Comparação da articaína e lidocaína no bloqueio do nervo alveolar inferior / Comparison of articaine and lidocaine in alveolar nerve block lower

Siviero, Marcelo 30 January 2009 (has links)
O objetivo dessa pesquisa foi avaliar o tempo de latência e duração pulpar anestésica da dose de 1,8ml das seguintes soluções anestésicas locais: cloridrato de articaína 4% associado à epinefrina 1:100.000 (ART 100) e 1:200.000 (ART 200) e cloridrato de lidocaína 2% associado à epinefrina 1:100.000 (LIDO 100) no bloqueio convencional do nervo alveolar inferior. A amostra do experimento consistiu de vinte pacientes normorreativos, submetidos a três consultas para tratamento restaurador de baixa complexidade em três dentes posteriores inferiores. Os períodos de latência e duração da anestesia local na polpa dentária foram monitorados com um estimulador pulpar elétrico (Vitality Scanner Model 2006®-SybronEndo, CA, EUA). Para análise e comparação dos resultados da latência e duração pulpar das três soluções anestésicas locais foi utilizado o teste paramétrico ANOVA e o teste auxiliar de Bonferroni com nível de significância fixado em 5% (p<0,05). Em relação ao período de latência pulpar não houve diferença estatisticamente significante entre nenhuma das três soluções anestésicas locais utilizadas (p > 0,05). Já em relação ao período de duração pulpar houve diferença estatisticamente significante entre ART 100 e LIDO 100 (p=0,000) e entre ART 200 e LIDO 100 (p=0,000). Portanto, a latência das duas soluções de articaína foram similares à solução de lidocaína, mas ambas apresentaram duração de ação anestésica maior do que a solução de lidocaína. / The aim of this study was to evaluate the time of onset and duration of pulp anesthetic dose of 1.8 ml of local anesthetic solutions following: 4% hydrochloride articaine associated with epinephrine 1:100.000 (ART 100) and 1:200.000 (ART 200) and 2% hydrochloride of lidocaine associated with epinephrine 1:100.000 (LIDO 100) in alveolar nerve block lower. The sample of the experiment consisted of twenty healthy patients, underwent three appointments for restorative treatment of low complexity in three subsequent lower teeth. The periods of onset and duration of local anesthetic in dental pulp were monitored with an electric stimulator pulp (Vitality Scanner®, Model 2006 - SybronEndo, CA, USA). To analyze and compare the results of onset and duration of the three pulp solutions local anesthetic was used parametric ANOVA test and the test of Bonferroni help with significance level set at 5% (p < 0.05). For the period of onset there was no statistically significant difference between any of the three approaches used local anesthetic (p> 0.05). Already in relation to the duration of pulp statistically significant difference between ART 100 and LIDO 100 (p = 0000) and between ART 200 and LIDO 100 (p = 0000). Therefore, the onset of the two solutions of articaine were similar to the solution of lidocaine, but both showed duration of anesthetic action superior to the solution of lidocaine.

Paraesthesia Following Dental Local Anaesthetic Administration in the United States

Garisto, Gabriella Amneris 06 January 2011 (has links)
Background: Several studies have suggested that the likelihood of paraesthesia may depend on the local anaesthetic (LA) used. The purpose of this study was to analyze reports of paraesthesia among dental LAs used in the U.S. Methods: Reports of paraesthesia involving LAs between November 1997 through August 2008 were obtained from the U.S. Food and Drug Administration Adverse Event Reporting System. Chi-Square analysis compared expected frequencies, based on U.S. LA sales data, to observed reports of oral paraesthesia. Results: During the study period 248 cases of paraesthesia following dental procedures were reported. Most (94.5%) cases involved mandibular nerve block. The lingual nerve was affected in 89.0% of cases. Reports involving 4%-prilocaine and 4%-articaine were 7.3-times and 3.6-times, respectively, greater than expected (χ2, p<0.0001) based on LA usage by U.S. dentists. Conclusions: Consistent with previous reports, these data suggest that paraesthesia is more common following use of 4% LA formulations.

PROSPECTIVE EVALUATION OF THE EFFECT OF THE PRESENCE OF MANDIBULAR THIRD MOLARS DURING SAGITTAL SPLIT OSTEOTOMIES OF THE MANDIBLE

Doucet, Jean-Charles 24 March 2011 (has links)
Problem: Third molar removal in sagittal split osteotomies(SSOs) is recommended by some authors at least 6 months preoperatively to prevent unfavorable fractures. Others authors suggest concomitant removal. The purpose of this study was to investigate the effect of third molars during SSOs. Methods: A prospective study of 677 SSOs was conducted. GroupI consisted of 331 SSOs and third molar removal. GroupII consisted of 346 SSOs without third molar. Intraoperative and postoperative evaluations were recorded. Results: The overall rate of unfavorable fractures was 3.1%, with incidences of 2.4% in GroupI, compared to 3.8% in GroupII(P=0.3). The rate of IAN entrapment was lower in GroupI(37.2%) than in GroupII(46.5%;P=0.01). Third molars increased procedural time by 1.7 minutes. Neurosensory deficits were higher in GroupII. Conclusion: Removal of third molars during SSOs is not associated with increased incidence of unfavorable fractures. Their presence decreases IAN entrapment, improve neurosensory recovery, but slightly increases operating time.

Eficácia anestésica da mepivacaína e da lidocaína no bloqueio mandibular em molares inferiores com pulpite irreversível / Anesthetic efficacy of mepivacaine and lidocaine in mandibular block in irreversible pulpitis molars

Renata Pieroni Visconti 20 July 2010 (has links)
Neste estudo, randomizado, duplo cego, avaliamos a eficácia anestésica em quarenta e dois pacientes, do Setor de Urgência da Faculdade de Odontologia da Universidade de São Paulo, com pulpite irreversível, que receberam mepivacaína 2% (n=21) ou lidocaína 2% (n=21) associadas à epinefrina 1:100.000 para bloqueio do nervo alveolar inferior (BNAI). O sinal subjetivo de anestesia do lábio e língua, a presença de anestesia pulpar e ausência de dor durante o procedimento de pulpectomia foram avaliados, respectivamente, por indagação ao paciente, pelo testador elétrico pulpar (TEP) e pela escala de dor verbal (VAS). Pela técnica pterigomandibular indireta das três posições, foi injetado primeiramente um tubete (1,8mL), e depois de 10 minutos, foi testada a anestesia pulpar (AP), pelo TEP, por duas leituras negativas ao estímulo máximo (80A) do aparelho. Quando não instalada a AP, um segundo tubete (mais 1,8mL) era reinjetado. Confirmada a anestesia pulpar, iniciava-se a pulpectomia. O sucesso do BNAI foi definido como a capacidade de acessar a câmara pulpar e a realização da pulpectomia sem relato de dor (VAS) pelo paciente (escore 0 ou 1), enquanto o insucesso foi caracterizado pelo incomodo/dor (escore 2 ou 3), que impedisse a continuação. Nesse caso, um terceiro e último tubete foi dado por técnicas complementares (intraligamentar ou intrapulpar) para finalizar o procedimento. Na análise estatística utilizou-se o teste Exato de Fisher e ANOVA com nível de significância fixado em 5%. Obtivemos que no grupo Mepivacaína com 1,8mL, a taxa de anestesia pulpar (AP) foi de 52% (11/21), e sucesso no BNAI de 55% (6/11); a injeção de mais 1,8mL (2º tubete) aumentou a AP para 86% (18/21) e o sucesso no BNAI para 55% (10*/18). No Grupo Lidocaína, com 1.8mL, a taxa da AP foi de 33% (7/21), o BNAI foi de 0%; com mais 1,8mL (2º tubete), a AP aumentou para 67% (14/21) e sucesso no BNAI para 14% (2*/14) (*com diferença estatística onde p0,05). A mepivacaína com volume menor proporcionou, clinicamente, maior índice de anestesia pulpar e sucesso do BNAI (pulpectomia total), e permitiu chegar mais próximo da polpa quando comparada a lidocaína. Concluímos que a mepivacaína obteve melhores resultados no sucesso do BNAI para a realização da pulpectomia em molares inferiores com pulpite irreversível. / The aim of this, double blind randomized study, was to evaluate the anesthetic efficacy of inferior alveolar nerve block (IANB) using 2% mepivacaine and 2% lidocaine both associated with adrenaline 1:100,000 in molars with irreversible pulpitis. The sample of these study consisted of forty-two healthy patients diagnosed with irreversible pulpitis actively experiencing pain. For blocking the IAN was established the following protocol: injection of one cartridge (1.8 mL) by the technique pterigomandibular of three indirect positions, expected 10 minutes and electric pulp test (EPT) Vitality Scanner®-SybronEndo, USA was accomplishment. If tooth sensitivity pain persisted another cartridge (plus 1.8 mL) was given by the same technique and the same methodology was performed. The pulpectomy was continued after the confirmation of pulpal anesthesia, which was established as the lack of response at maximum stimulation (80A) of EPT. In cases where the patient reported pain during pulpectomy even confirmed the blockage, a third cartridge was given by complementary techniques (intraligamentary or intrapulpal) to complete the endodontic procedure. The anesthetic efficacy in IANB was established when the pulpectomy was performed without report of pain and without complementation. For analysis and comparison of results we used the Fisher exact statistical test and ANOVA with significance level set at 5%. Regarding the effectiveness of the anesthetic with 1,8 mL mepivacaine, determined pulpar anesthesia (PA) was 52% (11/21), and success in IANB (pulpectomy) 55% (6/11), the most injection of 1,8 mL, increased 86% (18/21) for AP and success in IANB to 55% (10*/18). In the lidocaine group, with 1.8mL, AP rate was 33% (7/21), the IANB was 0%, with a further 1.8 mL (cartridge 2) the AP increased to 67% (14/21) and success was to IANB 14 % (2*/14), (*statistically difference p 0.05). Mepivacaine with smaller volume clinically provided a higher rate of pulpal anesthesia and most successful of IANB (pulpectomy total), allowing to reach nearest dental pulp than lidocaine. Concluded that mepivacaine performed better in success of IANB (pulpectomy) that lidocaine in molars with irreversible pulpitis

Estudo da prevalência da posição vestíbulo-lingual do canal mandibular por meio da tomografia computadorizada helicoidal / Prevalency study of the vestibulo-lingual position from the mandibular canal by helical computerized tomography

Cláudio Tizzani Coppedé 23 September 2008 (has links)
O trajeto do canal da mandíbula é oblíquo com sentido póstero-anterior, apresenta-se próximo da cortical óssea alveolar medial, até atingir a face mesial do primeiro molar inferior, a partir desta região aproxima-se da lâmina óssea alveolar lateral até alcançar o forame mentual. Radiograficamente, o canal da mandíbula se apresenta, como uma linha radiolúcida delimitada por duas linhas radiopacas. Existem diversos métodos de exames radiográficos que possibilitem a avaliação do complexo maxilo-mandibular. Estudos mostram que a Tomografia Computadorizada (TC) foi considerado o melhor método para a avaliação do trajeto no sentido vestíbulo-lingual do canal da mandíbula. Foi proposto analisar a morfologia no sentido vestíbulo-lingual das variações do trajeto do canal da mandíbula em imagens de TC utilizando o software Dental Slice®. Com a ferramenta mensuração deste software , avaliou-se 100 TC bilateralmente, criando-se três retas. Uma horizontal (vestíbulo-lingual), dividindo o canal ao meio, e duas retas verticais, tangenciando a face externa lingual e vestibular da cortical do canal. Para análise dos dados utilizou os testes de normalidade, teste de hipótese (teste t e ANOVA) e teste de aderência Anderson Darling. Concluiu-se que existe uma tendência da presença de pouca variabilidade, entre os lados direito e esquerdo; a porção do canal mais próxima ao forame mentual apresenta-se vestibularizado, e na região posterior lingualizado; há necessidade da avaliação topográfica do canal da mandíbula por meio da Tomografia Computadorizada. / The course of the mandibles canal is oblique with posterior-anterior direction, it comes close to the medial cortical alveolar bony, until reaching the mesial face of the first inferior molar, starting from this area, it approaches of the lateral cortical alveolar bony until reaching the forame mentual. Radiographically, the manbible´s canal comes, as a radiolucent line defined by two radiopaque lines. Several methods of exams radiographyc that facilitate the evaluation of the complex maxilo-mandibular. Studies show that the Computerized Tomography (TC) is the best method for consider the evaluation of the course in the vestibule-lingual direction of the mandibles canal. It was intended to analyze the morphology in the vestibule-lingual direction of the variations of the course the mandibles canal in images of TC using the Dental Slice® software. With the mensuration tool of this software, 100 TC was evaluated bilaterally, being created three straight line. A horizontal one (vestibule-lingual), dividing the canal in the middle, and two vertical straight line, being tangent to the lingual external face and vestibular of the canals cortical. For analysis of the data it used the normality tests, hypothesis test (tests t and ANOVA) and test of adherence Anderson Darling. It conclude that a tendency exists the presence of little variability, among the sides right and left. The canal close to the forame mentual presents vestibular direction, and in the posterior area on lingual direction. And Confirm the need of the use of TC in the topographical evaluation of the mandibles canal.
