RESUMO
AIM: Oral health conditions are highly prevalent among former refugees; however, little is known about their experiences of accessing dental care. We aimed to explore Syrian former refugees' experiences of oral healthcare in New Zealand. METHOD: Thirty-nine Syrian former refugees resettled in Dunedin, New Zealand participated in nine focus group discussions. The interviews were audio-recorded, transcribed verbatim and thematically analysed. RESULTS: Almost all participants reported motivation to care for their teeth but multiple factors facilitated or hindered their ability to address their oral health needs, including financial factors, communication issues and dental care provider cultural safety. Most participants arrived with high expectations of New Zealand's health system. CONCLUSION: Oral healthcare providers and policymakers need to expect and accept their patients' past experiences and emotions, and consider their cultures, languages and backgrounds.

OBJECTIVES: The objective of the study was to describe the occurrence and associations of oral self-care by dependent older New Zealanders. BACKGROUND: Dependent older adults who require some level of assisted daily care have been shown to have poorer oral health than their independent counterparts, yet national estimates are lacking. MATERIALS AND METHODS: A secondary analysis was conducted of data from New Zealand's 2012 Older People's Oral Health Survey, a national survey that interviewed and examined a representative sample of 2,218 dependent older adults living in aged residential care or receiving home-based care. Survey data were weighted for statistical analyses, and modelling was carried out using a modified Poisson approach. RESULTS: Overall, 59.5% (95% CI: 55.1, 63.7) of participants brushed their teeth twice a day, with this rate higher among women, Asians and those without cognitive or physical impairment. Cleaning interdentally at least once a week was less common than brushing, at 25.9% (95% CI: 21.5, 30.9), and that proportion was significantly lower among those with higher dependency or who were cognitively or physically impaired. Almost 9 in 10 (87.8%; 95% CI 83.1, 91.4) used fluoride toothpaste, and adults of high socio-economic status had lower rates of fluoride toothpaste use. Only 15.0% (95% CI 12.4, 18.0) used mouthwash, with this being most prevalent in Pasifika. More than half of those who wore dentures also wore them at night. CONCLUSION: Oral self-care was sub-optimal among dependent older New Zealanders. Improving the situation should be a high priority.

OBJECTIVES: To compare the clinical validity of the three approaches in residential care facility residents. BACKGROUND: In NZ residential care facilities, the interRAI assessment tool is used by trained registered nurses for assessing oral status when new residents are admitted, but its validity has been questioned. Although Locker's global oral health item has been used to measure oral health in surveys and health services research, it is not routinely used in care facilities, yet its clinical validity has been demonstrated in population-based samples. Self-perceived oral health need may also be useful. MATERIALS AND METHODS: Using a secondary analysis of clinical and self-reported data from a national survey of nursing home residents (the 2012 New Zealand Older People's Oral Health Survey, or OPOHS), we compared the validity of Locker's item, the interRAI tool and self-reported treatment need for identifying three key clinical indicators of poor oral health among dentate older adults; those were coronal caries (3+ teeth affected), root caries (1+ teeth affected) and xerostomia. Analyses were conducted using STATA, and survey weighting was used to obtain estimates for a source population of 25-843 individuals. RESULTS: The prevalence of 3+ teeth with coronal caries was 28.7% (23.9, 34.0), the prevalence of 1+ teeth with root caries was 33.7% (28.7, 39.0), the prevalence of xerostomia was 23.1% (18.4, 28.3). Marked gradients in prevalence risk ratio were seen across different categories of Locker's global oral health item and the interRAI assessment tooth for coronal caries and xerostomia. Locker's global oral health item gave a better fitting model and was more discriminative in detecting coronal caries than the interRAI assessment tool (Lockers AIC = 0.76, interRAI AIC = 0.81). None of the approaches was particularly discriminative for root surface caries experience. CONCLUSION: Self-reported approaches are discriminative for poor oral health. Standardised assessment tools used in residential care facilities should consider including a self-assessment component such as Locker's global oral health item.
RESUMO
BACKGROUND: There have been no detailed descriptions of residual dentition patterns among older people living in the community. OBJECTIVES: To describe the residual dentition and associated oral health-related quality of life among older New Zealanders living in their own homes with government-funded assistance. MATERIALS AND METHODS: Using nationally representative data, we determined the residual dentition arrangement and Kennedy classification for each dental arch. Individuals were categorised according to their maxillary-mandibular dental configuration and prosthesis use. Data were weighted to make the estimates generalisable to the source population. RESULTS: Of the 895 clinically examined participants, 47.8% were dentate. One-quarter of those had maxillary tooth-bound saddles opposing a partially dentate mandible. Pasifika (people of Pacific Islands ethnicity) were most likely to have retained all of their dentition, while only the Maori ethnic group had no participants with a dentate arch. Only one in three of those with partially dentate upper and lower arches wore any maxillary denture; one in ten wore some form of mandibular denture. Partial dentures were common among those with an opposing edentulous jaw. Maxillary partial dentures were twice as common as their mandibular counterparts. CONCLUSION: Residual dentition patterns in older people are diverse and complex, and meeting their prosthodontic needs is not straightforward.

With a reported prevalence between 20% and 30%, dry mouth is more common among older people than any other age group. The major risk factor for dry mouth is polypharmacy. Older people take more medications than any other age group, not only for symptomatic relief of various age-associated chronic diseases, but also to reduce the likelihood of the complications that may arise from those conditions. Most aged care residents take even more medications than older people who are living in their own homes. The greater the number of medications taken, the greater the associated anticholinergic burden, and the more likely it is that the individual will suffer from dry mouth. The condition not only affects the dentition and ability to wear dentures, but also the sufferers' quality of life. Treating dry mouth is a considerable challenge for clinicians. As medication use is by far the most important risk factor, there is a need for pharmacists, doctors and dentists to work together to prevent this from occurring. Medication review and deprescribing is a key strategy, but there have not yet been any randomised control trials of its efficacy in reducing the occurrence of dry mouth.
RESUMO
BACKGROUND: Previous studies of the nutritional status of older individuals have used measures such as plasma vitamin and mineral levels, which can be difficult to interpret. The relationship between nutrition and dentition has been limited to studying exposures such as the number of posterior occluding pairs of teeth, edentulousness, and the number of natural teeth. OBJECTIVES: To investigate the association between dentition status and nutritional status in a national survey of older New Zealanders living in aged residential care facilities. MATERIAL AND METHODS: Secondary analysis of clinical oral status and nutrition data collected in 2012 in New Zealand's Older People's Oral Health Survey. The validated Mini Nutritional Assessment short format was used to categorize participants as "normal nutritional status," "at risk of malnutrition" or "malnourished." RESULTS: Just under half of older New Zealanders living in aged residential care facilities were classified as either at risk of malnutrition or malnourished (with about one in sixteen in the latter category). The prevalence of malnutrition was higher among those in hospital-level and psychogeriatric-level care, as well as in those of high socioeconomic status. Individuals who were at risk of malnutrition had the most untreated dental caries and untreated coronal caries. Relative to their counterparts in nursing-home-level care, dentate individuals in hospital-level care were 2.4 times-and those in psychogeriatric-level care were 2.8 times-as likely to be malnourished or at risk of it. CONCLUSIONS: Just under half of the New Zealanders living in aged residential care were at risk of malnutrition or were malnourished. Greater experience of untreated dental caries was associated with a higher rate of being malnourished or at risk of it. Poorer cognitive function and greater dependency were important risk indicators for malnutrition.

BACKGROUND: Medication-induced xerostomia is common in older people. We investigated medication use and xerostomia in dependent older New Zealanders. METHODS: Medication and xerostomia data analysed from a nationally representative survey of dependent older people. Automatic interaction detection analysis identified medications combinations most strongly associated with xerostomia, and then xerostomia was modelled. RESULTS: Just over half were taking five to nine different medications; one in five was taking 10+. Xerostomia prevalence (29.4%; 95% confidence interval 26.5, 32.5) was higher among the latter and lowest in psychogeriatric patients. After controlling for age and sex, it was higher among people taking any antidepressant, and higher still with a tricyclic antidepressant and either a steroid or an anticholinergic, or among people taking a bronchodilator without prophylactic aspirin. CONCLUSIONS: Health practitioners should work together to ensure that those with xerostomia are managed in a timely and appropriate manner. Medication review is an important component of that.

OBJECTIVES: To investigate the clinical validity of self-rated oral health among older New Zealanders in aged residential care. MATERIAL AND METHODS: A national survey of oral health in aged residential care was carried out throughout New Zealand. Self-rated oral health was measured using Locker's global item and clinical examinations carried out by calibrated examiners. Analyses used survey weights. RESULTS: Consistent gradients were observed across the self-rated oral health categories in the mean number of decayed teeth (whether coronal or root surface caries), mean number of filled teeth (albeit in the opposite direction), and in the mean number of fillings needed. Consistent gradients were also seen in the same categories when comparing the current oral health status to their oral health status a year previous. No gradients in periodontal status were apparent. CONCLUSIONS: The older population in aged residential care can validly self-rate their oral health, although further investigation of periodontal status is warranted.

BACKGROUND: Descriptions of the older population's dentition status are usually limited to indicators such as the edentulous proportion, the mean number of restored and missing teeth, and the proportion with a functional dentition, with very few reports describing in detail the nature of the residual dentition. OBJECTIVES: This study described the residual dentition among older New Zealanders living in residential aged care facilities. MATERIAL AND METHODS: Using national data from the Older People's Oral Health Survey, we determined the residual dentition arrangement and Kennedy classification for each dental arch. Individuals were categorised according to their maxillary-mandibular dental configuration. Data were weighted to make the estimates generalisable to the source population. RESULTS: Among the dentate 45% of the 987 clinically examined participants, the most prevalent configuration was maxillary tooth-bounded saddles against a partially dentate lower (24.7%; 95% CI: 20.4, 29.7). More younger participants generally had less tooth loss experience and had higher prevalence of Kennedy Classes II, III and IV. There were few sex differences, although more females had a fully dentate arch. Marked ethnic differences were observed: Maori were up to eight times as likely to have only mandibular anterior teeth remaining. Upper dentures were worn more than their lower counterpart. Age, sex and ethnic characteristics were associated with particular residual teeth configurations. CONCLUSIONS: Having various degrees of tooth loss was the norm, with the upper tooth-bounded saddles against any partially dentate lower combination most common, and limited to females. An edentulous maxilla opposed by some standing teeth was observed in over one-quarter of the population, and most common among Maori and those who were older. Maxillary prostheses were much more common than mandibular ones. Caring for dentate older people in aged residential care is likely to be complicated by the wide range of dentition configurations.

OBJECTIVES: To investigate clinical oral disease and its association with cognitive function and dependency among older New Zealanders in residential aged care. MATERIAL AND METHODS: National survey of oral health in aged residential care throughout New Zealand. We classified residents into 1 of 3 levels of care: "low dependency care (or assisted living)"; "high dependency care"; or "specialist dementia care/psychogeriatric care." The Abbreviated Mental Test characterised cognitive function as "unimpaired" (scores of 7-10), "moderately impaired" (4-6) or "severely impaired" (0-3). Intra-oral examinations were conducted, along with a computer-assisted personal interview. RESULTS: Most of the 987 clinically examined participants were either at low or high dependency care level, with another 1 in 6 in psychogeriatric care. Almost half overall had severely impaired cognitive function. Just under half of the sample had 1 or more natural teeth remaining. Negative binomial regression modelling showed that the number of carious teeth was lower among women and higher among those who were older, those with more teeth and in those with severely impaired cognitive function. Oral debris scores (representing plaque biofilm and other soft deposits on teeth) were higher in men, those with more teeth, and in those with severely impaired cognitive function. CONCLUSIONS: Impaired cognitive function is a risk indicator for both dental caries and oral debris in aged residential care.
RESUMO
INTRODUCTION: This paper reports on a new methodology to objectively study the world in which children live. The primary research study (Kids'Cam Food Marketing) illustrates the method; numerous ancillary studies include exploration of children's exposure to alcohol, smoking, "blue" space and gambling, and their use of "green" space, transport, and sun protection. METHODS: One hundred sixty-eight randomly selected children (aged 11-13 years) recruited from 16 randomly selected schools in Wellington, New Zealand used wearable cameras and GPS units for 4 days, recording imagery every 7 seconds and longitude/latitude locations every 5 seconds. Data were collected from July 2014 to June 2015. Analysis commenced in 2015 and is ongoing. Bespoke software was used to manually code images for variables of interest including setting, marketing media, and product category to produce variables for statistical analysis. GPS data were extracted and cleaned in ArcGIS, version 10.3 for exposure spatial analysis. RESULTS: Approximately 1.4 million images and 2.2 million GPS coordinates were generated (most were usable) from many settings including the difficult to measure aspects of exposures in the home, at school, and during leisure time. The method is ethical, legal, and acceptable to children and the wider community. CONCLUSIONS: This methodology enabled objective analysis of the world in which children live. The main arm examined the frequency and nature of children's exposure to food and beverage marketing and provided data on difficult to measure settings. The methodology will likely generate robust evidence facilitating more effective policymaking to address numerous public health concerns.

OBJECTIVES: We explored the following research questions: (i) what challenges do dentists face when providing oral health care to dependent older adults; and (ii) to overcome those challenges, what recommendations would dentists providing care give those planning and implementing oral health policy and services for dependent older adults? BACKGROUND: The dentate older population is steadily increasing, and about half will end up in residential care, where dental caries rates over time are at least twice as great as those observed elsewhere. MATERIALS AND METHODS: A qualitative study was used, with semi-structured interviews conducted by a single interviewer. Dental examiners in a recent national survey of oral health in dependent older people in New Zealand were interviewed about their experiences and perspectives of that. RESULTS: The challenges participants identified stemmed from three areas - the patient, the care facility and the oral health sector. To address those challenges, the participants recommended actions at the patient, system and sector levels. Each of the challenges and recommendations had a number of subthemes. Overall, the dentists felt that it is a very complex situation urgently requiring policy development, cross-sectoral collaboration and upskilling of the dental profession, carers, the private sector and the State to ensure a care environment which supports achieving and maintaining oral health among frail elders. CONCLUSIONS: Urgent attention to frail older New Zealanders' oral health is needed. Such attention needs to focus on not only the narrow dental clinical preventive and therapeutic implications of those needs, but also on the broader health system and policy development challenges.

BACKGROUND: Economic changes and policy reforms, consistent with economic globalization, in New Zealand in the mid-1980s, combined with the recent global demand for dairy products, particularly from countries undergoing a 'nutrition transition', have created an environment where a proportion of the New Zealand population is now experiencing financial difficulty purchasing milk. This situation has the potential to adversely affect health. DISCUSSION: Similar to other developed nations, widening income disparities and health inequalities have resulted from economic globalization in New Zealand; with regard to nutrition, a proportion of the population now faces food poverty. Further, rates of overweight/obesity and chronic diseases have increased in recent decades, primarily affecting indigenous people and lower socio-economic groups. Economic globalization in New Zealand has changed the domestic milk supply with regard to the consumer and may shed light on the link between globalization, nutrition and health outcomes. This paper describes the economic changes in New Zealand, specifically in the dairy market and discusses how these changes have the potential to create inequalities and adverse health outcomes. The implications for the success of current policy addressing chronic health outcomes is discussed, alternative policy options such as subsidies, price controls or alteration of taxation of recommended foods relative to 'unhealthy' foods are presented and the need for further research is considered. SUMMARY: Changes in economic ideology in New Zealand have altered the focus of policy development, from social to commercial. To achieve equity in health and improve access to social determinants of health, such as healthy nutrition, policy-makers must give consideration to health outcomes when developing and implementing economic policy, both national and global.
