Abstract
INTRODUCTION Safe practice in medicine and dentistry has been a global priority area in which large knowledge gaps are present.Patient safety strategies aim at preventing unintended damage to patients that can be caused by healthcare practitioners. One of the components of patient safety is safe clinical practice. Patient safety efforts will help in ensuring safe dental practice for early detection and limiting non-preventable errors.A valid and reliable instrument is required to assess the knowledge of dental students regarding patient safety. OBJECTIVE To determine the psychometric properties of a written test to assess safe dental practice in undergraduate dental students. MATERIAL AND METHODS A test comprising 42 multiple-choice questions of one-best type was administered to final year students (52) of a private dental college. Items were developed according to National Board of Medical Examiners item writing guidelines. The content of the test was determined in consultation with dental experts (either professor or associate professor). These experts had to assess each item on the test for language clarity as A: clear, B: ambiguous and relevance as 1: essential, 2: useful, not necessary, 3: not essential. Ethical approval was taken from the concerned dental college. Statistical analysis was done in SPSS V.25 in which descriptive analysis, item analysis and Cronbach's alpha were measured. RESULT The test scores had a reliability (calculated by Cronbach's alpha) of 0.722 before and 0.855 after removing 15 items. CONCLUSION A reliable and valid test was developed which will help to assess the knowledge of dental students regarding safe dental practice. This can guide medical educationist to develop or improve patient safety curriculum to ensure safe dental practice.

Abstract
OBJECTIVE This study aimed to evaluate the in vitro antibacterial effects of lysozyme-chitosan oligosaccharide conjugates (LYZOX) against Streptococcus gordonii and Porphyromonas gingivalis. MATERIALS AND METHODS Planktonic S. gordonii and P. gingivalis were treated with various concentrations of LYZOX for 10 min. The treated bacteria were incubated on trypticase soy agar plates, and colony-forming unit (CFU) was calculated. The antibacterial effect of LYZOX was compared with that of lysozyme, chitosan, physiological saline, and benzalkonium chloride solution. Cell morphology before and after LYZOX treatment was observed using a scanning electron microscope (SEM). The antibacterial effect of LYZOX with decanoic acid against the biofilm-like bacteria was also examined via crystal violet staining. The Kruskal-Wallis test and post hoc Dunn tests were performed to compare the difference in antibacterial activity of each treatment. RESULTS Bacterial CFU numbers were reduced after LYZOX treatment in a concentration-dependent manner. The reduction in CFUs was smaller for corresponding concentrations of chitosan or lysozyme alone. SEM analyses revealed bacterial cells shrank following LYZOX treatment. The combined use of LYZOX and decanoic acid yielded an even higher antibacterial effect against bacterial biofilms. CONCLUSION LYZOX exhibits antibacterial activity against two periodontal bacteria and may be a promising plaque control agent.

Abstract
BACKGROUND Gingival inflammation, a hallmark of periodontal diseases, serves as a critical focus in oral health research. Characterized by redness, swelling, and bleeding of the gingival tissues, it reflects the body's response to bacterial biofilms accumulating on the tooth surfaces. This inflammatory process, initiated by the interaction between oral bacteria and the host immune system, can lead to a spectrum of periodontal conditions ranging from mild gingivitis to severe periodontitis. Understanding the efficacy of various methods to treat gingival inflammation is essential for refining treatment strategies and enhancing patient satisfaction in the realm of gingival inflammation. AIM The objective of the study was to evaluate the efficacy of employing the microneedling technique with olive oil on gingival inflammation and plaque accumulation in individuals with gingivitis. Materials and methods:Twenty-four individuals diagnosed with plaque-induced gingivitis were selected from Saveetha Dental College, Chennai. Participants were randomly assigned to one of two groups: Group A, comprising 12 individuals who received mechanical periodontal treatment only and Group B, consisting of 12 individuals treated with dermapen and topical olive oil. This involved the creation of microholes in the gingival tissue to enhance the concentration and penetration of the oils through the gingival tissues. Post-intervention assessments of gingival and plaque status were conducted using a gingival index and a plaque index at baseline, one, two, and four weeks. Statistical analysis was done using IBM SPSS Statistics for Windows, version 23 (IBM Corp., Armonk, NY, USA). Intergroup analysis was done using Mann-Whitney test and intra-group analysis was done using Kruskal-Wallis test for all the study parameters. Statistical significance was set at a p-value of less than 0.05. RESULTS The mean plaque index scores were 2.02 ± 0.12 and 2.29 ± 0.21 in the subgingival scaling and microneedling with olive oil group respectively in baseline. The scores were 1.83 ± 0.29 and 0.57 ± 0.16 in the subgingival scaling and microneedling with olive oil group respectively at the end of four weeks. The results of plaque index scores were statistically significant between the control and the intervened groups at the end of four weeks with a p value of 0.01*. The mean gingival index scores were 2.09 ± 0.16 and 2.37 ± 0.17 in the subgingival scaling and microneedling with olive oil group in the baseline respectively. The scores were 1.88 ± 0.23 and 0.96 ± 0.21 in the subgingival scaling and microneedling with olive oil group respectively at the end of four weeks. The results of gingival index scores were statistically significant between the control and the intervened groups at the end of four weeks with a p value of 0.01*. CONCLUSION Our research showcased a novel and effective technique, unveiling a significant enhancement in gingival health accompanied by a reduction in both the average gingival index and plaque index.

Abstract
OBJECTIVES The objective of this scoping review was to map evidence of electrolysed oxidising water (EOW) as a biocide for dental applications of relevance to older people and identify research gaps. BACKGROUND EOW is an emerging, "green," and cost-effective biocide. There are no reviews on the landscape of EOW research as either an antiseptic or disinfectant in dental healthcare or its suitability for the oral healthcare of older people. MATERIALS AND METHODS The review follows the PRISMA Extension for Scoping Reviews (PRISMA-ScR) guidelines. Database searches (Google Scholar, PubMed, Web of Science, Ovid, Scopus and Science Direct) were undertaken using MESH terms and Boolean operators with no date restrictions, to identify full-text, original reports published in English-language peer-reviewed journals. RESULTS The search yielded 114 papers that met the inclusion/exclusion criteria. Dental applications of EOW include its use as an endodontic irrigant (39%); mouth rinse/surgical irrigant (21%); disinfectant for dental unit water lines (19%) and dental biomaterials (17%); and for antimicrobial efficacy, effects on oral tissues and on dental material properties. Most studies (83%) evaluated a single EOW formulation (acidic, moderately acidic or neutral) that was either generated at 'point-of-use' (POU; 72%), bottled ('ready-to-use', RTU; 24%) or from unspecified (3%) sources. Six reports evaluated storage-related parameters and 25 evaluated clinical applications; 89 were in vitro studies and one investigated the cost-effectiveness of POU EOW. CONCLUSIONS Neutral-pH, EOW is effective as an antimicrobial agent without deleterious effects on oral tissues. However, research on the impact of storage conditions, anti-Candida biofilm efficacy and mechanism of action against yeasts, long-term effects on denture materials and cost-effectiveness is required to establish the suitability of EOW as a multipurpose biocide for dental healthcare, including infection-control requirements relating to older people.

Disinfection and Isotonic Drinks' Influence on Hardness and Color Stability of Ethylene-Vinyl-Acetate Copolymer Mouthguards Used in Martial Arts: An In Vitro Study. Polymers (Basel) 2023; 15:polym15081822. [PMID: 37111969 PMCID: PMC10146693 DOI: 10.3390/polym15081822] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2023] [Revised: 03/19/2023] [Accepted: 04/07/2023] [Indexed: 04/29/2023] Open
Abstract
This in vitro study aimed to evaluate the hardness and color change of an ethylene-vinyl-acetate copolymer (EVA) material for mouthguards after exposition to different cleaning agent solutions and isotonic drinks. Four hundred samples were prepared and divided into four equinumerous groups (n = 100), in which there were 25 samples from each color of EVA (red, green, blue and white). The hardness, using the digital durometer, and the color coordinates (CIE L*a*b*), using the digital colorimeter, were measured before the first exposition and after 3 months of exposition to spray disinfection and incubation in the oral cavity temperature, or immersion in isotonic drinks. The values of Shore A hardness (HA) and color change (ΔE-calculated by Euclidean distance) were statistically analyzed using the Kolmogorov-Smirnov test, multiple comparison ANOVA/Kruskal-Wallis and appropriate post-hoc tests. Statistically significant changes in color and hardness between the tested groups were demonstrated after the use of agents predestined for disinfecting the surface of mouthguards on the tested samples. There were no statistically significant differences in color and hardness between the groups immersed in isotonic sport drinks potentially consumed by competitors practicing combat sports using mouthguards. Despite the changes in color and hardness after the use of disinfectants, the deviations were minor and limited to specific colors of the EVA plates. The intake of isotonic drinks practically did not change either the color or the hardness of the samples, regardless of the tested color of the EVA plates.

Abstract
OBJECTIVE The aim of this research was to assess the effect of 0.12% chlorhexidine (CHX) and a Salvadora persica-based mouthwash on whole salivary tumour necrosis factor-alpha (TNF-α) levels and periodontal inflammation in patients with type 2 diabetes mellitus (T2DM). METHODS Patients with and without medically diagnosed T2DM were included. Patients' medical records were evaluated to confirm the diagnosis of T2DM. All patients underwent nonsurgical periodontal therapy (NSPT). Patients were divided into 2 subgroups. In the test and control group, patients were advised to rinse with an S persica-based mouthwash and a non-alcoholic 0.12% CHX after NSPT twice daily for 2 weeks, respectively. Demographic data were collected. Full-mouth plaque index (PI), gingival index (GI), probing depth (PD), and clinical attachment loss (AL) were measured, and whole salivary TNF-α levels were gauged at baseline and at 3-month follow-up. Haemoglobin A1c (HbA1c) levels were measured in all patients at baseline and at 3-month follow-up. Sample size estimation was done, and group comparison was performed. Level of significance was set at P < .01. RESULTS Twenty-one nondiabetic individuals and 21 patients with T2DM were included. At baseline, there was no significant difference in clinical and radiographic periodontal parameters amongst in patients with and without T2DM. At 3-month follow-up, HbA1c, TNF-α, PI, PD, and clinical AL were comparable with their respective baseline values in the test and control groups amongst patients with T2DM. In nondiabetic individuals, there was a significant reduction in PI (P < .01), GI (P < .01), and PD (P < .01), and TNF-α (P < .01) at 3-month follow-up in the test and control groups compared with their respective baseline scores. CONCLUSIONS In the short term, NSPT with 0.12% CHX or S persica-based mouthwashes is more effective in reducing periodontal inflammation and whole salivary TNF-α levels in nondiabetic individuals than in patients with T2DM with periodontal inflammation.

Abstract
Introduction: Plaque biofilms, mainly formed by Streptococcus mutans (S. mutans), play an important role in the occurrence and development of dental caries. Antibiotic treatment is the traditional way to control plaque. However, problems such as poor drug penetration and antibiotic resistance have encouraged the search for alternative strategies. In this paper, we hope to avoid antibiotic resistance through the antibacterial effect of curcumin, a natural plant extract with photodynamic effects, on S. mutans. However, the clinical application of curcumin is limited due to its low water solubility, poor stability, high metabolic rate, fast clearance rate, and limited bioavailability. In recent years, liposomes have become a widely used drug carrier due to their numerous advantages, such as high drug loading efficiency, high stability in the biological environment, controlled release, biocompatibility, non-toxic, and biodegradability. So, we constructed a curcumin-loaded liposome (Cur@LP) to avoid the defect of curcumin.Methods: Cur@LP functioned with NHS can adhere to the surface of the S. mutans biofilm by condensation reaction. Liposome (LP) and Cur@LP was characterized by transmission electron microscopy (TEM) and dynamic light scattering (DLS). The cytotoxicity of Cur@LP was evaluated by CCK-8 assay and LDH assay. The adhesion of Cur@LP to S. mutans biofilm was observed by confocal laser scanning microscope (CLSM). The antibiofilm efficiency of Cur@LP were evaluated by crystal violet staining, CLSM, and scanning electron microscope (SEM).Results: The mean diameter of LP and Cur@LP were 206.67 ± 8.38 nm and 312 ± 18.78 nm respectively. The ζ-potential of LP and Cur@LP were ∼−19.3 mV and ∼−20.8 mV respectively. The encapsulation efficiency of Cur@LP was (42.61 ± 2.19) %, and curcumin was rapidly released up to ±21% at 2 h. Cur@LP has negligible cytotoxicity, and can effectively adhered to the S. mutans biofilm and inhibited its growth.Discussion: Curcumin has been widely studied in many fields such as cancer, which can be attributed to its antioxidant and anti-inflammatory effects. At present, there are few studies on the delivery of curcumin to S. mutans biofilm. In this study, we verified the adhesion and antibiofilm of Cur@LP to S. mutans biofilm. This biofilm removal strategy has the potential to be translated into the clinic.

Abstract
There is increased interest in outcome measures that complement the classic goal of endodontics, being the prevention and healing of apical periodontitis. Possible outcome measures can be subdivided into patient-centred outcomes (PCOs), encompassing data collected by nonpatients aiming to assess the effectiveness of an intervention and patient-reported outcomes (PROs), which are reported directly by the patient. PROs can be subsequently classed into PRO measures that ascertain patients' view of their symptoms, their functional status, and their health-related quality of life, and patient-reported experience measures that focus on aspects including the humanity of care, patient satisfaction, patient preference and adherence, personal costs, expectation fulfilment, and decision regrets. The present review aims to define various patient-related outcomes and discuss the literature available regarding PCOs and PROs in endodontics. This includes those proposed to assess the effectiveness of endodontic treatment for pulpitis and apical periodontitis for use in the development of European Society of Endodontology S3-level clinical practice guidelines that have been included by all working groups, except for the radiographic assessment of apical periodontitis. Based on limited evidence in the field, it can be summarized that after recall periods of various lengths, endodontic treatment is associated with a high likelihood of tooth survival and limited need for further intervention, including extraction and further restorative procedures. Oral Health-Related Quality of Life (OHRQoL) is likely to improve following the completion of treatment. Nonetheless, the literature assessing the association between OHRQoL and endodontics is hampered by the use of instruments that have not been previously validated. Amongst the remaining outcome measures discussed in the present review, it is worth highlighting that there is only one study assessing exacerbations in teeth with the presence of endodontic pathosis, which suggests a very low incidence of this adverse effect following endodontic treatment. Patients' expectation fulfilment, adherence, and satisfaction are closely inter-related and depend also on various nonclinical factors. Further studies assessing PCOs and PROs, in association with healing and prevention of apical periodontitis, are required to better understand endodontic treatment from the perspective of patients.

[PMID: 36914302 DOI: 10.1016/j.jebdp.2022.101805] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2022] [Revised: 09/11/2022] [Accepted: 10/29/2022] [Indexed: 11/16/2022]
Abstract
Recently in oral health care settings, the focus of assessing treatment outcomes has shifted from the perspective of the clinician towards that of the patient. Endodontology is a specialty of dentistry concerned with the prevention and treatment of pulp and periapical diseases. Research in endodontology and its associated treatment outcomes have focused mainly on clinician-reported outcomes (CROs) and not dental patient-reported outcomes (dPROs). As a result, there is a need to emphasize the importance and relevance of dPROs to researchers and clinicians. The aim of this review is to present an overview of dPROs and dPROMs within endodontics in an attempt to create a better understanding of the patient experience, highlight the need to place the patient at the center of treatment, enhance patient care and encourage more research into dPROs. The key dPROs following endodontic treatment include pain, tenderness, tooth function, need for further intervention, adverse effects (exacerbation of symptoms, tooth discoloration) and Oral Health-Related Quality of Life. dPROs are important following endodontic treatment because they assist clinicians and patients when they discuss and select the most appropriate management options, help clinicians make decisions on pre-operative assessment, prevention and treatment, and improve the methodology and design of future clinical studies. Clinicians and researchers in endodontology should prioritize patient welfare and undertake routine analyses of dPROs using appropriate and robust measures. Due to the lack of agreement over the reporting and definition of endodontic treatment outcomes, a comprehensive project to define a ``Core Outcome Set for Endodontic Treatment Methods (COSET)'' is currently ongoing. In the future, a new and exclusive assessment tool should be developed to reflect the viewpoints of patients receiving endodontic treatment more accurately.

Comparison of the postoperative anti-inflammatory efficacy of chlorhexidine, saline rinses and herbal mouthwashes after mechanical debridement in patients with peri-implant mucositis: A randomized controlled trial. Int J Dent Hyg 2023; 21:203-210. [PMID: 35090087 DOI: 10.1111/idh.12582] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2021] [Revised: 01/10/2022] [Accepted: 01/21/2022] [Indexed: 01/12/2023]
Abstract
AIM The null hypothesis is that there is no difference in the post-operative anti-inflammatory efficacy of chlorhexidine (CHX), 2% saline rinses (SR) and a herbal mouthwash (MW) after non-surgical mechanical debridement (MD) for treatment of peri-implant mucositis (PiM). The aim was to compare the post-operative anti-inflammatory efficacy of CHX, 2% SR and a herbal oral rinse after non-surgical MD of PiM. MATERIALS AND METHODS The present randomized controlled trial had a single-blinded parallel arm design. Patients diagnosed with PiM were enrolled. Demographic information was recorded. All patients underwent MD and were randomly divided into 4 groups: CHX-group: 0.12% non-alcoholic CHX; Sodium chloride (NaCl) group: 2% NaCl rinses; Herbal MW group: Herbal-based MW and H2 O group: distilled water with peppermint flavour. After MD, all the participants were advised to rinse twice daily (every 12 hrs) for 2 weeks with their respective MWs. In all groups, peri-implant modified plaque index (mPI), modified gingival index (mGI) and probing depth (PD) were measured at baseline and at 12 weeks of follow-up. Sample size was estimated using data from a pilot investigation; and group-comparisons were performed. Statistical significance was confirmed when P-values were below 0.01. RESULTS Sixty individuals (15 patients/group) were included. At baseline, mPI, mGI and PD were comparable in all groups. At baseline, there was no significant difference in peri-implant mPI, mGI and PD in all groups. At 12-weeks' follow-up, there was a statistically significant reduction in peri-implant mPI (p < 0.01), mGI (p < 0.01) and PD (p < 0.01) in CHX, NaCl and herbal MW groups compared with H2 O group. There was no significant relation between implant location, duration for which, implants were functional, gender and peri-implant clinical parameters in all groups. CONCLUSION After non-surgical MD, post-operative use of CHX and herbal and NaCl MWs is useful for the management of PiM in the short-term.

Abstract
Following surgery, healing within the oral cavity occurs in a hostile environment, and proper oral care and hygiene are required to accelerate recovery. The aim of the current study is to investigate and compare the bioreactivity characteristics of mouthwashes based on either chlorhexidine (CHX) or a novel bone bioactive liquid (BBL) in terms of oral healing within seven days application post-surgery. A randomized, double blind clinical trial was conducted in 81 patients, wherein the mouthwashes were applied twice a day for a period of 7 days. The visual analog scale (VAS) protocol was applied to determine pain index scores. Early wound healing index (EHI) score was determined for evaluating oral cavity healing progress. No adverse effects were observed using the mouthwashes, but CHX application resulted in stained teeth. Applications of both CHX and BBL were sufficient to reduce pain over a period of 7 days. However, the BBL group demonstrated a statistically significant reduction in VAS scores starting on day 4. The EHI scores were significantly higher in the BBL group compared with the CHX group, independent of tooth location. No differences in either VAS or EHI scores due to gender were observed. Compared with the commercially available CHX mouthwash, application of the BBL mouthwash reduced pain and accelerated oral cavity healing to a greater extent, suggesting it effectively improves the oral cavity microenvironment at the wound site in mediating soft tissue regeneration.

J Funct Biomater 2022; 13:jfb13040175. [PMID: 36278644 PMCID: PMC9589978 DOI: 10.3390/jfb13040175] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2022] [Revised: 09/29/2022] [Accepted: 09/30/2022] [Indexed: 01/10/2023] Open
Abstract
Numerous epithelial cells and sometimes leukocytes release AMPs as their first line of defense. AMPs encompass cationic histatins, defensins, and cathelicidin to encounter oral pathogens with minimal resistance. However, their concentrations are significantly below the effective levels and AMPs are unstable under physiological conditions due to proteolysis, acid hydrolysis, and salt effects. In parallel to a search for more effective AMPs from natural sources, considerable efforts have focused on synthetic stable and low-cytotoxicy AMPs with significant activities against microorganisms. Using natural AMP templates, various attempts have been used to synthesize sAMPs with different charges, hydrophobicity, chain length, amino acid sequence, and amphipathicity. Thus far, sAMPs have been designed to target Streptococcus mutans and other common oral pathogens. Apart from sAMPs with antifungal activities against Candida albicans, future endeavors should focus on sAMPs with capabilities to promote remineralization and antibacterial adhesion. Delivery systems using nanomaterials and biomolecules are promising to stabilize, reduce cytotoxicity, and improve the antimicrobial activities of AMPs against oral pathogens. Nanostructured AMPs will soon become a viable alternative to antibiotics due to their antimicrobial mechanisms, broad-spectrum antimicrobial activity, low drug residue, and ease of synthesis and modification.

Abstract
Objectives In our research, we evaluated the effect of coconut and sesame oils using the microneedling technique on gingival inflammation and plaque accumulation among patients with gingivitis by creating microholes in the gingiva to facilitate the concentration and entrance of the oils through gingival tissues. Materials and Methods Twenty‐four patients with clinically diagnosed plaque‐induced gingivitis were selected from Vision dental hospital, Riyadh, KSA, and assigned to one of three groups randomly; group A consisted of eight participants who were treated with dermapen and topical coconut oil, group B had eight participants who were treated with dermapen and topical sesame oil, and group C involved eight patients who received periodontal mechanical treatment only. Postintervention gingival status and plaque status for all participants were assessed using a modified average gingival index and a plaque index at Weeks 1, 2, and 4. Results Groups A and B experienced highly significant reductions in gingival indices, while group C showed reduced scores but was not significantly notable. On the contrary, the three studied groups exhibited no significant difference in the reduction of plaque indices when compared altogether. Conclusion Our study demonstrated an effective novel technique that revealed a noticeable improvement in gingival status and a reduction in the average gingival index and plaque index.

Abstract
The aim was to compare the in-vitro antibacterial effectiveness of two herbal extracts (a) Saussurea-costus (S. costus) and (b) Melaleuca-alternifolia (M. alternifolia) against Porphyromonas gingivalis (P. gingivalis), Streptococcus mutans (S. mutans) and Enterococcus faecalis (E. faecalis). Aqueous extracts from M. alternifolia were prepared by adding 2 grams of S. costus and M. alternifolia, respectively to 100 ml distilled water. Bacterial strains of P. gingivalis, E. faecalis and S. mutans were treated into 3 groups. In groups 1 and 2, bacterial strains were treated with aqueous extracts of S. costus and M. alternifolia, respectively. In the control-group, bacterial strains were exposed to distilled water. Antibacterial activity of the samples and nanoparticles was determined. The minimum-inhibitory-concentration (MIC) values were determined using the microdilution method. P < 0.01 was considered statistically significant. The MIC for all bacterial strains treated with S. costus was significantly higher than that of M. alternifolia (P < 0.001). There was no significant difference in MIC for strains of P. gingivalis, E. faecalis and S. mutans treated with S. costus. For bacterial strains treated with M. alternifolia, the MIC was significantly higher for P. gingivalis compared with E. faecalis and S. mutans strains (P < 0.01). There was no difference in MIC for E. faecalis and S. mutans strains treated with M. alternifolia. The in-vitro antibacterial efficacy of M. alternifolia is higher than S. costus against P. gingivalis, E. faecalis and S. mutans.

Abstract
Chlorhexidine has been one of the most effective and popular antiseptic substances used in medicine for decades. In dentistry, it has been used in endodontics, periodontology, surgery, and general dentistry. It is also widely used daily by patients in mouth rinses, gels, or toothpastes. Because of its multiple uses, we should follow all types of research reporting its potential adverse effects. This article aims to review the most up-to-date studies regarding chlorhexidine and its possible side effects, in the period of the SARS-CoV-2 pandemic, as the use of different antiseptic substances has rapidly increased.

Abstract
Objectives The aim of this work was to review the current uses of chlorhexidine (CHX) in dentistry based on its mechanism of action, whilst highlighting the most effective protocols that render the highest clinical efficacy whilst limiting adverse drug reactions. Methods A literature search was conducted using the key words chlorhexidine, mechanism of action, adverse effects, and dentistry using databases in the University of Toronto library system. The titles and abstracts were read, and relevant articles were selected. Results A total of 1100 publications were identified, 100 were investigated, and 67 of them were used. Out of the 67 selected articles, 12 were reviews on CHX; 5 articles focussed on CHX gels; 13 focussed on CHX mouthwashes; 8 focussed on CHX products; 13 discussed adverse effects associated with CHX; 13 focussed on periodontal pathology and treatment; 6 focussed on implant periodontal and dental surgeries; 7 evaluated effects on caries; 6 looked at the mechanisms of action; and 12 focussed on the antibacterial and antimicrobial impact on the oral biome. There were multiple areas of overlap amongst the articles, and results showed that CHX provides different uses, but mainly as an adjunct to various treatments. Mouthwash was the most superior medium when used in short time spans when mechanical prophylaxis was not possible for the prevention of gingivitis and maintenance of oral hygiene. CHX products are often used in periodontics, post–oral surgical procedures, and as a prophylaxis for multiple invasive procedures with minimal adverse effects. Tooth staining was the most negative adverse effect reported by patients. Conclusions CHX's antimicrobial properties make it an ideal prophylactic when mechanical debridement is not possible. CHX mouthwash appears to be more effective compared to gels. Concentrations of 0.12% to 0.2% are recommended; any mouthwash with concentrations above 0.2% will unnecessarily increase the unwanted side effects. CHX is useful amongst various areas of dentistry including oral surgery, periodontics, and even general dentistry. For long-term treatments, especially in periodontitis patients (stage I-III) undergoing nonsurgical treatments, CHX chips are recommended. CHX chips are also recommended as an adjunct to implant debridement in patients with peri-implant mucositis and peri-implantitis over CHX mouthwash and gels.

Abstract
AIM The present randomized controlled trial assessed the postoperative anti-inflammatory efficacy of 2% saline rinses (SR) and a herbal- mouthwash (HMW) after non-surgical periodontal therapy (NSPT) for the management of periodontal inflammation in patients with chlorhexidine (CHX) allergy. MATERIALS AND METHODS Patients with periodontal inflammation with and without self-reported CHX-allergy were included. All patients underwent non-surgical periodontal therapy (NSPT). Patients were randomly divided into three groups. In the SR and HMW groups, 2% SR, and a HMW, respectively were prescribed. In Group-3 (CHX-group), patients without CHX allergy were included and were prescribed 0.12% CHX. In all groups, plaque index (PI), gingival index (GI), probing depth (PD), clinical attachment loss (AL) and marginal bone loss were measured at baseline. Clinical periodontal parameters were re-assessed at 6-weeks' follow-up. P<0.01 were considered statistically significant. RESULTS Thirteen, 12 and 12 patients were included in the SR, HMW and CHX groups, respectively. At baseline clinical and radiographic periodontal parameters were comparable in all groups. In all groups, PI (P<0.01), GI (P<0.01) and PD (P<0.01) were significantly higher at baseline compared with their respective values at 6-weeks of follow-up. There was no significant difference in clinical AL at all time intervals in all groups. There was no significant correlation between periodontal parameters and age, gender and daily toothbrushing/flossing in all groups. CONCLUSION In young adults with self-reported CHX-allergy, herbal-mouthwashes and/or 2% SR are suitable postoperative prescriptions after NSPT.

Abstract
Coronavirus disease 2019 (COVID-19) is the leading pandemic facing the world in 2019/2020; it is caused by a novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, which necessitates clear understanding of the infectious agent. The virus manifests aggressive behavior with severe clinical presentation and high mortality rate, especially among the elderly and patients living with chronic diseases. In the recent years, the role of gut microbiota, in health and disease, has been progressively studied and highlighted. It is through gut microbiota-organ bidirectional pathways, such as gut-brain axis, gut-liver axis, and gut-lung axis, that the role of gut microbiota in prompting lung disease, among other diseases, has been proposed and accepted. It is also known that respiratory viral infections, such as COVID-19, induce alterations in the gut microbiota, which can influence immunity. Based on the fact that gut microbiota diversity is decreased in old age and in patients with certain chronic diseases, which constitute two of the primary fatality groups in COVID-19 infections, it can be assumed that the gut microbiota may play a role in COVID-19 pathology and fatality rate. Improving gut microbiota diversity through personalized nutrition and supplementation with prebiotics/probiotics will mend the immunity of the body and hence could be one of the prophylactic strategies by which the impact of COVID-19 can be minimized in the elderly and immunocompromised patients. In this chapter, the role of dysbiosis in COVID-19 will be clarified and the possibility of using co-supplementation of personalized prebiotics/probiotics with current therapies will be discussed.

Abstract
Periodontal diseases are one of the most significant challenges in dental health. It is estimated that only a few percent of the worldwide population have entirely healthy teeth, and according to WHO, oral diseases may affect up to 3.5 billion people worldwide. One of the most serious oral diseases is periodontitis, an inflammatory disease affecting periodontal tissues, caused by pathogenic bacteria and environmental factors such as the ageing population, abuse of tobacco products, and lack of adequate oral hygiene due low public awareness. Plant materials are widely and successfully used in the management of many conditions, including periodontitis. Plant materials for periodontitis exhibit antibacterial, anti-inflammatory, antioxidant activities and affect the periodontium structure. Numerous studies demonstrate the advantages of phytotherapy for periodontitis relief and indicate the usefulness of Baikal skullcap root, Pomegranate fruit peel and root cortex, Tea leaves, Chamomile flowers, Magnolia bark, Blackberry leaves and fruits, Cranberry fruits and Lippia sidoides essential oil. This review aims to analyze the use and applicability of selected plant materials in periodontitis management since it is of paramount importance to evaluate the evidence of the traditionally used plant materials in light of continuously growing interest in phytotherapy and its adjuvant role in the treatment of periodontitis.

[PMID: 34902217 DOI: 10.1111/idh.12567] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Revised: 08/31/2021] [Accepted: 12/09/2021] [Indexed: 12/01/2022]
Abstract
BACKGROUND AND OBJECTIVE The review aims to fill the gap in literature by comparing the efficacy of herbal and chlorhexidine-based mouthwashes towards oral hygiene maintenance (OHM) in patients undergoing fixed orthodontic treatment (OT). METHODS Indexed databases were searched electronically to include randomized controlled trials (RCTs) for data gathering. The protocol was registered in PROSPERO (CRD42020182497). Risk of bias assessment, quality of evidence investigation, and meta-analysis were performed to evaluate reported OHM related parameters at time points before and after the use of chlorhexidine (control group) and herbal mouthwashes (intervention group). With 95% confidence intervals, mean difference (MD) or standardized mean difference (SMD) were used to estimate effect size. RESULTS Out of eight RCTs, results from one RCT favored chlorhexidine and the results from a second RCT favored herbal mouthwashes. Results from three RCTs showed comparable effects for the respective investigated OHM related parameters. Chlorhexidine demonstrated higher antimicrobial efficacy against Streptococcus mutans (S.mutans) in two studies, and one RCT found comparable antimicrobial efficacies. Risk of bias was low in 4 studies, and moderate and high in two studies each. Quality of evidence was very low to moderate for the respective investigated parameters. Sub-group analysis for parameters colony forming units (CFU) {SMD (0.40) [95% CI (-0.22, 1.03)], gingival index (GI) {MD (0.06) [95% CI (-0.08, 0.20)]}, plaque index (PI) {SMD 0.22 [95% CI (-0.23, 0.67)]} before the use of chlorhexidine and herbal mouthwashes remained inconclusive. CONCLUSION The comparison between efficacy of herbal and chlorhexidine towards OHM in patients undergoing fixed OT remains debatable.

[PMID: 34625985 DOI: 10.1111/joor.13268] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2021] [Revised: 08/09/2021] [Accepted: 09/21/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND Alveolar osteitis (AO) is a poorly understood, common, painful complication following exodontia. It is sometimes managed by inappropriate prescription of antibiotics which contributes to the global threat of antimicrobial resistance. Use of intra-alveolar chlorhexidine also presents a serious risk of anaphylaxis to the patient. OBJECTIVE This scoping review aims to investigate the aetiology, prevention and management of AO and highlight the extent of inappropriate prescribing and intra-alveolar chlorhexidine use. DESIGN A scoping review was undertaken using the PRISMA guidelines. Medline, Ovid and Pubmed were searched between 2010 and 2020, from which 63 studies were selected for review that related to the aetiology, prevention or management of AO. Data were analysed for frequency of studies reporting information on risk factors for aetiology, prevention strategies and management including inappropriate management using antibiotic prescribing and intra-alveolar chlorhexidine. RESULTS Impaired immune response, surgical technique and age were identified as significant factors in the development of AO, while there is conflicting evidence regarding the effects of smoking and gender. With regard to prevention, the use of prophylactic antibiotics is not supported within the literature. Saline irrigation and eugenol pastes used preventively have been shown to be cheap and effective alternatives to chlorhexidine with no adverse effects. Hyaluronic acid and low-level laser therapies showed a significant reduction in pain and soft-tissue inflammation in the management of AO compared to Alveogyl. CONCLUSIONS Further understanding of the pathophysiology of AO is needed, in addition to large high-quality RCTs or long-term observational studies into the aetiology, prevention, and management of AO to produce up-to-date evidence-based clinical guidelines. Clinicians should also be mindful of their contribution to growing antimicrobial resistance and avoid inappropriate prescribing of antibiotics. Saline should replace chlorhexidine as the intra-alveolar irrigant of choice.

Sequential Application of Calcium Phosphate and ε-Polylysine Show Antibacterial and Dentin Tubule Occluding Effects In Vitro. Int J Mol Sci 2021; 22:ijms221910681. [PMID: 34639022 PMCID: PMC8508875 DOI: 10.3390/ijms221910681] [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: 09/13/2021] [Revised: 09/25/2021] [Accepted: 09/27/2021] [Indexed: 11/23/2022] Open
Abstract
In this study, ε-polylysine and calcium phosphate precipitation (CPP) methods were employed to induce antibacterial effects and dentin tubule occlusion. Antibacterial effects of ε-polylysine were evaluated with broth dilution assay against P. gingivalis. CPP solution from MCPM, DCPD, and TTCP was prepared. Four concentrations of ε-polylysine(ε-PL) solutions (0.125%, 0.25%, 0.5%, 1%) were prepared. Dentin discs were prepared from recently extracted human third molars. Dentin discs were incubated with P. gingivalis (ATCC 33277) bacterial suspension (ca. 105 bacteria) containing Brain Heart Infusion medium supplemented with 0.1 g/mL Vitamin K, 0.5 mg/mL hemin, 0.4 g/mL L-cysteine in anaerobic jars (37 °C) for 7 days to allow for biofilm formation. P. g–infected dentin specimens were randomly divided into four groups: CPP + 0.125% ε-PL, CPP + 0.25% ε-PL, CPP + 0.5% ε-PL, CPP + 1% ε-PL. On each dentin specimen, CPP solution was applied followed by polylysine solution with microbrush and immersed in artificial saliva. Precipitate formation, antibacterial effects, and occlusion of dentinal tubules were characterized in vitro over up to 72 h using scanning electron microscopy. ε-PL showed 34.97% to 61.19% growth inhibition levels against P. gingivalis (P. g) after 24 h of incubation. On P. g-infected dentin specimens, DCPD + 0.25% ε-PL, and DCPD + 0.5% ε-PL groups showed complete bacterial inhibition and 78.6% and 98.1% dentin tubule occlusion, respectively (p < 0.001). The longitudinal analysis on fractured dentin samples in DCPD and TTCP groups revealed deeply penetrated hydroxyapatite-like crystal formations in dentinal tubules after 72 h of incubation in artificial saliva.

Abstract
BACKGROUND Oral care using chlorhexidine has been considered useful in reducing the incidence of ventilator-associated pneumonia (VAP) in adult patients. However, no study has proved the effect of oral care in reducing the incidence of VAP in preterm infants. OBJECTIVES To investigate the efficacy of oral care using a sponge brush moistened with sterile water in reducing the bacterial load in the oral cavity and the incidence of early-onset VAP in preterm infants METHODS: The bacterial number in the oral cavity was evaluated on-site with the dielectrophoretic impedance measurement system. Bacterial numbers before and after oral care were investigated prospectively. Then, the incidence of early-onset VAP was compared retrospectively between infants who received oral care before re-intubation and those who did not. RESULTS The mean bacterial number (cfu/ml) in the oral cavity in infants managed with endotracheal intubation (n = 23), continuous positive airway pressure (n = 38), and high-flow nasal cannula (n = 22) significantly reduced (p < .01) after versus before oral care (4.46 × 107 vs. 1.25 × 106 ; 1.32 × 107 vs. 6.82 × 105 ; and 1.68 × 107 vs. 6.50 × 105 ). The incidence rate of early-onset VAP after re-intubation was 51% (20/39) in patients who did not receive oral care. Then, it significantly decreased to 21% (7/33; p = .009) after receiving oral care. CONCLUSION Oral care with sterile water may be effective in reducing the bacterial load in the oral cavity and the incidence of early-onset VAP in preterm infants.

Abstract
Objectives The current COVID‐19 pandemic highlighted the need for a review of guidelines on infection control and prevention to ensure safe delivery of dental care. However, it is not clear to what extent the rapidly published European guidelines reflect the current evidence and thus provide homogeneous recommendations. Material & Methods Guidelines from all European Union countries, Scotland, Switzerland and United Kingdom were retrieved. Information on triage, mouth rinse, personal protective equipment (PPE) for aerosol free/ generating procedures (non‐AGP/AGP) and treatment of potentially infectious patients were summarized and compared with recommendations from international organizations (WHO, ECDC, CDC). Results All included countries (30/30) published COVID‐19 guidelines in 2020. All countries recommended triage and to postpone non‐urgent treatment of potentially infectious patients. Hydrogen peroxide (1%–1.5%) was the most frequently recommended antiseptic mouth rinse to reduce viral load (24/30). PPE for non‐AGP treatments included mainly surgical masks (21/30) or FFP2/FFP3/N95 masks (16/30), whereas FFP2/FFP3 masks (25/30) and face shields (24/30) were recommended for AGP by the vast majority of guidelines. For high‐risk/COVID positive patients, most countries recommended maximum protection and treatment in specialized dental clinics (22/30). Conclusion There was general agreement among recommendations for triage, mouth rinse, and PPE during AGP and treatment of potentially infectious patients. In contrast, recommendations on PPE for non‐AGP treatment varied considerably among the European countries possibly due to limited scientific evidence regarding transmission risk during non‐AGP treatments.

Abstract
This article highlights the results of a study of blood parameters in animals with simulated necrotizing ulcerative gingivitis and compares them, under the same conditions, with animals that received local treatment with a developed complex of antioxidant drugs. Following the work tasks, the nature of changes in the state of the antioxidant - prooxidant system and their influence on quantitative and functional indicators of markers of inflammatory intensity was analyzed and investigated during the pathological process in the background and without treatment with a developed complex. This work shows the changes of malonic dialdehyde concentration as an indicator of lipid peroxidation intensity in experimental animals, the level of catalase activity in the blood of animals, and antioxidant-prooxidant balance in the dynamics of necrotizing ulcerative gingivitis.

Abstract
Bacterial reinfection and root fracture are the main culprits related to root canal treatment failure. This study aimed to assess the utility of quercetin solution as an adjunctive endodontic irrigant that does not weaken root canal dentin with commitment anti-biofilm activity and bio-safety. Based on a noninvasive dentin infection model, dentin tubules infected with Enterococcus faecalis (E. faecalis) were irrigated with sterile water (control group), and 0, 1, 2, 4 wt% quercetin-containing ethanol solutions. Live and dead bacteria percentages in E. faecalis biofilms were analyzed by confocal laser scanning microscopy (CLSM). Elastic modulus, hydroxyproline release and X-ray photoelectron spectroscopy (XPS) characterization were tested to evaluate the irrigants’ collagen-stabilizing effect. The cytotoxicity was tested by CCK-8 assay. Quercetin increased the proportion of dead bacteria volumes within E. faecalis and improved the flexural strength of dentin compared to control group (p < 0.05). Quercetin-treated dentin matrix had less elasticity loss and hydroxyproline release after collagenase degradation (p < 0.05). Moreover, quercetin solutions revealed an increase in the C-O peak area under both C1s and O1s narrow-scan spectra of XPS characterization, and no cytotoxicity (p > 0.05). Quercetin exhibited anti-biofilm activity, a collagen-stabilizing effect with cytocompatibility, supporting quercetin as a potential candidate for endodontic irrigant.

Abstract
BACKGROUND Ventilator-associated pneumonia (VAP) is defined as pneumonia developing in people who have received mechanical ventilation for at least 48 hours. VAP is a potentially serious complication in these patients who are already critically ill. Oral hygiene care (OHC), using either a mouthrinse, gel, swab, toothbrush, or combination, together with suction of secretions, may reduce the risk of VAP in these patients. OBJECTIVES To assess the effects of oral hygiene care (OHC) on incidence of ventilator-associated pneumonia in critically ill patients receiving mechanical ventilation in hospital intensive care units (ICUs). SEARCH METHODS Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 25 February 2020), the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, 2020, Issue 1), MEDLINE Ovid (1946 to 25 February 2020), Embase Ovid (1980 to 25 February 2020), LILACS BIREME Virtual Health Library (1982 to 25 February 2020) and CINAHL EBSCO (1937 to 25 February 2020). We also searched the VIP Database (January 2012 to 8 March 2020). The US National Institutes of Health Trials Registry (ClinicalTrials.gov) and the World Health Organization International Clinical Trials Registry Platform were searched for ongoing trials. No restrictions were placed on the language or date of publication when searching the electronic databases. SELECTION CRITERIA We included randomised controlled trials (RCTs) evaluating the effects of OHC (mouthrinse, gel, swab, toothbrush or combination) in critically ill patients receiving mechanical ventilation for at least 48 hours. DATA COLLECTION AND ANALYSIS At least two review authors independently assessed search results, extracted data and assessed risk of bias in included studies. We contacted study authors for additional information. We reported risk ratio (RR) for dichotomous outcomes and mean difference (MD) for continuous outcomes, using the random-effects model of meta-analysis when data from four or more trials were combined. MAIN RESULTS We included 40 RCTs (5675 participants), which were conducted in various countries including China, USA, Brazil and Iran. We categorised these RCTs into five main comparisons: chlorhexidine (CHX) mouthrinse or gel versus placebo/usual care; CHX mouthrinse versus other oral care agents; toothbrushing (± antiseptics) versus no toothbrushing (± antiseptics); powered versus manual toothbrushing; and comparisons of other oral care agents used in OHC (other oral care agents versus placebo/usual care, or head-to-head comparisons between other oral care agents). We assessed the overall risk of bias as high in 31 trials and low in two, with the rest being unclear. Moderate-certainty evidence from 13 RCTs (1206 participants, 92% adults) shows that CHX mouthrinse or gel, as part of OHC, probably reduces the incidence of VAP compared to placebo or usual care from 26% to about 18% (RR 0.67, 95% confidence intervals (CI) 0.47 to 0.97; P = 0.03; I2 = 66%). This is equivalent to a number needed to treat for an additional beneficial outcome (NNTB) of 12 (95% CI 7 to 128), i.e. providing OHC including CHX for 12 ventilated patients in intensive care would prevent one patient developing VAP. There was no evidence of a difference between interventions for the outcomes of mortality (RR 1.03, 95% CI 0.80 to 1.33; P = 0.86, I2 = 0%; 9 RCTs, 944 participants; moderate-certainty evidence), duration of mechanical ventilation (MD -1.10 days, 95% CI -3.20 to 1.00 days; P = 0.30, I2 = 74%; 4 RCTs, 594 participants; very low-certainty evidence) or duration of intensive care unit (ICU) stay (MD -0.89 days, 95% CI -3.59 to 1.82 days; P = 0.52, I2 = 69%; 5 RCTs, 627 participants; low-certainty evidence). Most studies did not mention adverse effects. One study reported adverse effects, which were mild, with similar frequency in CHX and control groups and one study reported there were no adverse effects. Toothbrushing (± antiseptics) may reduce the incidence of VAP (RR 0.61, 95% CI 0.41 to 0.91; P = 0.01, I2 = 40%; 5 RCTs, 910 participants; low-certainty evidence) compared to OHC without toothbrushing (± antiseptics). There is also some evidence that toothbrushing may reduce the duration of ICU stay (MD -1.89 days, 95% CI -3.52 to -0.27 days; P = 0.02, I2 = 0%; 3 RCTs, 749 participants), but this is very low certainty. Low-certainty evidence did not show a reduction in mortality (RR 0.84, 95% CI 0.67 to 1.05; P = 0.12, I2 = 0%; 5 RCTs, 910 participants) or duration of mechanical ventilation (MD -0.43, 95% CI -1.17 to 0.30; P = 0.25, I2 = 46%; 4 RCTs, 810 participants). AUTHORS' CONCLUSIONS Chlorhexidine mouthwash or gel, as part of OHC, probably reduces the incidence of developing ventilator-associated pneumonia (VAP) in critically ill patients from 26% to about 18%, when compared to placebo or usual care. We did not find a difference in mortality, duration of mechanical ventilation or duration of stay in the intensive care unit, although the evidence was low certainty. OHC including both antiseptics and toothbrushing may be more effective than OHC with antiseptics alone to reduce the incidence of VAP and the length of ICU stay, but, again, the evidence is low certainty. There is insufficient evidence to determine whether any of the interventions evaluated in the studies are associated with adverse effects.

Abstract
Objectives Chlorhexidine (CHX) is a commonly used antiseptic mouthwash, used by dental practitioners and the public, due to its antimicrobial effects. The aim of this article was to provide a narrative review of current antimicrobial uses of CHX relevant to dentistry in the context of oral diseases, highlighting need for further studies to support its safe and appropriate use. Study selection, data and sources Randomised controlled trials, systematic reviews and national (UK and US) guidelines were consulted where available, with search terms for each subject category entered into MEDLINE, PubMed, Google Scholar and the Cochrane database. Results Some evidence existed to support adjunctive short-term use of CHX to manage dental plaque, and reduce clinical symptoms of gingivitis, dry socket, as well as reduce aerosolisation of bacteria. However, use must be weighed alongside the less desirable effects of CHX, including extrinsic staining of teeth, antimicrobial resistance to antiseptic agents and the rare, but fatal, allergic reactions to CHX. Conversely, evidence for the effectiveness of chlorhexidine to manage or prevent periodontitis, dental caries, necrotising periodontal diseases, peri-implantitis, and infections associated with extraction and aerosolised viruses remains less certain. Conclusions The use of CHX in dentistry and oral healthcare continues to be widespread and thus it is important that dental practitioners understand that, based on its differential mechanisms of action on different microbes, appropriate clinical and dental use of CHX should be oral disease specific. However, further scientific and clinical research is required before full recommendations can be made.

Abstract
BACKGROUND Alveolar osteitis (AO) may occur after molar extraction. Chlorhexidine (CHX) rinse and CHX gel are widely used to prevent AO. Although previous meta-analyses support the effectiveness of both CHX rinse and CHX gel in preventing AO, important issues regarding these two formulations have not been addressed adequately in the literature. PURPOSE A systematic review and meta-analysis of randomized controlled trials was conducted to determine the effectiveness of CHX rinse and CHX gel in preventing AO. METHODS PubMed, EMBASE, SCOPUS, and Cochrane databases were searched for randomized controlled trials published before June 2018. The risk ratio (RR) was used to estimate the pooled effect of AO incidence using a random-effect model. RESULTS The RRs of AO in patients treated with 0.12% CHX rinse (RR = 0.54, 95% CI [0.41, 0.72]) and 0.2% CHX rinse (RR = 0.84, 95% CI [0.52, 1.35]) were significantly lower than in those treated with the control. Moreover, a significantly lower RR was identified in patients treated with 0.2% CHX gel (RR = 0.47, 95% CI [0.34, 0.64]) than in those treated with the control. When CHX products of different concentrations were grouped together, patients treated with CHX rinse showed an RR of AO of 0.61 (95% CI [0.48, 0.78]) and those treated with CHX gel showed an RR of AO of 0.44 (95% CI [0.43, 0.65]). On the other hand, a meta-analysis of three trials that compared CHX rinse and CHX gel directly showed a significantly lower RR of AO in patients treated with CHX rinse than in those treated with CHX gel (RR = 0.56, 95% CI [0.34, 0.96]). CONCLUSIONS/IMPLICATIONS FOR PRACTICE The results support the effectiveness of both CHX rinse and gel in reducing the risk of AO after molar extraction. Each formulation provides unique benefits in terms of ease of application and cost. On the basis of the results of this study, the authors recommend that CHX gel be used immediately after molar extraction because of the convenience and cost-effectiveness of this treatment and that CHX rinse be used by the patient after discharge at home in combination with appropriate health education and case management.

Abstract
Cohort selection The aim was to evaluate interventions to minimise microbial contamination from aerosol generating procedures in the dental office. Seven electronic databases were searched using key words such as 'aerosols', 'droplets', 'spatter', 'microbial loads' etc to identify relevant randomised controlled trials and prospective non-randomised clinical trials until 6 April 2020.Data sources PubMed; Scopus; Cochrane Central Register of Controlled Trials; Cochrane Database of Systematic Reviews; Open Grey; ClinicalTrials.gov; National Research Register; and hand searches.Data analysis Eligible studies were analysed for effectiveness of various interventions on the microbial counts in the aerosols generated in the dental office using predefined criteria. Data were analysed for assessment of quality of evidence and confidence in the estimated effect, risk of bias and other analyses using Stata 15.1 software. PRISMA guidelines extension for network meta-analysis were followed for reporting.Results Initial search identified 266 studies, of which 35 were evaluated for full text. Finally, 29 studies fulfilled the eligibility criteria for qualitative synthesis. The majority of the included studies were published in the last decade, and 21 out of the 29 studies were randomised controlled trials. However, based on comparable procedural settings (study design, study populations, interventions and outcome measures), only 11 were eligible for contribution to the network meta-analysis. The setting of all interventions was ultrasonic scaling of adult patients in a clinical dental practice environment, and involved 16 direct and 29 indirect comparisons. A multivariate meta-analysis showed pre-procedural mouth rinse with tempered chlorhexidine 0.2% at 47°C was most effective in reducing post-procedural bacterial load compared to the control. A mean difference of -0.92 (95% CI -15.4 to -0.29) in log10 colony-forming units was observed in air samples within 90 cm of the dental unit.Conclusions Notwithstanding the limitations of this network meta-analysis, pre-procedural mouth rinse with tempered chlorhexidine appears to be most effective in reducing bacterial counts in aerosols generated during dental operative procedures. Further randomised controlled clinical trials based on robust designs are required to establish the effectiveness of antimicrobial agents in reducing aerosol-related microbial loads (bacteria and viruses) in clinical environments.

Abstract
AIMS The aim of this study was to investigate the effects of trans-cinnamaldehyde (TC) and its synergistic activity with chlorhexidine (CHX) and fluoride against Streptococcus mutans. METHODS AND RESULTS Streptococcus mutans UA159 was treated with TC alone and in combination with CHX or sodium fluoride. The synergy profile was analysed using the Zero Interaction Potency model. TC showed strong synergism (synergy score of 21·697) with CHX, but additive effect (synergy score of 5·298) with fluoride. TC and the combinations were tested for acid production (glycolytic pH drop) and biofilm formation by S. mutans, and nitric oxide production in macrophages. TC significantly inhibited sucrose-dependent biofilm formation and acid production by S. mutans. Mechanistic studies were carried out by qRT-PCR-based transcriptomic studies which showed that TC acts by impairing genes related to metabolism, quorum sensing, bacteriocin expression, stress tolerance and biofilm formation. CONCLUSIONS trans-Cinnamaldehyde potentiates CHX and sodium fluoride in inhibiting S. mutans biofilms and virulence through multiple mechanisms. This study sheds significant new light on the potential to develop TC as an anti-caries treatment. SIGNIFICANCE AND IMPACT OF THE STUDY Oral diseases were classified as a 'silent epidemic' in the US Surgeon General's Report on Oral Health. Two decades later, >4 billion people are still affected worldwide by caries, having significant effects on the quality of life. There is an urgent need to develop novel compounds and strategies to combat dental caries. Here, we prove that TC downregulates multiple pathways and potentiates the CHX and fluoride to prevent S. mutans biofilms and virulence. This study sheds significant new light on the potential to develop TC in combination with CHX or fluoride as novel treatments to arrest dental caries.

Abstract
Continuing cariogenic bacterial growth demineralizing dentine beneath a composite filling is the most common cause of tooth restoration failure. Novel composites with antibacterial polylysine (PLS) (0, 4, 6, or 8 wt%) in its filler phase were therefore produced. Remineralising monocalcium phosphate was also included at double the PLS weight. Antibacterial studies involved set composite disc placement in 1% sucrose-supplemented broth containing Streptococcus mutans (UA159). Relative surface bacterial biofilm mass (n = 4) after 24 h was determined by crystal violet-binding. Live/dead bacteria and biofilm thickness (n = 3) were assessed using confocal laser scanning microscopy (CLSM). To understand results and model possible in vivo benefits, cumulative PLS release from discs into water (n = 3) was determined by a ninhydrin assay. Results showed biofilm mass and thickness decreased linearly by 28% and 33%, respectively, upon increasing PLS from 0% to 8%. With 4, 6, and 8 wt% PLS, respectively, biofilm dead bacterial percentages and PLS release at 24 h were 20%, 60%, and 80% and 85, 163, and 241 μg/disc. Furthermore, initial PLS release was proportional to the square root of time and levelled after 1, 2, and 3 months at 13%, 28%, and 42%. This suggested diffusion controlled release from water-exposed composite surface layers of 65, 140, and 210 μm thickness, respectively. In conclusion, increasing PLS release initially in any gaps under the restoration to kill residual bacteria or longer-term following composite/tooth interface damage might help prevent recurrent caries.

Abstract
OBJECTIVE The aim of this case report was to document a case of delayed-type hypersensitivity reaction of the gingiva to chlorhexidine and review the literature on oral mucosal hypersensitivity reactions associated to chlorhexidine-containing oral hygiene products. STUDY DESIGN A 58-year-old man presented with a well-demarcated erythematous area on the right upper anterior gingiva. Incisional biopsy was performed. Postoperatively, chlorhexidine digluconate gel was prescribed twice a day, but the patient did not use it because he experienced intense burning immediately after the first application. The microscopic diagnosis was nonspecific mucositis. Hypersensitivity reaction was suspected. The patient reported use of 0.004% chlorhexidine digluconate-based toothpaste twice a day in the past few years. A delayed-type hypersensitivity reaction to the toothpaste was hypothesized, and its use was discontinued. Chlorhexidine, the common ingredient of both the toothpaste and the gel, was considered the allergen. The literature was reviewed on chlorhexidine-induced oral hypersensitivity reactions. RESULTS Two weeks after cessation of toothpaste use, complete remission of the lesion was observed without additional intervention. Four years later, no recurrence has been reported. The literature review yielded 7 studies reporting 20 patients with intraoral manifestations of hypersensitivity reactions associated with chlorhexidine-containing oral hygiene products. CONCLUSIONS Clinicians should be aware that oral hygiene products containing even low concentrations of chlorhexidine might induce hypersensitivity reactions.

Abstract
INTRODUCTION Literature shows upcoming allergy to chlorhexidine due to the widespread use of the disinfectant within and outside surgical settings. Only a few case reports have been published regarding the use of topical chlorhexidine disinfectant outside surgery and only a minority of these within the pediatric population. CASE REPORT We present a case-report of a teenager, treated for acute lymphoblastic leukemia who developed an anaphylactic shock after repeated chlorhexidine use for skin disinfection at the insertion of a central venous catheter during his chemotherapy treatment. Preceding minor symptoms such as local swelling and pruritus were not recognized as possible allergy to chlorhexidine.Management and outcome: He was treated with two doses of intramuscular adrenaline and transferred to the pediatric intensive care unit where he fully recovered. Specific IgE testing was positive for chlorhexidine. A total avoidance of chlorhexidine was instructed. DISCUSSION A similar case was published regarding an anaphylaxis after use of chlorhexidine disinfectant for a dialysis catheter. Almost all other case reports of anaphylactic shock were found within surgical settings or after insertion of an impregnated central venous catheter/urine catheter. We suggest that some of the disinfectant might have been flushed in the catheter and then caused an anaphylactic reaction. The link between symptoms and chlorhexidine was not made until an anaphylactic reaction occurred. Literature data show that chlorhexidine often causes mild preceding symptoms before an anaphylaxis occurs. So let awareness arise around this 'hidden allergen' of which warning reactions often are being missed.

Abstract
Antimicrobials are important adjuncts in the treatment of caries and periodontitis. However, increased bacterial resistance and hypersensitivity reactions to commonly used antimicrobials have led to an increasing demand for safe and natural substances. The objective of this study was to investigate the antibacterial effects of ε-polylysine against oral pathogens Streptococcus mutans and Porphyromonas gingivalis. Broth dilution assay, scanning electron microscopy (SEM) and confocal laser scanning microscopy (CLSM) analyses were performed to explore the antibacterial effect of ε-polylysine against S. mutans strain ATCC25175 and P. gingivalis strain ATCC332277. For the test solution, ε-polylysine was added to the bacterial suspension to prepare 0.125%, 0.25%, 0.5% and 1% ε-polylysine solutions diluted in broth medium. All four concentrations demonstrated complete inhibition of S. mutans and significantly reduced viable cell counts of P. gingivalis after 24 h. From starting inoculum of 9.15 log CFU/mL, P. gingivalis cell counts reduced to 4.01 log CFU/mL in the 0.125% ε-polylysine treatment group. SEM, CLSM, and the LIVE/DEAD bacterial assay of ε-polylysine application on P. gingivalis biofilm-dentin specimens revealed bacterial cell membrane disruption and irregular cell morphologies. The results indicated satisfactory antibacterial efficacy of ε-polylysine against P. gingivalis and S. mutans in liquid medium and as an application on biofilm-dentin specimens.

Abstract
Chlorhexidine is a synthetic bisbiguanide antiseptic and was introduced in healthcare use in 1954. Allergy to chlorhexidine has been increasingly reported particularly in the perioperative and medical procedural settings. The hypersensitivity reactions range from mild cutaneous reactions to anaphylaxis or death. There are many products and medical devices containing chlorhexidine that sometimes lack standardized labeling. With the various routes of chlorhexidine exposure, accidental or recurrent reactions in chlorhexidine-allergic patients have been reported. Therefore, we aim to review the most recent evidence in clinical manifestations, diagnostic methods, management, and preventive measures with a focus on the unique features of chlorhexidine allergy.

Abstract
Complex oral surgery procedures are occurring more commonly in primary care, performed by both specialist oral surgeons and non-specialists/tier 2 providers. Practitioners in the UK are working in an increasingly litigious environment which is often at the forefront of a practitioner's mind and prevention of complaints and claims of negligence is vital in maintaining confidence in our practise. In this ever-increasing litigious environment practitioners need to be aware of the risks associated with oral surgery procedures and have to be able to assess and treatment plan patients effectively and safely. Consent is critical to all procedures, and the recent Montgomery case reinforces the importance of this process which must be individual to each patient. It is vital that as practitioners we are aware of our scope of practice and are able to fully inform patients of the risks and benefits of treatment. Practitioners must know their limits and when to refer on to secondary care. This paper discusses the essentials of risk management in oral surgery and describes key stages in the management of patients undergoing an oral surgery procedure. Initial assessment of the patient, which includes medical and dental history will be discussed followed by investigations to support the clinical diagnosis. Once diagnosis has been confirmed, the process of obtaining consent and the legal implications of this are discussed. Finally, a discussion on the appropriate evidence-based management of common complications which may arise when performing oral surgery will complete the paper.

Abstract
Oral colonisation by pathogens contributes to contracting ventilator-associated pneumonia (VAP). The aim of this review was to determine whether the use of the antiseptic chlorhexidine in the intra-oral cavity reduced its incidence in the critically ill, mechanically ventilated adult. The findings from this review led to the conclusion that chlorhexidine reduced the occurrence of VAP. Although a recommendation to implement the use of intra-oral chlorhexidine for mechanically-ventilated patients within critical care can be made, further exploration into required frequency and method of administration would be beneficial to reduce unnecessary exposure and hinder pathogenic resistance.

Abstract
CONTEXT Oil pulling procedure involves swishing of oil in the mouth for various oral health benefits. AIM The aim of the study was to evaluate the effectiveness of sesame oil (SO), ozonated SO (OSO), and chlorhexidine (CHX) mouthwash on the oral health status of adolescents. STUDY SETTINGS AND DESIGN Parallel multi-arm double-blinded randomized trial was done in a Government higher secondary school. MATERIALS AND METHODS A total of 75 adolescents aged 12-14 years with decay-missing-filled index ≤3 were randomly assigned to three groups (n = 25): Group I (SO), Group II (OSO), and Group III (CHX mouthwash). Baseline (T1) Debris Index (DI-S), Calculus Index (CI-S), Oral Hygiene Index-Simplified (OHI-S), Plaque Index (PI), and salivary Streptococcus mutans count were recorded. All the groups were subjected to intervention with the respective mouth rinses for 15 days. The index scores and the salivary S. mutans count were reassessed after 15 days (T2) and 1 month (T3), and the results were statistically analyzed. STATISTICAL ANALYSIS The statistical analysis was done using IBM SPSS Statistics for Windows. The statistical significance was set at P ≤ 0.05. Kolmogorov-Smirnov and Shapiro-Wilk test were used to test the normality of the data. The Friedman test and Wilcoxon-signed rank test were carried out for intragroup comparison. Kruskal-Wallis and Mann-Whitney U-test were employed to analyze inter-group comparison. RESULTS All the groups showed statistically significant reduction in DI-S, CI-S, OHI-S, PI, and S. mutans count after 15 days. CONCLUSION Oil pulling therapy using SO and OSO showed a significant improvement in oral hygiene.

Abstract
This study aims to evaluate the in vitro antimicrobial and immunomodulatory activities and cytotoxicity of chlorhexidine (CHX) and synoeca-MP peptide alone or in combination against Pseudomonas aeruginosa. The antimicrobial property was evaluated by the determination of minimal inhibitory concentration, minimum bactericidal concentration, and planktonic bacteria and biofilm inhibition. Immunomodulatory activity was determined by enzyme-linked immunosorbent assay and nitric oxide production by the Griess reaction method. According to the results, synoeca-MP combined with CHX demonstrated antimicrobial effectiveness compared with its isolated use, in addition to immunomodulatory activity (upregulating MPC-1 and tumor necrosis factor-α and downregulating nitric oxide and interleukin-10). In this context, it is expected that the substances, together, could be capable of controlling bacterial infection and dissemination, besides potentiating macrophages' immune response against the studied microorganism. Moreover, reducing the CHX concentration by the addition of synoeca-MP peptide may, in a beneficial way, minimize the undesirable effects of both, CHX and synoeca-MP in a clinical setting.

Mohammed HA, Abdel-Aziz MM, Hegazy MM. Anti-Oral Pathogens of Tecoma stans (L.) and Cassia javanica (L.) Flower Volatile Oils in Comparison with Chlorhexidine in Accordance with Their Folk Medicinal Uses. ACTA ACUST UNITED AC 2019; 55:medicina55060301. [PMID: 31238555 PMCID: PMC6631167 DOI: 10.3390/medicina55060301] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2019] [Revised: 06/04/2019] [Accepted: 06/18/2019] [Indexed: 01/27/2023]
Abstract
Background and Objectives: Teeth decay and plaque are complicated problems created by oral pathogens. Tecoma stans (L.) and Cassia javanica (L.) are two ornamental evergreen plants widely distributed in Egypt. These plants are traditionally used for oral hygienic purposes. This study aims to elucidate the volatile oil constituents obtained from the flowers of these plants and evaluate the antimicrobial activity of these volatile oils against specific oral pathogens in comparison to chlorhexidine. Materials and Methods: The flowers obtained from both plants were extracted by n-hexane. GC-MS spectrometry was used to identify the constituents. Minimum inhibitory concentrations (MICs) were measured using tetrazolium salt (2,3-bis[2-methyloxy-4-nitro-5-sulfophenyl]-2H-tetrazolium-5-carboxanilide) (XTT). Results: GC-MS analysis revealed the presence of 32 and 29 compounds, representing 100% of the volatile constituents of Tecoma stans and Cassia javanica, respectively. The GC-MS analysis showed more than 60% of the volatile oil constituents are represented in both plants with different proportions. Chlorhexidine exerted stronger activity than tested plants against all microorganisms. Cassia javanica flower extract was more active against all tested microorganisms than Tecoma stans. Of note was the effect on Streptococcus mutans, which was inhibited by 100% at 12.5 and 25 µg/mL of Cassia javanica and Tecoma stans, respectively. The growth of Lactobacillus acidophilus was also completely inhibited by 25 µg/mL of the Cassia javanica extract. MIC90 and MIC were also calculated, which revealed the superiority of Cassia javanica over Tecoma stans against all tested oral pathogens. Conclusion: Cassia javanica flower volatile oils showed a potential anti-oral pathogen activity at relatively low concentrations. Also, Cassia javanica and Tecoma stans demonstrated a strong activity against tooth decay's notorious bacteria Streptococcus mutans. Both plants can be potential substituents to chlorhexidine. Formulating the constituents of these plants in toothpastes and mouthwashes as anti-oral pathogen preparations can be an interesting future plan.

Chlorhexidine allergy in the perioperative setting: a narrative review. Br J Anaesth 2019; 123:e95-e103. [PMID: 30955832 DOI: 10.1016/j.bja.2019.01.033] [Citation(s) in RCA: 54] [Impact Index Per Article: 10.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2018] [Revised: 01/04/2019] [Accepted: 01/26/2019] [Indexed: 02/03/2023] Open
Abstract
Chlorhexidine is an antiseptic with a broad spectrum of activity and a persistent effect on skin. Consequently, it has become an ubiquitous antiseptic in healthcare and the community. As use has become widespread, increasing numbers of cases of allergy have been reported in the literature, including cases of anaphylaxis to chlorhexidine gels used on mucous membranes, chlorhexidine-impregnated devices such as central venous catheters, chlorhexidine preparations used on wounds and broken skin, and cases after dental procedures. Numerous governmental warnings have been issued over recent decades to warn of the risk of allergy to chlorhexidine on mucosal surfaces or in medical devices. Whilst the number of published cases likely underestimates the true prevalence of reactions, we retrospectively surveyed clinics with experience in investigating perioperative chlorhexidine allergy. Despite differences in investigation practice before the survey took place, 13 clinics responded which together had diagnosed 252 cases of anaphylaxis to chlorhexidine, and cases of delayed allergy. In eight of 13 clinics, chlorhexidine was within the top four most commonly diagnosed causes of perioperative anaphylaxis. Despite this, the incidence of anaphylaxis to chlorhexidine is low given that patients are very commonly exposed. Sensitisation of healthcare workers can occur, but is uncommon. Before exposing patients to this antiseptic, consideration of the potential risk vs benefit should be undertaken, particularly for higher risk exposures, such as mucosal exposure or i.v. exposure via impregnated lines. Difficulties exist in protecting patients with known allergies from re-exposure to chlorhexidine, which would be improved with uniform labelling and chlorhexidine product registers.

Abstract
PURPOSE OF REVIEW In recent years, the risk of allergy to chlorhexidine is increasingly recognised. In this review, we discuss why the allergy is so easily overlooked and point out several preventative initiatives that can minimise the risk of both chlorhexidine sensitisation and allergy development and accidental re-exposure in patients with chlorhexidine allergy. Testing for chlorhexidine allergy is also discussed. RECENT FINDINGS Numerous reports have been published from many different specialties. Symptoms range from mild skin symptoms to life-threatening anaphylaxis. Testing for chlorhexidine allergy is based on skin testing and in vitro testing. Recently, it was found that both skin prick testing and specific IgE have high sensitivities and specificities. This review gives an overview of chlorhexidine allergy with a special focus on preventative initiatives and testing.

A multicentre, prospective, randomised controlled open trial. CRITICAL CARE : THE OFFICIAL JOURNAL OF THE CRITICAL CARE FORUM 2018; 22:272. [PMID: 30368249 PMCID: PMC6204275 DOI: 10.1186/s13054-018-2209-4] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/13/2018] [Accepted: 09/25/2018] [Indexed: 01/14/2023]
Abstract
Background Pathogenic enteric bacteria aspirated from the oropharynx are the main cause of ventilator-associated pneumonia (VAP). Using chlorhexidine (CHX) orally or selective decontamination has been shown to reduce VAP. In a pilot study we found that oral care with the probiotic bacterium Lactobacillus plantarum 299 (Lp299) was as effective as CHX in reducing enteric bacteria in the oropharynx. To confirm those results, in this expanded study with an identical protocol we increased the number of patients and participating centres. Methods One hundred and fifty critically ill patients on mechanical ventilation were randomised to oral care with either standard 0.1% CHX solution (control group) or a procedure comprising final application of an emulsion of Lp299. Samples for microbiological analyses were taken from the oropharynx and trachea at inclusion and subsequently at defined intervals. Student’s t test was used for comparisons of parameters recorded daily and Fisher’s exact test was used to compare the results of microbiological cultures. Results Potentially pathogenic enteric bacteria not present at inclusion were identified in oropharyngeal samples from 29 patients in the CHX group and in 31 samples in the probiotic group. Considering cultures of tracheal secretions, enteric bacteria were found in 17 and 19 samples, respectively. Risk ratios show a difference in favour of the Lp group for fungi in oropharyngeal cultures. VAP was diagnosed in seven patients in the Lp group and in 10 patients among the controls. Conclusions In this multicentre study, we could not demonstrate any difference between Lp299 and CHX used in oral care procedures regarding their impact on colonisation with emerging potentially pathogenic enteric bacteria in the oropharynx and trachea.
