Aim. The purpose of this study was to examine and health attitudes/behavior of Romanian dental students (n = 110). Materials and methods. A questionnaire known as HU-DBI (Romanian version) was administered to 110 students in the last year of studies. In the same time was evaluated the prevalence of dental caries and some correspondence between the HU-DBI index and oral health status for every student. The questionnaire was administered after their written informed consent. Dental caries status was evaluated using the world health Organization (WHO) caries diagnostic criteria for decayed, missing and filled teeth and surfaces (DMF-T and DMF-S, respectively). Data were statistically analyzed. Results. The prevalence of dental caries was 60% only 6.7% (8 students) had DMF-T = 0. The mean DMF-T recorded was 7.3 (± 0.35). When relating the different DMF values to the HU-DBI responses, a statistically significant relation was found between seven items and DMF scores of their components and indices. The HU-DBI score ranged from 6 to 12 (mean 9.8). Low DS and DT values significantly correlated with a high total HU-DBI score (p < 0.05); that is subjects with low levels of dental disease had more positive oral health attitudes and behavior. Conclusions. The positive attitude of dental students towards the care of their own teeth and gums is important in determining the oral health conditions of their patients. In passing through the curricles the dental students should be able to set a personal example in oral health.

Miniimplant recently became a way of orthodontic treatment. Compared to the other implants, miniimplants are relatively small, allowing them to be placed between the dental roots in various areas of the jaws and serve as skeletal anchorage for orthodontic tooth movements. The use of miniimplants for orthodontic skeletal anchorage may be an predictable and accurate alternative without requiring patient compliance, compared with conventional versions of anchorage. The paper presents a series of clinical cases seen and treated within the dental office of S.C. RANDI SRL and in the Department of Orthodontics at New York University College of Dentistry.

Orthodontic implants, called mini-implants or temporary anchorage devices, have been designed to meet the needs of orthodontic biomechanics. Having the goal of providing resistance to unwanted tooth movements, anchorage is chosen according to the main factors that influence the quality of orthodontic care. Of these, local factors such as bone quality, space, thickness of the gum, etc. should be correlated with those watching the mini-implant design, geometric and dimensional factors that are taken into account for the stability of the mini-implant. This paper summarizes some of the results of the research aimed to analyze the main factors of stability of mini-implants used for orthodontic anchorage and how to measure it using the mini-implants (design shape and dimensions) and a special equipment for testing the tensile strenghth.
