It is demonstrated the efforts made endodontic microbiology and science to get to decipher the secrets of this unique structure although every day new questions arise. We need the treatments we use to combat biofilm achieve oxygenate the periapical ecosystem and basically scrape and loosen the tightly adhering bacteria Knowing the process of biofilm formation, microbial metabolism and strategies that they use to resist and remain hidden but active , we know why we observe refractory periapical lesions.

It was evaluated the weight and height of 101 children, 3 to 5 year-old, from the marginal urban area "Playa Rimac " of Lima city, to determine their nutrition state, and know the influence that can exist with d.m.f. Index. There was 1% of children with malnutrition "moderate", 15% with malnutrition "light", 72% nutritional state "normal", and 12% in state of "obesity", no one with "severe" malnutrition. The mean d.m,f Index was 4,7 even arriving at 6,6, although it showed the tendency to be elevated in cases of malnutrition, there was not a positive statistical correlationy as it happened to Oral Hygiene Index, since 61 % qfthe children presented a high level of plaque.

The purpose of the present study was to compare the dental caries experience and treatment needs of 678 school children, from 6 to 12 years old, belonging to a urban school and a marginal urban school of Lima city. The data was recorded using OMS codes for Oral Health Surveys. It was determined that urban school children are 5,5 % caries free and marginal urban school children 2,3 % caries free. The greatest significative c. p. o. index was in 6 year old students from the urban marginal zone (7,64) than students from the urban zone (6,17). The greatest c. p. o. index was in 12 year old students from the urban marginal zone (5,66) than students from the urban zone (5, 70). Treatment needs for dental caries are significantly greater (6.47 teeth) for marginal urban children than urban ones (5,47 teeth). ONE SURFACE FILLING was the major treatment required reaching 50 % of total needs, TWO O...

In order to conduct this study were selected 100 patients from the clinics consult devices of the Odontology School of the UMSM and from the Odontopediathrics Departament of the Instituto Nacional del Niño from to 8 to 10 years old, presence of dental caries in both half dental arcades without any other systemic pathology associated. With the permission of the parents or the personal in charge of the patient, we proceed to fill the odontogram and initiate the Non Traumatic Restoration Treatment (NTRT) according to the protocol: Caries within half dental arcade without chemical-mechanical caries tissue remotion and with standard odontological treatment (group A) and caries within the left half dental arcade with chemical-mechanical caries tissue remotion using CARISOLV according to the manufacturer specifications (group B). The dental final restorations were planned to be perfomed with g...

Lepidium peruviam (Maca), is a tuber with excellent nutritional and medicinal qualities due to its mineral and chemical compounds: vitamins, proteins, fatty acids, carbohydrates, tannins, and alkaloids. Method. This experimenta1 study aimed to determine the effect of Maca in the development of sex cells in mammals. The study conducted in 20 young Holtzman rats divided into two samples, in the experimental one rats consumed two grams of Maca daily for 30 days. Animals were sacrificed and then they were dissected; samples were histological studied. Results and conclusions. We noted that the use of Maca was very effective in the development of Sertoli and Leydig cells, and quite effective in spermatocytes development.

To evaluate the impact of the international accreditation process at Universidad Nacional Mayor de San Marcos’s Faculty of Dentistry was the purpose of the investigation. Methodology: The study was descriptive, cross-sectional and retrospective. The sample was made up by 307 (of 450) students randomly selected. The data collection was obtained by a questionnaire survey. Chi square test (SPSS 20) was applied. The results showed that the level of student’s satisfaction related to accreditation process was regular to good (37.1% and 51.3%). About the dimensions of coherence of the achievements the purposes: relevance, integrity and effectiveness were considered as good 74.9% (p = 0.004); about the availability, efficiency and effectiveness of resources as regular 50.2% and good 34.2% (p = 0.00); with regard to changes in the process: mode of operation of the organizational structures an...

The aim of this study was to determine the correlation between hypo-salivation and corono-radicular caries in older adult patients, which analyzed the physicochemical properties of saliva (flow, pH), the frequency and location of the corono-radicular caries. Was selected a sample of 45 persons, adult patients over 60 years and another 18 to 26 years (control group), from service centers, hospitals and universities. The technique of collection of saliva, consisted of making chewing a piece of paraffin for a period of five minutes and gradually spit in a tank, which allowed to measure the volume and pH salival. We observed the oral higiene and the corono-radicular caries of all tooth surfaces. The results, the volume of saliva in the elderly, had an average of 3.27 ml/5min very low values compared with the values of young people who have an average of 5.22 ml/5min. It was found that 98 % o...

The purpose was to relate the level of knowledge, biocontaminated waste management. and the level of pollution generated in two Dental Clinics: Clinicof the Faculty of Dentistry at the National University of San Marcos (San Marcos) and the Universidad Nacional Federico Villarreal (UNFV). The type of study was cross-sectional l. Attended by 299 people including students, teachers and maintenance staff. Was used an observation sheet and microbiological analysis. There was a low and very low level of staff knowledge about biocontaminated Waste Management. There were no gender differences in UNMSM staff (p = 0.55), while in UNFV, males showed less knowledge (p = 0.038). The biocontaminated and pathologic waste management from generation to final disposal is inadequate (UNMSM 92.3 % and 58.5 %, 100.0 % and 51.8 %UNFV respectively). The handling of needles is adequate (77.4 % UNMSM, UNFV 100 %...

The aim of this study was to determine the level of knowledge on oral health of mothers and their relationship with oral health status of their children under five years old, who were admitted to hospitals of Ministry of Health (MINSA) and Social Security (ESSALUD). Were taken into consideration ethical standards. This is an analytical and cross-sectional study. The sample consisted of mothers with children under five years of age (n 143). Was used not randomized quota sampling. Was applied a structured questionnaire to collect information about the level of mother´s knowledge on oral health and a diagnostic sheet for oral health status of children under five. Clinical examination was performed with artifitial light, using epidemiological indices: Dental Caries Index (dmft), and the Simplified Oral Hygiene Index by Greene-Vermillion (OHI-S). There was no significant association between ...

One of the aims of a root-end filling material placed in an apicectomy treatment is to provide apical seal that can inhibits the coronary migration of antigens to perirradicular tissues. Many materials are used for this end; however, to date there has not been any material that satisfies all the requirements of an ideal material. With the purpose of making a comparative analysis of the apical sealing abilities of three root-end filling materials: silver amalgam, glass ionomer and MTA (mineral trioxide aggregate), in the leakage process of Enterococcus Faecalis bacteria and the time used for it to leak via coronary toward the perirradicular area, the present investigation was made. Leakage was proven when veering the fenol red glucose, in which the apexes of the sample teeth were submerged, to a temperature of 37ºC. The results showed that specimens that leakage in longer than 70 days we...
