RESUMEN
Odontogenic Keratocyst (OKC) is an aggressive cystic lesion of the jaws and one of the most common odontogenic cysts, usually affecting the posterior region of the mandible. Recurrences are frequently recorded and may be directly related to the treatment modality adopted. Two patients presenting OKC were treated by combining decompression and intralesional irrigation with the drug Elixir Sanativo® for 8 months before enucleation surgery. In both patients, the association between decompression and irrigation with Elixir Sanativo® represented a safe and effective method to reduce the preoperative lesion dimensions.
El queratoquiste odontogénico (QO) es una lesión quística agresiva de la mandíbula y es uno de los quistes odontogénicos más frecuentes, que suele afectar a la región posterior de la mandíbula. Las recidivas se registran con frecuencia y pueden estar directamente relacionadas con la modalidad de tratamiento adoptada. Presentación del caso: Dos pacientes que presentaban OKC fueron tratados combinando descompresión e irrigación intralesional con el fármaco Elixir Sanativo® durante 8 meses antes de la cirugía de enucleación. En ambos pacientes, la asociación entre descompresión e irrigación con Elixir Sanativo® representó un método seguro y eficaz para reducir las dimensiones de la lesión preoperatoria.
RESUMEN
Iatrogenic mandible fractures are rare complications from third molar removal surgeries. While most documented cases stress risk factors inherent to the patient and tooth presentation in fractures' etiology, appreciation of the risk factors underlying the practitioner's skills is scarce. Here, we describe an intraoperative fracture in a healthy 26-year-old female resulting from an incompatible surgical technique during the right mandibular third molar removal. The patient showed facial swelling, pain, malocclusion, and significant mobility of the fractured segment. The surgical management involved an intraoral open reduction with the installation of titanium plates for the fixation of the bone segments. Thus, we highlight that acknowledging the extent of the operator's surgical skills should be part of comprehensive treatment planning, serving as a valuable measure to prevent iatrogenic mandible fractures besides avoiding a traumatic experience for the patient.
RESUMEN
This two-arm, parallel-group, double-blind, randomized clinical trial design evaluated the risk of postoperative bleeding in anticoagulated patients undergoing dental extraction treated with topical TXA in comparison to collagen-gelatin sponge. Forty patients were randomly included in one of the study groups: (1) topical use of 4.8% TXA solution; and (2) resorbable hydrolyzed collagen-gelatin sponge applied to the surgical alveolus. Primary outcomes were postoperative bleeding episodes and secondary outcomes were thromboembolic events and postoperative INR values. The relative risk (RR), the absolute risk reduction (RAR) and the number needed to treat (NNT) were used as effect estimates and calculated from the counting of bleeding episodes observed during the first postoperative week. The bleeding rate under the TXA treatment was 22.2%, while in the collagen-gelatin sponge group it was 45.7%, resulting in a RR of 0.49 (95% CI 0.24-099; p = 0.046), RAR 23.5% and NNT 4.3. TXA was more effective in reducing bleeding in surgical sites located in the mandible (RR = 0.10; 95% CI 0.01-0.71; p = 0.021) and the posterior region (RR = 0.39; 95% CI 0.18-0.84; p = 0.016). Within the limitations of the study it seems that topical TXA is more effective in controlling bleeding after tooth extractions in anticoagulated patients than collagen-gelatin sponge. CLINICAL TRIAL REGISTRATION: RBR-83qw93.

RESUMEN
RESUMO Introdução: A lesão central de células gigantes é própria dos ossos gnáticos, sendo um tumor benigno não odontogênico. É uma lesão de crescimento predominantemente lento, bem circunscrito e assintomático, geralmente diagnosticada através de algum exame de rotina ou, em casos mais avançados, quando se começa a visualizar alguma alteração estético-anatômica ou através da queixa do paciente de algum desconforto localizado na região. Objetivo: Ilustrar um caso clínico de lesão central de células gigantes e sua resolução envolvendo momento cirúrgico e reabordagem que inclui a homeopatia na proposta terapêutica. Apresentação do caso: Paciente do sexo feminino, inicialmente com 4 anos de idade com uma lesão na região de pré-maxila. Após avaliação radiográfica, tomográfica, exames sanguíneos e biópsia incisional, foi realizada, em primeiro momento, a exérese da lesão sob anestesia geral, por curetagem com aplicação de solução de carnoy. Após proservação e surgimento de imagem radiopaca nos exames, deu-se início ao tratamento não invasivo com homeopatia e injeções de corticoide visando à redução e neoformação óssea em área sugestiva de tecido cicatricial. Conclusões: Abordagens mais conservadoras podem ser, em muitos casos, uma opção plausível que acaba por livrar o paciente de cirurgias mutilantes(AU)

ABSTRACT Introduction: Giant cell central lesion is characteristic of the gnathic bones, being a non-odontogenic benign tumor. Classified as a predominantly slow grotwh, well-circumscribed and asymptomatic lesion usually diagnosed through routine examination or in some and more advanced cases once it begins to create some aesthetic-anatomical alteration or when the patient starts complaining of some located discomfort in the region. Objective: To present a clinical case of central giant cell lesion and its resolution involving surgical approach and second management, which includes homeopathy as a therapeutic proposal. Case presentation: central giant cell lesion located in the premaxilla region in a 4 years old female patient. After radiographic, tomographic and blood exams evaluation, followed by incisional biopsy and diagnostic, leading to surgical approach to remove the entire lesion by curettage with Carnoy's solution application under general anesthesia. After appearance of radiopaque imaging in the proservation examinations, the non-invasive treatment by corticoid injection and homeopathy got started aiming the reduction of cicatricial tissue's suggestive area and neoformation of the bone. Conclusions : approaches that are more conservative can be, in many cases, a plausible option that ends up ridding the patient of mutilating surgeries(AU)

In order to compare the efficacy of lidocaine and articaine for pain control during third molar surgery, 160 patients presenting bilateral asymptomatic impacted mandibular third molars were selected. They received 1.8 mL of 2% lidocaine with epinephrine 1:100,000 during inferior alveolar nerve block. In group 1 (n = 80), an infiltrative injection of 0.9 mL of 2% lidocaine with epinephrine 1:100,000 was performed in buccal-distal mucosa of the third molar. Group 2 (n = 80) received 0.9 mL of 4% articaine with epinephrine 1:100,000 in the contralateral side. All procedures were performed at the same visit, by a single operator, in a double-blind and parallel design. The duration of each surgery and the moment when the patient expressed pain were noted. Data were analyzed by nonpaired t test and chi-square test (alpha = 5%). Duration of surgery did not differ (p = .83) between Groups 1 (19.8 ± 2.3 minutes) and 2 (19.7 ± 3.0 minutes). Pain was expressed more in group 1 (26.3%) than in group 2 (10%) (odds ratio = 3.2, p = .0138). In both groups, tooth sectioning was the most painful event (p < .0001). No influence of gender (p = .85) or age (p = .96) was observed in pain response. Buccal infiltration of 4% articaine with epinephrine 1:100,000 showed more efficacy than 2% lidocaine with epinephrine 1:100,000 when used in combination with inferior alveolar nerve block in controlling intraoperative pain related to impacted mandibular third molar surgery.

This randomized double-blind crossover trial investigated the discomfort associated with 2 injection speeds, low (60 seconds) and slow (100 seconds), during inferior alveolar nerve block by using 1.8 mL of 2% lidocaine with 1 : 100,000 epinephrine. Three phases were considered: (a) mucosa perforation, (b) needle insertion, and (c) solution injection. Thirty-two healthy adult volunteers needing bilateral inferior alveolar nerve blocks at least 1 week apart were enrolled in the present study. The anesthetic procedure discomfort was recorded by volunteers on a 10-cm visual analog scale in each phase for both injection speeds. Comparison between the 2 anesthesia speeds in each phase was performed by paired t test. Results showed no statistically significant difference between injection speeds regarding perforation (P = .1016), needle placement (P = .0584), or speed injection (P = .1806). The discomfort in all phases was considered low. We concluded that the 2 injection speeds tested did not affect the volunteers' pain perception during inferior alveolar nerve blocks.

OBJECTIVES: The aim of the present study was to evaluate the effect of Erythrinamu lungu on the control of dental anxiety in patients who had under gone bilateral extraction of asymptomatic, impacted mandibular third molars. MATERIAL AND METHODS: In a randomized, double-blind, crossover study, 30 healthy volunteers (5 men and 25 women, over 18 years of age), received either 500mg of E.mulungu (MulunguMatusa®) or 500 mg of placebo, p.o., one hour before surgical procedure. The level ofanxiety was assessed through questionnaire sand physical parameters, such as blood pressure, heart rate andoxygen saturation. Data were analyzed by Chi-square test, ANOVA (Tukey test) and Friedman with significance level of 5%. RESULTS: A higher preference (Chi-square, p = 0.0062) for E. mulungu was observed for both genders. Volunteers with higher anxiety levels tended to to prefer E. mulungu. No statistically significant differences were verified in blood pressure (one-way ANOVA, p = 0.1259), heart rate (Friedman, p> 0.05) and oxygen saturation (Friedman, p = 0.7664) among periods and types of treatments. CONCLUSIONS: E. mulungu showed an anxiolytic effect without significant changes in physiological parameters. It could be considered as an alternative to control the anxiety in adult patients undergoing mandibular thirdmolars surgery.
