Effectiveness of and tooth sensitivity with at-home bleaching in smokers

Evaluation of the Efficacy and Color Stability of Two Different At‐Home Bleaching Systems on Teeth of Different Shades: A Randomized Controlled Clinical Trial

“…In the rest period, the teeth may have enough time for rehydration . In previous studies, no rebound in color values was reported 1–3 weeks after bleaching with at‐home systems …”

“…5,24 In previous studies, no rebound in color values was reported 1-3 weeks after bleaching with at-home systems. 25,26 There was statistical rebound in the color values of 10% CP/PF for all shades after 6 months follow-up; however, this color difference was lower than 3.5, which showed that it was clinically acceptable. Different results were obtained from different trials in literature.…”

At-home vs In-office Bleaching: A Systematic Review and Meta-analysis

“…It affects between 37% and 90% of the patients undergoing at-home bleaching 6,9,[12][13][14][15][16][17] and between 16.7% and 100% of the patients using in-office bleaching. 13,[18][19][20] Although tooth sensitivity of at-home bleaching is reported to be mild, 12,13,21 the intensity of tooth sensitivity after in-office bleaching is usually moderate 7,[22][23][24] and in some cases so severe that patients eventually abandon the procedure. 25 Some authors speculate that such an adverse effect may be due to the release of inflammatory mediators such as cyclooxygenase and lipoxygenases on the dental pulp.…”

Efficacy and Colour Stability of Two Different at-Home Bleaching Systems: One-year Randomized Controlled Clinical Trial

“…5,24 Benzer şekilde, diğer araştırmalarda da ev tipi beyazlatma sistemleri ile beyazlatma uygulamasından sonraki 1-3 hafta boyunca renk değerlerinde istatistiksel olarak anlamlı bir geri dönüş saptanmamıştır. 4,25 Tüm renk tonları için %10 KP/PF grubunda 6 aylık ve 1 yıllık izlem döneminden sonra istatistiksel olarak anlamlı geri dönüş gözlenmiştir. Literatürde, farklı araştırmalarda farklı sonuçlar elde edilmiştir.…”
