An educational program on oral health prevention with a strong component based on playful strategy was developed for 28 children, 7 - 9 year olds from the Andrés Razuri school of San Martin de Porres district. The level of knowledge of the children was evaluated before and after the intervention showing that before no one recognized dental caries as a disease, after receiving the pertinent information, 37 % of them did, and 67 % can recognize 4 factors that generate them. They recognize 3 basic hygienic basic elements which changed from 46.4 % to 88 %, the concept of the moments of tooth brushing was changed so that they associated them with the ingestion of food of 17.9 % to 56 %, the identification of seals as a preventive element varied from 28 % to 74 %, then we conclude that the levels of knowledge were inverted by the efficiency of the proposed strategies, reaffirming that the edu...

The purpose of this study was to evaluate academic stress and its impact in the academic performance of students of dentistry.

The aim of this study was to evaluate retrospectively the risk factors for cleft lip and/or palate. It was selected a sample of 45 children with a cleft lip and/or palate and 45 healthy newborns at Mother Child National Teaching San Bartolome Hospital from January 2000 to December 2009 and their respective biological mother to assess retrospectively the conditions under which this was formed during the first trimester of pregnancy. It was found that the prevalence of cleft lip and/or palate was 0,17 % ie, 1,7 per thousand live births. The male gender (RRI 1.7), maternal age (RRI18.4; RRI23,9), family history of cleft lip and/or palate (RRI 3,3), number of previous pregnancies (RRI1 4,6; RRI2 1,1) are risks factors. The history of infections, radiation and medication during the first trimester of pregnancy were not found to be risks factors.

Introduction: Platelet-rich plasma (PRP) is a biomaterial with a high platelets concentration and growth factors enhance tissue regeneration after application in surgical procedures, such as third molar extraction. Material and methods: The study was performed with 20 patients with indication for third bilateral lower molar extraction. The extraction were performed in the same surgical time and one of them the PRP gel was applied (randomly chose) and the other as control group. The postoperative evaluation was carried out until three and a half months, the parameters evaluated were: postoperative pain and wound and bone density using Cone Beam computed tomography. Results: Postoperative pain during the third day, first and second week was lower grade than sites of PRP application to the control group (p <0.05). The bone density measured by Cone Beam CT was higher at the sites of PRP a...

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.
