ABSTRACT
RESUMEN: La higiene oral es fundamental en pacientes en tratamiento de ortodoncia. Actualmente hay una oferta amplia de cepillos eléctricos con este fin. El objetivo del presente estudio, fue determinar la eficacia y la comodidad del cep illo eléctrico Oral-B® Professional Care 500 en pacientes portadores de ortodoncia. Se realizó un ensayo clínico, randomizado, doble ciego, unicéntrico, con una muestra de 90 pacientes, divididos en dos grupos: 45 pacientes utilizaron cepillo eléctrico y 45 sujetos utilizaron cepillos manuales durante 90 días. Se determinó la efectividad con los índices O'leary, índice de placa de bracket e índice de Eastman al inicio, a los 30 y a los 90 días de uso de los cepillos y se evaluó la comodidad del cepillo eléctrico mediante una encuesta de satisfacción al término del estudio. Al analizar los datos, se observó una disminución significativa en los índices de O'leary y de placa de bracket en ambos grupos,mientras que se observó una disminución significativa en el índice de Eastman sólo en el grupo que utilizó el cepillo eléctrico. El resultado de la encuesta, indica qu e, en opinión de los participantes del estudio, el cepillo eléctrico es cómodo, fácil de usar y recomendable para pacientes con aparatología fija. En conclusión, el cepillo eléctrico Oral-B® Professional Care 500 resultó ser efectivo y cómodo al ser usado por pacientes portadores de ortodoncia fija y puede ser recomendado para este tipo de pacientes.
ABSTRACT: Oral hygiene is essential in patients undergoing orthodontic treatment. Currently there is a wide offer of electric brushes for this purpose. The objective of this study is to determine the efficacy and comfort of the Oral-B® Professional Care 500 electric toothbrush in orthodontic wearers. A double-blind, single-center clinical trial was carried out, in which the sample was 90 patients, these were randomized into two groups: 45 patients with electric toothbrush treatment and 45 subjects with manual toothbrush treatment. The effectiveness was determined with the O'leary indexes, the bracket plate index and the Eastman index. For the evaluation of comfort, a survey was used. Statistical analysis was performed with the Shapiro-Wilks test and the Mann-Whitney U test, in which a significant decrease was found in the O'leary index and bracket plate index in the group that used the electro-oscillating brush rotary and a greater decrease in the Eastman index was observed in the same group. In conclusion, the electric toothbrush is comfortable and easy to use, recommended for patients with fixed appliances.

OBJECTIVE: The objective of this study is to assess the relationship between centric relation-intercuspal position discrepancy (CR-ICP discrepancy) and temporomandibular disorders (TMDs), by systematically reviewing the literature. MATERIALS AND METHODS: A systematic research was performed between 1960 and 2016 based on electronic databases: PubMed, Cochrane Library, Medline, Embase, Scopus, EBSCOhost, BIREME, Lilacs and Scielo, including all languages. Analytical observational clinical studies were identified. Two independent authors selected the articles. PICO format was used to analyze the studies. The Newcastle-Ottawa Scale (NOS) was used to verify the quality of the evidence. RESULTS: Four hundred and sixty-seven potentially eligible articles were identified. Twenty studies were analyzed, being grouped according to intervention in studies in orthodontic patients (n = 3) and studies in subjects without intervention (n = 17). Quality of evidence was low, with an average score of 3.36 according to Newcastle-Ottawa Scale. In most studies, the presence of CR-ICP discrepancy is associated with the presence of muscle (pain) and joint disorders (noise, disc displacement, pain, crepitus, osteoarthritis and osteoarthrosis). However, the lack of consistency of the results reported reduces the validity of the studies making it impossible to draw any definite conclusions. CONCLUSIONS: Because of the heterogeneity of the design and methodology and the low quality of the articles reviewed, it is not possible to establish an association between CR-ICP discrepancy and TMD. The consequence of CR-ICP discrepancy on the presence of TMD requires further research, well-defined and validated diagnostic criteria and rigorous scientific methodologies. Longitudinal studies are needed to identify CR-ICP discrepancy as a possible risk factor for the presence of TMD.
