“…Previous studies have demonstrated that the hybrid layer formed in CHX-treated dentin exhibits a normal structural integrity of the collagen network, contrary to untreated substrate; however, it is smaller and less consistent [27,28]. In the present study, these features were not translated in reduction of the bond strength.…”

“…On the contrary, other studies have reported that CHX may interfere with the infiltration ability of the hydrophilic monomers through the dentinal tubules; fact that over time, can lead to decrease in the bond strength and increase in microleakage [27,28]. Acid etching prior to the use of conventional adhesive systems promotes deeper infiltration into dentin [30]; so, probably CHX could infiltrate more easily through the dentinal tubules and interfere with the bonding procedure, impeding the formation of a uniform hybrid layer and presenting fewer resin tags (as seen in Figure 4E and 4F).…”

This study evaluated the influence of thermo-mechanical cycling (TMC) on the bond strength (BS) of a universal adhesive system (UAS -Adper Single Bond Universal, 3M ESPE) to dentin treated or not with 0.2% chlorhexidine (CHX). Methods: Eighty human molars were flattened until reach the dentin and separated into 4 groups according to the bonding protocol: ENR Group: 37% phosphoric acid þ 3-step etch-and-rinse adhesive system (ENR); UAS Group:After treatments, teeth were restored (Filtek Z350, 3M ESPE). Samples (n ¼ 10) were submitted to aging process: stored in distilled water at 37 C/30 days or TMC (ERIOS -98N/1.6Hz þ thermal cycling 5/37/ 55 C -1,200,000 cycles). Specimens were sectioned into sticks (1.0 mm 2 ) and submitted to the microtensile test (Mechanical Test Machine -0.5 mm/min). Fracture patterns and hybrid layer integrity were analyzed under Stereomicroscope and Scanning Electron Microscopy (SEM). Results:The BS results (3-way ANOVA, Bonferroni's test, α ¼ 5%) showed that groups treated with CHX presented higher BS values than control groups; significant in all cases (p < .05), except for ENR submitted to TMC (p > .05). When CHX was applied and samples were cycled, UAS revealed higher BS (p < .05) than ENR. After TMC, cohesive fractures increased for UAS, regardless of CHX application. SEM analysis demonstrated different hybridization patterns for the adhesive systems tested. Conclusion:The performance of the universal adhesive system used in self-etch mode was better than that of the 3step etch-and-rinse adhesive system. Clinical significance: Universal adhesive systems have been developed in order to simplify the dentin hybridization protocol. It is important to determine the longevity of the adhesive interface using these bonding materials after chewing.

Background: Lack of bond stability between the composite resin and dentin remains one of the main reasons for having to replace esthetic restorations. Aim: This study aimed to evaluate the influence of chlorhexidine (CHX) on the bond strength of a total etching system to dentin tissue after degradation of the adhesive interface. Materials and Methods: One hundred and eighty fragments of human molars were divided into three groups ( n = 15) according to the materials used during the acid-etching step: Group 1 (control), 37% phosphoric acid; Group 2, a combined solution of 37% phosphoric acid and 2% CHX; and Group 3, 37% phosphoric acid followed by 2% CHX. Following the restorative procedures, the groups were divided into four subgroups according to the number of thermal cycles (TC) and to the time of storage in water (SW), and then subjected to a shear strength test, until fracture: (A) 0 TC/24-h SW; (B) 500 TC/1-week SW; (C) 2,000 TC/1-month SW; and (D) 12,000 TC/6-month SW. Two-way analysis of variance and Duncan's complementary test were used to perform multiple comparisons. Results: After the 24-h and 1-week SW time periods, no statistically significant difference was found among the shear strength values of the control and the experimental groups: 5.48 ± 0.59 MPa, 5.44 ± 0.56 MPa, and 5.65 ± 0.94 MPa for G1, G2, and G3, respectively. However, the shear strength values decreased significantly in all the study groups after 1 month, namely 3.60 ± 0.41 MPa, 3.08 ± 0.65 MPa, and 3.49 ± 0.23 MPa for G1, G2, and G3, respectively. After 6 months, similar results were found for G1 and G3, namely 2.77 ± 0.58 MPa and 1.74 ± 0.52 MPa, respectively, whereas the 0.77 ± 0.26 MPa value found for G2 was significantly lower than those found for the G1 and G3 groups. No differences were found between the groups with respect to fracture-type frequencies. Conclusion: The use of CHX as an agent to rehydrate the dentin had a negative influence on bond strength.

Background: Cleaning the cavity before restoration with the application of disinfection material, namely the cavity cleanser, aims to remove debris, bacteria, which colonize or proliferate in the smear layer of the cavity. Chlorhexidine digluconate disinfection agent is antimicrobial, and NaOCL (sodium hypochlorite) has antibacterial properties and can dissolve organic tissue, so NaOCL is combined with EDTA to remove inorganic tissue. Purpose: To compare the shear strength of bioactive composite resin between 2% chlorhexidine digluconate and 5% NaOCL + 17% EDTA as a cavity cleanser. Methods: This study was divided into three treatment groups, the first group was chlorhexidine digluconate 2% before etching, the second group was application of NaOCL 5% + EDTA 17% before etching, and the third group without application of cavity cleanser before etching. The cavity is then filled using bioactive composite resin. The shear strength test was carried out using a universal testing machine. Results: One-way ANOVA test showed that there was no significant difference between treatment groups (p> 0.05). Conclusion: There is no significant difference in the shear strength of bioactive composite resin with the application of 2% chlorhexidine digluconate before etching, 5% NaOCL + 17% EDTA before etching, and without the application of cavity cleanser before etching. Key words: Bioactive composite resin; cavity cleanser; Chlorhexidine digluconate 2%, NaOCl 5% dan EDTA 17%. ABSTRAKLatar belakang: Pembersihan kavitas sebelum restorasi dengan aplikasi bahan desinfeksi yaitu cavity cleanser bertujuan untuk menghilangkan debris, bakteri, yang berkolonisasi atau proliferasi dalam smear layer pada kavitas setelah dipreparasi. Bahan desinfeksi klorheksidin diglukonat bersifat antimikroba dan NaOCL (Natrium hipoklorit) sifat antibakteri dan dapat melarutkan jaringan organik, sehingga NaOCL digabung dengan EDTA untuk menghilangkan jaringan anorganik. Tujuan: Membandingkan kekuatan geser resin komposit bioaktif antara Klorheksidin diglukonat 2% dan NaOCL 5%+EDTA 17% sebagai cavity cleanser. Metode Penelitian: Penelitian ini terbagi menjadi tiga kelompok perlakuan, kelompok pertama adalah klorheksidin diglukonat 2% sebelum pengetsaan, kelompok kedua yaitu aplikasi NaOCL 5%+EDTA 17% sebelum pengetsaan, dan kelompok ketiga tanpa aplikasi cavity cleanser sebelum dietsa. Kavitas kemudian ditumpat menggunakan resin komposit bioaktif. Uji kuat geser dilakukan dengan menggunakan universal testing machine. Hasil: Uji one-way ANOVA menunjukkan bahwa tidak terdapat perbedaan yang bermakna antar kelompok perlakuan (p>0.05). Kesimpulan: Tidak terdapat perbedaan bermakna kekuatan geser resin komposit bioaktif dengan aplikasi klorheksidin diglukonat 2% sebelum pengetsaan, NaOCL 5%+EDTA 17% sebelum pengetsaan, dan tanpa aplikasi cavity cleanser sebelum dietsa. Kata kunci: Resin komposit bioaktif; cavity cleanser; Klorheksidin diglukonat 2%, NaOCl 5% danEDTA 17%.
