“…However, the HP mouthwash concentration was relatively low at 1.5%. Tanthanuch et al found that the acidity of the 1.5% HP could promote greater roughness in the resin composite surface, which may result in increased mechanical retention to the RMCs surface and promote greater repair SBS as a result of this study [ 46 ].…”

“…This study revealed the difference between the PVP-I and HP based on the SBS of the repaired RMCs. Tanthanuch et al reported that PVP-I and HP affect the roughness and color change of the composite resins due to their ability to diffuse through the polymer network [ 46 ]. Therefore, the PVP-I and HP mouthwashes may be able to diffuse through the polymer matrix of the RMCs and then affect the SBS.…”

Using anti-COVID-19 mouthwashes has become necessary to reduce acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmissions. Resin-matrix ceramic (RMCs) materials that are exposed to mouthwashes may affect the bonding of repaired materials. This research was performed to assess the effects of anti-COVID-19 mouthwashes on the shear bond strengths (SBS) of RMCs repaired with resin composites. A total of 189 rectangular specimens of two different RMCs (Vita Enamic (VE) and Shofu Block HC (ShB)) were thermocycled and randomly divided into nine subgroups according to different mouthwashes (distilled water (DW), 0.2% povidone–iodine (PVP-I), and 1.5% hydrogen peroxide (HP)) and surface treatment protocols (no surface treatment, hydrofluoric acid etching (HF), and sandblasting (SB)). A repair protocol for RMCs was performed (using universal adhesives and resin composites), and the specimens were assessed using an SBS test. The failure mode was examined using a stereomicroscope. The SBS data were evaluated using a three-way ANOVA and a Tukey post hoc test. The SBS were significantly affected by the RMCs, mouthwashes, and surface treatment protocols. Both surface treatment protocols (HF and SB) for both RMCs, whether immersed in anti-COVID-19 mouthwash or not, improved the SBS. For the VE immersed in HP and PVP-I, the HF surface treatment had the highest SBS. For the ShB immersed in HP and PVP-I, the SB surface treatment had the highest SBS.

“…Previous research found that NCR showed less VHN involvement than hybrids when exposed to acidic liquids (pH ≤ 3.2) after 7 days [24] and 15 days [23]. Another study found less VHN involvement in Z350 XT resins, especially when exposed to CHX at 0.12 (pH = 6.07) compared to other classifications of resin fillers and mouthrinses with a lower pH (<4.1) after 7 days [25].…”

“…The findings of this study are consistent with those mentioned above. This could be explained in that a greater volume of the filler and a smaller particle size of composite resins based on nanohybrid compounds compared to hybrid compounds provide greater efficiency in the response to degradation of the polymer matrix, especially with low pH values [23,25,28]. Likewise, an acidic environment caused by interaction with alcoholbased mouthwashes can hydrolyze ester radicals into monomer-like compounds.…”

Introduction. Daily use of different mouthrinses at home or in the dental office can alter the properties of resin hardness. The present study aimed to compare Vickers microhardness (VHN) in vitro of nanohybrid composite resins (NCRs) immersed in mouthrinses. Materials and Methods. In total, 120 discs (10 ⨯ 2 mm) were prepared from three NCR shade A2 (n = 40/group) with FiltekTM Z350 XT (Z350XT), Tetric EvoCeram (TEC), and Polofil NHT (PNHT). The specimens were incubated in artificial saliva (37°C ⨯ 24 hr). Specimens were distributed into four mouthrinses (n = 10/group) of artificial saliva (control), chlorhexidine (CHX 0.12%, pH 5.6), cetylpyridine chloride (CPC 0.075%, pH 5.84), and CHX 0.12% + CPC 0.05% (pH 6.2) (2 times/day, 2’ ⨯ 12 hr). The VHN (300 gf/10”) was measured after 24 hr, 14, and 21 days. Data were analyzed by three-way analysis of variance, followed by post hoc Tukey analysis at 0.05 level of significance. Results. The results revealed a global effect of the interaction of the mouthrinses ⨯ time between NRC evaluated ( P = 0.001 ). Baseline VHN in PNHT and Z350XT was higher than TEC. Within each group of NCR, VHN of CHX + CPC > other mouthrinses (PNHT/14 days; Z350XT/21 days), and >CPC (Z350XT/14 days). In mouthrinses-intragroups, VHN of PNHT and Z350XT decreased at 14 days (CHX, CPC) and was maintained over time in NCR (CHX + CPC). VHN-TEC was similar among groups. Conclusion. Microhardness showed differences due to the interaction of the type of NCR, the composition of the mouthrinses, and time. VHN decreased after 14 days and was more affected in composite resins with lower filler content and in mouthrinses with a lower pH.

Bu çalışmanın amacı, anterior kompozit rezinlerin 1 yıllık yaşlandırma ve kola solüsyonuna maruziyet sonrası farklı periyotlarda yüzey pürüzlülüğünün ve sertliğinin değerlendirilmesidir. Çalışma kapsamında, 5 farklı kompozit (Optishade, Clearfil Majesty ES-2, Omnichroma, G'aenial A'chord ve G'aenial Anterior) ve bir kompozitin 2 farklı rengi (Optishade LT ve Optishade MD) değerlendirilmiştir. 24 saat distile suda bekledikten sonra örneklerin başlangıç (T0), 1 yıllık yaşlandırmaya denk gelicek şekilde termalsiklus sonrası (T1), kola solüsyonunda 7 gün (T2), 15 gün (T3) ve 30 gün (T4) bekletme sonrasında yüzey pürüzlülüğü ve sertliği ölçümleri yapılmıştır. Elde edilen verilerin istatistiksel analizi tek yönlü varyans analizi (ANOVA) ve Tukey çoklu karşılaştırmaları kullanılarak gerçekleştirildi (p= 0.05). Elde edilen veriler doğrultusunda yaşlandırma işlemlerinin de düşük pH’a sahip kola solüsyonuna maruziyetin de anterior kompozit rezin restoratif materyallerin yüzey pürüzlülüğü ve sertliği üzerinde etkili olduğu tespit edilmiştir. Yüzey sertliği sonuçları değerlendirildiğinde T0, T1, T2, T3 ve T4 ’de yapılan ölçümlerde kompozit rezin restoratif materyaller arasında istatistiksel olarak anlamlı farklılık olduğu görülmüştür (p
