The aim of this study was to investigate oral health behavior and attitudes of dental students in years 1 to 6 at the University of Zagreb, Croatia. The Croatian version of the Hiroshima University-Dental Behavioral Inventory (HU-DBI) was administered to predoctoral dental students, and collected data were analyzed. A total of 503 students (22.3±2.6 mean age) completed the questionnaire. The response rate was 85.1 percent, and 72.4 percent of the respondents were female. These dental students' answers to eleven out of twenty HU-DBI items differed signiicantly by academic year. The mean questionnaire score was 6.62±1.54, and the highest value of the HU-DBI score was in the fourth year (7.24±1.54). First-year students were most likely to have a toothbrush with hard bristles and felt they had not brushed well unless done with hard strokes. Students in the sixth year were least worried about visiting a dentist and most frequently put off going to a dentist until having a toothache, indicating that rise of knowledge contributes to higher self-conidence. The mean HU-DBI score for these students showed average value, pointing out the need for a comprehensive oral hygiene and preventive program from the start of dental school.Dr. Badovinac is Research Assistant,

Periodontal disease represents a strong, independent, and clinically significant risk factor for PTB in the studied cohort. There are strong indicators that periodontal therapy should form a part of preventive prenatal care in Croatia.

The aim of this study was to determine the prevalence of dental caries, DMFT score and treatment needs in a group of diabetic patients (n = 222), mean age 46.9 yr, and to compare them to those recorded in a control group (n = 189), mean age 43.9 yr, using WHO criteria. Relations between the type and duration of diabetes mellitus, diabetic complications (retinopathy and neuropathy), diabetic control, and the subjects' DMFT status were separately studied. The results obtained revealed no difference in the prevalence of caries between the group of diabetics and the control group. Neither was any difference found in the mean numbers of teeth with fillings, but the number of extracted teeth per subject was significantly higher in the group of diabetics (12.3) than in the control group (9.7) (P less than 0.01). Type I diabetics were found to have a significantly higher number of teeth with fillings (4.05 vs. 2.22) than the non-insulin dependent diabetics (P less than 0.001). Type II diabetics, however, had a significantly higher number of extracted teeth (14.1 vs. 10.4) (P less than 0.001). There was no difference in the caries experience regarding duration of diabetes, diabetic control, or diabetic complications.

The aim of this study was to investigate, using the CPITN system, the periodontal treatment needs in diabetic patients, and to shed additional light on the possible effects of the duration and control of diabetes on the periodontal status in these patients. A comparison was made between 222 diabetic patients (mean age, 46.9 years) and 189 control subjects (mean age, 43.9 years). Edentulous patients were not included in the study. The results indicated that diabetic patients demonstrated significantly more missing teeth (P less than 0.001). The mean number of missing sextants was also significantly higher in diabetics. Pathologic pockets of 6 mm or more were found in 1.3 and 0.3 sextants in the diabetic and control group subjects, respectively (P less than 0.001). Up to the age of 34, no differences were observed between the diabetic and control group subjects regarding pathologic pockets of 6 mm or more. Above this age, diabetics demonstrated significantly more sextants with deep pockets (P less than 0.001). Concerning the type of diabetes, no differences related to CPITN score were found between insulin dependent and non-insulin dependent diabetics. Neither were any differences found in the periodontal condition related to the duration and control of diabetes, whereas diabetics with advanced retinopathy demonstrated more sextants with deep pockets. Oral hygiene instructions and scaling were required in all patients from both study groups. On an average, 1.3 sextants in 50.9% of diabetics and 0.3 sextants in 17.9% of control subjects required complex treatment.
