“…This may have resulted from the positive effects of silanization of the post and the dentine surface being conditioned with acid etching. This result is partially consistent with Sahinkesen et al [ 21 ] who reported that Variolink II and silanization of the post combination achieved the highest bond strength values. However, other silane coupling agent groups (Postec Plus/RelyX Unicem) demonstrated the lowest mean bond strength values.…”

Objective: The aim of this study was to compare the resistance to vertical root fracture of root-filled teeth restored with four different fiber-reinforced composite (FRC) post systems and two types of dual-cured resin luting agents. Materials and Methods: Ninety extracted human maxillary central incisors were selected and decoronated to obtain a standardized root length of 14 mm. After root canal obturation, post spaces were prepared to a depth of 10 mm with a No. 3 post drill. The specimens (n = 80) were divided into two groups (n = 40) according to the resin luting agents used: group 1, Variolink II + ExciTE DSC; group 2, RelyX Unicem. These groups were subdivided into four subgroups (n = 10) and restored with one of the following post systems: (a) DT Light, (b) DT Light SL, (c) FRC Postec and (d) Everstick, while the remaining 10 teeth served as controls. The roots were subjected to axial compressive loading using a 2.2-mm-diameter metal sphere in a universal testing machine (0.5 mm/min). A factorial experiment with a single control group (analysis of variance) was used to test the resistance of the specimens. Results: Groups 2a (DT Light + RelyX Unicem; 398.5 N) and 1b (DT Light SL + Variolink II + ExciTE DSC; 431.1 N) had significantly higher resistance to fracture than the control group (334.1 N; p < 0.05). DT Light SL and FRC Postec Plus were more resistant to fracture when Variolink II was used as the luting cement. DT Light and Everstick had higher fracture resistance when they were luted with RelyX Unicem (p < 0.05). Conclusion: The results of this study indicate that the use of quartz fiber posts (DT Light and DT Light SL) with an adhesive luting cement in root-filled teeth may reinforce the root to some extent.

“…It was suggested that such lower degrees of conversion result in lower bond strengths at those root-canal depth levels at which photoactivation is ineffective. [17][18][19][20][21][22][23][24][25][26]30 In the group in which the light was directly applied to the apical area of the root canal, the bond strength showed significant improvement. Studies have shown that in the apical third, dentin exhibits conditions that are less favorable for adhesion, 14,16 such as a lower number of dentinal tubules, [12][13][14] and a greater probability of presenting endodontic treatment remnants.…”

“…16 Techniques for post cementation based on resin infiltration in the interior dentinal tubules are more sensitive and less predictable in the apical area. 14,16 Although several studies [17][18][19][20][21][22][23][24][25][26] have shown that resin cement bond strengths inside the apical third of the post space preparations are lower than those at the cervical third, some authors [27][28][29] were unable to confirm this difference. Thus, it is important to investigate the factors influencing bond strength of resin cements in the apical third of the post space preparation, emphasizing the role of photoactivation and dentinal substrate in that root canal area.…”

B Daleprane C Nemesio de Barros Pereira RL Oréfice AC Bueno RR Vaz AN Moreira CS Magalhã es Clinical RelevanceCementation of fiber glass posts with self-adhesive cement (RelyX U100) is more predictable than cementation with resin cement using a three-step etch-and-rinse adhesive system (RelyX ARC/SBMP) as its bond strength to apical dentin was not influenced by the level of light-curing access. SUMMARYPurpose: This study evaluated the effect of light-curing access on the bond strength of fiber glass posts to the apical area of bovine roots using self-adhesive cement or dual-cured cement with an etch-and-rinse adhesive system.Materials and Methods: The root canals of 60 bovine teeth were endodontically treated and filled. A 15-mm-length post space was prepared and roots were randomly divided into three groups, simulating the levels of light-curing access: coronal (C), with 15-mm post space; middle (M), in which the coronal thirds of roots were cut out, leaving a 10-mm post space; and apical (A), in which the coronal and middle thirds of roots were cut out, leaving a 5-mm post space. Fiber glass posts (Reforpost # 3, Angelus) were cemented with RelyX U100 (3M ESPE) or RelyX ARC/Scotchbond Multi Purpose Plus (SBMP) (3M ESPE) (n=10) and lightcured. After 24 hours, the apical thirds of roots were sectioned perpendicularly to the long axis and submitted to a push-out test (0.5 mm/

“…The category of adhesive procedures includes the use of posts to root dentin to stabilize direct and indirect restorations in teeth that have suffered severe destruction 1,2 , when there is remaining healthy dentin of the crown height and length [3][4][5][6] . The fiberglass post is compatible with the resin materials commonly used in adhesive procedures 7,8 and so, the bonding may be enhanced when associated with adhesive cements [9][10][11] . The low incidence of root fracture is advantageous, due to the similar elastic modulus between the post and the dentin 12,13 .…”

Bonding of fiber posts using self-adhesive resin cement to radicular dentin is controversial. The aim was to evaluate the effect of conditioning of polyacrylic acid on the longevity of bonding of self adhesive resin cement to dentin. Thirty six single rooted pre molars were divided into 3 groups (n=12) ARC: ScotchBond Multi Purpose + RelyX™ARC; U: RelyX™U200; PU: 11.5% Polyacrylic acid + RelyX™U200. After conditioning of the dentin, the resin cement and the post were inserted and light-activated for 60s (1200mw/cm2) and stored in distilled water (24h/37ºC). Two discs of 1 mm thickness were obtained from each root-third and tested in push-out (0.5mm/min) after 24 hours and 6 months. For statistical purposes, the data from the root thirds were grouped and the bond strength (in MPa) was analyzed using Two-Way Analysis of Variance and Tukey’s post-hoc test at 5%. The power of the test was calculated. The bonding of the U at 6 months was higher than PU at both times (p<0.001). There were no differences for time (p=0.153) or for the interaction of treatment x time (p=0.090). Adhesive fractures between the cement and dentin were prevalent. The power test was 0.97. The bonding of the RelyX™U200 was influenced by the dentin pre-treatment with poliacrylic acid and the bonding of all groups remained stable for 6 months.Keywords: Dental Cements. Dentin. Shear Strength.ResumoA adesão de pino de fibra de vidro com cimento resinoso autoadesivo à dentina é controversa. Foi objetivo avaliar o efeito do condicionamento da dentina com ácido poliacrílico na longevidade da adesão de cimento resinoso autoadesivo. Trinta e seis raízes de pré-molares uni radiculados foram divididas em 3 grupos (n=12) ARC: ScotchBond Multi Purpose + RelyX™ARC; U: RelyX™U200; PU: Ácido poliacrílico 11,5% + RelyX™U200. Após condicionamento da dentina, o cimento resinoso e o pino de fibra de vidro foram inseridos, fotoativados por 60s (1200mw/cm2) e armazenados em água destilada (24h/37ºC). Dois discos de dentina de 1 mm de espessura foram obtidos de cada terço radicular e testados em push-out (0.5mm/min) após 24 houras e 6 meses. Para análise estatística, os dados dos terços radiculares foram agrupados e resistência adesiva (em MPa) analisada por Análise de Variância de dois fatores e teste de Tukey a 5%. O poder do teste foi calculado. A adesão de the U após 6 meses foi maior que a de PU nos dois períodos (p<0,001). Não houve diferença para o fator tempo (p=0,153) nem para a interação tratamento x tempo (p=0,090). Fraturas adesivas prevaleceram entre cimento e dentina. O poder do teste calculado foi de 0,97. A adesão do RelyX™U200 foi influenciada pelo pré-tratamento da dentina com ácido poliacrílico e a adesão de todos os grupos se manteve estável até 6 meses.Palavras-chave: Cimentos Dentários. Dentina.
