The oral health of ageing baby boomers: a comparison of adults aged 45-64 and those 65 years and older.

OBJECTIVES: To compare the oral health status of adults aged 45-64 (baby boomers) and those aged 65 and older. METHODS: An observational, cross-sectional survey of adults living independently in rural and urban settings in Nova Scotia, Canada was conducted. Using random digit dialing, calibrated interviewers completed a telephone survey, and clinicians calibrated to WHO standards conducted clinical examinations. Weighting was used to correct for sampling bias. RESULTS: 747 community dwelling adults completed both the clinical exam and the questionnaire (n=411, age 45-64; n=336, age 65 or older). Rates of edentulism were low (2.6% aged 45-64; 15.7% aged 65+; p<0.001). Untreated root caries was greater in the older dentate group (19.7 vs. 10.1%; p<0.001). Being 65 years of age or older was identified as a predictor of increased decayed, missing, filled teeth, presence of decayed and/or filled roots and presence of attachment loss≥4 mm, but was not a significant predictor of presence of untreated coronal caries. CONCLUSIONS: A falling rate of edentulism and a higher risk for root caries with increasing age may predict the need for more complex dental care as our population ages.

Oral health-related quality of life in an aging Canadian population.

BACKGROUND: The purpose of the study is to describe the impact of oral health-related quality of life (OHRQoL) on the lives of pre-seniors and seniors living in Nova Scotia, Canada. METHODS: This cross-sectional study involved 1461 participants, grouped by age (pre-seniors [45-64] and seniors [65+]) and residential status (long-term care facility [LTC] or community). OHRQoL was measured using the 14-item Oral Health Impact Profile questionnaire (OHIP-14) in a random digit dialing telephone survey (for community residents) or a face-to-face interview (for LTC residents). Intra-oral examinations were performed by one of six dentists calibrated to W.H.O. standards. RESULTS: Approximately one in four pre-seniors and seniors reported at least one OHRQoL impact 'fairly/very often'. The most commonly reported impacts were within the dimensions 'physical pain' and 'psychological discomfort'. It was found that 12.2% of LTC residents found it uncomfortable to eat any foods 'fairly/very' often compared to 7.7% in the community, and 11.6% of LTC residents reported being self-conscious 'fairly/very often' compared to 8.2% in the community. Of those residing in the community, pre-seniors (28.8%) reported significantly more impacts than seniors (22.0%); but there were no significant differences in OHRQoL between pre-seniors (21.2%) and seniors (25.3%) in LTC. Pre-seniors living in the community scored significantly higher than community dwelling seniors on prevalence, extent and severity of OHIP-14 scores. Logistic regression revealed that for the community dwelling sample, individuals living in rural areas in addition to those being born outside of Canada were approximately 2.0 times more likely to report an impact 'fairly/very often', whereas among the LTC sample, those having a high school education or less were 2.3 times more likely to report an impact. CONCLUSIONS: Findings indicate that the oral health and OHRQoL of both pre-seniors and seniors in LTC residents is poor. Community dwelling pre-seniors have the highest prevalence rate of oral impacts.

Oral health status of long-term care residents-a vulnerable population.

OBJECTIVE: To conduct an observational, cross-sectional survey of the oral health status of adults ≥ 45 years of age in rural and urban long-term care (LTC) facilities in Nova Scotia, Canada. METHODS: Residents capable of informed consent were recruited by LTC staff in a stratified random sample of LTC facilities. Calibrated personnel administered standard clinical and quality-of-life instruments. RESULTS: Of the 335 adults (74% female) surveyed (mean age 80.8 ± 11.6 years), only 25% reported having regular dental care. Although 76% described their oral health as good or excellent, 41% were edentulous, 41% had some mucosal abnormality, 36% reported xerostomia and 25% had perceived or self-reported untreated dental conditions. Most mandibular dentures were nonretentive (59%) and almost half were unstable (49%). Among the dentate, 51% had untreated coronal caries, 44% had untreated root caries and 67% had attachment loss of ≥ 4 mm at ≥ 1 site. Predictors of coronal decay were a debris score ≥ 2 (adjusted odds ratio [adj OR] = 2.12; p = 0.045) or a history of smoking (adj OR = 1.02 per year of smoking; p = 0.024). Predictors of root caries were participants' perceiving a need for dental treatment (adj OR = 2.56; p = 0.015) or a history of smoking (adj OR = 1.02 per year of smoking; p = 0.026). CONCLUSIONS: This epidemiologic study of the oral health of LTC residents revealed a high prevalence of untreated oral disease and low use of oral care services, highlighting the need for better access to oral care for this population.

Enhancing the quality of life in elderly women through a programme to improve the condition of salivary hypofunction.

OBJECTIVE: The purposes of this study were to examine the effects of oral exercise intended to improve the function of the oral cavity in the elderly and their quality of life to pave the way for the development of oral-health promotion programmes geared towards the elderly. METHODS: The subjects were 78 female Koreans who resided in Seoul and were aged 65 years and older. During a 3-month period, an oral function promotion programme was conducted twice a week, between 10.00 am and 12.00 pm, applying oral exercise suggested by a Japanese public health centre. A survey was conducted by interviewing the selected women to determine the state of their subjective dry mouth, quality of life related to oral health and jaw functional limitation. Their opening, unstimulated whole saliva and pronunciation speed were measured before and after the oral function exercise programme. RESULTS: The subjects showed a significant improvement in subjective dry mouth symptoms, relevant behaviour, the level of discomfort caused by dry mouth and subjective jaw functional limitation during mastication and swallowing and emotional expression after receiving the oral exercise. After the oral exercise, there was a significant increase in mouth opening, unstimulated whole saliva and speaking speed ('patakala' pronunciation) after oral exercise. There was also significant progress in their quality of life related to oral health. Overall improvement in subjective dry mouth symptoms and relevant behaviour over time after oral exercise had a positive correlation with the level of improvement in discomfort triggered by dry mouth and mastication. The level of improvement in OHIP-14 had a positive correlation with the level of overall improvement in dry mouth symptoms and behaviour, the level of improvement in discomfort by dry mouth and that in mastication and swallowing. CONCLUSION: This study showed the effects of the oral function promotion programme and correlation of oral condition and oral health-related quality of life. It is suggested that this oral function promotion programme has positive effects on both objective and subjective oral conditions. It is strongly recommended that this programme, along with other oral health promotion programmes, be implemented to improve oral function and oral health-related quality of life for the elderly.

Assessing the oral health of an ageing population: methods, challenges and predictors of survey participation.

OBJECTIVES: To examine predictors of participation and to describe the methodological considerations of conducting a two-stage population-based oral health survey. METHODS: An observational, cross-sectional survey (telephone interview and clinical oral examination) of community-dwelling adults aged 45-64 and ≥65 living in Nova Scotia, Canada was conducted. RESULTS: The survey response rate was 21% for the interview and 13.5% for the examination. A total of 1141 participants completed one or both components of the survey. Both age groups had higher levels of education than the target population; the age 45-64 sample also had a higher proportion of females and lower levels of employment than the target population. Completers (participants who completed interview and examination) were compared with partial completers (who completed only the interview), and stepwise logistic regression was performed to examine predictors of completion. Identified predictors were as follows: not working, post-secondary education and frequent dental visits. CONCLUSION: Recruitment, communications and logistics present challenges in conducting a province-wide survey. Identification of employment, education and dental visit frequency as predictors of survey participation provide insight into possible non-response bias and suggest potential for underestimation of oral disease prevalence in this and similar surveys. This potential must be considered in analysis and in future recruitment strategies.

From clinician to researcher--a first-hand account.

While teaching and clinical care may be somewhat intuitive, research is much less so, and a lack of research experience or opportunity to do research can be frustrating to the faculty member who is trying to become well-rounded. In an effort to ease the transition from clinical teacher to clinical researcher, the faculty of dentistry at Dalhousie University has developed a research mentorship program. The purpose of this paper is to report on the opportunities and challenges that 2 dental clinicians experienced when they participated in the pilot phase of an epidemiologic survey of the oral health status of seniors. In their academic role, these 2 clinical examiners, who were full-time faculty members, concentrated on classroom and clinical teaching. Although neither had previous clinical research experience, both were interested in broadening their horizons by engaging in research in the hope of attaining a variety of positive outcomes.

Oral and pharyngeal cancer: knowledge and opinions of dentists in British Columbia and Nova Scotia.

Oral and pharyngeal cancers are largely preventable and can be successfully treated when diagnosed at an early stage. Dentists in British Columbia and Nova Scotia were surveyed regarding their knowledge and opinions about oral and pharyngeal cancer. In February 1998 a pretested 41-item survey was mailed to a random sample of dentists in British Columbia and the population of dentists in Nova Scotia. A reminder postcard and one additional mailing were sent to nonrespondents. Of the 670 dentists supplying usable responses (response rate 55.2%) only 56.7% agreed that their knowledge of the subject was current. Most dentists correctly identified tobacco use (99.4%) and alcohol use (90.4%) as risk factors, but fewer correctly identified factors such as the use of spicy foods (57.0%) and poor oral hygiene (46.3%) as not being risk factors. Only 42.5% identified both erythroplakia and leukoplakia, in that order, as the conditions most likely associated with oral cancer. Indices of risk and diagnostic knowledge were constructed by summing the number of correct responses to items in each domain. On 16 risk factors the mean correct score was 9.2, and on 14 diagnostic procedures the mean correct score was 10.0. Only 38.5% of dentists had consistent levels of knowledge on both indices. Differences between the provinces were statistically significant (p < 0.01) for only 2 knowledge items. About three-quarters of all dentists (77.0%) were interested in taking continuing education courses. Dentists in British Columbia and Nova Scotia could benefit from undergraduate and continuing education courses to increase their knowledge of risk and diagnostic factors for oral cancer.

Oral and pharyngeal cancer: practices and opinions of dentists in British Columbia and Nova Scotia.

Oral and pharyngeal cancers are associated with high mortality rates, a situation usually attributed to late-stage diagnosis. Dentists in British Columbia and Nova Scotia were surveyed regarding their practices and opinions related to oral and pharyngeal cancer. In February 1998 a pretested, 41-item survey was mailed to a random sample of dentists in British Columbia (n = 817) and the population of dentists in Nova Scotia (N = 423). A reminder postcard and one additional mailing were sent to nonrespondents. Of the 670 dentists supplying usable responses (response rate 55.2%), only 56.7% agreed that their knowledge of the subject was current. Of 8 health history items, dentists assessed 5 on average, with most (88.0%) asking about the patients' current use of tobacco. A total of 72.7% of the responding dentists performed an oral cancer examination for all edentulous patients at every appointment, but 10.9% never did so. Similarly, 70.7% of the dentists always provided an oral cancer examination at the initial appointment for patients 40 years of age and older, but 9.8% never did so. Undergraduate training related to oral cancer examination was reported as good by only 52.2% of the dentists. About three-quarters of all dentists (77.0%) were interested in taking continuing education courses on this subject. Differences between the 2 provinces were not statistically significant (p > 0.01). Dentists in British Columbia and Nova Scotia could benefit from undergraduate and continuing education courses to increase their knowledge of health history assessment, examination for oral and pharyngeal cancers, and risk reduction strategies, such as counselling about tobacco cessation.

Maryland dental hygienists' knowledge, opinions and practices regarding dental caries prevention and early detection.

PURPOSE: The purpose of this study was to assess Maryland dental hygienists' knowledge, practices and opinions regarding dental caries prevention and early detection. METHODS: A 30 item survey was mailed to 1,258 Maryland dental hygienists. Two follow-up mailings and email reminders were sent. RESULTS: The response rate was 43% (n=540). Nearly all respondents were female (98%), and 58% practiced in solo settings. Knowledge and certainty of knowledge were moderate: sealants are needed regardless of topical fluoride use (55% certain, 40% less certain), newly erupted permanent molars are the best candidates for sealants (54%, 36%) and professionally applied fluorides are desirable in areas without fluoridated water (55%, 36%). Fewer were certain that incipient lesions can be remineralized before cavitation (23%, 69%), and dilute, frequently administered fluorides are more effective in caries prevention than concentrated, less frequently administered fluorides (6%, 24%). Opinions regarding effectiveness of protocols for 2 age groups from 6 months to 6 years, the challenges of early childhood caries (ECC), prevention practices regarding sealant and topical fluoride applications varied widely. Eighty-nine percent reported routinely assessing dental caries risk factors of child patients and 90% were interested in continuing education courses. There were no significant differences between different types of practice settings, year of graduation, race/ethnicity or gender. CONCLUSION: Knowledge of recommended guidelines for fluoride and sealant application support clinical decision-making and self-care counseling. Misinformation and lack of understanding of current research and recommendations identify a need for educational interventions in undergraduate dental hygiene programs and through continuing education for practicing hygienists.

Action planning for daily mouth care in long-term care: the brushing up on mouth care project.

Research focusing on the introduction of daily mouth care programs for dependent older adults in long-term care has met with limited success. There is a need for greater awareness about the importance of oral health, more education for those providing oral care, and organizational structures that provide policy and administrative support for daily mouth care. The purpose of this paper is to describe the establishment of an oral care action plan for long-term care using an interdisciplinary collaborative approach. Methods. Elements of a program planning cycle that includes assessment, planning, implementation, and evaluation guided this work and are described in this paper. Findings associated with assessment and planning are detailed. Assessment involved exploration of internal and external factors influencing oral care in long-term care and included document review, focus groups and one-on-one interviews with end-users. The planning phase brought care providers, stakeholders, and researchers together to design a set of actions to integrate oral care into the organizational policy and practice of the research settings. Findings. The establishment of a meaningful and productive collaboration was beneficial for developing realistic goals, understanding context and institutional culture, creating actions suitable and applicable for end-users, and laying a foundation for broader networking with relevant stakeholders and health policy makers.

Moving research knowledge into dental hygiene practice.

Dental hygiene, as an emerging profession, needs to increase the number of intervention studies that identify improvements in oral health outcomes for clients. Historically, dental hygiene studies have typically been atheoretical, but the use of theoretical frameworks to guide these studies will increase their meaningfulness. Rogers' theory of diffusion of innovations has been used to study research utilization across many disciplines, and may offer insights to the study of research use in dental hygiene. Research use is an important component of evidence-based practice (EBP), and diffusion of research knowledge is an important process in implementing EBP. The purpose of this paper is to use diffusion of innovations theory to examine knowledge movement in dental hygiene, specifically through the example of the preventive practice of oral cancer screening by dental hygienists, considered as an innovation. Diffusion is considered to be the process by which an innovation moves through communication channels over time among a social network. We suggest diffusion theory holds promise for the study of knowledge movement in dental hygiene, but there are limitations including access to and understanding research studies as innovations. Nevertheless, using a theoretical framework such as Rogers' diffusion of innovations will strengthen the quality of intervention research in dental hygiene, and subsequently, health outcomes for clients.
