Oral Health in Young Australian Aboriginal Children: Qualitative Research on Parents' Perspectives.

Despite dedicated government funding, Aboriginal Australians, including children, experience more dental disease than other Australians, despite it being seen as mostly preventable. The ongoing legacy of colonization and discrimination against Aboriginal Australians persists, even in health services. Current neoliberal discourse often holds individuals responsible for the state of their health, rather than the structural factors beyond individual control. While presenting a balanced view of Aboriginal health is important and attests to Indigenous peoples' resilience when faced with persistent adversity, calling to account those structural factors affecting the ability of Aboriginal people to make favorable oral health choices is also important. A decolonizing approach informed by Indigenous methodologies and whiteness studies guides this article to explore the perceptions and experiences of Aboriginal parents ( N = 52) of young children, mainly mothers, in Perth, Western Australia, as they relate to the oral health. Two researchers, 1 Aboriginal and 1 non-Aboriginal, conducted 9 focus group discussions with 51 Aboriginal participants, as well as 1 interview with the remaining individual, and independently analyzed responses to identify themes underpinning barriers and enablers to oral health. These were compared, discussed, and revised under key themes and interpreted for meanings attributed to participants' perspectives. Findings indicated that oral health is important yet often compromised by structural factors, including policy and organizational practices that adversely preclude participants from making optimal oral health choices: limited education about prevention, prohibitive cost of services, intensive marketing of sugary products, and discrimination from health providers resulting in reluctance to attend services. Current government intentions center on Aboriginal-non-Aboriginal partnerships, access to flexible services, and health care that is free of racism and proactively seeks and welcomes Aboriginal people. The challenge is whether these good intentions are matched by policies and practices that translate into sustained improvements to oral health for Aboriginal Australians. Knowledge Transfer Statement: Slow progress in reducing persistent oral health disparities between Aboriginal and non-Aboriginal Australians calls for a new approach to this seemingly intractable problem. Findings from our qualitative research identified that structural factors-such as cost of services, little or no education on preventing oral disease, and discrimination by health providers-compromised Aboriginal people's optimum oral health choices and access to services. The results from this study can be used to recommend changes to policies and practices that promote rather than undermine Aboriginal health and well-being and involve Aboriginal people in decisions about their health care.

Oral health interventions in Australian Aboriginal communities: a review of the literature.

Aboriginal Australians experience significant disparities in oral health with even poorer outcomes reported in rural and remote areas. The high rates of preventable dental disease in Aboriginal communities are a serious concern from a social standpoint and in terms of service provision and health care expenditure. In this review, primary research literature was comprehensively reviewed. Papers were selected if they reported designing or implementing an intervention or oral health programme specific to the needs of Aboriginal communities. Twenty-one publications fulfilled the inclusion criteria with 19 different interventions being described. Interventions were categorized using a classification adapted from the work of Whitehead (2002). The review identified interventions that aimed to reduce early childhood caries, increase services to remote communities, develop the role of Aboriginal health workers, improve oral health literacy, establish water fluoridation and provide periodontal therapy. Implementing successful oral health interventions in Aboriginal communities is a challenge that is compounded by the complex interplay between psychosocial and cultural determinants. Even interventions that follow a rigorous and consultative design have a high failure rate in Aboriginal communities if upstream determinants of health are not adequately understood and addressed.

Compliance of post-radiation therapy head and neck cancer patients with caries preventive protocols.

BACKGROUND: Caries prevention is paramount in safeguarding the life quality of head and neck cancer patients and is dependent on patient compliance with caries preventive protocols. The purpose of this study was to examine this compliance. METHODS: All records of patients referred to one public oral medicine clinic servicing a head and neck oncology unit of one major Western Australian hospital, between January 2005 and December 2011, were examined. Data extracted included patient and cancer characteristics and compliance with dietary advice, dental care, oral hygiene instruction and fluoride use over a follow-up period of at least 12 months. Compliance was assessed against various oral health outcomes and patient characteristics. RESULTS: Of the 116 participants, 75.9% complied with all caries preventive measures over a mean follow-up period of 45 months. Non-compliance with regular dental attendance (P = 0.004), oral hygiene instruction (P = 0.009), dietary advice (P = 0.034) and daily fluoride use (P = 0.018) were associated with the development of dental caries post-treatment. The presence of dental caries at the time of cancer diagnosis was predictive of poorer compliance. CONCLUSIONS: High compliance with caries preventive measures is attainable in the head and neck cancer patient group. Factors other than fluoride use seem important in caries prevention.

Geriatric dentistry, teaching and future directions.

BACKGROUND: Many nations are facing a demographic shift in the age profile of their population, leading the World Health Organization to a 'Call for Public Health Action' on the oral health of older people. METHODS: A search of the literature relevant to geriatric dentistry teaching was undertaken using MEDLINE, Web of Science, Eric and Psychlit. A search of dental professional school websites in Australia and policy and international practice documents was undertaken. RESULTS: The international literature describes requirements for geriatric dentistry courses and various approaches to teaching, including didactic teaching, practical experiences and external placements. Challenges are identified in the area of geriatric dental education. Educational institutions (with others) have an obligation to lead change, yet there appears to be little formal recognition in Australian dental curricula of the need to develop quality education and research programmes in geriatric dentistry. CONCLUSIONS: Internationally, the inclusion of geriatrics within dental curricula has been the subject of consideration since the 1970s. The current evidence indicates that geriatrics/gerodontology is not a significant component of dental curricula. Given the projected age distribution in many countries, the need for implementation of dental curriculum content in the area of geriatrics/gerodontology is evident.

Oral health care in remote Kimberley Aboriginal communities: the characteristics and perceptions of dental volunteers.

BACKGROUND: Aboriginal Australians face significant disparities in oral health and this is particularly the case in remote communities where access to dental services can be difficult. Using volunteers to provide dental care in the remote Kimberley region of Western Australia is a novel approach. METHODS: This study comprised an anonymous online survey of volunteers working with the Kimberley Dental Team (KDT). The survey had a response fraction of 66% and explored volunteer demographic characteristics, factors that motivated their involvement, perceptions of oral health among Aboriginal communities, and barriers and enablers to oral health in remote Aboriginal communities. RESULTS: Volunteers were more likely to be female, middle-aged and engaged in full-time employment. The two most common reasons reported for volunteering were to assist the community and visit the Kimberley region. Education and access to reliable, culturally appropriate care were perceived as enablers to good oral health for Aboriginal people in the Kimberley while limited access to services, poor nutrition and lack of government support were cited as barriers. CONCLUSIONS: Volunteers providing dental services to remote areas in Western Australia had a diverse demographic profile. However, they share similar motivating factors and views on the current barriers and enablers to good oral health in remote Aboriginal communities.

Oral cavity squamous cell carcinoma - characteristics and survival in aboriginal and non-aboriginal Western australians.

BACKGROUND: Squamous cell carcinoma (SCC) is the most common type of malignancy affecting the oral cavity. While exposures to main risk factors for oral SCC such as smoking and alcohol use are higher amongst the Aboriginal people, little is known about oral cancer in this population. This study aimed to describe characteristics and survival of oral SCC in Aboriginal and non-Aboriginal Western Australians. METHODS: All primary oral SCC cases reported to the Western Australian Cancer Registry (WACR) between 1990 and 1999 were analysed with respect to person characteristics including: date of birth, sex and indigenous status; and disease characteristics including: date of biopsy, disease stage and site as well as date of recurrence and date of death. Exclusion criteria included diagnosis not based on incisional or excisional biopsy, diagnosis other than oral SCC or a history of another malignant neoplasm. RESULTS: Aboriginal individuals were more likely to reside in rural areas. No statistically significant differences in oral SCC characteristics and survival were noted between Aboriginal and non-Aboriginal Western Australians. CONCLUSION: This study provides new information on person and disease characteristics of Aboriginal Western Australians diagnosed with oral SCC.

International approaches to Indigenous dental care: what can we learn?

Indigenous populations around the world have significantly poorer oral health and inequalities in access to dental care largely attribute to the social determinants of health. Reviewing international literature offers an opportunity to better understand appropriate approaches for policy and practice in Australia. This article is a descriptive narrative review based on primary research literature discussing informative international approaches to Indigenous dental care. Approaches identified in the literature included integration of dentistry with primary health care and traditional practice, training and use of oral health professionals and approaches used at different stages of life, particularly in the management of early childhood caries. The international literature provides a range of approaches to Indigenous oral health. Tailored, culturally appropriate family and community based initiatives that address the multidisciplinary issues confronting Indigenous communities were most highly regarded.

Internet information on child oral health and the first dental visit.

BACKGROUND: This study evaluated the available online information regarding a child's first dental visit (CFDV) and compares this with internationally recognized guidelines for the timing of CFDV. METHODS: Online information regarding CFDV was searched using the Google search engine under the Australian domain for four selected search terms and limited to the first 50 results. The websites of selected professional dental associations were also investigated for recommended CFDV timing. Guidelines recommended the CFDV from when the first tooth erupts or by the age of one year. RESULTS: Information on timing for CFDV was available on the internet and consistent with recognized guidelines for almost half of the 157 sites examined. Information on CFDV was consistent with guidelines when mentioned in professional dental association and public (government and corporate) sites. Misinformation regarding CFDV was primarily associated with dental forums and sites owned by dental professionals. The three most popular topics of additional information included oral hygiene instruction, procedures for age-one CFDV and preparing the child for the CFDV. CONCLUSIONS: Internet information regarding a child's first dental visit was generally informative but not always in agreement with the recommendations of professional dental associations. Misinformation regarding CFDV was primarily associated with dental forums and dental professional owned sites.

Total population investigation of dental hospitalizations in indigenous children under five years in Western Australia using linked data.

BACKGROUND: The aim of this study was to compare dental hospital admissions in a total state birth population of Indigenous and non-Indigenous children aged under five years in Western Australia. METHODS: Midwives' notification data were linked to databases of deaths, admissions, birth defects and intellectual disability. Births during 1980-1995 were followed until five years of age (n = 383,665). Dental admissions were classified by ICD-9 principal diagnosis categories. RESULTS: There were 738 dental admissions for 665 children aged up to five years of Indigenous mothers (n = 20,921). Indigenous children comprised 6.3% of all children having a dental admission in this age group; 3.2% of children with Indigenous mothers had a dental admission compared with 2.7% of non-Indigenous children. Overall, 8.7% (n = 58) of Indigenous children with a dental admission had a birth defect and 5.5% (n = 23) had an intellectual disability (compared to 8.8% and 3.2%). Indigenous children were four times more likely to be diagnosed with oral soft tissue diseases than non-Indigenous children, and less likely to be categorized as having diseases of the dental hard tissues. Indigenous children were more likely to have a longer dental admission. CONCLUSIONS: These analyses provide important findings regarding hospital admissions for Indigenous children. Admissions for disorders of the soft tissues are more common in Indigenous children.

Dental attendance of oral and oropharyngeal cancer patients in a public hospital in Western Australia.

BACKGROUND: Dentists have recently seen the introduction of devices which aim to facilitate early oral cancer detection, sparking interest in opportunistic oral cancer screening. However, concerns have been raised about the lack of regular dental attendance amongst high risk individuals. The purpose of this study was to obtain information pertaining to dental attendance of oral and oropharyngeal cancer patients. METHODS: All records of patients referred to the Oral Medicine Clinic at the Oral Health Centre of Western Australia, between January 2005 and December 2009, from one major teaching hospital were examined. Information extracted included age, gender, smoking status, referral date, tumour type, tumour site, disease stage (TNM classification), and information on dental attendance. Outcomes measured included time (months) since the patient's last dental visit and information concerning regularity of dental attendance. RESULTS: No association was found between dental attendance and gender, smoking, disease stage or age at diagnosis. Most patients had not visited a dentist in the preceding 12 months. The mean date of last dental visit was 5.6 years prior. CONCLUSIONS: More should be done in Australia to encourage patients at high risk of oral cancer to attend the dentist and undergo annual oral soft tissue examination.

Oral cavity squamous cell carcinoma survival by biopsy type: a cancer registry study.

BACKGROUND: Biopsy of a suspected oral squamous cell carcinoma (SCC) is important for diagnosis. Concerns have been raised about the potential for tumour spread by incisional biopsy techniques. This study aimed to investigate the five-year survival and recurrence of oral SCC after incisional and excisional biopsy in total population data available from the Western Australian Cancer Registry (WACR). METHODS: Total population data from the WACR, comprising all primary oral SCC cases diagnosed between 1990 and 1999, were examined. Information extracted included date of birth, gender, biopsy date, biopsy type, disease stage (TNM classification), disease site, date of recurrence and date of death. Records were excluded if the diagnosis was fine needle aspiration based, was not that of oral SCC and if a history was noted of another malignant neoplasm. Incisional and excisional biopsy cases were compared for five-year survival, adjusting for disease stage. RESULTS: No association was found between biopsy type and five-year survival or recurrence amongst individuals with Stage I or II disease. CONCLUSIONS: In this study, biopsy type was not associated with survival of oral SCC patients with Stage I or II disease, adding to the evidence that incisional biopsy of oral SCC can be a safe procedure.

Demographic, health and lifestyle factors associated with dental service attendance by young adults.

BACKGROUND: The aim of this study was to describe the demographic and health and lifestyle factors associated with dental service attendance in the previous 12 months by young Australian adults (18-24 years). METHODS: Population-based data from the 2001 Australian National Health Survey were analysed. Proportions and single associations between variables of interest and dental service attendance were calculated. A logistic regression analysis using significant single association variables was then conducted. RESULTS: Overall, 41 per cent of young adults in this study had visited a dental professional in the previous 12 months. Females, those in cities, those with private insurance, those who spoke languages other than English, those in the highest socioeconomic group and those with healthy behaviours were subgroups most likely to have visited a dental professional. With logistic regression, factors found to be associated with dental services attendance were being female, having private health insurance and low alcohol consumption. CONCLUSIONS: In this study, the proportion of young adults who had visited a dental professional in the previous 12 months was only 41 per cent. It is therefore suggested that oral health policy and promotion activities be encouraged for this group, paying attention to young adults in groups with low attendance.

Health of caregivers in child care.

BACKGROUND: Child care workers play an important role in caring for children attending child care yet there is little research regarding their health. METHODS: The study consisted of focus groups with child care workers and a survey, conducted as part of a larger study known as the Healthy Child Care Study, which focused on children. The study investigated carers working in formal child care [long day care (LDC) and family day care (FDC)]. RESULTS: Questionnaires to caregivers in centres showed that 86% had taken sick leave in the previous year and 75% of staff had taken leave for infectious illness. Carers in FDC reported that 24% had taken sick leave in the previous year and 12% of carers had taken leave for infectious illness. Of responding caregivers from centres, 22% were cigarette smokers while in FDC homes, 8% of carers smoked. In focus groups, carers reported that their major areas of health concern were stress, infectious illness and physical trauma such as lifting injuries. CONCLUSIONS: Child care workers in LDC took more sick leave than those in FDC but this is not necessarily due to more illness. Child care workers are a diverse and important group that require further research.

Absence from childcare for respiratory illness.

BACKGROUND: This population-based study investigated prospectively collected absence for respiratory illness data in two types of formal childcare (centre day care and family day care) in Perth, Western Australia, and factors associated with such absence. METHODS: All centres (n = 11) and 95% of family day care caregivers (n = 130) selected at random from licensing lists agreed to participate. Demographic details were obtained from a parental questionnaire and absences were recorded prospectively. Characteristics of the child and family were described using univariate odds ratios (OR) with 95% confidence intervals (CI). Multivariable analysis including generalized estimating equations was used to investigate having at least one absence for respiratory illness, having two or more absences, and having six or more absences. RESULTS: No statistically significant difference between care types for having had at least one absence episode for respiratory illness (OR 1.37, 95% CI 0.92-2.04) was found. Children who attended care for more days per week (OR 1.40, 95% CI 1.26-1.56) and those in the study for more weeks (OR 1.03, 95% CI 1.01-1.05) were more likely to be absent for respiratory illness. Those children in care for a greater number of hours per day were less likely to be absent (OR 0.88, 95% CI 0.80-0.97). Family history of bronchitis was also associated with absence for respiratory illness (OR 1.86, 95% CI 1.32-2.63). CONCLUSIONS: Statistically significant factors which had an impact on absence for respiratory illness were primarily those relating to the time spent in childcare and to family history of bronchitis.

Edentulism and associated factors in people 60 years and over from urban, rural and remote Western Australia.

BACKGROUND: Edentulism is declining in the aged, in turn increasing demand on dental services. The aim of this study was to describe the pattern of edentulism and associated factors for people 60 years or over in urban, rural and remote Western Australia. METHODS: A cross-sectional telephone interview survey was conducted of 2100 people aged 60 years or over (urban n=800, rural n=800, remote n=500), identified through the State Electoral Roll, who were living in non-institutionalized accommodation in Western Australia and who were able to speak English sufficiently well to be interviewed in English. RESULTS: The main outcome measure was edentulism. The prevalence of edentulism was 25 per cent for people in urban areas, 34 per cent for people in rural areas and 32 per cent for people in remote areas. Respondents aged 60-69 years had less than half the edentulism than respondents aged 80 years or over. Multivariable logistic regression models showed geographic location, age, gender, education and occupation were significantly associated with edentulism. CONCLUSIONS: The percentage of edentulism was highest in rural areas with some clear demographic trends. These future aged cohorts are likely to follow the same patterns of social and geographic disadvantage as found for the current edentate cohort. The results were consistent with other studies while providing state level multivariate results to assist service planning.

Breast cancer and the uptake of mammography screening services by women with intellectual disabilities.

BACKGROUND: It is estimated that approximately 50% of women in Australia with intellectual disability will live to 70 years of age and as a result many will fall within the age group at highest risk for breast cancer (50-69 years). METHODS: Subjects were identified through the Western Australia Disability Services database. To determine the number of women diagnosed with breast cancer during the period 1982-2000, individual records (n = 2,370) were linked to the Western Australia Cancer Registry and the Mammography Screening Registry. RESULTS: The incidence of breast cancer among women with intellectual disability was 64.0 per 100,000 person-years, by comparison with 146.7 per 100,000 person-years in the general population. The uptake of breast cancer screening was examined in a subgroup of 380 women, 34.7% of whom had used mammographic screening, as opposed to 54.6% screening uptake in the general population. Failure to use screening services was highest in women who were unmarried, and was positively associated with severity of intellectual disability, presence of physical disabilities, and urban residence. CONCLUSIONS: The lower incidence of breast cancer in women with intellectual disability may in part be attributable to decreased life expectancy, but it also appears to reflect significant under utilization of the readily available screening services.

Dental visits by Australian preschool children.

OBJECTIVE: To provide population-based data on dental visits in preschool children, to assist in the planning of such services and preventive programs. METHODOLOGY: Dental visits in young children are described and associated factors are investigated using data from the 1995 National Health Survey. RESULTS: Thirty-eight per cent of children aged 3-4 years had ever visited a dental professional with 31% having visited a dental professional in the previous 12 months (total n = 1596). Factors associated with having ever visited a dental professional included age in years (chi2 = 74.16, P < 0.0001), state of residence (chi2 = 25.81, P= 0.0005) and private health insurance (chi2 = 7.96, P= 0.005). Similar factors were associated with visits in last 12 months. Western Australia had the lowest proportion of preschool children aged 3-4 years having ever visited a dental professional (29%) while South Australia had the highest proportion (48%). The major reasons given for dental visits were check-up and fillings. CONCLUSION: Data regarding children not as likely to attend dental services can be used to target services and assist in ensuring preschool children receive appropriate dental care.

Arthritis and use of dental services: a population based study.

BACKGROUND: Rheumatoid arthritis (RA) and osteoarthritis (OA) are chronic systemic conditions that can have a profound effect on oral health as the result of physical disability, immunosuppressant and other medications and autoimmune disease. However, there is insufficient information available on the use of dental services by the people suffering from RA or OA. The purpose of this study was to investigate dental visits and factors associated with dental attendance in those with RA and OA in order to improve access to dental care in these groups. METHODS: The study used population based data from the 1995 National Health Survey (total n=53828). The main variables of interest were reported RA (n=1193) and OA (n=3091) and the main outcome variable was having visited a dental professional in the previous 12 months. Chi-square analysis was performed using SAS software. RESULTS: The proportion of people visiting a dental professional in previous 12 months was significantly less in both RA and OA respondents compared to non-arthritic respondents. Both males and females with RA and OA were found to be less likely to have visited a dental professional when compared to general population (p=0.001 in each case). Furthermore, the findings have revealed that RA and OA patients living in metropolitan centres were more likely to have a dental visit than those living in rural or remote areas (p=0.001 in each case). CONCLUSIONS: When compared to non-arthritic subjects, all patients with RA and OA were less likely to receive dental care, in particular preventive care. This is especially important in patients with Sjogren's Syndrome and those who are immunosuppressed.

An investigation into the use of pilocarpine as a sialagogue in patients with radiation induced xerostomia.

BACKGROUND: Radiation therapy to the head and neck region can be an effective form of treatment for malignancies. Unfortunately damage to salivary glands may occur. Treatment of resultant dry mouth is at present very poor. The purpose of this pilot study was to investigate whether pilocarpine dissolved in artificial saliva and administered in a mouth spray would be effective in relieving such symptoms. METHODS: Twenty-three patients with radiation induced hyposalivation were recruited for this randomized, double-blind investigation. Subjects were randomly allocated to placebo or control medicaments used for eight weeks. All subjects were evaluated for the severity of their xerostomia associated symptoms prior to administration of the spray and again eight weeks later. RESULTS: The questionnaire and the visual analogue scale did not reveal any improvements in the dry mouth symptoms between cases and controls. Side-effects were reported among cases, mostly mild and tolerable. All patients taking pilocarpine (with base salivary flow rates > 0ml/min) demonstrated improvement in stimulated and unstimulated salivary flow rates. Candida counts decreased among the cases and controls although decrease among the cases was much greater. CONCLUSIONS: The results obtained indicate that provided residual functioning salivary tissue exists, pilocarpine used as formulated is effective and warrants further investigation.

Average recovery time from a standardized intravenous sedation protocol and standardized discharge criteria in the general dental practice setting.

Intravenous sedation has been used in dentistry for many years because of its perceived advantages over general anesthesia, including shorter recovery times. However, there is limited literature available on recovery from intravenous dental sedation, particularly in the private general practice setting. The aim of this study was to describe the recovery times when sedation was conducted in private dental practice and to consider this in relation to age, weight, procedure type, and procedure time. The data were extracted from the intravenous sedation records available with 1 general anesthesia-trained dental practitioner who provides ambulatory sedation services to a number of private general dental practices in the Perth, Western Australia Metropolitan Area. Standardized intravenous sedation techniques as well as clear standardized discharge criteria were utilized. The sedatives used were fentanyl, midazolam, and propofol. Results from 85 patients produced an average recovery time of 19 minutes. Recovery time was not associated with the type or length of dental procedures performed.
