A sample of 40 permanent single-rooted teeth was used. The coronal part of each tooth was removed at the amelo-cement junction. Teeth were divided into four groups of 10 teeth each. Root-canals of the first and second group were cleaned and shaped by “double flare” technique while “step-back” technique was performed in the third and fourth group. All root-canals were irrigated with 2.5% NaOCl during instrumentation. Prepared root-canals of the first and third group were filled with gutta-percha points and eucapercha sealer by the cold lateral condensation technique while in the second and fourth group Roeko seal® was used as a sealer instead of eucapercha during filling procedure. Filled roots were stored in NaCl 3% at ...

In patients at risk, such short lasting bacteriemia is sufficient for the development of infectious endocarditis. In everyday practice we encounter patients at risk for IE referred to oral surgery (most often tooth extraction) at the Oral Surgery Division, Department of Facial, Maxillary and Oral Surgery, Dubrava University Hospital. Majority of these patients are given IE prophylaxis according to the latest AHA recommendations. For some patients we first consult a cardiologist due to the underlying disease, and as a rule these patients return with cardiologist's advice on IE prophylaxis. We noticed that these recommendations differ between cardiologists. Some cardiologists have for years been recommending the same "prophylaxis" which is not in accord with AHA guidelines. From the available cardiac records we analyzed antibiotic IE prophylaxis before oral surgery in cardiac patients at risk recommended by cardiologists in four Zagreb hospitals in 2003. We collected in total 17 recommendations prescribed by 12 cardiologists. Regretfully, none was in accord with valid AHA guidelines from 1997. Only 6 out of 17 recommendations are in agreement with the outdated guidelines from 1994, which also raises concern. Therefore, we thought it was worthwhile to present these cases, hoping this will stimulate discussion on common guidelines for the benefit of patients at risk for IE.

Root canals of 40 extracted human teeth were instrumented with a size R25 Reciproc instrument. Specimens were randomly divided into two groups (n = 20) according to the root canal filling material. In the first group, root canals were obturated with AH Plus sealer and Reciproc R25 gutta-percha. In the second group, a combination of bioceramic gutta-percha (TotalFill BC) and bioceramic sealer (TotalFill BC) was used. After one week, the retreatment of all specimens was performed using Reciproc instruments. To analyze the differences in the filling remnants, specimens were scanned in a micro-CT device after obturation and after the retreatment procedure. Statistical analysis was performed using the Mann–Whitney U test (p < 0.05). A combination of bioceramic sealer and bioceramic gutta-percha was more effectively re...

Dental appearance plays an important role in practically all personal social interactions. The main factors that define the dental appearance are tooth colour, shape and position, quality of restoration, and the general position of the teeth in arch, especially in the anterior region. The aim of this study was to evaluate the impact of dental status (tooth shape, fracture, dental and prosthetic restorations and presence of plaque) on patient''s satisfaction with the dental appearance, controlling for the age and gender. Methods. A total of 700 Caucasian subjects (439 women) aged 18?86 (median 45 years) participated in the cross-sectional study. Study included clinical examination and self-administrated questionnaire based on selfperceived aesthetics and satisfaction with the appearance of their maxillary anterior teeth. Results. A regression analysis demonstrated that presence of dental plaque, tooth fracture, composite fillings and crowns had significant ind...

Among numerous sociodental indicators the Oral Impacts on Daily Performance (OIPD) is one of the most broadly applied. The aim of this study was to develop and test psychometric properties of a Croatian version of OIDP scale. Methods. The OIDP instrument was translated from English to Croatian in a forward-backward method. The Croatian version was tested for reliability, construct validity and responsiveness on a sample of 702 participants (255 men), aged 18-86 years. Results. Internal consistency of Croatian version of the OIDP was acceptable (alpha = 0.80) and 69.4% of the examinees had oral impacts relating to one or several performances. The most frequently affected performance was eating (53.7%). The test-retest reliability was high (r = 0.99; 95% CI: 0.97-0.99), the mean difference between the OIDP summary scores in two-week interval was not statistically significant. In construct validity testing there was statistically significant correlation between OIDP and...
