“…30 It also can dissolve inorganic and organic tissues and remove the smear layer. 32 A more recent study has demonstrated that ClO 2 solution can be preferred as a deproteinizing agent to enhance the dentin bond strength of hypocalcified amelogenesis imperfecta-affected primary teeth. 33 However, to the best of our knowledge, there is no information available regarding how deproteinization on dentin bond strength in permanent teeth is affected by ClO 2 .…”

Aim: To evaluate the effects of papain (Brix 3000), bromelain, sodium hypochlorite (NaOCl), and chlorine dioxide (ClO2) application to the deep dentin surface on shear bond strength (SBS), microleakage, and dentin surface properties. Materials and Methods: Deep dentin surface ( n = 100) for evaluating SBS, class V preparation at the buccal surface for testing microleakage ( n = 100), and deep dentin slices ( n = 20) for evaluating surface properties were conducted on the 220 molar teeth. Four different deproteinizing agents (Brix 3000, 40% bromelain, 5.25% NaOCl (Chloraxid), and 0.12% ClO2) were applied to the dentin, and then the universal adhesive was used in self-etch (SE) and etch&rinse (E&R). Deproteinizing agents were not applied to the control group. All of the samples were subjected to 5000 cycles of thermal aging at 5ºC–55ºC. SBS (MPa) was tested by a universal testing machine. The microleakage of resin composite bonded with different adhesive modes was evaluated under a stereomicroscope. The changes in the surface morphology were examined with scanning electron microscopy (SEM) and attenuated total reflection – fourier transform infrared spectroscopy (ATR-FTIR). Results: ClO2 exhibited the highest bond strength among deproteinizing agents. Compared to the SE mode, E&R mode significantly showed higher bond strength ( p < .05). In gingival margin, bromelain SE exhibited the highest marginal leakage, while Brix 3000 SE had the lowest mean microleakage score. Conclusion: Deproteinizing with ClO2 was effective in improving the SBS of universal adhesive in the E&R mode to deep dentin. Deproteinization with bromelain before universal adhesive in SE mode showed more microleakage on both the occlusal and gingival surfaces.

“…Citric acid is a weak organic acid used in endodontic therapy because of its effectiveness in dissolve the smear layer as well as the inorganic components of root dentine with no or little effect on organic components (7) . Citric acid has a chelating action similar to EDTA "ethylenediamine tetra-acetic acid" but with lower cytotoxicity on preapical tissues (8) .…”

Objectives: In primary teeth, the clinical success of pulpectomy depends on the eradication of pathogenic microorganisms from the infected canals. Thus, this study was directed to evaluate the antimicrobial effect of citric acid and chitosan in comparison with sodium hypochlorite (NaOCl) on E. faecalis. Subjects and Methods: A total of 30 children aged between 4-7 years were included in the present study. The enrolled children had primary carious teeth that were indicated for pulpectomy treatment. The involved teeth were categorized into three main groups according to the type of irrigant solution; 6% citric acid (A), 6% chitosan (B), and 1% NaOCl (C). Then each main group was further subdivided into non-activated (A1, B1, and C1) or ultrasonic activated (A2, B2, and C2). E. faecalis count was carried out using a colony-forming unit (CFU). Results: All tested irrigants with and without activation showed a significant reduction in E. faecalis count. The ultrasonic activation significantly improves the antibacterial effect of the tested irrigant. In comparison between the tested irrigants, there was a significant difference. The higher reduction in E. faecalis count was recorded with 1% NaOCl followed by 6% chitosan. The use of 6% citric acid has a lower effect among the tested irrigants. Conclusion: Activation of irrigant solution significantly improves their antibacterial effect. chitosan has a significant effect on the reduction of E. faecalis count. Citric acid cannot be used alone as an irrigant solution.

Objectives This study assessed the antibacterial activity of both separate and combined uses of 5.25% sodium hypochlorite (NaOCl), 2% chlorhexidine (CHX), 17% ethylenediaminetetraacetic acid (EDTA), 3% hydrogen peroxide (H 2 O 2 ), MTAD, SmearClear (SC) and 13.8% chlorine dioxide (ClO 2 ) irrigation solutions against Enterococcus faecalis. Materials and Methods Two hundred eighty single rooted human premolars were randomly grouped into 26 test and 2 control (negative and positive) groups and were incubated for 24 h with E. faecalis , except for the negative control group. The tested solutions were as follow: NaOCl; CHX; ClO 2 ; MTAD; SC; EDTA; H 2 O 2 ; NaOCl + CHX; NaOCl + MTAD; SC + NaOCl; EDTA + NaOCl; H 2 O 2 + NaOCl; ClO 2 + CHX; CHX + MTAD; SC + CHX; EDTA + CHX; CHX + H 2 O 2 ; ClO 2 + MTAD; SC + ClO 2 ; EDTA + ClO 2 ; ClO 2 + H 2 O 2 ; SC+MTAD; EDTA+MTAD; MTAD + H 2 O 2 ; SC + H 2 O 2; and EDTA + H 2 O 2. Optic density values were recorded at 0, 6, 12, 18, 24, 30, 36, 42 and 48 h and bacterial growth curve created for each solution. Results The CHX, MTAD and ClO 2 showed a high potential for the elimination of E. faecalis, both alone and in all combinations. The EDTA, H 2 O 2 , H 2 O 2 + EDTA, H 2 O 2 + NaOCl and SC + NaOCl groups showed less antibacterial activity than the other groups. The SC + CHX group showed the best antibacterial effect against E. faecalis . Conclusion The SC + CHX combination can be recommended as the most effective irrigation regimen against E. faecalis in persistent endodontic infections.
