Patient?s perception of improvement after surgical assisted maxillary expansion (SAME) : pilot study

Objective: Clinicians often assume that changes following orthognathic surgery are both physically and psychologically beneficial to the patient. The present study investigates patient perception regarding improvement after surgically assisted rapid maxillary expansion. Study design: A survey with twenty-three patients was carried out to identify satisfaction with the surgical outcome and assess whether the surgery met patient expectations. General information was also collected on schooling, age, gender, chief complaint and reasons for seeking treatment. Results: Most patients (n = 19; 82%) were advised to undergo surgery by a dentist. Twenty-two (95%) patients reported being satisfied with the operation procedure. Twenty-one (91%) patients reported that the procedure met their expectations. Nineteen respondents would undergo the same operation again and would recommend treatment to others with similar problems. Conclusion: The need for surgery associated with orthodontic appliances to correct a transverse maxillary deficiency requires a proper explanation to patients regarding the procedure and postoperative period in order to ensure realistic expectations concerning the surgical goals

Simplification on the Reduction of Comminuted Mandibular Fractures for Stable Internal Fixation

Background: The fractures of the comminuted type have a prevalence of 30 to 50% when related to the ones affecting the mandibular bone. They are characterized by the presence of multiple bone fragments involving several lines of fracture, resulting in small fragments within the same area. Usually resulting from high-energy trauma, they cause large displacements, tooth loss, as well as associated lesions in soft tissues. Cases Reports: This study aimed to report two cases addressing the simplification method in the reduction of comminuted fractures treated by the method of open reduction and functionally stable fixation, which emphasized the importance of establishing a sequence of reduction maneuvers and application of osteosynthesis for a functional, occlusal and aesthetic result of the lower facial third. Conclusion: The simplification of mandibular comminuted fractures proves to be an excellent ally when one intends to reduce difficulties of reduction of the fracture and the dental occlusion on the transoperative, as well as to facilitate the application of 2.4 reconstruction plates

Ankylosis Due Sequel Of Fracture Of The Mandibular Condyle: Case Report

The Ankylosis of the Temporomandibular joint (TMJ) is a disorder of craniofacial complex that results in the merger between the condyle and the mandibular fossa, causing partial or complete immobilization of the mandible. The etiological factors are local and systemic inflammation, infection in the area of TMJ, rheumatic diseases and neoplasms, having the trauma as the main etiologic factor. The traumas are responsible for 31% to 98% of cases of ankylosis. The diagnosis is made from the anamnesis and imaging scans (computed tomography) pointing to the union of joint components. The treatment of ankylosis is a big challenge due the high rate of recurrence that can be affected by factors such as type of ankylosis, surgical technique, age of the patient, post-operative physiotherapy and systematic follow-up of the patient. The various forms of treatment require careful analysis of type of ankylosis if it is intra or extra-articular, unilateral or bilateral and if it is bony or fibrous, There is no consensus in current literature regarding the best treatment. The aim of this work is to present through the report of a clinical case, a surgical treatment of Unilateral Temporomandibular joint Ankylosis, due to sequel of condylar fracture with re-establishment of the stomatognathic functions in postoperative follow-up

Comparative Analysis of the Effectiveness of the Topical Administration of Benzocaine and EMLA® on Oral Pain and Tactile Sensitivity

Objectives. To compare the effectiveness of the topical administration of benzocaine and EMLA on oral pain and tactile sensitivity. Materials and Methods. A randomized, double-blind, split-mouth clinical trial was carried out with 20 volunteers. The sensorial and quantitative tests were applied before the contact with topical anesthetic and after the application. Results. In the superficial tactile perception test, when we compared each group singly, there were statistically significant values in the decrease of superficial tactile perception when compared to the moment prior to the application of anesthetic agents. For the sensitivity to mechanical pain, no statistical significant difference was observed at evaluated times. In the needle penetration test, in an intergroup analysis, we found a decrease in the pain sensitivity to needle penetration at 5 min (p=0.053) and at 10 min (p=0.019) after the contact of the anesthetic drug with the oral mucosa. Conclusion. The application of topical anesthetic drugs reduces the discomfort associated with this procedure, mainly until the first 10 minutes. Only the needle penetration sensitivity test showed sufficient sensitivity to reveal a difference in the anesthetic effect between EMLA and benzocaine. This trial is registered with RBR-2N2GSW

NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics

Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used. We also request that users inform us of how they intend to use the data
