Antimicrobial effectiveness of polyhexamethylene biguanide on Enterococcus faecalis, Staphylococcus epidermidis and Candida albicans.

Aim To evaluate the antimicrobial activity of 0.2% polyhexamethilene biguanide (PHMB) in root canal models infected with Enterococcus faecalis, Candida albicans and Staphylococcus epidermidis. PHMB was compared in these tests with 2.

Frequency of bacetrial content finding in persistant periapical lesions.

Objectives: To determine the percentage of persistant apical lesions positive for bacterial nucleic acids, to detect microorganisms difficult to cultivate in persistant apical lesions by PCR and relate them to endodontic failure, clinical symptoms and diabetes mellitus.

Materials And Methods: The samples of persistent apical lesions were collected during apicoectomy. Bacterial ubiquitous primer 16S rRNA was used to detect 16S ribosomal RNA in 36 samples.

Electric pulp test threshold responses in healthy incisors, canines, premolars and molars.

The purpose of this study was to determine the range of threshold responses of healthy dental pulps and test the reproducibility of the electric pulp test (EPT). Forty-nine dental students participated in the study. Sound teeth in both arches, except third molars, were included.

The Pattern of Antibiotic Prescribing by Dental Practitioners in Zagreb, Croatia.

Background: Bacterial resistance is considered a consequence of misuse or overuse of antibiotics. Dentistry significantly contributes to this increasing public health problem. The aim of this cross-sectional study was to examine the pattern of antibiotics prescribed by Croatian dentists in Zagreb area.

Radiomorphometric indices of mandibular bones in an 18th century population.

Objective: To estimate four radiomorphometric indices of mandibular bones in an 18th century population sample, and possibly associate the findings with bone mass loss related to sex, age, nutritional habits and pathologies reflecting on the bone.

Design: Thirty-six sculls (31 males, 5 females), recovered from the crypt of Požega Cathedral in Croatia were analyzed. Age estimation was based on tooth wear, and Eichner class was determined according to the number of occlusal supporting zones.

Prevalence of apical periodontitis and quality of root canal fillings in population of Zagreb, Croatia: a cross-sectional study.

Aim: To determine the prevalence of apical periodontitis and assess the quality of endodontic fillings in the population of the city of Zagreb, Croatia.

Methods: A total of 1462 orthopantomograms from new patients at 6 different dental practices was analyzed during 2006 and 2007. The presence of periapical lesions was determined by using the periapical index score (PAI).

Caries prevalence and periodontal status in 18th century population of Požega-Croatia.

Objective: The aim was to examine dental and periodontal status of adult Croatian 18th century population and compare the results with available literature data.

Materials And Methods: 104 specimens from the crypt of Požega cathedral were grouped into three female and three male groups according to age. Caries was determined by visual inspection and dental probe.

[Antibacterial effect of the materials for the root canal filling, bases and material for the cavity fillings].

Aim: To assess antimicrobial effects of the materials used in the endodontic treatment of the teeth.

Methods: The following root-canal fillings were examined: Ketac Endo, AH Plus, Diaket, and gutta-percha, by means of the agar diffusion test. As for the base materials, Zink Oxide/Eugenol cement, glass-ionomere cements Fuji II LC Improved, Ketac Cem, and phosphate cement and Harvard cement were investigated.

A three-dimensional evaluation of microleakage of class V cavities prepared by the very short pulse mode of the erbium:yttrium-aluminium-garnet laser.

The aim of this study was to evaluate microleakage along resin restoration in cavities prepared with an erbium:yttrium-aluminium-garnet (Er:YAG) laser, with and without acid etching, and to compare it with that in diamond-drilled cavities. Thirty intact molars were divided into three equal groups. In the teeth in group I, class V cavities were prepared with a diamond drill.

The temperature changes in the pulp chamber during cavity preparation with the Er:YAG laser using a very short pulse.

Objective: The aim of this study was to examine the temperature changes in the pulp chamber during cavity preparation with the Er:YAG laser (2940 nm) with a very short pulse (VSP).

Materials And Methods: Nine groups of 10 intact molars each were used. One root of each sample was amputated and a thermocouple was inserted into the chamber.

Dose- and mode-dependent effect of halogen dental curing blue light on the V79-cell line.

The aim of this study was to evaluate the time and dose dependent effect of halogen light from dental curing unit on the cell viability, colony-forming ability and proliferation of the V79 cell culture. The investigation included the medium mode (M), exponential (E) and standard (S) illumination mode for 20, 40 and 80 seconds. The viability was determined using the trypan blue exclusion test.

[Temporomandibular disorders and headaches].

Temporomandibular disorder (TMD) is a common name for a series of pathologic conditions with similar signs and symptoms, which can lead to a disturbed and altered function of the stomatognathic system. Most of these conditions are of a multifactorial etiology, which can pose difficulties in obtaining a precise and accurate diagnosis. However, TMD is an ever more common and serious problem in contemporary dental practice and at general medical offices, so a more systematic approach in its diagnosis including data collection and interpretation is necessary.

Estrogen receptors in human pulp tissue.

Objective: The aim of this study was to evaluate the expression of estrogen receptor (ER)-alpha in human pulp tissue.

Study Design: Tissue samples were collected from 51 teeth extracted for orthodontic reasons or from endodontically treated teeth. Immunohistochemical staining was performed with mouse antihuman ER-alpha 1D5 by using the alkaline phosphatase antialkaline phosphatase technique.
