ABSTRACT

La evidencia científica presente en la literatura indica que el cannabis puede ser utilizado con fines terapéuticos para tratar distintas afecciones odontológicas. Dado el acceso sencillo a la cavidad bucal, las distintas formulaciones de cannabis pueden aplicarse de forma tópica. La aplicación local de dosis bajas de cannabis ha demostrado alta efectividad para tratar distintas afecciones bucales, constituyendo un tratamiento seguro con baja probabilidad de generar repercusiones sistémicas indeseadas. En la actualidad, está siendo incorporado a materiales convencionales de uso e higiene odontológica con la finalidad de aprovechar sus efectos terapéuticos. El cannabis tiene múltiples usos en odontología: como componen-te de enjuagues bucales y soluciones para la desinfección de conductos radiculares, en tratamientos de trastornos de ansiedad bucal, como complemento en terapias oncológicas, como analgésico para atenuar el dolor inflamatorio y el neuropático, como miorrelajante y condroprotector para tratar trastornos de articulación témporomandibular (ATM) y bruxismo, como osteomodulador para el tratamiento de patologías que comprometen la integridad ósea, como la enfermedad periodontal y la osteoporosis, y para la cicatrización ósea asociada a fracturas, extracciones dentarias e implantes, y como inmunomodulador con potencial terapéutico para tratar patologías autoinmunes como las enfermedades reumáticas. El trata-miento local con cannabis es efectivo, bien tolerado por el paciente y con pocos efectos adversos. Por lo tanto, se puede concluir que el cannabis aporta un enorme abanico de posibilidades terapéuticas para tratar distintas afecciones odontológicas, aunque aún se requiere mayor cantidad de estudios científicos que avalen su utilización en cada situación fisiopatológica particular (AU)


The scientific evidence present in the literature indicates that cannabis can be used for therapeutic purposes to treat different dental conditions. Given the easy access to the oral cavity, the different cannabis formulations can be applied topically. The local application of low doses of cannabis has shown high effectiveness in treating different oral conditions, constituting a safe treatment with a low probability of generating unwanted systemic repercussions. It is currently being incorporated into conventional materials for dental use and hygiene in order to take advantage of its therapeutic effects. Cannabis has multiple uses in dentistry: as a component of mouthwashes and solutions for disinfecting root canals, in the treatment of oral anxiety disorders, as a complement in oncological therapies, as an analgesic to reduce inflammatory and neuropathic pain, as a muscle relaxant and chondroprotective to treat temporomandibular joint disorders and bruxism, as an osteomodulator for the treatment of pathologies that compromise bone integrity, such as periodontal disease and osteoporosis, and or bone healing associated with fractures, dental extractions and implants, and as immunomodulator with therapeutic potential to treat autoimmune pathologies such as rheumatic diseases. Local treatment with cannabis is effective, well tolerated by the patient and with few adverse effects. Local treatment with cannabis is effective, well tolerated by the patient and with few adverse effects. Therefore, it can be concluded that cannabis provides an enormous range of therapeutic possibilities to treat different dental conditions, although more scientific studies are still required to support its use in each particular pathophysiological situation (AU)

ABSTRACT

Abstract When exposure of the pulp to external environment occurs, reparative dentinogenesis can be induced by direct pulp capping to maintain pulp tissue vitality and function. These clinical situations require the use of materials that induce dentin repair and, subsequently, formation of a mineralized tissue. Objective: This work aims to assess the effect of tricalcium silicate cements and mineral trioxide aggregate cements, including repairing dentin formation and inflammatory reactions over time after pulp exposure in Wistar rats. Methodology: These two biomaterials were compared with positive control groups (open cavity with pulp tissue exposure) and negative control groups (no intervention). The evaluations were performed in three stages; three, seven and twenty-one days, and consisted of an imaging (nuclear medicine) and histological evaluation (H&E staining, immunohistochemistry and Alizarin Red S). Results: The therapeutic effect of these biomaterials was confirmed. Nuclear medicine evaluation demonstrated that the uptake of 99mTc-Hydroxymethylene diphosphonate (HMDP) showed no significant differences between the different experimental groups and the control, revealing the non-occurrence of differences in the phosphocalcium metabolism. The histological study demonstrated that in mineral trioxide aggregate therapies, the presence of moderate inflammatory infiltration was found after three days, decreasing during follow-ups. The formation of mineralized tissue was only verified at 21 days of follow-up. The tricalcium silicate therapies demonstrated the presence of a slight inflammatory infiltration on the third day, increasing throughout the follow-up. The formation of mineralized tissue was observed in the seventh follow-up day, increasing over time. Conclusions: The mineral trioxide aggregate (WhiteProRoot®MTA) and tricalcium silicate (Biodentine™) present slight and reversible inflammatory signs in the pulp tissue, with the formation of mineralized tissue. However, the exacerbated induction of mineralized tissue formation with the tricalcium silicate biomaterial may lead to the formation of pulp calcifications

ABSTRACT

Abstract Inferior alveolar nerve block has a high failure rate in the treatment of mandibular posterior teeth with irreversible pulpitis. The aim of this study was to compare the anesthetic efficacy of 4% articaine, 2% lidocaine and 2% mepivacaine, all in combination with 1:100,000 epinephrine, in patients with irreversible pulpitis of permanent mandibular molars during a pulpectomy procedure. Sixty-six volunteers from the Emergency Center of the School of Dentistry, University of São Paulo, randomly received 3.6 mL of local anesthetic as a conventional inferior alveolar nerve block (IANB). The subjective signal of lip numbness, pulpal anesthesia and absence of pain during the pulpectomy procedure were evaluated respectively, by questioning the patient, stimulation using an electric pulp tester and a verbal analogue scale. All patients reported the subjective signal of lip numbness. Regarding pulpal anesthesia success as measured with the pulp tester, the success rate was respectively 68.2% for mepivacaine, 63.6% for articaine and 63.6% for lidocaine. Regarding patients who reported no pain or mild pain during the pulpectomy, the success rate was, respectively 72.7% for mepivacaine, 63.6% for articaine and 54.5% for lidocaine. These differences were not statistically significant. Neither of the solutions resulted in 100% anesthetic success in patients with irreversible pulpitis of mandibular molars.


Resumo O bloqueio do nervo alveolar inferior apresenta uma alta taxa de falha para o tratamento de dentes posteriores mandibulares com pulpite irreversível. O objetivo deste estudo foi comparar a eficácia anestésica da articaína 4%, lidocaína 2% e mepivacaína 2%, todas em combinação com epinefrina 1:100.000, em pacientes com pulpite irreversível de molares mandibulares durante um procedimento de pulpectomia. Sessenta e seis voluntários do Centro de Emergência da Faculdade de Odontologia da Universidade de São Paulo receberam aleatoriamente 3.6 mL de anestésico local no bloqueio convencional do nervo alveolar inferior (BNAI). O sinal subjetivo de dormência do lábio, anestesia pulpar e ausência de dor durante o procedimento de pulpectomia foram, respectivamente, avaliados pelo interrogatório do paciente, usando um estimulador pulpar elétrico e uma escala analógica verbal. Todos os pacientes relataram o sinal subjetivo de dormência do lábio. Em relação ao sucesso da anestesia pulpar medido com o Pulp Tester, a taxa de sucesso foi, respectivamente, 68.2% para mepivacaína, 63,6% para articaína e 63,6% para lidocaína. Relativamente aos pacientes que relataram nenhuma dor ou dor leve, durante a pulpectomia, a taxa de sucesso foi, respectivamente, 72.7% para mepivacaína, 63.6% para articaína e 54,5% para a lidocaína. Estas diferenças não foram estatisticamente significantes. Nenhuma das soluções resultou em 100% de sucesso anestésico em pacientes com pulpite irreversível de molares mandibulares.

ABSTRACT

O objetivo deste estudo foi avaliar o uso do cetorolaco de trometamina 10mg sublingual 30 minutos antes do procedimento de biopulpectomia em pacientes com pulpite irreversível com relação à dor antes do procedimento e nas 48 horas subsequentes, a quantidade de medicação consumida no pós-operatório e tempo esperado para sua utilização. Também foi avaliada a influência da anestesia intrapulpar, o uso da automedicação analgésica antes da procura pelo atendimento e diferença entre gêneros sobre os níveis de dor pré e pós-operatória. Propôs-se avaliar também a necessidade da presença do antibiótico na medicação intracanal, comparando o Otosporin® com hidrocortisona. Participaram da pesquisa 608 pacientes que procuraram o Setor de Urgência Odontológica da Faculdade de Odontologia de Bauru ou o Setor Odontológico do Pronto Socorro Central da Prefeitura Municipal de Bauru, sendo que 34 completaram de forma adequada o protocolo previsto. Foram divididos em 4 grupos que receberam cetorolaco ou placebo como medicação pré-operatória e Otosporin® ou hidrocortisona como medicação intracanal. Foram anotados os valores de intensidade de dor, em uma escala visual analógica, antes da medicação pré-operatória, antes do atendimento, após o atendimento, 1, 2, 4, 12, 24, 48 horas após e quando houve necessidade de medicação pós-operatória para alívio da dor. Também foi anotado se o paciente havia se automedicado e qual a droga utilizada, se houve necessidade de anestesia intrapulpar, a quantidade de medicação consumida pelo paciente no pós-operatório e o tempo esperado para seu consumo. Dos resultados observou-se que os pacientes que receberam cetorolaco como medicação pré-operatória tiveram uma redução significativa da dor em 30 minutos, quando comparado ao placebo. Foi observado que o tempo necessário para a ingestão de medicamentos pós-operatórios não demonstrou diferença significativa entre os grupos, assim como na quantidade de medicação ingerida. O tempo decorrido entre a primeira e a última dose de medicação pós-operatória também não demonstrou diferença estatística. Com relação a anestesia intrapulpar, 78% dos pacientes necessitaram desta técnica, mas devido ao pequeno tamanho da amostra obtida, não foi possível correlacionar o seu uso com a utilização da medicação pós-operatória. Para os pacientes que se automedicaram previamente, não houve diferença significativa em relação à dor inicial. Quando os gêneros foram comparados, não foi possível observar uma diferença estatística significante entre eles com relação aos parâmetros estudados. Também foram descritos no trabalho os motivos de não inclusão dos 574 pacientes que foram abordados durante a realização deste estudo. Com base nos resultados, conclui-se que o cetorolaco diminuiu expressivamente o nível de dor durante a espera pelo atendimento, porém com relação ao tempo esperado pelo paciente para tomar a primeira dose de medicação pós-operatória, a última dose, a quantidade de comprimidos e a frequência de ingestão não demonstrou a mesma diferença. Também não houve diferença no nível de dor inicial entre os pacientes que se automedicaram e os que não fizeram uso dessa prática. Devido ao pequeno número da amostra, não foi possível encontrar uma correlação entre o uso da técnica anestésica intrapulpar e medicação pós-operatória, sugerindo mais estudos futuros.(AU)


The aim of this study was to evaluate the use of ketorolac tromethamine (10mg sublingual taken 30 minutes before pulpectomy in patients with irreversible pulpitis) in pain reduction immediately before the procedure and the 48 subsequent hours, postoperative consumption of analgesic drugs and time for its use. The influence of intrapulpal anesthesia, the use of analgesic self-medication prior to the demand for care and gender difference on the levels of pre- and postoperative pain was also evaluated. It was also proposed assess the need for antibiotic presence in the intracanal medicament, comparing Otosporin® with hydrocortisone. A total of 608 patients who presented to Dental Urgency Sector from Dental School of Bauru (USP) or Emergency Dental Sector from Bauru City Hall were invited to participate, and 34 completed properly planned protocol. They were distributed in 4 groups that received either ketorolac or placebo as preoperative medication and Otosporin® or hydrocortisone as intracanal medication. The rates of pain intensity were recorded by means of a visual analogue scale before pretreatment medication, immediately before the appointment, 1, 2, 4, 12, 24, 48 hours after the appointment, and when there was taken post medication for postoperative pain relief. It was also recorded if the patient had self medicated and which the drug used and, if there was need intrapulpal anesthesia, amount of ketorolac and rescue medication (paracetamol 750mg) consumed by the patient postoperative time and the waitng time for consumption. The results showed that patients receiving Ketorolac as preoperative medication had a significant reduction of pain in 30 minutes compared to placebo. It was observed that the time required for the intake of postoperative drug showed no significant difference between groups, as well as the amount of medication intake. The time elapsed between the first and last dose of postoperative medication also showed no statistical difference. Concerning intrapulpal anesthesia, 78% of patients required for this technique, but because of the small sample size obtained it was impossible to correlate their use with the use of postoperative medication. For patients who practiced self medication previously, there was no significant difference with respect to initial pain. When genders were compared, it was not possible to observe a statistically significant difference between them regarding the parameters studied. Were also described in the study the reasons of non-inclusion of 574 patients that were addressed during this study. Based on the results, it is concluded that ketorolac significantly decreased the level of pain during the waiting time, but with respect to the time length for the patient to take the first dose of postoperative medication, the last dose, the number of tablets and taken frequency did not show the same difference. There was no difference in the initial level of pain among patients who practiced self medication and those who did not use this practice. Due to the small sample size, it was not possible to find a correlation between the use of the anesthetic technique intrapulpal and postoperative medication, suggesting more future studies.(AU)

ABSTRACT

BACKGROUND: Amitriptyline is one of the most common tricyclic antidepressants, which binds to pain sensory nerve fibers close to the sodium channel; hence, it could interact to some degree with receptors of local anesthetics. This study was designed to assess the additional analgesic effects of 2% Amitriptyline local gel administration in irreversible pulpitis pain of the molars. MATERIALS AND METHODS: This study was a randomized, double-blind clinical trial that was performed on 56 consented adult patients who did not receive enough analgesia after a lidocaine nerve block for their tooth pulpitis pain. Patients were treated with 0.2 ml of either 2% amitriptyline or placebo, which was directly injected into their mandibular molar pulp chamber after they had received two routine lidocaine injections. Patients were asked to score their pain as a mark on a 10-cm Visual Analogue Scale (VAS) at different timepoints: 0 (just before gel administration), 1, 3, 5, 7, and 9 minutes after the treatments. RESULTS: There was a 92.5% decrease in VAS scores of patients 9 minutes after amitriptyline administration compared to Time 0, while in the placebo group this difference was only 13.5%. Further, in the amitriptyline group, the VAS score at all timepoints was statistically different from Time 0 (P < 0.01). The overall pain reduction and its trend was significantly higher in the amitriptyline group compared with the placebo group (P < 0.001). CONCLUSION: Inter-pulp space administration of amitriptyline 2% gel for completing analgesia in irreversible pulpitis pain could be effective and useful as a conjunctive therapy to injections of local anesthetics.

ABSTRACT

Estudou-se a eficácia do hidróxido de cálcio sobre o E. faecalis em infecções endodônticas através de revisão sistemática. Utilizou-se fontes de catalogação identificadas eletronicamente por Medline. A heterogeneidade dos estudos não permitiu uma adequada combinação de resultados. Estudos in vitro mostraram a eficácia do hidróxido de cálcio sobre o E. faecalis. Nos estudos em humanos que satisfizeram os critérios de inclusão, de um total de 94 dentes o E. faecalis foi detectado em 34 dentes no início do tratamento, restando 11 após o processo de sanificação e o emprego da pasta de hidróxido de cálcio. A estimativa de êxito decorrente do sucesso clínico sinalizou evidência da eficácia do processo de sanificação sobre a microbiota endodôntica.

ABSTRACT

The aim of this study was to evaluate histological aspects of the pulp-dentin complex of dogs submitted to pulpotomy and capped with ethyl-cyanoacrylate and calcium hydroxide. Thirty dog teeth were divided into 2 groups of 15 as follows: Group 1 - ethyl-cyanoacrylate; Group 2 - calcium hydroxide. The pulpotomies were carried out following all of the treatment precautions recommended for dogs. After 30 days the specimens were submitted to histological preparation and were then blindly evaluated by a histologist. Data were analyzed statistically by the Fisher exact test, comparing the two groups. After 30 days, the presence of a hard tissue barrier was observed in 83.3 percent of Group 1, and in 100 percent of Group 2 (p = 0.478). A continuous hard tissue barrier was observed in 50 percent of the ethyl-cyanoacrylate group and 75 percent of the calcium hydroxide group (p = 0.652). It can be concluded that both materials induced hard tissue barrier formation, but Group 2 had a higher percentage than Group 1, with no significant statistical differences; the differences observed between the different barriers (continuous/non-continuous) were not significant between groups and there was no pulpal necrosis in either group.


O objetivo do presente estudo foi avaliar o aspecto histológico do complexo dentino-pulpar de cachorros quando capeado após a pulpotomia com etil-cianoacrilato e hidróxido de cálcio. Trinta dentes de cães foram divididos em 2 grupos de 15 da seguinte forma: Grupo 1 - Etil-cianoacrilato; Grupo 2 - Hidróxido de cálcio. A pesquisa foi realizada tomando-se todos os cuidados recomendados para o tratamento com os cães. Após 30 dias do procedimento realizado os espécimes foram submetidos ao preparo histológico e logo após foram avaliados de forma cega por um histologista. Os resultados foram analisados estatisticamente através do Teste Exato de Fisher. No grupo 1, 83,3 por cento e no grupo 2, 100 por cento dos dentes apresentaram a barreira de tecido duro (p = 0,478). A barreira de tecido duro contínua foi observada em 50 por cento dos casos tratados com etil-cianoacrilato e em 75 por cento dos com hidróxido de cálcio (p = 0,652). Pode-se concluir que tanto o grupo 1 como o grupo 2 induziram a formação da barreira de tecido duro, porém o grupo 2 teve um percentual maior do que o grupo 1, não havendo diferença estatisticamente significante; a diferença observada entre as estruturas das barreiras (contínuas e não-contínuas) não foi significante. A necrose pulpar não foi observada em nenhum grupo.

ABSTRACT

Las investigaciones anteriores han reportado mayor incidencia de agudizaciones endodónticas intercitas en pacientes alérgicos, debido a una reacción de hipersensibilidad inmediata. El propósito del presente estudio fue evaluar la eficacia del cromoglicato de sodio intracanal para prevenir las exacerbaciones en estos pacientes. En un estudio a doble ciego, se seleccionaron 30 pacientes atópicos que requerían tratamiento endodóntico en piezas vitales sin procesos infecciosos: 15 fueron medicados en forma intracanal con cromoglicato de sodio y 15 con solución salina, luego de la primera sesión. Los pacientes valoraron el grado de dolor como: ausente, leve, moderado y severo, registrándolo a las 8, 24 y 48 horas postoperatorias. Se observó una menor incidencia de dolor estadísticamente significativa en los casos medicados con cromoglicato de sodio comparado con la solución salina a las 8 horas (X2=16.20536, df=1;p=0.01683) y una diferencia estadísticamente significativa a favor del cromoglicato de sodio a las 24 horas

ABSTRACT

Este trabalho objetiva avaliar e discutir determinados fatores envolvidos no diagnóstico clínico da inflamaçäo pulpar. Diante de inúmeras dificuldades para o correto estabelecimento do diagnóstico clínico, pode-se questionar se as características da dor e o exame radiográfico permitem chegar ao elevado número de acertos ao determinar processos reversíveis e irreversível na polpa dental inflamada e se estes processos pertencem ao diagnóstico ou ao prognóstico. Observa-se, todavia, que o mais complexo é avaliar a extensäo da inflamaçäo e näo estabelecer o seu diagnóstico

ABSTRACT

Este estudio fue realizado en cobayos machos, a los cuales se les provocó pulpitis mediante la realización de cavidades clase V en los dientes incisivos. Se les aplicó indometacina y colchicina a razón de 7 mg/kg de peso y 2 mg/kg de peso respectivamente, por vía intraperitoneal. Previa anestesia se sacrificaron a los animales infiltrando formol al 10 por ciento en el ventrículo izquierdo para la fijación de las células inflamatorias. Por medio de la disección del maxilar y mandíbula se obtuvieron los dientes incisivos y se realizaron los cortes histopatológicos correspondientes para la cuantificación de las células inflamatorias con un objetivo de 400X. Se encontró que la pulpitis tratada con indometacina se elevó contra lo esperado. Cuando se utiliza la cochicina, pese a mostrar pulpitis en menor grado que con indometacina, aumentó ésta a nivel de polimorfonucleares. La colchicina por otra parte actuó sobre histiocitos y linfocitos, por lo tanto es posible afirmar que ambos medicamentos sí bloquean el desarrollo de la pulpitis, puesto que la indometacina actuó sobre linfocitos
