Impact of Anxiety on Health-Related Quality of Life and Symptoms of Burnout in Multi-Professional Residents in Brazil During the COVID-19 Pandemic.

We aimed to determine the prevalence of anxiety and to identify associated factors among multi-professional residents in Brazil during the early days of the COVID-19 pandemic. A cross-sectional study included a sample of 752 multi-professional residents selected by snowball technique. Symptoms of anxiety were measured by the Beck anxiety inventory scale (≥ 16 cut-off).

Evaluation of the Association of Early Implant Failure With Local, Environmental, and Systemic Factors: A Retrospective Study.

Purpose: This study aimed to assess the association of early implant failure (EIF) with demographic, local, environmental, and systemic factors.

Methods: Clinical charts of 594 individuals with 2,537 dental implants were assessed. EIF was characterized by implant loss before and up to the abutment connection.

Peripheral dentinogenic ghost cell tumor-report of two cases and review of the literature.

Peripheral dentinogenic ghost cell tumor (DGCT) is a rare and non-aggressive benign odontogenic tumor. They usually affect the elderly and are predominantly located in the anterior region of the jaws. Their differential diagnosis includes reactive/inflammatory gingival lesions.

Systemic risk indicators for peri-implant diseases in individuals with implant-supported fixed prostheses: A cross-sectional study.

Purpose: The present study aimed to identify the systemic risk indicators associated with peri-implant mucositis and peri-implantitis in individuals with implant-supported fixed prostheses.

Materials And Methods: In this cross-sectional study, clinical evaluations of periodontal and peri-implant conditions were performed by a single examiner in a sample of 71 volunteers with 360 implants. Peri-implant mucositis was defined as the occurrence of bleeding on probing in association with redness and swelling or suppuration, without bone loss.

Central giant cell granuloma: A clinicopathological and immunohistochemical study of macrophages, blood vessels, lymphatic vessels and regulatory proteins.

Objective: This study seeks to investigate immunohistochemical parameters that could distinguish non-aggressive Central giant cell granuloma (CGCG) from aggressive CGCG, two groups of lesions which differ in their clinical and radiographic features and prognosis.

Material And Methods: 12 cases of non-aggressive CGCG and 11 cases of aggressive CGCG were investigated and associated the immunohistochemical expression of macrophages (CD68 and CD163), blood vessels (CD34 and CD105), lymphatic vessels (D2-40) and regulator proteins (p63 and Ki-67). Clinical and radiographic features were also studied.

Ameloblastoma with adenoid features: A series of eight cases.

Background: Ameloblastoma with adenoid features are characterized by the presence of duct-like structures formed from the parenchyma of the tumor. This study was conducted to report a series of eight ameloblastomas with adenoid features, highlighting their clinicopathological and immunohistochemical aspects.

Material And Methods: Out of 71 cases of ameloblastomas, this study classified 8 cases as ameloblastomas with adenoid features.

Influence of arthrocentesis irrigation volume at temporomandibular disorder treatment.

Introduction: Temporomandibular disorder (TMD) treatment varies from conservative therapy to invasive procedures such as arthrocentesis. The procedure is simple and has speed, low cost, low morbidity and good patient acceptance. Literature variations, however, have been found about the type and volume of the solution used for the irrigation of temporomandibular joint (TMJ).

Total bilateral TMJ reconstruction for pain and dysfunction: Case report.

Introduction: Temporomandibular disorders encompass a set of clinical conditions that affect the temporomandibular joint, the masticatory muscles and the associated tissues. Many therapeutic alternatives can be considered, being divided into non-invasive, minimally invasive and invasive interventions. This work aims to report a case of inflammatory joint pain and dysfunction treated with bilateral TMJ full reconstruction with alloplastic prosthesis stock.

Appositional bone graft tunneled: Technical note.

Introduction: A satisfactory positioning of the dental implants is very important in the cosmetic and functional outcome in this treatment for edentulous. Insertion of an endosseous implant in the correct positioning requires sufficient bone volume. Therefore, bone-grafting procedures are becoming increasingly common, especially for the augmentation of horizontally deficient ridges.

Epithelioid hemangioma in the oral mucosa – A case report.

Introduction: Epithelioid hemangioma is an uncommon benign vasoproliferative neoplasm that usually manifests as multiple red nodules in middle-aged adults

Case Outline: 52-year-old male patient presented with a one-year history of a nodular lesion in the left buccal mucosa measuring 3 cm. The clinical hypothesis was lipoma. An excisional biopsy revealed a circumscribed lesion composed of lobules of vessels with perceptible or poor lumina, associated with a prominent inflammatory infiltrate consisting of eosinophils, histiocytes and chronic inflammatory cells.

Transcriptional profiles of SHH pathway genes in keratocystic odontogenic tumor and ameloblastoma.

Background: Sonic hedgehog (SHH) pathway activation has been identified as a key factor in the development of many types of tumors, including odontogenic tumors. Our study examined the expression of genes in the SHH pathway to characterize their roles in the pathogenesis of keratocystic odontogenic tumors (KOT) and ameloblastomas (AB).

Methods: We quantified the expression of SHH, SMO, PTCH1, SUFU, GLI1, CCND1, and BCL2 genes by qPCR in a total of 23 KOT, 11 AB, and three non-neoplastic oral mucosa (NNM).

A comparative study of internal fixation and intermaxillary fixation on bone repair of mandibular fractures through radiographic subtraction.

Conventional radiographic evaluation of fracture healing is not a reliable method, because it depends on the examinator's experience and the quality of the exam. Therefore, serial images differing in density, contrast and geometrical projection can lead to a misdiagnosis on the postoperative fracture healing. Even in good quality images, little changes in calcified tissues often can't be visualized, because of its little sensibility and because of the limited human sight.

Oral findings in patients with mucolipidosis type III.

Mucolipidosis type III is a rare, autosomal recessive disorder, which is part of a group of storage diseases as a result of inborn error of lysosomal enzyme metabolism. It is characterized by the gradual onset of signs and symptoms affecting the physical and mental development as well as visual changes, heart, skeletal and joint. Although oral findings associated with mucolipidosis type II have been extensively reported, there is a shortage of information on mucolipidosis type III.

Keratocystic odontogenic tumour: an experience in the Northeast of Brazil.

Introduction: Keratocystic odontogenic tumours raise particular interest, because of their high recurrence rate and association with nevoid basal cell carcinoma syndrome.

Objective: To analyze the clinical and histopathological features of all cases diagnosed as keratocystic odontogenic tumour in a Brazilian population.

Methods: A total of 64 keratocystic odontogenic tumours, arising in forty-six patients, were evaluated using the following parameters: association with nevoid basal cell carcinoma syndrome, gender, age at first diagnosis, race, anatomical location, symptoms, radiographic features, history of recurrence, association with teeth, and treatment.

Gingival cyst of the adult: a case report and immunohistochemical investigation.

A 42-year-old woman had a sessile swelling that involved the maxillary gingiva corresponding to the right canine and premolar area. Clinical examination showed a painless small nodule (10 mm in diameter) located between the right maxillary canine and premolar. The lesion was vesicular, sessile, and slightly compressible on palpation.
