Xerostomic medications and oral health: the Veterans Dental Study (part I)

Objectives: To quantify the adverse effects of the number of xerostomic medications on dental caries, oral mucosa, andperiodontal disease. Design: Secondary analysis of across‐sectional study of the Veterans Dental Study. Setting: Four New England area VA outpatient clinics. Subjects: The sample consists of 345 male veterans participating in The Veteran's Dental Study who also had pharmacy records. Main outcome measures: Oral health data included total surfaces of coronal caries, a modification of the root caries index, mean oral mucosa scores, and Community Periodontal Index of Treatment Need (CPITN). Oral health parameters were measured and recorded in clinical dental examinations. Exposures: Intake of xerostomic medications 14‐385 days prior to the dental examination. Statistical Analyses: The relationships between exposure and outcome were analyzed via linear and logistic regression methods adjusting for possible confounding factors such as disease burden index, alcohol consumption, dental care, and smoking status. Results: Veterans who were taking at least one xerostomic medication were almost three times more likely to have mean mucosa scores in the worst 25 percentile than veterans taking no xerostomic medications, OR= 2.63 (confidence interval [CI] 1.34,5.16, p=0.03) after adjusting for age, number of teeth, disease burden index, income, smoking and alcohol use. Participants who were taking at least one xerostomic medication experienced higher but non‐significant increases in coronal (OR =1.21; CI. 0.66, 2.25) and root caries (OR =1.10 CI. 0.54, 2.24) measured by numbers of total decayed surfaces. Conclusion: There were significant deleterious effects of xerostomic medications on oral mucosa. However, xerostomic medications do not appear to increase coronal caries, or periodontal index measured by CPITN among ambulatory, community dwelling participants who were able to perform routine preventive oral care.     

Predicting the Risk of Suicide by Analyzing the Text of Clinical Notes

We developed linguistics-driven prediction models to estimate the risk of suicide. These models were generated from unstructured clinical notes taken from a national sample of U.S. Veterans Administration (VA) medical records. We created three matched cohorts: veterans who committed suicide, veterans who used mental health services and did not commit suicide, and veterans who did not use mental health services and did not commit suicide during the observation period (n = 70 in each group). From the clinical notes, we generated datasets of single keywords and multi-word phrases, and constructed prediction models using a machine-learning algorithm based on a genetic programming framework. The resulting inference accuracy was consistently 65% or more. Our data therefore suggests that computerized text analytics can be applied to unstructured medical records to estimate the risk of suicide. The resulting system could allow clinicians to potentially screen seemingly healthy patients at the primary care level, and to continuously evaluate the suicide risk among psychiatric patients.     

Oral disease experience of older adults seeking oral health services

doi:10.1111/j.1741‐2358.2009.00311.x
Oral disease experience of older adults seeking oral health services Objective: The objective of this investigation was to describe the dental disease (dental caries and alveolar bone loss) experience in a sample of community‐dwelling older adults who regularly utilize dental services in New York City. Background: Public financing for dental care directed at older adults in the United States is minimal. Improved preventive methods, primarily the use of fluorides, have resulted in declines in tooth loss, and concomitant increase in risk for dental diseases among older adults. While the oral disease burden in institutionalized elderly and those unable to access services is well‐documented, the dental care needs of older adults who access dental services are not well documented. Materials and Methods: Radiographic and record review were used to determine prevalence of dental caries, alveolar bone loss, frequency of service utilization, and medical status in this cross‐sectional investigation of a sample of older adults (N = 200) using dental services at Columbia University College of Dental Medicine. Results: Only 9% of the sample was completely edentulous, the mean DMFT was 19.9 and mean alveolar bone loss was 3.6 mm. Missing and Decayed Teeth accounted for 57.8% and 6.5% of the total caries burden respectively. Missing Teeth and alveolar bone loss increased with increasing age, but there was no increase in Decayed Teeth. Conclusions: While access to and utilization of dental services may result in improved tooth retention, older adults who use dental services continue to have dental care needs, especially periodontal care needs.     

Factors influencing older people's self reported use of dental services in the UK

Objectives: This study was designed to determine the use of dental services and factors associated with their use among the United Kingdoms' older population. Design: A national study involving 1,116 older people (aged 60 or older). Setting: Home Interview s were undertaken exploring the time and reason for last dental visit. In addition, socio-demographic characteristics and proxy oral health measures (self-reported number of teeth and edentulous status) of the respondents were collected. Results: Forty seven percent (528) claimed they visited the dentist within the past year, 10% (116) claimed that the reason for their last visit was because of a dental emergency, 43% (484) were classified as “regular attenders” - having attended the dentist within the past year for a non dental emergency. Bivariate analysis identified that regular dental attendance was associated with age (P<0.01), social class (P<0.01), income level (P<0.01), educational attainment (P<0.01), self-reported number of teeth possessed (P<0.01) and edentulous status (P<0.01). In regression analysis, self reported edentulous status and number of teeth possessed emerged as the most important factors in determining service utilisation. Possessing a full denture was associated with a 6-fold decrease, having accounted for other factors, in the likelihood of attending the dentist within the past year for a non dental-emergency (OR=0.15, CI 0.10,0.21). Conclusion: Less than half of the sample population were “regular dental attenders”, their attendance was associated with a number of socio-demographic and oral health factors. In particular, edentulous state was a major factor associated with their use of services.     

Model program for screening oral cancers in the Roma population

Oral cancer has been identified as a significant public health threat. It is reported that about 3,800 new cases of oral cancer are diagnosed in Hungary each year with approximately 1,700 associated deaths. Oral cancer is the 6th most common cancer in men. Most oral cancers are preventable; 75% of oral cancers are related to tobacco use, alcohol use, or use of both substances together. While there is insufficient evidence to support or refute the use of visual examination as a method of screening for oral cancer in the general population, screening in high-risk populations is highly recommended. It was presumed that high-risk behavior including tobacco and alcohol use is one of the characteristics of Roma people. The main aim of the study was to elaborate a screening model program for the Roma population to determine risk factors of oral cancer and establish early diagnosis hence to reduce morbidity and mortality. In the program we planned to survey the risk factors in the target population, establish the diagnosis of oral cancer and/or pre-cancer and direct the patients to health care facilities. First we determined the target population in four Hungarian towns with the help of Roma social workers and local public health officers. We assembled a questionnaire on risk factors. Training for Roma social workers and screening personnel was also accomplished. Screening for oral precancerous lesions and cancer and survey the risk factors in the target population were performed at the same time. Patients screened to be positive were referred to specialists. Altogether 1,146 persons, 656 male and 490 female (age 20-77 years, mean 40 years), participated in the screening; 84% of them reported on some kind of complaints. We have got valid data on risk factors in connection with oral cancer. More than fifty percent of participants did not clean their teeth regularly, 75% were smokers, while 45% drunk alcohol regularly. 1,6% of screened participants had oral lesions that did not require referral to a specialist, while 2.3% of the screened subjects had referable oral mucosal lesions including leukoplakia. The overwhelming majority (93%) of participants screened to be positive did not see dentist regularly. As a conclusion, we elaborated a screening model program, which is applicable for disadvantaged (e.g. Roma) population to determine risk factors of oral cancer and establish early diagnosis hence to reduce morbidity and mortality. We surveyed the risk factors in the target population, established the diagnosis of oral cancer and/or pre-cancer lesions and directed the patients to care facilities. We also assisted them to get appropriate long-term care and follow-up. The importance of screening activities targeted on high-risk population was underlined.     

Oral Health and Treatment Needs of Patients in Two Communal Nursing Homes

The aim of this study was to describe the oral status of patients in two communal nursing homes and to assess the need of those patients for dental treatment. The study was based on a sample that included all patients in the nursing homes of two typical Finnish rural communes. Data were collected for the 132 patients who were examined by a dentist in the nursing homes. As background data for the study we used patient records and interviews. Fifty percent of the patients had no teeth. Among the totally edentulous, every second man and every fourth woman either did not have or did not use dentures. Only half of the patients could be classified as eligible for dental treatment. The main treatment need was prosthetic care treatment. The total estimated number of visits needed per patient was 2.4. The total cost of this treatment series was estimated to be 71 US$/patient. Based on this evaluative study, the dental treatment for nursing home patients could easily be organized by using one dental unit for three weeks.     

Obesity and Receipt of Clinical Preventive Services in Veterans

Although obese individuals utilize health care at higher rates than their normal weight counterparts, they may be less likely to receive certain preventive services. We conducted a retrospective cohort study of veterans with visits to 136 national Veterans Affairs (VA) outpatient clinics in the United States in the year 2000. The cohort included 1,699,219 patients: 94% men, 48% white, and 76% overweight or obese. Overweight and obese patients had higher adjusted odds of receiving each of the targeted clinical preventive services as recommended over 5 years compared with normal weight patients. The odds for receiving vaccinations increased linearly with BMI category: influenza (men: odds ratio (OR) = 1.13 for overweight to OR = 1.42 for obese class 3; women: OR = 1.15 for overweight to OR = 1.61 for obese class 3) and pneumococcus (men: OR = 1.02 for overweight to OR = 1.15 for obese class 3; women: OR = 1.08 for overweight to OR = 1.28 for obese class 3). The odds for receiving the cancer screening services typically peaked in the mild‐moderately obese categories. The highest OR for prostate cancer screening was in obese class 2 (OR = 1.29); for colorectal cancer, obese class 1 (men: OR = 1.15; women OR = 1.10); for breast cancer screening, obese class 2 (OR = 1.19); and for cervical cancer screening, obese class 2 (OR = 1.06). In a large national sample, obese patients received preventive services at higher, not lower, rates than their normal weight peers. This may be due to the VA health service coverage and performance directives, a more homogeneous patient demographic profile, and/or unmeasured factors related to service receipt.     

The hierarchy of approaches to tobacco control

Tobacco represents the single most preventable cause of disease and death in the world today. Of 260 million male deaths in the developed world between 1950 and 2000, it is estimated that 50 million will be due to smoking. In the oral and craniofacial region tobacco use has been associated with the occurrence of cleft palate, periodontal disease and tooth loss, and a variety of soft tissue lesions including oral cancer. For example, smoking is estimated to account for 92% of cancers of the lip, oral cavity and pharynx. Few studies have examined relative efficiency of the many different approaches to tobacco control but, in general, legislative approaches such as increasing tobacco taxes and prohibiting advertising are most effective and those based on printed educational materials and cessation groups, the least effective. In all cases, advice or intervention by health care professionals ranked among the most effective non-legislative approaches to control. A very wide range of professionally-based interventions have been described, including pharmacologic interventions, behavioral approaches and group counseling. The dental profession has a unique opportunity to influence tobacco use by their patients. Its use is almost always immediately evident to the dentist or dental assistant in terms of odor, staining, poor oral hygiene or obvious oral disease. There is also a tendency for the length of personal contact with the dentist to be greater than with a physician. Guidelines are now available that provide the dental professional with advice on the best approaches to tobacco control with their patients.     

Utilization of dental health services by community-dwelling older adults in Japan who attended a weekly educational programme

Objectives: The purpose of this study was to describe dental health services utilization and identify factors which influenced a group of independently living elderly persons in an urban area of Japan. Subjects: The study sample consisted of 2,990 participants, 83% of the total sample of the Senior Citizen's College, who were 60 years and over. Measurements: Their dental utilization and satisfaction with dental treatment were measured by a questionnaire from 1993 to 1998 Results: The mean age of the subjects was 66.5 years and 52% were male. Sixty percent of the subjects had visited a dentist within the previous year, and 33% of them had received a regular oral health check‐up. The majority of the subjects (63%) were satisfied with their dental treatment. A multiple stepwise logistic regression analysis showed that dental services utilization had a significant positive association with presence of teeth (p<0.001), being male (p<0.01) and satisfaction with financial status (p<0.05). A regular oral health check‐ups had a significant association with presence of teeth (p<0.001), satisfaction with financial status (p<0.05) and aging (p=0.001). Conclusions: Dental health services utilization was related to the presence of teeth and financial status, rather than age or medical conditions, among independently living elderly persons in an urban area of Japan.     

Weight management for veterans: examining change in weight before and after MOVE!

In the year 2000, 31% of women and 40% of men receiving outpatient care at Veteran Affairs (VA) medical facilities were overweight (BMI ≥25 and <30 kg/m(2)); 37.4% of women and 32.9% of men were obese (BMI ≥30 kg/m(2)). The purpose of the present study was to assess treatment effects of MOVE! Weight Management Program for Veterans by comparing the trajectory of change in weight postintervention (3, 6, and 12 months postenrollment) to a preintervention period (1, 3, and 5 years before enrollment). The sample consisted of 862 veterans participating in MOVE! at the Miami VA. All veterans participated in a 2-h Self-Management Support (SMS) session, which involved completion of a self-assessment questionnaire and a nutrition education group session. After completing SMS, veterans had the option of continuing with Supportive Group Sessions (SGS), which included 10-weekly group sessions led by a multidisciplinary team. Veterans served as their own controls in the analyses. Veterans gained 2 kg/year before enrolling in MOVE!. There were similar increases in weight across sex, racial/ethnic groups, and treatment condition. Weight for participants in SMS stabilized after enrollment whereas participants in SGS had an average weight loss of 1.6 kg/year. The preintervention slope for weight was significantly different from the postintervention slope, suggesting treatment effect. Findings from this study support the need for a lifestyle modification program such as MOVE! in primary care settings to assist overweight and obese patients in managing their weight.     

Oral health care for frail elderly people: actual state and opinions of dentists towards a well-organised community approach

Objective: This study was undertaken to provide an analysis of the actual oral heath care for frail elderly people living in different settings and to explore opinions of dentists towards new concepts in developing a community approach. Method: Data were collected from a sample of 101 dentists (15%) in the county of Antwerp using a self‐administered 30‐item questionnaire including questions about age, gender, education, organisational aspects of dental surgery, questions concerning dentists’ own contribution to oral healthcare services for frail elderly people and statements concerning opinions and attitude toward the organisation of oral health care for frail elderly people. At the same time, qualitative data were collected from focus group sessions with all participating dentists. Non‐parametric analysis was used to explore possible relationships between opinion and possible explanatory variables. Results: Half of the dentists offered dental services to residential or nursing homes (mean number of treatments a year: 5.4) and at home (mean number of treatments a year: 2.4). Prosthetic treatments such as relieving denture pressure points, repairing, rebasing and making new dentures were carried out in 77.4% and 76.7% of the cases in residential or nursing homes and at home respectively. Extractions were carried out in 16% and 18.6% of the cases in both living situations respectively. The main reasons for dentists refusing domiciliary oral health care were the absence of dental equipment (63%), lack of time (19%), with 11% convincing the patients to be treated in their dental surgery. Analysis showed different opinions of dentists depending on age, gender and university of education; however, statistically significant differences were only found by age. Conclusion: The older the dentist, the greater the tendency to refuse domiciliary oral healthcare services. The younger dentists were reluctant to cooperate in the provision of oral health care in a structured community approach.     

Perspectives on providing good access to dental services for elderly people: patient selection,dentists’ responsibility and budget management

doi: 10.1111/j.1741‐2358.2012.00646.x Perspectives on providing good access to dental services for elderly people: patient selection, dentists’ responsibility and budget management Objectives: To suggest a model for organizing and financing dental services for elderly people so that they have good access to services. Background: There are few studies on how dental services for elderly people should be organized and financed. This is surprising if we take into consideration the fact that the proportion of elderly people is growing faster than any other group in the population, and that elderly people have more dental diseases and poorer access to dental services than the rest of the adult population. In several countries, dental services are characterized by private providers who often operate in a market with competition and free price‐setting. Private dentists have no community responsibility, and they are free to choose which patients they treat. Material and methods: Literature review and critical reasoning. Results: In order to avoid patient selection, a patient list system for elderly people is recommended, with per capita remuneration for the patients that the dentist is given responsibility for. The patient list system means that the dentist assumes responsibility for a well‐defined list of elderly people. Conclusion: Our model will lead to greater security in the dentist/patient relationship, and patients with great treatment needs will be ensured access to dental services.     

Oral complaints and utilization of dental services in relation to general health factors in a 88-year-old Swedish population*

The aim of this study was to describe dental state, oral health problems, self-assessed ability to perform oral hygiene and utilization of oral health services in a sample of 88-year-old people (n=374) and to relate these variables to functional ability, subjective health and drug consumption. The intention was also to Identify barriers to utilization of dental care in non-institutionalized elderly people. The results of interviews showed that 46% of the subjects were dentate. Oral complaints were reported by 24% of the home living individuals. Poor health, medication and feelings of loneliness were factors associated with oral discomfort. Difficulties in performing oral hygiene activities were reported by 10% of the subjects and were correlated with functional impairments and feelings of loneliness. Utilization of dental services was correlated with dental state; 72% of the dentate and 8% of the edentulous subjects made regular dental visits. The main reason for not visiting a dentist was “no perceived need”. Independent of dental state, some factors were significantly correlated to low demand for dental services; these included feelings of loneliness, functional impairments and low school education.     

Veterans’ Perspectives on Interventions to Improve Retention in HIV Care

Poor retention in HIV medical care is associated with increased mortality among patients with HIV/AIDS. Developing new interventions to improve retention in HIV primary care is needed. The Department of Veteran Affairs (VA) is the largest single provider of HIV care in the US. We sought to understand what veterans would want in an intervention to improve retention in VA HIV care. We conducted 18 one-on-one interviews and 15 outpatient focus groups with 46 patients living with HIV infection from the Michael E. DeBakey VAMC (MEDVAMC). Analysis identified three focus areas for improving retention in care: developing an HIV friendly clinic environment, providing mental health and substance use treatment concurrent with HIV care and encouraging peer support from other Veterans with HIV.     

Self-perceived oral health and access to care in diabetic and non-diabetic women: A qualitative study

BackgroundAccess to dental care is of growing importance to individuals with chronic illnesses and policymakers alike.ObjectivesTo explore personal views of diabetic and non-diabetic women regarding their oral health and access to dental care.MethodsA qualitative study was performed involving 6 diabetic and 6 non-diabetic female hospital attendees. A thematic framework approach was used to analyze the interviews.ResultsResponses yield three emerging central themes: oral health impact, self-maintained oral health and dental service delivery and costs. Personal views varied particularly in oral health self-perception and visiting the dentist. Certain drawbacks shadowed the quality of care in governmental and private sectors. Response variations were observed among diabetics and non-diabetics.ConclusionWithin the study limits, female hospital attendees had variable responses on how they looked upon their oral health. A variation in oral hygiene practices and visiting the dentist was observed. Participants believed that governmental and private clinics offered high quality care, with high treatment costs in private clinics and long waiting times in the public service being the main drawbacks. Practical Significance: Importance of supporting patients, educating practitioners and alarming policymakers about the impact of oral health problems and access to dental care.     

Barriers to provision of dental care in long-term care facilities: the confrontation with ageing and death

Objective: The aim of the study was to reveal barriers to providing dental care for residents in long‐term care (LTC) facilities. Design: Participants were selected randomly from the dentist register in Berlin and Saxony, Germany. The sample consisted of 60 self‐employed and 60 employed dentists, a further 60 dentists worked in their own dental practice but also part‐time in an LTC facility. In semi‐structured interviews a questionnaire with 36 statements concerning working conditions, administration and cost, insecurity concerning treatment decisions as well as confrontation with ageing and death was employed. Subsequently, the study participants were asked to rank the four dimensions concerning their impact on the decision against providing dental care in an LTC facility. Results: The random sample was representative in age and gender for the dental register in Berlin and Saxony. Fifty‐six per cent of the participants (63% of the men and 51% of the women; 52% of the self‐employed, 60% of the employed and 56% of the consultant dentists) indicated unfavourable working conditions as biggest obstacle in providing dental care in an LTC‐facility. Thirty‐two per cent of participants rated administration and cost, 7% the insecurity in treatment decisions as major hindrance. Only 5% of the participants rated the confrontation with age and death as substantial barrier. There were no age and gender differences. Dentists in Berlin seemed more concerned about administration and cost of a consultancy activity and less secure in their therapy decisions than the colleagues from Saxony (p < 0.001). Dentists who work partly in LTC facilities were the least concerned about the confrontation with ageing and death (not significant), employed dentist showed the least secure in their treatment decisions (p > 0.001). Conclusion: It can be concluded that the awareness of infra‐structural and financial aspects in providing dental care in LTC facilities should be raised with health politicians and that these aspects should be considered when inaugurating or re‐structuring the consultancy services to LTC facilities. Further it would be desirable to establish more postgraduate training programmes to increase clinical and ethical competence in the area of gerodontology.     

Dental health of elderly confederate veterans: evidence from the Texas State Cemetery

Analysis of the skeletal remains of 50 Confederate veterans provided a unique opportunity to explore the dental health of a geriatric sample. These men, who died between 1907-1932, had an average age at death of 76.7 years. Ninety percent were institutionalized at the Confederate Home for Men (Austin, TX) prior to their deaths. This elderly sample was assessed in terms of caries, antemortem tooth loss (AMTL), abscesses, and linear enamel hypoplasias. On a per tooth basis, the AMTL rate was 57.2%. Of 39 dentate men, 33 (84.6%) had dental caries, and 24.4% (121 of 496) of teeth were carious. Ten (25.0%) of the dentate men had hypoplastic teeth. At least one abscess was seen in 14 (28%) of 50 individuals. Results from this geriatric institutionalized sample are compared to contemporaneous historical samples. Disparities in dental health among these groups may be due to differences in average age at death, and these comparisons allow a better understanding of dental changes that occur with age. The sample is also compared to modern elderly samples: modern groups have higher caries rates, possibly because they retained more teeth. This finding may be due in part to diets in the United States becoming increasingly cariogenic over time. In addition, dental care has moved from the reactive practices seen in the nineteenth and early twentieth centuries (such as tooth extractions) to modern proactive solutions dedicated to preserving and restoring teeth (such as tooth brushing, fluoride treatments, and dental fillings).     

Oral health and dental care facilities in Maltese residential homes

Objectives: To establish oral health care practices, including the use of dental services, in the residential homes of Malta and Gozo by assessing the knowledge of home managers and assistance of care staff regarding residents’ oral health and hygiene; and evaluating the residents’ demand for dental treatment and residential home managers response to this demand. Subjects: A total population sample of licensed residential homes (38) in Malta and Gozo was used comprising all home managers in government (seven), church (20), and privately run (11) residential homes. Method: A 19‐question questionnaire was designed, piloted and sent to the home managers requesting them to report on the dental care provision for their elderly residents. The questionnaire was distributed by post, along with a reply‐paid envelope and an explanatory letter. A response deadline of 1 month was included. Results: An 87% response rate was achieved. Whilst the majority of home managers (64%) were aware of domiciliary dental services, there was no code of care practice for oral health. Routine dental check‐ups were not organised for residents of most homes. Although home staffs were generally given information about residents’ oral health and hygiene, the majority did not assist residents with oral hygiene. Home managers identified the following barriers to the use of dental services by residents: cost, communication problems with dental staff, journey to place of treatment, waiting time at the dental clinic, access to premises/clinic, lack of information on oral health and dental service availability, no one to accompany the person to the clinic, and health problems such as mobility, poor eyesight, hearing impairment and mental health status. Conclusion: Although most home managers appreciate the importance of oral health care for their residents, the residents still face many barriers to maintaining adequate oral health care and accessing dental services.     

Prevalence of dental myths,oral hygiene methods and tobacco habits in an ageing North Indian rural population

doi: 10.1111/j.1741‐2358.2010.00395.x
Prevalence of dental myths, oral hygiene methods and tobacco habits in an ageing North Indian rural population Background and objectives: Though increased emphasis is being given to expanding dental care facilities and awareness in Indian villages, the target population is unfortunately less literate and financially‐equipped compared to their urban counterparts. This study attempted to evaluate dental myths, oral hygiene methods and beliefs, and tobacco habits present in a rural ageing population. Material and methods: The study area consisted of a group of 10 villages, situated in the district of Lucknow, Uttar Pradesh, India. The sample comprised 681 people aged 50 years or above. The subjects were questioned about dental myths, tobacco habits and oral hygiene methods and then divided into groups on the basis of age, gender, and educational status. Mean values, standard deviation, chi‐square test, t‐test and p values were used to obtain inter‐group comparisons. Results: Forty percent of the subjects considered oral hygiene unnecessary, with 61% relying on simple mouth rinsing for maintaining oral hygiene, 48% either smoked and chewed tobacco or both and 81% had one or more dental myth. Conclusion: The results showed that the rural ageing population is deprived and a targeted programme to spread scientific dental practices to them is necessary.
