Oral health of children with respiratory diseases

Oral health and related outcomes in children and adolescents with cystic fibrosis: a scoping review

PURPOSE

Good oral health is important for children and adolescents with cystic fibrosis (CF). The purpose of this scoping review is to describe the existing evidence base regarding oral health in children and adolescents with CF and provide recommendations for future research.

METHODS

Using a scoping review framework, a comprehensive search was undertaken using medline, embase, and PubMed. The search strategy included broad terms relating to CF, oral health, and children and adolescents and included only papers written in English.

RESULTS

61 articles were included. Topics investigated included dental caries, enamel defects, periodontal health, dental staining, oral health related quality of life, dental management, and dental development of children and adolescents with CF.

CONCLUSION

Dental outcomes of children and adolescents with CF differ from the healthy population. The current literature describing dental health in children and adolescents with CF includes predominately descriptive analyses. A shift to hypothesis-based studies to explore causal relationships that explain the differences in dental outcomes seen in the CF population offers an opportunity to better understand the problems faced by children and adolescents with CF. Research that actively engages stakeholders, including children and adolescents with CF and their families will enable evidence-based recommendations to improve their oral health.

Effects of dietary nitrate supplementation on oral health and associated markers of systemic health: a systematic review

Poor oral health can impact an individual's ability to eat and has been associated with an increased risk of non-communicable diseases. While the benefits of nitrate consumption on oral health were first proposed more than 20 years ago, no systematic review has been published examining effects of dietary nitrate on oral health. This systematic review investigated the effects of dietary nitrate on markers of oral health in vivo in randomized controlled trials (RCTs). Five databases (PubMed, The Cochrane Library, CINAHL, MEDLINE, and SPORTDiscus) were searched from inception until March 2023. Nine articles reporting data on 284 participants were included. Dietary nitrate was provided via beetroot juice in most studies. The duration of the interventions ranged from one day to six weeks. Dietary nitrate supplementation increased the relative abundance of several individual bacterial genera including Neisseria and Rothia. Dietary nitrate supplementation increased salivary pH and decreased salivary acidification following consumption of a sugar-sweetened beverage. Furthermore, dietary nitrate supplementation resulted in a decrease in the gingival inflammation index. The results of this systematic review suggest that dietary nitrate could represent a potential nutritional strategy to positively modify oral health by impacting the oral microbiome, altering salivary pH, and minimizing gingival inflammation.

The Link between Periodontal Disease and Asthma: How Do These Two Diseases Affect Each Other?

A growing body of evidence suggests that the effects of poor oral hygiene extend beyond the oral cavity and are associated with a variety of systemic diseases, including asthma. Asthma, which results in symptoms of cough, wheezing, and dyspnoea, and is characterized by airflow limitation with variability and (partial or complete) reversibility, is amongst the most prevalent respiratory diseases with approximately 262 million patients worldwide, and its prevalence and disease burden is on the increase. While asthma can occur at a young age, it can also develop later in life and affects a variety of age groups. Both of these diseases have a chronic course, and various researchers have suggested a link between the two. In this article, we aim to provide a literature review focusing on the association between the two diseases. The results demonstrate that medications (primarily, inhaler medicine), hypoxia induced by asthma, and the breathing behaviour of patients potentially trigger periodontal disease. In contrast, oral periodontopathogenic microorganisms and the inflammatory mediators produced by them may be involved in the onset and/or exacerbation of asthma. Common contributing factors, such as smoking, gastro-oesophageal reflux, and type-2 inflammation, should also be considered when evaluating the relationship between the two diseases.

Allergic rhinitis and dental caries: A systematic review

OBJECTIVE

Dental caries is one of the most common chronic diseases affecting millions of people globally. Some studies revealed the presence of bidirectional relationship between allergic rhinitis (AR) and oral diseases, with each disease having a potential impact on the other. In this study we aimed to systematically review the literature and analyze the available evidence regarding whether AR contributes to the development of dental caries.

METHODS

Three authors, members of the YO-IFOS rhinology study group, independently analyzed the data sources (Pubmed, the Cochrane Library, EMBASE, SciELO) for papers assessing the relationship between rhinitis and caries, in adult and pediatric patients.

RESULTS

Eight studies met the inclusion criteria (87612 participants). Six studies were performed in children. A total of three studies found an association between AR and dental caries. Only two studies had adjusted the measure of effect for potentially confounding variables. Regarding the quality of the selected studies according to the NICE classification, the most observed methodological limitations detected were: (1) the cross-sectional design of the included studies which could have introduced a simultaneity bias, and (2) not clearly reporting the inclusion and exclusion criteria.

CONCLUSION

This systematic review can neither confirm nor deny the presence of an association between AR and caries. Despite the evidence is very scarce to conclude a relationship between AR and caries, the option for examining patients with repetitive caries by an otolaryngologist and those with AR by odontologist should be considered, as these examinations do not possess any risk for the patient.

The perceived association of oral diseases and general pathology among doctors of different specialties

This study aimed to highlight the perceived associations between general and oral pathology, among clinicians of different specialties. Data was collected through a questionnaire with 22 questions, with single or multiple answers, to 88 dentists, general practitioners, or pediatricians. The majority of participants were women (89.8%), aged between 30 and 39 years (52.3%), with a professional experience mostly under 10 years (61.3%). Many doctors considered that there was an association between oral and general pathologies (39.8%). The most common general pathologies associated with oral pathology were digestive disorders (n=21, 23.9%), followed by cardiovascular, genetic, endocrine and metabolic, neuropsychiatric, respiratory, hematological, immunological, and oncological pathologies. Tooth decay was mainly found in patients with digestive, respiratory, or neuropsychiatric disorders, and periodontal disease was more common in patients with obstetric disorders. Diseases of the oral mucosa, such as canker sores and gingivostomatitis, were more common in patients with digestive pathology, endocrine and metabolic, or reproductive disorders. The study pointed out that physicians, regardless of their medical training, often observed a relatively rich general pathology associated with oral conditions. It is important to differentiate between primary and secondary oral pathology, associated with general pathology and medication, establishing a correct diagnosis of the disease and treatment according to general or oral diseases and their manifestations.

Risk factors for and prevention of caries and dental erosion in children and adolescents with asthma

There are many studies and reviews of the relationship between the asthma disease in young individuals on the one hand and caries and dental erosion on the other. The causes of caries and dental erosion might be related to the asthmatic drugs, low pH and the sweeteners that the inhaled drug contains and perhaps even the lifestyle of children and adolescents with asthma. The main focus of this review is therefore to describe various preventive strategies, based on long experience of preventive dental care in Sweden. Two fact boxes are presented, one on fluoride toothpaste as a population-based intervention for different ages and one on diet counselling in children and adolescents with asthma. The most important thing is to introduce fluoride toothpaste early in the child's life and that the parents brush the child's teeth twice a day, in the morning after breakfast and at night before bedtime, up to the age of 10. Moreover, a high-risk approach with an additional fluoride supply at home is presented, together with the application of fluoride varnish at the clinic. Regarding diet counselling, it is important to make sure that the child has regular meals during the day, maximum five to six times a day, to allow the teeth to rest between meals and restrict sweets and soft drinks to once a week. It is important to identify children and adolescents with asthma as early as possible and to refer them to a dental team for preventive treatment.

Immunoglobulin Y for Potential Diagnostic and Therapeutic Applications in Infectious Diseases

Antiviral, antibacterial, and antiparasitic drugs and vaccines are essential to maintaining the health of humans and animals. Yet, their production can be slow and expensive, and efficacy lost once pathogens mount resistance. Chicken immunoglobulin Y (IgY) is a highly conserved homolog of human immunoglobulin G (IgG) that has shown benefits and a favorable safety profile, primarily in animal models of human infectious diseases. IgY is fast-acting, easy to produce, and low cost. IgY antibodies can readily be generated in large quantities with minimal environmental harm or infrastructure investment by using egg-laying hens. We summarize a variety of IgY uses, focusing on their potential for the detection, prevention, and treatment of human and animal infections.

Oral health in asthmatic patients: a review : Asthma and its therapy may impact on oral health

Different drugs used to treat asthma, such as beta 2 agonists and inhaled steroids, may promote a higher risk of caries, dental erosion, periodontal disease and oral candidiasis. This article reviews the evidences of mechanisms involved in oral diseases in patients affected by asthma. The main mechanism involved is the reduction of salivary flow. Other mechanisms include: acid pH in oral cavity induced by inhaled drugs (particularly dry powder inhaled), lifestyle (bad oral hygiene and higher consumption of sweet and acidic drinks), gastroesophageal reflux, and the impairment of local immunity. In conclusion asthma is involved in the genesis of oral pathologies both directly and indirectly due to the effect of the drugs used to treat them. Other cofactors such as poor oral hygiene increase the risk of developing oral diseases in these patients. Preventive oral measures, therefore, should be part of a global care for patients suffering from asthma.

Association between asthma and periodontal disease: A systematic review and meta-analysis

BACKGROUND

The aim of this systematic review (SR) is to evaluate the association between asthma and periodontal disease.

METHODS

An electronic search without date or language restrictions was carried out in PubMed/MEDLINE, Cochrane Central Register of Controlled Trials, Web of Science, and LILACS until May 2016. In addition, manual searches and searches of the gray literature were conducted. The search process, data analysis, and quality assessment were performed by two independent reviewing authors. Eligibility criteria included prospective and retrospective cohort studies, case-controls, and randomized clinical trials.

RESULTS

The search and selection process yielded 21 studies, published between 1979 and 2017. The meta-analysis showed a statistically significant difference for the parameters of gingival bleeding, plaque index, and gingival index for participants with asthma (P < 0.001).

CONCLUSION

Data from this SR strongly suggest the association of asthma with periodontal disease.

Are Down syndrome children more vulnerable to tooth wear?

BACKGROUND

An oral condition that has largely been ignored in the Down syndrome population is pathological tooth wear. This study is aimed to create more awareness of the reasons underlying the tooth wear observed in patients with Down syndrome and to suggest different methods to prevent this condition. This research also potentially serves as a platform for future researchers to perform an in-depth analysis of the factors we identified. The aim of this study was to determine if children with Down syndrome are more prone to tooth wear than children who do not have Down syndrome.

METHODS

Our sample consisted of 120 children with Down syndrome who were compared with 120 children with no disabilities. The parents or guardians were asked to complete a questionnaire and a 3-day diet chart, while the wear on each tooth was recorded using the standardised Simplified Smith and Knight Tooth Wear Index.

RESULTS

Children with Down syndrome experience tooth wear more frequently than non-Down syndrome children. A history of asthma, mouth breathing and gastro-oesophageal reflux disease as well as the intake of acidic diet and drinks has exerted significant effects on the prevalence of tooth wear.

CONCLUSIONS

The early diagnosis and analysis of the underlying aetiology are important for the management of tooth wear in children with Down syndrome who have shown a greater tendency to develop erosive lesions.

Is using nanosilver mattresses/pillows safe? A review of potential health implications of silver nanoparticles on human health

Human exposure to engineered nanoparticles has become inevitable in today's extensive commercial use and large-scale production of engineered nanoparticles. Even though several studies have characterised the exposure to nanomaterials during wakeful state (related to occupational exposures and exposures from commercially available particles), very few studies on human exposure during sleep exist. As the study of exposure to all possible nanomaterials during sleep is extensive, this study focuses on exposure to specifically silver nanoparticles which are present in beddings and mattresses. The reasoning behind the use of silver nanoparticles in bedding and related materials, possible routes of entry to various population groups in several sleep positions, exposure characterisation and toxicity potential of such silver nanoparticles are reviewed in this study. The toxicity potential of silver nanoparticles in vivo tests with relation to mammals and in vitro tests on human cells has been tabulated to understand the risks associated during oral, dermal and inhalation exposure to silver nanoparticles. The exposure to humans with regard to dermal absorption and oral intake has been summarised. Although potential inhalation exposure to silver nanoparticles is increasing, only a few studies address the possible toxic effect of inhaled silver particles. Determination of exposure to silver nanoparticles in beddings is a topic that has been less researched, and this review aims to provide background information for future research and help establish a comprehensive risk assessment during sleep in the times of increasing usage of nanoparticles in our daily activities. Despite the current limitations of our understanding, risk assessments must utilise the available data and apply extrapolation procedures in the face of uncertainty, in order to address the needs of regulatory programs. This would enable safe use of the antimicrobial properties of silver nanoparticles without negatively impacting human health. Until then, it would be better to adopt a conservative approach on the usage of silver nanoparticles in daily used commercial items.

Dental Caries and Developmental Defects of Enamel in the Primary Dentition of Preterm Infants: Case-Control Observational Study

AIM

Assessment of dental health in the primary dentition of preterm infants (PTI) including investigation of mother- and infant-related risk factors in a case-control study design.

MATERIAL AND METHODS

One hundred twenty-eight infants aged 3-4 years were included. Sixty-four PTI (27 males) were randomly selected from the preterm registry of the Jena University Hospital. As a control group served 64 full-term infants (FTI) recruited from the Department of Paediatric Dentistry, matched for age and sex. Dental examinations were provided by one dentist under standard clinical conditions. Caries was scored using the International Caries Detection and Assessment System (ICDAS II) and the DMFT, gingival health using the Periodontal Screening Index, and developmental defects of enamel using the DDE index. Mother- and infant-related factors were collected via a questionnaire and from medical records.

RESULTS

The caries prevalence was 50.0% (ICDAS II >0) in PTI and 12.5% (ICDAS II >0) in FTI. The caries experience was higher in PTI (DMFT 1.0 ± 3.1) than in FTI (DMFT 0.3 ± 1.0). PTI had a higher risk of caries (OR 7.0), initial lesions (OR 6.2), DDE (OR 7.5), and gingivitis (OR 6.5) than FTI. The highest risk occurred in PTI with an extremely low birth weight (<1,000 g). A higher risk of DDE was present when mothers suffered from illness during pregnancy (OR 3.9). A higher risk of caries was revealed in infants with respiratory syndrome (OR 6.2) or when their mothers had a lower socioeconomic status (OR 6.3).

CONCLUSIONS

PTI had less healthy teeth than FTI and are at a higher risk for DDE, caries, and gingivitis. The poorer dental health in PTI is associated with a low birth weight, a low socioeconomic status, and mothers' illness during pregnancy.

Impact of periodontal treatment on hospitalization for adverse respiratory events in asthmatic adults: A propensity-matched cohort study

BACKGROUND

Periodontal disease is prevalent in asthmatics, but it is unclear whether periodontal treatment plays a role in adverse respiratory events in these patients. We evaluated risk of hospitalization for adverse respiratory events (acute exacerbation, pneumonia, and acute respiratory failure) and mortality in asthmatic adults with and without periodontal treatment.

METHODS

We used National Health Insurance (NHI) claims data of Taiwan to identify 4771 asthmatic adults with periodontal disease who underwent periodontal treatment during 2000-2006. The control group consisted of asthmatic adults without periodontal disease at a 1:1 ratio matched by the propensity score. Both groups were followed up for 5years to estimate the risk of hospitalization for adverse respiratory events and mortality.

RESULTS

Compared with controls, the periodontal treatment group had lower overall incidence of hospitalization for adverse respiratory events [5.41 vs. 6.07 per 100 person-years, 95% confidence interval (CI)=0.78-0.92] and intensive care unit admissions (1.14 vs. 1.25 per 100 person-years, 95% CI=0.79-0.99). In addition, the all-cause mortality rate was significantly lower in the periodontal treatment group than in the control group during the follow-up period (1.86 vs. 2.79 per 100 person-years, 95% CI=0.59-0.71).

CONCLUSION

Asthmatic adults who underwent periodontal treatment were at lower risk of hospitalization for adverse respiratory events and mortality than those without periodontal disease. Asthmatic adults should adopt more precautionary oral hygiene and ensure that they undergo regular periodontal health checkups.

Allergic rhinitis, rather than asthma, is a risk factor for dental caries

OBJECTIVES

The association between AS (asthma) and dental caries is controversial, while that between allergic rhinitis (AR) and caries has not been established. This study aimed to verify the relationship among AR, AS and dental caries.

DESIGN

Retrospective cohort study.

SETTING

Data from Health Insurance Database of the Taiwan's National Health Insurance Research Database.

PARTICIPANTS

Nine thousand and thirty-eight children born in 2004 were obtained. Their claims data were evaluated from birth to the age of 9 years.

MAIN OUTCOME MEASURES

The frequencies of clinical visits for dental caries were calculated for primary teeth (age 1-5) and for dental transitional period (age 6-9). Differences in the frequencies of clinical visits for caries in AR vs non-AR and AS vs non-AS children were compared. Correlation between AR, AS and caries frequencies was studied, and the influences of AR drugs on the development of caries were evaluated.

RESULTS

After adjusting for confounding factors and AS case, the frequencies of clinical visits for caries were higher in AR (increased by 13%-25% and P<.001 at different age periods). The AR frequencies significantly correlated with caries frequencies in children with AR. Different AR drugs also correlated with caries formation. After adjusting for confounding factors and AR case, there was no relationship between AS and caries in children.

CONCLUSION

Asthma is not associated with dental caries, but AR can increase the frequency of clinical visits for caries. Medications for AR may also play a role in caries formation. Thus, AR may be a risk factor for childhood dental caries.

Risk of Periodontal Disease in Patients With Asthma: A Nationwide Population-Based Retrospective Cohort Study

BACKGROUND

Studies have reported an association between asthma and oral diseases, including periodontal diseases. The aim of this retrospective study is to investigate risk of periodontal diseases for patients with asthma.

METHODS

Using the claims data of National Health Insurance of Taiwan and patients without a history of periodontal diseases, 19,206 asthmatic patients, who were newly diagnosed from 2000 through 2010, were identified. For each case, four comparison individuals without history of asthma and periodontal disease were randomly selected from the general population and frequency matched (categorical matched) by sex, age, and year of diagnosis (n = 76,824). Both cohorts were followed to the end of 2011 to monitor occurrence of periodontal diseases. Adjusted hazard ratios (aHRs) of periodontal disease were estimated using Cox proportional hazards regression analysis.

RESULTS

Overall incidence of periodontal diseases was 1.18-fold greater in the asthma cohort than in the comparison cohort (P <0.001). Patients with at least three emergency visits annually had an aHR of 55.9 (95% confidence interval [CI] = 50.6 to 61.7) for periodontal diseases compared with those with a mean of less than one visit. Patients with at least three admissions annually also had a similar aHR (51.8) for periodontal disease. In addition, asthmatic patients on inhaled corticosteroid (ICS) therapy had greater aHRs than non-users (aHR = 1.12; 95% CI = 1.03 to 1.23).

CONCLUSIONS

In the studied population, asthmatic patients are at an elevated risk of developing periodontal diseases. The risk is much greater for those with emergency medical demands or hospital admissions and those on ICS treatment.

Linking medical and dental health record data: a partnership with the Rochester Epidemiology Project

PURPOSE

The purpose of this project was to expand the Rochester Epidemiology Project (REP) medical records linkage infrastructure to include data from oral healthcare providers. The goal of this linkage is to facilitate research studies examining the role of oral health in overall health and quality of life.

PARTICIPANTS

Eight dental practices joined the REP between 2011 and 2015. The REP study team has linked oral healthcare information with medical record information from local healthcare providers for 31 750 participants who have resided in Olmsted County, Minnesota. Overall, 17 718 (56%) participants are women, 14 318 (45%) are 40 years of age or older and 26 090 (82%) are white.

FINDINGS TO DATE

A first study using this new information was recently completed. This resource was used to determine whether the 2007 guidelines from the American Heart Association affected prescription rates of antibiotics to patients with moderate-risk cardiac conditions prior to dental procedures. The REP infrastructure was used to identify a series of patients diagnosed with moderate-risk cardiac conditions by the local healthcare providers (n=1351), and to abstract antibiotic prescriptions from dental records both pre-2007 and post-2007. Antibiotic prescriptions prior to dental procedures declined from 62% to 7% following the change in guidelines.

FUTURE PLANS

Dental data from participating practitioners will be updated on an annual basis, and new dental data will be linked to patient medical records. In addition, we will continue to invite new dental practices to participate in the REP. Finally, we will continue to use this research infrastructure to investigate associations between oral and medical health, and will present findings at conferences and in the scientific literature.

Oral Health-related quality of life in pediatric patients with cystic fibrosis

PURPOSE

To compare the oral health-related quality of life (OHRQoL) of 8- to 12-year-old children and 13- to 17-year-old adolescents diagnosed with cystic fibrosis (CF).

MATERIALS AND METHODS

Participants were recruited from a Midwest CF center. Parents provided demographic information and their assessment of the child's health. Patients completed the Child Oral Health Impact Profile (COHIP).

RESULTS

Thirty-nine child-parent pairs participated. Fifty four percent of the patients were male, 87% Caucasian, and 56% adolescent, with 66% of families reporting an annual income of over $100,000. Excellent or very good health, including oral health, was reported by 67% of the patients. Individuals taking 10 or more medications reported better OHRQoL while Caucasians reported better oral health and total scores than other races. Adolescents had poorer total COHIP, social-emotional well-being, and self-image scores.

CONCLUSION

Although most patients reported good or excellent oral health, adolescents reported a poorer OHRQoL than younger patients.

Perinatal factors associated with developmental defects of enamel in primary teeth: a case-control study

The present study was designed to evaluate associations between developmental defects of enamel (DDE) in the primary dentition and aspects related to mothers and preschoolers in the city of Diamantina, Brazil. A case-control study was carried out involving children aged three to five years. The case group was composed of 104 children with at least one dental surface affected by DDE. The control group comprised 105 children without DDE, matched for gender and age. The diagnosis of enamel defects was performed using the Developmental Defects of Enamel Index. Information was collected through interviews investigating socio-demographic aspects, gestation, birth weight, prematurity and breastfeeding. Simple and multiple regression analyses were performed, providing unadjusted and adjusted prevalence ratios (Poisson regression). DDE were more prevalent among children who had not been breastfed (PR=1.57; 95% CI: 1.1-2.2) and those whose mothers were under 24 years of age at the birth of the child (PR=1.41; 95% CI: 1.1-1.9). The prevalence of DDE in the primary dentition was higher among children who had not been breastfed and those whose mothers were under 24 years of age at the birth of the child.

The relationship between body system-based chronic conditions and dental utilization for Medicaid-enrolled children: a retrospective cohort study

Background

Dental care is the most common unmet health care need for children with chronic conditions. However, anecdotal evidence suggests that not all children with chronic conditions encounter difficulties accessing dental care. The goals of this study are to evaluate dental care use for Medicaid-enrolled children with chronic conditions and to identify the subgroups of children with chronic conditions that are the least likely to use dental care services.

Methods

This study focused on children with chronic conditions ages 3-14 enrolled in the Iowa Medicaid Program in 2005 and 2006. The independent variables were whether a child had each of the following 10 body system-based chronic conditions (no/yes): hematologic; cardiovascular; craniofacial; diabetes; endocrine; digestive; ear/nose/throat; respiratory; catastrophic neurological; or musculoskeletal. The primary outcome measure was use of any dental care in 2006. Secondary outcomes, also measured in 2006, were use of diagnostic dental care, preventive dental care, routine restorative dental care, and complex restorative dental care. We used Poisson regression models to estimate the relative risk (RR) associated with each of the five outcome measures across the 10 chronic conditions.

Results

Across the 10 chronic condition subgroups, unadjusted dental utilization rates ranged from 44.3% (children with catastrophic neurological conditions) to 60.2% (children with musculoskeletal conditions). After adjusting for model covariates, children with catastrophic neurological conditions were significantly less likely to use most types of dental care (RR: 0.48 to 0.73). When there were differences, children with endocrine or craniofacial conditions were less likely to use dental care whereas children with hematologic or digestive conditions were more likely to use dental care. Children with respiratory, musculoskeletal, or ear/nose/throat conditions were more likely to use most types of dental care compared to other children with chronic conditions but without these specific conditions (RR: 1.03 to 1.13; 1.0 to 1.08; 1.02 to 1.12; respectively). There was no difference in use across all types of dental care for children with diabetes or cardiovascular conditions compared to other children with chronic conditions who did not have these particular conditions.

Conclusions

Dental utilization is not homogeneous across chronic condition subgroups. Nearly 42% of children in our study did not use any dental care in 2006. These findings support the development of multilevel clinical interventions that target subgroups of Medicaid-enrolled children with chronic conditions that are most likely to have problems accessing dental care.
