- The use of Swedish oral moist snuff is a widespread habit in Sweden. In 1999, 25% of the adult male population and 3.1% of the female population were users of snuff. The aim of the present study was to evaluate how variations in pH and nicotine concentrations of snuff affect the oral mucosa, clinically and histologically, salivary pH and daily nicotine intake in 20 habitual users of loose snuff. The subjects were studied during use of their usual brand, after 12 weeks use of a snuff with lower pH and after another 12 weeks use of a snuff with both lower pH and lower nicotine concentration. Consumption data, oral soft tissue changes, salivary pH and nicotine intake were meas-ured. Further, biopsies were taken from the central part of the clinically observed lesions and histological changes were analysed. The subjects maintained their snuff consumption during the observation periods. The average salivary pH was higher during snuff use than in the morning. Further, it was higher shortly after the snuff was removed than during snuff use. After having switched to the snuff with both lower pH and lower nicotine concentrations, they showed a significant reduction in daily nicotine intake and developed significantly less pronounced clinical and histological changes. These results indicate that nicotine is one of the substances in snuff that has a biological effect on the oral mucosa. However, there also seems to be a synergistic effect between the pH and nicotine concentration in the snuff.

- Objective. The aim of the study was to examine the fracture strength of fully anatomical monolithic high translucent Y-TZP, yttria-stabilized tetragonal zirconia polycrystal, crowns and to compare them with monolithic low translucent Y-TZP crowns in different thicknesses. Materials and methods. 80 standardized crowns were made out of a master model resembling a first mandibular molar made in composite material; 40 crowns made of Lava Zirconia by 3M ESPE, a monolithic low translucent Y-TZP material, and 40 crowns made of Lava Plus by 3M ESPE, a monolithic high translucent Y-TZP material. In each group ten crowns of the thicknesses 1.0 mm, 0.7 mm, 0.5 mm and 0.3 mm were made. All crowns underwent thermocycling and preload to simulate aging and normal wear. Finally the specimens were placed in a testing jig and underwent load to fracture. Results. No significant difference was found when comparing the two materials. When comparing the materials in each thickness a significant difference was found in the 0.5 mm group where the high translucent YTZ-P had a higher mean fracture strength value. A significant difference was seen between the different thicknesses within both groups. The strength increased with added thicknesses. Conclusions. The low translucent and high translucent monolithic YTZ-P perform equally well. The use of high translucent monolithic Y-TZP could result in more aesthetic results and the minimal invasive preparation could lead to a reduction in biological complications. This could be beneficial for the patient since the results suggest that even a thin restoration sustains reasonable load in an in vitro environment. Clinical studies are needed to confirm this suggestion.

Oral disease and psychosocial risk determinants in relation to self-assessments of general health in persons with chronic whiplash-related disorders
- 2003

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.

Adolescents' experiences of participating in a school-based fluoride varnish programme in Sweden.
- 2012
-
Ingår i: Swedish dental journal. - 0347-9994. ; 36:3, s. 133-41

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Population-based health promotion with school-based fluoride varnish programmes is becoming more frequent, as these programmes have been implemented in many parts of Sweden during the last five years. The caries-prevention effect is well studied, but as yet there is no study aimed at adolescents'experiences of these programmes. The aim of this study was therefore to describe how a school-based fluoride varnish programme is experienced by participating adolescents. The study was performed as a qualitative study by conducting four focus-groups interviews. In all, 26 adolescents participated, all aged 15. All the participants had several years'experiences of a fluoride varnish programme at school. The participants were asked to describe their experience of participating in the programme.The analysis of the data from the interviews was carried out according to the principles of phenomenography.The three themes that emerged were"Conceptions in relation to the individual", "Conceptions in relation to the school dental nurse"and "Conceptions in relation to the group and school". The result showed that the adolescents experienced that it was positive to take part in a fluoride varnish programme at school and they regarded the school as an important health promotion arena. In spite of this, there were perceptions that were worth reflecting on for school dental nurses, such as feelings of exposure, peer pressure and a perceived lack of information. To further improve these programmes, and thereby increase population-based dental health promotion, it is important to highlight the role of dental personnel, as they are largely responsible for creating the atmosphere.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Aim: This study compared cool detection thresholds, warm detection thresholds and heat pain thresholds at intra- and extraoral locations and measured the influence of spatial summation. Material and Methods: Thirty healthy individuals (15 females and 15 males), mean age 24.9 years, range 20-31 years) participated in the study. Thresholds for warm detection (WDT), cool detection (CDT) and heat pain threshold (HPT) were measured using a thermotester (MSA–Modular sensory Analyzer, Somedic). The intraoral thermode was custom-made with a 9x9mm square surface. The average of three measurements was recorded. Four intraoral sites (gingival regions 24 and 34, tip of the tongue, lower lip) and two extraoral sites (infraorbitalis, thenar) were measured in each participant. To measure spatial summation, five acrylic covers (tip areas: 0.81 cm2, 0.50 cm2, 0.28cm2, 0.125cm2, 0 cm2) were made to fit the thermode. Five measurements on the tip of the tongue were averaged for each acrylic cover. Results: Of the extraoral sites, the cold detection threshold was significantly higher and the heat pain threshold was significantly lower at the infraorbitalis than at the thenar. Of the intraoral sites, the cold detection threshold was significantly lower at the tongue than at any of the other intraoral locations; the heat pain threshold was significantly lower on the tip of the tongue than on the lower lip. Warm detection and heat pain thresholds rose slightly with increasing thermode size, and this association was more pronounced than for cold detection thresholds. Conclusion: Temperature thresholds differed significantly between several anatomic sites, and the association between size of stimulation area and temperature thresholds was weak.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- In July 2002, a new dental insurance program was introduced in Sweden. For all patients over 65 years, prior approval for all prosthetic work would need to be obtained from the Dental Insurance Office. From October to December 2002, 540 cases were randomly selected for evaluation from the 14,624 applications that had been sent from throughout Sweden to the Dental Insurance Office in Lund. Our aims were to appraise the quality of the radiographic examinations and to compare the quality of the digital with the film (X-ray film) radiographs. The radiographic examinations were evaluated as a whole in relation to the proposed treatment and in detail using specific criteria such as density, contrast, unsharpness, angulation, and receptor position error. The quality variables were evaluated as acceptable or unacceptable. A total of 4,687 intra-oral and 206 panoramic radiographs were evaluated. Thirteen per cent of the intra-oral radiographs and 9% of the panoramic radiographs were taken with a digital technique. Most of the digital radiographs—-70% of the intra-oral and 61% of the panoramic radiographs-—were submitted on microdisk. Twentyeight per cent of the intra-oral digital radiographs, however, were submitted on paper. The radiographic quality in 150 cases (28%) were found to be unacceptable for assessment of the proposed treatment. The most common error-—both in digital and X-ray film radiographs-—was in receptor position. Significantly more errors were found in the intra-oral digital radiographs compared to the radiographs taken with X-ray film. Most of the errors in the digital radiographs were detected in the paper copies. In conclusion, it is possible to improve the radiographic quality in applications for treatment approval, and the dentists had more difficulties with the digital technique than with X-ray film.

Chlorhexidine-containing Glass Ionomer Cement. A Clinical Investigation on the Fissure Caries Inhibiting Effect in First Permanent Molars
- 2005
-
Ingår i: Swedish Dental Journal. - : Swedish Dental Association. - 0347-9994. ; 29:3, s. 89-96
-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Glass ionomer cement with addition of chlorhexidine used as a varnish on tooth surfaces has been shown to reduce the number of inter-proximal mutans streptococci (ms). The effect of a single application of such a varnish containing 2.5% chlorhexidine on occlusal caries development of the first permanent molars on 6-year-old children in a high caries incidence area was investigated. The children were examined according to WHO criteria and 262 children with 2 caries free contralateral molars were selected for treatment. Salivary ms samples were collected using the Strip-mutans (SM) method. After brushing the occlusal surfaces with a toothbrush and pumice in water slurry, rinsing and drying with a cotton roll, glass ionomer cement containing chlorhexidine (GI-CHX) and glass ionomer (GI) were applied randomly with a micro brush and the varnish was covered with occlusal wax. At baseline, the mean defs was 18.18 and DMFS was 0.25 and after one year 18.24 and 0.83 respectively. The salivary ms scores were high or very high (SM 2 and 3) in 85.6% at baseline. At the one-year follow up, the GI-CHX and GI materials could not be detected in the fissures. Also, a large number of fissure sealants had been placed in the molars outside the study protocol; thus 4% of the GI-CHX and GI, and 70% of the untreated were sealed at year one. Overall, there was no significant difference between the caries-reducing effect of GI-CHX and GI, but a trend towards a higher effect was seen for GI-CHX. Excluding the sealed molars the reduction was 74% in the GI-CHX-group, and 71% in the GI-group. Conclusion: Addition of 2.5% chlorhexidine to glass ionomer did not seem to increase the caries-reducing effect of the varnish in this high caries incidence population.

Use of mandibular implant overdentures : treatment policy in prosthodontic specialist clinics in Sweden
- 2003

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The aim was to examine the use of mandibular implant overdentures in Swedish prosthodontic specialist clinics. Questionnaires related to treatment with mandibular implant overdentures during 2001 were sent to the heads of the 30 prosthodontic specialist clinics of the Public Dental Health Service in Sweden. Completed questionnaires were received from 28 (93%). The number of treatments with mandibular implant overdentures varied much among the clinics (0 to 22). Seven clinics had not performed any such treatment, and the median number was 2. The number of fixed implant-supported prostheses was much higher (median value 17, range 4 to 100). The correlation between the number of implant overdentures and fixed implant-supported prostheses in edentulous mandibles was weak (r = 0.33; P = 0.10). The most common anchorage system was ball attachments on two unsplinted implants. The most common reason for the choice of the overdenture treatment was the reduced cost, whereas the patient's main wish to improve denture retention came next. The question whether the demand for implant overdentures had increased during the last few years, was answered with "no" by 19, with "yes" by 5 and with "don't know" by 4 clinics. All but one responded that their attitude to implant overdentures had not changed after the introduction of free pricing in Swedish dentistry. It can be concluded that compared to the rapidly increasing international use of mandibular implant overdentures, this treatment of edentulous patients is rare in Sweden, where fixed implant-supported prostheses still are predominant.
