La Artrocentesis de la articulación temporomandibular (ATM) es una alternativa de tratamiento eficaz; mínimamente invasiva para la abertura bucal limitada debido al desarreglo interno discal irreductible o al deterioro de las estructuras de la ATM que producen artralgia severa que no cede con tratamientos conservadores. Se presenta un caso clínico de una paciente con limitación de abertura y dolor orofacial intenso que se soluciono satisfactoriamente con lavaje articular con un nuevo dispositivo de una sola punción. Se mejora la abertura bucal con el consiguiente alivio del dolor y satisfacción del paciente en una sola sesión. Utilizando este dispositivo, no se requiere la inserción de dos agujas; lo que facilita, el procedimiento y lo hace menos invasivo.

The tissue adhesive based on cyanoacrylate monomers created by their investigators for the synthesis of recent surgical or traumatic wounds, has had a really extensive use in skin wounds treatment. In this investigation the cyanoacrylate is evaluated in the synthesis of mucoperiostal flaps in the buccal cavity comparing with the use of conventional silk suture 3/0. For this reason 20 patients of the Central Clinic Surgery Service of our Dentistry Faculty, who were going to have a surgical intervention for the extraction of impacted teeth, were selected, the mucoperiostal flaps synthesis were made using both methods. From the wound healing evolution observation in a period of 14 days we reached the following conclusions: 1) the use of butyl cyanoacrylate as a mean of confrontation of mucoperiostal flaps basically diminished the operative time of placement, virtually painless method since ...

This clinical case report presents the sequence of surgical treatment of a dentigerous cyst and intraoperative complication of displacement of the tooth within the cyst. The dentigerous cyst is the second most common odontogenic cyst. It is generally associated with the crown of an impacted normal tooth, usually with lower third molars and maxillary canines. One of the surgical treatment (enucleation) of the cysts is indicated in cases where complete removal of pathological tissue is required and even removal of the teeth involving odontogenic cysts; however, if treatment is not done they can become other dental pathologies involving adjacent pieces to injury. Clinical sequence of surgical approach is presented for extracting a tooth associated with a dentigerous cyst.

To carry out this investigation, eight patients 15 to 21 years old of Central Clinic of UNMSM Dentistry Faculty who had the indication for. first permanent molar extraction and at the same time had a third molar germ in eruption, were selected. The germ was at least in a Nolla development stage 7, 8 ó 9. Having the patient´s respective consent they underwent the autotransplantation of the germ to the socket of the first molar within the same quadrant. Cases were followed for a 12 weeks period. DIfferent tests to determine J the donor tooth was vital or not, were done. Six weeks after transplantation a high percentage of teeth began to respond to thermal and electric pu1p tests, the mobility they initially presented diminishing gradually. Until the time lapsed, the transplanted teeth clinically appeared to become firmer and conserved their pulp vitality. Being 70 to 80% of teeth that ma...

Para llevar a cabo la presente investigación se seleccionaron ocho pacientes de la Clínica Central de la Facultad de Odontología, de 15 a 21 años de edad, que tenían la indicación para extracción de la primera molar permanente, y a la vez, poseían el germen de la tercera molar del mismo cuadrante en erupción, cuya raíz se encontraba por lo menos en un estadío Nolla de 7, 8 ó 9. Teniendo el consentimiento respectivo del paciente se realizó el transplante autógeno del germen al alvéolo del primer molar. En el post operatorio se hizo el seguimiento de los casos hasta un período de 12 semanas, realizando diferentes pruebas para determinar si el diente donante se encontraba vital o no. A partir de la 6ta semana del post operatorio, un alto porcentaje de los dientes transplantados empezaron a dar respuestas de vitalidad pulpar a las pruebas térmicas y a la prueba eléctrica, d...

The purpose of this study was to evaluate the solubility of gutta-percha in three solvents used in endodontics: xylol of traditional use, and the essential oils: eucalyptol and orange oil, of recent use, given the frequent need to remove the obturation material in radicular retreatment procedures. One hundred twenty samples of gutta-percha were prepared in a standardized way in small cylinders, being divided equally into four groups for immersion in three experimental solvents and distilled water (control group) during 2.5 and 10 minutes at room temperature. The solvent effect was recorded in grams of weight loss, calculating the difference between pre and post-immersion samples weight for each experimental time. The results were analyzed and compared by Tukey test (p <0.05). Under the conditions of this study it is concluded that, all experimental solvents were effective to dissolve ...

The purpose of the investigation was, to compare the marginal seal of direct restorations, carried out with the sandwich technique, after the removal of decayed tissue by means of papaine gel (Papacarie) and the conventional rotational method. So, 20 recently extracted human premolars were selected, with decay lesions that committed the oclusal and proximal surface. The sample was randomly divided in two groups: Group 1: the removal of decayed dentine was made, by means of the chemo mechanical technique using the gel Papacarie. Group 2: the removal of decayed dentine was made by means of the conventional technique, using rotational instruments. After the removal of decayed tissues by both techniques a direct restoration was placed using the sandwich technique, placement of glass ionomer modified by resin, adhesive system of a single step and micro hybrid composite resin. Then, after term...

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 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 ...
