A Holistic Approach for Ethics and Sustainability in the Food Chain: The Gateway to Oral and Systemic Health

Food production is a complex matter, affecting people's lives, organizations' profits, and the well-being of the whole planet, and has multifaceted ethical considerations surrounding its production, distribution, and consumption. This paper addresses the pressing need to confront ethical challenges within the food system, encompassing issues such as environmental sustainability, food security, and individual food choices for better oral and systemic health of all individuals around the globe. From agricultural practices to global trade and food waste, ethical implications are addressed across various domains, highlighting the interconnectedness of ethical decision-making in the food industry. Central themes explored include the ethical dimensions of food production methods, the impact of global trade on food ethics, and the role of individuals in making ethically informed food choices. Additionally, this paper considers the spiritual and physical significance of food, particularly through the lens of oral health as a gateway to holistic well-being. Recognizing the complexity of the food and mouth ecosystem, this paper calls for serious interventions in legislation and economics to promote ethical protocols and techniques for sustainability reasons. It emphasizes the importance of ethical considerations in food safety management systems, regulatory frameworks, and quality standards. Moreover, this paper underlines the need for a comprehensive approach to address ethical dilemmas and moral values inherent in the food industry and oral health policies, adopting the precautionary principle and ethical decision-making frameworks. This article finally aims to serve as a call to action for stakeholders across the food industry and the healthcare sector, to prioritize ethical practices, promote transparency, rearrange economic parameters, and work towards a more sustainable and equitable food system for inner and outer oral and systemic health and human sustainability for all.

Heterogeneous Association of Tooth Loss with Functional Limitations

Tooth loss is prevalent in older adults and associated with functional capacity decline. Studies on the susceptibility of some individuals to the effects of tooth loss are lacking. This study aimed to investigate the heterogeneity of the association between tooth loss and higher-level functional capacity in older Japanese individuals employing a machine learning approach. This is a prospective cohort study using the data of adults aged ≥65 y in Japan (N = 16,553). Higher-level functional capacity, comprising instrumental independence, intellectual activity, and social role, was evaluated using the Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-IC). The scale ranged from 0 (lowest function) to 13 (highest function). Doubly robust targeted maximum likelihood estimation was used to estimate the population-average association between tooth loss (having <20 natural teeth) and TMIG-IC total score after 6 y. The heterogeneity of the association was evaluated by estimating conditional average treatment effects (CATEs) using the causal forest algorithm. The result showed that tooth loss was statistically significantly associated with lower TMIG-IC total scores (population-average effect: -0.14; 95% confidence interval, -0.18 to -0.09). The causal forest analysis revealed the heterogeneous associations between tooth loss and lower TMIG-IC total score after 6 y (median of estimated CATEs = -0.13; interquartile range = 0.12). The high-impact subgroup (i.e., individuals with estimated CATEs of the bottom 10%) were significantly more likely to be older and male, had a lower socioeconomic status, did not have a partner, and had poor health conditions compared with the low-impact subgroup (i.e., individuals with estimated CATEs of the top 10%). This study found that heterogeneity exists in the association between tooth loss and lower scores on functional capacity. Implementing tooth loss prevention policy and clinical measures, especially among vulnerable subpopulations significantly affected by tooth loss, may reduce its burden more effectively.

The All-on-4 Concept Using Polyetheretherketone (PEEK)-Acrylic Resin Prostheses: Follow-Up Results of the Development Group at 5 Years and the Routine Group at One Year

BACKGROUND

It is necessary to investigate the application of polymer materials in implant dentistry. The aim of this study was to examine the outcome of full-arch polyetheretherketone (PEEK)-acrylic resin implant-supported prostheses.

METHODS

Seventy-six patients were rehabilitated consecutively with 100 full-arch implant-supported prostheses of PEEK-acrylic resin (a development group (DG): 37 patients with 5 years of follow-up; a routine group (RG): 39 patients with 1 year of follow-up). The primary outcome measure was prosthetic survival. Secondary outcome measures were implant survival, marginal bone loss, biological complications, prosthetic complications, veneer adhesion, plaque levels, bleeding levels, and a patient subjective evaluation (including the Oral Health Impact Profile for the RG).

RESULTS

In both groups, prosthetic (DG: 93.6%; RG: 100%) and implant survival (DG: 98.9%; RG: 99.5%) were high, and marginal bone loss was low (DG: 0.54 mm; RG: 0.28 mm). The veneer adhesion rate was 28.6% of prostheses in DG (RG = 0%). Mechanical complications occurred in 49% and 11.8% of prostheses in DG and RG, respectively. Biological complications, plaque, and bleeding levels were low in both groups. The subjective patient evaluation was excellent in both groups (8.6 < DG < 8.8; 9.3 < RG < 9.5; OHIP = 1.38).

CONCLUSIONS

Within the limitations of this study, PEEK can be considered a viable prosthetic alternative.

Using machine learning to study the association of sociodemographic indicators, biomarkers, and oral condition in older adults in Colombia

BACKGROUND

Chronic health conditions and socioeconomic problems that affect the well-being and life expectancy of older adults are common. The objective of this cross-sectional study was to analyze the association between sociodemographic variables, oral conditions, and general health and the biomarkers of older adults using machine learning (ML).

METHODS

A total of 15,068 surveys from the national study of Health, Well-Being and Aging (Salud, Bienestar y Envejecimiento) data set were used for this secondary analysis. Of these, 3,128 people provided blood samples for the analysis of blood biomarkers. Sociodemographic, oral health, and general health variables were analyzed using ML and logistic regression.

RESULTS

The results of clustering analysis showed that dyslipidemia was associated with poor oral condition, lower socioeconomic status, being female, and low education. The self-perception of oral health in older adults was not associated with the presence of teeth, blood biomarkers, or socioeconomic variables. However, the necessity of replacing a dental prosthesis was associated with the lowest self-perception of oral health. Edentulism was associated with being female, increased age, and smoking.

CONCLUSIONS

Socioeconomic and educational disparities, sex, and smoking are important factors for tooth loss and suboptimal blood biomarkers in older adults. ML is a powerful tool for identifying potential variables that may aid in the prevention of systemic and oral diseases in older adults, which would improve geriatric dentistry.

PRACTICAL IMPLICATIONS

These findings can help the academic community identify critical sociodemographic and clinical factors that influence the process of healthy aging and serve as a useful guide to enhance health care policies and geriatric oral health care services.

Unraveling the signs and symptoms of oral conditions that affect daily life activities and oral health-related quality of life

OBJECTIVES

Since oral conditions negatively affect oral health-related quality of life (OHRQoL), this study evaluated which oral clinical condition, signs, and symptoms are associated with the impact on OHRQoL, its domains, and specific daily life activities among adults.

MATERIALS AND METHODS

Data from a probabilistic sample of adults (35-44 years old) was used. The Oral Impacts on Daily Performance (OIDP) was used to evaluate OHRQoL, its domains (physical, psychological, and social), and nine daily life activities. Signs and symptoms of oral diseases (dental caries, periodontal disease, need for dental prothesis, and tooth loss) and oral self-perception were considered. Descriptive, bivariate, and multi-level analyses were conducted.

RESULTS

A total of 5,834 adults were included, of which 52.9% had some negative impact of oral conditions on OHRQoL. Difficulty in eating was the most affected daily life activity. For multiple models, dental caries lesions (cavities), filled teeth with caries, gingival bleeding, periodontal pocket, dental pain, need for upper or lower dental prosthesis, and oral health self-perception were associated (p < 0.05) with overall OHRQoL or at least one of its domains. The impact on daily life activities of each individual was associated with at least one oral condition. Dental caries lesions (cavity) and dental pain were associated (p < 0.05) with the impact on most daily life activities evaluated.

CONCLUSIONS

Different signs and symptoms of prevalent oral diseases are associated with the impact on specific daily life activities among adults, which may compromise the OHRQoL.

CLINICAL RELEVANCE

Knowledge of how signs, symptoms, and oral conditions affect OHRQoL and daily life activities can provide essential information for clinicians to establish proper disease management and preventive strategies focusing on improving patients' lives.

The impact of dental care programs on healthcare system and societal outcomes: a scoping review

BACKGROUND

Dental diseases have detrimental effects on healthcare systems and societies at large. Providing access to dental care can arguably improve health outcomes, reduce healthcare utilization costs, and improve several societal outcomes.

OBJECTIVES

Our objective was to review the literature to assess the impacts of dental care programs on healthcare and societal outcomes. Specifically, to identify the nature of such programs, including the type of services delivered, who was targeted, where services were delivered, and how access to dental care was enabled. Also, what kind of societal and healthcare outcomes have been attempted to be addressed through these programs were identified.

METHODS

We conducted a scoping review by searching four databases, MEDLINE, EMBASE, CINAHL, and Sociological Abstracts. Relevant articles published in English language from January 2000 to February 2022 were screened by four reviewers to determine eligibility for inclusion.

RESULTS

The search resulted in 29,468 original articles, of which 25 were included in the data synthesis. We found minimal evidence that answers our proposed research question. The majority of identified programs have demonstrated effectiveness in reducing medical and dental healthcare utilization (especially for non-preventive services) and avert more invasive treatments, and to a lesser degree, resulting in cost-savings. Moreover, some promising but limited evidence about program impacts on societal outcomes such as reducing homelessness and improving employability was reported.

CONCLUSION

Despite the well-known societal and economic consequences of dental problem, there is a paucity of studies that address the impacts of dental care programs from the societal and healthcare system perspectives.

Oral health is Essential to the Well-Being of Older People

Although the highest attainable standard of health is a fundamental human right, oral health is often not considered an important component of overall health. Older people experience poorer quality of life due to discomfort and uncleanliness of their mouth and there continue to be barriers within health systems that contribute to this poor oral health. This paper advocates for oral health to be considered part of the basic human right to good health care and discusses how stakeholders can collaborate and work together to begin to meet the needs of this population, proposing solutions and recommendations to bring about change.

Assessment of global health programs at accredited dental schools in the United States

PURPOSE

Oral diseases pose a serious global health challenge. As such, dental education must integrate global health with emphasis on scalable and sustainable solutions. The aim of our study was to capture the scope of global health programs offered to dental students in the United States and identify ways in which dental schools may modify their curricula to improve global health knowledge and accessibility for students.

MATERIALS AND METHODS

For this cross-sectional, cohort study, the investigators sent a confidential and electronic survey to 213 faculty members at the 67 accredited dental schools in the United States. This voluntary survey was distributed in September and October of 2020 with answers being self-reported.

RESULTS

A total of 40 different schools are represented in this study, representing 59.7% of accredited dental schools in the United States. Using descriptive statistics, the results present existing global health opportunities, barriers preventing schools from expanding global health education, and necessary resources that schools without a program need to establish one.

CONCLUSION

Our results demonstrate promising findings, in relation to global health being a vital part of dental education. However, there is an urgent need for enhanced and more structured education in this space. As the global burden of oral disease contributes to the degree and severity of noncommunicable diseases worldwide, the development of a sustainable, preventive primary care approach must integrate oral health, making future dental professionals a crucial component of global health.

Age period cohort analysis of chewing ability in Korea from 2007 to 2018

There have been marked improvements in oral health in Korea during the past 10 years, including chewing ability. We sought to disentangle age, period, and cohort effects in chewing ability between 2007 and 2018. We analyzed data from the Korea National Health and Nutrition Examination Survey. The main variable was chewing difficulty, which was assessed among participants aged 20 years and older. APC analysis revealed three trends in chewing difficulty: (1) there was an increase in chewing difficulty starting at around 60 years of age (age effect), (2) there was a steady decrease in chewing difficulty during the observation period (period effect), and (3) chewing ability improved with each successive generation born after 1951 (cohort effect). Regarding recent improvements in chewing ability, cohort effects were somewhat more important than period effects.

Orale Erkrankungen sind ein signifikantes globales Gesundheitsproblem über alle Länder und Bevölkerungsgruppen hinweg. Mit fast 3,5 Mrd. Erkrankungsfällen (2017) sind so viele Menschen betroffen wie von keiner anderen Krankheitsgruppe. Die Haupterkrankungen sind unbehandelte Karies der bleibenden oder der Milchzähne, fortgeschrittene Parodontopathien, Zahnlosigkeit sowie Karzinome der Mundhöhle und Lippen. Bei weitgehend unverändert hoher globaler Prävalenz erhöhen durch Bevölkerungswachstum bedingte stark steigende Fallzahlen den Druck auf schwache oder überlastete Gesundheitssysteme, insbesondere in Ländern der unteren und mittleren Einkommensgruppen.

Dennoch wird der Mundgesundheit in vielen Ländern nur unzureichende Priorität eingeräumt und sie erhält als wichtiges Thema im gesundheitspolitischen Diskurs der deutschen und globalen Akteure nach wie vor wenig Aufmerksamkeit. Eine der fundamentalen Herausforderungen ist dabei die Gewährleistung eines allgemeinen und fairen Zugangs zu adäquater universeller Basisgesundheitsversorgung für alle Menschen ohne Verursachung von finanziellen Härten (Universal Health Coverage).

Dieser Beitrag gibt einen einführenden Überblick über die globalen Trends der weltweiten Krankheitslast der oralen Haupterkrankungen, die von starken Ungleichheiten geprägt sind. Verbesserungsansätze aus der bevölkerungsweiten Risikoreduktion und Prävention, der Versorgungsplanung sowie gesundheitspolitische Lösungen werden kurz vorgestellt. Dabei werden die im internationalen Diskurs wichtigen Themen angesprochen und die im Rahmen einer Lancet-Artikelserie zur globalen Mundgesundheit aus dem Jahr 2019 entwickelten Reformbereiche besprochen. Schließlich werden neue Initiativen diskutiert sowie Empfehlungen für die deutsche und internationale gesundheitliche Entwicklungspolitik gegeben, die in den kommenden Jahren die Situation der globalen Mundgesundheit entscheidend verbessern könnten.

Edentulism-free life expectancy among older Brazilian adults: SABE study, 2006-2016

AIM

To assess edentulism-free life expectancy (EFLE) and the related inequalities by sex and schooling among older Brazilian adults from 2006 to 2016.

BACKGROUND

Tooth loss is related to shortened longevity and unhealthy life expectancy in old age.

MATERIALS AND METHODS

The outcome of the study was EFLE, assessed by age, sex and schooling. EFLE was estimated using the Sullivan method, considering the years and proportion of remaining life and the prevalence of edentulism-assessed in the Health, Well-being, and Aging cohort study, as well as the official mortality data for adults aged 60 years or older living in São Paulo, Brazil.

RESULTS

EFLE increased from 10.9 (95% CI: 10.4-11.5) to 13.8 (95% CI: 13.2-14.5) years, considering data from 2006 to 2016, among 60-year-old individuals. In relative terms, these individuals expected to live 50.7% (95% CI: 48.1-53.2) of their remaining life free of edentulism in 2006, while this expectation was 62.8% (95% CI: 60.0-65.6) in 2016. Within both years, women and the less educated had lower EFLE than men and the higher educated.

CONCLUSION

EFLE increased from 2006 to 2016. However, inequalities concerning sex and education remained significant, thereby highlighting the need to continuously address inequalities in tooth loss throughout life to contribute to a healthy ageing.

Causal Effect of Tooth Loss on Functional Capacity in Older Adults in England: A Natural Experiment

BACKGROUND/OBJECTIVES

Tooth loss is associated with reduced functional capacity, but so far, there is no relevant causal evidence reported. We investigated the causal effect of tooth loss on the instrumental activities of daily living (IADL) among older adults in England.

DESIGN

Natural experiment study with instrumental variable analysis.

SETTING

The English Longitudinal Study of Aging (ELSA) combined with the participants' childhood exposure to water fluoride due to the community water fluoridation.

PARTICIPANTS

Five thousand six hundred and thirty one adults in England born in 1945-1965 participated in the ELSA wave seven survey (conducted in 2014-2015; average age: 61.0 years, 44.6% men).

MEASUREMENTS

The number of natural teeth predicted by the exogenous geographical and historical variation in exposure to water fluoride from age 5 to 20 years old (instrumental variable) was used as an exposure variable. The outcome, having any limitations in IADL (preparing a hot meal, shopping for groceries, making telephone calls, taking medications, doing work around the house or garden, or managing money), was assessed by self-reported questionnaires.

RESULTS

Linear probability model with Two-Stage Least Squares estimation was fitted. Being exposed to fluoridated water was associated with having more natural teeth in later life (coefficient: 0.726; 95% confidence interval (CI) = 0.311, 1.142; F = 11.749). Retaining one more natural tooth reduced the probability of having a limitation in IADL by 3.1 percentage points (coefficient: -0.031; 95% CI = -0.060, -0.002).

CONCLUSION

Preventing tooth loss maintains functional capacity among older adults in England. Given the high prevalence of tooth loss, this effect is considerable. Further research on the mechanism of the observed causal relationship is needed.

Front-of-Package Food Labeling to Reduce Caries: Economic Evaluation

Front-of-package food labeling (FoPFL) is increasingly advocated as an effective intervention to facilitate behavior changes toward healthier food purchasing and consumption, particularly in relation to products with added sugar. The present study assessed the potential caries-related impacts of FoPFL, using Germany as an example. The outcomes of interest were caries lesions prevented, dental treatment costs avoided, productivity loss reductions, and disability-adjusted life years (DALYs) averted. The baseline consumption of added sugar was derived from the German National Nutrition Survey. The reduction in sugar intake due to FoPFL was modeled according to estimates from a recent meta-analysis. Microsimulations were performed for 500,000 individuals and over a time horizon of 10 y. Deterministic and probabilistic sensitivity analyses were performed to check the robustness of results. For the period from 2017 to 2027, FoPFL was identified to prevent 2,370,715 (95% confidence interval [CI], 2,062,730-2,678,700) caries lesions and avert 677.62 (95% CI, 589.59-765.65) DALYs. Treatment cost savings amounted to €175.67 million (95% CI, €152.85-€198.49), and productivity losses reduced by €27.33 million (95% CI, €23.78-€30.88). Sensitivity analyses showed that the magnitude of the effects is highly dependent on consumers' response to FoPFL. Our findings suggest that FoPFL has the potential to substantially reduce caries increment, caries-related morbidity, and economic burden. In addition, our study allows for the inclusion of oral health estimates in overall health estimates for sugar-related food labeling. Before prioritizing a strategy to tackle sugar consumption, decision makers should carefully consider all relevant context-specific factors and implementation costs.

Contextual and individual determinants of the need for endodontic treatment in adults in Brazil: A multilevel analysis

AIM

To examine the relationship between contextual and individual determinants with the need for endodontic treatment in Brazilian adults.

METHODS

Individual-level data from 6897 adults aged 35-44 years living in the Brazilian state capitals who participated in the Brazilian Oral Health Survey (SBBrasil 2010 Project) were combined with city-level data. Individual- and city-level variables were selected to represent the structural and intermediate determinants of health according to the WHO model of social determinants of health. The association of independent variables with one or more teeth in need of endodontic treatment was evaluated using multilevel logistic regression to estimate the odds ratio (OR) and 95% confidence intervals (CI).

RESULTS

The prevalence of the need for endodontic treatment was 7.7%. Adults living in cities with better contextual socioeconomic conditions (OR 0.82; 95% CI = 0.72-0.93) and better specialized dental services (OR 0.85; 95% CI = 0.77-0.95) were less likely to need endodontic treatment. Younger age, greater schooling and use of private dental services reduced the odds of need for endodontic treatment. Number of people per room, type of dental service and reason for the last dental visit were also associated with need of endodontic treatment.

CONCLUSION

Contextual and individual factors were relevant determinants of endodontic treatment needs in adults.

GWAS of Post-Orthodontic Aggressive External Apical Root Resorption Identified Multiple Putative Loci at X-Y Chromosomes

Personalized dental medicine requires from precise and customized genomic diagnostic. To conduct an association analysis over multiple putative loci and genes located at chromosomes 2, 4, 8, 12, 18, X, and Y, potentially implicated in an extreme type of external apical root resorption secondary to orthodontic forces (aEARR). A genome-wide association study of aEARR was conducted with 480 patients [ratio~1:3 case/control]. Genomic DNA was extracted and analyzed using the high-throughput Axiom platform with the GeneTitan^® MC Instrument. Up to 14,377 single nucleotide polymorphisms (SNPs) were selected at candidate regions and clinical/diagnostic data were recorded. A descriptive analysis of the data along with a backward conditional binary logistic regression was used to calculate odds ratios, with 95% confidence intervals [p < 0.05]. To select the best SNP candidates, a logistic regression model was fitted assuming a log-additive genetic model using R software [p < 0.0001]. In this sample the top lead genetic variants associated with aEARR were two novel putative genes located in the X chromosome, specifically, STAG 2 gene, rs151184635 and RP1-30E17.2 gene, rs55839915. These variants were found to be associated with an increased risk of aEARR, particularly restricted to men [OR: 6.09; 95%CI: 2.6–14.23 and OR: 6.86; 95%CI: 2.65–17.81, respectively]. Marginal associations were found at previously studied variants such as SSP1: rs11730582 [OR: 0.54; 95%CI: 0.34–0.86; p = 0.008], P2RX7: rs1718119 [OR: 0.6; 95%CI: 0.36–1.01; p = 0.047], and TNFRSF11A: rs8086340 [OR: 0.6; 95%CI: 0.38–0.95; p = 0.024]), found solely in females. Multiple putative genetic variants located at chromosomes X and Y are potentially implicated in an extreme phenotype of aEARR. A gender-linked association was noted.

Estimating Lifetime Dental Care Expenditure in South Korea: An Abridged Life Table Approach

The aim of this study was to measure the magnitude and distribution of a Korean’s lifetime dental expenses depending on age and sex, by constructing a hypothetical lifetime and life table of survival. Additionally, we estimated the difference in life expectancy between men and women and its impact on dental expenses. We used the 2015 Korea Health Panel Survey to calculate the total dental expenditure, including expenses paid directly by patients and those paid by insurers. We generated survival profiles to simulate dental expenses during a typical lifetime (from birth to age 95) using the abridged life table (five-year intervals for age groups) in 2015 from the South Korean Statistical Information Service. We independently calculated the remaining dental expenses for survivors of all ages. The results showed that an estimate of average lifetime dental expenditure was $31,851 per capita: $31,587 for men and $32,318 for women. Nearly 33% of the average per capita lifetime dental expenditure was attributable to the longer life expectancy of women, with no statistically significant difference in lifetime dental expenditure between men and women. Many survivors incurred 70% of their lifetime dental expenses before age 65. The results highlighted the need for policymakers to address spending on age-specific dental care owing to extended life expectancy, given the disproportionate share of healthcare resources supporting the elderly.

Life expectancy with negative physical oral health impact on quality of life in older adults

Abstract: Oral impairments can affect overall health and life expectancy in older adults. Our study evaluates the life expectancy with negative physical oral health impact on quality of life (POHIQoL) among older adults. Life expectancy with negative POHIQoL was estimated by the Sullivan method, using the prevalence of POHIQoL - obtained in the Health, Well-being and Ageing (SABE Study); and official mortality data for adults aged 60 years or older living in São Paulo, Brazil. Between 2000 and 2010, negative POHIQoL increased from 23.4% (95%CI: 20.2-26.9) to 30.4% (95%CI: 27.0-34.3) among older adults; total life expectancy increased from 22 and 17.5 to 23.7 and 19.4 years among 60-year-old women and men, respectively; and the proportion of remaining years to be lived with negative POHIQoL increased from 25.1% to 32.1% for the same age group. In both years, individuals aged 60 years with lower education level were expected to live more years with negative POHIQoL when compared with the most schooled ones (2000: 15.9 [95%CI: 15.0-16.8] vs. 14.3 [95%CI: 13.7-14.8]; 2010: 16.3 [95%CI: 15.1-17.4] vs. 14.1 [95%CI: 13.2-15.1]). Similarly, women were expected to live more years with negative POHIQoL than men. Within ten years, life expectancy with negative POHIQoL increased, as well as the existence of inequalities in sex and education level among Brazilian older adults. Expansion in coverage and focus on equity in dental care are still necessary to overcome persistent dental-related problems and inequalities and, therefore, contribute to healthy ageing.

The Prevention of Infections in Older Adults: Oral Health

The oral cavity is exposed to the external environment and from a very young age is colonized by infectious agents. Under certain circumstances including poor oral hygiene, dry mouth, trauma, and the use of antibiotics, oral infections can occur. They can result in damage to the oral cavity including teeth and their support structures. Oral infections can also lead to the extension of infection into surrounding tissues and to systemic infections. Chronic oral infection is a recognized risk factor for heart disease. Older adults are at high risk for oral infections and associated complications. Tooth loss, for which infection is the most significant cause, leads to cosmetic changes and a decreased ability to masticate certain foods that can lead to malnutrition. Chronic oral infections and the manipulation of teeth and supporting structures can lead to the hematogenous spread of infection including the infection of artificial joints and endocardial implants. Good oral hygiene, the use of fluoride, regular dental care, and the appropriate use of antibiotics can all reduce oral infections and their associated complications.
