Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this study was to analyse how self-assessed general health was related to oral health among persons afflicted with whiplash-associated disorders (WAD), controlling for relevant background factors, confounders and other risk factors. Questionnaires included the SF-36 Health Survey, self-assessed oral health and relevant risk factors, in total 49 questions. Multivariable regression modelling was performed. Members of a nationwide Swedish association enlisting persons who have problems concerning a whiplash injury (n = 1,928) were included. A total of 979 persons participated in the study, a response rate of 50.8%. A multivariable regression model is presented, with general health as the dependent variable, and the independent variables inserted en-bloc. The model was highly significant with an explained variance of 28%. Among background factors, only older age appeared as significantly and strongly related to poorer general health. The strongest explanatory contributions came from the health related variables. Oral disease and extra-oral body pain were both strongly related to poorer general health, most obviously for the oral disease variable. Oral disease was significantly and to a clinically relevant degree associated with self-assessed general health. Several other psychosocial indicators of stress were also significantly related to the general health. These findings are consistent with the stress-behaviour-immune model for development of disease.

- True crystalline ceramic materials presently used in restorative dentistry are Al2O3 (alumina) and yttrium-oxide stabilised tetragonal polycrystalline zirconium-dioxide (Y-TZP). To ensure optimal clinical performance, the dimensions of the Fixed Partial Denture (FPD) framework in general and of the connectors in particular, must be adequate. Considered recommendations for connector dimensions for Y-TZP FPDs vary from 2 to 4 mm in occluso-gingival height and 2 to 4 mm in bucco-lingual width. In order to reduce the fracture probability when designing all-ceramic FPDs, the shape of the connector is an important factor to consider. The radius of curvature at the gingival embrasure plays a significant role in the load-bearing capacity. FPDs with small gingival embrasure radii are subjected to high stress concentrations in the connector area during loading, compared to FPDs with large embrasure radii. The aim of this in-vitro study was to investigate how different radii of curvature in the embrasure of the connector area and different connector dimensions could affect the fracture resistance of 3-unit all-ceramic FPDs made of Y-TZP. Forty-eight FPDs in 6 groups of 8 FPDs with different connector design were produced in Procera Zirconia Bridge material. The FPD cores were subjected to heat treatment to simulate veneering. Following cementation, the FPDs were firstly thermocycled for 5,000 cycles, then preloaded for 10,000 cycles and finally loaded to fracture. All the FPDs fractured in the connector area. All the crack propagation which led to fracture started at the gingival embrasure of the connector. Within the limitations of this in-vitro study,the recommended minimum dimension of an anterior 3-unit all-ceramic FPD of Y-TZP is 3 mm in incisal-cervical direction and 2 mm in buccal-lingual direction. By increasing the radius of the gingival embrasure from 0.6 to 0.9 mm, the fracture strength for a Y-TZP FPD with connector dimension 3 x 3 mm increases by 20%.

- The aim was to develop a comprehensive screening instrument for evaluation of orofacial dysfunction that was easy to perform for different health professionals without special equipment. The Nordic Orofacial Test--Screening (NOT-S), consisting of a structured interview and clinical examination,was developed with a picture manual illustrating the different tasks in the examination. It was first tested in a Swedish version, and later translated to other Nordic languages, and to English. The interview reflected six domains, (I) Sensory function, (II) Breathing, (III) Habits, (IV) Chewing and swallowing, (V) Drooling, and (VI) Dryness of the mouth, and the examination included six domains representing (1) The face at rest, and tasks regarding (2) Nose breathing, (3) Facial expression, (4) Masticatory muscle and jaw function, (5) Oral motor function, and (6) Speech. One or more "yes" for impairment in a domain resulted in one point (maximum NOT-S score 12 points). The mean NOT-S score (+/- SD) in 120 patients (3-86 yr), referred to five centers for specialized dental care or speech and language pathology in Sweden, Norway and Denmark, was 4.1 +/- 2.6, and 0.4 +/- 0.6 in 60 control subjects (3-78 yr). The screening was easy to administer and the time spent 5-13 min. The scores from the clinic-referred sample differed significantly from the controls, and the sensitivity of the screening was 0.96 and specificity 0.63. Repeated evaluations of videotapes of 200 patients by 3 examiners, speech-language pathologists and dentists, with at least two-week intervals, showed inter- and intraexaminer agreement on the points given in the domains at respectively 83% and 92-95% which increased after recalibration to 85% and 95-99%. Kappa values for interexaminer agreement on the NOT-S scores were 0.42-0.44 (i.e. fair), and the method error was 5.3%. To conclude, NOT-S gave a reliable and valid screening for orofacial dysfunction.

- The reported skew distribution of caries prevalence in preschool children, with a small group of children with very high caries prevalence, stresses the importance of early identification for prevention. The present study aimed to describe the caries prevalence in a group of Swedish preschool children and to identify caries risk factors in this population. 221 children, 2 to 3 years old, agreed to participate in the study (82%). A standardized questionnaire was used to describe socio-economic factors, dietary and oral hygiene habits and exposure to fluoride. Initial and manifest dental caries was diagnosed and the presence of plaque was visually observed without disclosing solution. Saliva and plaque samples were collected for identification of mutans streptococci (MS). For statistical analysis,the Student's t-test,the Chi-square test and Fisher's exact test were used. The caries prevalence among the 2 to 3 year-olds was 7 and 18 percent respectively. An association between early childhood caries and a number of factors was found e.g. the presence of MS and visible plaque, nocturnal meals, frequent sugar consumption, mothers' state of employment and immigrant background. The Public Dental Health Service has been successful in decreasing the number of children with caries, but the challenge remains to be able to control caries in the high-risk group. The skew distribution, with many children without caries and a smaller group with very high caries prevalence, was confirmed. The study provided insight into various factors, useful for monitoring children at risk of developing early childhood caries.

Tidskriftsartikel (refereegranskat)abstract
- Syftet med denna studie var att beskriva de examinerade från de fem första kurserna av den problembaserade tandläkarutbildningen i Malmö, deras generella syn på utbildningen och deras professionella situation. Av totalt 166 examinerade (examinerade åren 1995-1999) svarade 128 på den utskickade enkäten. Frågeformuläret inkluderade frågor av demografisk karaktär, de examinerades syn på utbildningen och deras professionella situation. De svarandes medianålder när de examinerades var 26 år (24-43 år) och andelen kvinnor var 56 %. Cirka en fjärdedel var födda utanför Sverige. Två tredjedelar av de svarande angav att de valde tandläkarutbildningen för att de ville bli tandläkare. Nästan samtliga (97 %) arbetade som tandläkare och cirka en tredjedel arbetade utanför Sverige. De som arbetade utanför Sverige var i högre utsträckning också födda utanför Sverige. De svarande menade att utbildningen gav en god förberedelse för deras professionella situation. Deras tillfredsställelse med sin professionella situation, som var hög överlag, korrelerade till deras möjligheter att påverka sin arbetssituation. Cirka en fjärdedel uttryckte intresse för specialistutbildning. När det gällde forskarutbildning uttryckte 64 % av kvinnliga svarande intresse jämfört med 42 % av männen. Vår slutsats är att de svarande överlag var nöjda med sin professionella situation och majoriteten av dem var intresserade av efter- och vidareutbildning.

- Implant treatment is nowadays requested as an alternative mode of treatment for both total and partial edentulousness. The purpose of the study was to assess the maximum number of possible implant sites in a group of adults. The study material comprised 579 persons divided into the age-groups 20, 30, 40, 50, 60 and 70 years. Based on radiological examination, the subjects were grouped according to Eichner's index. They comprised both dentate and edentulous individuals. Templates, marked with cylinder implants of different dimensions, were placed over edentulous regions. The possible number of cylinder-shaped endosseous implants that could be placed anterior to the second molar was assessed in relation to bone availability and anatomical structures. Gaps treated with fixed bridges were not registered. Altogether 1,048 presumptive fixture sites were marked, of which 78% in the age-groups 60 and 70 years. Eichner groups C 1-3, which comprised the edentulous persons, constituted 12% of the subjects and accounted for 57% of the possible number of implants. All edentulous mandibles and 70% of the edentulous maxillae were judged suitable for placement of implants. On average 5.5 and 5.8 sites were marked per edentulous maxilla and mandible, respectively. Groups B1-4 comprised 21% of the subjects and accounted for 37% of the implants. It is discussed that implant treatment in totally edentulous jaws will increase in relative terms in Sweden as in other Scandinavian countries, i.e. the percentage of edentulous jaws treated with implants will increase. In absolute terms, however, the treatment will probably decrease owing to a marked decrease in the number of edentulous individuals. The future need for implant treatment in the residual dentition will probably increase but it is difficult to predict by how much.

- The aim of this study was to obtain an understanding of the factors that affected the way new technology and methods were used in dentistry after a training program. A qualitative research method was used to collect data. Nine dentists working in the Public Dental Service (PDS) in Uppsala County in Sweden agreed to be interviewed in the study. They worked in five different clinics, all with laser equipment, and had received training in the use of lasers.The interviews were tape recorded and transcribed, and were analysed using manifest and latent qualitative content analysis. The categories in this study were identified as "Prerequisites and obstacles to implementation", "Attitudes to laser technology and treatments" and "Laser technology in the future". The dentists described working with lasers as complicated and problematic. They had concerns about the method relating to the working environment, evidence of efficacy of treatment, costs, and benefits for patients and dentists. The main finding was that the decision to adopt the technology seemed to be based on individual perceptions of the value of lasers compared to other ways of achieving the same goal.They provided uniform proposals regarding how an organization should implement new methods, including an emphasis on the importance of preparation and having opportunities to be able to test and evaluate the technology. Another important factor was support from surrounding staff, colleagues and management. Despite all the barriers, the respondents were positive about working with lasers in the future, mainly due to their belief that patients would demand laser treatment. In conclusion both individual and organizational factors affected the extent to which the respondents used the laser.The main finding was the individual perception of the value of lasers compared to other methods which could achieve the same goal.
