Dens invaginatus is usually diagnosed by standard radiological methods (RVG, OPG, and 3DCBCT). Clinical examination may reveal a mottled, dilated or conical shape of the crown. Endodontic treatment of dens invaginatus can be difficult and complex due to the deviated anatomy. This report describes the successful endodontic treatment of a maxillary lateral incisor that had dens invaginatus and a large periapical lesion. Clinical examination in a 30-year-old patient revealed an acute periapical abscess, and a dens invaginatus type II was diagnosed after radiography. Due to the existing anatomy, endodontic treatment of the main canal was performed through two access cavities, which enabled chemo-mechanical treatment and access to all parts of the root canal. The canal of the invaginated tooth was treated through the third access cavity.

Materials and Methods: Patients with the loss of a first molar in the posterior region were selected for the study. Fabrications of FRC structures were made of longitudinal and woven fibers and ceramic optimized polymer material was used for veneering. Statistical Analysis Used: The restorations were evaluated using the modified United States Public Health Service (USPHS) parameters system for the clinical evaluation of dental restorative materials. Kaplan–Meier survival test was used for analyzing the data. Results: During the evaluation period, no fracture of the FRC construction was found. At all tested restorations, significant color change of the Ceromer veneering material was observed. During the investigation time, the color of the restorations became slightly lighter, with loss of gloss. In two patients, a chip off from the veneered material was noticed after 4 years, in three patients over 5 years and in three patients after 6 years. Conclusions: FRC–Ceromer inlay fixed prosthetic restorations for a period of 7 years showed acceptable clinical durability and functionality.

However, the fact that one of its main components is mercury is the cause of the intensive discussions about the safety of these restorative materials and during the last 150 years polarizes the professional and scientific circles. Proamalgamists consider amalgam safe and useful material, but antiamalgamists mark it as cause of the whole spectrum of diseases. The wish of the authors was that, through the presentation of the literature published from the nineties of the last century to date, present the review of this very issue, which still causes the dilemma in the modern dentistry.

However, the fact that it contains elemental mercury causes doubts about the safety of its application and potential impact on the patient's organism. Due to corrosion of amalgam, which always happens in the oral cavity, mercury is being released, and is distributed in the organism of amalgam fillings carriers. The objective of this study is to analyze the electrochemical behavior of five dental amalgams, unpolished and polished, in the four electrolytic solutions (0.9% NaCl, acetate buffered 0.9% NaCl, and artificial saliva with and without bovine serum albumin), to examine the impact of pH, protein content and polishability of amalgams on their corrosion behavior. Material and methods: The experimental material was tested by cyclic voltammetry method. Conclusion: In the conclusion it is pointed out that corrosion of dental amalgam is always happening and that its volume depends on the tes...

Materials and Methods Three-dimensional models of the mandibular premolar are created from a microcomputed tomography images. An abfraction lesion is modeled on the tooth. The stress of the dental tissues and six restorative materials under functional and nonfunctional occlusal loading of 200 (N) are analyzed by finite element method. Statistical Analysis CTAn program 1.10 and ANSYS Workbench (version 14.0) were used for analysis. Results are presented in von Mises stress. Results Oblique loads caused ≈ four times higher stress in restorative materials than the axial ones. It is noticeable that high values of von Mises stress are measured at the botto...

Therefore, it is assumable that the registration of structural changes of teeth color in different enviromental conditions may prove useful within forensic taphonomy field, for example, for verification of burial environment and postmortem interval (PMI). Registration of very smal alterations of teeth color is nowadays possible due to well developed dental spectrophotometers. It is known that teeth exposed to air quickly dehydrate, but the degree and the pattern of these color changes in time intervals have not been objectively measured. Purpose: The objective was to determine the degree and patern of color alterations of teeth exposed to three different conditions in time. Material and Methods: The impacted third molars were used in this study because they were not previously exposed to any enviromental conditions.

Dental methods can be used to estimate age. There is a wide range of such methods. The oldest dental method of age esti-mation in adults was described by Gustafson in 1950 (1, 2, 3, 4). This is the first method that proposed using statistical methods in cal-culating age on the basis of teeth. In 1994 and 1995, Kvaal and Sol-heim worked on using dental ra-diography to estimate age. These non-sectioned or non-destruc-tive methods of age estimation are highly regarded in archaeological studies and in identifying living persons where we cannot afford to “sacrifice” a tooth (5, 6, 7). The main focus of method proposed by Kvaal and Solheim is on regres -sive changes that are visible on ra -diographs. For example, deposi-tion of secondary dentin results in decrees of pulp cavity. Measuring the dimensions of the pulp cavity on radiographs can indirectly give an estimate of the quantity of sec-ondary dentin (5, 6, 8). One ...

The sample for the study comprised 94 subjects with intact crowns of the first permanent maxillary molars, without orthodontic anomalies. Mesiodistal and buccopalatal diameters were measured on the plaster models, based on calculated variables: robustness index or crown area (IRC) and sexual dimorphism (SD). Linear dimensions of the first permanent maxillary molars, as well as the IRC exhibited sexual dimorphism with larger values in males, except MD diameter on the left side. The greatest sexual dimorphism demonstrates IRC from the right. Linear dimensions of the first permanent maxillary molars and IRC can be used for sex determination in population of Central Bosnia.

The aim of the research was to find out the most common dental anomalies in this particular group. The participants were 268 students at the Faculty of Dentistry. The examined students came from different regions of Bosnia and Herzegovina. The students were examined by the dentists employed at the Faculty while the findings were recorded on charts created specifically for this purpose and in accordance with the recommendations of WHO (World Health Organization). The students’ age ranged from 18 to 23. The results were statistically analyzed, and compared with the relevant facts from the literature. Our conclusion is that the most prevalent dental anomalies pertain to the teeth position (54%) followed by the teeth crowding at ICS (intercanine segment) (50%). The most negligible changes were found in the tooth shape, and this could b...

Identification of specific etiological factors NCCL is a key in making decisions about treatment. The authors conducted a study to evaluate the prevalence and distribution of noncarious cervical lesions in adults. Material and Methods: The sample of 210 respondents, were divided into three age groups. Clinical inspection has determined the distribution of NCCL within the respondents in relation to their age, teeth groups, vestibular and oral surfaces of the teeth, sides of the jaws and expression of NCCL according to the tooth wear Smith– Knight Index. Results: This research points to a very common finding NCCL within our respondents. Cervical lesions were diagnosed in 78.6% respondents in the first, 91.4% in the second and 97.2% in the third group. It has been shown that the number and expression o...
