The aim of the present study was to describe the Norwegian adult population according to: 1. number of teeth present, 2. demand and utilization of dental services, 3. travel time from home to the dentist, 4. dental health behaviour, 5. fear for dental treatment. The analyses were performed on a set of national data collected in 1989, which was representative of the non-institutionalized Norwegian population 20 years and above. The sample size was 1260 individuals. About 75% of the people had 20 teeth or more present. Nine percent were edentulous. Seventy-seven percent who had demanded dental services during the last year. The average expenditure for dental treatment for those who had demanded the services during the last year was NOK 826. Fifty-three percent travelled 15 minutes or less from home to the dentist. Eighteen percent travelled 30 minutes or more. Almost everybody with their own teeth present brushed their teeth regularly once a day. Thirty-three percent of all dentate people used woodsticks regularly once a day, while 20% used toothfloss regularly. Seventy-five percent had no to mild fear of the dentist, while 7% had a strong fear. Fear of the dentist was higher among women than among men. Fear of the dentist decreased by increasing age. Few people, less than 4%, had cancelled a dental appointment because of dental anxiety. There has been an improvement in dental health and dental health behaviour in Norway during the 1970's and 1980's. These improvements are discussed with special attention paid to the findings from the present study.
Utilization of dental services by 30 diabetic and 30 nondiabetic subjects was assessed by longitudinal monitoring over a period of 3 years. All subjects were examined clinically three times, and their treatment consisted mainly of cariologic and periodontal treatment. The treatment was delivered by a dentist and an expanded-duty dental hygienist. The study groups were similar with regard to the total number of dental visits needed. However, the treatment of diabetic subjects was more demanding in that more dentist's workload was needed for the diabetic group. They also missed more appointments without cancellation and therefore more office time had to be reserved for them.
The aim of this study was to compare treatment provided to adult heavy and low users of dental services in the Finnish Public Dental Service (PDS) and to analyse changes in patients' oral health status. We assigned all adults who attended the PDS in Espoo in 2004 to a group of heavy users (n = 3,173) if they had made six or more dental visits and to a comparison group of low users (n = 22,820), if they had made three or fewer dental visits. Data were obtained from the patient register of the PDS. A sample of 320 patients was randomly selected from each group. Baseline information (year 2004) on age, sex, number and types of visits, oral health status and treatment provided was collected from treatment records. Both groups were followed-up for five years. Restorative treatment measures dominated the heavy and low users'treatments; 88.8% of heavy users and 79.6% low users had received restorations during the five-year period. Fixed prosthetic treatments were provided to just 2% of the heavy users and 0.8% of the low users. Emergency visits were more common for heavy users (74.8%) than for low users (21.6%) (p
The study deals with the frequency of using dental services and continuity of visting the same dentist by adults in Finland during the 5 years up to 1981. A representative sample of 17-65 year old Finnish adults was interviewed by telephone or when this was not possible, personally. The data were collected by the Central Statistical Office of Finland in autumn 1981. Twenty-two per cent of the subjects had not visited a dentist during the past 5 years. One-third had had more than three treatment courses during the same period. The number of treatment periods increased with higher educational and professional status. Half of the subjects who had had more than one treatment period had continued to attend the same dentist during different treatment periods. Young persons had changed dentist more often than older ones. The most common reason for changing dentist was change of residence. Nine percent did not wish to continue treatment with the same dentist. Income, age, profession and region of living accounted for 10% of the number of changes of dentist.
A study was conducted among 367 persons aged 60 and over in order to determine the type and severity of digestive and nutritional problems experienced by edentulous elderly not wearing functional dentures. This article summarizes the information collected through an interview. The data describes the prosthetic status and experience of the elderly, their use of dental services and their methods of hygiene. In addition, information is provided on the level of satisfaction relative to their dentures and the need for repair or replacement of the latter.
A population-based survey was conducted in the two northernmost provinces of Finland to describe the incidence of tongue cancer as well as patient and tumour characteristics in cases diagnosed between 1974 and 1994. A total of 105 new patients with cancer of the oral tongue were included in the 21-year study period. The age-standardised incidence (per 100,000 years) of the carcinoma in men increased from 0.6 in the first 7-year period (1974-1980) to 1.0 in the last period (1988-1994). The incidences in women were 0.7 to 1.4, respectively. The average patient profile remained much the same through the years. The median duration of symptoms also remained the same over the 2 decades, as did the median size and location of the tumour at diagnosis. In conclusion, the incidence of carcinoma of the tongue about doubled in both the male and the female population from 1974 to 1994. However, the patient and tumour characteristics remained about the same, the tumours being relatively large at the time of diagnosis in spite of well-developed community health and dental care.
The purpose of the present paper was to establish and evaluate a causal model on the use of dental services in Norwegian old-age pensioners living at home. Data were derived from the Health Survey of 1975. The independent variables sex, age, education and dental status were dichotomized and arranged in this assumed temporal sequence. The dependent variable was also dichotomized into use versus non-use of dental services last year. The analysis started with the bivariate percentage table for sex and use, and then proceeded by adding one by one of the independent variables in the order of their time sequence. In this way the statistical relationship between an independent and the dependent variable was decomposed into direct, indirect and spurious effects. Dental status was the most influential determinant of use of services, having the greatest direct effect (0.40) and mediating indirect effect of the prior variables. Education came second with a direct effect of 0.18 and an indirect effect (0.11) by affecting dental status. There were only negligible differences in use rates between the age groups (less than 75 / greater than or equal to 75 years of age) when the other variables were held constant (0.05, P greater than 0.05). The greater part of the direct effect of sex (0.11) was limited to dentate persons aged 65-74 with low education. Both age and sex affected use of services indirectly through dental status (0.09 and --0.04, respectively).
With the aim of gauging utilization rates of dental services, a series of cross-sectional studies were performed in 1973, 1975 adnd 1977. Cluster samples of 1,600 individuals covering the Norwegian population aged 15 and above were interviewed by trained interviewers using standardized questions. The percentage of respondents who reported having seen a dentist within the last 12 months increased from 58 to 64. The receipt of tooth fillings was the predominant course of treatment and was reported by 55% of the interviewees. The percentage reporting preventive services increased from 15 to 26% at the expense of those reporting "blood and vulcanite" denistry. Fifty-two percent, increasing to 53% of the interviewers, claimed to have seen a dentist on a regular basis during the last 5 years. However, this proportion was conceivably overreported. Control questions indicated that 40-45% should be considered regular treatment attenders. Change is apparently taking place in the treatment pattern. The proportion of regular treatment attenders seems to increase by 0.5-1% per year. The treatment profile is also shifting: extractions and denture services are diminishing, preventive services are gaining, while restorative dentistry stands still - for the time being.
