Abstract

Background: The aim of this in vitro study is to investigate the effectiveness of toothbrushing applied with different toothpastes for removing the discoloration of 3D-printed laminate veneer restorations. Methods: Two different 3D printing resins (Alias Temporary 3D Printing Resin-Dokuz Kimya and VarseoSmile Crown Plus-Bego) were tested. A 3D-printer (Varseo XS-Bego) was used to produce a total of 80 laminate veneer restorations, 40 of each resin type. After the baseline color measurement by spectrophotometer (Vita Easyshade Advance 5.0-Vita Zahnfabrik), the specimens were immersed in distiled water and coffee (Nescafe-Nestle) for 15 days and the color measurement was repeated. Then, the specimens were subjected to toothbrushing simulation for 3 minutes twice a day for 15 days via an electric toothbrush (Vitality-Oral B) with different toothpastes as Colgate Sensation White-Palmolive, Ipana Pro-Expert-Ipana and Bioniq-Dr. Wolff. The color measurement was repetaed and the color changes after discoloration (ΔE1) and toothbrushing simulation (ΔE2) were calculated. Results: The differences between ΔE1 values of all resin groups were significant (p˂0.05). After toothbrushing simulation, the VarseoSmile Crown Plus resins stored in coffee showed significant color restitution (ΔE2bioniq=11.70, ΔE2colgate=11.79, ΔE2ipana=11.79), but Alias Temporary 3D printing resin showed significant color restitution (ΔE2=18.69) only via Ipana Pro-expert toothpaste (p<0.05). Conclusion: The beverages such as coffee seems to negatively affect the color of the 3D printing resins. The regular toothbrushing and the choice of a proper toothpaste seems to be the noteworthy points to obtain the best outcomes for color restitution in 3D-printed restorations. Keywords: color restitution, discoloration, laminate restoration, 3D printing resins, toothbrushing

Özet

Amaç: Bu in vitro çalışmanın amacı, 3B baskılı lamina veneer restorasyonların renklenmesini gidermek için farklı diş macunları ile uygulanan diş fırçalamanın etkinliğini araştırmaktır. Gereç ve Yöntemler: İki farklı 3B baskı reçinesi (Alias Temporary 3D Printing Resin-Dokuz Kimya ve VarseoSmile Crown Plus-Bego) test edilmiştir. Her bir reçine türünden 40 adet olmak üzere toplam 80 lamina veneer restorasyon üretmek için bir 3B yazıcı (Varseo XS-Bego) kullanılmıştır. Spektrofotometre (Vita Easyshade Advance 5.0-Vita Zahnfabrik) ile başlangıç renk ölçümünden sonra, numuneler 15 gün boyunca distile su ve kahvede (Nescafe-Nestle) bekletilmiş ve renk ölçümü tekrarlanmıştır. Ardından, örnekler 15 gün boyunca günde iki kez 3 dakika süreyle elektrikli diş fırçası ve (Vitality-Oral B) Colgate Sensation White-Palmolive, Ipana Pro-Expert-Ipana ve Bioniq-Dr. Wolff gibi farklı diş macunlarıyla diş fırçalama simülasyonuna tabi tutulmuştur. Renk ölçümü tekrarlanmış ve renk değişimi (ΔE1) ve diş fırçalama simülasyonu (ΔE2) sonrası renk değişimleri hesaplanmıştır. Bulgular: Tüm reçine gruplarının ΔE1 değerleri arasındaki farklar anlamlıydı (p˂0.05). Diş fırçalama simülasyonundan sonra, kahvede bekletilmiş VarseoSmile Crown Plus reçinesi anlamlı renk değişimi göstermiştir (ΔE2bioniq=11.70, ΔE2colgate=11.79, ΔE2ipana=11.79), ancak Alias Temporary 3D baskı reçinesinin sadece Ipana Pro-expert diş macunu ile fırçalanan grubu anlamlı renk değişimi (ΔE2=18.69) göstermiştir (p<0.05). Sonuç: Kahve gibi renklendirici içeceklerin 3B baskı reçinelerinin rengini olumsuz etkilediği görülmektedir. Düzenli diş fırçalama ve uygun bir diş macunu seçimi, 3B baskı yöntemi ile üretilen restorasyonların renklenmesini gidermede en iyi sonuçları elde etmek için dikkate değer noktalar gibi görünmektedir. Anahtar Kelimeler: renk restorasyonu, renklenme, lamina restorasyon, 3B baskı reçineleri, diş fırçalama
