Abstract
Amaç: Üç farklı reçetesiz (OTC) beyazlatma kalemi ile bir ev tipi beyazlatma ürününün kısa dönem beyazlatma etkinliğini, çekilmiş insan dişlerinde spektrofotometrik renk analizi ile değerlendirmek ve karşılaştırmaktır.
Gereç ve Yöntem: Altmış maksiller kesici diş rastgele beş gruba ayrıldı (n=12): üç OTC beyazlatma kalemi (iSmile, SDI Pola Luminate, CleverCool), bir ev tipi beyazlatma jeli (SDI Polanight) ve bir kontrol grubu. Beyazlatıcı ajanlar üretici talimatlarına göre 7 gün boyunca uygulandı. Renk ölçümleri başlangıçta (T0), 7. gün sonunda (T7) ve 14. günde (T14) spektrofotometre kullanılarak yapıldı. Renk değişimi (ΔE), CIELab formülü kullanılarak hesaplandı. Veriler tek yönlü ANOVA ve Tukey HSD testleri ile analiz edildi (p <0.05).
Bulgular: Tüm beyazlatma grupları, kontrol grubuna kıyasla anlamlı derecede daha yüksek ΔE değerleri gösterdi (p <0.001). iSmile kalemi hem T7’de hem de T14’te en yüksek renk değişimini sağladı. SDI Polanight benzer ancak biraz daha düşük etkinlik gösterdi. Pola Luminate ve CleverCool orta düzeyde beyazlatma etkisi sağladı ve aralarında anlamlı bir fark bulunmadı.
Sonuç: OTC beyazlatma kalemleri kısa dönemde gözle görülür renk iyileşmesi sağlayabilir. Ancak etkinlikleri ürün formülasyonuna göre değişmektedir. Daha yüksek peroksit konsantrasyonu daha güçlü beyazlatma etkisi ile ilişkilidir.

Abstract
Objective: This study aimed to assess and compare the short-term whitening performance of three over-the-counter (OTC) whitening pens and one home bleaching agent on extracted human teeth using spectrophotometric color evaluation.
Materials and Methods: Sixty maxillary incisors were randomly distributed into five groups (n = 12 each): three OTC whitening pens (iSmile, SDI Pola Luminate, CleverCool), one home bleaching gel (SDI Polanight), and a control group. Whitening protocols were applied according to manufacturers’ directions for seven consecutive days. Tooth color was recorded at baseline (T0), after 7 days of treatment (T7), and at day 14 (T14) using a spectrophotometer. Color change (ΔE) was calculated through the CIELab system. Statistical analysis was performed with one-way ANOVA and Tukey’s post-hoc tests (α = 0.05).
Results: All experimental groups presented significantly greater ΔE values compared with the control (p < 0.001). The iSmile pen produced the most noticeable change at both T7 and T14. SDI Polanight achieved similar but slightly lower whitening, while Pola Luminate and CleverCool provided moderate improvements with no significant difference between them.
Conclusion: OTC whitening pens are capable of delivering visible short-term whitening effects, although their effectiveness varies across products. A higher peroxide concentration was associated with a more pronounced bleaching outcome.
