Periodontal disease prevalence and oral hygiene status of adults with cystic fibrosis: A case-control study.

AIM: To investigate the prevalence of gingivitis and periodontitis, and the oral hygiene status of adults with cystic fibrosis (CF) in the Republic of Ireland. MATERIALS AND METHODS: A case-control study in the form of a clinical examination of 92 adults with a diagnosis of CF was carried out in the adult CF unit in Cork University Hospital. A 40-item questionnaire was used to capture socio-demographic variables and medical and dental information. Two calibrated examiners carried out a periodontal assessment on participants, using the WHO-recommended CPI-modified index, and oral hygiene status was measured using the Greene-Vermillion index. The results were compared with a population-based control group of similar socio-demographic profile. RESULTS: Oral hygiene levels (plaque and calculus) were significantly worse in people with CF, with a median plaque index of 0.83 (interquartile range [IQR] 0.333-1.542) in the CF group compared with 0.5 (IQR 0.167-0.667) in the non-CF group. Calculus index in the CF group was 0.33 (IQR 0.17-0.83) compared with 0.33 (IQR 0.125-0.33) in the non-CF group. However, periodontal disease levels were significantly lower in the CF group. Gingivitis (bleeding on probing ≥ 10% sites) was seen in 67.4% of the CF group, compared with 83.7% of the non-CF group, OR 0.365 (95% confidence interval [CI] 0.181-0.736), relative risk (RR) 0.779 (95% CI 0.655-0.928). Mild periodontitis (periodontal probing depth [PPD] < 5 mm) was seen in 15.2% of the CF group, compared with 31.5% of the non-CF group, OR 0.390 (CI 0.190-0.800), RR 0.483 (95% CI 0.273-0.852). Severe periodontitis (PPD ≥ 6 mm) was seen in 0% of the CF group, compared with 9.8% of the non-CF group. There was a tendency, albeit non-significant, towards reduced periodontitis in PWCF who regularly took antibiotics, particularly azithromycin. CONCLUSIONS: In this study, adults with CF had poor oral hygiene practices, with high levels of plaque and calculus. Despite this finding, adults with CF had lower levels of clinical gingivitis and periodontitis than seen in a non-CF control group. Further study is required to examine the causes of this phenomenon.

The prevalence of developmental defects of enamel in people with cystic fibrosis: a systematic review.

BACKGROUND: Oral health impacts systemic health, individual well-being, and quality of life. It is important to identify conditions that may exacerbate oral disease to aid public health and policy development and promote targeted patient treatment strategies. Developmental defects can increase an individual's risk of dental caries, hypersensitivity, premature tooth wear, erosion, and poor aesthetics. As part of an ongoing study assessing oral health in adults with cystic fibrosis at Cork University Dental School and Hospital, a systematic review of available literature was conducted to assess the prevalence of enamel defects in people with cystic fibrosis. AIMS: To critically evaluate the literature to determine if the prevalence of developmental defects of enamel is higher in people with cystic fibrosis (PwCF). METHODS: Data Sources: Three online databases were searched Embase, Scopus, and Web of Science Core Collection. Studies that examined an association between cystic fibrosis and developmental defects of enamel were included in this systematic review. RESULTS: The initial search identified 116 publications from the following databases Embase, Web of Science Core Collection, and Scopus. Eleven studies were included for qualitative analysis. Nine studies concluded that PwCF had a higher prevalence of enamel defects than control people and one study found no difference in cystic fibrosis (CF) status. All studies had a risk of bias that may influence study results and their interpretation. CONCLUSIONS: The results of the systematic review show a consistent pattern that PwCF have a higher prevalence of DDE than people without CF. Genetic dysfunction, chronic systemic infections, and long-term antibiotic use are possible aetiological causes. This review highlights the need for future studies to investigate if DDEs are caused by the underlying CFTR mutation or as a consequence of disease manifestations and/or management.

Current practices and attitudes of dental practitioners regarding the provision of dental treatment for patients with solid organ transplants.

BACKGROUND: Solid organ transplant provides a lifeline for people with end stage organ failure. Each year the number of individuals in receipt of a solid organ transplant is increasing. Prevention of post-transplant sepsis and infection are critical for transplant success. The oral cavity contains more than 700 different species of bacteria and is a potential reservoir for disease causing pathogens. Prior to undergoing solid organ transplant, individuals must receive a certification of dental health from a dental practitioner. There are currently no guidelines or protocols for dental practitioners to follow when certifying a patient as dentally fit. This allows for a wide variation of the term 'dentally fit'. This survey was conducted as part of a larger study assessing the oral health of adults with cystic fibrosis ongoing in Cork University Dental School and Hospital. The aim of the study was to ascertain current practices and attitudes of dental practitioners regarding the provision of dental treatment pre and post solid organ transplantation. METHODS: An anonymous cross sectional survey of dental practitioners in Ireland was conducted. RESULTS: The data collected showed a wide variation in the provision of treatment for patient undergoing or in receipt of a solid organ transplant. CONCLUSION: It demonstrates a need for further research to be conducted to ascertain the full impact solid organ transplant has on oral health, so that guidelines can be developed to aid both dental and medical professionals in the treatment of this vulnerable cohort.

Exploring facilitators and barriers associated with oral care for inpatients with dysphagia post-stroke.

OBJECTIVE: To explore the attitudes, facilitators and barriers in providing oral care for inpatients with dysphagia post-stroke as perceived by healthcare professionals. BACKGROUND: Dysphagia is a common complication of stroke and is associated with a higher incidence of aspiration pneumonia, malnutrition and dehydration. In the acute phase of stroke recovery, a dental professional is not usually part of the multidisciplinary team caring for the patient and oral care is the responsibility of the healthcare professionals in the stroke unit. There is a lack of high-quality evidence to demonstrate the most effective method of providing oral care for patients with dysphagia post-stroke. MATERIALS AND METHODS: This was a single-site study conducted with healthcare professionals working in the Stroke Unit of Cork University Hospital in Ireland, using focus groups and a qualitative thematic analysis approach. RESULTS: A total of three focus groups were conducted in the Stroke Unit with 17 healthcare professionals. The focus groups included representation from all healthcare professional groups providing direct clinical care to patients on the Stroke Unit including geriatric medicine, dietetics, speech and language therapy, healthcare assistance, nursing, occupational therapy and physiotherapy. A qualitative thematic analysis was carried out and seven overarching themes emerged from the data. Three themes related to facilitators to providing oral care for this patient group: (i) a focus on oral care in both policy and practice, (ii) expanding professional roles in the provision of oral care, (iii) perceived importance of oral care in recovery and rehabilitation. Four themes related to barriers to the provision of oral care for this patient group: (i) lack of confidence and concerns related to the perceived risk for patients with dysphagia, (ii) unique challenges of patient and stroke-related factors, (iii) lack of resources and time and (iv) perceived importance of oral care in recovery and its relative importance with competing demands. CONCLUSION: Members of the stroke multidisciplinary team believe that they all have a part to play in the delivery of oral care for patients with dysphagia post-stroke. Opportunities exist for the development of multidisciplinary interventions to improve the oral cavity assessment and oral care provided in the Stroke Unit.

"Oral Nutritional Supplements: Sugar Content and Potential Dental Implications".

OBJECTIVES: The objectives of this article are to list the most commonly prescribed Oral Nutritional Supplements in the UK and Ireland and their sugar content; and to raise awareness among the dental profession regarding their uses and potential dental risks involved. BACKGROUND: Many older patients benefit from Oral Nutritional Supplements. Prescribers may not consider dental implications of these. Patients may not think to disclose these medications to their dentist. MATERIALS AND METHODS: A list of commonly prescribed Oral Nutritional Supplements in the UK and Ireland was compiled. Nutritional information was obtained from the manufacturers' website and arranged in order of decreasing sugar content. Potential dental implications are discussed and recommendations made for dental practitioners. RESULTS: Pre-formed Oral Nutritional Supplements can contain between 6.6 and 27.2 g of sugar per serving. Powdered Oral Nutritional Supplements, which are to be mixed with 200 ml whole milk, contain between 16.4 and 35.0 g sugar per serving. The "shot"-type Oral Nutritional Supplements contain less sugar, ranging from 0.0 to 4.0 g per serving. CONCLUSIONS: The sugar content of frequently prescribed Oral Nutritional Supplements can be high. While they are beneficial in assisting the patient to maintain a healthy BMI, they may increase the risk of dental caries. Dental professionals should enquire specifically about Oral Nutritional Supplements during history taking, particularly in groups who are likely to be prescribed such supplements. Consideration should also be given to increasing caries-preventive measures for patients who take these supplements.

Failure rates of class V restorations in the management of root caries in adults - a systematic review.

OBJECTIVE: The aim of this systematic review was to compare cumulative failure rates of different restorative materials in carious class V lesions on the root surfaces of adult patients. BACKGROUND: The prevalence of root caries is set to increase in the coming years as a result of ageing of the population and a concomitant reduction in levels of edentulousness. Evidence is needed to assist practitioners to select the most appropriate restorative material for use in these lesions. METHODS: A search of the literature was undertaken using the electronic databases of PubMed, Embase, CENTRAL and OpenSIGLE using keywords relevant to the search question. Two review authors conducted the electronic search independently, and any conflict was resolved by discussion. The references quoted in the full text articles extracted were hand searched for any further eligible studies. RESULTS: Sixty non-duplicate citations were screened. Following review of the titles, abstracts, texts and application of the pre-determined inclusion/exclusion criteria, five studies remained. CONCLUSION: There is a need for more research in this area as many of the studies identified in this systematic review treated post-radiation, xerostomic patients which are not typical of the general population. Increased adherence to CONSORT guidelines for reporting is also advised to facilitate future systematic review and meta-analysis in this area.

Minimal intervention dentistry and older patients. Part 1: Risk assessment and caries prevention.

Ten million people in the UK today are aged over 65. The latest projections estimate that there will be 5 1/2 million more people aged 65 and older in the next 20 years. This projected pattern of population ageing will have profound consequences for dentistry. Minimal intervention dentistry (MID) is a modern evidence-based approach to caries management in dentate patients that uses the 'medical model' whereby disease is controlled by the 'oral physician'. This approach offers considerable benefits over conventional dentistry for older patients. It encourages patients to be responsible for their oral health through the provision of both knowledge and motivation. MID encompasses risk assessment for dental disease, early detection and control of disease processes, and minimally invasive treatment. Clinical Relevance: Risk assessment tools can aid the general dental practitioner and the patient to develop a suitable caries prevention programme for that individual and reduce the need for future operative intervention.

Minimal intervention dentistry and older patients part 2: minimally invasive operative interventions.

UNLABELLED: As described in the first paper of this two part series, the expansion of our older population and the concomitant reduction in levels of edentulism will result in an increase in the number of patients presenting in general practice with complex restorative challenges. The application of the concepts of minimal intervention dentistry and minimally invasive operative techniques may offer a powerful armamentarium to the general dentist to provide ethical and conservative treatment to older patients. CLINICAL RELEVANCE: When it is unavoidable, operative intervention should be as minimally invasive as practicable in older patients to preserve the longevity of their natural dentition.

The prevalence of developmental defects of enamel in a cohort of adults with cystic fibrosis - A cross sectional study.

OBJECTIVES: Cystic Fibrosis is an autosomal recessive condition. It is a multisystem disease treated with a broad range of pharmacological therapies, diet and nutrition, and physiotherapy. Previous studies suggest that people with cystic fibrosis have a higher prevalence of developmental defects of enamel which may place this population at a greater risk of developing oral diseases such as caries. The aim of this study was to assess a cohort of people with cystic fibrosis (PwCF) for the presence of developmental defects of enamel and compare the results with a control group of people without cystic fibrosis. METHODS: A cross sectional study involving 92 participants with cystic fibrosis and 92 controls was conducted in Cork University Dental School & Hospital. All participants completed a detailed questionnaire prior to undergoing a full clinical examination. The Developmental Defect of Enamel Index was used as a measurement index. All data was statistically analysed with the help of statisticians from Cystic Fibrosis Registry of Ireland. RESULTS: 64 % (n = 59) of PwCF had enamel defects compared to just 30 % (n = 28) of people without cystic fibrosis. The median number of teeth affected by enamel defects in the study group was 1.5, compared to 0 in the control group. CONCLUSION: In this study the cohort of PwCF had more enamel defects than people without CF. Further research is required to investigate the aetiology of these findings. CLINICAL SIGNIFICANCE: Clinicians should be vigilant after teeth have erupted in PwCF as they may have an increased susceptibility to developmental defects of enamel.

An analysis of the attitudes of dental patients attending general dental practice in Galway.

AIM: To describe the patterns of dental attendance and attitudes towards tooth loss of general dental practice patients in Galway. OBJECTIVES: 1. To determine the pattern of adult dental attendance in general practices in Galway; and, 2. To examine the oral health attitudes of these patients. METHOD: Questionnaires were distributed to 311 consecutive adult patients in the waiting rooms of ten general dental practices in Galway, which were randomly selected from the telephone directory. RESULTS: A total of 254 of the 311 questionnaires distributed were fully completed, returned and included in the results, giving a response rate of 81.7%. A total of 59% of dentate participants attended their dentist for annual or biannual examinations compared to 23% of edentate patients. Some 10.5% of medical card holders and 0.5% of non-medical card holders were edentulous. CONCLUSIONS: The data from the survey indicated that medical card holders in Galway were more likely to be edentulous than nonmedical card holders. Edentate patients were less likely to be regular dental attenders than dentate patients.

Self-reported dental attendance, oral hygiene habits, and dietary habits of adults with cystic fibrosis.

AIMS: To evaluate the dental attendance, oral hygiene habits, and dietary habits of adults with Cystic Fibrosis in the Republic of Ireland. METHODS AND RESULTS: A cross-sectional study was carried out using a structured anonymous questionnaire. A total of 71 adults with Cystic Fibrosis responded. While the majority of respondents (66.2%) saw a dentist in the preceding year, 15.5% had not attended a dentist for over 2 years. Smoking and alcohol consumption levels were low. 63.4% brushed twice or more daily, with 70.4% using a Fluoride containing toothpaste. 62% did not use any interdental cleaning aid. 5.6% changed their toothbrush at least once a month, but for 22.5% it was over 6 months. 70.4% used fluoride toothpaste. 38% snacked three or more times daily and 29.5% consumed fizzy drinks at least once daily. CONCLUSIONS: The alcohol and tobacco consumption in this study group was low. However, a large proportion frequently consumed sugar-rich foods, and they did not change their toothbrush, brush their teeth, or attend the dentist as regularly as is advised. More targeted advice may be necessary to improve the oral hygiene habits of adults with Cystic Fibrosis.

Oral care considerations for people with cystic fibrosis: a cross-sectional qualitative study.

OBJECTIVES: To investigate the attitudes of adults with Cystic Fibrosis (CF) towards dental attendance and any perceived barriers to treatment. METHODS: A cross sectional survey in the form of a structured, anonymous questionnaire was used to obtain information regarding adults with CF's feelings towards dentists and dental treatment. The final version of the questionnaire was based on a collaborative effort between researchers at Cork University Dental School and Hospital and Cystic Fibrosis (CF) patient advocates from CF Ireland. Participants were recruited via CF Ireland's mailing list and social media channels. The responses underwent descriptive statistical analysis and inductive thematic analysis. RESULTS: A total of 71 people (33 Male: 38 Female) over the age of 18 living with CF in the Republic of Ireland responded to the survey. 54.9% of respondents were unhappy with their teeth. 63.4% felt that CF had an impact on oral health. 33.8% were anxious about attending their dentist. Respondents believed that CF has impacted on their oral health due to the medications and dietary requirements involved, as well as tiredness and other side effects of CF. Reasons for being anxious about attending the dentist included cross infection concerns, issues with the dentist, with tolerating treatment, and with the teeth themselves. Respondents wanted dentists to be aware of the practicalities of dental treatment for people with CF, especially their discomfort with lying back. They also want the dentist to be aware of the impact that their medication, treatment and diet has on their oral health. CONCLUSIONS: Over one third of adults with CF reported anxiety about attending the dentist. Reasons for this included fear, embarrassment, cross infection concerns and problems with treatment, especially being in the supine position. Adults with CF want dentists to be aware of the impact that CF can have upon dental treatment and oral health care.

Toothwear and the older patient.

UNLABELLED: Toothwear is commonly observed in dentate older patients and may be physiological or pathological in nature. Toothwear can be caused by abrasion, attrition, erosion or a combination of aetiologies. Where treatment is required, a number of options exist, including the use of adhesive materials and fixed and removable prosthodontics. CLINICAL RELEVANCE: With patients retaining natural teeth into old age, physiological and pathological toothwear amongst dentate older patients is an increasingly common presentation.

Caries and the older patient.

UNLABELLED: Ageing of the population, together with prolonged retention of teeth, has brought new challenges to dentistry. Whereas in the past oral care for the elderly was restricted to provision of dentures, older patients are now presenting with dental caries and failed restorations. These problems may have an impact on their general health and quality of life. Poor oral hygiene, xerostomia and diet are among the risk factors for caries in older patients and need to be addressed in order to achieve control of the disease. Carious lesions can be treated conservatively in many cases or may need surgical management. CLINICAL RELEVANCE: Caries is an oral health issue among older patients and can result in tooth loss. Oral health has a great impact on general health and quality of life of elderly people.

Gerodontology in Context.

The impact of ageing on society, the patient and his/her oral state is summarized, with one case being outlined as an example.

Age-related oral changes.

UNLABELLED: Age-related oral changes are seen in the oral hard and soft tissues as well as in bone, the temporomandibular joints and the oral mucosa. As older patients retain their natural teeth for longer, the clinical picture consists of normal physiological age changes in combination with pathological and iatrogenic effects. CLINICAL RELEVANCE: With an ageing population retaining more of its natural teeth for longer, dental professionals should expect to observe oral age changes more frequently.

Gerodontology: Now and the Future.

In this the first article in a series, the discipline of Gerodontology is placed in context and the issues of what constitutes ageing, the demography of the older population, and changes in oral health are considered. Future clinical challenges to the profession and in the delivery of oral healthcare are also outlined.

Managing an Ageing Population: Challenging Oral Epidemiology.

Global population projections indicate that the proportion of older people is increasing and will continue to do so for the foreseeable future. Many countries are already experiencing the challenges of managing an ageing population, including increased pension contributions from workers, rises to national retirement ages, and spiralling healthcare costs. In oral health terms, in addition to simply an ageing population, epidemiological studies have demonstrated significant changes in the oral health of older adults in recent years. As the numbers of edentulous older adults has declined, there has been a significant increase in the number of partially dentate elderly. Changing attitudes, improved access to dental care and more effective preventative programmes have meant that large numbers of patients are now retaining natural teeth into old age. However, as older patients retain natural teeth for longer, the dental profession is charged with controlling chronic dental diseases in an increasingly challenging oral environment.

Periodontal and oral health status of people with Cystic Fibrosis: a systematic review.

INTRODUCTION AND OBJECTIVES: People with Cystic Fibrosis (PWCF) may be presumed to be at lower risk of periodontal disease due to long term antibiotic use but this has not been comprehensively investigated. The oral hygiene and periodontal status of PWCF in comparison to the general population is not well established. The objective of this systematic review was to critically evaluate the literature on periodontal and oral hygiene status in PWCF to see if this group are at increased risk of periodontal disease (gingivitis or periodontitis). DATA SOURCES: 5 databases were searched: Scopus, MEDLINE, Embase, Cochrane Library and Web of Science. STUDY SELECTION: The search resulted in 614 publications from databases with one more publication identified by searching bibliographies. 13 studies were included in the qualitative analysis. CONCLUSIONS: The majority of studies showed better oral hygiene, with lower levels of gingivitis and plaque among people with Cystic Fibrosis (PWCF) than controls. Interestingly, despite this, many studies showed that PWCF had higher levels of dental calculus. Three studies found there was no difference in Oral Hygiene between PWCF and controls. One study found that PWCF aged between 6 and 9.5 years had increased levels of clinical gingivitis, and one study showed that PWCF with gingivitis had more bleeding on probing than people without CF. The vast majority of PWCF examined were children- only five studies included people over 18 years, and only one looked exclusively at adults. There is a need for further study into the periodontal health of PWCF- particularly those over the age of 18. CLINICAL SIGNIFICANCE: There are currently no guidelines referring to oral care in PWCF. Studies have suggested that the oral cavity acts as a reservoir of bacteria which may colonise the lungs. If PWCF are at increased risk of periodontal disease, they should attend for regular screenings to facilitate early detection.

Bonding auto-polymerising acrylic resin to acrylic denture teeth.

This study investigated the effect of surface treatments on the shear bond strength of an auto-polymerising acrylic resin cured to acrylic denture teeth. The surface treatments included a combination of grit-blasting and/or wetting the surface with monomer. Samples were prepared and then stored in water prior to shear testing. The results indicated that the application of monomer to the surface prior to bonding did not influence the bond strength. Grit blasting was found to significantly increase the bond strength.
