- PURPOSE: The aim of the present investigation was to study the effect of daily use of fluoride dentifrices containing various antimicrobial agents on mutans streptococci (MS) in saliva and approximal dental plaque. MATERIALS AND METHODS: Fifty-nine healthy adolescents, 12-14 years old, undergoing orthodontic treatment with fixed appliances and harbouring high levels of MS in saliva and preferably also in interdental plaque, were randomly distributed into four groups, using dentifrices with: 1) zinc lactate (n = 16), 2) amine fluoride-stannous fluoride (n = 13), 3) triclosan (n = 15), and 4) no antimicrobial agent (control; n = 15). Changes of MS scores versus baseline were determined after 1, 3 and 6 months, using the Dentocult SM Strip mutans test. RESULTS: At the 6-month sampling occasion, the subjects using dentifrice with either amine fluoride-stannous fluoride or triclosan showed a tendency to lower MS scores in interdental plaque (p < 0.05). In saliva and in the 1- and 3-month plaque samples, no changes of MS were detected in any of the four groups. CONCLUSION: This 6-month clinical study showed that dentifrices with various antimicrobial agents only result in small or no changes of the MS scores in saliva and approximal dental plaque in orthodontic patients.

Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Between 1997 -2005 a research and developing work has been carried out in collaboration between Child Health Services, Lyckeby Primary Health Area , County Council of Blekinge and a researcher at School of Health, Blekinge Institute of Technology with purpose to develop health counselling in Child Health Services and to study this process. Corner stones for the collaboration and developing process were a participatory approach, a Health Action process and improvement work evolving from practice. The present report describe the evaluation of improvement for seven years, two initial years as a project and five years in ordinary activity, the impact on health counselling and, strains and obstacles for maintaining. The evaluation suggests that the overall aim for the improvement has been achieved. The studies shows that health counselling is a multi-faced work and therefore actions and improvements can not only focus on the health counselling in the consultations. Several factors interact and influence on the routines for child health services, collaboration and health counselling. The process evaluation showed that the participatory action approach made that the district nurses felt that they “urge on together” to improve the health counselling and reach the goal, although the extra developing work took time. The health action working process and the group meetings developed the request of reflection and discussion. By active participating in the project the district nurses developed awareness, knowledge, skills and methods for action and changing and prerequisites for maintaining and application in the organisation increase. The “outsider” (researcher) is important as a reflection and analysis partner. The improving and changing process needs and takes time, for being emerged and not forced, sustainable and not a dayfly.

- AIM: To investigate the effect of Emdogain Gel (Biora AB, Malmo, Sweden), consisting of a enamel matrix derivative (EMD) in a propylene glycol alginate (PGA) vehicle, on experimentally exposed human pulps and to register postoperative symptoms. METHODOLOGY: Nine pairs of contralateral premolars scheduled for extraction on orthodontic indications were included. Following a superficial pulp amputation performed with a small (016) diamond bur, either EMDgel or a mix of calcium hydroxide and sterile saline was placed at random in contact with the pulp wound. The subjects made records of symptoms and were also interviewed about pain/discomfort by a blinded examiner. After 12 weeks the teeth were extracted, prepared and subjected to light microscopic examination in which the inflammation and newly formed hard tissue in the pulp were analysed. Immunohistochemistry was performed using affinity-purified rabbit anti-EMD polyclonal antibodies. RESULTS: Postoperative symptoms were less frequent in the EMDgel-treated than in the calcium hydroxide-treated teeth, especially during the first six weeks. In the EMDgel-treated teeth, new tissue partly filled the space initially occupied by the gel and hard tissue was formed alongside the exposed dentine surfaces and in patches in the adjacent pulp tissue. EMD was detected in the areas where new hard tissue had been formed. The wound area of the EMDgel-treated teeth exhibited inflammation in the majority of the teeth whereas less inflammation was seen in the calcium hydroxide-treated teeth where the hard tissue was formed as a bridge. CONCLUSIONS: In the EMDgel-treated teeth, postoperative symptoms were less frequent and the amount and pattern of hard tissue formation were markedly different than in the teeth treated with calcium hydroxide. However, the operative procedure and the formulation with EMD in a PGA vehicle do not seem to be effective for the formation of a hard tissue barrier.

Forskningsöversikt (övrigt vetenskapligt/konstnärligt)abstract
- Aim To evaluate the evidence on the formation of a hard tissue barrier after pulp capping in humans. Methodology A PubMed and CENTRAL literature search with specific indexing terms and a hand search were made. The authors assessed the level of evidence of each publication as high, moderate or low. Based on this, the evidence grade of the conclusions was rated as strong, moderately strong, limited or insufficient. Results The initial search process resulted in a total of 171 publications. After reading the abstracts and hand searching the reference lists of the retrieved publications, 107 studies were retrieved in full-text and interpreted. After the interpretation, 21 studies remained and were included in the systematic review and given a level of evidence. No study had a high level of evidence, one study had moderate and 20 studies had a low level of evidence. There was heterogeneity between the studies; therefore, no meta-analysis was performed. The majority of studies on pulp capping using calcium hydroxide based materials reported formation of hard tissue bridging, studies on other pulp capping materials such as bonding agents presented inferior results. The evidence grade was insufficient. Conclusions Insufficient evidence grade does not necessarily imply that there is no effect of a pulp capping procedure or that it should not be used. Rather, the insufficient evidence underpins the need for high-quality studies.

- The purpose of this study was to develop an instrument (SEEK) for the early detection of developmental deficits and/or autistic spectrum disorders among children by the age of 8 months at eight child health care centers in southern Sweden. Health visitors, trained by the research team, screened 312 infants. SEEK captured 5 infants with several points. Twenty-one percent of the infants obtained at least one SEEK point. At the 18-month follow-up, 5 children still showed more obvious signs of developmental problems. The health visitors found SEEK to be very satisfactory and easy and quick to use and its items and questions to be easy to administer. The results have indicated a new systematic methodology to examine infants, which is to be further developed.

20-year follow-up of patients receiving high-cost dental care within the Swedish Dental Insurance System : 1977–1978 to1998–2000

Ingår i: Swedish Dental Journal. - : Swedish Dental Association. - 0347-9994. ; 30:2, s. 77-86

Tidskriftsartikel (refereegranskat)abstract
- The objective was to perform a long-term follow-up study of patients that had received high cost dental care within the Swedish National Dental Insurance System in 1977-1978 with special focus on remaining teeth, periodontal disease progression, change in the prevalence of root-filled teeth and teeth with apical periodontitis as well as the survival of fixed prosthetic reconstructions. All 262 patients who had had their treatment plans sent for approval for high-cost dental care in 4 local health insurance districts and who were sampled for base-line studies in 1977-1978, were offered a free clinical examination including radiographs in 1998. 177 patients (68% of the original sample) could be reached for telephone interview and 104 of them (40% of the original sample) were examined clinically and radiographically. Comparisons were made with records and radiographs from 1977-1978. The analyses were performed with the individual patient as the studied unit. The low progression of severe periodontal disease during the 20-23 year follow-up period and the decrease in number of teeth with apical periodontitis among a majority of the patients examined, indicated that the dental care received resulted in a limitation of dental disease on the individual level. Furthermore 63% of the patients had the fixed prosthetic reconstructions, received after approval 1977-1978, in full extention after 20-23 years. However, more tooth losses were observed among the patients in this study than in similar studies in Swedish general populations over the same decades. Furthermore multiple tooth extractions were significantly more frequent in patients with severe periodontitis at baseline and in patients with less apical periodontitis at follow-up in this study. Thus it seems that tooth extraction not seldom was a treatment choice for teeth with severe periodontitis and apical periodontitis among the patients examined clinically in this study.

Att göra abstrakta begrepp och komplexa situationer konkreta : en avhandling om deltagarbaserad aktionsforskning i svensk vård och omsorg
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This dissertation covers the subject of how abstract concepts and complex situations can be concretized through research together with practitioners. The dissertation is based on four empirical studies. The researcher role, the practitioner participation and the methods for data collection and analysis have varied. In study I the concept ‘Närsjukvård’ was explored to understand how practitioners, managers and politicians in hospitals, primary health care and municipalities interpreted the concept. The researcher acted as consultant who collected data by interviews and questionnaires. Practitioners’ participation was limited. ‘Närsjukvård’ was interpreted as accessibility to hospital beds, accessibility to primary health care, collaboration between care providers and continuity and developed home care. Study II aimed to explore how people experienced leg ulcer care. The researcher acted as a consultant who performed the interviews and analysed the data. Although the informants experienced their encounters with the nurses as satisfying, the study illuminated low participation in the care and low practitioner involvement in issues about daily living with the leg ulcer. The findings were brought back to the informants and the practitioners. The project did not proceed towards development and change. In study III the aim was to explore the Swedish concept ‘trygghet’ by using stories from daily life. Four older women were interviewed and the Story Dialogue method was used together with assistant nurses and registered nurses who participated in data collection and analysis. Two themes emerged: Sense of Security and factors strengthening the Sense of Security. Together with the assistant nurses, areas for improvements were identified. Study IV aimed to explore the discharge planning situation in order to generate ideas for development. Members from a discharge planning network participated in the whole research process. Conditions for a successful coordinated discharge planning situation were a system including: the participation of the patient, the competence of the staff and the support from the organisation. The group arranged a workshop about communication and interdisciplinary collaboration. The findings resulted in a form with self-evaluation questions. In conclusion, this thesis illustrates that it is possible to clarify abstract concepts and complex situations together with practitioners. To do this successfully, sense making activities and to start from practitioners’ experiences and their own context are key factors. The studies illuminate that building trust, relationship and sense of participation are essential in health and social care in general and specifically in the participatory action research process.

Story dialogue as a method to connect theory and practice.
- 2007

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- There is an ongoing debate about how to bridge the gap between theory and practise and use existing theory in everyday practice. To enhance knowledge, understanding and to promote change in clinical practice, Participatory Action Research (PAR) is recommended. PAR is a process of systematic inquiry as its methodology emphasise equality and participation. To promote change in the clinical practice the research is done with those who are concerned by the issue rather than on them. By involving and engaging, PAR brings collective ownership and responsibility of making use of the findings. Methods which emphasise reflection and dialogue help professionals to elucidate concerns about issues in their clinical practise, to challenge the status quo and to change. Story-telling is a tool in knowledge development as narratives are powerful to convey experiences. By using Story dialogue method narratives can be investigated in a systematic way. Dialogue and reflection enhance different ways of viewing a problemand a day to day problem can be examined in a systematic way. This paper is about how to use Story dialogue method with the aim to support professionals to elucidate, investigate and take action towards significant problems in care planning situations. The on-going research is performed in a multi-professional care planning network. The purpose of the network is to develop knowledge about care planning in clinical settings and to reach understanding about how to make care planning holistic. We decided in collaboration to examine what holism is in a care planning situation and used members’ narratives about care planning situations characterised by holism. The members and the researches have met four times. Narratives were investigated by using a structured dialogue, writing insight cards and building categories based on insights from the dialogue. Based on the categories we constructed an observation manual which later on will be tested in practise. This paper presents an on-going research projectwhere researchers and practitioners work together to bridge the gap between theory and practice. By using PAR and Story Dialogue Method the members in the care planning network enhance their collective knowledge and understanding about holism with the purpose to improve care planning in practice.
