Objectives: The aim of this study was to determine a correlation between the incidence of signs and symptoms of TMD in children aged 12-18 who do not wear a fixed orthodontic appliance and the incidence of signs and symptoms of TMD in children who wear a fixed orthodontic appliance.

Material And Methods: The total number of 120 subjects were included in this survey and divided into two groups.

Radiological Evaluation of Dental Age Assessment Based on the Development of Third Molars in Population of Bosnia and Herzegovina.

Objectives: The development of third molars can be helpful in dental age estimation of adolescents and in early adult period. We tested the repeatability and accuracy of the three dental age radiographic methods (Olze, Demirjian and Solari and Abramovitch) and evaluated which method is more useful. We also aimed at testing to find the correlation of estimated dental and chronological age by these three methods.

Evaluation of Solubility of Luting Cements in Different Solutions.

Objective: To evaluate and compare the solubility of three luting cements in three different solutions: distilled water and artificial saliva with different pH values (7.4 and 3.0).

Socioeconomic Status as Oral Health State Determinant of the Active Working Displaced Persons and Domicile Inhabitants.

Introduction: Socioeconomic changes have a significant impact on the health of the population. Socioeconomic development of society is one of the basic determinants of the health condition and needs of the individual and in the population as well.

Aim: To explore the existence of differences in indicators of oral health status between the displaced persons and domicile population, considering the socioeconomic status (SES) of the respondents.

The Influence of Gender on the Cortical Width of the Lower Border of the Mandible and the Mandibular Cortical Index.

Objective: To evaluate the influence of gender on the mental index (MI) and the mandibular cortical index (MCI).

Methods: In this study, there were 120 subjects (43 male and 77 female subjects), who had undergone a dental panoramic radiograph examination for the needs of diagnosis and future treatment planning. MI and MCI were determined by orthopantomograph.

Evaluation of the water sorption of luting cements in different solutions.

Objective: To evaluate and compare the water sorption of three luting cements in three different solutions: distilled water and artificial saliva with different pH values (7.4 and 3.0).

Measurements of Implant Stability Following Sinus Lift: A Pilot Clinical Study.

Aim: The aim of this study was to evaluate the implant stability of Bredent Sky Blue implants of different diameters following one stage sinus lift procedure.

Material And Methods: This study included 9 male patients with an existing indication for unilateral or bilateral sinus lift procedure. As grafting materials, combination of allograft material MinerOss® cortical & cancellous and Ossceram nano were used.

Biomechanics of cervical tooth region and noncarious cervical lesions of different morphology; three-dimensional finite element analysis.

Objective: The present study aims to investigate the influence of presence and shape of cervical lesions on biomechanical behavior of mandibular first premolar, subjected to two types of occlusal loading using three-dimensional (3D) finite element method (FEM).

Materials And Methods: 3D models of the mandibular premolar are created from a micro computed tomography X-ray image: model of sound mandibular premolar, model with the wedge-shaped cervical lesion (V lesion), and model with saucer-shaped cervical lesion (U lesion). By FEM, straining of the tooth tissues under functional and nonfunctional occlusal loading of 200 (N) is analyzed.

Radiographic Evaluation of Crestal Bone Loss Around Dental Implants in Maxilla and Mandible: One Year Prospective Clinical Study.

Purpose: The aim of the study was to analyze the amount of maxillary and mandibular crestal bone loss around Bredent Sky Blue type of implants of different dimensions one year after implantation.

Materials And Methods: 36 implants of diameter 3.5 x 10 mm were inserted in the maxilla and 12 in the mandible.

Analysis of the abfraction lesions formation mechanism by the finite element method.

Introduction: An abfraction lesion is a type of a non-carious cervical lesion (NCCL) that represents a sharp defect on the cervical part of tooth, caused by occlusal biomechanical forces. The largest prevalence of the NCCL is found on the mandibular first premolar. The goal of the study is, by means of a numerical method - the finite element method (FEM), in an appropriate computer program, conduct a stress analysis of the mandibular premolar under various static loads, with a special reference to the biomechanics of cervical tooth region.

Comparative advantages and shortcomings of corticosteroids in comparison with xylocaine-based perineural blocks in treatment of Bell's palsy.

Introduction There are no established doctrines for treating Bells facial nerve paralysis (Bell's palsy), as there are still controversies in relation to the etiology of the disease. According to available sources 75% of all patients experience minor damage to the myelin sheath, thus usually recovering spontaneously and with no particular treatment. However, the rest of the patients may, without adequate treatment, experience a host of serious complications, starting from prolonged weakness of facial muscles, syncretism, hyperkinesias, contractions, even complete paralysis of facial muscles.

Osteometry of mandibular joint surface.

Anatomically and functionally, temporomandibular joint (articulatio temporomandibularis) is specific, It consists of incongruent joint surface. The size of mandibular joint surface and its position in relation to facies articularis fossae mandibularis in different positions of mandibulae (central occlusion, central relation) are still subject to the interest of prosthetics. The aim of the research is measuring the lower joint surface by special 3D device that enables acribic precise measuring.

Position of mandibular joint surface in cenrric relation.

The position of mandible in centric relation is the initial position in prosthodontic rehabilitation. This fact is especially significant today when, due to development of implantology, the use of osseointegrated prostheses is increasingly discussed. The aim of the study is to define if the peak of the articulating surface of mandible in centric relation position is directed towards the zenith of madibular fossa, or is in the retroposition.
