Bu çalışma, dehidrasyona yol açan çeşitli klinik prosedürlerin doğal dişlerdeki renk değişimi üzerindeki etkilerini incelemektedir. Üst kesici dişlerin CIE L*, a* ve b* renk koordinatları, işlem öncesi ve sonrası 10, 20, 30 ve 1440 (24 saat) dakikalık aralıklarla bir spektrofotometre kullanılarak ölçüldü. Test grupları şu şekildeydi: LED ve halojen dental reflektörler altında 6 ve 15 dakika açık ağız; kontrol grupları karanlık bir ortamda 6 ve 15 dakika süreyle değerlendirildi; maksiller ölçüler kondenzasyon ve ilave tip ölçü materyalleri ile alınmıştır. İki gruplu karşılaştırmalar için Wilcoxon işaretli sıra testleri ve Mann-Whitney U testleri kullanıldı. Analizler, eşleştirilmiş ve bağımsız gruplar için Friedman ve Kruskal-Wallis H testleri ile hesaplandı. Bu testleri Bonferroni posthoc düzeltmeleri izledi. Elde edilen renk değerleri, işlemden 20 dakika sonra dehidrasyona bağlı olarak tüm gruplar için önemli L* değişikliklerini göstermektedir. Renk değişiklikleri (ΔE), algılanabilirlik eşiği (1.2>ΔE) için 30 dakika ve kabul edilebilirlik eşiği (2.7>ΔE) için 20 dakika boyunca önemliydi. Sonuçlar, ağız açılmasını gerektiren diş prosedürlerini taklit etmek için tasarlanmış deneysel protokollerin, doğal dişlerde geçici renk değişimlerine ve renk eşleştirme sırasında başarısızlığa neden olabileceğini göstermektedir.

This study examines the effects of several clinical procedures that lead to dehydration on color change in natural teeth. CIE L*, a*, and b* color coordinates of maxillary incisors were measured using a spectrophotometer before and after the procedure at minute intervals of 10, 20, 30, and 1440 (24 hours). Test groups were as follows: 6 and 15 minutes of the open mouth under LED and halogen dental reflectors; control groups were evaluated in a dark environment for 6 and 15 minutes; maxillary impressions were taken with condensation and additional type impression materials. Wilcoxon signed-rank tests and Mann–Whitney U tests were used for two-group comparisons. The analyses were computed by the Friedman and Kruskal–Wallis H tests for the paired and independent groups. These tests were followed by Bonferroni posthoc corrections. Obtained color values indicate significant L* changes for all groups due to dehydration for 20 minutes after the procedure. Color changes (ΔE) were significant for 30 minutes for the perceptibility (1.2>ΔE) and 20 minutes for the acceptability threshold (2.7>ΔE). Results show that experimental protocols designed to mimic dental procedures that require mouth opening may cause temporary discoloration of natural teeth, which may cause failure during shade matching.
