“…This result is supported by other studies, although they compensate high power density by a decrease of exposure time. 21,22 The results of the present study suggest that shear bond strength did not increase proportionally with power density. An exponential fit was found to capture their relationship best.…”

“…3,4 Most studies have shown that RMGIC are more effective for preventing the demineralization of enamel than both fluoride-releasing and non-fluoride-releasing composite resin adhesive systems, 1,5,8 although previous studies have shown that RMGIC has a lower bond strength than composite resin adhesives. 3,4 Recently, the release of calcium ion and changes in pH with MTA have been studied 25 ; the bioactivities of MTA and PC have been attributed to their ability to produce hydroxyapatite 10 or carbonate apatite 11 in the presence of phosphate-buffered saline. In the present study, new resin-based bracket-bonding adhesive containing PC powder successfully inhibited the demineralization of enamel in vitro, and its remineralization ability was equivalent to that of RMGIC.…”

“…Most studies have shown that RMGIC are more effective for preventing the demineralization of enamel than both fluoridereleasing and non-fluoride-releasing composite resin adhesive systems, 1,5,6 although RMGIC was shown to have a weaker bond strength than composite resin adhesives. 3,4 Mineral trioxide aggregate (MTA), which is composed of tricalcium silicate (53%), dicalcium silicate (23%), bismuth oxide (22%) and small amounts of tricalcium aluminate and calcium sulphate, was introduced to dentistry in the mid-1990s by Dentsply Tulsa Dental (Tulsa, Okla). 9 According to the manufacturer, MTA can be used for root-end filling, apexification, repair of perforations, and direct pulp capping.…”

“…2 Over the past decade, resin-modified glass ionomer cements (RMGIC) with improved bracket bond strength have been developed. 3,4 The cariostatic potential of adhesives adjacent to brackets has been investigated both in vitro 1,5,6 and in vivo 7,8 by quantifying the depth of demineralization and mineral loss by various evaluation methods. Most studies have shown that RMGIC are more effective for preventing the demineralization of enamel than both fluoridereleasing and non-fluoride-releasing composite resin adhesive systems, 1,5,6 although RMGIC was shown to have a weaker bond strength than composite resin adhesives.…”

Objective: To determine if a new experimental resin-based material containing Portland cement (PC) can help prevent enamel caries while providing adequate shear bond strength (SBS). Materials and Methods: Brackets were bonded to human premolars with experimental resinbased adhesive pastes composed of three weight rations of resin and PC powder (PC 30, 7:3; PC 50,5:5; PC 70, 3:7; n 5 7). Self-etching primer (SEP) adhesive (Transbond Plus) and resinmodified glass ionomer cement (RMGIC) adhesive (Fuji Ortho FC Automix) were used for comparison. All of the bonded teeth were subjected to alternating immersion in demineralizing (pH 4.55) and remineralizing (pH 6.8) solutions for 14 days. The SBS for each sample was examined, and the Adhesive Remnant Index (ARI) score was calculated. The hardness and elastic modulus of the enamel were determined by a nanoindenter at 20 equidistant depths from the external surface at 100 mm from the bracket edge. Data were compared by one-way analysis of variance and a chi-square test. Results: PC 50 and PC 70 showed significantly greater SBS than Fuji Ortho FC Automix, although Transbond Plus showed significantly greater SBS than other bonding systems. No significant difference in the ARI category was observed among the five groups. For specimens bonded with PC 50 and PC 70, the hardness and elastic modulus values in most locations were equivalent to those of Fuji Ortho FC Automix. Conclusions: Experimental resin-based bonding material containing PC provides adequate SBS and a caries-preventive effect equivalent to that of the RMGIC adhesive system.

“…However, this optimizes the clinical time by not requiring light cure action. 21 It is not easy to quantify the ideal adhesive strength for bonding orthodontic accessories. It is known that there must not be extremely low or too high, so that the debonding does not cause fractures in the enamel surface.…”

Objective: To evaluate, in vitro, the shear bond strength of self-curing (Concise TM -3M and Alpha Plast -DFL) and light-curing composites (Transbond TM XT -3M and Natural Ortho -DFL) used in orthodontics bonding, associated to Morelli metal brackets, with further analysis of adhesive remnant index (ARI) and enamel condition in scanning electron microscopy (SEM). Methods: Forty human premolars, just extracted and stored in physiologic solution 0.9 % were used. Randomly, these samples were divided in four groups: G1 group, the brackets were bonded with Concise TM -3M composite; in G2 group, Alpha Plast -DFL composite was used; in G3 group, Transbond TM XT -3M was used; in G4 group, Natural Ortho -DFL composite was used. These groups were submitted to shear strength tests in universal testing machine, at 0.5 mm per minute speed. Results: Statistical difference between G3 and G4 groups was recorded, as G4 showing higher strength resistance than G3. In the other hand, there were no statistical differences between G1, G2 and G3 and G1, G2 and G4 groups. ARI analysis showed that there was no statistical difference between the groups, and low scores were recorded among then. The scanning electron microscopy (SEM) analysis revealed the debonding spots and the enamel surface integrity. Conclusions: Shear bond strength was satisfactory and similar between the composites, however Natural Ortho -DFL revealed best comparing to Transbond TM XT -3M. Keywords: Composite resins.

Objetivo: avaliar in vitro a resistência ao cisalhamento de compósitos autopolimerizáveis (Concise e Alpha Plast) e fotopolimerizáveis (Transbond XT e Natural Ortho) utilizados na colagem de braquetes metálicos da marca Morelli, analisando o índice de adesivo remanescente (ARI) e da integridade da superfície do esmalte por meio de microscopia eletrônica de varredura (MEV). Métodos: foram utilizados 40 pré-molares humanos extraídos. As raízes dos dentes foram incluídas em gesso-pedra especial, no interior de tubos de PVC usados para a confecção dos corpos de prova. Esses corpos de prova foram divididos em quatro grupos: grupo G1, braquetes associados ao compósito Concise; grupo G2, braquetes associados ao compósito Alpha Plast; grupo G3, braquetes associados ao compósito Transbond XT; e grupo G4, braquetes associados ao compósito Natural Ortho. Os grupos foram submetidos ao teste de cisalhamento em máqui-na universal de ensaios, a uma velocidade de 0,5mm por minuto. Resultados: houve diferença estatística entre os grupos G3 e G4, sendo os valores de G4 superiores; no entanto, não foram encontradas diferenças estatisticamente significativa...
