title: Cranioplasty using Polymethylmethacrylate (PMMA) self-curing by the conventional casting process: clinical case report

description: ABSTRACT Cranioencephalic trauma which results in extensive edema and / or bruising usually requires surgical treatment through a greater withdrawal of the bone portion. Thus, the absence of bone tissue implies the lack of protection of the brain tissue or even compromises the esthetics especially when located in the frontal or frontoparietal region. The purpose of this case report is to describe a treatment option for head trauma, through the prefabricated part by obtaining the skull model. These bone faults can be reconstructed either by the direct method using polymethylmethacrylate directly on the defects or by means of pre-made pieces such as prototyping or from the skull model. Although other techniques have many good points, some show certain drawbacks, from storage conditions below abdominal fat, preheating due to the release of heat during the high polymerization reaction or the high cost when they are prototyped. The technique described in this work reports its simple performance, eliminating the risk of local heating, allows prior sterilization in autoclave, it is biocompatible, allows perfect anatomical recovery, easy placement, low cost, also highlighs the advantage of the bucomaxillofacial surgeon's performance due to the familiarization with the relevant head and neck procedures. Clinical and tomographic examination after 24 months of treatment showed stability of the polymethylmethacrylate plate, adhesions to the bone margins, and absence of tissue alterations.

title: Ewing’s Sarcoma: imaging findings of a patient with primary tumor in the femur and mandibular metastasis

description: ABSTRACT Ewing’s Sarcoma, a common primary bone malignancy that usually occurs in childhood and young adults, has a predilection for males and occurs mostly in the diaphysis of long bones and pelvis. This tumor rarely affects the head and neck. Histologically, this neoplasm is a small round cell tumor and there is evidence of a neuroectodermal origin. Radiographic findings of ES show an osteolytic lesion, that is not a pathognomonic feature for this neoplasm. The association of conventional imaging methods such radiography, Computed Tomograph (CT), magnetic resonance imaging (MRI), combined with scintigraphy or Positron Emission Tomography/ Computed tomography PET /CT), is essential for a correct diagnosis and treatment. Therefore, the aim of this report was to present image findings of a patient who presented with ES in the femur, and a metastasis in the mandible after eighteen months, and discuss the importance of imaging methods for a correct diagnosis, treatment and consequently, prognosis.

title: Complications associated with the bichectomy surgery

description: ABSTRACT This research study aimed at reviewing, in the literature, the aspects related to the buccal fat pad structure, named the Bichat Ball, evaluating the anatomy of the area, the buccal fat pad clinical applications and the possible complications of its surgical removal, as well as reporting a series of cases that presented such complications. The most important anatomical structures surrounding the buccal fat pad and that are frequently involved in surgical complications are the parotid gland duct, the facial nerve branches, the blood vessels and the muscular tissues. In Dentistry, the buccal fat pad clinical application has an aesthetic purpose and it can be removed or repositioned. The removal occurs to avoid intra-oral trauma, "nibbling", and the pedicle repositioning occurs for protection or to be used as a graft. The complications of the surgical removal of the buccal fat pad are not frequent, however, hematoma, infection, facial nerve and facial vessel injuries may occur. Therapies involved in it include drug therapy, drainage, laser therapy and compresses.

title: Dental self-perception and clinical dental description of participants in the Open University programme for elderly people

description: ABSTRACT Objective: This study verified both the self-perception and oral characteristics of a group of elderly participants of the Open University for the Elderly (UNATI). Methods: The sample consisted of a cross-sectional epidemiological study with elderly subjects (50 years of age or older), who attended the UNATI-UNIFAL/MG program. Data collection was carried out using a semi-structured questionnaire consisting of open- and closed-ended questions regarding oral health, its interference with self-esteem and nutrition, among other features. In addition, an application form based on the proposals by the Oral Health Survey 2010, was used. Univariate and multivariate descriptive analyses were performed. Results: The study sample consisted of 106 subjects (mean age of 62.4 years), of whom 59.4% had attended a dental appointment in the last year for routine and/or aesthetic examinations (38.7%). The clinical conditions showed that only 19.8% of the subjects were completely edentulous, an average DMFT of 26.1, and 37.7% used some kind of complete upper dentures, complete lower dentures, or both. Regarding self-perception of oral conditions, 34.9% considered it a regular perception, however in the applied statistics the presence of pain demonstrated a worse perception which was not correlated with teeth loss, presence of dentures and/or restored teeth. Conclusion: The self-perception of oral conditions is regular and the clinical and odontological characteristics evaluated revealed partial edentulous subjects with high DMFT. By evaluating the odontological aspects, it was observed that the majority of the subjects did not have difficulties to look for a dentist, they attended dental appointments in the last year and the preventive treatment had been the most required.

title: Effect of an hydrophobic layer on a universal adhesive

description: ABSTRACT Objective: evaluate bond strength of a universal adhesive, associated to an extra hydrophobic sealing layer, and compare after three and six months immersed in distilled water. Methods: After ethical approval of the CEP / HUUFMA, 12 human third molars (n = 6) were extracted, which were divided into two groups: SB - control group - selfetching; and SBHidrof - selfetching group associated to the hydrophobic layer (Adhesive layer, 3m ESPE). After incremental restoration with composite resin (Opalis, FGM), the teeth were sliced to obtain specimens (1mm2) and then submitted to the universal test machine (INSTRON 1mm / min.), immediate and after three and six months. The data were submitted to normality (Shapiro Wilk), and comparative Analysis of variance (two ways: technique and time) and Tukey (p &lt;0.05). Results Immediate values showed no statistically significant difference (p&gt; 0.05), but after three and six months of immersion of the specimens, in distilled water, bond strength values were maintained in the group that received the hydrophobic layer (p&lt;0.05). Conclusion: It was observed that, by incorporating a hydrophobic layer on a universal adhesive system, it was possible to preserve dentin adhesion.

title: Image-based study of marginal bone loss in teeth restored with cast endodontic posts

description: ABSTRACT The aim of this study was to assess marginal bone loss in teeth restored with endodontic posts on all four aspects of the teeth using cone beam tomography. Bone loss was assessed via scores (0-5) in relation to root length and bone height. The results showed that the scores for the contralateral and restored sides, respectively, ranged from 0 to 3 and 0 to 5 buccally, 0 to 4 and 0 to 4 palatally, 0 to 3 and 0 and 4 mesially and 0 to 3 and 0 to 4 distally. A significant difference in bone loss was observed between the post-restored teeth and their contralaterals for the buccal, lingual/palatal and mesial aspects (p&lt;0.05), with teeth bearing endodontic posts scoring highest. In conclusion, marginal bone loss was higher in teeth restored with intra-canal posts when compared to their sound contralaterals.

title: West Syndrome: Report of Clinical Case: 9 Years of Follow-up

description: ABSTRACT West Syndrome is one of the rare and severe childhood epilepsies, starting in the first year of life and having an uncertain etiology. Even if some of the symptoms are missing, a triad of them defines West Syndrome, including epileptic spasms, arrest or regression of psychomotor development, and hypsarrhythmia on interictal electroencephalography. The objective of this study was to obtain updated data on West Syndrome literature and report a clinical case of a patient with the medical diagnosis of this syndrome, with gastrostomy feed tube, and clinical pattern of spastic quadriplegia. Initial clinical examination showed prolonged retention of deciduous teeth, periodontal disease, poor oral hygiene, mouth breathing, deep palate, anterior open bite, tongue interposition between the dental arches, and low caries experience. Over 9 years the patient presented complications in their sistemicas conditions, with need for gastrostomy and many periods of hospitalization that determined periods of absence for the dental monitoring. Despite this, currently his oral health condition is good and stable. Dental care for people with disabilities should be developed, encouraged and continuously extended, in agreement with the constitutional principles of human dignity and the rights for health and equality.

title: Buccal bifurcation cyst as an incidental finding in cone beam computed tomography scans

description: ABSTRACT Buccal bifurcation cyst is an unusual inflammatory odontogenic cyst of unknown etiology which occurs at the buccal region of the permanent mandibular first molars in children and adolescents aged 6-15 years old. The aim of this manuscript is to present two clinical cases of buccal bifurcation cyst incidentally detected in adolescents referred for tomographic exams (CBCT) as part of the treatment planning for the management of impacted mandibular molars. The first case is very interesting due to the proximity of the lesion to the inferior alveolar canal. In the second case the inferior alveolar canal was not in close proximity to the lesion, but in contact with the mesiobuccal root of the second molar. The diagnosis of Buccal bifurcation cyst is of utmost importance in order to avoid complications during surgical procedures. In addition, the present case reports have highlighted the importance for dental practitioners to be aware of the possibility of a buccal bifurcation cyst being present as an incidental finding in CBCT images, especially in young patients.
