A scoping review of caries risk management protocols in Australia and New Zealand.

To identify and map the caries risk management protocols with multiple strategies, which were used in Australia and New Zealand and reported in the existing literature, a scoping review was carried out by electronically searching PubMed, Web of Science, Scopus, Embase and Dentistry and Oral Science. Studies on caries risk management protocols, written in English, limited to Australia and New Zealand and published up to March 2018 were included in the review. There was no restriction on participants' age. Of 257 studies identified, seven were included in the review. These seven studies were reported in Australia and all but six were based on the caries management system (CMS). There were two descriptive studies, one 3-year multicentre cluster randomized controlled trial (RCT), one 2 to 4-year post-RCT follow-up and two cost-effective evaluations based on Markov decision analytic models. While concentrating on assessing individual behavioural risk factors for dental caries, studies indicated that the CMS would be more cost-effective if its protocol was properly adhered to. Future studies on caries risk management protocols are suggested to consider both the individual characteristics and the social context of different population groups in view of enhancing the effectiveness of oral care.

Health behaviours and quality of life in independently living South Australians aged 75 years or older.

BACKGROUND: This study evaluated the associations between oral and general health behaviours, self-reported health and quality of life of adults aged 75 years or older living independently in South Australia. METHODS: A cross sectional study based on a self-report mailed questionnaire was conducted in 590 independently living adults aged 75 years or older. Self-ratings of oral health and general health were assessed using single-item global ratings. Quality of life was measured using the Oral Health Impact Profile and the EuroQol instrument for health utility. RESULTS: The overall response rate was 78%. The current analyses were restricted to 354 dentate older adults. Increasing age and being female were negatively associated with EuroQol scores. Good self-rated oral and general health were more prevalent in participants with higher social status who also had lower oral health impact and higher EuroQol scores. Good self-rated oral and general health were less prevalent while oral health impact was greater in participants who ate few fruits, vegetables or dairy products. CONCLUSIONS: Self-rated health and quality of life were poor in older adults with inadequate fruit/vegetables/dairy intake and lower social status. These findings suggest that nutrition and socioeconomic factors may be important to the oral and general health of adults aged 75 years or older.

Oral health behaviours and perceptions reported by Indigenous Australians living in Darwin, Northern Territory.

OBJECTIVE: To describe the reported oral health behaviours and perceptions of Indigenous Australians living in Darwin, Northern Territory and to compare those with estimates for Darwin and Australia derived from the National Survey of Adult Oral Health (NSAOH). PARTICIPANTS: A total of 181 Indigenous Australians aged 22 years and over living in Darwin, participating in screening for a wider randomised clinical trial, were included. METHOD: Information on socio-demographic characteristics, oral health status including oral health behaviours and perceptions was collected using a questionnaire. Differences between the Darwin study (DS) participants and Australians in NSAOH were made based on non-overlapping 95% confidence intervals. RESULTS: Almost 72% of DS participants had last seen a dentist over a year earlier, compared to 47% and 39% of NSAOH Darwin and Australian participants, respectively. A higher proportion of DS participants usually visited a dentist because of a problem than NSAOH Darwin and NSAOH Australian participants. A higher proportion of DS participants had avoided or delayed a dental visit because of cost than NSAOH participants. Over three times as many DS participants rated their oral health as fair/poor compared to NSAOH participants. A higher proportion of DS participants had perceived gum disease and one or more symptoms of gum disease than NSAOH participants. A higher proportion of DS participants experienced toothache, felt uncomfortable about appearance of their mouth and avoided eating because of oral problems than NSAOH participants. CONCLUSIONS: A higher proportion of Indigenous Australians living in Darwin presented with non-optimal oral health behaviours and perceptions compared with both the Darwin and Australian general populations.

Socio-demographic risk indicators for tooth mortality in rural Sri Lankans.

To explore the socio-demographic factors associated with tooth loss in rural inhabitants of Sri Lanka, a random sample of 2178 males aged 20-60 years was selected using multi-stage cluster sampling procedure. The number of missing and present teeth was recorded excluding third molars and the subjects were interviewed to elicit socio-demographic information as well as oral hygiene and tobacco consumption habits. The mean number of teeth lost in the sample was 5.17 +/- 5.43. Tooth loss increased significantly with age. Sinhalese had significantly fewer lost teeth (5.05 +/- 5.38) compared to Tamils (6.54 +/- 6.18) and Muslims (6.02 +/- 5.21) whereas education, income, oral hygiene practices and tobacco use were significantly associated with tooth loss in the bivariate analysis. A forward stepwise multiple regression analysis revealed that age, Muslim ethnicity and quantified tobacco use were positively associated with tooth loss while better socio-economic conditions and good oral hygiene habits were negatively linked with tooth mortality independent of other factors. Age, Muslim ethnicity, quantified tobacco use, income, education, brushing frequency and substance used for cleaning had significantly affected tooth loss. Quantified tobacco use and oral hygiene may be regarded as modifiable socio-demographic risk indicators associated with tooth mortality in Sri Lankans.
