盲法说明
Masking was ensured as the baseline and follow-ups data were stored on a computer with a unique ID and the investigators were not disclosed about the participants' treatment protocol. Blinding of the participants was guaranteed as they didn't know each other, or the treatments received in other protocols

结局指标
主要结局
Color change (∆E)
时间窗: Six Months
The color measurement was carried out 3 consecutive times with the same evaluator. At each time the obtained values were converted to the corresponding L, a and b values provided by the manufacturer and the mean of three measurements was taken. Color change was calculated from the formula ∆E=√((∆〖L)〗\^2+(∆〖a)〗\^2+〖(∆b)〗\^2 ) ,
