Synergistic anti-inflammatory effect of NSAIDs plus B vitamins administered pre and postoperatively in third molar surgery: randomized clinical trial / Efeito anti-inflamatório sinérgico da associação de AINEs e vitaminas do complexo B administrada no pré e pós-operatório de cirurgia de terceiros molares: ensaio clínico randomizado

Objective : The aim of the present study was to evaluate the synergistic anti-inflammatory effect of Non-steroidal anti-inflammatory drugs (NSAIDs) plus B vitamins administered pre and postoperatively in surgeries of impacted mandibular third molars. Material and Methods : Double-blind randomized clinical trial, sixty-six patients participated and were randomized into 2 groups. The control group was administered meloxicam 15 mg intramuscularly plus placebo orally and to the experimental group, meloxicam 15 mg intramuscularly plus vitamins B [B1, B6, and B12] orally; both treatments were administered preoperatively. The anti-inflammatory effect was evaluated by pain intensity, facial swelling (facial contour measurements), and mouth opening (distance between the upper and lower incisors) during the post-surgical phase. Student's t-test was performed for independent samples. Results : In all the evaluated times (1 hour, 6 hours, 12 hours, 24 hours, 2 days, and 3 days after the end of the surgery) the experimental group presented a significantly lower intensity of pain compared to the control group (p<0.05). The highest pain intensity was recorded at 6 hours (17.7 ± 9.1 mm in the experimental group and 34.5 ± 21.3 mm in the control group). Swelling and mouth opening were similar in both groups, at all times evaluated (p>0.05). Conclusion : In the present study, the administration of NSAIDs plus B vitamins (B1, B6, B12) produced lower intensity of pain compared to the administration of only NSAIDs. Nevertheless, swelling and mouth opening were similar in all evaluations for both study groups (AU)

Objetivo : O objetivo do presente estudo foi avaliar o efeito anti-inflamatório sinérgico de anti-inflamatórios não esteroidais (AINEs) com vitaminas do complexo B administrados no pré e pós-operatório de cirurgias de terceiros molares inferiores impactados. Material e Métodos: Ensaio clínico randomizado duplo-cego, 66 participantesque foram randomizados em 2 grupos. O grupo controle recebeu Meloxicam 15 mg por via intramuscular + placebo por via oral e o grupo experimental, Meloxicam 15 mg por via intramuscular + vitaminas B [B1, B6 e B12] por via oral; ambos os tratamentos foram administrados no pré-operatório. O efeito anti-inflamatório foi avaliado pela intensidade da dor, edema facial (medidas do contorno facial) e abertura da boca (distância entre os incisivos superiores e inferiores) durante a fase pós-cirúrgica. Foi aplicado o teste t de Student para amostras independentes. Resultados: Em todos os tempos avaliados (1 hora, 6 horas, 12 horas, 24 horas, 2 dias e 3 dias após o término da cirurgia) o grupo experimental apresentou uma intensidade de dor significativamente menor em relação ao grupo controle (p <0,05). A maior intensidade de dor foi registrada em 6 horas (17,7 ± 9,1 mm no grupo experimental e 34,5 ± 21,3 mm no grupo controle). Edema e abertura bucal foram semelhantes nos dois grupos, em todos os momentos avaliados (p>0,05). Conclusão: No presente estudo, a administração de AINEs com vitaminas do complexo B (B1, B6, B12) resultou em menor intensidade de dor em comparação com a administração apenas de AINEs. No entanto, o edema e a abertura da boca foram semelhantes em todas as avaliações para ambos os grupos de estudo (AU).

Asociación entre los niveles de linfocitos T CD4 y lesiones bucales de portadores del VIH/sida / Association between CD4 T lymphocyte levels and oral lesions in HIV/AIDS patients

Introducción: Las enfermedades de la cavidad bucal en los pacientes con VIH/sida pueden verse agravadas dependiendo de la respuesta inmunitaria del paciente y los niveles de linfocitos. Objetivo: Relacionar los niveles de linfocitos T CD4 y las principales lesiones bucales en pacientes con el VIH/sida del Hospital Nacional Hipólito Unanue (Lima, Perú), durante el 2018. Métodos: Se realizó un estudio analítico y de corte transversal, entre julio y octubre del 2018, en 65 pacientes hospitalizados, a los cuales se realizó un examen clínico de la cavidad bucal. Se evaluó la presencia de manifestaciones bucales asociadas al VIH/sida; también se clasificó el nivel de linfocitos T CD4 en tres categorías (> 500 cel/mm3, entre 200-500 cel/mm3 y < 200 cel/mm3). Resultados: Un 70,8 por ciento de los pacientes no se encontraba con tratamiento antirretroviral al momento del examen. El nivel promedio de linfocitos T CD4 fue 237,65 cel/mm3, con mayor prevalencia en mujeres. El 56,9 por ciento de los pacientes presentaron lesiones bucales, el sexo masculino fue el más afectado (91 por ciento). La lesión más frecuente fue la candidiasis bucal (44,6 por ciento) y la categoría que presentó mayor frecuencia de lesiones bucales fue la < 200 cel/mm3 (38,5 por ciento; p < 0,05). Conclusiones: El sexo masculino presentó la mayor cantidad de lesiones bucales asociadas a bajos niveles de linfocitos T CD4. La mayor parte de lesiones bucales se presentaron en un nivel de linfocitos T CD4 < 200 cel/mm3. La candidiasis bucal fue la lesión que más se evidenció al momento de realizar el examen clínico(AU)

Introduction: Oral diseases may be aggravated in HIV/AIDS patients depending on their immune response and lymphocyte levels. Objective: Describe the relationship between CD4 T lymphocyte levels and the main oral lesions in HIV/AIDS patients from Hipólito Unanue National Hospital in Lima, Peru, during the year 2018. Methods: An analytical cross-sectional study was conducted of 65 hospitalized patients from July to October 2018. The patients underwent oral clinical examination. Evaluation was performed of the presence of HIV/AIDS-related oral manifestations, and CD4 T lymphocyte levels were classified into three categories: > 500 cell/mm3, 200-500 cell/mm3 and < 200 cell/lmm3. Results: Of the total patients studied, 70.8 percent were not under antiretroviral treatment at the moment of the examination. Average CD4 T lymphocyte level was 237.65 cell/mm3, with higher results among women. 56.9 percent of the patients had oral lesions. Males were more commonly affected (91 percent). The most frequent lesion type was oral candidiasis (44.6 percent), whereas the category presenting the highest frequency of oral lesions was < 200 cell/mm3 (38.5 percent; p < 0.05). Conclusions: Male patients presented the largest number of oral lesions associated to low CD4 T lymphocyte levels. Most of the oral lesions were found at a CD4 T lymphocyte level < 200 cell/mm3. Oral candidiasis was the lesion most commonly found by the clinical examination(AU)

Exéresis de odontoma complejo mediante osteotomía sagital de rama. Reporte de un caso / Surgical excision of a complex odontoma via sagittal osteotomy of the mandible. A case report

El odontoma es un tumor benigno originado a partir de una alteración de células odon- togénicas epiteliales y mesenquimatosas diferenciadas con capacidad de formar esmalte, dentina y cemento, siendo la diferencia entre ambos la organización del tejido dentario. La etiología es desconocida pero se ha asociado a infecciones, anomalías hereditarias, hiperactividad odontoblástica y traumatismos. Cuando el odontoma es de tamaño pe- queño o promedio, el tratamiento aceptable es la exéresis del tumor. El problema surge con los odontomas grandes, cuya extirpación implica el sacrificio de grandes cantidades de hueso, el potencial de fractura mandibular y el daño del nervio alveolar inferior. Para evitar estas complicaciones en la extirpación de tumores grandes en la mandíbula, Ritter- sma y van Gool introdujeron en 1979 el uso de la técnica de osteotomía sagital de rama mandibular para tratar esta patología. Se reporta el caso de un paciente varón de 37 años, sin antecedentes sistémicos, que presentó aumento de volumen de hemicara izquierda asociado a dolor y secreción purulenta, se realizó los exámenes clínicos, imagenológico e histopatológicos, llegando al diagnóstico de odontoma complejo infectado. Fue tratado con la técnica osteotomía sagital de rama mandibular exitosamente en el servicio de ciru- gía bucal y maxilofacial del Hospital Nacional Hipólito Unanue, Lima-Perú

The odontoma is a benign tumor that comes from an alteration of differentiated epithe- lial and mesenchymal odontogenic cells capable of forming enamel, dentin and cement. The etiology is unknown, but it has been associated with infections, inherited abnorma- lities, odontoblastic hyperactivity and trauma. To small or average odontoma size, the acceptable treatment is tumor exeresis. The problem arises with large odontomas, whose removal involves the sacrifice of large amounts of bone, the potential for mandibular fracture and damage to the inferior alveolar nerve. To avoid these treatment complica- tions, Rittersma and Van Gool introduced in 1979 the use of the sagittal-cut osteotomy technique of mandibular ramus. We report the case of a 37-year-old male patient, with no contributory systemic history, who presented increased volume of left side face asso- ciated with pain and purulent secretion; clinical, imaging and histopathological exami- nations were performed, arriving at the diagnosis of infected complex odontoma. It was successfully treated via sagittal osteotomy technique of the mandibular ramus at Hipólito Unanue Hospital ́s Oral and Maxillofacial Surgery Service, Lima-Peru
