The dental patient with asthma. An update and oral health considerations

Association between asthma and periodontitis: A case-control analysis of risk factors, related medications, and allergic responses

AIMS

This study aimed to investigate the association between asthma, related allergies and medication use, and the presence and severity of periodontitis among individuals at the University of Michigan School of Dentistry.

METHODS

Employing a case-control design, the study analyzed data from 892 patients, half with asthma and half without asthma. Data collection included demographics, asthma history, medication use, allergies, and periodontal examination outcomes, including probing pocket depth (PPD), mobility, furcation involvement, and radiographic bone loss (RBL). Logistic regression models assessed the relationship between asthma and periodontitis, adjusting for confounders.

RESULTS

Asthmatic patients exhibited significantly lower odds of periodontitis (OR = 0.10, p < .001) and were less likely to present with advanced stages (OR = 0.23, p < .001) and grades of the disease (OR = 0.31, p < .001) compared to non-asthmatic patients. The study also found a higher proportion of females in the asthmatic group (67% vs. 51.8%, p < .001). Smoking was identified as a significant factor associated with periodontitis in patients with asthma, with former smokers at more than double the odds (OR = 2.28, p = .035) and current smokers at a slightly lower yet significant odds (OR = 1.87, p = .050). Additionally, asthmatic patients on adrenergic inhalers had an increased likelihood of developing periodontitis (OR = 1.76, p = .045). Allergies to codeine and latex were associated with higher odds of periodontitis, with ORs of 3.41 and 6.09, respectively.

CONCLUSIONS

Asthma was found to be associated with lower odds of periodontitis. However, this association appears to be modified by smoking habits and the use of certain asthma medications, which are related to an increased likelihood of periodontitis among asthmatic patients.

Causal association between asthma and periodontitis: A two-sample Mendelian randomization analysis

BACKGROUND

A unified view of whether asthma and periodontitis interact and the direction of action is not found in previous studies. Therefore, in this article, we will elucidate bidirectional causality by two-sample Mendelian randomization (MR).

METHODS

We obtained summary-level data for asthma and periodontitis from the massive GWAS databases of several publicly available. Meanwhile, it will ensure no confounders like smoking using the Phenoscanner website to have a search over each SNP. The F statistic value of each SNP is calculated as more significant than 10. This MR analysis mainly used five MR methods: MR-Egger, weighted median, inverse variance weighted (IVW), simple mode, and weighted mode. As a result, we performed heterogeneity and horizontal pleiotropy tests.

RESULTS

We have found supporting evidence to verify the hypothesis that asthma may be a protective factor for periodontitis (IVW OR = 0.34; 95% CI = [0.132,0.87]; p = 0.025). The consistent impact direction is shown when additional asthma GWAS dataset are used (MR-Egger OR = 0.118; 95%CI = [0.016,0.883]; p = 0.04). There is no evidence of a causal effect of periodontitis at the risk of asthma in the reverse analysis (p > 0.05).

CONCLUSIONS

Our analysis found that people with asthma may have a lower risk of periodontitis than those without. This MR analysis could have significant implications for the clinical process and future research.

A comparative evaluation of the effects of respiratory diseases on dental caries

PURPOSE

The aim of this study is to evaluate the susceptibility of patients suffering from asthma and chronic obstructive pulmonary disease (COPD) to dental caries by analyzing the physical, chemical, and microbiological characteristics of saliva, which are influenced by the medications they use.

METHODS

A cohort of 104 individuals, spanning from 18 to 70 years of age, underwent a meticulous categorization based on their unique medical profiles and prescribed medication routines. Subsequently, a comprehensive evaluation was conducted to elucidate potential risk factors associated with dental caries. Alongside the assessment of decayed, missing, and filled teeth (DMFT index), decayed, missing, and filled surfaces (DMFS index), and Green and Vermillion Oral Hygiene Index-Simplified (G&V OHI-S) values, measurements were performed to gauge salivary flow rate, buffering capacity, and the presence of S. mutans, L. casei, S. aureus, and C. albicans. The acquired data were then inputted into the Cariogram software, enabling the derivation of personalized caries risk profiles for each individual.

RESULTS

The diseased group exhibited significantly elevated levels of DMFT, DMFS, and G&V OHI-S values in comparison to the control group (p < 0.01). Moreover, the caries risk levels derived from the Cariogram were found to be significantly higher in patients diagnosed with asthma and COPD (p < 0.01). Notably, no substantial distinction was observed between these two experimental groups. Furthermore, it was discerned that COPD patients utilizing two or three distinct medications did not display any discernible variation in terms of their susceptibility to dental caries (p > 0.05).

CONCLUSION

Asthma and COPD patients exhibit an increased susceptibility to dental caries as a result of their medication regimens. Hence, it is highly advisable for these individuals to demonstrate heightened vigilance in terms of oral hygiene practices and seek regular dental check-ups for continuous monitoring and preventive care.

Drugs Prescribed for Asthma and Their Adverse Effects on Dental Health

Asthma is a chronic, heterogeneous respiratory pathology characterized by reversible airway inflammation. Therapeutics focus on symptom reduction and control, aimed at preserving normal pulmonary function and inducing bronchodilatation. The objective of this review is to describe the adverse effects produced by anti-asthmatic drugs on dental health, according to the reported scientific evidence. A bibliographic review was carried out on databases, such as Web of science, Scopus, and ScienceDirect. Most anti-asthmatic medications are administered using inhalers or nebulizers, making it impossible to avoid contact of the drug with hard dental tissues and oral mucosa, and thus promoting a greater risk of oral alterations, mainly due to decreases in the salivary flow and pH. Such changes can cause diseases, such as dental caries, dental erosion, tooth loss, periodontal disease, bone resorption, as well as fungal infections, such as oral candidiasis.

Evaluation of orofacial dysfunctions and oral health-related quality of life in children with asthma

Objective: This study aimed to investigate the impact of asthma on oro-facial muscle dysfunction (OFD) and oral health-related quality of life (OHRQoL) in children. Materials and Method: A total of 158 children, 79 diagnosed with asthma and 79 healthy, were included in the study. Children diagnosed with asthma were divided into controlled and uncontrolled asthma groups. The OFD and OHRQoL of all participants were evaluated with Nordic Orofacial Test and Screening (NOT-S) and Child Perception Questionnaire (CPQ8-10). The differences and correlations between the groups were statistically evaluated (Mann-Whitney and Spearman and Chi-Square test). Results: NOT-S interview, examination, and total scores were statistically higher in the asthma group compared to healthy children and between uncontrolled and controlled asthma groups (p&lt;0.001). Higher scores were obtained in all areas of CPQ8-10 in the asthma group (p&lt;0.001). NOT-S and CPQ8-10 scores elevated compatibly in the groups diagnosed with asthma. Conclusion: OFD in asthmatic children predicts worse OHRQoL.

Dental Management of Pediatric Patients with Bronchial Asthma

Asthma is a disease marked by recurrent dyspnea caused by spasmodic bronchoconstriction. Bronchial asthma is a serious global problem that has steadily increased in prevalence during the past two decades. Oral manifestations of pediatric patients suffering from bronchial asthma are an increased upper anterior and total anterior facial height, higher palatal vaults, greater overjets, and a higher prevalence of posterior crossbites. Dental treatment of such patients requires the role of a pedodontist. Behavior management techniques, conscious sedation techniques along with medical management, and comprehensive dental treatment by a pediatric dentist may prove beneficial to such patients.

Relation between Childhood Asthma and Dental Erosion in Al-Kharj Region of Saudi Arabia: A Cross-Sectional Study

Background:

Asthma is a long-lasting disease that affects large number of the society and could impact on the oral health leading to increase in the needs of prevention and treatment. Currently, the prevalence of childhood asthma in Saudi Arabia is ranging from 9% to 33%.

Objective:

the objective was to evaluate dental erosion in control children and those with asthma.

Materials and Methods:

This was a cross-sectional study, with a sample of 100 children aged 3–12 years. Equally distribution of subjects was between the asthmatic and non-asthmatic group, at Prince Sattam Bin Abdulaziz University Dental Clinics, Alkharj, Saudi Arabia. The assessment consisted of an oral examination assessing erosive wear according to the American Academy of Pediatrics 2018 guidelines and a questionnaire to the parents/guardians addressing the background details and information about the child asthma.

Results:

Among 12 (24%) asthmatic children and 9 (18%) non-asthmatic children had dental erosion. In the adjusted analysis, no association was found between asthma and erosion. It has been shown that oral hygiene may have an effect occurrence or severity of erosion; brushing teeth once or more per day appeared to have less incidence of dental erosion compared with those not brushing their teeth regularly.

Conclusions:

This article provided no additional data than that given earlier, where no correlation was observed between asthma and dental erosion in children aged from 3 to 12 years.

The dental management of the asthmatic patients

Asthma is the most common chronic respiratory condition characterized by airway inflammation and obstruction. Our increased knowledge and understanding of the etiology and pathogenesis of this condition has widely assisted us in delivering effective therapies. Physicians strive to provide the best treatment modality to achieve symptom-control and minimize the adverse effects of medication use. Nonetheless, patients continue to endure oral complications from the use of asthma medications. As dentists, it is prudent to address these oral complications and promote the oral health of these patients by way of early preventive and therapeutic dental intervention. This must be accomplished by adhering to certain precautionary measures for the sake of avoiding intraoperative problems while optimizing oral care. In this article, we discuss the diagnosis, oral findings, dental care, and emergency management of the asthmatic patients.

Impact of asthma and its medication on salivary characteristics and oral health in adolescents: A cross-sectional comparative study

OBJECTIVE

To assess and compare the salivary characteristics and oral health and to evaluate the impact of asthma and its medication on dental caries among adolescents with and without asthma.

METHODS

A cross-sectional comparative study was conducted among 50 asthmatic and 50 nonasthmatic adolescents aged 12-15 years in Bangalore City. Data were acquired using a structured questionnaire. Salivary samples were collected to determine the flow rate, pH, buffering capacity, and Streptococcus mutans and Lactobacilli counts. Oral health assessment was performed using WHO 2013 proforma. Inferential statistics such as chi-square, student's t-test, spearman's correlation, multinomial logistic. and stepwise linear regression were applied with P < .05 considered as significant.

RESULTS

Asthmatic participants had significantly higher mean number of teeth with dental caries, gingival bleeding, and dental erosion than nonasthmatics (P < .05). The prevalence of fluorosis, traumatic dental injuries, and oral mucosal lesions in asthmatics were 34.0%, 38.0%, and 28.0%, respectively. Most of the asthmatic participants required preventive or routine (18.0%) and prompt treatment (30.0%). Statistically significant difference was found in the flow rate, pH, buffering capacity, S. mutans and Lactobacilli counts, and Decayed, Missing, Filled Teeth (DMFT) index between asthmatic and nonasthmatic participants. Severity of asthma, medication use, and dental caries experience significantly correlated with low salivary flow rate, pH and buffering capacity, and higher levels of S. mutans and Lactobacilli (P < .001). Asthmatic participants had significantly higher odds of having very low unstimulated salivary flow rate (odds ratio [OR] = 3.2), buffering capacity (OR = 2.94), highly acidic pH (OR = 3.65), high risk of S. mutans (OR = 6.02), and DMFT ≥ 1 (OR = 2.06) than nonasthmatics (P < .05).

CONCLUSION

Salivary characteristics and oral health were significantly poor in asthmatic adolescents. Asthma and its medications had significant impact on salivary characteristics and dental caries among asthmatic adolescents.

Asthma, chronic obstructive pulmonary disease, tooth loss, and edentulism among adults in the United States: 2016 Behavioral Risk Factor Surveillance System survey

BACKGROUND

Adults with chronic respiratory conditions, specifically asthma or chronic obstructive pulmonary disease (COPD), may be at risk of experiencing poor oral health due to systemic inflammation, challenges in routine oral health care, and adverse effects of medications used to treat these conditions. The authors examined the association of asthma, COPD, and coexisting asthma and COPD (asthma-COPD overlap syndrome [ACOS]) with tooth loss among US adults.

METHODS

The authors conducted a cross-sectional study using 2016 Behavioral Risk Factor Surveillance System data (N = 387,217). The authors categorized the participants with missing permanent teeth into 4 groups: asthma only (n = 38,817), COPD only (n = 19,819), ACOS (n = 13,494), no asthma, no COPD (n = 315,087). The authors used adjusted multinomial logistic regressions to examine the associations between asthma and COPD categories and tooth loss.

RESULTS

According to the authors, 5.3% of study participants reported they were edentulous; 10.7% reported 6 or fewer missing teeth. Participants with asthma only, COPD only, and ACOS had higher odds of reporting tooth loss (6 or more teeth) than those in the no asthma, no COPD group; adjusted odds ratios were 1.12 (95% confidence interval, 1.00 to 1.26) to 2.04 (95% confidence interval, 1.85 to 2.26). A lower percentage of participants with COPD and ACOS visited dentists in the past year than those with no asthma and no COPD. Interactive associations suggested participants with asthma or COPD with dental visits were less likely to report edentulism than those with neither asthma nor COPD and no dental visits.

CONCLUSIONS

Participants with asthma or COPD had higher odds of tooth loss compared with those with neither asthma nor COPD.

PRACTICAL IMPLICATIONS

People with asthma or COPD should maintain routine dental visits to reduce the risk of experiencing tooth loss.

Dental treatment in children with asthma - a review

Correlation of mast cells in different stages of human periodontal diseases: Pilot study

AIMS AND OBJECTIVES

The aim of this study was to evaluate and correlate the relationship between mast cells counts and different stages of human periodontal diseases.

MATERIALS AND METHODS

The study sample comprised 50 patients, which were divided into three groups, consisting of 10 cases of clinically healthy gingival tissues (control group) 20 cases of dental plaque-induced gingivitis with no attachment loss and 20 cases of localized chronic periodontitis (LCP) characterized by the loss of periodontal support. The samples for control group were obtained during tooth extractions for orthodontic reasons. The specimens were immediately fixed in 10% neutral buffered formalin.

CONCLUSION

In this study, LCP cases had higher mast cell counts compared to gingivitis sites or healthy tissues. Increased mast cell counts in the progressing sites of periodontal diseases may indicate the importance of these cells in the progression of chronic periodontitis.

Cariogenic Potential of Inhaled Antiasthmatic Drugs

Introduction:

The organism of children with asthma is exposed to the effects of the disease but also the drugs for its treatment. Antiasthmatic drugs have different modes that promote the caries formation which varies according to their basic pharmacological composition. Namely, these drugs have a relatively low pH (5.5), can contain sweeteners such as lactose monohydrate in order to improve the drug taste or both. Frequent consumption of these inhalers in combination with reduced secretion of saliva increases the risk of caries.

Material and methods:

The study sample consisted of 200 patients, age from 7-14 years, divided into two groups: control group (n1 = 100) consisted of healthy children and the experimental group consisted of children suffering from asthma (n2 = 100). In both groups of respondents are determined the DMFT index, plaque index value and hygienic-dietary habits using the questionnaire. The subjects in the control group had significantly higher DMFT index than subjects in the experimental group (p = 0.004). It is determined that there are no significant differences in the values of plaque index (p>0.05).

Conclusion:

The effect of different diseases or medications from their treatment, diet and fermentable carbohydrates in the etiology of dental caries cannot be observed outside the living conditions of subjects, their social epidemiologic status, age, habits, oral hygiene, fluoride use, etc.

Assessment of sleep bruxism, orthodontic treatment need, orofacial dysfunctions and salivary biomarkers in asthmatic children

OBJECTIVE

To evaluate the sleep bruxism, malocclusions, orofacial dysfunctions and salivary levels of cortisol and alpha-amylase in asthmatic children.

DESIGN

108 7-9-yr-old children were selected from Policlinic Santa Teresinha Doutor Antonio Haddad Dib (asthmatics, n=53) and from public schools (controls, n=55), Piracicaba, SP, Brazil. Sleep bruxism diagnosis was confirmed by parental report of grinding sounds and the presence of shiny and polish facets on incisors and/or first permanent molars. The index of orthodontic treatment need was used for occlusion evaluation. Orofacial dysfunctions were evaluated using the nordic orofacial test-screening (NOT-S). Salivary cortisol and alpha-amylase were expressed as "awakening response" (AR), calculated as the difference between levels immediately after awakening and 30 min after waking, and "diurnal decline" (DD), calculated as the difference between levels at 30 min after waking and at bedtime. Data were analyzed using Shapiro-Wilk/Kolmogorov-Smirnov, Chi-square, unpaired t test/Mann-Whitney and paired t/Wilcoxon tests.

RESULTS

Sleep bruxism was more prevalent in children with asthma than controls (47.2% vs. 27.3%, p<0.05). Asthmatics had higher scores of NOT-S total and interview (p<0.05). Dysfunctions on sensory function and chewing and swallowing were more frequent in asthmatics (p<0.05). Salivary cortisol AR on weekend was significantly higher for asthmatics (p<0.05). Salivary cortisol DD was significantly higher on weekday than weekend for controls (p<0.05). There were no significant differences in alpha-amylase values in and between groups.

CONCLUSIONS

The presence of asthma in children was associated with sleep bruxism, negative perception of sensory, chewing and swallowing functions, and higher concentrations of salivary cortisol on weekend.

Knowledge, attitude and practice of pediatricians and pharmacists in Riyadh City toward the use of sugar free medications

OBJECTIVE

This study was intended to assess the knowledge, attitude and practice of pediatricians and pharmacists about sugar free medications (SFMs) and their impact on oral health.

MATERIALS AND METHODS

Self-administered close ended questionnaire was handed out to all pediatricians and pharmacists in five tertiary hospitals in Riyadh (King Khalid University Hospital, King Saud Medical City, King Fahad Medical City, Prince Sultan Medical Military City, Security Forces Hospital) to investigate the knowledge, attitude and practice concerning SFMs.

RESULTS

Eighty-five pediatricians and 77 pharmacists participated in this study. The results showed that pediatricians and pharmacists have a good knowledge, but negative attitude toward SFMs. Only (5.9%) of pediatricians had formal undergraduate training which is significantly lower than pharmacists (15.6%) (p = 0.04). One-third of pediatricans and pharmacists prescribe or dispense SFMs. The most influencing factors toward prescription (pediatrician) of SFMs was the medical status of the patient (70.6%), while the most influencing factor of dispensing (pharmacists) SFMs was the availability in the pharmacy (64.9%). Two-third of pediatricians (67%) guide the parents about the risk associated with sugar-containing medications (SCMs) which is significantly higher than pharmacists (p < 0.0001). Also, 53% of pediatricians recommend oral hygiene instructions when prescribing SCMs which is also significantly higher than pharmacists (p = 0.0 02).

CONCLUSION

There is a considerable knowledge about SFMs and its impact on dental caries, among pediatricians and pharmacists participated in this study. However, their attitude toward prescribing or dispensing SFMs was not positive and may be linked to the gap in knowledge. Further training and education of healthcare providers regarding the use of SFMs and its negative impact on dental caries has to be reiterated.

Genetic variation in Ameloblastin is associated with caries in asthmatic children

AIM

Evidence suggests caries experience is higher in children with asthma. This study compared caries experience in asthmatic and non-asthmatic children and defined whether variation in the distribution of caries experience differed between the two groups and was dependent on the presence of genetic variation in enamel formation genes.

METHODS

Children with asthma were recruited at the Istanbul University, Faculty of Medicine, Department of Paediatrics, Division of Paediatric Allergy and Pulmonary Diseases, and non-affected children were recruited at the Istanbul University, Faculty of Dentistry, Department of Paedodontics. Cases (N = 100) were defined as children between the ages of 6 and 12 years with asthma and controls (N = 100) as children without asthma. Cases and controls were matched by sex and age. All study subjects received a complete dental exam, provided demographic and other caries and asthma risk factors data, and a saliva sample for DNA extraction. Caries experience was defined based on DMFT/dmft and DMFS/dmfs scores. Genotypes of 11 SNPs were selected in intronic regions of enamel development genes. PCR with TaqMan chemistry was used for genotyping all selected markers. Association between caries experience (caries-free versus caries affected) depending on asthma status and SNPs was tested with PLINK by logistic regression, adjusting by risk, and other preventive measures. p values below 0.0045 (0.05/11) were considered statistically significant.

RESULTS

Logistic regression analysis showed an association between AMBN rs4694075 and caries experience (p = 2.525e-007).

CONCLUSIONS

This study provides, for the first time, evidence that ameloblastin is associated with caries in asthmatic children.

Relation of caries status on the salivary total antioxidant levels in asthmatic children

Aim:

To study the correlation between the caries status and the salivary antioxidant levels among asthmatic children.

Settings and Design:

One hundred children within the age group of 6 12 years were selected and equally subdivided into children having a history of asthma and their healthy siblings.

Materials and Methods:

Salivary antioxidant levels were assessed using spectrophotometric method, and the caries status was recorded using DMFT (Decayed, missing and Filled Teeth Index) and dft (decayed, filled teeth index) index.

Result:

The salivary antioxidant levels were reduced among the asthmatic children which was statistically highly significant, whereas the caries prevalence was reduced, but not statistically significant.

Dental care utilization among dentate adults with asthma: findings from the 2008 Behavioral Risk Factor Surveillance System

OBJECTIVES

This study investigated dental care service utilization among dentate adults with asthma and identified factors affecting dental care use among this population.

METHODS

Data from 414,509 adults in the United States who participated in the 2008 Behavioral and Risk Factor Surveillance System were used to estimate the percentage of dentate adults with asthma who had at least one dental visit within the past year.

RESULTS

The proportion of respondents with asthma who had at least one dental visit within the past year compared with the general population was significantly lower (67.4 percent versus 71.2 percent, P < 0.001 for dental visit for any reason; 64.3 percent versus 69.6 percent, P < 0.001 for dental cleaning). The adjusted odds of a dental visit for any reason within the past year for those with asthma were 0.86 [95% confidence interval (CI), 0.81-0.91], and for dental cleaning 0.82 (95% CI, 0.78-0.87) times that of those without asthma, respectively. Multivariable modeling showed dentate adults with asthma who are male, high school or less educated, unemployed, lower income, current smokers, and have lost more than six teeth were less likely to have a dental visit within the past year.

CONCLUSIONS

Compared with nonasthmatic individuals, dentate adults with asthma had a lower frequency of dental visits in the past year. Given a higher risk of oral disease among this population, healthcare providers should focus more effort on educating certain subgroups of patients with asthma on the importance of regular dental care.

The Prevalence and Severity of Dental Caries and Oral Hygiene Status of Asthmatic Children between the Age Group of 6 and 12 Years: A Cross-Sectional Study

Aim

To assess the prevalence and severity of dental caries and oral hygiene status of 6 to 12 years old children with bronchial asthma.

Materials and methods

The study population consisted of 500 children between the age group of 6 and 12 years old, who were diagnosed with bronchial asthma and were under medication. DMFT score was assessed by WHO criteria (1997) and oral hygiene status was assessed by simplified oral hygiene index (OHI-S) by Greene and Vermillion (1964).

Results

The data was collected and analyzed using the SPSS package.15.6% of females had good oral hygiene status when compared to males who almost had 12.6 and 20.8% of children who were in the category of moderate persistent asthma had decayed teeth whereas only 4% of children in severe persistent asthma category had experienced with decayed teeth.

Conclusion

Moderate persistent group of asthmatic children who were consuming orobronchodilator form of medication are found to have high prevalence of dental caries than dry powder and metered dose inhaler.

Asthma and oral health: a review

Asthma is a chronic inflammatory condition that causes the airways to constrict and produce excess mucus, making breathing difficult. It is characterized by the obstruction of airflow which is variable over a short period of time. This condition is reversible, either spontaneously or can be controlled with the help of drugs. Asthma medication comprises bronchodilators, corticosteroids and anticholinergic drugs. Most of these drugs are inhaled using various forms of inhalers or nebulizers. The effect of these drugs on oral health is the subject of debate among dental practitioners. Patients taking asthma medication may be at risk of dental caries, dental erosion, periodontal diseases and oral candidiasis. Hence, patients with bronchial asthma on medication should receive special prophylactic attention. This article reviews the correlation between asthma and oral health, and suggests various measures to counter possible oral health problems related to asthma.

Prevalence of developmental defects of enamel in children and adolescents with asthma

OBJECTIVE

This study aimed to evaluate the prevalence of developmental defects of enamel (DDEs) in relation to asthma severity, symptom onset and pharmacological treatment in pediatric asthma patients.

METHODS

Children and adolescents (68 asthma patients and 68 controls), 5-15 years of age and residents of the city of Londrina, Brazil, were enrolled in the study. Medical and dental histories were collected through the use of a structured questionnaire. Each participant underwent a dental examination in which the examiner employed the DDE index.

RESULTS

Of the 68 asthma group subjects, 61 (89.7%) presented dental enamel defects, compared with only 26 (38.2%) of those in the control group. Using multivariate logistic regression analysis, we estimated the risk of DDEs in permanent dentition to be 11 times higher in pediatric subjects with asthma than in those without (OR = 11.88, p = 0.0001). The occurrence of dental enamel defects correlated with greater asthma severity (p = 0.0001) and earlier symptom onset (p = 0.0001). However, dental enamel defects did not correlate with the initiation of treatment (p = 0.08) or the frequency of medication use (p = 0.93).

CONCLUSIONS

Pediatric patients with severe, early-onset asthma are at increased risk of dental enamel defects and therefore require priority dental care.

The effects of xerogenic medications on oral mucosa among the Veterans Dental Study participants

OBJECTIVES

To examine the association of xerogenic medications with the oral mucosa inflammation score (OMS) in US male veterans.

METHODS

The relationship of having the worst 25th percentile in OMS and intake of xerogenic medications with different pharmacologic indications was analyzed by logistic regression, controlling for age in 3 categories (< or =44, 45-64, > or =65), smoking, disease burden index, alcohol abuse, and the duration of medication, in 290 subjects participating in the Veterans Dental Study.

RESULTS

When polypharmacy and denture-wearing status in addition to the aforementioned covariates were controlled, the odds ratios for cardiovascular disease medications and sympathetic agonists were 2.82 (95% confidence interval [CI] 1.35-5.91, P < .006), and 2.96 (CI 1.21-7.26, P < .02), respectively, and those for psychotropics and antihistamines were 2.12 (CI 0.94-4.80, P < .06) and 2.09 (CI 0.80-5.48, P < 0.14), respectively.

CONCLUSION

Xerogenic medication may be associated with oral mucosal pathology.

Dental management of patients with obstructive pulmonary diseases

Many dental patients have obstructive pulmonary disease, such as chronic bronchitis, emphysema, and bronchial asthma. These diseases have different etiologies but may have overlapping signs and symptoms. Diagnosis and treatment are becoming more sophisticated so that morbidity and mortality are improving. Most dental patients with these morbidity and mortality are improving. Most dental patients with these disease can be treated safely with only minor adjustments to procedures. Cigarette smoking is a common risk factor that dental health care providers can address with a simple program called the five A's.

Asthma medication may influence the psychological functioning of children

Asthma is a global health problem with up to 15% of children suffering from the disease. It has been shown by various researchers that symptomatic asthmatic patients have increased levels of free serotonin in plasma when compared with asymptomatic patients. Thus, some researchers suggest that reducing the concentration of free serotonin in plasma might be useful in treating patients with asthma. Low levels of serotonin, has however, been linked to various psychological conditions like depression, oppositional defiant disorder, ADHD and even conduct disorder. Research has indicated that products like methylphenidate (also known by the brand names as e.g., Ritalin, Concerta, Metadate and others) and other stimulants used for these conditions, particularly ADHD, exert their paradoxical calming effects by boosting serotonin levels in the brain. Therefore, the hypothesis suggest that some children using asthma medication that lowers serotonin levels, might present with symptoms of depression ADHD, oppositional defiant disorder and even conduct disorder. They may be using asthma medication that lowers serotonin and additionally use methylphenidate that boosts serotonin levels for e.g., ADHD. The hypothesis therefore suggests that asthmatic children presenting with psychological complaints, be treated holistically and serotonin levels measured before coming to conclusions regarding their psychological functioning.

Corticosteroids, depression and the role of serotonin

Patients frequently use medications simultaneously for different complaints, without being aware of the interactions these products may have. An example of this is the simultaneous use of corticosteroids and medications for depression, defiant or aggressive behaviour. Research has also indicated that corticosteroids lower serotonin levels. However, lowered serotonin levels may result in depression, aggression and other psychological conditions. These secondary complaints, caused by the corticosteroids and other products that lower serotonin levels, may then be treated with selective serotonin reuptake inhibitors (SSRIs) or psycho-stimulants (that are known to indirectly increase serotonin levels). The current research takes a look at lowered serotonin levels when using corticosteroids, as well as the interactions with SSRIs and psycho-stimulants. Furthermore, evidence is presented to prove the hypothesis that some individuals with asthma (e.g. children using systemic corticosteroids that lower serotonin levels) might present with symptoms of depression, attention deficit hyperactivity disorder (ADHD), oppositional defiant disorder and even conduct disorder; and that treating these secondary complaints with SSRIs and psycho-stimulants will result in the upregulating of serotonin levels, and that, in turn, will trigger asthma.
