The Serbian version of CFSS-DS questionnaire is reliable and valid psychometric instrument for evaluation of dental fear in Serbian children. Dental anxiety negatively affects dental attendance and oral health of the examined schoolchildren.

Web applications security is one of the most daunting tasks today, because of security shift from lower levels of ISO OSI model to application level, and because of current situation in IT environment. ASP.NET offers powerful mechanisms to render these attacks futile, but it requires some knowledge of implementing Web application security. This paper focuses on attacks against Web applications, either to gain direct benefit by collecting private information or to disable target sites. It describes the two most common Web application attacks: SQL Injection and Cross Site Scripting, and is based on author?s perennial experience in Web application security. It explains how to use ASP.NET to provide Web applications security. There are some principles of strong Web application security which make up the part of defense mechanisms presented: executing with least privileged account, securing sensitive data (connection string) and proper exception handling (where the new approach is presented using ASP.NET mechanisms for centralized exception logging and presentation). These principles help raise the bar that attacker has to cross and consequently contribute to better security.

Oral infections and dental caries are still considered as a serious public health problem. Using the method of minimum inhibitory concentrations (MICs), the aim of this study was to investigate the inhibitory effects of 16 plants on the growth of Actinomyces odontolyticus, Streptococcus mitis, Streptococcus sanguinis, Eikenella corrodens, Fusobacterium nucleatum, Lactobacillus acidophilus and Streptococcus mutans. The most effective were ethanol extracts of Rosmarinus officinalis, Salvia officinalis, Thymus vulgaris, Calendula officinalis and Hypericum perforatum. The least efficiency was observed for Acorus calamus extract. Plant extracts could be used in oral health as therapeutic and prophylactic approach or in balancing oral microbiota.

The concept regeneration technique with PRP and with the stimulating influence of platele activated growth factors results in the regeneration of deep periodontal tissue as an important prerequisite for the successfull treatment of gingival recession.

Background/Aim. The shortcomings of the orthopantomography (OPG) method and radiographic misinterpretations may lead to poor treatment planning and complications during or after the third molar extraction. The aim of this study was to determine the validity and reliability of OPG findings concerning post-extraction wisdom tooth root morphology, as well as whether the degree of clinical expertise affects assessment accuracy. Methods. The cross-sectional study included 200 patients who were referred for third molar extraction. Preoperative OPGs were evaluated by examiners classified by their level of experience into three groups: students, residents, and professors. True root morphologies were recorded after the extraction, and the accuracy of the assessment was evaluated using various statistical tests. Results. The majority of assessments were accurate for the lower and upper third molars with a single root. The professor group was the most accurate when compared to the other two groups (p = 0.0015). Weighted Kappa values for intra-respondent accuracy gradually increased from the student to professor group (0.06, 0.28, 0.34, respectively). The highest discrepancy in inter-respondent accuracy was determined between the student and professor groups (poor; ?w = 0.25584). Conclusion. In this study are not achieved results which confirm reliability of panoramic acquisition for detection of accurate third molars root morphology. The level of clinical experience affects diagnostic accuracy, but complex clinical cases should be evaluated by different methods.
