- In August 23-25, 2007, the Scandinavian Society for Prosthetic Dentistry in collaboration with the Danish Society of Oral Implantology arranged a consensus conference on the topic 'Implants and/or teeth'. It was preceded by a workshop in which eight focused questions were raised and answered in eight review articles using a systematic approach. Twenty-eight academicians and clinicians discussed the eight review papers with the purpose to reach consensus on questions relevant for the topic. At the conference the consensus statements were presented as well as lectures based on the review articles. In this article the methods used at the consensus workshop are briefly described followed by the statements with comments.

- Lysozyme adsorption to charged surfaces was studied by Monte Carlo simulations at different protein concentrations, protein net charges, ionic strengths, and surface charge densities. The lysozyme was represented by a hard sphere with embedded positive and negative surface charges parametrically dependent on the solution pH. A short-range attractive protein-protein potential was included to represent attractive non-Coulomb forces. The charged surface was described by a hard wall with embedded charges representing a mica surface. The protein adsorption was favored by high protein concentration, high protein net charge, low ionic strength, and high surface charge density. Nevertheless, adsorption appeared also for a weakly negatively charged protein to the negatively charged surface as a result of an electrostatically favorable protein orientation at the surface. While a multipole expansion including monopole and dipole moments only was insufficient to explain preferential orientation, an expansion including also quadrupole moments provided a satisfactory picture. Finally, it was found that the short-range attraction between the proteins increased the adsorbed amount, as well as the structure in the adsorbed protein layer. The adsorbed amounts obtained compared favorably with experimental results.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this epidemiological study was to examine associations between temporomandibular (TMD)-related problems and variables from three domains: (1) socio-economic attributes, (2) general health and health-related lifestyle, and (3) dental attitudes and behaviors. The overall response rate to a questionnaire mailed to the total population of 50-year-old subjects in two Swedish counties (8,888 individuals) was 71%. Among the 53 questions in the questionnaire, those related to social, general health, and health-related factors were used as independent variables in logistic regression models. Three TMD-related symptoms and reported bruxism were used as dependent variables. Impaired general health was the strongest risk factor for reported TMD symptoms. Along with female gender and dissatisfaction with dental care, impaired general health was significantly associated with all three TMD symptoms. A few more factors were associated with pain from the TMJ only. In comparison, reported bruxism showed more significant associations with the independent variables. In addition to the variables associated with TMD symptoms, being single, college/university education, and daily tobacco use were also significantly correlated with bruxism. Besides female gender, impaired general health, dissatisfaction with dental care, and a few social and health-related factors demonstrated significant associations with TMD symptoms and reported bruxism.

Tidskriftsartikel (refereegranskat)abstract
- Objective. To assess possible changes in the prevalence of four temporomandibular disorder (TMD) symptoms reported by subjects at age 50 and again 10 years later. Material and methods. Identical questionnaires were sent out in 1992 and in 2002 to all subjects born in 1942 and living in two Swedish counties. Of those who answered the four questions on TMD symptoms in 1992, 74% responded in 2002 (N=4639). The response alternatives were dichotomized into two groups: 1) No problems, and 2) some, rather severe and severe problems. Results. The mean prevalence of TMD-related symptoms reflected small and mainly non-significant changes, whereas the prevalence of reported bruxism was significantly greater at age 60 than at age 50. Among those with no TMD symptoms at age 50, 5-7 % of the men and 8-9% of the women reported symptoms at age 60. Of those reporting one or more TMD symptoms at age 50, 47-65 % of the men and 40-48 % of the women had no symptoms 10 years later. There was a significant and markedly increased risk of reporting TMD symptoms and bruxism (OR > 10) at age 60 among those who had symptoms at age 50. Conclusions. The mean prevalence of reported TMD symptoms was relatively consistent from age 50 to age 60. The group reporting symptoms at the first examination were highly likely still to have the symptoms 10 years later. However, approximately half of the subjects with TMD symptoms at age 50 reported no symptoms at age 60.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Aims: To investigate, by means of a mail questionnaire, the prevalence of symptoms related to temporomandibular disorders (TMD) in 50-year-old subjects living in the counties of Örebro and Östergötland, Sweden. Methods: The total population comprised 8,888 individuals, and the overall response rate was 71%. A clinical evaluation of the masticatory system was performed in subgroups to validate the responses to the questionnaire. There was satisfactory correspondence between self-reports and welldefined clinical conditions. Results: Women reported, more often than men, pain from the temporomandibular joints (TMJs), TMJ sounds, bruxism, sensitive teeth, and burning mouth symptoms. The prevalences of difficulties in jaw opening, loss of anterior teeth due to trauma, and masticatory problems were greater in men than in women. No gender difference was found in the number of remaining teeth. Logistic regression analysis with pain from the TMJ as the dependent variable identified bruxism, impaired chewing efficiency, and gender (women) as the most significant risk factors. With reduced chewing ability as the dependent variable, several missing teeth constituted the highest risk, followed by pain from the TMJ, bruxism, gender (men), and loss of anterior teeth due to trauma. Conclusion: There were significant gender differences in reported TMD-related symptoms in 50-year-old Swedes. Bruxism was a significant risk factor for pain from the TMJ. Reduced number of teeth and pain from the TMJ were significant risk factors for impaired chewing ability.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to determine the changes in prevalence of xerostomia in subjects from 50 to 65 yr of age. Questionnaires were sent to all subjects who were born in 1942 and were living in two Swedish counties in 1992, 1997, 2002, and 2007. The analyses focused on those who answered the questionnaires both in 1992 and in 2007. The response rate was 71.4% (n = 6,346) in 1992 and 73.1% (n = 6,078) in 2007. Of those who answered the questionnaire in 1992, 74.3% (n = 4,714) also responded in 2007. There was an almost linear increase in the prevalence of xerostomia at the four study time-points (i.e. when the subjects were 50, 55, 60, and 65 yr of age). Xerostomia was more prevalent at night than during the day. The pooled prevalence of night-time and daytime xerostomia was 6% at 50 yr of age and 15% at 65 yr of age, and it was higher in women than in men on both occasions. Logistic regression analyses showed that impaired health and smoking were significantly associated with daytime xerostomia but not with night-time xerostomia. Despite the increase in prevalence of xerostomia from 50 to 65 yr of age, there was considerable variation during the observation period. The incidence rate was 13% (507/4,015) and the disappearance rate was 42% (104/250) (dichotomized answers).

Tidskriftsartikel (refereegranskat)abstract
- The aims of this study were first to investigate, by means of a mail questionnaire, variables from three domains: (i) socio-economic attributes; (ii) general and oral health; and (iii) dental attitudes and behaviours in a large sample of 50- and 60-year-old subjects, and second to compare subjects with or without reported temporomandibular joint (TMJ) pain with respect to these variables. In 2002, a questionnaire was mailed to all 50- and 60- year-old subjects in two Swedish counties, Örebro and Östergötland (n =17 138; n 50 = 8878; n 60 = 8260). Individuals not responding within 2 weeks were given a reminder. If still not answering, a new questionnaire was sent. The final response rate was 72.8% (n = 12 468). The reported responses to questions regarding ‘pain in the TMJ region’ and ‘difficulty to open the mouth wide’ were dichotomized into two groups: (i) no temporomandibular disorders (TMD) symptoms; and (ii) some, rather great or severe TMD symptoms. Striking differences in demographic, occupational, general and oral health conditions were found between the groups with and without TMD symptoms. The strongest risk indicator for both pain and dysfunction was reported bruxism. Women, younger subjects (50 years old) and bluecollar workers were significantly more prevalent in the TMD symptom groups. Variables related to impaired general and oral health were more common in the groups with reported TMD problems, whereas satisfaction with received dental care and wlth teeth was lower. Individuals with reported TMD symptoms differed significantly from those without TMD symptoms in socio-economic attributes, general and oral health symptoms, dental conditions and satisfaction with their teeth.

Use of mandibular implant overdentures : treatment policy in prosthodontic specialist clinics in Sweden
- 2003
-
Ingår i: Swedish Dental Journal. - 0347-9994. ; 27:2, s. 59-66

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.
