Oral Health Literacy and Patient Education Practices Among Non-Dental Professionals in Chongqing, China: A Cross-Sectional Study.

BACKGROUND Preventing oral diseases is a critical aim in maintaining general health. Non-dental professionals (NDPs) should understand oral health-related knowledge to help patients maintain oral and general health. We investigated the oral health knowledge, behaviors, and attitudes of NDPs regarding patient education and intersectoral collaborations for oral health. MATERIAL AND METHODS For this cross-sectional study, a web-based questionnaire of 36 questions was designed to collect characteristics, oral health knowledge, behaviors, and attitudes of spreading oral health knowledge. A total of 406 NDPs, including 166 doctors and 240 nurses, at 3 randomly selected hospitals in Chongqing, China, were included. Data were collected electronically and statistically analyzed using the chi-square test. RESULTS Only 35.96% and 39.41% of respondents disagreed with "extraction can cause loosening of adjacent tooth" and "tooth loss is a natural part of aging", respectively. Of the respondents, 92.12% were aware of oral healthcare needs before pregnancy; 67.48% agreed with cleaning the gums before the eruption of children's teeth; only 57.14% and 56.16% knew the start time of dental cleaning for children and the relatively safe period of dental treatment for pregnant women, respectively; 73.40% of respondents were interested in oral health knowledge, and they mainly consulted dental professionals; 95.56% agreed with intersectoral collaborations for oral health; and 68.47% thought to conduct oral health education in the future. CONCLUSIONS NDPs knew about common oral health knowledge; however, the oral healthcare knowledge for special groups was insufficient. NDPs should improve their ability to educate the public on oral health and establish intersectoral collaborations.

Impact of oral health literacy on oral health behaviors and outcomes among the older adults: a scoping review.

BACKGROUND: Oral Health Literacy (OHL), defined as an ability to obtain, understand, and apply information related to oral health, plays a crucial role in promoting effective oral health outcomes and behaviors. Given the pressing need to enhance oral health among older adults, this scoping review aims to summarize the impact of OHL on oral health behaviors and outcomes in this population. METHODS: The authors performed an electronic search up through July 22, 2024. Among the 2,226 articles identified, the authors included studies in which the investigators evaluated the association between OHL and oral health behaviors or outcomes restricted to individuals aged 60 years and older. Thematic analysis was used to develop the domain for oral health behaviors or outcomes. RESULTS: Among the 10 studies analyzed, significant correlations were identified between OHL and various oral health indicators, including periodontitis, the number of remaining teeth, dental prosthesis use, oral hygiene, oral health-related quality of life among men, as well as dissatisfaction with oral health (p < 0.05). However, the results were conflicting across the studies, indicating variability in the strength and nature of these associations. Additionally, OHL was shown to significantly influence oral health-related behaviors, especially the tooth brushing frequency (p < 0.05). CONCLUSIONS: This review highlights a scarcity of studies addressing OHL in older populations, suggesting that OHL has been deprioritized in efforts to improve oral health for this vulnerable group. Key gaps include the need for age-appropriate OHL assessment tools, stronger evidence linking OHL to specific oral health behaviors and outcomes, and the integration of OHL into broader health initiatives and research in older group. These areas are critical to advancing our understanding and improving oral health outcomes among older adults.

Effectiveness of Motivational Interviewing and cross platform messaging application in improving oral health knowledge, attitude and behaviours among pregnant women- A Randomized Controlled Trial.

Background: Body goes through significant hormonal and physiological changes during pregnancy, which could be linked to changes in oral health. Many women are unaware of the negative consequences of poor dental health during and after pregnancy, both for themselves and their children. Therefore, this study aimed to assess the effectiveness of Motivational Interviewing (MI) and cross platform messaging application (WhatsApp messenger) for oral health education on the oral health knowledge, attitude and behaviours among pregnant women attending ante natal care. Methods: A randomized controlled trial was conducted among 84 pregnant women. Simple random sampling was employed to select participants after oral examination. Participants were randomly allocated to two groups (Group 1: Cross-platform messaging application [WhatsApp]; Group 2: MI) using a lottery method. Pregnant women aged 18 years and older, gestational age between 8 and 30 weeks were included. A face-to-face interview and oral examination were conducted to assess baseline knowledge and oral hygiene status. A follow-up examination was conducted after one month of intervention. Inferential statistics, including the chi-square test and independent t-test, were used to compare variables between the two groups. Results: The mean knowledge score at baseline was comparable between Group 1 (WhatsApp) and Group 2 (MI). However, post-intervention, Group 2 showed a significantly higher mean knowledge score compared to Group 1. Post-intervention, Group 2 exhibited a significantly better oral hygiene status compared to Group 1. Significant improvements in oral health behaviours were observed in Group 2 compared to Group 1 (p < 0.001). Conclusions: The findings suggested that while both interventions were effective, MI showed superior results in improving knowledge, oral hygiene status, and oral health behaviours. The personalized and client-centred approach of MI enables participants to explore and resolve ambivalence, promoting a deeper understanding of the importance of oral health during pregnancy.

Influence of different cleaning methods on the concentration of airborne endotoxins and microbial aerosols in the oral clinical environment.

AIM: This study aims to evaluate the effectiveness of various cleaning methods in reducing airborne endotoxin and microbial aerosols during oral cleaning procedures. METHOD: Forty patients undergoing oral cleaning procedures were randomly assigned to one of four groups (n = 10 per group). Group A received strong suction alone; Group B received strong suction combined with an air disinfection machine; Group C received strong suction combined with a dental electric suction machine; Group D received strong suction in conjunction with both an air disinfection machine and a dental electric suction machine. Airborne aerosol concentrations were assessed at four-time points: before treatment, 30 min into treatment, immediately after treatment, and 60 min after treatment ended. Samples were collected at distances of 20 cm, 60 cm, and 1 m from the patient's oral cavity using the natural sedimentation method. T-test was used to evaluate the difference among tested groups. RESULTS: Airborne endotoxins and microbial aerosols levels increased significantly during treatment, with the highest levels observed at 20 cm from the patient's mouth. During treatment, groups with additional cleaning methods (Groups B, C, and D) exhibited higher levels of airborne endotoxins and microbial aerosols compared to Group A (strong suction alone). However, post-treatment analysis revealed that Group D demonstrated the lowest level of airborne endotoxins and microbial aerosols, while Group A exhibited the highest. CONCLUSIONS: Implementing effective aerosol management strategies can significantly reduce aerosol dispersion in the oral clinical environment. Continuous monitoring aerosol concentrations and the application of appropriate control measures are essential for minimizing infection risks for both patients and healthcare providers during oral cleaning procedures.

Content quality and reliablity of YouTube™ videos as a source of information about good oral hygiene practices in adults.

Background: Good oral hygiene is crucial for preventing dental caries and periodontal diseases. However, proper and regular application of oral hygiene practices requires adequate knowledge. In recent years, the internet has become one of the most popular places to find health-related information, necessitating studies that analyze the quality of the content available online. The purpose of the present study was to analyze the content quality and reliability of YouTube™ videos on the topic of adult oral hygiene practices and to guide oral health care professionals who use this platform for patient education. Methods: A YouTube™ search was performed of the most frequent search term, 'dental hygiene'. A total of 150 videos were screened, and 51 were included in the final study. The characteristics, sources, and content of the videos were analyzed using the Global Quality Score (GQS) and DISCERN reliability indices. The IBM SPSS 25 program was used for statistical analyses. Results: Most of the included videos were uploaded by oral health care professionals (63%). GQS revealed only 17.6% of the videos were excellent quality whereas 23.5% of them were poor quality. In the content analysis, 62.7% of the videos were deemed moderately useful. Video duration, total content score, and interaction indices were all significantly higher in the useful and very useful groups compared to the slightly useful group (p = 0.020, p < 0.001, p = 0.040). GQS had a positive, low-medium statistically significant correlation with both video duration and total content scores (r = 0.235, r = 0.517; p < 0.05). DISCERN score also had a positive, low-medium statistically significant correlation with total content score (r = 0.500; p < 0.05). Conclusion: The study concluded that most YouTube™ videos on oral hygiene practices for adults are moderately useful. When using YouTube™ for patient education, oral health care professionals and organizations should be aware of low-quality videos and seek out accurate, useful videos. There is also a need for quality videos with expanded oral health content.

Tongue brushing enhances the myoelectric activity of the suprahyoid muscles in older adults: a six-week randomized controlled trial.

Tongue brushing improves respiratory function in older adults. Considering connection between the respiratory-related and suprahyoid muscles, this study aimed to investigate whether tongue-brushing interventions can improve myoelectric activity during respiration. A six-week randomized controlled trial was conducted in Kitakyushu, Japan, with 50 participants aged ≥ 65 years. The participants were allocated to the intervention (tongue brushing with routine oral hygiene) or control (routine oral hygiene alone) groups. Surface electromyography (sEMG) was used to assess the myoelectric activity of the suprahyoid muscles during inhalation, exhalation, and forced vital capacity (FVC). A survey was conducted at baseline and the end of the follow-up period. Thirty-six participants were recruited for the analysis. The root mean squares (RMS) of sEMG during exhalation increased significantly at the end of the follow-up period compared with that at baseline in the intervention group [48.7 (18.0-177.5) vs. 64.9 (21.6-163.0), p = 0.001], but not in the control group. The generalized linear model revealed that the ratio of change in FVC was correlated with the change in the RMS of sEMG of the suprahyoid muscles during exhalation after adjusting for potential confounders. Tongue brushing enhances the myoelectric activity of the suprahyoid muscle.

Comparative Efficacy of Medium and Soft Toothbrushes in Plaque Removal and Gingivitis Control.

BACKGROUND Regularly removing dental plaque is key to good oral hygiene and gingival health promotion. This study aimed to compare the effects of using soft and medium toothbrushes using the plaque index (PI), gingival index (GI), and bleeding on probing (BOP) index. MATERIAL AND METHODS A randomized parallel-group study design was used. Sixty-four participants were randomly assigned to 2 similar intervention groups (medium and soft toothbrush groups). The PI, GI, and BOP indexes were used. The median and median difference of PI, GI, and BOP were calculated. SPSS was used for data entry and analysis. Wilcoxon and Mann-Whitney U tests were used for data analysis. RESULTS The median scores of GI, PI, and BOP significantly decreased from 1.8, 1.7, and 2.0, respectively, before using medium toothbrushes to 0.0, 0.1, and 0.0, respectively, after using medium toothbrushes (all P<0.0001). Similarly, the median scores of GI, PI, and BOP significantly decreased from 2.0, 1.7, and 2.0, respectively, before using soft toothbrushes to 1.1, 0.9, and 1.0, respectively, after using soft toothbrushes (P<0.0001). The median differences in GI, PI, and BOP scores among those using medium toothbrushes were higher than the median differences among those using soft toothbrushes [(1.8 vs 0.9), (1.6 vs 0.8), and (2.0 vs 1.0), respectively]. These differences were statistically significant (P<0.0001). CONCLUSIONS This study concludes that medium and soft toothbrushes were effective in removing plaque and controlling gingivitis. Medium toothbrushes were more effective than soft toothbrushes in achieving these outcomes.

A randomised controlled trial to evaluate the effectiveness of personalised oral hygiene advice delivered via video technology.

OBJECTIVES: To determine whether video-technology oral hygiene advice (OHA) improved clinical plaque and bleeding on probing (BOP) scores in individuals diagnosed with gingivitis, compared to conventional OHA after 3-months. METHODS: This parallel, randomised 2-arm treatment, single-centre study, assessed Turesky Plaque Index (TPI) and BOP at baseline and 3-months in adult participants with mild-moderate gingivitis. Eligible participants with smartphones were randomised at baseline to intervention (tailored video OHA), or control (conventional OHA). Oral hygiene (OH) habits/attitudes were recorded with a questionnaire. All participants used a manual toothbrush with anti-gingivitis toothpaste twice daily. RESULTS: 57 participants completed the study. Both groups had improved gingival health (BOP) after 3-months, change from baseline being significantly greater in the intervention group (12.21% vs 6.80 %, p < 0.05). TPI scores decreased more in the intervention than control group, but the difference did not reach significance (1.15 vs 0.92, p = 0.079). OH habits and attitudes were similar at baseline and few differences between the groups were observed after 3-months, however frequency of interdental brush use was significantly increased, while self-rated oral health was significantly decreased in the intervention as compared to control group at this timepoint (p < 0.05). CONCLUSIONS: The combination of an individually tailored instructional video with appropriate toothbrushing using anti-gingivitis toothpaste and interdental brush, significantly improved participants' gingival health over 3-months compared to brushing with an anti-gingivitis toothpaste with conventional OHA as delivered in the general dental services. This study demonstrates the benefit of changing OH behaviour and delivering OHA using an individually tailored approach with contemporary methodology. CLINICAL SIGNIFICANCE: OHA is usually verbally delivered over short time periods. This study demonstrates video technology with individualised OHA improves OH adherence and empowers individuals, the recipient receiving personal visual cues with ability to replay advice and technique reiteration. This real-world technology could be better utilised in general dental practice.

Assessment of Motivations, Treatment Risks, and Oral Health in Adults with Fixed Orthodontic Care: A Cross-Sectional Study.

Aim: This cross-sectional study aims to investigate the reasons why adults seek orthodontic treatment, their perceived treatment risks, oral hygiene habits, and awareness of oral health. Materials and Methods: This study, which involved 246 adults, used a self-report questionnaire to collect sociodemographic data and examine the participants' understanding of oral health, self-assessment of oral health status, adherence to oral hygiene routines, and use of oral hygiene products. In addition, the reasons for opting for orthodontic treatment, negative associations, and expected outcomes were examined. The collected data were subjected to statistical analysis, including descriptive and regression methods. Results: The results showed that factors such as previous oral health education and regular use of specialized toothbrushes, including rotary toothbrushes, were significantly associated with higher knowledge levels (p < 0.05). However, daily oral hygiene practices were suboptimal, with the low utilization of aids: only 58.9% reported using interdental brushes, and 36.6% used dental floss regularly. Commonly reported dental problems included food debris between teeth (46.3%), tartar (35.4%), and tooth sensitivity to cold (26.4%). The primary motivations for orthodontic treatment were aesthetic improvement (63.8%), enhancements in oral function (49.6%), and addressing psychosocial concerns (42.7%). In contrast, the most frequently mentioned negative aspects associated with fixed orthodontic treatment were aesthetic concerns (30.9%), treatment duration (27.6%), and mouth ulcers (24.0%). Conclusions: Based on the research findings, regular oral hygiene education is recommended for adult patients considering fixed orthodontic therapy, including the use of additional tools such as interdental brushes and floss to improve oral health and reduce the risk of complications during treatment. The importance of chemical compounds in dentifrices and mouthwashes cannot be overstated, as they play a crucial role in addressing various dental issues. In addition, it is crucial to carefully weigh the pros and cons of therapy and to visit a dentist regularly to maintain oral health and monitor progress during treatment.

Oral Hygiene With Neutral Electrolyzed Water and Systemic Therapy Increases Gastric Helicobacter pylori Eradication and Reduces Recurrence.

OBJECTIVES: Helicobacter pylori gastric infection strongly correlates with gastric diseases such as chronic gastritis, functional dyspepsia, and complications such as peptic ulcers and gastric cancer. In developing countries, systemic therapies are not usually successful due to elevated antibiotic resistance. Additionally, oral H. pylori infection and periodontal disease correlate with gastric treatment failures. This study aimed to explore the effect of an integral therapy, comprising oral hygiene and concomitant systemic treatment, to increase the eradication of gastric infection and recurrences. MATERIALS AND METHODS: A prospective, randomized, four-arm, parallel-group, open-label clinical trial was conducted to investigate the efficacy of integral therapy to eradicate gastric H. pylori infection and avoid recurrences in double-positive (real-time PCR oral and gastric infection) patients. Oral hygiene involved mouthwash with neutral electrolyzed water (NEW), with or without periodontal treatment. One hundred patients were equally distributed into four groups: NS, NS-PT, NEW, and NEW-PT. All patients had concomitant systemic therapy and additionally, the following oral treatments: mouthwash with normal saline (NS), periodontal treatment and mouthwash with normal saline (NS-PT), mouthwash with NEW (NEW), and periodontal treatment and mouthwash with NEW (NEW-PT). Gastric and oral infection and symptoms were evaluated one and four months after treatments. RESULTS: Integral therapy with NEW-PT increased gastric eradication rates compared with NS or NS-PT (84%-96% vs. 20%-56%; p < 0.001). Even more, a protective effect of 81.2% (RR = 0.1877; 95% CI: 0.0658-0.5355; p = 0.0018) against recurrences and 76.6% (RR = 0.2439; 95% CI: 0.1380-0.4310; p < 0.001) against treatment failure (eradication of infection and associated symptoms) was observed in patients from the NEW and NEW-PT groups. CONCLUSIONS: Implementation of oral hygiene and systemic treatment can increase the eradication of gastric infection, associated symptoms, and recurrences. NEW is recommended as an antiseptic mouthwash due to its efficacy and short- and long-term safety.

Evaluating the impact of oral hygiene instruction and digital oral health education within cardiac rehabilitation clinics: A protocol for a novel, dual centre, parallel randomised controlled trial.

INTRODUCTION: Diseases of the periodontal tissues including gingivitis and periodontitis can affect up to 90% and 50% of the population respectively. These conditions are multifactorial inflammatory conditions involving a dysbiotic biofilm that, if left untreated, can lead to the destruction of the supporting structures of the teeth and have significant systemic implications, specifically on cardiovascular health. The elevation of inflammatory markers, particularly high-sensitive C-reactive protein (hsCRP), are strongly associated with an increased risk of atherosclerosis, a key risk factor for cardiovascular disease (CVD). HsCRP as well as other inflammatory markers can be detected in blood samples as early as 21 days after ceasing toothbrushing, due to the immune response to stagnant oral biofilm. The most effective way to ensure oral biofilm cannot remain on oral tissues, thus preventing periodontitis and reducing inflammatory CVD risk, is with good oral hygiene. The primary aim of this study is to assess whether individualised oral hygiene instruction (OHI) partnered with a digital oral health education (DOHE) package can improve the oral health of patients living with CVD. METHODS AND ANALYSIS: A total of 165 participants will be recruited from the Westmead and Blacktown Mt Druitt cardiac rehabilitation out-patient clinics into this dual centre, single blind, parallel design, randomised controlled trial. A baseline oral health clinical examination will be completed, followed by a self-report questionnaire before they are randomised in a 1:1:1 ratio into one of 3 arms as follows: individualised OHI partnered with DOHE (Group A), (Group B) DOHE only (Group B), and control/usual care (no oral health education) (Group C). Groups will have their intervention repeated at the 6-week follow-up. After completing the 12-week follow-up, Group B and Group C will receive tailored OHI. Group C will also receive the DOHE package. The primary outcome is the change in approximal plaque index score between baseline and 6-week follow up. ETHICS AND DISSEMINATION: The study has been approved by the Western Sydney Local Health District Human Ethics Committee 2023/ETH00516. Results will be published in peer-reviewed journals and presented at conferences. TRIAL REGISTRATION NUMBER: ACTRN12623000449639p ANZCTR: https://www.anzctr.org.au/.

MASCC/ISOO clinical practice statement: Current understanding on controversies in basic oral care in hemato-oncology and hematopoietic cell transplantation.

PURPOSE: A MASCC/ISOO Clinical Practice Statement (CPS) is aimed at generating a concise tool for clinicians, which concentrates on practical information needed for the management of oral complications of cancer patients. This CPS is focused on the current understanding of controversies that may arise while providing basic oral care in hemato-oncology patients and hematopoietic cell transplantation recipients (HCT). The CPS will summarize and elucidate controversies that have appeared in the literature and professional discussions. METHODS: This CPS was developed based on a critical evaluation of the literature followed by a structured discussion of a group of leading experts, members of the Oral Care Study Group of MASCC/ISOO. The information is presented in the form of succinct bullets to generate a short manual about the best standard of care. RESULTS: Controversies about the use of chlorhexidine (CHX) oral rinse, mechanical dental plaque removal procedures, the need for toothbrush replacement during phases of low blood cell counts, and the use of lidocaine mouthwash for oral pain were identified and discussed. Consensus about the best standard of care was outlined. CONCLUSION: The following ratifications are applicable for oral care in hemato-oncology patients and patients undergoing HCT: (1) CHX may reduce the risk of oral infections, although it was not found to reduce the risk of oral mucositis. (2) Toothbrushing and proficient interproximal cleaning should not be discouraged during HCT. (3) Toothbrushes do not need to be replaced daily and are preferred over cleansing swabs. (4) Lidocaine rinse, swish and spit, may be considered to palliate oral mucosal pain if applied in a certain manner.

Experiences of Individual Care Workers in Oral Care of Dementia Patients.

Objective: Dementia is one of the most common diseases in the elderly population. The aim of this study was to reveal the experiences of individual care workers performing oral care for dementia patients. The oral health of the elderly is in a critical state and in most cases not enough attention is paid to this problem. Material and methods: A qualitative research method was chosen for the research. The data collection instrument was a semi-structured interview, the purpose of which was to reveal the experience, knowledge, and attitude of individual care workers towards the importance of oral care and the oral hygiene habits of patients with dementia. The number of research informants was 10. The inclusion criteria were individual care workers working in social care institutions who were responsible for the personal care of dementia patients. Results: The analysis of the study showed that the main obstacles facing individual care workers in performing oral care for dementia patients are related to their cognitive disorders. For this reason, unreasonable fears of patients may arise, which also affect the proper performance of individual oral hygiene and other tasks assigned to employees. Conclusions: The results of the study showed that according the informants' opinions it is crucial to take care of dementia patients' oral care daily.

Effect of Honey-based Oral Care on Oral Health of Patients With Stroke Undergoing Rehabilitation: A Randomized Controlled Trial.

PURPOSE: To investigate the effects of honey-based oral care on the oral health of patients with stroke undergoing rehabilitation. METHODS: In this randomized controlled trial, 44 stroke patients from a tertiary hospital's rehabilitation ward were assigned to receive either honey-based oral care or normal saline, with treatments administered twice daily for 2 weeks. The study, conducted from November 2021 to August 2022, employed a double-blind method, blinding both participants and evaluators to treatment allocations. The key outcomes measured included oral status, dental plaque index (DPI), and xerostomia. The final analysis included 13 patients in the experimental group and 16 in the control group. RESULTS: The intervention significantly changed the oral status, DPI, and xerostomia between the groups. The experimental group showed significantly improved oral status (Z = -4.63, p < .001), DPI (Z = -4.58, p < .001), and xerostomia (t = -6.33, p < .001) compared with the control group. The experimental group showed significant improvements in oral status (Z = -3.27, p = .001), DPI (Z = -3.19, p = .001), and xerostomia (t = 7.37, p < .001) after the intervention, confirming the efficacy of honey-based oral care. CONCLUSIONS: Honey-based oral care effectively improves oral status and xerostomia, and reduces DPI in patients with stroke. CLINICAL TRIAL REGISTRATION NUMBER: Clinical Research Information Service, KCT0008201. Registered on 04 February 2023. The first patient was enrolled on November 16, 2021, at https://cris.nih.go.kr/cris/search/listDetail.do?searchWord=KCT0008201&search_yn=Y.

Pilot, open-label, randomized controlled clinical trial evaluating 4 oral hygiene regimens using a manual toothbrush, toothpaste, and mouthwash.

In this prospective pilot study, 84 patients with a history of poor oral hygiene were enrolled in an open-label, interventional, randomized controlled clinical trial. The aim was to provide preliminary clinical data on a new line of oral hygiene products containing a prebiotic and a paraprobiotic based on Lactobacillus plantarum. The recruitment rate and patient satisfaction were analyzed to estimate resources for the future primary study, and descriptive data on rebalancing of the oral microbiota were collected. The population was divided into 5 groups based on the products assigned to the patients: 1, delicate mint toothpaste (n = 20); 2, mint toothpaste (n = 12); 3, mint mouthwash (n = 20); 4, delicate mint toothpaste, mint mouthwash, and an antimicrobial toothbrush (n = 20); and 5, continued use of their usual oral care products and routine (control group; n = 12). The study duration was 28 days. All patients tolerated the products well, and there were no adverse events. The recruitment capability and procedures allowed for a realistic estimation for the future main trial. The products did not cause any changes in tooth color. The participants in group 4, who completed the treatment consisting of delicate mint toothpaste, mint mouthwash, and an antimicrobial toothbrush, reported the greatest reduction in gingival sensitivity (P ≤ 0.000; Wilcoxon signed rank test). Analysis with the Wilcoxon signed rank test revealed that all products induced a statistically significant decrease in plaque (P ≤ 0.002) and a reduction in gingival sensitivity (delicate mint toothpaste, P ≤ 0.005; mint toothpaste, P ≤ 0.015; and mint mouthwash, P ≤ 0.015). All products were effective in stabilizing the oral microbiota. The tested products showed an optimal safety profile and a statistically significant efficacy in reducing gingival sensitivity and plaque. They also stabilized the biodiversity of the oral microbiota, making it less susceptible to microbial fluctuations than the control group. Trial registration: ClinicalTrials.gov (NCT05999175).

Comparison of the effect of licorice and chlorhexidine mouthwash on the oral health of intubated patients in the intensive care unit.

BACKGROUND: Chlorhexidine mouthwash is a common oral hygiene product used in intensive care units, but it may have some adverse effects. Licorice, a natural herb, could be a potential alternative to chlorhexidine. However, the effect of licorice mouthwash on the oral health of intubated patients has not been studied yet. Therefore, this study aimed to compare the effects of licorice and chlorhexidine mouthwash on the oral health of intubated patients. METHODS: This was a triple-blind clinical trial. The sample included 130 intubated patients admitted to an intensive care unit in Iran. The samples were selected by convenience sampling and randomly assigned to two groups: A and B. In group A, the main researcher applied 15 ml of 0.2% chlorhexidine mouthwash after each brushing (twice a day for 5.5 days) and suctioned it after 30 s. In group B, 20% licorice mouthwash was used instead of chlorhexidine. The demographic information questionnaire and the Beck Oral Assessment Scale (BOAS) were completed by one of the nurses before and on the sixth day of the study. RESULTS: Finally, 60 patients in each group completed the study. There was no significant difference between the groups in terms of demographic variables or oral health before the intervention (P > 0.05). The oral health of patients in both the chlorhexidine and liquorice mouthwash groups improved significantly after the intervention (P < 0.05). However, there was no significant difference in oral health between the two groups at postintervention (P = 0.06). CONCLUSION: The results demonstrated that both mouthwashes exerted a comparable effect on dental and oral health. However, the chlorhexidine mouthwash showed a greater impact on the reduction of dental plaque and the thinning of saliva compared to licorice mouthwash. In essential cases, licorice mouthwash can be employed as an alternative to chlorhexidine.

Can traditional oral hygiene methods compete with conventional toothbrushes in effectiveness?

DESIGN: The study was designed as a single-blinded, parallel, randomized controlled trial to compare the effectiveness of the Salvadora persica toothbrush (MTB), Salvadora persica chewing stick (MCS), and a standard toothbrush (STB) in controlling plaque and gingivitis. A total of 78 participants were randomly divided into three groups and instructed to use their assigned oral hygiene tool in a standardized manner for three. CASE SELECTION: Participants were non-dental students and staff of Universiti Kebangsaan Malaysia, Kuala Lumpur Campus, selected through convenience sampling. They met specific inclusion criteria, such as being systemically healthy, having ≥20 teeth, and having a Basic Periodontal Examination score of 0, 1, or 2, with no periodontal pockets greater than 5.5 mm. DATA ANALYSIS: Clinical outcomes were measured using the Plaque Index (PI) and Periodontal Inflamed Surface Area (PISA) at baseline, one-, and three-weeks post-intervention. Data analysis was performed using mixed-model analysis of variance for continuous variables and Fisher's exact test for categorical variables. RESULTS: All three groups showed significant improvements in plaque levels and severity of gingivitis from baseline to three weeks post-intervention. The MCS group demonstrated a significant improvement in mean PISA values of the anterior teeth compared to the MTB and STB groups. However, there was no significant difference in plaque level reduction or overall gingivitis severity among the three groups. This indicates that when used correctly, Salvadora persica toothbrushes and chewing sticks are as effective as standard toothbrushes in plaque control and gingival health. CONCLUSIONS: The study concludes that both Salvadora persica toothbrushes and chewing sticks can serve as effective alternatives to the standard toothbrush for plaque control and gingival health. This showcases the beneficial anti-plaque and anti-gingivitis properties of Salvadora persica. However, the effectiveness of these oral hygiene tools is contingent upon the correct usage techniques.

Oral Irrigation Devices: A Scoping Review.

OBJECTIVES: Self-performed oral hygiene is essential for preventing dental caries, periodontal, and peri-implant diseases. Oral irrigators are adjunctive oral home care aids that may benefit oral health. However, the effects of oral irrigation on oral health, its role in oral home care, and its mechanism of action are not fully understood. A comprehensive search of the literature revealed no existing broad scoping reviews on oral irrigators. Therefore, this study aimed to provide a comprehensive systematic review of the literature on oral irrigation devices and identify evidence gaps. METHODS: The Joanna Briggs Institute and Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews guidelines were utilized to prepare the review. Four databases and eight gray literature sources were searched for English publications across any geographical location or setting. RESULTS: Two hundred and seventy-five sources were included, predominantly from scientific journals and academic settings. Most studies originated from North America. Research primarily involved adults, with limited studies in children and adolescents. Oral irrigation was safe and well-accepted when used appropriately. It reduced periodontal inflammation, potentially by modulating the oral microbiota, but further research needs to clarify its mechanism of action. Promising results were reported in populations with dental implants and special needs. Patient acceptance appeared high, but standardized patient-reported outcome measures were rarely used. Anti-inflammatory benefits occurred consistently across populations and irrigant solutions. Plaque reduction findings were mixed, potentially reflecting differences in study designs and devices. CONCLUSIONS: Oral irrigators reduce periodontal inflammation, but their impact on plaque removal remains unclear. Well-designed, sufficiently powered trials of appropriate duration need to assess the clinical, microbiological, and inflammatory responses of the periodontium to oral irrigation, particularly those with periodontitis, dental implants, and special needs. Patient-reported outcome measures, costs, caries prevention, and environmental impact of oral irrigation need to be compared to other oral hygiene aids.

Formulation and assessment of biological properties of garcinia indica fruit extract mouthrinse as an adjunct to oral hygiene regimen: an in vitro analysis.

The prevalence of gingivitis is substantial within the general population, necessitating rigorous oral hygiene maintenance. OBJECTIVE: This study assessed a Garcinia indica (GI) fruit extract-based mouthrinse, comparing it to a 0.1% turmeric mouthrinse and a 0.2% Chlorhexidine (CHX) mouthrinse. The evaluation encompassed substantivity, staining potential, antimicrobial efficacy and cytocompatibility. METHODOLOGY: The study employed 182 tooth sections. For antimicrobial analysis, 64 extracted human teeth coated with a polymicrobial biofilm were divided into four groups, each receiving an experimental mouthrinse or serving as a control group with distilled water. Microbial reduction was assessed through colony forming units (CFU). Substantivity was evaluated on 54 human tooth sections using a UV spectrophotometer, while staining potential was examined on 64 tooth sections. Cytocompatibility was tested using colorimetric assay to determine non-toxic levels of 0.2% GI fruit extract, 0.1% Turmeric, and 0.2% CHX. RESULTS: Data were analysed with one-way ANOVA (α=0.05). Cell viability was highly significant (p<0.001) in the 0.2% GI group (64.1±0.29) compared to 0.1% Turmeric (40.2±0.34) and 0.2% CHX (10.95±1.40). For antimicrobial activity, both 0.2% GI (20.18±4.81) and 0.2% CHX (28.22±5.41) exhibited no significant difference (P>0.05) at end of 12 hours. However, 0.1% Turmeric showed minimal CFU reduction (P<0.001). Substantivity results at 360 minutes indicated statistically significant higher mean release rate in 0.1%Turmeric (12.47±5.84 ) when compared to 0.2% GI (5.02±3.04) and 0.2% CHX (4.13±2.25) (p<0.001). The overall discoloration changes (∆E) were more prominent in the 0.2% CHX group (18.65±8.3) compared to 0.2% GI (7.61±2.4) and 0.1% Turmeric (7.32±4.9) (P<0.001). CONCLUSION: This study supports 0.2% GI and 0.1% Turmeric mouth rinses as potential natural alternatives to chemical mouth rinses. These findings highlight viability of these natural supplements in oral healthcare.
