Pauletto G, Guerim PHF, Barbosa AB, Lopes LQS, Bier CAS, Marquezan PK. Efficacy of calcium hypochlorite in disinfection of gutta-percha cones contaminated with Candida albicans. Braz J Microbiol 2024; 55:403-410. [PMID: 38225531 PMCID: PMC10920541 DOI: 10.1007/s42770-024-01255-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Accepted: 01/08/2024] [Indexed: 01/17/2024] Open
Abstract
This study aimed to compare the efficacy of 2.5% sodium hypochlorite (NaOCl), 2.5% calcium hypochlorite [Ca(OCl)2], and 2% chlorhexidine (CHX) in the rapid disinfection of gutta-percha cones contaminated with Candida albicans. The minimum inhibitory and minimum fungicidal concentrations of each solution for C. albicans were determined and the ability of each solution to destroy and inhibit biofilm in culture wells was tested. In addition, ninety-eight gutta-percha cones contaminated with the fungal suspension were disinfected according to the type of solution (2.5% NaOCl, 2.5% Ca(OCl)2 or 2% CHX) in its different application methods (without agitation, ultrasonic agitation or agitation with Easy Clean), and regarding the exposure time to each irrigating solution (1 or 5 min). Next, the samples were checked for turbidity and evaluation of viable colonies. The compounds that showed the best performance in biofilm destruction were NaOCl and Ca(OCl)2 at a concentration of 2xMIC (p < 0.001). Regarding inhibited biofilm, the only compound that was effective at all MIC concentrations tested was 2.5% Ca(OCl)2 (p < 0.0001). Regarding the viable colonies, all solutions were effective concerning the control group, for all application methods, in 1 and 5 min (p < 0.05). The densitometer reading showed that CHX was the only effective solution in all application methods performed (p < 0.05). The results demonstrate that all tested solutions were effective in the rapid decontamination of cones contaminated with C. albicans.

A Local Desiccant Antimicrobial Agent as an Alternative to Adjunctive Antibiotics in the Treatment of Periodontitis: A Narrative Review. Antibiotics (Basel) 2023; 12:antibiotics12030456. [PMID: 36978324 PMCID: PMC10044681 DOI: 10.3390/antibiotics12030456] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Revised: 02/20/2023] [Accepted: 02/22/2023] [Indexed: 03/03/2023] Open
Abstract
Periodontitis is one of the most common oral polymicrobial infectious diseases induced by the complex interplay between the altered subgingival microbiota and the host’s dysregulated immune-inflammatory response, leading to the initiation of progressive and irreversible destruction of the periodontal tissues and eventually to tooth loss. The main goal of cause-related periodontal therapy is to eliminate the dysbiotic subgingival biofilm in order to arrest local inflammation and further periodontal tissue breakdown. Because, in some cases, subgingival mechanical instrumentation has limited efficiency in achieving those goals, various adjunctive therapies, mainly systemic and locally delivered antimicrobials, have been proposed to augment its effectiveness. However, most adjunctive antimicrobials carry side effects; therefore, their administration should be precociously considered. HybenX® (HY) is a commercial therapeutical agent with decontamination properties, which has been studied for its effects in treating various oral pathological conditions, including periodontitis. This review covers the current evidence regarding the treatment outcomes and limitations of conventional periodontal therapies and provides information based on the available experimental and clinical studies related to the HY mechanism of action and effects following its use associated with subgingival instrumentation and other types of dental treatments.

[PMID: 36820402 PMCID: PMC9938646 DOI: 10.2147/ccide.s399756] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Accepted: 02/02/2023] [Indexed: 02/16/2023] Open
Abstract
Purpose With the demand for better efficiency during endodontic therapy, the purpose of this in vitro study was to evaluate the efficiency of ethyl acetate (EthOAc) extract of Matricaria chamomilla (L.) against Enterococcus faecalis and compare with standard root canal irrigation solutions. Material and Methods The antibacterial effect against Enterococcus faecalis of the EthOAc extract of Matricaria chamomilla was assessed without, or with dentine powder, using agar disk diffusion method. The inhibition zones induced by the EthOAc extract were observed after 5 minutes, 60 minutes, and 24 hours and compared with standard irrigation solutions (2% chlorhexidine and 2% sodium hypochlorite) without, or after mixing with dentine powder. Statistical analysis of the results were analysed with the Kruskal-Wallis test and one-way ANOVA. Results There was no inhibition zone in samples with and without dentine powder after combination of ethyl acetate extract of Matricaria chamomilla with sodium hypochlorite. When the extract was used alone in samples without dentine powder, the inhibition zone was 9.7 mm after 24 h, but this zone was decreased after adding dentine powder (7.7 mm). When the extract was used in combination with CHX, the inhibition zone in samples with dentine powder was 25.3 mm, but it was decreased after adding dentine powder (21.7 mm). Conclusion The EthOAc extract of Matricaria chamomilla as alternative root canal irrigant may be a useful natural agent with antibacterial activity against Enterococcus faecalis. Also, it showed promising results in endodontic therapy after combination with chlorhexidine in Enterococcus faecalis eradication.

Cytotoxic Effects on Gingival Mesenchymal Stromal Cells and Root Surface Modifications Induced by Some Local Antimicrobial Products Used in Periodontitis Treatment. MATERIALS 2021; 14:ma14175049. [PMID: 34501140 PMCID: PMC8434495 DOI: 10.3390/ma14175049] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/22/2021] [Revised: 08/30/2021] [Accepted: 08/31/2021] [Indexed: 12/12/2022]
Abstract
(1) Background: this study aims to test the cytotoxicity of three antimicrobial products used in periodontitis treatment on gingival mesenchymal stem cells (gMSCs) and their influence on root surfaces and gMSC adhesion. We tested the null hypothesis that the effects of the antimicrobials did not differ. (2) Methods: the commercial products based on sulphonic/sulphuric acids, sodium hypochlorite and silver nanoparticles, in five different concentrations, were added to culture medium for growing gMSCs. Cell proliferation capacity was tested using the Cell Counting Kit-8 (CCK8) and their viability was determined by succinate dehydrogenase activity (MTT) assay. Scanning electron microscopy evaluated the adhesion of gMSCs on root samples treated mechanically and with commercial products. (3) Results: the products induced a dose-dependent cytotoxicity in terms of reduced proliferation and viability of gMSCs, as well as cell shape modifications. Significant differences in CCK8 values between the different commercial products were observed. Based on proliferation tests, the null hypothesis was rejected. When MTT values of the three products were compared with each other, no significant differences were observed for any of the five concentrations (p = 0.065, p = 0.067, p = 0.172, p = 0.256, p = 0.060). (4) Conclusions: the three antimicrobials had a certain degree of cytotoxicity on gMSCs. gMSCs repopulated treated root surfaces.
