- AIM: The aim of this study was to evaluate the effects of non-surgical periodontal therapy on intra-oral halitosis 3 months after therapy.MATERIAL AND METHODS: Sixty-eight adults with intra-oral halitosis were included in a case series. Intra-oral halitosis was evaluated at baseline, and at 3 months after treatment using the organoleptic scores (OLS), Halimeter® , and a gas chromatograph.RESULTS: Significant reductions for OLS (p < 0.01), total sum of volatile sulphur compounds (T-VSC) (p < 0.01) and methyl mercaptan (MM) (p < 0.05) values were found after treatment. Hydrogen sulphide (H2 S) levels were not significantly reduced. The numbers of probing pockets 4 mm, 5 mm and 6 mm were significantly reduced as a result of therapy (p < 0.001). Bleeding on probing (BOP) and plaque indices were also significantly reduced (p < 0.001). For the 34 individuals with successful periodontal treatment (BOP<20% and a ≥50% reduction of total pocket depth) reductions in OLS (p < 0.01) and T-VSC scores (p < 0.01) were found. Eleven individuals were considered effectively treated for intra-oral halitosis presenting with a T-VSC value <160 ppb, a H2 S value <112 ppb and a MM value <26 ppb.CONCLUSION: Non-surgical periodontal therapy resulted in reduction of OLS, MM and T-VSC values 3 months after therapy. Few individuals were considered as effectively treated for intra-oral halitosis.

- Background Limited evidence exists on the efficacy of regenerative treatment of peri-implantitis. Material and Methods Subjects receiving antibiotics and surgical debridement were randomly assigned to placement of autogenous bone (AB) or bovine-derived xenograft (BDX) and with placement of a collagen membrane. The primary outcome was evidence of radiographic bone fill and the secondary outcomes included reductions of probing depth (PD) bleeding on probing (BOP) and suppuration. Results Twenty-two subjects were included in the AB and 23 subjects in the BDX group. Statistical analysis failed to demonstrate differences for 38/39 variables assessed at baseline. At 12 months, significant better results were obtained in the BDX group for bone levels (p < 0.001), BOP (p = 0.004), PI (p = 0.003) and suppuration (p < 0.01). When adjusting for number of implants treated per subject, a successful treatment outcome PD = 5.0 mm, no pus, no bone loss and BOP at 1/4 or less sites the likelihood of defect fill was higher in the BDX group (LR: 3.2, 95% CI: 1.010.6, p < 0.05). Conclusions Bovine xenograft provided more radiographic bone fill than AB. The success for both surgical regenerative procedures was limited. Decreases in PD, BOP, and suppuration were observed.

Journal article (peer-reviewed)abstract
- OBJECTIVES: To assess if (I) the alveolar bone defect configuration at dental implants diagnosed with peri-implantitis is related to clinical parameters at the time of surgical intervention and if (II) the outcome of surgical intervention of peri-implantitis is dependent on defect configuration at the time of treatment.MATERIALS AND METHODS: In a prospective study, 45 individuals and 74 dental implants with ≥ 2 bone wall defects were treated with either an autogenous bone transplant or an exogenous bone augmentation material. Defect fill was assessed at 1 year.RESULTS: At baseline, no significant study group differences were identified. Most study implants (70.7%, n = 53) had been placed in the maxilla. Few implants were placed in molar regions. The mesial and distal crestal width at surgery was greater at 4-wall defects than at 2-wall defects (p = 0.001). Probing depths were also greater at 4-wall defects than at 2-wall defects (p = 0.01). Defect fill was correlated to initial defect depth (p < 0.001). Defect fill at 4-wall defects was significant (p < 0.05).CONCLUSIONS: (I) The buccal-lingual width of the alveolar bone crest was explanatory to defect configuration, (II) 4-wall defects demonstrated more defect fill, and (III) deeper defects resulted in more defect fill.

- Objectives The aim of this study was to assess the long-term efficacy of reconstructive treatment of peri-implantitis intraosseous defects. Material and Methods Peri-implant intraosseous defects were augmented using either an autogenous bone graft (AB) or a bovine-derived xenograft (BDX) in combination with a collagen membrane. Maintenance was provided every third month. Results In the AB group, 16 patients with 25 implants remained at year five. In the BDX group, 23 patients with 38 implants remained. Between baseline and year 5, bleeding on probing (BOP) and probing pocket depth (PPD) scores were reduced in both groups (p < .001). In the AB and BDX groups, mean PPD between baseline and year five was reduced by 1.7 and 2.8 mm, respectively. The difference between groups was significant (p < .001). In the AB group, the mean bone level change at implant level between baseline and years three and five was-0,2 and -0.7 mm, respectively. In the BDX group, the mean bone level change at implant level between baseline and years three and five was 1.6 and 1.6 mm, respectively. The difference between the groups was significant (p < .001). Successful treatment (no bone loss, no probing pocket depth (PPD) > 5 mm, no suppuration, maximum one implant surface with bleeding on probing (BOP) at year five) was obtained in 9/25 implants (36%) in the AB group and in 29/37 implants (78.3%) in the BDX group. Conclusions Reconstructive surgical treatment of peri-implant defects using BDX resulted in more predictable outcomes than using autogenous bone over 5 years.

Book chapter (peer-reviewed)abstract
- Small and large sport clubs, in big cities or in the countryside, need to respond to external pressures created by social, financial and environmental factors. These pressures may come from the commercial environment, communities, national governing bodies, or political stakeholders. This chapter introduces the reader to the current pressures faced by Nordic sport clubs and the entrepreneurs’ role in the clubs’ development through the lens of entrepreneurship, and especially social entrepreneurship. This chapter addresses the role of the entrepreneur in relation to the triple bottom line of corporate social responsibility (CSR)—economy, environment, and society—in the context of Finnish and Swedish team sport clubs by using two football clubs as examples.

Qualifying teacher work : everyday work as basis for the autonomy of the teaching profession
- 2007
-
In: Teachers and Teaching. - 1354-0602 .- 1470-1278. ; 13:3, s. 287-306
-
Journal article (peer-reviewed)abstract
- Teachers' work in tuition-free (non-classroom) time was investigated to see to what degree teachers do work that could be considered as qualifying for the status of professional autonomy. The question arises in Sweden and elsewhere as both teachers and the state actively, and in tandem, strive to professionalise the work of the teacher. Abbott's work on the division of expert labour is taken as a point of departure. Based on data collected by an organisation sampling method, the article describes what teachers do in their tuition-free time. The study data consist of 1166 reports from 59 Swedish teachers' daily work situations in school years 1-12. Qualifying teacher work is related to teachers' ways of handling divergent cases, discretionary work and problem solving. Situations where teachers can use specific professional knowledge are described. One of the main findings is that in 22.2% of the situations studied, such professional knowledge can be applied. This corresponds to at least 7.5 hours of the Swedish teachers' weekly working hours; with the reservation that 10 hours of teachers' weekly 45 hours working time is not examined. This time corresponds roughly with the non-regulated working time, that is, time when the teachers do not have to be at school.

Journal article (peer-reviewed)abstract
- Syftet med denna studie är att analysera lärares och elevassistenters arbete och reflektioner kring bedömningar för lärande i en svensk grundsärskola. Forskning har visat att bedömning för lärande är ett kraftfullt verktyg för att förbättra studieresultat. De teoretiska perspektiven diskuterar begrepp som lärande och samarbete. Studien faller inom ramen deltagande design; forskarna följde fyra team, totalt 20 lärare och elevassistenters arbete genom videoobservation, diskussioner, feedback och föreläsningar om bedömning. Teamen dokumenterade klassrumsundervisning och bedömning av elevernas förmågor i olika ämnen. Empirin i denna studie är baserade på teamens skriftliga texter. Texten analyseras med hjälp av en kvalitativ innehållsanalys och bidrar till forskning om formativ bedömning genom att inkludera lärare såväl som elevassistenter. Resultat visar att båda professionerna har utvecklat sin pedagogiska filosofi och förmåga att ge eleverna feedback, vilket kommer att ge stöd i deras inlärning. Resultaten belyser också diskussionen mellan inlärning och omsorg, vad gäller lärare och elevassistenters uppdrag. En utmaning för teamen är att förena elevernas vårdbehov med läroplanens kunskapskrav och se till att de lär sig inom ett holistiskt perspektiv. Undervisning och utvärdering av elever med omfattande inlärningssvårigheter och i behov av alternativ kommunikation är en annan utmaning för teamen samt medvetenhet om att förändringsprocesser tar tid.

Characteristics of Independent Schools Directed at Students in Need of Special Support : a Study of School Website Presentation
- 2019
-

Journal article (peer-reviewed)abstract
- The aim of the research was to explore how 55 Swedish independent schools, directed at (or limited to) students in need of special support (SNSS), describe their organisation, work and visions. The empirical data of the research consisted of the schools' website presentations, which were processed and analysed in consecutive steps. The results showed that the students' complicated school- and life situations were often combined with disabilities mainly in the neuropsychiatric field. The majority of the schools (76%) practiced both schooling and methods for treatment and care, differentiating their role from the mainstream track. Neuropsychiatric and psychological perspectives had a significant influence, reflected in how the schools describe their daily routines, therapeutic methods of treatment and access to specific categories of staff. Small groups, individual instruction and competent staff were described as specific features. Teaching content and didactic aspects were seldom highlighted. The focus on the websites was on socialisation and subjectification while qualification, i.e. knowledge development, had a more limited role. The study points to a need for further research exploring daily pedagogical practice in more depth and calls for a greater focus on student perspectives. Consequences for learning contexts are discussed in the concluding part of the article. The specialist role, the independent schools in the present study tended to take on are most urgent issues to discuss in an educational context striving for equity and inclusive learning environments.
