This paper consists in the evaluation of the exposure rate to ionizing radiation to which professionals working in surgical procedures which require radiological examinations are subjected. Were initially performed real-time readings of exposure rate within four distinct operating rooms during the execution of four surgical procedures that made use of fluoroscopy equipment (including three orthopedic surgeries, one in the shoulder, one in the arm, another for deployment of metal pin in the leg region, and a fourth for vascular procedure); in these surgeries were used ionization chamber detector and an electrometer. In order to check the values achieved, was made a re-evaluation of the distribution of the rate of exposure to radiation, from the surgical procedures, now with thermoluminescent dosimeters (TLDs). For this, thirty TLDs were distributed in the operating rooms, arranged in points of interest as occupation by professionals. The TLDs were prepared for thirty consecutive days, after which they were removed and replaced with new dosimeters not exposed yet. The dosimeters were subjected to reading of the rate of exposure; this procedure was repeated for four months without interruption. The quantification of the results sought primarily to convert the rate of exposure for equivalent dose rate, both in measurements with ionization chamber as in measurements with TLDs, in order to highlight the presence of the biological effect of ionizing radiation for comparisons within scientific context. Then, the results were plotted to establish the relationship between the values of equivalent dose and the distance to the central axis of the x -ray source, confirming the inverse square law for distance. Finally, the values were associated with the maximum limit recommended by the legislation for occupationally exposed individuals. The methodology for the analysis and quantification of the data in this work aims at implementing a work plan that meets ...

We aim to contribute to studies on the restructuring of the city with a focus on consumption. In the context where cities become the main place of action of man, a deep set of transformations has occurred. We are interested in understanding the redefinition of the logical production and appropriation of urban spaces for consumption of materials and services. For the analysis of delimitation of those commercial and service areas was made to compare the reality observed on the ground and indirectly through data acquisition and mapping obtained from the National Address List for Statistical Purposes, with the boundaries established by zoning and / or by municipal director plans of the cities studied, together with the classification of commercial establishments and in accordance with the standards of the National Classification of Economic Activities Services. We believe the importance of analyzing the process of concentration and dispersion of stores and / or services of Londrina (PR), Presidente Prudente (SP) and Ribeirão Preto (SP)...

Several aspects beyond the restorative phase itself such as orthodontic movement and periodontal treatment must be considered in cases of closure of diastemas. In such cases, a multidisciplinary approach is essential. As patients during orthodontic treatment may show high risk of developing dental caries and periodontal disease, inflammation of the gingival tissue is a common finding. For this reason, a preliminary basic periodontal treatment is critical to the success of restorative procedure. In addition, postoperative care and instruction in phonetics, oral hygiene and periodic control must be considered by professionals and patients. Thus, this paper demonstrates through a case report, pre and postoperative issues that should be considered during the closure of diastemas using a layering technique with resin composites

The increasing interest of patients for a better aesthetic appearance of their smile, associated with the development of new materials and techniques, encouraged by media couverage of this concept of beauty, provided an important evolution of cosmetic dentistry. As the darkness of a single anterior tooth or a group of teeth, in most cases, impairs the appearance of the smile and there is growing appreciation of the less invasive procedures, the technique of tooth bleaching is an important option for aesthetic treatment. To have success in the bleaching treatment, it is important to have knowledge of the origin, nature and composition of the stain. Among the causes of color changes acquired post-eruptive, dental trauma, with or without pulp necrosis, is one of the most commonly encountered etiologies, characterized by a reddish-brown color. Current techniques of bleaching for teeth treated endodontically employ oxidative agent hydrogen peroxide. The objective of this paper is to describe the immediate technique of bleaching non-vital tooth by presenting a clinical case.

Tooth bleaching is a treatment modality that raises great interest, due to the important role played by aesthetics in current life style. To perform such procedure, nowadays, there are several bleaching substances at several concentrations, as well as, diverse clinical techniques. When suggesting this procedure, the dentist should take into consideration several factors related to the patient to determine which will be the most appropriate technique/material combination for solving the clinical problem. The procedure indication should not only be based on the expectations exhibited by the patient, but also on respecting the biological principles to maintain the integrity of both the endodontic and periodontal tissues.

Objective: This study aimed at evaluating the difficulties reported by last-year dentistry course students regarding basic and surgical periodontal procedures. Methods: A proposed questionnaire with 24 questions, 14 related to basic periodontal procedures and 10 to surgical procedures, was applied to 45 undergraduate students with jobs involving these procedures, during the practical activities of the Integrated Clinic Discipline, a compulsory subject in the curriculum of the course, taught to last-year students. Students were asked about their own perceptions of the difficulties in implementing the various steps related to the treatments. The degree of individual difficulty was determined according to the Likert scale: 0 = none, 1 = mild, 2 = moderate, 3 = high, 4 = very high. Exploratory analysis of data was applied, and the difficulty level was also dichotomized into none to mild (scores 0 and 1) and moderate to very high (scores 2–4). Results: Regarding the basic periodontal treatment, bone level probing was the procedure with the highest number of student difficulties (57.5%). As for the difficulties reported by students regarding the stages of periodontal surgery, only the procedures related to anesthesia and suture removal had no report of doubts. Conclusion: Periodontal surgery was the procedure involving the most prevalent questions reported as moderate to very high, and the indication for the most suitable surgical technique was the stage with the highest percentage of questions (66.6%) among the undergraduates.

Introduction: Despite tooth avulsion following trauma being relatively common in children, the available studies show that adults have limited knowledge about it. Aim: The purpose of this study was to assess, by a questionnaire, the mothers’ general knowledge about the immediate management of tooth avulsion. Material and method: This descriptive study was carried out on a convenient sample of mothers (n= 65) who participated of the “Pastoral da Criança”, from Araraquara, SP, Brazil. The questionnaire comprised 15 questions about personal data and knowledge on tooth avulsion management. Results: Participants were, on average, 35 years old. A total of 30.8% of the mothers reported that their children suffered dental trauma. The majority had never received advice on this subject (76.9%); and did not know how teeth are kept in the dental arch (69.2%). Almost a half of the sample believed that an avulsed tooth can be replanted (49.2%). In relation to the management of tooth avulsion, 40% of them would clean the avulsed tooth with water, even if it was not dirty (38.5%). Most of them (69.2%) would take the tooth by hand for cleaning purposes, regardless the tooth region; and believed that brushing the tooth was important to take the dirty out (67.7%). Conclusion: The general knowledge of mothers about the immediate management of tooth avulsion was considered inadequate endangering the successful treatment of tooth avulsion.

This study based on moral culture research and the theoretical Piagetian perspective aims to investigate the relation between virtue and rules in the procedures of participants in the Internet game Colheita Feliz (Happy Harvest) – an Orkut application. By means of descriptive qualitative analysis, the behavior of 60 participants in the game was observed during two months. The participants’ performance ranking was analyzed according to the procedures they used. The results showed predominance of the crop stealing procedure in comparison with the crop cultivation procedure and allowed to consider that the action of stealing of the participants was not guided by the universal principles of virtue, honesty or lack of it (moral domain) but by the playing convention for the game (social domain) favoring the stealing procedure, and also by personal domain (choices) and mutual agreement among the subjects participating in the game. The data did not indicate connections between the participants’ actions inside and outside virtual and real fields with regard to stealing, and reinforced the idea that rules are conventionalized in the domain of a group and depend on social interactions by which mutual respect among peers must prevail. The data also shows that morality is not the regulatory actions in the game. The results also showed the importance of carrying out research on procedures used by computer game players since such procedures can demonstrate cognitive, moral, affective and social aspects perceived during playful interaction situations.
