Abstract
OBJECTIVES This register-based study on public sector patients aged 60 years and over assessed annual age-specific volume of and reasons for tooth extractions as well as changes in these across the period 2007-2015. BACKGROUND Alongside the rapidly ageing population, the demand for public oral healthcare services is growing. Damaged teeth may induce a long-lasting inflammation burden in old age. MATERIALS AND METHODS Data used the electronic documentation of oral healthcare procedures recorded according to healthcare regulation. The study population consisted of all patients over 60 years of age (n = 216 059) who were treated 2007-2015 in public oral health care available to all citizens of Helsinki, Finland. Data for the 9-year time series included reasons for tooth extractions and were aggregated by patient age into 5-year groups. Statistical analyses included rates and proportions, mean values, correlation coefficients and linear regression modelling. RESULTS Extraction patients (n = 48 623) were more likely in the older age groups: 21.8% in the age group 60-64 and 27.5% in the age group 90+. Mean number of tooth extractions among all patients was 0.4 per patient and 1.7 per extraction patient. Among all tooth extractions (n = 82 677), main reasons were caries 29.5%, apical periodontitis 19.4%, tooth remnant 19.4% and periodontitis 18.0%. Tooth remnant predominated as extraction reason in the oldest age groups, while apical periodontitis displayed an upward trend by calendar year. CONCLUSION Tooth extractions attributable to caries were common in all old-age groups, tooth remnant extractions were most common in older age groups, and apical periodontitis abounded as extraction reason during 2007-2015.

The Effect of Surface Processing on the Shear Strength of Cobalt-Chromium Dental Alloy and Ceramics. MATERIALS 2022; 15:ma15092987. [PMID: 35591320 PMCID: PMC9103724 DOI: 10.3390/ma15092987] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/09/2022] [Revised: 04/12/2022] [Accepted: 04/14/2022] [Indexed: 02/05/2023]
Abstract
Porcelain fused to metal is widespread dental prosthetic restoration. The survival rate of metal-ceramic restorations depends not only on the qualifications of dentists, dental technicians but also on the adhesive strength of ceramics to a metal frame. The goal of the research is to determine the optimal parameters of the surface machining of the metal frame to increase the adhesion of metal to ceramics. Adhesion of cobalt-chromium alloy and ceramics was investigated. A profilometer and a scanning electron microscope were used to analyze the morphology. To estimate the adhesion the shear strength was measured by the method based on ASTM D1002-10. A method of surface microrelief formation of metal samples by plasma-electrolyte treatment has been developed. Regimes for plasma-electrolyte surface treatment were investigated according to current-voltage characteristics and a surface roughness parameter. The samples were subjected to different surface machining techniques such as polishing, milling, sandblasting (so-called traditional methods), and plasma-electrolyte processing. Morphology of the surface for all samples was studied and the difference in microrelief was shown. The roughness and adhesive strength were measured for samples either. As a result, the mode for plasma- electrolytic surface treatment under which the adhesive strength was increased up to 183% (compared with the traditional methods) was found.

Abstract
OBJECTIVES To assess the oral health of older people who visit the community dental practice from both the dentists' and the patients' perspective. MATERIALS AND METHODS In this exploratory cross-sectional study the oral health of Dutch community dwelling older people was assessed. A representative sample of general dental practitioners was asked to randomly and prospectively select one older patient and describe this patient using a specially-developed registration form; in addition the patient was requested to complete a questionnaire. The oral health of older people was described from the perspective of the dentists and the perspective of the older people themselves based on the definition of oral health from the World Dental Federation (FDI]. Relations between oral health of older people and dentist and older patient characteristics were analysed using Spearman's rank correlation coefficient (rho) and an ordinal regression model. RESULTS In total, 923 dentists were asked to participate in the study; data was available for 39.4% dentist-patient pairs. Dentists assessed the oral health of older patients as good or acceptable in 51.4% of the cases while this was the case in 76.2% of older patients themselves. The assessment of the dentist gets more negative with high treatment intensity and with older patients having certain diseases and more medication, while the assessment is more positive for older patients who visit the dentist on a regular basis. Older people's assessment of their oral health gets more negative by being female and with high treatment intensity, having certain diseases and higher use of medication. CONCLUSIONS AND CLINICAL RELEVANCE Chronically illness as expressed by the number of diseases and the use of medication, seems to be a risk factor for poor oral health. Older patients themselves assess their oral health differently, mostly more positive, than their dentist.

Abstract
BACKGROUND There are many determinants that can affect inequality in oral and dental health. This study is aimed to explore the main determinants of inequality in both utilization and provision of dental services in Organization for Economic Co-operation and Development (OECD) countries. METHODS Four databases including PubMed, ISI WOS, Scopus, and ProQuest were searched up to 8 Aug 2020, applying the relevant keywords. Thematic analysis was used for synthesizing and extracting data. Trend analysis was applied to determine the trends of the inequality determinants. RESULTS Thematic analysis led to 6 main themes, 13 sub-themes, and 53 sub-sub-themes. The main themes represent the main inequality determinants for both utilization and provision of dental services. The streamgraph illustrated that fewer studies have been conducted on social and cultural determinants, and for almost all determinants the trend of published articles has been increasing since 2007, with the exception of health policies. CONCLUSIONS Inequality in the utilization and provision of dental services is addressed by various factors including individual, social, cultural and economic determinants, health policies, and availability of services. The first four determinants are related to utilization and the last two are related to the provision of services. All these aspects must be considered to reduce inequality in dental services.

Abstract
The diversity bonus theorem developed by Scott Page postulates that in specific environments, diversity is an absolute necessity to creating the most successful team. The theorem dispels the myth that institutions must choose between diversity and excellence. Within oral and maxillofacial surgery, this bonus is captured through expanded access to care, more equitable and relevant research, and attracting the best and brightest to the specialty. To capture the bonus, oral and maxillofacial surgery must invest in policy changes to admissions and hiring practices, and offer training in communication, cultural competency, and implicit bias.

Abstract
BACKGROUND Research into oral health care for older people has shown that dental care in general decreases with increasing age and frailty and, therefore, oral health care provision may be complex. The aim of this study is to identify the oral health care dentists provide to community-dwelling older people and which barriers they experience in doing this. METHODS In this cross-sectional study, a representative sample of dentists in the Netherlands was asked to prospectively select one older patient and describe this patient using a specially developed registration form; the patient was requested to fill out a questionnaire. The relationship between experienced barriers in providing oral health care to older patients and characteristics of the dentists and the patients was studied by means univariate and multivariate logistic regression analysis. RESULTS In total, 923 dentists were asked to participate in the study. Data were available for 39.4% dentist-patient pairs. In most cases (87.4%), oral health care was focussed on conservation of the dentition. In all, 14.0% of the dentists experienced barriers in providing oral health care for older people. Some patient factors increase the risk of experiencing barriers, eg, the more difficult behaviour of older patients and the greater disease burden. CONCLUSIONS Oral health care was mostly focussed on conservation of the dentition, and dentists especially experience barriers in oral health provision to older patients if they are already frail.

Abstract
BACKGROUND Older adults are keeping their natural teeth longer, spurring calls for dental coverage under Medicare. Although Medicare dental coverage would benefit all older adults, the poorest among them are already eligible for dental benefits through Medicaid. The authors examine the association between states' Medicaid adult dental benefits and dental care use and tooth loss among low-income older adults. METHODS Using the Behavioral Risk Factor Surveillance System data from 2014, 2016, and 2018, the authors examined adults 65 years or older. The outcomes examined included annual dental visit and partial and complete tooth loss. Poisson regressions were used to obtain risk ratios after adjusting for covariates. RESULTS States' Medicaid adult dental benefits were significantly associated with dental care use, with low-income older adults in states with no coverage having the lowest probability of visiting a dentist (risk ratio [RR], 0.83; 95% CI, 0.74 to 0.94), followed by emergency-only coverage (RR, 0.91; 95% CI, 0.84 to 0.98) and limited benefits (RR, 0.91; 95% CI, 0.85 to 0.98) relative to states with extensive benefits. There were no significant differences in either partial or complete tooth loss. CONCLUSIONS States' Medicaid adult dental benefits are significantly associated with dental visits among low-income seniors. Providing comprehensive dental benefits under Medicaid can improve access to dental care among low-income older adults. PRACTICAL IMPLICATIONS As the older adult patient population grows, the poorest older adults may face barriers to dental care in the absence of dental coverage. Dental professionals must engage in advocating for comprehensive dental coverage, especially for vulnerable populations.

Abstract
The relationship between oral health status and bone mineral density has been poorly elucidated. We conducted a cross-sectional study to examine the relationship between oral health status and bone mineral density with data from healthy community-dwelling elderly individuals in Ohnan-cho, Shimane Japan who were recruited in 2019 for the Shimane Center for Community-Based Health Research and Education (CoHRE) study. The study included 702 participants (306 men and 396 women). The median age, bone mineral density, and number of remaining teeth were 69.0 years, 86.2%, and 26.0, respectively. The two groups (Low teeth group and High teeth group) showed significant differences in age, hemoglobin A1c (HbA1c) level, and masticatory function in men (p < 0.05). In women, age, number of untreated teeth, and masticatory function were significantly different (p < 0.05). The odds ratio of propensity score analysis for the association between the number of remaining teeth and bone mineral density was 27.7 (95% confidence interval: 1.86–414.9, p < 0.05). The number of remaining teeth could be associated with bone mineral density in the healthy elderly women, and no significant association was observed in men. Number of remaining teeth and bone mineral density may be interrelated, and oral care by dentists/dental hygienists may play an important role in maintaining bone mineral density in elderly women.

Abstract
OBJECTIVES We estimated the association between the use of preventive dental care and medical use and expense for older persons over a 2-year period to determine if a Medicare dental benefit for routine care could result in potential cost savings in Medicare. METHODS We relied on 2008-2014 Medical Expenditure Panel Survey data to estimate separate logistic and lognormal ordinary least squares regressions to analyze the influence of year 1 preventive dental care on either year 1 or year 2 use and expenses for total health care, office-based care, outpatient care, inpatient stays, emergency department visits, and prescription drugs. RESULTS Our findings provide evidence over a 2-year period that a Medicare dental benefit for routine care could produce an increase in office-based visits and expense. We also found that older persons currently using routine dental care have healthier lifestyles and greater access to care and use of preventive medical care than current nonusers. CONCLUSION Our results affirm the need for a longer-term study to provide any conclusive evidence as to the ultimate impact of a Medicare dental benefit on other health care use and expenses.
