“…41 In contrast to the findings of this study, it was observed that Admira Protect increased the bond strength of resin cements. 41 Potassium fluoride reacts with the dentinal fluid and causes precipitation of calcium ions and proteins in the dentinal fluid that block the tubules. 42 SEM findings and mean bond strength values of this study same line with present study.…”

The aim of this study was to evaluate how microshear bond strength of different adhesive resin cements are affected by dentin desensitizers application and preparation depth. Materials and Methods: One hundred and forty-four maxillary incisors were randomly divided into two groups according to dentin preparation depth (0.8 and 1 mm) and each group subdivided into four dentin desensitizers, Nd:YAG (Neodymium-doped Yttrium aluminum Garnet) laser and control groups. The dentin desensitizers used were Gluma [Glutaraldehyde/ Hydroxyethyl methacrylate (HEMA)], BisBlock (Oxalate) Vivasens-Potassium Fluoride (KF) and Admira Protect (Ormocer/HEMA), respectively. Three dual cure resin based luting cement (RelyX ARC; Variolink II and Maxcem Elite) were used to create a 0.7 mm diameter and 1 mm height cylindirical shape buid-up in tygon tubes (n=10). Micro-shear bond strength (µSBS) test was performed at a crosshead of speed of 0.5 mm/min using a Universal testing device. Then tooth surface was investigated by steromicroscope and scanning electron microscopy (SEM). Data were analyzed using Kruskal-Wallis, Mann-Whitney U and Chi-Square (X 2) tests. (p = 0.05) Results: There was no statistically difference between the groups at 0.8 mm preparation depth. At 1 mm preparation dept RelyX ARC + Gluma groups' mean bond strength value (23.96 ± 6.66 MPa) was found statistically lower according to the other groups (p<0.05). RelyX ARC + Laser groups' mean bond strength value (37.33 ± 7.39 MPa) was found statistically higher according to the other groups (p<0.05). Conclusions: The use of desensitizing agents affected the bond strength of the resin cements to superficial dentin. Gluma desensitizer affected negatively µSBS of RelyX ARC resin cement at 1 mm depth. Application of Nd:YAG laser to superficial dentin showed positive effects to the dentin surface and bond strength. Other desensitizing agents showed no significant effects on the resin bond strength (p>0.05).

“…Studies have shown that the application of fluoride desensitizers did not affect the bond strength of self-etch adhesive systems to demineralized dentin, in agreement with the results found in the present study, although an etch-and-rinse adhesive system was used [29]. On the other hand, recent studies have shown a reduction in bond strength of adhesives to sound dentin after desensitization protocols, but this is inversely related to the fluoride concentration in the compound, because higher concentrations reduce the bond strength due to crystals precipitating on the dentin surface [30,31]. Moreover, bond strength was not affected in the groups containing fluoride as desensitizer due to the concentrations being relatively low: 2% in Desensibilize KF2%, 0.25% in Ultra EZ and 0.9% in Nano P.…”

This study aims to compare the in vivo effect of a desensitizing therapy associated with a restorative technique for the treatment of cervical dentin hypersensitivity (CDH) in non-carious lesions. The sample consisted of 68 teeth with moderate or severe dentin hypersensitivity in 17 individuals (one tooth per quadrant). The sensitivity levels of the teeth were scored, and the teeth were randomly distributed into four groups: T1 -desensitizing gel applied once per week until remission of pain; T2 -desensitizing gel applied once per week followed immediately by restoration with resin composite (Filtek Z250, 3M Espe); T3 -desensitizing gel once per week until remission of pain and then restoration with resin composite; and T4 -restoration with resin composite. Dentin hypersensitivity was assessed at 0, 7, 30, 90 and 180 days. The Kruskal-Wallis, Wilcoxon and Mann-Whitney (p < 0.05) tests were used to compare the treatments. The mean baseline CDH scores were T1 -2.41, T2 -2.41, T3 -2.47, and T4 -2.70 (p > 0.05). At seven and 180 days, the mean CDH scores were as follows: T1 -1.47/0.65, T2 -1.35/0.71, T3 -0.71/0.53, and T4 -1.12/0.59, all of which were significantly lower (p < 0.001) than the baseline scores. The scores at 30, 90 and 180 days were not significantly different when compared to the score of the previous period. At 180 days, CDH scores were similar among groups (p > 0.05). Teeth with moderate or severe hypersensitivity that required a filling responded similarly regardless of whether the desensitizing procedure was carried out prior to the filling.
