Objective: To perform a systematic review on the effects of listening to music in reducing preoperative anxiety and pain (intra or postoperative) in third molar extractions. Material and methods: A systematic review modeled according to the PRISMA guidelines was conducted. The MEDLINE/PubMed, Cochrane Library, Embase, and Scopus databases were searched for relevant reports. To be included in the study sample, the studies were required to be randomized controlled trials (RCT) on the effects of listening to music on outcomes of third molar extraction. Two reviewers independently extracted the relevant data from the reports. Results: A total of 1882 studies were retrieved after the duplicates were removed. After applying the inclusion criteria, five studies were included for qualitative analysis. In 4 studies, music was played before and during the extraction of the impacted third molars. In one study, music was played only before the procedure. The genres varied from classic piano music to rock, pop, jazz, folk, and even hymns. Overall, music listening was beneficial for patients in reducing preoperative anxiety or anxiety during the procedure compared to control. However, only one study demonstrated a statistically significant decrease in systolic blood pressure. Conclusions: Music may be an effective non-pharmacological measure to reduce preoperative anxiety in patients scheduled for third molar extraction; however, the hemodynamic effects and the effects on pain (both perioperative and postoperative) should be further explored. Clinical relevance: The side effects of certain medications may be avoided if listening to music is used in third molar extractions.

Raynaud’s Syndrome (RS) is generally characterized by either ischemic or hyperemic symptoms and is relatively frequent in patients hypersensitive to cold or with emotional stress. This phenomenon usually cease after no more than some minutes, however, can persist for hours Its treatment is aimed at promoting vasodilation i.e., warming procedures. Anxiety control prior to surgical procedure helps in prevention the occurrence of RS. Despite RS following local dental anesthesia being rare, dentists must be prepared to manage. There are limited reports of patients with this syndrome during dental procedures, so here we describe a case of a patient who has undergone a surgical implant installation and who developed primary RS following local anesthesia using an adrenergic vasoconstrictor, as well as the management of this complication in dental office. Dentists should be able to recognize the RS and follow the appropriate guidelines available, after control the case the patient should also be referred to a general physician for further investigations.

Complete removal of hypertrophied inferior nasal turbinates may favour the occurrence of the empty nose syndrome (ENS). Some surgeons recommend partial turbinectomy in order to minimize the occurrence of ENS. However, little is known about whether total removal of the inferior nasal turbinate is associated with ENS. The aim of the present study was to evaluate the effects of total turbinectomy and septoplasty on the breathing of individuals undergoing orthognathic surgery with maxillary impaction. A total of 20 individuals participated in this cross-sectional study, in which the relationship between exposure (maxillary orthognathic surgery) and outcome (nasal respiratory function) was investigated. The Empty Nose Syndrome 6-Item questionnaire and Nasal Obstruction Symptom evaluation scale were applied to investigate the ENS. A three-dimensional assessment of the piriform opening was performed pre- and postoperatively by computed tomography in order to measure the volume of the nasal cavities using the Dolphin Imaging software. ENS was detected in 35% of patients, while 13 reported improved breathing. Symptoms of ENS such as dryness, suffocation, nose feels too open and nasal crusting were mentioned. The mean nasal cavity volume was 7477.15 mm³ greater in the initial evaluation (p<0.05). In summary, the occurrence of ENS does not constitute an absolute contraindication of total turbinectomy, a procedure that contributed to the improvement of airway permeability.

Propouse: surgical teams sometimes neglect surgical glove perforation. The aim of this study was to determine the prevalence of sterile glove perforation in maxillofacial surgical procedures. Methods: Two studies were performed. The first one evaluated 200 pairs of surgical gloves (50 in each group) used by first, second, and third-year residents (R1,R2,R3). In the second study, 150 pairs of surgical gloves were evaluated: 100 pairs were used by a third-year resident, including 50 pairs in oral surgery procedures and 50 pairs in trauma surgeries, and 50 pairs of unused gloves were tested as control. The gloves were examined for perforations by filling them with water and testing for leaks. Results: In the first study, 29 pairs (19.3%) were perforated. Of the 50 pairs of control gloves, 7 pairs (14%) showed perforations on either side. The thumb and index finger and the right-hand (dominant hand) gloves, were the most frequently perforated sites. In the second study, 6% of the gloves in the control group, 6% of the gloves used in oral surgeries, and 10% of the gloves used in trauma surgeries showed perforations. The index finger and thumb were the most affected sites. Conclusion: The perforation rate was higher for the dominant right hand. In both studies, the frequency of perforation of unused gloves was significant, indicating the need for better quality control of the gloves evaluated in this study.

It know that currently in the routine of dental offices the frequency of patients who use antithrombotic medications such as anticoagulants and antiplatelet agents is quite relevant, these drugs act to decrease blood coagulability, preventing thromboembolic problems from occurring. And with that it brings the diversity of thoughts in relation to performing dental surgical procedures. With the evolution of dentistry, it is possible to observe the diversity of existing protocols for the care of these patients, ranging from the change of heparin, reduction or pause of antithrombotic medication, to its maintenance, emphasizing the use of local hemostatic techniques. In view of the use of antithrombotic therapy by these individuals who started to make constant dental consultations, the purpose of this study was to analyze the most appropriate way to perform the care of these patients who are subjected to oral surgical procedures. The INR test is a calculation performed between the prothrombin time and the average of the normal coagulation interval, where it demonstrates that it is reliable to perform dental surgery if the INR is between 2 and 3.5. If it is higher than 5, it is not recommended to perform any procedure. Some authors claim that it is reliable to perform dental surgeries without major bleeding and in a safe manner, as long as the International Standardized List (INR) is included in the therapeutic levels. In this perspective, it was possible to analyze that maintenance on anticoagulant therapy, associated with the use of local hemostasis methods, represents the most appropriate protocol for surgical cases at an outpatient level.     

Ludwig's angina, considered a medical emergency, is an infection that affects the submandibular, sublingual, and submental spaces, presenting a course of rapid and potentially fatal evolution. The purpose of this report is to describe the treatment of a case of Ludwing's Angina, due to dental infection, associated with cervicofacial and mediastinal complications. The female patient appeared with a history of increased volume in the region in the bilateral and submental submandibular region, complaints of dysphagia, and dyspnea, in addition to trismus. The patient was initially treated employing drainage and extraction of the element that caused the infection, 72 hours after the operation, however, the patient returned to dyspnea. For the treatment of this complication, there was the option to perform cervicotomy associated with broad-spectrum antibiotic therapy. The therapeutic approach containing airway maintenance, cervicotomy, antibiotic therapy, as well as the removal of the etiological factor was effective for the management of this case of Ludwing's angina complication.

Dentofacial deformity is described as a condition in which the jaw bones are out of normal, where malocclusion exists and facial aesthetics are affected. This condition affects about 20% of the world population and requires an accurate diagnosis. Orthognathic surgery in combination with orthodontic treatment is the treatment of choice for the correction of dentofacial deformities, due to its high complexity, a multidisciplinary approach is necessary to perform such treatment. This paper aims to discuss the diagnosis and treatment of dentofacial deformities through a literature review and presentation of a clinical case. In the case reported, the patient with class III dentofacial deformity underwent orthodontic treatment and orthognathic surgery planned virtually using the Dolphin 3D software. After the surgical procedure, a significant improvement in facial harmony and occlusal stability was observed. Such results are maintained in a two-year postoperative follow-up. Virtual planning in orthognathic surgery is becoming increasingly important, allowing surgeons to simulate multiple options of jaw movements until the best results are obtained for the patient.
