Study showed a lack of knowledge and uncertainty in recognizing and reporting CAN cases in Croatian dentists. They expressed the need for undergraduate and post-graduate continuing education on this issue.

Objectives: To determine the correlation of skeletal bone mineral density (BMD) with mandibular density and mandibular radiographic indices estimated on digital panoramic radiographs. Methods: Study comprised 112 female subjects older than 45 years. Digital panoramic radiographs were taken, and patients were referred to densitometric measuring (dual energy X-ray absorptiometry) of BMD in the hip bones and lumbar spine regions (L1-L4). On the radiographs, mandibular bone density was estimated and the following indices were measured by the DIGORA ® software (Soredex, Tuusula, Finland): mental index (MI), gonial index (GI), antegonial index (AI), panoramic mandibular index (PMI) and alveolar crest resorption degree (M/M). Mandibular cortical index (MCI) was visually estimated. Results: Mandibular density and visual index MCI are significant predictors of hip and spine BMD. Mandibular density was marked by a significant square trend: it decreased until the age of 54 years and remained constant until the age of 64 years when it started to increase. Significant correlations were found between MI, AI and PMI values and BMD in the hip but not in the lumbar spine region. The GI and M/M values did not show statistically significant correlations with BMD of either region. Conclusions: Mandibular bone density and mandibular radiographic indices are useful in detecting patients with decreased BMD. The applicability of orthopantomograms in diagnosing osteoporosis/osteopenia should be recognized as the potential greatest benefit of this everyday diagnostic method in dental practice.

The aim of this study was to assess the pattern of evolution of resistance to antibiotics in Helicobacter pylori isolated from children who underwent upper endoscopy with antral biopsy during a 10-year period (2001-2010). We retrospectively analyzed data of all children (n = 3,008) who underwent upper endoscopy during the observed period at the Children's Hospital Zagreb, a university tertiary medical center. We calculated the rate, antibiotic susceptibility and risk factors for the H. pylori infection in our cohort. Antral biopsy was performed in 2,313 (76.89%) patients. Altogether, 382 (16.51%) children had positive biopsy for H. pylori (histology and/or culture). There was no significant difference in the incidence of H. pylori during 10 years of observation (p = 0.21). Infected children compared to non-infected group were older (p = 0.005), and had more often antral nodularity (p < 0.0001), and duodenal ulcer (p = 0.002). Altogether, 22.4% of treatment-naïve patients had strains resistant to tested antibiotics: majority to azithromycin (17.9%), followed by clarithromycin (11.9%), metronidazole (10.1%) and amoxicillin (0.6%). In the eradication failure group, 9/11 of children had strains resistant to tested antibiotics, mostly to metronidazole (7/11), followed by azithromycin (3/11) and clarithromycin (1/11). No correlation was found between age or gender and antibiotic resistance (p = 0.32, for both). In conclusion, our data strongly support current guidelines which recommend antibiotic susceptibility testing prior to eradication therapy. Based on our results we recommend the use of amoxicillin-metronidazole-based regimen as the first-line therapy in our study population.

Although osteoporosis is not the main cause of periodontitis, it may be a factor that leads to enhanced periodontal pocket depth and greater risk of tooth loss in ageing women.

The aim of the study was to test the hypothesis that there is no difference between the soft tissue profile of Croatian and white North American adults. Facial profile photographs were taken of 110 Croatians (52 males and 58 females) with normal occlusions and well-balanced faces (age 22-29 years). The findings were also compared with a white Brazilian group. An independent Student's t-test (P < 0.05) was used to compare the soft tissue parameters of Croatians with those of North Americans and to assess gender differences. The soft tissue profile measurements that showed significant gender dimorphism (P < 0.001) were the true vertical line [(TVL)-nasal tip (NT)] and TVL-point B, indicating that the males had slightly greater nasal prominence (mean difference: 1.32 mm) and deeper labial sulci (mean difference: 2.04 mm) compared with the females. The upper lip was the same for both genders (1.25 mm), while the lower lip was 0.97 mm more prominent in females than in males. All soft tissue variables, except TVL-NT showed significant differences between Croatian and white American female subjects (P = 0.096). For male subjects, nasolabial angle was the only variable that showed no statistically significant difference between the two populations. A universal standard of facial aesthetic is not applicable to diverse white populations. These differences should be considered in diagnosis and treatment planning for Croatians, together with their individual characteristics.
