Influences of some background factors on the subjective need for dental implants in a Swedish population.

On the basis of a questionnaire sent to 3000 randomly sampled individuals aged 45-69 years and living in an average Swedish county (response rate, 79.4%), the influences of some demographic socioeconomic, and attitude variables on the subjective need for treatment with dental implants were studied in stepwise logistic regression models. The overall influence of these background factors was rather limited. Instead, the most important single factor seemed to be dental status. For the subjects wearing removable partial dentures, low education was significantly related to a low subjective need for implant treatment. For the totally edentulous group of subjects, low income was most significantly associated with a low subjective need for implant therapy.

Factors affecting attitudes toward dental appearance and dental function in a Swedish population aged 45-69 years.

A questionnaire study was carried out on a random sample of 3,000 adults aged 45-69 years, living in Orebro county, Sweden. The response rate was 79.4 per cent. The purpose of this study was to develop measurements of attitudes toward dental function and dental appearance, and to investigate the relative importance of socio-economic factors to these attitudes. In factor analysis, two unidimensional variables explaining almost 54 per cent of the variance were developed, measuring the attitude to the importance of dental appearance and dental function. The variables were only moderately correlated. Bivariate and multivariate logistic regression models were constructed, where low education was related to high importance of dental appearance, and low socio-economic status and its interaction with education were related to high importance of dental function. Both models had low predictive values and no significant relationships were found with age, gender, marital status, place of residence, use of dental care, or to satisfaction with teeth or received care. It is concluded that it should be possible to influence attitudes to dental conditions irrespective of demographic or socio-economic factors.

Correction of self-assessment of dental conditions.

A correction matrix for self-assessed data on dental conditions was developed. 100 subjects, who were randomly selected among 2383 respondents to a questionnaire, were clinically examined. The dental conditions, determined clinically and through self-assessment, were recoded to seven dental categories, and the agreement between the two methods of reporting were investigated. For persons with prosthodontic work and/or edentulous persons the self-assessment was valid, whereas people with remaining teeth overreported their dental conditions through self-assessment. The overreporting did not depend on gender, but was dependent on age, which again was related to dental status. The overreporting was most marked for persons having one to two single teeth or several single teeth missing and not replaced.

Explanatory models for total edentulousness, presence of removable dentures, and complete dental arches in a Swedish population.

On the basis of data from a questionnaire study of 3000 inhabitants of Orebro County, Sweden, aged 45-69 years, the relative importance of various socioeconomic factors for dental conditions were analyzed in stepwise logistic regression models. Two different patterns were found: one in relation to the best dental condition (complete dental arches), another in relation to the poorest conditions (total edentulousness and presence of removable dentures). Next to age, education and income showed the highest predictive values in relation to the presence of removable dentures and total edentulousness. Place of residence and gender seemed to be of less importance than earlier. In relation to complete dental arches, there were lower values for most variables. One of only four significant variables was the attitude variable 'importance of good dental appearance'. The results may indicate the development of a new pattern of influences on dental conditions, mainly based on education and attitudes.

Factors determining satisfaction with dental care.

The objective of the present study was to study satisfaction with previous dental care in a Swedish population aged 45-69 years. The relationship between a number of factors and satisfaction with care was studied, and differences between people attending private and public dental clinics were examined. The data were collected by an anonymous questionnaire. A multivariate analysis showed that reported satisfaction with previous dental care depended primarily on three factors; treatment by the dentist of choice, chewing ability and contentment with their own dental conditions.

Some factors influencing the quantity of prosthodontic treatment performed by general practitioners in public dental service.

For general dentists in public dental service, Orebro county, the numbers of artificial crowns, pontics, RPD:s and CRD:s produced in 1989 were studied in relation to some background factors. The dentist-related factors were: gender, time in profession, working time per week, and place of graduation. Factors related to dental clinics were: location of the clinic, general prosthodontic activity at the clinic. Multiple regression analyses were used. Two different patterns were found; one for fixed prosthodontics, another for removable prosthodontics. Prosthodontic activity at the clinic, the male sex, and (inversely) time in profession were significantly associated with high production of artificial crowns and pontics. The regression models for removable prosthodontics showed no significance.

Self-assessment of dental conditions: validity of a questionnaire.

In order to determine the validity of dental data obtained from a questionnaire, 100 subjects randomly selected from 2383 respondents were examined clinically. The quality of dental status was ordered in four groups for the number of missing and replaced teeth and for denture status. For the number of missing and replaced teeth, the observed agreement between the clinical diagnosis and the questionnaire answers was 65% for both the maxilla and the mandible, and the agreement estimated by Kappa was 0.52. However, the disagreement was not randomly distributed, since reporting of better dental status than the actual one was much more common than reporting of poorer status. Regarding denture status, the agreement between self-assessment and clinical diagnosis was good; all removable dentures in situ at the clinical examination were reported by the subjects as some kind of denture, although not always the correct type. The results of the study indicate that the use of self-assessment might be reasonable when measuring denture status, and that self-assessment of the number of missing and replaced teeth is a biased estimate of the clinical diagnosis. Thus appropriate action should be taken when using this type of data.

Dental conditions in a Swedish population aged 45-69 years. A questionnaire study.

A questionnaire study was performed on 3000 randomly sampled individuals aged 45-69 years living in Orebro county, Sweden. The response rate was almost 80%. The purpose was to describe dental conditions in this population, especially differences in dental conditions between various socioeconomic groups. Only 9% of the studied population were totally edentulous, and edentulousness was concentrated to the older age groups. Eighteen per cent of the population had all their teeth remaining. Removable dentures were worn by only 23% of the subjects. The results indicate further improvement of dental conditions in the age group 45-69 years in in Orebro county and presumably in the whole country. The results also indicate an improved gender equality with regard to dental status. On the other hand, socioeconomic inequalities were closely related to variations in dental conditions.

Utilization of dental services in an elderly population.

In 1982-83 the elderly population of Orebro county, Sweden, was studied. Out of 500 randomly sampled individuals, 305 were examined clinically, 158 interviewed by telephone. Both groups were asked about i.a. the length of time since their last dental visit. In the clinical group a treatment need was assessed. Fifty percent of all reported visits to a dentist within the last three years. There were significant differences between age, residence, and especially dental status groups. The figures were slightly higher for the clinically examined group, as compared to the total: Fifty-five percent had visited a dentist within the last three years. However, the differences between the subgroups remained the same. In a multivariate analysis, two variables were significantly related to the utilization of dental services: age, and most significantly dental status. In 1986 a follow-up study was performed on the clinical group. In the years 1983-85, 69% of the subjects had received dental care. There were no differences between age, sex, or residence groups, but there were still a considerable difference between dentulous subjects (84%) and edentulous subjects (43%). The treatment received in 1983-85 was compared to the need registered in 1982-83. Only one variable - total edentulousness - was significantly related to a lower level of treatment received; whereas other variables, e.g. the income variable, were not.

Alveolar bone levels in a geriatric Swedish population.

A random sample of non-institutionalized elderly people in Orebro County, Sweden, has been examined. The present report studies marginal bone levels in this population. Measurements were made on intra-oral radiographs. The marginal bone levels of the teeth were measured in fifths between the apex and a point 1 mm apical to the cemento-enamel junction. More than 87% of the teeth received a bone score 1 or 2, which indicates that more than 60% of the original bone level was remaining. About half of the teeth were given the bone score of 1, i.e., having more than 80% of the original bone level intact. For those subjects receiving regular dental treatment, the average bone level index (mean bone score for the subject) was lower than for the others. The general bone level of a subject is described by a classification which takes into consideration only the best 70% of the teeth. Using these bone level classes, people aged 65-74 years positively differ from older groups. The % of subjects belonging to the better bone level classes increases with increasing number of remaining teeth. In a multiple stepwise regression analysis, the number of teeth is the only predictor having significant correlation to bone level index. A variable such as regular treatment in itself seems to have little influence.

Oral health patterns in a Swedish county population aged 65 and above.

The aims of the study were to survey oral health and related conditions in the population of non-institutionalized elderly people in Orebro County, Sweden, and to analyze the relative importance of certain factors within the oral health pattern. A random sample was taken of 500 non-institutionalized individuals, stratified according to age (65-74/75+) and residence (densely-populated areas/rest of county). Out of these subjects 305 were examined clinically; 158 interviewed by telephone. Totally 46% were edentulous; 35% in age group 65-74, 63% in age group 75+; 36% of the men were edentulous, 53% of the women. The lowest prevalence of edentulousness (9%) was found among married/cohabiting men in group 65-74 years, densely-populated areas. The mean number of remaining teeth in dentulous subjects was 17.1 in group 65-74 densely-populated areas; 10.1 in group 75+ rest of county. Regarding dental status the group 65-74 densely-populated areas consistently showed the best values, the group 75+ rest of county consistently showed the poorest values. Two subgroups diverged from the general pattern: the men in group 65-74 rest of county often showed poorer values than the others in aged 65-74; the men in group 75+ densely-populated areas often showed better values than the others aged 75+. The periodontal conditions were good or fairly good. Only 4% of the teeth had periodontal pockets 6 mm or deeper. Measured radiographically, about half of the teeth had 80% or more of the original bone level intact; 87% of the teeth had 60% or more of the original bone level remaining. Only 28% of the subjects had no periapical destruction. Ten percent of the teeth showed periapical destructions - 27% of root filled teeth; 6% in teeth without root fillings. Eighteen percent of the teeth were root filled - 27% of maxillary teeth, 11% of mandibular teeth. The root fillings were evaluated "not acceptable" in 69% of the teeth. Periapical destructions were more frequent in teeth with "not acceptable" root fillings as compared to those "acceptable" root filled. Socio-economic conditions were highly correlated with a number of dental parameters. In men those who were not married or cohabiting showed the poorest values; in women the differences were smaller but the highest prevalence of edentulousness was found in widows.(ABSTRACT TRUNCATED AT 400 WORDS)

Denture stomatitis in nursing home patients.

All 352 patients in two nursing-homes in Orebro were examined. In one of the homes microbiological tests could be done on the patients with full upper dentures. The samples were taken both from the denture and the oral mucosa. Candida albicans, Yeast, Staph. aureus, B-hemolytic streptococci and Klebsiella/Enterobacter were controlled. In samples from the oral mucosa a correlation was found between stomatitis, Candida albicans and Staph. aureus (P less than 0.01). A weak correlation was also found between stomatitis and Klebsiella/Enterobacter (0.01 less than P less than 0.05). In samples from the dentures there were only a weaker correlation between Stomatitis, Candida albicans and Staph. aureus (0.1 less than P less than 0.05).

Nursing - home patients in Orebro. Oral status and aspects of dental care.

An epidemiological study of oral status in two nursing-homes in Orebro was performed. Totally 352 patients were examined. In one of the nursing-home stomatitis occurred more frequent among younger than older denture wearers greater than 75 years old (P less than 0.05). In the other home there was a correlation between denture hygiene and stomatitis (P less than 0,01). The estimated need of treatment from different types of dental personal was calculated for one of the homes. 17.6% of the patients needed treatment by a dentist. For the other patients the dentist was only necessary for planning and leading treatment performed by other nursing personal.
