A comparison of tooth retention and replacement across 15 countries in the over-50s

Tooth Loss and Systemic Diseases in the Slovenian Elderly Population: A Cross-Sectional Study of the Associaton Between Oral and Systemic Health

Introduction

This study aimed to assess the prevalence of edentulism and tooth loss in the Slovenian elderly population, along with the associated risk factors, and investigate the association between systemic and oral health.

Methods

The study included 445 individuals aged 65 or older (average age: 79.7±8.9 years). Data on preserved teeth, dental history, chronic diseases, and medications were collected through clinical examinations. Height and weight were recorded in order to calculate body mass index (BMI), and the education level was also collected. Chronic systemic diseases and medications were categorized. Statistical analysis was conducted using linear regression and nonparametric tests.

Results

Participants had an average of 4.7±7.7 teeth, with no significant gender differences. Higher age (β=-0.185, p<0.001) and lower education level (p<0.001) were associated with fewer teeth, while higher BMI showed no correlation (β=-0.085, p=0.325). Diabetes mellitus (p=0.031), cardiovascular diseases (p=0.025), and thyroid diseases (p=0.043) were inversely related to retained teeth. This inverse relationship also applied to individuals who recovered from malignancies, not including head and neck malignancies (p=0.019). No significant relationship was found between osteoporosis and the number of teeth (p=0.573). Notably, antidiabetic drug use was inversely related to the number of teeth (p=0.004), while analgesics showed a positive relationship (p=0.022).

Conclusions

This study highlights the association between specific sociodemographic factors, chronic diseases, and retained teeth among elderly individuals in Slovenia. High edentulism rates among the elderly emphasize the need for enhanced preventive measures and risk factor management, particularly for high-risk groups like the elderly.

Self-perceived oral health and orofacial appearance in older adults - an 18-year follow-up study in Karlskrona, Sweden

OBJECTIVES

To analyze whether self-perceived oral health and orofacial appearance change with increasing age.

METHODS

This longitudinal study is based on data from a questionnaire used in the Swedish National Study of Aging and Care. The sample comprises 160 participants 60 years of age at baseline 2001-2003. The same participants were re-examined at 66-, 72-, and 78 years of age. To analyze whether perceptions of oral health and orofacial appearance changed with increasing age, Cochran's Q test was conducted. Statistical significance was considered at p  ≤  0.05, and the calculated value Q must be equal to or greater than the critical chi-square value (Q ≥ 7.82). Significance values have been adjusted for the Bonferroni correction for multiple tests.

RESULTS

Self-perceived mouth dryness, both day (Q = 7.94) and night (Q = 23.41), increased over the 18-year follow-up. When divided by gender, significant differences were only seen for mouth dryness at nighttime. A decrease in sensitive teeth was perceived with increasing age, and an increase in self-perceived satisfaction with dental appearance, and a decrease in self-perceived problems with dental gaps between the ages of 60 and 78. These changes were, however, not statistically significant. Men experienced a higher proportion of discomfort with discolored teeth at age 78 than at 60 (Q = 9.09).

CONCLUSIONS

Self-perceived oral health and orofacial appearance were relatively stable, with few changes over an 18-year follow-up.

'Whose role is it anyway?' Experiences of community nurses in the delivery and support of oral health care for older people living at home: a grounded theory study

BACKGROUND

Older people who receive care at home are likely to require support with oral health care. Community nurses, who are also referred to as district or home care nurses, have an important role with this population. This is because they are the healthcare professionals who are most likely to encounter this population, who may also not be receiving regular dental care or oral health promotion. However, few studies have explored community nursing experiences in the delivery and support of oral healthcare for older people living at home.

METHODS

A grounded theory approach was used to explore experiences of community nurses in the delivery and support of oral health care for older people living at home. Fifteen practising community nurses from the United Kingdom participated in one-to-one semi-structed interviews from May 2021 to December 2021. These interviews were audio-recorded, transcribed verbatim and analysed using constant comparative analysis. Ethical approval was obtained for this study prior to data collection.

RESULTS

Four categories emerged from the data to support development of the core phenomena. These four categories were: (1) Education, in relation to what community nurses knew about oral health, (2) Practice, with regards to how community nurses delivered oral health care to older people in their own home, (3) Confidence, with consideration to the extent to which this supported or impeded community nurses in providing oral healthcare to older people and (4) Motivation, in terms of the extent to which community nurses thought they could or should influence future practice improvement in the area. The core category was (C) Uncertainty as it was both present and central across all four categories and related to community nursing understanding about their specific role, and the role of other professionals, with reference to oral health of their patients.

CONCLUSIONS

This study reveals community nurses' uncertainty in providing oral healthcare to older adults at home. Emphasising comprehensive and continuous oral health education can boost nurses' confidence in patient support. Interprofessional collaboration and clear role definitions with oral health professionals are crucial for improving oral health outcomes in this vulnerable population.

Effect of Korean Dental Hygienists' Experiences Related to the Elderly on Their Perception of Human Rights Violations of the Elderly: A Cross-Sectional Study

Background: Korean society has become an elderly society at an unprecedented rate, and the associated social and economic problems are very serious. Maintaining a healthy oral condition is important for older people’s well-being and quality of life, and is essential for healthy ageing. Therefore, the purpose of this study was to investigate the effect of dental hygienists’ experiences related to the elderly on their perception of human rights violations toward the elderly. Methods: This study was conducted through an IRB review at Silla University in Korea (No. 1041449-202012-HR-001). For about a month after 1 February 2021, the survey questionnaire was distributed to dental hygienists living in South Korea, and 153 people who completed and sent back the questionnaires were selected as the final subjects. The items on the questionnaire consisted of perception of human rights violations for the elderly and experiences related to the elderly. A polyserial correlation analysis was performed to confirm the relevance of each factor, and a multiple regression analysis was performed to identify the factors of elderly-related experiences that affect the perception of human rights violations against the elderly. Results: All three experiences related to the elderly (the experience of receiving education related to the elderly, the experience of volunteer work related to the elderly, and the experience of being interested in issues related to the elderly) were highly related to the perception of violations of financial human rights of the elderly (p < 0.01). In addition, the experience of education related to the elderly showed a high perception of psychological violations of the human rights of the elderly (R = 0.405, p < 0.01), and the experience of volunteer activities related to the elderly showed a high perception of neglectful violations of human rights of the elderly (R = 0.277, p < 0.01). Conclusions: In this study, it was confirmed that there is a relationship between dental hygienists’ experiences related to the elderly and their perception of human rights violations in the elderly. Therefore, dental hygienists should do their best to manage the elderly’s oral health by raising awareness of the human rights violations against the elderly through the elderly professional course based on their experience with the elderly.

Impaired Oral Health in Older Orthopaedic In-Care Patients: The Influence of Medication and Morbidity

Introduction

Fall-related injuries are prevalent in older patients and often lead to increased morbidity, medication, and impaired functions. We studied older trauma patients with the aim to describe their oral health in comparison to morbidity and medication.

Material and Methods

The study included 198 patients, ≥65 years, admitted with an orthopedic trauma. Oral examinations included number of natural teeth, dental implants, missing, decayed and restored teeth, root remnants, and pocket depth. Data on comorbidities and medication were assembled. Statistical analyses were carried out with logistic regression models, adjusted for age, gender, comorbidity, and polypharmacy.

Results

Overall, 198 patients participated, 71% women, mean age 81 years (±7.9), 85% resided in their own homes, 86% had hip fractures. Chronic diseases and drug use were present in 98.9%, a mean of 6.67 in Charlson comorbidity index (CCI), 40% heart diseases, 17% diabetes, and 14% dementia. Ninety-one percent were dentate (181), mean number of teeth 19.2 (±6.5), 24% had decayed teeth, 97% filled teeth, 44% <20 teeth, and 26% oral dryness. DFT (decayed, filled teeth) over mean were identified in patients with diabetes (p=0.037), COPD (p=0.048), polypharmacy (p=0.011), diuretics (p=0.007), and inhalation drugs (p=0.032). Use of ≥2 strong anticholinergic drugs were observed in patients with <20 teeth and DFT over mean (p=0.004, 0.003). Adjusted for age, gender, CCI, and polypharmacy.

Conclusion

The study showed that impaired oral health was prevalent in older trauma patients and that negative effects on oral health were significantly associated with chronic diseases and drug use. The results emphasize the importance of identifying orthogeriatric patients with oral health problems and to stress the necessity to uphold good oral care during a period when functional decline can be expected.

Mortality in Edentulous Patients: A Registry-Based Cohort Study in Sweden Comparing 8463 Patients Treated with Removable Dentures or Implant-Supported Dental Prostheses

Objectives

The purpose of this study was to investigate if edentulism is associated with all-cause mortality. The aims were to analyze the association between age, socioeconomic factors, and mortality in edentulous patients treated with either removable dentures or implant-supported prostheses.

Methods

All patients who became edentulous according to the Swedish Social Insurance Agency (SSIA) between 2009 and 2013 (N  = 8463) were analyzed regarding prosthetic treatment, age, gender, and socioeconomic status. The patients were divided into two groups, depending on whether they were treated with dental implants (implant group; IG) or with conventional removable dentures (denture group; DG). Data on mortality for all included individuals were obtained from the Swedish National Cause of Death Register and compared to a reference population. Cumulative survival rates were calculated, and a multivariable regression analysis for the included variables was performed.

Results

Between 2009 and 2018, 2192 of the patients (25.9%) were treated with implant-supported dental prostheses (IG) and 6271 patients (74.1%) were treated with removable dentures without support of dental implants (DG). Altogether 2526 patients (30%) died until December 31, 2019, and the overall mortality was significantly higher for the DG compared to the IG during follow-up (p < 0.001). Younger edentulous patients (≤59 years) presented a higher mortality than the reference population, while implant patients over 79 years of age demonstrated a lower mortality. The final results from the multivariable logistic analysis showed that lower equalized disposable income (EDI) and the choice of conventional removable dentures are the most important factors for increased patient mortality (p < 0.001).

Conclusions

Edentulous patients have an overall higher mortality compared to a reference population. Low socioeconomic status increases all-cause mortality. Individuals treated with dental implants show statistically significant lower 10-year mortality compared to patients treated with conventional removable dentures, regardless of socioeconomic status.

Trends in dentate status and preventive dental visits of the adult population in Denmark over 30 years (1987-2017)

This study analyzed the trend in self-reported dentate status over 30 years (1987-2017) among Danish adults, the self-reported frequencies of preventive dental visits undertaken annually during the period 1987-2013, and the self-reported use of the 2016 recall scheme for preventive dental check-ups. The impact of social determinants (education, employment, civil status, and ethnic background) on these dental outcome variables in 2017 was explored. Questionnaire data were obtained from the Danish Health and Morbidity Surveys conducted from 1987-2017, and they were analyzed by tri-variate frequency distributions and multivariate analyses. The prevalence of complete tooth loss was 17.7% in 1987 but 3.4% in 2017. The frequency of adults having 20 or more teeth grew markedly from 1987 (65.9%) to 2017 (85.1%). Educational inequality in dentate status persisted over the period. The frequency of preventive dental visits at least annually increased from 1987 to 2013, although visits were less frequent for young people. In 2017, preventive dental check-ups were reported in intervals: less than 12 months (56.4%), 12-18 months (18.9%), 19-24 months (4.8%), and more than 24 months (5.2%). In 2017, dentate status and preventive dental check-ups varied profoundly by social determinants. In conclusion, social policies should be implemented to tackle the persistent inequities in dentate status and public health policies should target Universal Health Coverage.

Older people's experiences of oral health and assisted daily oral care in short-term facilities

Background

Older people’s oral health has improved, and many retain their natural teeth throughout their life. However, their daily oral care can be more difficult because of compromised general health and the reduced capacity for self-care that often comes with old age. More knowledge is needed about how older people view their oral health and oral care. The aim of this study was to describe how older people in short-term care experience their oral health and daily oral care.

Method

A descriptive, qualitative study was performed through interviews with 14 older people (74–95 years) recruited from short-term care units in two Swedish regions. Data were analysed using inductive content analysis.

Results

The findings are described in one main category, three categories and nine sub-categories. The main category was Adapting to a changed oral condition while striving to retain independence. The first category, Wanting to manage daily oral care independently, contained three subcategories: Having always brushed my teeth without help, Being satisfied with my mouth and teeth, and Having to accept help if necessary. The second category, Acceptance of changes in oral condition, had three subcategories: Difficulty in chewing and swallowing, Difficulty with tooth brushing, and Not considering a dentist visit to be worth the cost. The third category, Barriers to receiving assistance from staff, had three subcategories: Staff lacking the time to help, Not wanting to be a burden, and Lack of confidence in staff’s knowledge.

Conclusions

The participants were generally satisfied with their oral health despite an expressed need for dental treatment. Daily oral care was something they wanted to manage themselves, and they had a strong desire to stay independent for as long as possible. Closer collaboration between dental and health care staff is necessary in order to implement clinical practice guidelines for oral health care and increase nursing staff’s attention towards older peoples’ oral health.

Patient factors related to early implant failures in the edentulous jaw: A large retrospective case-control study

BACKGROUND

Dental implants provide anchorage for dental prostheses to restore functions for individuals with edentulous jaws. During the healing phase, proper osseointegration is required to prevent early implant failure. More knowledge is needed regarding factors related to early failure of dental implants.

PURPOSE

The aim of the present study was to identify possible risk factors for early implant failure, with respect to anamnestic and clinical parameters.

MATERIALS AND METHODS

All patients with edentulous jaws with early implant failure (n = 408) from one referral clinic were compared with a matched control group (n = 408) with no implant failure. Early implant failure was identified during the first year of prosthetic function. Matching was performed on age, gender, year of surgery, type of jaw, and type of implant surface. In addition, data on anamnestic and clinical parameters were collected. The data were analyzed with a multivariable logistic regression model using early implant failure as the binary outcome.

RESULTS

Five anamnestic factors were statistically significant with respect to higher probability for early implant failure: systemic disease, allergies in general, food allergies, smoking, and intake of analgesic medication. Four clinical conditions (i.e., implants in the opposing jaw, low primary stability, reduced bone volume, and healing complications) were also related to higher probability for early implant failure.

CONCLUSIONS

This study identified nine factors associated with early implant failure, several related to patient's general health. Further investigations are needed to fully understand the causality between the obtained variables and early implant failure.

Impacts of Tooth Loss on OHRQoL in an Adult Population in Cape Town, South Africa

(1) Background: Tooth loss is an important component of the global burden of oral disease, greatly reducing the quality of life of those affected. Tooth loss can also affect diet and subsequent incidences of lifestyle diseases, such as hypertension and metabolic syndromes. This study aimed to evaluate the oral health-related quality of life (OHRQoL) score using the oral impacts on daily performance (OIDP) index in relation to tooth loss patterns among adults. (2) Methods: From 2014 to 2016, a cross-sectional study was conducted on adults living in Bellville South, Cape Town, South Africa. The OHRQoL measure was used to evaluate the impact of tooth loss. (3) Results: A total of 1615 participants were included, and 143 (8.85%) had at least one impact (OIDP > 0). Males were less likely to experience at least one impact compared to the females, OR=0.6, 95% C.I.: 0.385 to 0.942, p = 0.026. Those participants who did not seek dental help due to financial constraints were 6.54 (4.49 to 9.54) times more likely to experience at least one impact, p < 0.001. (4) Conclusions: Tooth loss did not impact the OHRQoL of these subjects. There was no difference in the reported odds for participants experiencing at least one oral impact with the loss of their four anterior teeth, the loss of their posterior occlusal pairs, or the loss of their other teeth.

Factors Associated with Extraction following Root Canal Filling in Adults

Essentially, root fillings are performed to preserve natural teeth. Over time, however, some root-filled teeth will inevitably be extracted. The aim of this historical prospective cohort study in the adult Swedish population was to identify factors associated with extractions within 5 y of registration of a root filling. The cohort consisted of all those whose root fillings had been reported to the tax-funded Swedish Social Insurance Agency (SSIA) in 2009. Demographic data on the individuals registered with a root filling (sex, age, country of birth, disposable income, educational level, and marital status) were received from Statistics Sweden or the SSIA. Dental care setting, tooth type, and any registration of subsequent restorations within 6 mo were received from the SSIA. Multivariable regression analysis was used, and P < 0.05 was considered statistically significant. In total, 216,764 individuals had been registered with at least 1 root filling. Individuals (n = 824) without complete data were excluded from the analyses. After 5 y, 9.3% of the root-filled teeth had been registered as extracted. Logistic regression analysis found significant associations for all variables except country of birth, disposable income, and educational level. The highest odds ratios for extractions were associated with the type of restoration: teeth with no registration of any restoration and teeth with a direct restoration combined with a post were 3 times more likely to undergo extraction than teeth restored with an indirect restoration combined with a post and core. Overall, high odds ratios for extractions were associated with any type of composite restoration, including composite fillings and crowns combined with or without any post. In summary, after root filling in the Swedish adult population, several individual- and tooth-specific variables were associated with extraction. The reasons for the extractions remain to be studied further.

5-year randomized multicenter clinical trial on single dental implants placed in the midline of the edentulous mandible

OBJECTIVES

This multicenter randomized controlled clinical trial was conducted to investigate whether the loading protocol of single dental implants placed in the midline of edentulous mandibles will influence the implant survival or prosthetic maintenance.

MATERIALS AND METHODS

In total, 158 patients were randomly assigned either to the immediate loading group (n = 81) or to the delayed loading group (n = 77). All implants were loaded with an overdenture retained by a ball attachment.

RESULTS

After 5 years, 102 patients attended the follow-up investigation. Immediately loaded single implants in the midline of the edentulous mandible revealed a statistically significant lower survival rate than implants loaded conventionally over an observation period of 5 years. In the immediate loading group, 9 implants failed within the first three months of implant loading. No further implant loss was recorded for this group. Two implants failed in the delayed loading group, whereas one implant had to be removed during second-stage surgery and the second five years after implant loading. Non-inferiority of the survival rate of the midline implant of the immediate loading group, compared with the delayed loading group, could not be shown (p = .79, CI immediate loading: 74.9%; 100.0%, CI delayed loading: 73.0%; 100.0%). The observed difference in implant survival between the two treatment groups over time was statistically significant.

CONCLUSIONS

The results of the present study indicate that immediate loading of a single mandibular implant in the edentulous mandible should be considered only in exceptional cases.

Root-retained overdentures: Survival of abutment teeth with precision attachments on root caps depends on overdenture design

BACKGROUND

Root-retained overdentures (OD) are one treatment option for partially edentulous patients. However, the available evidence regarding factors influencing abutment survival in root-retained ODs is limited.

PURPOSE

This retrospective study included clinical examinations and evaluated the survival rate of roots restored with precision attachments soldered to post-and-core (gold cap) retained ODs, analysed with respect to various patient- and prosthesis-related factors.

METHODS

Patients receiving at least one OD with gold caps in the past were invited for comprehensive clinical examinations. The primary outcome parameter was the abutment survival rate over the observation period (2002-2016). Possible contributing factors (eg closed vs open OD design) were analysed. Analyses included Kaplan-Meier estimators, Cox regressions and hazard ratios (HR).

RESULTS

114 patients with 128 ODs originally retained by 280 abutments, with a cumulative total exposure time of 2035.4 years, were examined. Twenty-seven abutment teeth (9.6%) were lost after a mean observation period of 7.9 ± 3.4 years. Significant factors associated with abutment loss were a closed, compared to an open OD design (HR 8.38 (95% CI 1.11-63.59), P = .040), which was independent of the number of abutments per OD. Furthermore, the loss rate was higher when the denture was not worn day-and-night (HR 3.52 (95% CI 1.32-9.40), P = .012). Oral hygiene behaviour was associated with higher HRs.

CONCLUSIONS

ODs remain a viable treatment option for patients with few teeth remaining in the dental arch. It is advisable to choose an open design for the OD, irrespective of the number of abutment teeth. Furthermore, gold cap-retained ODs should not be removed overnight.

Association of oral health with body weight: a prospective study in community-dwelling older adults

BACKGROUND

To prevent involuntary weight loss in older people, the knowledge about factors affecting body weight (BW) is essential. Therefore, we aimed to investigate the longitudinal associations of multiple oral health aspects with BW in community-dwelling older adults.

METHODS

This analysis is based on prospective data with a 10-year follow-up of 657 Dutch community-dwelling older adults (age 66.4 ± 5.8 years, 54% female) from the Longitudinal Aging Study Amsterdam. Participants' characteristics, BW, and 12 oral health variables (teeth, dentures, nine oral problems, self-rated oral health) were assessed in 2005/07 and 2015/16. The association between oral health and BW was analyzed by mixed models and adjusted for demographic, socio-economic, smoking, health, and functional aspects considering data of both assessments.

RESULTS

Mean BW was 79.1 ± 13.3 kg at baseline (B) and 77.6 ± 13.8 kg at follow-up (FU). At baseline, 29.6% of the participants reported being edentulous (FU:34.4%) and 55.8% to wear dentures (FU:62.3%). Dental pain while chewing was the oral problem with the lowest (B:5.2%, FU:6.6%) and xerostomia with the highest prevalence at both examinations (B:24.3%, FU:30.0%). Most participants rated their oral status as healthy (B:65.2%, FU:66.9%). Neither edentulism and denture use nor oral problems showed a longitudinal association with BW. In contrast, self-rated oral health was associated with BW (b = 0.724, SE = 0.296, p = 0.015) after adjusting for multiple confounders.

CONCLUSIONS

In community-dwelling older adults self-rated oral health may indicate changes in body weight in the long term. Therefore, this simple measure could serve to identify a risk for weight loss and to initiate oral interventions in clinical practice.

Factors Related to the Number of Existing Teeth among Korean Adults Aged 55-79 Years

This study aimed to determine the association between the number of existing teeth (NET) and socioeconomic status (SES), oral health-related behaviours, and metabolic syndrome in Korean adults aged 55-79 years. The study included 3255 adults who underwent oral health examinations and answered questionnaires regarding SES, oral health-related behaviours, and metabolic diseases in the Sixth Korea National Health and Nutrition Examination Survey (2013-2015). The dependent variable was the binary status based on the median NET in each age group. The independent variables were based on SES, oral health-related behaviours, and the presence of metabolic syndrome. The study findings showed that the factors associated with the NET were sex, household income, education level, region of residence, daily toothbrushing frequency, dental visit within 1 year, smoking, and metabolic syndrome. NET was lower in males (adjusted OR: 0.74), in low household income group (adjusted OR: 0.77), in primary school graduates (adjusted OR: 0.53), in rural residents (adjusted OR: 0.78), and in medicaid beneficiaries (adjusted OR: 0.78). The interventions aimed at preserving existing teeth in elderly population should consider their SES, oral health-related behaviours, and metabolic syndrome and overhauling current oral healthcare system and redefining the roles of oral health professionals.

Geospatial distribution of periodontists and US adults with severe periodontitis

BACKGROUND

In this study, the authors report on the geospatial distributions of periodontists and adults with severe periodontitis in the United States.

METHODS

The authors used geospatial analysis to describe the distribution of periodontists and adults, periodontists vis-à-vis estimated density of adults with severe periodontitis, and their ratios to adults with severe periodontitis. The authors identified locations of 5,415 practicing periodontists through the 2014 National Provider Identifier Registry, linked them with the weighted census number of adults, and estimated the number of adults within a series of circular distance zones.

RESULTS

Approximately 60% of adults 30 through 79 years lived within 5 miles of a periodontist, 73% within 10 miles, 85% within 20 miles, and 97% within 50 miles. Proximity to a periodontist varied widely. In urban areas, 95% of adults resided within 10 miles of a periodontist and 100% within 20 miles. Only 24% of adults in rural areas lived within 10 miles of a periodontist. Most periodontists (96.1%) practiced in urban areas, clustering along the eastern and western coasts and in the Midwest, 3.1% in urban clusters elsewhere, and 0.8% in rural areas. Ratios of fewer than 8,000 adults with periodontitis to 1 or more periodontists within 10 miles were clustered mostly in the Northeast, central East Coast, Florida, West Coast, Arizona, and Midwest.

CONCLUSIONS

In this study, the authors identified wide variations in geographic proximity to a practicing periodontist for adults with severe periodontitis.

PRACTICAL IMPLICATIONS

Dental practitioners may provide preventive care and counseling for periodontitis and referrals for specialty care. Geographic proximity to specialized periodontal care may vary widely by locality.

Oral health of community-dwelling older Australian men: the Concord Health and Ageing in Men Project (CHAMP)

BACKGROUND

The Concord Health and Ageing in Men Project (CHAMP) is a cohort study of the health of a representative sample of Australian men aged 70 years and older. The aim of this report is to describe the oral health of these men.

METHODS

Oral health was assessed when the men were all aged 78 years or older. Two calibrated examiners conducted a standardized intraoral assessment. Descriptive data were analysed by statistical association tests. Participants were excluded from the collection of some periodontal assessments if they had a medical contraindication.

RESULTS

Dental assessments of 614 participants revealed 90 (14.6%) were edentate. Men had a mean of 13.8 missing teeth and 10.3 filled teeth. Dentate participants had a mean of 1.1 teeth with active coronal decay. Those in the low-income group had a higher rate of decayed teeth and lower rate of filled teeth. Thirty-four participants (5.5%) had one or more dental implants, and 66.3% relied on substitute natural teeth for functional occlusion. Of those with full periodontal assessments; 90.9% had sites with pocket depths of 3 mm or more, 96.6% had sites with CAL of 5 mm or more, and 79.7% had three or more sites with GI scores of 2 or more.

CONCLUSIONS

There was a high prevalence of periodontal diseases and restorative burden of dentitions, which suggests that greater attention needs to be given to prevention and health maintenance in older Australian men.

Higher education in Gerodontology in European Universities

Background

The rapid aging of the European population and the subsequent increase in the oral care needs in older adults necessitates adequate training of dental professionals in Gerodontology (Geriatric Dentistry). This study was designed to investigate the current status of Gerodontology teaching amongst European dental schools at the undergraduate, postgraduate and continuing education levels.

Methods

An electronic questionnaire was developed by a panel of experts and emailed to the Deans or other contact persons of 216 dental schools across 39 European countries. The questionnaire recorded activity levels, contents and methodology of Gerodontology teaching as part of dental education programs. Repeated e-mail reminders and telephone calls were used to encourage non-responders to complete the questionnaire.

Results

A total of 123 responses from 29 countries were received (response rate: 56.9%). Gerodontology was taught in 86.2% of schools at the undergraduate level, in 30.9% at the postgraduate level and in 30.1% at the continuing education level. A total of 43.9% of the responding schools had a dedicated Gerodontology program director. Gerodontology was taught as an independent subject in 37.4% of the respondent schools. Medical problems in old age, salivary impairment and prosthodontic management were the most commonly covered topics in Gerodontology teaching. Clinical teaching took place in 64.2% of the respondent schools, with 26.8% offering clinical training in outreach facilities.

Conclusions

The vast majority of European dental schools currently teach Gerodontology at the undergraduate level. More training opportunities in oral care of frail elders should be offered, and more emphasis should be placed on interdisciplinary and interprofessional training, educational collaborations, and the use of modern technologies. Dedicated postgraduate Gerodontology courses need to be developed to create a significant number of specialized dentists and trained academics.
