Objectives

This laboratory study evaluated the influence of the fluorescence intensity of composite resins on additional tooth wear and the presence of restorative material in different dental thirds during the retreatment of direct veneers.

Materials and Methods

The crown dimensions of 60 bovine incisors were reduced to 10 × 8 mm. The teeth were classified according to the fluorescence intensity of the composites: low (LOW) (TPH Spectra), medium (MED) (Opallis), and high (HIGH) (Essentia) groups. The teeth were divided according to the removal methods: conventional (CON) and fluorescence-aided identification technique (FIT). The specimens were scanned (T0), received veneer preparation, and scanned again (T1). After restorations, the composites were removed and the teeth were scanned (T2). Measurement assessments between T1 and T2 were performed to determine additional wear, presence of residual areas, and the average between additional wear and the presence of residual areas. Kruskal Wallis, Mann–Whitney, Friedman, 2-way ANOVA, and post-Tukey tests were performed (α < 0.05).

Results

The comparison of composite resins indicated a smaller area of additional wear and greater residue presence in the HIGH group than the LOW group for both techniques in the cervical third. Regarding removal methods, the FIT produced greater additional wear than the CON method for the LOW and MED groups in the middle and cervical thirds. The incisal third exhibited greater additional wear than the other thirds.

Conclusions

Composite resins with high fluorescence intensity removed using FIT had less tooth wear. The incisal third was the most affected area for direct veneer removal procedures.

Clinical Significance

A FIT has been proposed for composite resin removal; however, the different fluorescence intensities of composite resins can influence tooth wear caused during this procedure.

目的：本实验室研究评估了复合树脂的荧光强度对直接贴面修复过程中额外牙齿磨损和不同牙列中修复材料存在的影响：本实验室研究评估了复合树脂的荧光强度对直接贴面修复过程中额外牙齿磨损和不同牙三分区修复材料存在的影响：将 60 颗牛门牙的牙冠尺寸缩小至 10 × 8 毫米。根据复合材料的荧光强度对牙齿进行分类：低（LOW）组（TPH Spectra）、中（MED）组（Opallis）和高（HIGH）组（Essentia）。牙齿根据去除方法分为：传统（CON）和荧光辅助识别技术（FIT）。对样本进行扫描（T0），接受贴面制备，然后再次扫描（T1）。修复后，去除复合材料并对牙齿进行扫描（T2）。在 T1 和 T2 之间进行测量评估，以确定额外的磨损、是否存在残留区域以及额外磨损和残留区域之间的平均值。进行了 Kruskal Wallis、Mann-Whitney、Friedman、双向方差分析和后图基检验（α 结果：复合树脂的比较结果表明，在宫颈三分之一处，两种技术的高组比低组的额外磨损面积更小，残留物更多。在去除方法方面，低度组和中度组的中三度和颈三度FIT比CON方法产生了更大的额外磨损。切缘三分区的额外磨损大于其他三分区：结论：使用 FIT 去除荧光强度高的复合树脂时，牙齿磨损较少。临床意义：临床意义：FIT 已被推荐用于去除复合树脂；然而，复合树脂的不同荧光强度会影响该过程中造成的牙齿磨损。

Objective

To measure degree of conversion (DC) of a flowable composite, microtensile bond strength (MTBS) to dentine in the snow-plow technique with/without preheating and temperature in the preheated composite.

Materials and Methods

For DC, snow-plow specimens of Filtek Ultimate Flowable (Flow) and Filtek Bulk Fill (Bulk) (3M) were prepared by light-curing composites simultaneously in standardized molds while in control groups light-curing was separate. DC of Flow was measured using micro-Raman spectroscopy. For MTBS, specimens were prepared on dentine of human extracted molars by simultaneous (snow-plow) or separate (control) light-curing. MTBS was measured using a universal testing machine after 24 h and 6 months. Data were analyzed using ANOVA with Tukey's post hoc (α = 0.05).

Results

Increased curing time significantly increased DC in snow-plow from 13.4% ± 11.6% (10 s) to 31.8% ± 4.4% (40 s) albeit significantly lower than controls (p < 0.05). Preheated Bulk improved conversion in snow-plow (44.3% ± 1.7%) and control (50.5% ± 2.6%) (p < 0.05). No significant differences occurred in MTBS between groups (p > 0.05). MTBS values ranged between 66.7 ± 8.4 MPa (snow-plow group_21°C_baseline) and 54.1 ± 15.8 MPa (control_21°C_long-term). Temperature in the preheated Bulk dropped to ~38°C after 30 s.

Conclusions

Snow-plow technique, irrespective of preheating, resulted in lower DC of Flow than separate light-curing of composite increments. Snow-plow, irrespective of preheating, resulted in similar initial and long-term MTBS to dentine.

Clinical Significance

Clinicians with preference for flowable composite liners in Class II restorations should be aware that the snow-plow technique of simultaneous light-curing of flowable and bulk-fill composite increments affects monomer-to-polymer conversion, albeit no effect on immediate, and long-term bonding to dentine was detected. Preheating sculptable bulk-fill composite improves conversion of the flowable liner in the snow-plow technique but has no detectable effect on bond strength to dentine.

目的：测量可流动复合材料的转换度（DC）、雪犁技术中与牙本质的微张力粘接强度（MTBS）、预热/不预热以及预热复合材料的温度：对于直流电，Filtek Ultimate Flowable（Flow）和 Filtek Bulk Fill（Bulk）（3M）的雪犁试样是在标准模具中同时光固化复合材料制备的，而对照组的光固化是分开进行的。流体的直流电用微拉曼光谱法测量。对于 MTBS，在人类拔出的臼齿的牙本质上通过同时光固化（刨雪）或单独光固化（对照组）制备试样。分别在 24 小时和 6 个月后使用万能试验机测量 MTBS。采用方差分析和 Tukey 后验（α = 0.05）对数据进行分析：固化时间的延长明显增加了扫雪机的 DC，从 13.4% ± 11.6% (10 秒) 增加到 31.8% ± 4.4% (40 秒)，尽管明显低于对照组 (p 0.05)。MTBS 值介于 66.7 ± 8.4 兆帕（扫雪机组_21°C_基准）和 54.1 ± 15.8 兆帕（对照组_21°C_长期）之间。预热块体的温度在 30 秒后降至约 38°C：结论：与复合材料增量的单独光固化相比，无论预热与否，扫雪技术都能产生较低的流动直流电。无论预热与否，雪犁技术与牙本质的初始和长期 MTBS 相似：临床意义：在二类修复体中偏爱使用可流动复合材料内衬的临床医生应该注意，同时光固化可流动和块状填充复合材料增量的 "雪犁 "技术会影响单体到聚合物的转化，尽管没有发现这种技术会影响与牙本质的即时和长期粘接。预热可雕刻散装填充复合材料可以提高雪犁技术中流动衬垫的转化率，但对与牙本质的粘接强度没有影响。

Objective

Color Adjustment Potential evaluates the color blending of dental Composite Resins. While Color Adjustment Potential is simple, its clinical relevance is unclear. This research aims to understand it better and to create an index for Composite Resins with meaningful clinical interpretation.

Materials and Methods

Single and double shade composite disks of various diameters and opacities were created to test the indices. Color measurements used a dental colorimeter, avoiding subjective assessments. Color Adjustment Potential analysis of each material revealed insights, leading to the creation of a new Color Blending Threshold, providing a clinically relevant numerical value for Composite Resins.

Results

Color Adjustment Potential's numerical significance was clarified and introduced a new index for clinical applications. Color adaptation of each test shade to all Vita shades was also calculated, useful for single-shade restorations in open and closed cavity types.

Conclusions

The proposed Color Blending Threshold defines the open/closed cavity dimension that can be adequately restored with a single shade of resin composite.

Clinical Significance

Understanding how dental materials adapt to surrounding tooth colors enhances esthetic restorations, simplifies shade matching, and optimizes resin composite production. The proposed Color Blending Threshold is a parameter that directly relates to the clinical significance of a material's true color blending ability. It defines the cavity dimension that can be adequately restored with a single shade of resin composite while ensuring that the resulting color difference falls below a predetermined threshold, meeting the clinical requirements for an esthetic restoration.

目标：颜色调节电位可评估牙科复合树脂的颜色混合度。虽然颜色调节电位很简单，但其临床意义并不明确。本研究旨在更好地了解它，并为复合树脂创建一个具有临床解释意义的指标：材料和方法：制作了不同直径和不透明度的单色和双色复合树脂盘来测试指数。颜色测量使用牙科色度计，避免主观评估。通过对每种材料的颜色调节电位分析，我们发现了新的颜色混合阈值，为复合树脂提供了一个与临床相关的数值：结果：明确了颜色调节电位的数值意义，并为临床应用引入了新的指标。此外，还计算了每个测试色调对所有 Vita 色调的颜色适应性，这对开放式和封闭式牙洞类型的单色调修复非常有用：结论：所提出的颜色混合阈值定义了单一色调树脂复合材料可充分修复的开放/封闭牙洞尺寸：临床意义：了解牙科材料如何适应周围牙齿的颜色可以提高修复的美观度、简化色调匹配并优化树脂复合材料的生产。所提出的颜色混合阈值是一个直接关系到材料真实颜色混合能力临床意义的参数。它定义了可以用单一色调的树脂复合材料进行充分修复的牙洞尺寸，同时确保所产生的色差低于预定的阈值，满足美学修复的临床要求。

Objectives

To investigate the effect of cumulative doses of radiation on the pushout bond strength (BS) of a universal resin cement used in the self-etch (SE) and self-adhesive (SA) modes to the intraradicular dentin.

Materials and Methods

Forty-eight human teeth were distributed into three groups (n = 16) according to the radiation therapy dose (RT): NoRT (no-radiotherapy), 70RT (70 Gy), and 70 + 70RT (70 Gy + 70 Gy). The teeth were redistributed into two subgroups (n = 8), according to the adhesive mode: SE (NoRT-SE, 70RT-SE, and 70 + 70RT-SE) and SA (NoRT-SA, 70RT-SA, and 70 + 70RT-SA). Data were statistically compared after BS test (ANOVA, Tukey's post hoc test, and Fisher's exact test).

Results

In the SA mode, BS was significantly higher in nonirradiated teeth compared with 70RT and 70 + 70RT (p < 0.0001). There were no significant differences between SE and SA modes in nonirradiated teeth (p = 0.14). In the 70RT group, SE mode increased BS compared with SA mode (p < 0.0001). Most specimens had adhesive and mixed failures in SA and SE modes, respectively.

Conclusions

The universal resin cement in the SE mode had greater BS to the irradiated dentin. When teeth were re-irradiated, the universal resin cement had similar performance in terms of BS, regardless of the adhesive approach.

Clinical Significance

There is no research establishing a correlation between radiotherapy and its impact on the BS of a universal resin cement used in SE and SA modes to intraradicular dentin.

目的研究辐射累积剂量对自酸蚀（SE）和自粘（SA）模式下通用树脂粘结剂与牙本质的推出粘结强度（BS）的影响：根据放射治疗剂量（RT）将 48 颗人类牙齿分为三组（n = 16）：NoRT（无放射治疗）、70RT（70 Gy）和 70 + 70RT（70 Gy + 70 Gy）。根据粘合模式，牙齿被重新分为两个亚组（n = 8）：SE（NoRT-SE、70RT-SE 和 70 + 70RT-SE）和 SA（NoRT-SA、70RT-SA 和 70 + 70RT-SA）。对 BS 测试后的数据进行统计比较（方差分析、Tukey 后检验和费雪精确检验）：结果：在 SA 模式中，与 70RT 和 70 + 70RT 相比，未经过辐照的牙齿的 BS 明显更高（p 结论：SA 模式中的通用树脂粘结剂与 70RT 和 70 + 70RT 相比，BS 明显更高：在 SE 模式下，通用树脂水泥对辐照牙本质的 BS 值更高。当牙齿再次接受辐照时，无论采用哪种粘接方式，通用树脂粘接剂的BS性能都差不多：目前还没有研究证实放射治疗与通用树脂粘接剂在SE和SA模式下对牙本质BS的影响之间存在相关性。

Objectives

Evaluate the bleaching efficacy (BE) and tooth sensitivity (TS) of in-office bleaching using different application tips.

Methods

Forty-eight participants were selected (split-mouth), one to receive bleaching with an attached brush tip and one with a conventional tip. The procedure was performed with Whiteness Automixx Plus 35%. The BE was evaluated at the beginning, weekly, one and 12 months post-bleaching with a Vita Easyshade spectrophotometer (ΔE*_ab, ΔE₀₀, and WI_D) and with Vita classical A1-D4 and Vita Bleachedguide shade guides units (ΔSGU). Absolute risk and intensity of TS were recorded using the Visual Analogue Scale. The equivalence of BE was analyzed using the two one-sided t-tests for paired samples. The absolute risk of TS was evaluated using the McNemar test, and the TS intensity was measured with the paired t test (α = 0.05).

Results

The equivalence of BE was observed for both groups in all color evaluations (p > 0.05). A lower absolute risk and intensity of TS were observed for the attached brush tip when compared with the conventional tip (p < 0.003 and p < 0.0001).

Conclusion

Using an attached brush tip showed the same BE as a conventional tip. However, for the attached brush tip, there was a reduction in TS.

Clinical Significance

The applicator-attached brush tip is recommended for in-office dental bleaching, because of the possible reduction in risk and intensity of TS.

目的：评估使用不同涂抹技巧的诊所漂白效果（BE）和牙齿敏感性（TS）：评估使用不同刷头进行诊室漂白的漂白效果（BE）和牙齿敏感性（TS）：选取 48 名参与者（分口），其中一名接受附着式刷头漂白，另一名接受传统刷头漂白。漂白过程使用 35% 的 Whiteness Automixx Plus。使用 Vita Easyshade 分光光度计（ΔE*ab、ΔE00 和 WID）以及 Vita classic A1-D4 和 Vita Bleachedguide 色度指南（ΔSGU），在漂白开始时、每周、漂白后 1 个月和 12 个月对 BE 进行评估。使用视觉模拟量表记录 TS 的绝对风险和强度。采用配对样本的两个单侧 t 检验分析 BE 的等效性。TS 绝对风险采用 McNemar 检验，TS 强度采用配对 t 检验（α = 0.05）：结果：在所有颜色评估中，两组患者的 BE 值相等（P > 0.05）。与传统刷头相比，附着刷头的 TS 绝对风险和强度较低（p 结论：附着刷头与传统刷头的 TS 绝对风险和强度相同：附着式刷头与传统刷头的 BE 值相同。然而，附着式刷头的 TS 有所降低：临床意义：由于附着式刷头可降低 TS 的风险和强度，建议在诊室内进行牙齿漂白。

Yakup Atmaca DDS, PhD, Muhammet Karadas DDS, PhD

Objective

This randomized, double-blind clinical investigation assessed the performance of two high-viscosity glass-ionomer systems and a bulk-fill composite in different cavity types.

Materials and Methods

In 146 participants, 360 (class I, II, and V) cavities were restored using three different materials (Equia Forte HT, Chemfill Rock, and SonicFill 2) with equal allocation. Using modified World Dental Federation criteria, restorations were assessed after 1 week, 6 months, and 18 months by an experienced examiner. Statistical analysis was conducted using Fisher's exact and Wilcoxon signed rank tests (α = 0.05).

Results

After 18 months, 267 restorations were assessed in 116 participants. After 18 months, 5 Equia Forte HT restorations failed due to debonding and fracture. Only one loss was observed in the Chemfill Rock restorations. Equia Forte HT exhibited significantly lower retention than SonicFill 2 after 18 months (p = 0.019), irrespective of cavity type. At 1 week, 3 Class I restorations with SF showed postoperative sensitivity. The type of cavity did not affect the performance of the restorative materials used (p > 0.05).

Conclusion

Equia Forte HT and Chemfill Rock presented similar clinical performance regardless of color match. Equia Forte HT showed a lower performance compared to SonicFill 2.

Clinical significance

Glass-hybrid materials presented a lower performance in terms of color match or retention when compared to a sculptable bulk-fill composite resin.

目的这项随机、双盲临床研究评估了两种高粘度玻璃离子体系统和一种体填充复合材料在不同类型牙洞中的性能：在 146 名参与者中，使用三种不同的材料（Equia Forte HT、Chemfill Rock 和 SonicFill 2）修复 360 个（I 级、II 级和 V 级）龋洞，平均分配。修复体在 1 周、6 个月和 18 个月后，由经验丰富的检查人员按照修改后的世界牙科联盟标准进行评估。统计分析采用费雪精确检验和威尔科森符号秩检验（α = 0.05）：结果：18 个月后，对 116 名参与者的 267 个修复体进行了评估。18 个月后，5 个 Equia Forte HT 修复体因脱粘和断裂而失败。Chemfill Rock修复体仅出现了一次脱落。18 个月后，Equia Forte HT 的固位力明显低于 SonicFill 2（p = 0.019），与牙洞类型无关。1 周时，3 个使用 SF 的 I 类修复体显示出术后敏感性。龋洞类型对所用修复材料的性能没有影响（p > 0.05）：结论：无论颜色匹配与否，Equia Forte HT 和 Chemfill Rock 的临床表现相似。Equia Forte HT 的临床表现低于 SonicFill 2：临床意义：玻璃混合材料与可雕刻的大量填充复合树脂相比，在颜色匹配度或保持力方面表现较差。

Objective

Evaluate the color and translucency of a nanoceramic resin subjected to hygiene practices and immersion in coffee over time.

Materials and Methods

Specimens (n = 80, HT and LT, 0.5-mm thick) of a nanoceramic resin were obtained and were divided in groups according to the simulated oral hygiene: no intervention (NT), brushing with an electric brush and water (BN), brushing with an electric brush and toothpaste for 10 s (BT), and immersion in mouthwash for 30 s (MW). Oral hygiene practices were repeated after staining in coffee solution for 15, 48, 336, 1440, 8640, and 35,040 min. Spectral wavelengths were recorded with a spectrophotometer at each time. ∆E₀₀, ∆L′, ∆C′, ∆H′, and TP₀₀ were calculated by CIEDE2000 and were evaluated by 2-way ANOVA, repeated measures ANOVA, and Tukey's HSD test (α = 0.05).

Results

ANOVA showed significance among factors for ΔE₀₀ (p < 0.05), with higher ΔE₀₀ for NT-HT (11.7) and NT-LT (11.2). After T6 (2-year simulation), the lowest values were found for BT-HT (5.3) and BT-LT (4.9). All groups showed a reduction in lightness and translucency and increased chroma and hue. However, the smallest variations were found in the BT groups (p < 0.05).

Conclusions

Brushing with toothpaste effectively minimized the color change of NCRs caused by coffee staining.

Clinical Significance

Oral hygiene practices, such as brushing with toothpaste, might be important to minimize staining of nanoceramic resin restorations, especially in patients who frequently consume coffee.

Nilay Bayraktar DDS, Osman Tolga Harorli PhD

Objective

This study aimed to evaluate the effects of different surface treatments on the repair bond strength between a fiber-reinforced dentin composite and a posterior composite.

Methods

Forty fiber-reinforced dentin composite resin blocks (4 mm × 4 mm × 4 mm) were separated into eight groups (n = 5) according to the surface preparation methods: (G1) negative control group, (G2) adhesive application, (G3) 50% dimethylsulfoxide (DMSO) application, (G4) 50% DMSO + adhesive application, (G5) 37% phosphoric acid etch + adhesive application, (G6) air abrasion + adhesive application, (G7) 37% phosphoric acid etch + 50% DMSO application + adhesive application, and (G8) air abrasion +50% DMSO application + adhesive application group. The composite surfaces were repaired in two layers with a posterior composite. Composite sticks were subjected to a micro tensile bond strength (μTBS) test. Fractured surfaces were evaluated using a stereomicroscope (×25). Short fiber-reinforced composite samples' surfaces were investigated by scanning electron microscope (SEM). Shapiro Wilk, one-way ANOVA, and Tukey HSD tests were used for statistical evaluation.

Results

The highest average (μTBS) values were observed in G8, whereas the lowest mean μTBS values were evident in the G1 group. Statistically significant μTBS values were found in all adhesive-applied groups when compared with the negative control group. Notably, the application of 50% DMSO without adhesive did not lead to a statistically significant increase in μTBS values. SEM images demonstrated that acid etching partially eliminated residues on the composite surface, while air abrasion had a detrimental effect on the integrity of fiber structures.

Conclusion

In the repair of fiber-reinforced dentin composite with a posterior composite, adhesive application is an effective approach. The treatment of 50% DMSO without adhesive did not confer a statistically significant advantage, and the supplemental use of acid etch or air abrasion did not show an additional benefit compared to adhesive-only repairs.

Clinical Significance

Adhesive application emerges as a potent and effective strategy for the repair of bur-roughened fiber-reinforced dentin composites. With its limitations, the study highlights the efficacy of adhesive-only rep

研究目的本研究旨在评估不同表面处理方法对纤维增强牙本质复合材料与后道复合材料之间修复粘接强度的影响：将 40 个纤维增强牙本质复合树脂块（4 mm × 4 mm × 4 mm）按表面处理方法分为 8 组（n = 5）：(G1）阴性对照组；（G2）粘接剂涂抹组；（G3）50%二甲基亚砜（DMSO）涂抹组；（G4）50%二甲基亚砜+粘接剂涂抹组；（G5）37%磷酸腐蚀+粘接剂涂抹组；（G6）空气研磨+粘接剂涂抹组；（G7）37%磷酸腐蚀+50%二甲基亚砜涂抹+粘接剂涂抹组；（G8）空气研磨+50%二甲基亚砜涂抹+粘接剂涂抹组。复合材料表面用后复合材料修复了两层。对复合材料棒进行微拉伸粘接强度（μTBS）测试。使用体视显微镜（×25）对断裂表面进行评估。短纤维增强复合材料样品的表面由扫描电子显微镜（SEM）进行研究。采用 Shapiro Wilk、单因素方差分析和 Tukey HSD 检验进行统计评估：G8 组的平均 μTBS 值最高，而 G1 组的平均 μTBS 值最低。与阴性对照组相比，所有粘合剂组的 μTBS 值均具有统计学意义。值得注意的是，在不使用粘合剂的情况下，使用 50%的二甲基亚砜并不会导致μTBS 值出现统计学意义上的显著增加。扫描电子显微镜图像显示，酸蚀可部分消除复合材料表面的残留物，而气蚀对纤维结构的完整性有不利影响：结论：在用后牙复合材料修复纤维增强牙本质复合材料时，使用粘合剂是一种有效的方法。不使用粘合剂而使用 50%二甲基亚砜进行处理在统计学上没有显著优势，与仅使用粘合剂修复相比，辅助使用酸蚀或气磨也没有显示出额外的益处：临床意义：应用粘合剂修复毛刺粗化的纤维增强牙本质复合材料是一种有效的策略。临床意义：这项研究表明，粘合剂应用是修复毛刺粗化纤维增强牙本质复合材料的有效方法，尽管有其局限性，但它强调了纯粘合剂修复的有效性，而无需额外的表面处理。
