Abstract
Dehidrasyon ve rehidrasyon düzeyinin diş rengi üzerindeki etkisinin farklı renk ölçüm teknikleri ile kantitatif olarak değerlendirilmesi Amaç: Diş rengi seçimi, dehidrasyon ve rehidrasyonla ilgili değişiklikler nedeniyle restoratif diş hekimliğinde önemli bir klinik zorluktur. Bu klinik çalışma, farklı diş fotoğrafçılığı teknikleri kullanılarak farklı diş dehidrasyon ve rehidrasyon seviyeleri arasındaki renk değişimlerini nicel olarak izlemeyi amaçlamıştır. Gereçler ve Yöntem: Üst sağ orta kesici dişin renk değerlendirmeleri kontrol metodu olarak hibrit tip klinik spektrofotometre (RayPlicker; RP), dental fotoğraf kiti (DP) ve mobil dental fotoğraf kiti (MDP) kullanılarak yapıldı. Çapraz polarizasyon filtresi (CP) ve beyaz denge kartı (WB) da DP ve MDP ile kombinasyon halinde kullanıldı. Bu nedenle, sekiz farklı fotoğraf tekniğinin (DP, DP-WB, DP-CP, DP-WB-CP, MDP, MDP-WB, MDP-CP ve MDP-WB-CP) etkinliği araştırıldı. Dehidrasyon (başlangıçta, 1, 2, 3, 5 ve 15. dakikalarda) ve rehidrasyon (30, 60. dakikalarda ve 24. saatte) sırasındaki renk ölçümleri tüm tekniklerle gerçekleştirildi. Renk değişimleri (∆E00*), sonuçların başlangıç değerleriyle karşılaştırılması ile CIEDE2000 formülüne göre hesaplandı. Bulgular: Dehidrasyon sırasındaki RP değerlerine göre, 3. dakikaya kadar olan renk değişimleri algılanamaz düzeyde (∆E<0,8) ve 5. dakikaya göre anlamlı düzeyde düşük bulunmuştur (p<0,001). 5. dakikadaki değişimler algılanabilir aynı zamanda klinik olarak kabul edilebilir düzeyde iken, 15. dakikadaki değerler klinik olarak kabul edilebilir bulunmamıştır (∆E≥1,8). Rehidrasyon sırasındaki RP değerlerine bakıldığında, renk değişimleri algılanabilir düzeyde ve 30. ve 60. dakikalarda 24. saattekilere göre anlamlı şekilde daha yüksek bulunmuştur (p<0,001). Dişlerin %70'inin renk değişimleri 24. saatte 0,8'in altında bulunmuştur. DP/ CP, DP/ WB/ CP, MDP/ CP ve MDP/ WB/ CP teknikleri ile yapılan değerlendirmeler ile RP arasında pozitif yönde çok yüksek korelasyon tespit edilmiştir (her değerlendirme yöntemi için p<0,001). Sonuç: Dişlerde dehidrasyona bağlı oluşan renk değişimi 3. dakikaya kadar algılanamaz düzeyde olup 5. dakikada algılanabilir düzeye ulaşmıştır. 15 dakikalık dehidrasyondan sonra ise klinik olarak kabul edilemez hale gelmiştir. 15 dakikalık dehidrasyondan sonra, 24 saatlik rehidrasyon süresi sonrası bile doğal diş rengi tamamen eski rengine geri dönmeyebilmektedir. CP filtreleri, diş rengi değerlendirmesi için diş fotoğrafçılığı veya mobil diş fotoğrafçılığı cihazları kullanırken temel araçlar olarak kabul edilmiştir.
Quantitative evaluation of the effect of dehydration and rehydration level on tooth color using different color measurement techniques Objective: Dental color selection is an important clinical challenge in restorative dentistry due to the alterations related to dehydration and rehydration. This clinical study aimed to quantitatively monitor the color changes between different levels of tooth dehydration and rehydration using different dental photography techniques. Materials and Methods: Color assessments of the right central incisor were performed using a hybrid-type clinical spectrophotometer (RayPlicker; RP) as control, a dental photography kit (DP), and a mobile dental photography kit (MDP). Cross-polarization filter (CP) and white balance card (WB) were also used in combinations with DP and MDP. Therefore, the effectiveness of eight different photography techniques (DP, DP-WB, DP-CP, DP-WB-CP, MDP, MDP-WB, MDP-CP, and MDP-WB-CP) were investigated. The color measurements during dehydration (at initial, 1, 2, 3, 5, and 15 min) and rehydration (at 30, 60 min, and 24 h) were performed with all techniques. Color changes (∆E00*) were calculated according to the CIEDE2000 formula by comparing the outcomes with the initial values. Results: Regarding the dehydration values by RP, the color changes until the 3rd min were imperceptible (∆E<0,8) and significantly lower than the 5th min (p<0,001). The changes were perceptible but acceptable at the 5th min, while it was not even acceptable (∆E≥1,8) at the 15th min. Regarding the rehydration values by RP, the color changes were perceptible and significantly higher at the 30th and 60th min than at the 24th h (p<0,001). The color changes for 70% of the teeth were below 0,8 at the 24th h. Very high agreements were observed between the assessments by DP/ CP, DP/ WB/ CP, MDP/ CP, and MDP/ WB/ CP techniques, and the RP (p<0,001 for each assessment method). Conclusion: The clinical color change was considered imperceptible until 3 min of dehydration. However, it became perceptible after 5 min of dehydration and not clinically acceptable after 15 min. Following 15 min of dehydration, the natural tooth color may not be completely reversed even after rehydrating for 24 h. CP filters were considered essential tools when using dental photography or mobile dental photography devices for dental color assessment.
