Methods: The study population included sixty-two high school students between fourteen and fifteen years of age (thirty males and thirty-two females). The response rate was 76.

Knowledge, Attitudes and Habits Regarding Oral Health in First- and Final-Year Dental Students.

The purpose of the research was to compare oral health behavior and plaque indices between Croatian first-year and final-year dental students. Therefore, 46.9% of first-year and 47% of final-year dental students were surveyed using the Hiroshima University Dental Behavior Inventory (HU-DBI) questionnaire and had their plaque indices determined.

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.

Adverse Effects of Antiepileptic Drug Lamotrigine and Oral Implications: Case Report.

Here, we report on a patient who presented with extensive oral lesions. The treatment with lamotrigine is described.The patient presented with bilateral facial swellings and mental space swelling with actively draining extra oral sinus tract in the central chin area.

Ablative Potential of Er:YAG Laser in Dentin: Quantum Versus Variable Square Pulse.

Objective: The primary objective of this study was to compare the dentin ablation volume and ablation rate of quantum square pulse (QSP), using two different pulse energy settings plus a new digitally controlled dental laser handpiece (X-Runner), with those of variable square pulse (VSP), using three different pulse durations. The secondary objective was to examine, by scanning electron microscopy (SEM), the surface effects of ablation with the different Er:YAG laser modes on the dentin surfaces.

Background Data: The available literature has limited data on the efficiency of different operating modes, pulse durations, and the new digitally controlled handpiece of the Er:YAG laser on human dentin.

ARTICULATOR-RELATED REGISTRATION AND ANALYSIS OF SAGITTAL CONDYLAR INCLINATION.

The purpose of this investigation was to study sagittal condylar inclination values within a uniform sample (Angle class I occlusion) using 'articulator-related registration' and Camper's plane as a reference plane. The study was performed on a sample of 58 Angle class I subjects (mean age 25.1, SD 3.

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.

The Oral Status of Adult Population in the Croatian Town of Knin: a Cross Sectional Study.

The Aim: Epidemiologic studies in many countries show uneven distribution of oral diseases (primarily caries) within the population. This is why more studies are oriented towards specific regions or subpopulations instead of large scale national surveys. The major purpose of this cross sectional study was to obtain relevant data about the oral status of the population of Knin and its surroundings according to the WHO criteria.

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.

Proteomics profiling of keratocystic odontogenic tumours reveals AIDA as novel biomarker candidate.

Background: Keratocystic odontogenic tumour (KCOT) is a benign, yet aggressive odontogenic tumour. Herein, proteome analysis of KCOT lesions in comparison with control patient-matched tissue unaffected by the disease and with inflammatory odontogenic cysts, namely radicular cysts is presented.

Methods: For the proteomics profiling, two complementary proteomics techniques MALDI-MS/MS and LC-ESI-MS/MS were employed.

Prevalence of third molars and pathological changes related to them in dental medicine.

The purpose of this study was to determine the prevalence of third molars in terms of respondents' age. Furthermore it was desired to determine the extent of the manifestation of pathological changes, such as caries, apical lesions, and alveolar bone resorption. This study was based on 500 OPGs of patients from the Faculty of Dentistry, University of Zagreb.

Marginal leakage of class V cavities restored with silorane-based and methacrylate-based resin systems.

Unlabelled: The aim of this study was to compare the microleakage of class V cavities restored by silorane resin with those restored by the methacrylate resin system. Sixty standardized class V cavities were prepared on premolars. The teeth were restored with Filtek(TM) Silorane and Silorane(TM) System Adhesive, Filtek(TM) Silorane and Adper(TM) Easy One and Filtek(TM) Supreme XT and Adper(TM) Easy One.

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).
