Pain due to administration of local anesthetics is the primary reason for patients' fear and anxiety, and various methods are used to minimize it. This study aimed to measure the degree of pain during administration of anesthesia and determine the latency time and duration of pulpal anesthesia using two anesthetic methods in the maxilla. Materials and Methods: A randomized, single-blind, split-mouth clinical trial was conducted with 41 volunteers who required class I restorations in the maxillary first molars. Local anesthesia was administered with a needleless jet injection system (experimental group) or with a carpule syringe (control) using a 30-gauge short needle. The method of anesthesia and laterality of the maxilla were randomized. A pulp electric tester measured the latency time and duration of anesthesia in the second molar. Visual analogue scale (VAS) was used to measure the degree of pain during the anesthetic method. Data were tabulated and then analyzed by a statistician. The t-test was used to analyze the differences between the groups for basal electrical stimulation. Duration of anesthesia and degree of pain were compared using the Mann-Whitney test. A 5% significance level was considered. Results: There was no statistical difference in the basal electrical stimulation threshold (mA) and degree of pain between the two methods of anesthesia (p>0.05). Latency time was 2 minutes for all subjects. The duration of pulpal anesthesia showed no statistical difference (minutes) between the two methods (p<0.001), with a longer duration for the traditional method of anesthesia (median of 40 minutes). Conclusions: The two anesthetics methods did not differ concerning the pain experienced during anesthesia. Latency lasted 2 minutes for all subjects; the traditional infiltration anesthesia resulted in a longer anesthetic duration compared with the needleless jet injection.

ResumoIntrodução: Medo e ansiedade são comuns a pacientes que requerem tratamento odontológico e, em se tratando de procedimentos cirúrgicos, a ansiedade pode tornar-se um fator complicador, a partir do momento em que a alteração dos sinais vitais do paciente pode gerar situações de emergência. Objetivo: Avaliar o grau de ansiedade pré-operatória dos pacientes submetidos a cirurgias orais, identificando qual procedimento cirúrgico causa mais ansiedade nos pacientes e qual o momento cirúrgico causador de maior ansiedade. Material e método: Foram selecionados 200 pacientes que iriam se submeter a cirurgias bucais nos ambulatórios do Departamento de Odontologia da Universidade Federal de Sergipe. No dia da cirurgia, os pacientes respondiam à escala EAD, tendo sido avaliadas a frequência cardíaca (FC) e a pressão arterial sanguínea (PA), considerados dados basais dos parâmetros físicos empregados para a avaliação da ansiedade pré-operatória. Resultado: Não houve diferenças estatisticamente significantes (Kruskal-Wallis, p=0,6933) entre os tratamentos em relação à ansiedade. A correlação de Spearman (rS) entre os valores obtidos para a ansiedade e os valores de pressão arterial e frequência cardíaca revelou-se fraca (rS<0,2), embora significativa (p<0,05) entre os resultados. A anestesia foi o momento que produziu maior ansiedade (Kruskal-Wallis, p<0,05), em relação aos demais momentos. Conclusão: A ansiedade teve influência no aumento da frequência cardíaca e da pressão arterial sistólica, tornando-se importante o seu controle pelo cirurgião-dentista para evitar complicações no decorrer da cirurgia.Descritores: Ansiedade; cirurgia; frequência cardíaca; pressão arterial. AbstractIntroduction: Fear and anxiety are common in patients who require odontological treatment. During surgical procedures, anxiety can become a complicating factor from the moment in which the change of patient's vital signs can generate emergency situations. Objective: Evaluate the degree of preoperative anxiety of patients submitted to oral surgery, to identify which surgical procedure causes more anxiety in patients and also which surgical moment is causing greater anxiety. Material and method: 200 patients were selected for oral surgery at the clinics of the Department of Dentistry, Federal University of Sergipe. On the day of surgery, patients answered the EAD scale and their heart rate (HR) and blood pressure (BP) were evaluated. These data served as baseline of the physical parameters used in the evaluation of preoperative anxiety. Result: Statistically, there were no significant differences (Kruskal-Wallis test, p=0.6933) between treatments regarding anxiety. The Spearman correlation (rS) between the values obtained for anxiety, blood pressure levels and heart rate showed a weak correlation (rs <0.2), although significant (p<0.05) between the results. The anesthesia was the moment that produced greater anxiety (KruskalWallis test, p<0.05) compared to the other moments. Conclusion: Anxiety has a connection with the increase of the heart ra...

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.

The maxillary sinus or antrum is the largest of the paranasal sinuses. It is located in the maxillary bone and has a proximity to the apexes of upper molars and premolars, which allows it to form a direct link between the sinus and the oral cavity. Dislocation of a foreign body or tooth to the interior of a paranasal sinus is a situation that can occur as a result of car accidents, firearm attacks, or iatrogenic in surgical procedures. Therefore, it is necessary to know how to treat this kind of situation. This study's objective is to report the case of a 23-year-old female patient, leucoderma, who sought treatment from the Surgical Unit at the Dental Faculty of the Federal University of Sergipe. She had a history of pain and edema in the right side of the genian region and two failed attempts at removing dental unit (DU) 18. The extraoral clinical exam revealed intense edema of the left hemiface with signs of infection, excoriation of the labial commissure, hematoma, a body temperature of 39°C, and a limited ability to open her mouth. The patient was medicated and treated surgically. The tooth was removed from the maxillary sinus with caution, as should have been done initially.

INTRODUÇÃO: No âmbito da clínica odontológica, o bloqueio do nervo alveolar inferior é o mais utilizado; todavia, diversos estudos têm mostrado as mais altas taxas de fracasso, as quais, normalmente, têm como motivo a falha na observação da posição, da forma e da anatomia dos nervos. Essas falhas decorrentes da variação anatômica do nervo alveolar inferior já vêm sendo estudadas na literatura, através de estudos com a análise de radiografias panorâmicas, como proposto neste estudo. OBJETIVO: O objetivo deste estudo foi verificar a ocorrência e a prevalência das variações anatômicas, bem como a correlação das variações do canal da mandíbula com lado e sexo, que podem ocorrer no canal mandibular, por meio de radiografias panorâmicas de pacientes atendidos no Departamento de Odontologia da Universidade Federal de Sergipe (UFS). MATERIAL E MÉTODO: Foram analisadas 1.500 radiografias panorâmicas de pacientes atendidos pelo Departamento de Odontologia da Universidade Federal de Sergipe (UFS). Imagens radiográficas foram observadas sobre um negatoscópio, utilizando-se uma máscara preta ao redor das radiografias, em ambiente com luminosidade apropriada. RESULTADO: Neste estudo, foram observados 5,3% de bifurcações do canal mandibular; 47,5% de canais altos; 16,8% de canais intermediários; 27,1% de canais baixos, e 8,6% de canais com outras variações. CONCLUSÃO: Baseando-se na altura do canal mandibular, houve maior prevalência dos canais altos do que os demais nas mulheres, sendo que não houve diferenças entre os gêneros com relação aos demais tipos e lados afetados. Na classificação dos canais bífidos, não houve diferença estatisticamente significante entre homens e mulheres. Observou-se que a maior prevalência foi para canais sem bifurcação.
