    • The goal of this study was to report the long-term effect of different dental health programmes on young adult individuals' knowledge and behaviour relative to oral health. Over a 3 years period, the effect of three different dental health programmes on caries, gingivitis/periodontitis, and knowledge and behaviour concerning oral health in 400 Swedish young adults was evaluated. During the following 2 years, additional prophylactic measures--now based on the individual's symptoms and the prophylaxis previously received--were conducted and evaluated. Five years later still one follow-up was made. The evaluations were based on clinical and radiographic examinations and on a questionnaire survey whose purpose was to study the short- and long-term effects of the different preventive measures, including cost aspects. At the end of the 3 years period, the three test groups exhibited better knowledge and significantly improved behaviour compared with the control group concerning approximal cleaning, from approximately 50% of the individuals at the baseline examination to approximately 90% at the end of the period. Improvement was observed as early as the first year. There were no differences between the test groups. The intensified, individual-related prophylaxis carried out in the following 2 years did not significantly increase knowledge in the test groups; a significant increase in approximal cleaning, however, was found in the control group during this time. At the 10-year follow-up, the individuals' knowledge was undiminished while behaviour concerning approximal cleaning had sunk from 90% to approximately 70% of the individuals. A slight behavioural change concerning number of snacks was found in the course of the study with a shift towards fewer snacks per day. In conclusion, it can be said that simple prophylactic models have an effect on and maintain young adult individuals' knowledge and behaviour concerning oral health and that new knowledge is remembered for long periods of time while changes in behaviour are maintained less well. Moreover, it was found that the scope of the prophylactic programme measured in time and cost had little effect on the long-term result.

  • Secular changes in tooth size and dental arch dimensions in the mixed dentition
  • 2003
  • Ingår i: Swedish Dental Journal. - 0347-9994. ; :157, s. 1-89
  • Tidskriftsartikel (refereegranskat)abstract
    • Secular changes in the mixed dentition were studied. Permanent tooth size and dental arch dimensions were examined in Norwegian children born in the 1960s and 1980s, Swedish children born in the 1960s and 1980s, Norwegian Sami children born in the 1980s, and a sample of Norwegian skulls dating from the 14th to the 19th century. The Norwegian Sami children were nomadic in the summertime. A sample of pigs was studied before and after a maceration process to determine what dimensional changes might occur in such a process. A shrinkage of 0.3%-1.7% was found. This information was used when the skulls were compared with the modern groups. Lateral dental arch lengths were shorter in the children born in the 1960s compared with the children born in the 1980s. This was a result of the higher prevalence of caries in the second deciduous molars in the 1960s groups. Children who had lost a deciduous canine prematurely were found to have smaller dental arch perimeters. When compared with other data, this was blamed on a pre-existing crowding. Permanent tooth size was smaller in the skulls compared with the modern groups. Improved nutrition is considered to be the main reason for the difference. Relative dental arch space differed in the group born in the 1960s from that in the other groups, indicating a greater prevalence of crowding in the former. Relative dental arch space in the skulls and in the group born in the 1980s was similar. A more traditional way of living, as practised by the Sami group in this thesis, was not favorable for relative dental arch space. The transverse intermaxillary relation in boys changed from the 1960s to the 1980s, which indicated that the 1980s group ran a greater risk of developing a posterior cross-bite. Before the same conclusion could be made in the girls, the mesial drift of the first permanent molars had to be corrected for, because of a higher prevalence of caries in the 1960s group. The sex-pooled analysis of the skulls and the contemporary groups revealed that the risk for developing a posterior cross-bite in the 1980s group was greater than in the skulls. The skulls had smaller arch depths than the modern groups.

  • Fixed prosthodontics in adults in Jönköping, Sweden in 1983 and 1993 : An epidemiological study of prevalence and choice of material.
  • 2000
  • Ingår i: Swedish Dental Journal. - 0347-9994. ; 24:3, s. 93-103
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim of the study was to assess the prevalence of fixed prostheses, i.e. single crowns and fixed partial dentures, in adults 20-80 years old in two cross-sectional studies carried out in 1983 and 1993 and to analyse whether the choice of material for fixed prostheses had changed during this time period. The material comprised 586 and 593 individuals. A descriptive analysis of number of individuals with fixed prostheses was made concerning the number of crowns and pontics, the distribution in the jaws, and the materials used. The prevalence of individuals with fixed prostheses was shown to increase with age both in 1983 and 1993. In 1993 the number of individuals with fixed prostheses was slightly lower than in 1983 (44 and 48 percent respectively). There was no difference according to gender. The proportion of individuals with fixed prostheses was lower or almost unchanged in the 20-, 30-, 40-, 50-, 60-, and 80-year-olds in 1993 compared to 1983. In the 70-year-olds, however, the proportion of individuals with fixed prostheses was considerably higher in 1993 compared to 1983. Most individuals with fixed prostheses had a small number of crowned teeth, and about half of the individuals had not more than four crowned teeth. Likewise most individuals with pontics had a small number of pontics. The distributions of crowned teeth and pontics in the jaws were similar in 1983 and 1993. Pontics and crowns were more frequent in the upper than in the lower jaw. Crowns made of porcelain or metal ceramic had increased by 1993 in the 30-80 year age groups, and the study thus confirms general clinical experience that porcelain and metal ceramic are more often the materials of choice in fixed prosthodontics in adults today.

  • Clinical impact of radiological examinations of patients with suspected temporomandibular disorders
  • 2002
  • Ingår i: Swedish Dental Journal. - 0347-9994. ; 26:2, s. 67-74
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim of the present study was to investigate the proportion and diagnostic value of different imaging techniques when investigating patients with suspected temporomandibular disorders (TMD). Out of 396 patients referred to a specialist clinic of stomatognathic physiology, information from radiological examinations was available in 285 patients (72%) at first examination or obtained during the course of treatment. The most common radiographic examination was panoramic radiography. Radiological findings with some clinical importance were made in one-fourth of the 285 patients. In another 11% of these patients, additional radiological findings not judged to be associated with the TMD but in need of therapeutic measures, were made. In 72 patients information from more extensive examinations such as transcranial projections of the TMJs, conventional tomography of the TMJs, CT images and MRT images were performed during the course of treatment. In 63% of these patients, the extended examinations revealed findings of clinical significance for the TMD diagnosis and/or treatment. It is concluded that panoramic radiography has a diagnostic value when investigating patients with suspected TMD. Because of this, and since the effective radiation dose is small for this exposure, and since also no findings on the panoramic radiographs can be an important information, extended use of this examination can be recommended in patients referred to a specialist clinic because of suspected TMD. The need for more extended radiological examinations in TMD patients is limited and should always be based on individual information from the patient's history and/or clinical findings.

  • Ability to estimate oral health status and treatment need in elderly receiving home nursing : a comparison between a dental hygienist and a dentist
  • 2000
  • Ingår i: Swedish Dental Journal. - Swedish Dental Association. - 0347-9994. ; 24:3, s. 105-116
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim of this study was to compare the estimation ability of a dental hygienist to that of a dentist when, independently, recording the oral health status and treatment need in a population of elderly, receiving home nursing. Seventy-three persons, enrolled in a home nursing long-time care programme, were recruited. For the oral examination a newly developed protocol with comparatively blunt measurement variables was used. The oral examination protocol was tested for construct validity and for internal consistency reliability. Statistical analyses were performed using Wilcoxon matched pairs signed rank sum test for testing differences, while inter-examiner agreement was estimated by calculating the kappa-values. Comparing the two examiners, good agreement was demonstrated for all mucosal recordings, colour, form, wounds, blisters, mucosal index, and for the palatal but not the lingual mucosa. For the latter, the dental hygienist recorded significantly more changes. The dental hygienist also recorded significantly higher plaque index values. Also regarding treatment intention and treatment need, the dental hygienist's estimation was somewhat higher. In conclusion, when comparing the dental hygienist's and the dentist's ability to estimate oral health status, treatment intention, and treatment need, some differences were observed, the dental hygienist tending to register "on the safe side", calling attention to the importance of inter-examiner calibration. However, for practical purpose the inter-examiner agreement was acceptable, constituting a promising basis for future out-reach activities.
