- OBJECTIVE: To determine if thinning (<3 mm width) of the lower cortical border of the mandible on dental panoramic radiographs, as well as other clinical risk factors, may provide a useful diagnostic test for osteoporosis in young postmenopausal women. DESIGN: Six hundred and fifty-two subjects (age range 45-70 years) were involved in this multi-centre, cross-sectional study. SETTING: Patients were recruited from centres in Leuven (Belgium), Athens (Greece), Manchester (UK), and Malmo (Sweden). SUBJECTS AND METHODS: The subject's age, body weight, whether the patient took hormone replacement therapy or had a history of low trauma fracture were used to form a clinical osteoporosis risk assessment (the OSteoporosis Index of RISk or OSIRIS index). Each patient also received a dental panoramic radiographic examination. RESULTS: One hundred and forty subjects had osteoporosis involving at least one of the measurement sites (lumbar spine, femoral neck or total hip). Those with osteoporosis tended to have a low OSIRIS score and a thinned cortical mandibular border. The area under the ROC curve for using both cortical width and OSIRIS to predict osteoporosis was 0.90 (95% CI = 0.87 to 0.92). There was a significant improvement in the diagnostic ability of the combined OSIRIS and cortical width test over both tests applied separately (p <0.001). The cost effectiveness of the cortical width and OSIRIS model was improved by using a high specificity threshold rather than high sensitivity. However, this analysis ignores the costs associated with missed cases of osteoporosis. CONCLUSION: Dentists have a role to play in the detection and referral of patients at high risk of osteoporosis.

- BACKGROUND: Almost all (17/20) Swedish counties have pharmaceutical committees that establish recommendations for the use of antibiotic prophylaxis in oral healthcare.Objective To evaluate the evidence for the use of antibiotic prophylaxis in oral healthcare and the agreement between Swedish recommendations and evidence. MATERIAL AND METHODS: We conducted a systematic literature search in PubMed and the Cochrane Controlled Trials Register. The MeSH terms 'antibiotic prophylaxis' and 'dentistry' were used in the database search. Abstracts were reviewed according to specific inclusion and exclusion criteria. A total of 186 articles were read in full text by the four authors independently. Data extraction and interpretation of data was carried out using a pre-defined protocol. In the end, one case-control study was included for evaluation of evidence. RESULTS: The case-control study included patients with specific cardiac conditions. The study reported a 49% protective efficacy (odds ratio: 0.51) of antibiotic prophylaxis for first-time episodes of endocarditis within 30 days of procedure. This result was not statistically significant. The quality of the evidence was low. No studies were evaluated on patients with other medical conditions. The recommendations included several cardiac and other medical conditions for which there is a lack of evidence or no evidence to support the use of antibiotic prophylaxis.CONCLUSIONS: There is a lack of evidence to support the use of antibiotic prophylaxis. To avoid the risk of adverse events from antibiotics and the risk of developing resistant bacterial strains, the use of antibiotic prophylaxis should be minimised and recommendations in Sweden should be revised to be more evidence-based.

Clinical factors and clinical variation influencing the reproducibility of interocclusal recording methods
- 2002

- Objective The reproducibility of clinical records of the occlusion was assessed in three dimensions using mounted casts. Three distinct areas were examined: 1) mandibular positions (intercuspal position (IP) or retruded contact position (RCP)), 2) materials used in recording the occlusion, 3) clinical variation. Design Interocclusal records were made in a random order of three patients: one fixed prosthodontics case, one removable partial denture case and one complete denture case, with two different types of waxes, record rims, two different brands of vinyl polysiloxanes and one irreversible hydrocolloid. Setting Private practice and Karolinska Institute, Huddinge, Sweden, Subjects One general dental practitioner and three voluntary patients. Results Point estimation of variance components indicate that 70-93% of the variation of the positions of the mounted casts are caused by: 1) clinical variation for all three cases and in three directions, 2) the influence of recording materials 0-29%, and 3) mandibular positions (IP/RCP) 0-11%. The ranges of the positions of the mounted casts were lower for the dentate case (0.04-1.39 mm) than for the partially dentate case (0.17-2.65 mm), which in turn was lower than those for the edentulous case (1.42-5.59 mm). Conclusion Clinical variation seems to dominate the variation in positions of mounting casts when making interocclusal records, rather than mandibular position or the recording materials used. Therefore a dentist who makes one single interocclusal record cannot presume that it will reproduce the interocclusal relationship intended, which in the present study was most obvious for the edentulous case. The results showed that impression materials stabilised by a tray did not differ significantly from waxes and record rims concerning the reproducibility. Therefore the stabilised impression materials are an alternative, which also give additional advantages like reduction of appointments as well as superior accuracy.

Does saliva contamination interfere or stimulate regenerative processes applying current biomaterials on oral surgical sites?

- Innovative dental biomaterials have been developed in order to stimulate higher biocompatibility and faster healing times using responsive surfaces for regenerative procedures. However, saliva is one of the fluids to interact with these biomaterials in the first instance. Studies have revealed significant negative effects on the biomaterials' properties, biocompatibility and bacterial colonisation after saliva contact. Nevertheless, the current literature is unclear about the profound effects of saliva on regenerative procedures. The scientific community urges further detailed studies associating innovative biomaterials/saliva/microbiology/immunology in order to clarify clinical outcomes. This paper discusses and provides information about the challenges of research using human saliva, the lack of standardisation in protocols applying saliva, and tentative applications of saliva proteins associated with innovative dental biomaterials.

Retention of prefabricated and individually cast root canal posts in vitro.
- 2003

Tidskriftsartikel (refereegranskat)abstract
- Objectives: The aim of the study was to evaluate the retention of prefabricated root canal posts made of a variety of materials that have recently been introduced into dentistry. Materials and methods: The posts studied were CosmoPost, Composipost carbon fibres, Composipost Æstheti-Plus, Composipost Light-Post, and Para Post Fiber White. The posts were luted in extracted human premolars and the cores were built up with the resin composites recommended by the manufactures. The retention of individually cast gold alloy posts luted with zinc-phosphate cement were used as reference. A universal testing machine was used to determine the retention of each cemented post. Data were compared using ANOVA supplemented with Fisher’s PLSD at a significance level of p < 0.05. Results: Only the CosmoPost system exhibited retention values that were significantly lower then for the conventionally cast gold alloy posts luted with zinc-phosphate cement. The force necessary to loosen the CosmoPost specimens was significantly less than that needed to loosen the Composipost Æstheti-Plus (p < 0.05) and the Composipost Light-Post systems (p < 0.001). The force necessary to loosen the Para Post Fiber White specimens was significantly less than for the Composipost Light-Post system (p < 0.01). Other combinations did not differ significantly (p > 0.05). Conclusions: When zirconium oxide ceramic posts are luted with resin composites the bonding between the ceramic and resin composite seems to be weak. Further studies are thus necessary to achieve improved retention of all-ceramic root canal posts.
