- Objective: To investigate the amount and pattern of changes of maxillary front teeth 7 years postretention, which previously were retained with a bonded retainer. Materials and Methods: The study group consisted of 27 patients. Study models before treatment (T1), at debonding (T2), 1 year after removal of the upper bonded retainer (T3), and 7 years postretention (T4) were present. The irregularity index (sum of contact point displacements) and the rotations of front teeth toward the raphe line were calculated. Results: The irregularity index of the maxillary front teeth changes very little or not at all during the first year postretention. Further change long term resulted in an irregularity index of mean 2.0 (range 0.0–5.8). The contact relationship between the laterals and centrals seems to be the most critical. Forty rotated teeth in 21 patients were corrected more than 20°. Mean relapse during the first year postretention was 6.7° (range 0.0°–14.7°). Mean changes during 7 years was 8.2° (range 0.0°–19.3°). Conclusions: Relapse of upper front teeth retained with a bonded retainer is minor in both the short and long term. If permanent retention is required after 3 years of retention, it is enough to retain the incisors.

- Less invasive excavation methods have been suggested for deep caries lesions. We tested the effects of stepwise vs. direct complete excavation, 1 yr after the procedure had been carried out, in 314 adults (from six centres) who had received treatment of a tooth with deep caries. The teeth had caries lesions involving 75% or more of the dentin and were centrally randomized to stepwise or direct complete excavation. Stepwise excavation resulted in fewer pulp exposures compared with direct complete excavation [difference: 11.4%, 95% confidence interval (CI) (1.2; 21.3)]. At 1 yr of follow-up, there was a statistically significantly higher success rate with stepwise excavation, with success being defined as an unexposed pulp with sustained pulp vitality without apical radiolucency [difference: 11.7%, 95% CI (0.5; 22.5)]. In a subsequent nested trial, 58 patients with exposed pulps were randomized to direct capping or partial pulpotomy. We found no significant difference in pulp vitality without apical radiolucency between the two capping procedures after more than 1 yr [31.8% and 34.5%; difference: 2.7%, 95% CI (−22.7; 26.6)]. In conclusion, stepwise excavation decreases the risk of pulp exposure compared with direct complete excavation. In view of the poor prognosis of vital pulp treatment, a stepwise excavation approach for managing deep caries lesions is recommended.

- In nursing education, it has been argued that professional socialization is facilitated by clinical experiences where students work together with precepting nurses. However, few studies found have focused on how nurses think and act as preceptors, hence providing a base for professional socialization to occur. Therefore; this study aimed to describe how preceptors mediated nursing as a profession to undergraduate nursing students during clinical practice. This was an ethnographic study guided by symbolic interactionism. A purposeful sampling of 13 precepting nurses was observed during the field work period. In addition, 16 staff nurses, purposively selected, and experienced in precepting, participated in focus group interviews. All text from field notes and interviews were read as a whole and analyzed following the ethnographic approach. Findings illustrated how nursing was mediated as the medical–technical, the administrative, and the caring role. Preceptors aimed for professionalism in their students by teaching the students to reflect on what they can do independently as nurses. Preceptors strived to verbalise their practical knowledge to make theory explicit and contextualize to student nurses. This knowledge can guide implementation of preceptor programmes focusing on the meaning and implications of professionalism.

- Aim. This paper is a report of a study describing conditions for precepting in a Swedish clinical context from the perspective of precepting nurses. Background. Clinical practice is a complex part of nursing education, and registered nurses who are acting as preceptors for nursing students face a number of challenges that need to be addressed during the precepting process. Method. An ethnographic approach guided by symbolic interactionism was used. Data were collected by participant observation and focus group interviews over a ten-month period in 2006–2007. Participants were selected by purposive sampling of 13 staff nurses who were preceptors during the field work period. In addition, 16 staff nurses, experienced in precepting, were purposively selected for four focus groups. Findings. Precepting was found to be a complex function for nurses, influenced by conditions that could be both supportive and limiting in nature. Three themes described these conditions: organization, comprising clinical responsibilities and routines; collaboration, focusing on professional relations and interactions; and the personal perspective, comprising preceptors’ experiences, need for feed back and notions of benefits. Time as a limiting condition reappeared through all categories. Conclusion. It is important to raise the issue of time and its impact on the precepting process. Precepting needs to be further discussed in terms of an integrated nursing competence prioritized by all stakeholders involved in clinical practice. Therefore; efforts should be made to plan nurses’ clinical work so that allocated time for precepting can be facilitated.

- Introduction In the present study, confocal microscopy, a miniflow cell system, and image analysis were combined to test in situ the effect of antimicrobials and alkali on biofilms of Enterococcus faecalis, Lactobacillus paracasei, Streptococcus anginosus, and Streptococcus gordonii isolated from root canals with persistent infections. Methods Biofilms formed for 24 hours were exposed for 5 minutes to alkali (pH = 12), chlorhexidine digluconate (2.5%), EDTA (50 mmol/L), and sodium hypochlorite (1%). The biofilms were then characterized by using fluorescent markers targeting cell membrane integrity (LIVE/DEAD) and metabolic activity (5-cyano-2,3-ditolyl tetrazolium chloride and fluorescein diacetate). In addition, the biofilm architecture and the extent to which coating of the substrate surface with collagen influenced the resistance pattern to the chemicals were also analyzed. Results NaOCl (1%) affected the membrane integrity of all organisms and removed most biofilm cells. Exposure to EDTA (50 mmol/L) affected the membrane integrity in all organisms but failed to remove more than a few cells in biofilms of E. faecalis, L. paracasei, and S. anginosus. Chlorhexidine (2.5%) had a mild effect on the membrane integrity of E. faecalis and removed only 50% of its biofilm cells The effects were substratum-dependent, and most organisms displayed increased resistance to the antimicrobials on collagen-coated surfaces. Conclusions The biofilm system developed here was sensitive and differences in cell membrane integrity and removal of biofilm cells after exposure to antimicrobials commonly used in endodontics was discernible.

- PURPOSE: The aim of this investigation was to evaluate the clinical outcome of two different surgical protocols in the edentulous mandible: submerged and nonsubmerged. Further, the Paragon dental implant with a titanium plasma-sprayed surface was evaluated. MATERIALS AND METHODS: Twenty-nine consecutively treated patients with 168 implants supporting fixed prostheses were included. All but 3 patients were provided 6 implants, placed via nonsubmerged healing on one side and submerged healing on the other. Data were collected from patient records and radiographs. Twenty-four patients participated in the 5-year clinical follow-up examination. RESULTS: After 5 years, all patients still had their mandibular fixed prostheses in function. Cumulative survival rates were 100% for prostheses and 99.4% for implants. However, 3 implants fractured in 1 patient. One submerged implant was lost before loading but no further implants were lost during follow-up. The radiographic bone loss was small for all implants with a mean of 0.14 mm (standard deviation [SD]: 0.37) at 1 year and 0.42 mm (SD: 0.48) at 5 years for nonsubmerged implants and 0.17 mm (SD: 0.32) at 1 year and 0.51 mm (SD: 0.33) at 5 years for submerged implants. Nineteen implants (including the 3 that fractured) presented annual bone loss exceeding 0.2 mm after the first year, yielding a cumulative success rate of 86.2% after 5 years. CONCLUSION: Single-stage surgery was shown to have the same predictability as two-stage surgery in the anterior edentulous mandible. Paragon implants with a titanium plasma-sprayed surface showed a fracture rate of 2.2% and a success rate of 86.2% after 5 years.

- BACKGROUND: New computer numeric controlled (CNC)-milled frameworks for implant-supported prostheses have been introduced. However, no data are available on the precision of fit of these new frameworks. PURPOSE: The purpose of this study is to evaluate the precision of fit of a new CNC-milled framework technique (I-Bridge, Biomain AB, Helsingborg, Sweden) using Brånemark System (Nobel Biocare AB, Göteborg, Sweden) and NobelReplace (Nobel Biocare AB) system implants. MATERIALS AND METHODS: Ten test frameworks were fabricated for one master model for each implant system. Five additional frameworks were fabricated for five different models simulating clinical cases as controls (Brånemark System). The distortion of implant center point positions was measured in x-, y-, and z-axes and in three dimensions by using a contact-type coordinate measuring machine and a computer program developed specifically for this purpose. Mann-Whitney U-test was used to compare differences of distortion within and between the groups. RESULTS: The maximal distortion in arch width (x-axis) and curvature (y-axis) was within 71 and 55 microm for all frameworks, respectively. The mean distortion in absolute figures in x-, y-, z-axes and three dimensions was for "clinical control" frameworks 23, 26, 4, and 34 microm as compared with less than 12, 12, 2, and 17 microm for Brånemark and NobelReplace frameworks, respectively. Control frameworks showed significantly (p < .05) greater mean and range of distortions in x- and y-axes and in three dimensions compared with test frameworks. CONCLUSION: All measured frameworks presented signs of misfit, indicating that no framework had a "passive fit." Frameworks produced in a more routine clinical environment seem to present greater levels of distortion as compared with frameworks produced in a strict test situation. However, all measured frameworks presented levels of precision of fit within limits considered to be clinically acceptable in earlier studies of frameworks placed on abutments.

- Rationale and aim: There is a lack of evidence about how to successfully implement standardized nursing care plans (SNCP) in various settings. The aim of this study was to use the “Promotion Action on Research Implementation in Health Services framework” (PARIHS) to explore important factors and conditions at hospital wards that had implemented SNCPs.Method. We employed a retrospective, cross-sectional design and recruited nurses from four units at a rural hospital and seven units at a university hospital in the western and southern region of Sweden where SNCPs had been implemented. Outcome was measured by means of a questionnaire based on the PARIHS-model.Result: In total, 137 nurses participated in the study. The main factors that had motivated the nurses to implement SNCPs were that they were easy to understand and follow as well as corresponding to organisational norms. The SNCPs were normally based on clinical experience, although research more frequently formed the basis of the SNCPs at the university hospital. Internal facilitators acted as important educators, who provided reminders to use the SNCP and feedback to the SNCP users. The patient experience was not considered valuable. Those who claimed that the implementation was successful were generally more positive in all measurable aspects. The use of SNCPs was rarely evaluated.Conclusions: Clinical experience was considered important by the nurses, while they attributed little value to the patient experiences. Successful implementation of research based SNCPs requires internal facilitators with knowledge of evidence-based nursing.
