Adhäsive Befestigung

ZusammenfassungSowohl für die Befestigung von Brackets als auch von Aligner-Attachments stehen verschiedene Materialien und Strategien zur Auswahl. Die Vorbereitung der Schmelz-Oberfläche für die adhäsive Befestigung kann mit Phosphorsäure im Etch and Rinse-Verfahren oder mittels diverser selbstätzender Adhäsive vorgenommen werden. Die Materialien zur Befestigung unterscheiden sich hinsichtlich der Monomermatrix, der Füllkörper und deren Anteile sowie ihres Initiatiorsystems. Brackets können direkt oder indirekt adhäsiv befestigt werden. Attachments für die Behandlung mit Alignern können ein- oder zweiphasig auf die entsprechenden Zähne aufgebracht werden. Ziel dieses Artikels ist es, anhand der aktuellen Literatur einen Überblick über die verschiedenen Materialien und Befestigungsstrategien zu geben.

This study evaluates and compares by dye penetration method and SEM photomicrographs the sealing obtained using two different classes of adhesive systems (etch-and-rinse and self-etch with selective etching) with SDR (Dentsply) bulk fill composite. 84 class V cavities were prepared on oral and vestibular face of 42 intact, freshly extracted wisdom teeth. The cavities were randomly divided in two groups and restored: Group 1 with prime &bond one select (Dentsply) and SDR (Dentsply) and Group 2 with prime&bond one Etch&Rinse (Dentsply) and SDR (Dentsply). Prime&bond one Select (Dentsply) is a single component adhesive and can be used in self etch mode, in selective enamel etch mode, or in etch-and-rinse mode. We chosen for this study the selective etch of the enamel mode. Prime&bond one Etch Rinse (Dentsply) is a universal etch-and-rinse one-bottle dental adhesive, designed to be used in two steps. The bulk fill composites are commonly used in modern dentistry due to their properties of low polymerization shrinkage and curing in layer of 4 mm depth, offering the practitioner a fast clinical procedure with good results. The results showed a good sealing at enamel and dentin margins with no statistically significant difference between adhesives, even though the mean of enamel infiltration was smaller for Group1. Furthermore the results show that there were differences between the two groups, for the infiltrations at the enamel, the values of microleakage being arithmetically higher for Group 1, but with no statistically difference between the two groups.SEM images showed for both groups a good adhesion surface with the tooth, but the hybrid layer of the total-etch adhesives is different from the hybrid layer formed by self etch adhesives, in terms of thickness, uniformity. In conclusion both adhesive systems have equivalent sealing qualities and can be successfully used with SDR.

The aim of this study was to evaluate the efficiency of laser therapy in post-operative sensitivity by Visual Analogue Scale (VAS) to the 57 patients after restoration with two different resins composite. In the first group (28 patients, 30 teeth) it was restored the cavity class I Black with micro-hybrid composite Filtek Z250 - Adper Single Bond (3M/ESPE). In the second group (29 patients, 30 teeth) it was restored the cavity class III Black with nano-hybrid composite Ceram X One Sphere Tec-Prime and Bond One (Etch&Rinse) (Dentsply). The restorative treatments were performed by the same practitioner on posterior and anterior teeth diagnosed with mid-sized chronic carious lesions. Total etch (etch and rinse) strategy of adhesion was used for both composite resins. The laser treatment was performed in 2 sessions at 48 hours and after 7 days, for both study groups using laser Whitening Lase II (DMC Dental). Mean scores for VAS indices decreased significantly at 48 hours and 7 days, following laser treatment for all the investigated parameters (materials, sex, age) (p [ 0.05).

Objective: The objective of this review was to evaluate the effect of non-thermal atmospheric plasma (NTAP) on adhesives resin–dentin micro-tensile bond strength (μTBS) in previously published studies. Methods: Electronic search was conducted using the Medline, Cochrane library, and Scopus databases. The included studies were laboratory studies that investigated the effect of NTAP on adhesives μTBS to coronal dentin. Studies that evaluated the effect of NTAP on bond strength to indirect substrates, enamel or root dentin, were excluded. The methodological quality of included studies was assessed. Results: Thirteen studies were included in this systematic review. All the included studies were considered to have a medium risk of bias. NTAP significantly improved μTBS at 24 h or after short-term aging in five studies (38.5%) and both immediate and after long-term aging in 5 studies (38.5%). In two studies (15.4%), NTAP resulted in a short-term material-dependent effect that was not stable after long-term aging. Interestingly, in one study (7.7%), NTAP had a positive effect only in the etch-and-rinse (ER) mode after long-term aging. Conclusion: Within the limitations of this systematic review, NTAP application could enhance resin–dentin μTBS of ER adhesives or universal adhesives (UAs) applied in the ER mode. In the ER mode, the rewetting step after NTAP seems to be unnecessary. Because of the limited information currently available in the literature, further studies are required to evaluate the effect of the NTAP application on self-etch (SE) adhesives or UAs applied in the SE mode.

Abstract The aim of this study was to evaluate in vitro the influence of 20% glycolic ginger extract on the bond strength of glass-fiber post cemented with etch-and-rinse or self-etching resin cement. Forty-eight bovine roots were standardized (17±0.5 mm) and randomly divided into two groups, according to irrigant used during biomechanical preparation: NaOCl: 1% sodium hypochlorite and GEN: 20% glycolic ginger extract. Root canal was prepared and randomly assigned to one of two subgroups (n=12), according to luting protocol: self-etching (RelyX U200) and etch-and-rinse (RelyX ARC). After 48 h, the roots were sectioned perpendicularly (4 in cervical third and 3 in middle third) and submitted to push-out bond strength test (50 kgf load cell, 1.0 mm/min). Failure mode was analyzed in SEM and stereomicroscopy. Data were analyzed by three-way ANOVA and Tukey tests (p<0.05). ANOVA revealed that there were no significant differences between U200 (2.01±0.17)B and ARC (1.93±0.12)B in GEN group, and at the cervical third for both irrigants, 2.69±0.16A and 2.54±0.17A, respectively. Middle third showed lower bond strength than cervical third, regardless the irrigant. Overall, the cervical third regardless the irrigant employed and the association between NaOCl and ARC, presented better adhesive performance.
