ABSTRACT

El objetivo más importante de la investigación fue demostrar la eficacia de los sonidos binaurales en la consulta dental como técnica actual para disminuir la ansiedad de los pacientes con parálisis cerebral infantil, así como comprobar que el entorno odontológico genera temor en los pacientes pediátricos. Por medio de un oxímetro de pulso, un aparato reproductor mp3 y auriculares, se logró cuantificar las pulsaciones cardíacas durante tres momentos a lo largo de la investigación. Se valoraron las historias médicas de cada uno de los niños del Hogar Divina Misericordia, así como los medicamentos que consumen diariamente y las enfermedades asociadas a la parálisis cerebral. Se observaron diversos tipos de reacciones al utilizar cada uno de los sonidos, desde el llanto y enojo hasta conseguir la tranquilidad y alegría en los pacientes. Finalmente los resultados revelan los beneficios y la veracidad de los sonidos binaurales mientras que, por el contrario, se expone a los sonidos del ambiente odontológico como un método distractor y desfavorable durante las visitas dentales.


The most important objective of the research was to demonstrate the efficiency of binaural beats in the dental consultant as a current technique to reduce anxiety in child patients with cerebral palsy, also prove that the dental environment generates fear in pediatric patients. To achieve quantify the heartbeats of the children during three different moments throughout the investigation, we used fingertip pulse oximeter, a mp3 player and headphones. We evaluate the medical histories of each children from Hogar Divina Misericordia, as well the medicines they consume daily and diseases related with cerebral palsy. We observed different types of reactions when using each of the sounds, some cried and got anger until they get relax and happy. Finally the results in this research show the benefits and the veracity of the binaural beats while on the contrary are expose to the sounds of the dental environment as a distracting and unfavorable method during dental visits.

ABSTRACT

En odontología estamos expuestos a muchos microorganismos por la producción de aerosoles. Por ello es esencial conocer la naturaleza de éstos y su potencial patogénico. El objetivo de esta investigación es determinar contaminación bacteriana, generada por aerosoles durante procedimientos odontológicos, con uso de pieza de mano de alta velocidad, realizados por alumnos de la carrera, en Clínica Odontológica Docente Asistencial (CODA), Universidad de La Frontera, Temuco, Chile. Estudio con muestra aleatoria, de 16 de un total de 32 unidades dentales, estratificado por box, con 40 muestras, ocho placas control y 32 placas prueba. El medio de cultivo, se mantuvo por diez minutos, donde se realizaron acciones de operatoria con turbina, bajo aislamiento absoluto, ubicadas en frente del operador y pechera del paciente. Las muestras fueron analizadas microscópicamente, incubadas a 37°C en atmósfera de oxígeno por 24 horas y dióxido de carbono a las 48 horas. Treinta y dos placas prueba fueron positivas, registrándose diversidad de crecimiento bacteriano, promedio 58,874 Unidad Formadora de Colonias (UFC) por unidad dental. El mayor porcentaje de microorganismos fueron: Bacillus spp. (28,56%) y Bacilos Gram positivos (24,31%). Siete placas control resultaron negativas y una con 3 UFC de Micrococcus spp. La mayoría de los microorganismos encontrados son comensales potencialmente patógenos. Al comprobar que los aerosoles constituyen una fuente importante de emisión de microorganismos, se hace imprescindible cumplir con todas las normas de bioseguridad que protegen tanto al operador como al paciente


In dental practice we are exposed to many microorganisms due to aerosol production. It is essential to be aware of the nature of these elements and their pathogenic potential. The purpose of this research is to determine the presence of bacterial contamination in aerosols produced during dental procedures that require the use of a high speed dental handpiece. These dental procedures were carried out by dentistry students at the dental clinic of the Universidad de La Frontera. In order to determine the presence of bacteria in aerosols, cultivation plates were used. A total of 40 samples were taken from 16 dentistry students while performing dental procedures that required the use of a high speed dental handpiece in conditions of complete isolation. Eight control plates and 32 test plates were used. Two selected areas were examined: operator´s front andpatient´s chest protector, during 10 minutes. The samples were then taken to the laboratory and incubated in an oxygen atmosphere for 24 hours and subsequently in carbon dioxide for another 24 hours at a temperature of 37 degrees Celsius. Finally the samples were microscopically analyzed. Seven control plates showed no bacterial contaminants and one showed 3UFC of Micrococcus spp. The 32 test plates were found to be positive showing diverse bacterial growth (58.874 UFC average per subject). The highest percentage of microorganisms was constituted by Bacillus spp. (28.56 %) and Bacillus Grampositivos (24.31 %), representing more than 50% of the total. The majority of the microorganisms found belong to the commensal family, although they can change into opportunistic pathogen microorganisms. Verifying that aerosols are an important source of emission of microorganisms, it is essential to comply with all biosecurity standards in order to protect the operator as well as the patient
