A prática de medicina, a organização dos serviços de saúde e o início do ensino médico no Estado do Pará são apresentados em uma perspectiva cronológica desde os primeiros relatos, após a chegada de Francisco Caldeira Castelo Branco, em 1616, até a fundação da Faculdade de Medicina e Cirurgia do Pará, em 1919. Alguns fatos históricos são destacados e contextualizados, assim como mencionados determinados personagens que tiveram participação efetiva nos acontecimentos relatados. Também são comentados aspectos relacionados ao ensino médico, tanto no âmbito nacional quanto no Estado do Pará, e sua importância para a Região Amazônica e parte do nordeste brasileiro.

Introduction and Objective: Microorganisms are responsible for multiple infections and pathologies; this is why it is important to control microbes that can be found in the triple syringe used for irrigation in different dental procedures. The aim of this study was to identify cultivable species of microbes (fungus and bacteria) found in some dental units water lines of a private dental clinic from Medellín, Colombia. Materials and Methods: Random samples were taken from 11 chairs from a total of 89; a sample of water of 500ml was collected from the triple syringe of each selected chair. The study aim to search for the presence of total coliforms, filamentous fungi and leavened Results: the average presence of microorganisms was between 40CFU and more of 200 CFU. Microorganisms such as Aeromona salmonicida, Actinobacilus sp and Pseudomona maltophil were isolated. No total coliforms neither fecal coliforms were found. Conclusions: the high levels of contamination suggest that there is a mature biofilm in somewhere of the dental unit water line, but the absence of total and fecalis coliforms suggest that the water had been treated.

To evaluate changes in microhardness, roughness and surface morphology of dental enamel and composite resin after different tooth bleaching techniques. Material and Methods: Dental fragments from bovine incisors with composite resin restorations were submitted to different bleaching protocols: G1 – daily 8 hours application of a 10% carbamide peroxide (CP) gel during 21 days; G2: 3 applications of 15 minutes of a 38% hydrogen peroxide (H2O2) gel; G3: 38% H2O2 gel associated to irradiation with LED (470nm) during 6 minutes. The Knoop micro hardness of enamel and composite resin were evaluated at 1, 7, 14 and 21 days for G1, and after 1, 2 and 3 sessions for G2 and G3. The roughness and superficial morphology (atomic force microscopy) were evaluated before and at the end of the bleaching treatment. The data were analyzed by Mann-Whitney and Wilcoxon tests (=5%). Results: Significant reduction on enamel hardness was observed after 2 and 3 sessions for G2 and G3. For composite, the reduction occurred after 21 days for G1, and after 3 sessions for G2 and G3 (p<0.05). Significant reduction on roughness and superficial morphology were observed only for enamel of G1 group (p<0.05). Conclusion: The 10% CP gel promoted only superficial alterations on dental enamel, while the 38% H2O2 gel promoted mineral reduction of this dental tissue. All the bleaching protocols promoted reduction on hardness of composite resin.

The condylar hyperplasia is an acquired development anomaly, rare, characterized by an excessive and progressive growing, affecting neck, condilar head, body and the mandible bough, provoking an important facial asymmetry. In the article we present a case of male patient, 22-years-old, reclaiming of painful sintomatology in the region of temporomandibular joint and severe facial asymmetry. It was instituted an orthodontic-surgical treatment by means of orthognathic combined surgery and high condilectomy. After six years of post-surgical controlling, the patient is now in a good shape, without recurrence of facial asymmetry and condylar hyperplasia.

The aim of this study was to evaluate the local anesthetic solution, composed by Prilocaine 3% and felipressin 0,03 UI/ml, influence on the alveolar repair process in rats after dental extraction. This research was previously approved by the Ethic Committee in Research of the Masters Degree Program in Oral and Maxillofacial Surgery of the Marília University (UNIMAR), Marília, São Paulo, Brazil. It was an experimental, randomly controlled study, with bifactorial analysis (group control versus experimental group, in function of the postoperative times (2 X 4)). For the accomplishment of this study 32 rats were used (Rattus norvegicus, albinus, Wistar), males, adults, weighing between 280 and 320 grams. The animals were selected and divided into Group I (control) and Group II (Citocain 3%® - Prilocaine 3% with felipressin 0,03UI/ml) with 16 rats each; being four animals of the Group I and four of the Group II, destined to the euthanasia in the postoperative periods of 3rd, 7th, 15th and 24th days. The histological analysis with base in the developed methodology, allowed us to conclude that the anesthetic solution of Citocain 3%® applied with gauze compress on the surgical dental wound, produced tissue events that committed the basic biological principles, that are responsible for the regeneration of the gingival epithelium and the alveolar process repair in rats. The Group I presented better results in the alveolar repair when compared to the Group II.

The aim of this study was to evaluate the correlation of color change on bleaching tooth through delta E (ΔE) by the spectrophotometer Spectroshade (SS) and digital program Scanwhite (SW). Methods: 25 patient volunteers were recruited from Operative Dentistry at Universidad de Chile Dental School, between 18 to 30 years, with good oral hygiene. Exclusion criteria: Previous experienced tooth bleaching, anterior restorations, cervical lesions, pain dental, pregnant patient, stained teeth, malposition of the teeth and periodontal pathology. The bleaching was made in two sessions with three different bleaching systems which were randomly. The assessment of color change through ΔE was made on the two upper central incisors (N=50) by the SS and SW. The color in the same teeth were measured before (T0) and after (T1) of the bleaching treatment. Data were analyzed using test Spearman correlation coefficient (Rho) with a significant level of 95%. Results: The results showed a positive and significant correlation (0.676), with a statistically significant difference (p<0.05). Conclusion: There is correlation in the measurement of color change on bleaching tooth by SS and SW.
