O objetivo do presente estudo foi avaliar a eficácia da analgesia preemptiva na cirurgia de extração de terceiros molares inclusos. Nesse estudo duplo cego, randomizado e pareado, os pacientes foram submetidos à extração de terceiros molares inferiores bilaterais em dois tempos distintos. Em uma das duas cirurgias, no pré-operatório os pacientes fizeram uso de Cetoprofeno 150 mg via oral a cada 12 horas durante dois dias antes e, após a cirurgia, continuaram a medicação por mais três dias. Em outra cirurgia, fizeram uso de um comprimido placebo no pré-operatório a cada 12 horas durante dois dias antes e, após a cirurgia, fizeram uso de Cetoprofeno 150 mg a cada 12 horas por três dias. O analgésico de resgate utilizado foi o Paracetamol 750 mg via oral. A dor pós-operatória foi avaliada por meio de Escala Visual Analógica, Escala Nominal e quantidade de consumo de analgésicos de resgate. Os resultados não mostraram diferença significante entre o controle e cetoprofeno preemptivo na redução da dor pós-operatória e no consumo de analgésicos de resgate. Concluiu-se que neste modelo experimental, a analgesia preemptiva não se mostrou eficaz na redução da dor pós-operatória. / The aim of this study was to evaluate the effectiveness of the preemptive analgesia in the third molar surgery. In this double blind study, randomized and paired, the patients were submitted to the extraction of the third molar bilateral inferiors in two distinct times. In one of the two surgeries, during the two-day preoperative the patients made useof150 mg of ketoprofenoralevery12 hours and, after the surgery, they kept taking this medication for three days. In the other surgery, a placebo pill was used in the preoperative, also every 12 hours, for two days and, after the surgery, ketoprofen 150 mg was used every 12 hours for three days. The rescue analgesic used was the paracetamol 750 mg oral. Postoperative pain was evaluated by making use of the Analogical Visual Scale, the Nominal Scale and the amount of rescue analgesic consumption. The results did not show significant difference between the control and the preemptive ketoprofen in the reduction of postoperative pain and in the rescue analgesic consumption. We can conclude that in this experimental model, the preemptive analgesia did not prove to be efficient in the reduction of postoperative pain.

O uso de antibióticos para reduzir a infecção pós-operatória em cirurgia de terceiro molar permanece controverso. O objetivo deste estudo foi avaliar a eficácia da terapêutica com Amoxicilina em múltiplas doses para a prevenção de infecção em pacientes submetidos à extração de terceiro molar inferior com posição 2B (classificação de Pell & Gregory). O estudo foi prospectivo, cego, randomizado, duplo, controlado por placebo, com 32 pacientes. Cada paciente atuou como seu próprio controle usando a técnica de boca dividida. Um terceiro molar inferior foi retirado sob a cobertura de antibióticos no pós-operatório (500 mg de amoxicilina a cada 8 horas durante 7 dias) e o outro foi removido sem cobertura antibiótica pós-operatória (cápsulas de placebo a cada 8 horas durante 7 dias), mas em ambas cirurgias foi administrada dose única no pré-operatório de 1 g de amoxicilina. Os seguintes parâmetros foram avaliados no pré-operatório, no quarto e sétimo dias pós-operatórios: trismo, edema facial, temperatura corporal, linfadenopatia, infecção, disfagia e dor. Não houve diferença estatisticamente significativa nos parâmetros avaliados entre os pacientes operados (p> 0,05). Resultado do estudo mostrou que a administração de amoxicilina em dose única pré-operatória e em doses múltiplas pós-operatórias não se mostrou mais eficaz do que a administração somente em dose única pré-operatória com relação aos parâmetros clínicos avaliados nas exodontias de terceiros molares inferiores. / The use of antibiotics to reduce postoperative infection in third molar surgery remains controversial. The goal of this study was to evaluate the efficacy of multi-dose Amoxicilina therapy for the prevention of infection in patients undergoing lower third molar extraction with position 2B (Pell & Gregory classification). The study was a prospective, randomized, double blind, placebo-controlled trial with 32 patients. Each patient acted as their own control using the split-mouth technique. One lower third molar were removed under antibiotic cover postoperative (500 mg amoxicillin 8 hourly for 7 days) and the other were removed without antibiotic cover postoperative (placebo capsules 8 hourly for 7 days), but both surgery was administered preoperatively single dose of 1g of amoxicillin. The following parameters were evaluated on the preoperative and fourth, seventh days postoperative: trismus, facial swelling, body temperature, Lymphadenopathy, infection, dysphagia and pain. There was no statistically significant difference in the parameters evaluated between patients operated (p > 0.05). Results of the study showed that administration of amoxicillin single dose preoperative and postoperative multiple doses was not more effective than single dose administration only pre-operative with respect to clinical parameters evaluated in the lower third molar extractions.
