- The aim of this study was to compare changes in periodontal status in a Swedish poplation over a period of 20 years. Cross-sectional studies were carried out in Jönköping County in 1973, 1983, and 1993. Individuals were randomly selected from the following age groups: 20, 30, 40, 50, 60, and 70 years. A total of 600 individuals were examined in 1973, 597 in 1983, and 584 in 1993. The number of dentate individuals was 537 in 1973, 550 in 1983, and 552 in 1993. Based on clinical data and full mouth intra-oral radiographs, all individuals were classified into 5 groups according to the severity of the periodontal disease experience. Individuals were classified as having a healthy periodontium (group 1), gingivitis without signs of alveolar bone loss (group 2), moderate alveolar bone loss not exceeding 1/3 of the normal alveolar bone height (group 3), severe alveolar bone loss ranging between 1/3 and 2/3 of the normal alveolar bone height (group 4), or alveolar bone loss exceeding 2/3 of the normal bone height and angular bony defects and/or furcation defects (group 5). During these 20 years, the number of individuals in groups 1 and 2 increased from 49% in 1973 to 60% in 1993. In addition, there was a decrease in the number of individuals in group 3, the group with moderate periodontal bone loss. Groups 4 and 5 comprised 13% of the population and showed no change in general between 1983 and 1993. The individuals comprising these groups in 1993, however, had more teeth than those who comprised these groups in 1983; on the average, the individuals in disease group 4 had 4 more teeth and those in disease group 5, 2 more teeth per subject. In 1973, these 2 groups were considerably smaller, probably because of wider indications for tooth extractions and fewer possibilities for periodontal care which meant that many of these individuals had become edentulous and were not placed in a group. Individuals in groups 3, 4, and 5 were subdivided according to the number of surfaces (%) with gingivitis and periodontal pockets (≥4 mm). In 1993, 20%, 42%, and 67% of the individuals in groups 3, 4, and 5 respectively were classified as diseased and in need of periodontal therapy with >20% bleeding sites and >10% sites with periodontal pockets ≥4 mm. In conclusion, an increase in the number of individuals with no marginal bone loss and a decrease in the number of individuals with moderate alveolar bone loss can be seen. The prevalence of individuals in the severe periodontal disease groups (4, 5) was unchanged during the last 10 years; however, the number of teeth per subject increased.

- The periodontal condition of the inhabitants of Jönköping County, Sweden was followed for 20 years by means of 3 cross-sectional investigations performed in 1973, 1983, and 1993. The study comprised individuals in the age groups 20, 30, 40, 50, 60, and 70 years. The number of dentate individuals was 537 in 1973, 550 in 1983, and 552 in 1993. All individuals participating in the studies were examined clinically and radiographically. They also filled out a questionaire about dental care habits, socio-economic status, and general health. A clear reduction in the plaque score was seen between 1973 and 1983 in all age groups. With one exception, no further significant change in plaque levels was found between 1983 and 1993: the increase in plaque among the 20-year-olds was significant. In 1993 the mean % of surfaces with plaque was between 30% and 40% in all age groups. Gingivitis values corresponded well with the values of dental plaque; the same pattern with a clear reduction in gingivitis score was seen in all age groups between 1973 and 1983, and an increase in the mean frequency of gingival inflammation between 1983 and 1993 was seen in the 20-year age group. 30% of the individuals in this age group had more than 50% gingivitis in 1993 compared with 9% of the individuals in 1983. The 20-year-olds were further analyzed in a linear regression model using gingivitis as a dependent variable against some socio-economic, general health, and dental care variables associated with poor oral hygiene and gingivitis. In 1993, the most important explanatory variable was gender: significantly more males than females had higher gingivitis scores. The second most important explanatory variable was toothbrushing habits. Together they explained 10.9% of the variance. The multivariate analysis did not reveal approximal cleaning habits to be significant, probably due to their strong connection to gender and toothbrushing habits. In the 1983 sample, no significant explanatory variables were found. It was concluded from this data that it is important not only to renew but also to direct preventive guidelines more towards young adults who have no previous extensive experience of oral disease so that they will not be excluded from dental care and their dental health thereby jeopardised. In addition to preventive programmes aimed at the population as a whole, individual programmes based on risk targeting are also necessary to reduce the number of people developing dental disease and to increase the quality of dental care.

- Background: Clinical signs of heart failure such as pulmonary rales and dyspnea, ventricular dysfunction, and ventricular arrhythmia are independent predictors of a poor prognosis after acute myocardial infarction (AMI).Hypothesis: The study aimed to assess the effect of ramipril treatment on mildly depressed left ventricular (LV) systolic function, assessed by atrioventricular (AV) plane displacement in patients with congestive heart failure after AMI.Methods: The study was a substudy in the Acute Infarction Ramipril Efficacy Study, a double-blind, randomized, placebo-controlled trial of ramipril versus placebo in patients with symptoms of heart failure after AMI. In all, 56 patients were included in the main study, 4 refused to participate in the substudy, and 4 were excluded for logistical reasons. Echocardiography was performed at entry and after 6 months. Patients who underwent coronary artery bypass grafting during the follow-up period were excluded.Results: At baseline, the patients had modest LV dysfunction, and mean AV plane displacement of 9.7 mm. During follow-up, AV plane displacement increased in ramipril-treated patients from 9.5 to 10.9 mm (p<0.01). No statistically significant changes were seen in the placebo group.Conclusions: Ramipril improves LV systolic function in patients with clinical signs of heart failure and only modest systolic dysfunction after AMI. Measurement of AV plane displacement is a simple and reproducible method for detection of small changes in systolic function and may be used instead of ejection fraction in patients with poor image quality.

- The aim of this clinical study was to compare the treatment outcome following root surface conditioning using an EDTA gel preparation in conjunction with surgical therapy with that following conventional flap surgery in periodontal intraosseous defects. 36 patients, each of them contributing one intraosseous defect ≥4 mm in depth participated. Defect sites had a probing pocket depth ≥5 mm and bled on probing following hygienic treatment phase. No furcation involvement or endodontic complications were present. In the EDTA group, 18 consecutive patients, defects were treated by root conditioning with EDTA gel for 3 minutes in combination with surgical therapy. In the control group, 18 patients, conventional flap surgery was performed without root conditioning. Chlorhexidine rinsings 0.2% were prescribed following surgery for 2-3 weeks with modified oral hygiene instruction. A strict recall program was implemented including professional prophylaxis and oral hygiene reinforcement every 4-6 weeks until 6-month re-evaluation. Baseline probing pocket depths and defect depths of 7.1±1.3 mm and 6.9±1.6 mm in the EDTA group and 7.6±1.9 mm and 6.6±1.7 mm, respectively, in the control group were measured. 6-month clinical results showed a significant probing attachment level gain of 1.8±1.5 mm and 1.0±1.7 mm in the EDTA and control groups respectively. A probing bone gain of 1.0±1.3 mm in the EDTA group was measured with a non-significant gain of 0.4±1.2 mm in the control group. Radiographic analysis confirmed these results. There were no statistically significant differences in treatment outcome between the group treated by root conditioning in combination with flap surgery and conventional flap surgery alone.

Tidskriftsartikel (refereegranskat)abstract
- In this study, potential risk factors for severe periodontal disease were identified in a cross-sectional sample from the county of Jönköping, Sweden. 547 adults 20-70 years of age were categorised clinically and radiographically by level of periodontal disease experience. These levels were used to divide the sample into groups - individuals without any reduction in periodontal bone level (60%) and those with severe periodontal bone loss (13%) - which were then used in univariate and multivariate logistic regression analyses as dependent variable. Demographic, socio-economic, general health, smoking habits, clinical, and dental care variables were used in the different regression analyses. In the univariate model, age (20-70 years) was found to be correlated with more severe periodontal disease experience (odds ratio: 1.13; 95% CI: 1.10-1.17). The association with periodontal disease was more pronounced for the older age groups (50, 60, and 70 years). A negative financial situation was also related to severe periodontal bone loss when regressed univariately (odds ratio 2.20 [95%: 1.04-4.68]). Moderate-heavy smoking (≥10 cigarettes/day) appeared to be associated with severe periodontal destruction with an odds ratio of 9.78 (95% CI: 3.62-36.42). Of the clinical variables in the univariate model, higher mean levels of supragingival dental plaque and the presence of subgingival calculus were related to more severe periodontal disease with odds ratios of 1.02 (95%: 1.01-1.03) and 2.96 (95%: 1.50-5.88), respectively. When the same variables were regressed multivariately, age (continuous) (odds ratio 1.17 [95% CI: 1.12-1.22]), moderate-heavy smoking (odds ratio 11.84 [95% CI: 4.19-33.50]), and higher mean levels of plaque (odds ratio 1.02 [95% CI: 1.00-1.03]) remained significant. Light smoking (1-9 cigarettes/day) was not significantly associated with severe periodontal disease in the 2 regression models. The present study demonstrated that smoking, greater age, and higher mean levels of plaque are potential risk factors for severe periodontal disease in this specific population.

Tidskriftsartikel (refereegranskat)abstract
- Cross-sectional and longitudinal studies were performed in the community (in this paper changed to city) of Jönköping, Sweden, over a period of 20 years to follow changes in oral health and oral health behaviour. To widen our knowledge about dental health and dental care among the adult population, we expanded the study in 1993 to cover the whole county. The specific aim of the present study was to describe tooth loss (excluding third molars) and periodontal bone level in adult residents of Jönköping County and to compare these two parameters in adults living in the city of Jönköping with the same in adults living in the rest of the county. Random samples of individuals 30, 40, 50, 60, and 70 years old were selected. A total of 484 persons from the city and 1219 subjects from the rest of the county were examined. A total of 32 (7%) and 27 (2%) persons were completely edentulous in the examined populations from the city and from the rest of the county, respectively. A majority belonged to the older age groups, 60 and 70 years, with 17% of the subjects in the city being edentulous compared with 13% in the rest of the county. The mean number of missing teeth in subjects in the city versus subjects in the rest of the county was 0.75/0.95, 1.37/1.60, 3.34/2.43, 6.34/7.40, and 9.95/10.26 in 30-, 40-, 50-, 60-, and 70-year-olds, respectively. Of all the different tooth types, the average number of molars per person decreased the most with increasing age from an average of 7.79/7.83 (city/county) to 3.06/3.09 (city/ county) for 30- and 70-year-olds, respectively. The proportion of subjects without molars was higher in the older age groups in both the city and the rest of the county with 4.8/10.7% and 15.6/22.0% of the 60- and 70-year-olds, respectively, lacking molars. In both populations, the mean periodontal bone level decreased with age. It was concluded that no important differences in tooth loss and periodontal health could be seen between the two populations. When organising dental care, dental health administrators could apply the findings from the population in the city to the entire county.
