In order to determine, the antimicrobial effect in vitro of solutions of Camellia sinensis (green tea) of four commercial products (A, B, C and D), we recolected not stimulated saliva of 40 university students and cultivated them in Tripticase soy Agar using Assay disc diffusion for the tea solutions, (Amoxilicina) as a positive control group and (distilled water) as a negative control group, plates were incubated to 37 °C/24 hours. The same procedure was performed for S. mutans ATCC 25175. According to results, all commercial products of green tea produced inhibition of zones of growth colonies. The statistical analysis of four commercial products of tea determined that significant differences between medias of the samples exists. Comparing couples of medias, it shows the existence of significant differences to level of 0.05 between couples of marks AB; AC; BD; CD. The analysis of samp...

Con el objeto de determinar, el efecto antimicrobiano in vitro de soluciones de Camellia sinensis (te verde) de cuatro marcas comerciales (A,B,C y D), se recolectó saliva no estimulada de 40 estudiantes universitarios y se sembró en el medio de Agar Tripticasa soya. Utilizándose el metodo de difusión por discos para las soluciones de té y los controles positivos (Amoxicilina) y negativo (agua destilada), las placas se incubaron a 37 °C /24 horas. Igual procedimiento se realizó con la Cepa de S. mutans ATCC 25175. De acuerdo a los resultados las cuatro marcas de té verde produjeron halos de inhibición de crecimiento de colonias. El análisis estadístico de las cuatro marcas de té determinó que existía diferencias significativas entre las medias de las muestras. Comparando pares de medias, resultó la existencia de diferencias significativas a nivel de 0.05 entre pares de marc...

The objective of the present study was to evaluate and compare the effect of Iidocaine and mepivacaine alone and associated with epinephrine on the cardiovascular and electrocardiographic parameters,60 healthy volunteers were assigned in 4 groups: A (2% lidocaine), B (2% lidocaine with epinephrine 1: 100,000); C (3% mepivacaine), D (mepivacaine 2% with epinephrine 1: 100,000). Therefore of assigned, it was injected ldental cartridge of correspondent anesthetic to each volunteer, using the nerve block anesthesia technique for the inferior mandibular nerve. In each patient was performed the measure of the heart rate, blood pressure and electrocardiogram. These measurements were carried out 5 minutes before and then 15 after minutes the administration of local anesthetic. The participants of the lidocaine 2% without vasoconstrictor group showed decline in the indicator heart rate (p <0.0...

Surgical antibiotic prophylaxis consists in the use of an antimicrobial drug in a preventive way, that must be active against microorganisms that in high frequency causes posterior infections of our surgical wounds and maintain effective tissue concentrations along the surgery procedure and the posterior time when appears the bacteremia. To reach a successful treatment is necessary to have the knowledge of the resident bactemial flora and the pathogenous flora that infects our surgical wounds. We must choose the correct antibiotic and use it by the correct time. Generally, that time does not exceed 24 hours and in the prophylactic schemes are used some antimicrobial drugs like beta-lactams, azalides lyncosamides and aminoglycosides, that must be selected depending of the medical condition of the patient and some topic related directly with the surgical technique employed.

The presence of adverse drug reactions with local anesthetics takes us to the search of effective alternatives to this drugs. 60 albino rabbits divided into 6 groups were submifted to infiltrative anesthetic technique in the maxilla with lidocaine, mepivacaine, bupivacaine, chlorpheniramine and dimenhidrinate, in front of sodium chloride 0,9%. The pain threshold belzavior was evaluated with electrical stimulation from Ruhnkorff s bobbin behind the drllg application and comparison between groups was made. The wlzite llsed drugs elevated the pain threshold, with a better response of lidocaine. Both local anesthetics and antihistamine drugs produced an effective local anesthesia, without tissue damage.

In order to determine, in vivo antimicrobial effect of Camellia sinensis infusión (green Tea), as a mouthwash at 10 %; not stimulated saliva of 32 seemingly healthy people was collected: 1) Before mouthwash, 2) immediately after, and 3) after 30 minutes. The samples were spread in Agar Tripticasa Soy Bean and Agar Mitis Salivarius Bacitracina; then proceeded to the recount of the forming units of colonies of Mutans Streptococci for mL: The statistical analysis of results, by means of “t” and Wilcoxon tests, indicate that significant differences exists. On the other hand in the analysis of the mouthwash to determine polyphenols presence, by means of the infrared spectrophotometry peaks transmitted in wave lengths for the oxydril groups (-0H) and aromatic ring were observed. One concludes that there is an effective reduction in the number of microorganisms of the mixed salivary micro ...

The aim of this study was to demonstrate that the use of irrigating solutions in surgical procedures does not alter both inflammation processes and tissue repair. Four (04) groups were formed containing 15 rats each. After being dosed with general anaesthesia, they underwent osteotomy in the tibia with tungsten carbide burs and irrigation for 15 seconds, using the following solutions in each group: A) 0,12 % chlorhexidine with cetylpyridinium 0,05 %, B) 0,12 % chlorhexidine with aspartame; C) hexetidine 0,1 %; D) 0,9 % sodium chloride. After 3, 7 and 15 days of surgery, the rats were sacrificed and tissue samples were removed for histopathological analysis. The results showed that groups in which chlorhexidine with cetylpyridinium, and chlorhexidine with aspartame were used, less inflammatory process were found than in groups of sodium chloride and hexetidine. On the process of tissue re...

The aim of the study was to evaluate the possible modifications in the arterial pressure, corporal weigh and creatinine cleareance in urine gathered during 24 hours, in healthy young people, under therapy with two non steroidal anti inflammatory drugs (NSAID’s); one of them not selective to Ciclooxigenase (Ibuprofen) and a selective inhibitor of Ciclooxigenase - 2 (Celecoxib), during three days in standardized dose, in comparison with a control group that was administered placebo, in a double blind study. The results indicate that there are not statistically significant differences among the three groups, for the clinical and laboratory evaluated parameters (p <0,05). We conclude that a short term therapy with the used NSAID’s doesn’t produce clinical impact modifications in the arterial pressure, corporal weigh and creatinine cleareance in urine gathered during 24 hours.

The aim of this study was to compare two antibiotic prophylaxis regimens with Clindamycin in patients under semi-retained third lower molar surgery. Third molar extractions were carried out in healthy patients who complied with the inclusion criteria, in the central clinic surgery service of San Marcos University dentistry faculty. After having performed the exodontia control appointments were programmed during 5 days post – extraction where the infection signs were evaluated through the presence or bleeding or exudates on the surgical bed. This registration was carried out for both groups. The obtained data was analyzed using the Mann-Whitney U test (p <0.05). A significant difference was not found in the proportion of cases infected among the groups. However, the results showed a smaller quantity of patients with infection in the group of the intramuscular via (10%) in relation wi...
