- BACKGROUND: This systematic review assesses the effect of methods commonly used to manage the pulp in cases of deep caries lesions, and the extent the pulp chamber remains uninfected and does not cause pulpal or periapical inflammatory lesions and associated tooth-ache over time.STUDY DESIGN: An electronic literature search included the databases PubMed, EMBASE, The Cochrane Central Register of Controlled Trials and Cochrane Reviews from January 1950 to March 2013. In addition, hand searches were carried out. Two reviewers independently evaluated abstracts and full-text articles. An article was read in full if at least one of the two reviewers considered the abstract potentially relevant. Altogether, 161 articles were read in full text. Of these, 24 studies fulfilled established inclusion criteria. Based on studies of at least moderate quality, the quality of evidence of each procedure was rated in four levels according to GRADE.RESULTS: No study reached the high quality level. Twelve were of moderate quality. The overall evidence was insufficient to assess which of indirect pulp capping, stepwise excavation, direct excavation and pulp capping/partial pulpotomy, pulpotomy or pulpectomy is the most effective treatment approach for teeth with deep caries.CONCLUSIONS: Because of the lack of good studies it is not possible to determine whether an injured pulp by deep caries can be maintained or whether it should be removed and replaced with a root canal filling. Both randomized studies and prospective observational studies are needed to investigate whether a pulp exposed to deep caries is best treated by measures intended to preserve it or by pulpectomy and root filling.

Journal article (peer-reviewed)abstract
- This study comprises a survey of Swedish dentists'treatment preferences in cases of carious exposure of the dental pulp in adults.The survey was conducted as part of a comprehensive report on methods of diagnosis and treatment in endodontics, published in 2010 by the Swedish Council on Health Technology Assessment. A questionnaire was mailed to a random subsample of 2012 dental offices where one dentist at each office was requested to answer all questions. Each questionnaire contained one of three sets of questions about endodontic practice routines.Thus around one-third of the subsample received case-specific questions about treating carious exposure. Only general practitioners aged below 70 years were included.The final study sample comprised 412 participants.The dentists were presented with two case scenarios. In Case 1 a 22-year old patient had a deep carious lesion in tooth 36 and in Case 2 a 50-year old patient had a deep carious lesion in tooth 14.The participants were asked to nominate their treatment of choice: pulp capping, partial pulpotomy or pulpectomy. For Case 1, 17 per cent of the respondents selected pulpectomy; the corresponding rate for Case 2 was 47 per cent. Female gender and age group 25-49 years were predictive of selection of less invasive treatment options. However, according to recent guidelines (2011) from the National Board of Health and Wellfare, Swedish dentists are recommended to elect pulpectomy prior to pulp capping/partial pulpotomy when confronted with a tooth having a cariously exposed pulp in adults.

Diagnosis of the condition of the dental pulp: a systematic review. International Endodontic Journal, 45, 597613, 2012. Abstract The aim of this systematic review was to appraise the diagnostic accuracy of signs/symptoms and tests used to determine the condition of the pulp in teeth affected by deep caries, trauma or other types of injury. Radiographic methods were not included. The electronic literature search included the databases PubMed, EMBASE, The Cochrane Central Register of Controlled Trials and Cochrane Reviews from January 1950 to June 2011. The complete search strategy is given in an Appendix S1 (available online as Supporting Information). In addition, hand searches were made. Two reviewers independently assessed abstracts and full-text articles. An article was read in full text if at least one of the two reviewers considered an abstract to be potentially relevant. Altogether, 155 articles were read in full text. Of these, 18 studies fulfilled pre-specified inclusion criteria. The quality of included articles was assessed using the QUADAS tool. Based on studies of high or moderate quality, the quality of evidence of each diagnostic method/test was rated in four levels according to GRADE. No study reached high quality; two were of moderate quality. The overall evidence was insufficient to assess the value of toothache or abnormal reaction to heat/cold stimulation for determining the pulp condition. The same applies to methods for establishing pulp status, including electric or thermal pulp testing, or methods for measuring pulpal blood circulation. In general, there are major shortcomings in the design, conduct and reporting of studies in this domain of dental research.

- Petersson A, Axelsson S, Davidson T, Frisk F, Hakeberg M, Kvist T, Norlund A, Mejare I, Portenier I, Sandberg H, Tranaeus S, Bergenholtz G. Radiological diagnosis of periapical bone tissue lesions in endodontics: a systematic review. International Endodontic Journal, 45, 783801, 2012. Abstract This systematic review evaluates the diagnostic accuracy of radiographic methods employed to indicate presence/absence and changes over time of periapical bone lesions. Also investigated were the leads radiographic images may give about the nature of the process and the condition of the pulp in nonendodontically treated teeth. Electronic literature search included the databases PubMed, Embase and CENTRAL from January 1950 to June 2011. All languages were accepted provided there was an abstract in English. The MeSH terms were Cone beam computed tomography (CBCT), Radiography, panoramic, Periapical diseases, Dental pulp diseases, Sensitivity and specificity, receiver operating characteristics (ROC) curve, Cadaver, Endodontics and Radiography dental. Two reviewers independently assessed abstracts and full text articles. An article was read in full text if at least one of the two reviewers considered an abstract to be potentially relevant. Altogether, 181 articles were read in full text. The GRADE approach was used to assess the quality of evidence of each radiographic method based on studies of high or moderate quality. Twenty-six studies fulfilled criteria set for inclusion. None was of high quality; 11 were of moderate quality. There is insufficient evidence that the digital intraoral radiographic technique is diagnostically as accurate as the conventional film technique. The same applies to CBCT. No conclusions can be drawn regarding the accuracy of radiological examination in identifying various forms of periapical bone tissue changes or about the pulpal condition.

Hållbarhetsutvärdering av byggnader : Case Ripan i Kiruna
- 2018

Reports (other academic/artistic)abstract
- Sustainability includes several parameters, and these can be measured and valued in many different ways. This study focuses on balancing the various parts to achieve sustainability by minimizing energy for heating and energy to produce the materials used in the building as well as minimizing cost for material investment and cost for heating using optimization techniques. This is balanced together with the environmental impact. This report describes an initial study for sustainability optimization of a smaller building. The goal is to develop a comprehensive approach to provide a broader basis of decisions for new construction.The calculation included the building envelope (exterior walls, roof and floors), interior walls and stabilizing elements for different frames of wood (timber frame and CLT).The result from the Ripan Case shows that the timber frame design has the lowest embodied energy and operating energy, and lowest cost for investment and heating during the operating phase. The environmental impact of the timber frame design was also low.

Einstein@Home all-sky search for periodic gravitational waves in LIGO S5 data
- 2013
-
In: Physical Review D (Particles, Fields, Gravitation and Cosmology). - 1550-2368. ; 87:4
-
Journal article (peer-reviewed)abstract
- This paper presents results of an all-sky search for periodic gravitational waves in the frequency range [50, 1190] Hz and with frequency derivative range of similar to[-20, 1.1] x 10(-10) Hz s(-1) for the fifth LIGO science run (S5). The search uses a noncoherent Hough-transform method to combine the information from coherent searches on time scales of about one day. Because these searches are very computationally intensive, they have been carried out with the Einstein@Home volunteer distributed computing project. Postprocessing identifies eight candidate signals; deeper follow-up studies rule them out. Hence, since no gravitational wave signals have been found, we report upper limits on the intrinsic gravitational wave strain amplitude h(0). For example, in the 0.5 Hz-wide band at 152.5 Hz, we can exclude the presence of signals with h(0) greater than 7.6 x 10(-25) at a 90% confidence level. This search is about a factor 3 more sensitive than the previous Einstein@Home search of early S5 LIGO data.
