Saliva is an etiological factor of caries. It acts stabilizing pH by its concentration of carbonates and phosphates. When the oral hygiene is deficient, pH becomes acid and optimal for the demineralization of teeth surfaces. If a diet rich in sugars and flour predominates, they become more acid and the risk of caries beginning is imminent. To determinate the behavior of salivary pH and demonstrate the effectiveness of the brushing as a low cost, efficient, easy application prevention measure, in children with cariogenic risk, samples of saliva of 44 children between 6 and 8 were taken, from San Martin de Porres district, before and after breakfast and analyzed with a potentiometer. GROUP 1: with old bacterial plaque (without previous tooth brashing) and GROUP 2: with recent bacterial plaque (with previous tooth brushing). According to “t” test analysis, the variation of pH salivary i...

It was determined the effect on the attitude for preserving the buccal health of male and female children of 8 and 9 year old; with two didactic methods, one based on game of rules nominated DENTOPLAY and the other, expositive method for an expert using scale models and posters. There were 8 sessions, one per week, each one lasted 45 minutes, the topics were similar for both groups. It was established the attitude for three components, cognitive (knowledge and believes) with four indicators, accessibility, importance and maintenance of the buccal health, dental decay; affective about nutritious preferences, self care, dentist’s image, motivation, self confidence, spokesman of buccal health in family environment; and the volitional one conformed by participation, attention and children’s concentration. The Oral Hygiene was evaluated before and after the experience. The results showed ...

Existiendo dificultades en la rápida identificación de la magnitud de afectación de fluorosis en muchas zonas con contenido natural de fluoruro en el agua, especificamente con referencia al monitoreo y modulación de programas de fluoruración por vía sistémica, el presente estudio se planteó como objetivo de determinar la pieza dentaria afectada con fluorosis y aquella que presenta mayor correlación con el nivel de afectación general en una localidad. Para ellos se realizó el estudio en una población del departamento de Ayacucho; cuyo contenido de agua de consumo humano fue de 1.5 ppin, valorado mediante el método de electrodo especifico con el empleo de un potenciometro de rango de sensibilidad de 10 marca Orion modelo 720A. La evaluación abarcó piezas dentarias afectadas seleccionadas considerando por lo menos uno de cada grupo refiriéndonos a los incisivos, caninos, pre...

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 ...

Periodontal diseases after dental caries are the most prevalent in the dental health is concerned. The gingivitis and periodontitis are the result of the presence of bacteria and their products capable of altering the tissue and the host response. Studies on action of Camellia sinensis (green tea) on microorganisms of periodontal disease, demonstrates the beneficial effects of this product and the application potential in different areas. Therefore the purpose of the study was to determine the in vivo effectiveness of a gel made from carboximetilcelulosa and alcoholic extract of green tea, and in vitro on microorganisms associated with periodontal disease: P. loeschi, P.anaerobius and Capnocytophaga. The results show the presence of halos of inhibition of green tea extract at concentrations of 100 %, 75 %, 50 % and 25 %, the gel was observed only action on the site of contact, no halo. R...

Las enfermedades periodontales después de la caries dental, son los problemas más prevalentes en lo que a salud bucal se refiere. La gingivits y la periodontitis son resultados de la presencia de las bacterias y sus productos capaces de alterar los tejidos así como de la respuesta del hospedero. Diversos estudios se han desarrollado utilizando productos naturales en el país, por ejemplo, la uña de gato, muña, propóleo, coca, el té verde comprobándose su acción antimicrobiana y en este ultimo caso también acción anticancerígena.

The objective of this research was to determine the personal, academic and administrative factors that influence to obtain the academic degree of Dentristy Master in San Marcos National University for which we selected two groups of graduated without degree and graduated one. They were located personaly or by mail using a self-administered instrument. Was used the nonparametric test chi square. Relationship was found mainly with academics aspects as experience in the research area and the fact of being prepared for the development of a research project, have been responsible for a research project, having been participated as adviser or thesis project reviewer, having been published and carry out teaching, also administrative aspects due to the lack of administrative paperwork way and difficulties of acceptance from the institution where the work should be developed, finding no relation ...

With the purpose of determinate the antimicrobial activity of the Papacarie® in the time indicated by the manufacturer (30seconds), samples were taken from caused to decay weave of temporary pieces without commitment to pulpar of five children of the school Andrés Rázuri, to analyze in vitro the sample with the product. Taking into account that the product requires to be in contact with the sample a short time, discs with the Papacarie® became absorbed and faced this by 15, 30 and 60 seconds, the discs were retired and the sample in Agar Mitis Salivarius Bacitracina was seeded. The obtained counts of the controls made to 24, 48 and 72 hours, were analyzed with T Student statistical analysis. The results demonstrated that with the used methodology a significant difference between the antimicrobial activity and the indicated application times does not exist.
