“…La variable de higiene bucal se recolectó mediante el Índice Cuantificado de Placa (ICP) tomado antes y después de cada uno de los cuatro controles. 16 De igual manera, se incluyó la variable deterioro de cepillo que se midió por medio del índice de Rawls y colaboradores el cual determina el nivel de dispersión y el desgaste de las cerdas del cepillo 17 (Figura 1). Esto se obtiene al medir la cabeza del cepillo y sus cerdas de la siguiente forma:…”

“…Rawls y colaboradores creadores del índice utilizado encontraron relevancia en el tiempo de uso y el desgaste del cepillo y concluyeron que existen diferencias en el desgaste que hace cada individuo. 17 De igual forma, en un estudio realizado por Nava y colaboradores en México encontraron que el desgaste era proporcional al tiempo de uso y que este aumentó al llegar a los tres meses de uso. 23 La correlación entre el nivel de higiene bucal y el deterioro del cepillo fue baja puesto que osciló entre -0,04 y 0,35. van Palenstein Helderman y colaboradores estudiaron la remoción de la placa con un cepillo nuevo y uno viejo en niños con edades entre 7 y 8 años, concluyeron que no existía correlación entre el deterioro del cepillo y la higiene bucal.…”

“…Por tanto, estos resultados coinciden en lo sugerido por la evidencia al indicar que es conveniente hacer un recambio del cepillo a partir del tercer mes. 8,10,17,23,28,29 De acuerdo con los resultados obtenidos en este trabajo, es necesario orientar las campañas para mejorar y facilitar a los niños una técnica de cepillado que sea más efectiva y acorde con cada individuo según su nivel de desarrollo ya que más que promover el hábito es importante lograr que se haga de una buena manera y este cumpla su finalidad. Puesto que los altos índices de placa predisponen a las enfermedades bucales como lo son la caries dental y la enfermedad periodontal.…”

RESUMENObjetivo: determinar el efecto del deterioro del cepillo sobre la higiene bucal en los escolares matriculados en segundo grado de la Concentración Yira Castro evaluados durante el segundo semestre del 2009. Materiales y métodos: se desarrolló un estudio descriptivo de seguimiento a una cohorte con 59 escolares en edades entre 6 y 9 años. Se incluyeron variables sociodemográficas, capacidad funcional motora, actitud del niño a la hora de cepillarse y las relacionadas con la higiene bucal como el deterioro del cepillo de dientes y la cantidad de placa acumulada. Para el análisis estadístico univariado se calcularon medidas de resumen según la naturaleza de las variables, para el bivariado se comparó la higiene bucal y el deterioro del cepillo según control realizado mediante test de Anova para medidas repetidas. Se correlacionó la higiene bucal con el deterioro del cepillo mediante el coeficente de correlación de Spearman, se estableció la asociación de higiene bucal con sus variables explicatorias mediante test de chi cuadrado, test exacto de Fisher y prueba t de Student y se efectúo análisis de sobrevida al deterioro de los cepillos Se consideró significativo un valor de p<0,05. Resultados: el promedio de placa dentobacteriana que representó un nivel de higiene bucal malo y regular fue de (2,6 ± 0,3 y 1,7 ±0,4) y de (2,2 ± 0,6 y 1,5 ± 0,5) antes vs después para el primer y cuarto control respectivamente; los niveles de placa antes vs. después registraron diferencias estadísticamente significativas en los cuatro controles. Al analizar la correlación entre el nivel de higiene bucal y el deterioro del cepillo se evidenciaron bajos niveles de correlación entre estos dos aspectos que oscilaron entre -0,04 y 0,35 Conclusiones: no existió relación entre el deterioro del cepillo dental y el nivel de higiene bucal. El problema relacionado con la higiene bucal fue una mala técnica para realizar su cepillado. [Acevedo LP, Caicedo CJ, León CM, Concha SC.

Methods: an observational following study was done with a 59 school children aged 6 to 9 years old cohort. The variables were: sociodemographic aspects, functional motor ability, attitude of the child at the time of brushing, oral hygiene-related with the toothbrush wear and the amount of dental plaque. The statistical analysis plan included to calculate the summary measures. The analysis to compare the oral hygienic and the toothbrush wear in each control a repeated ANOVA test was applied. The oral hygienic and toothbrush wear correlate was studied with Spearman correlate coefficient. The association the oral hygienic with other variables was evaluat...

“…[13][14][15] Although one investigation reported the amount of toothbrush wear correlated with the length of time in use, 16 other studies found toothbrush wear varies among people and depends mainly on how the toothbrush is used. 13,15,17 Those who brush with high force wear out their brushes earlier than those who brush with light force. 18 The effect of toothbrush wear on the efficiency of home-based plaque control has received little attention in the literature.…”

The purpose of this study was to survey the views of Australian dentists on toothbrush wear, toothbrush renewal periods and recommendations to patients and to investigate the relationship between dentists' views on patients' toothbrush renewal intervals and dentists' own renewal habits. Questionnaires were mailed to 5,596 Australian general dental practitioners and replies received from 3,406 (61 per cent response rate). The majority of respondents (85.7 per cent) felt patients should renew their toothbrushes more often. However, only 45.3 per cent usually made a recommendation to their patients as to when they should renew their toothbrush and only 41.7 per cent thought patients actually followed such recommendations. Most respondents (56.6 per cent) thought the average adult patient should renew a toothbrush every two‐three months. A renewal period of one month or earlier was recommended by 23.8 per cent of dentists; four‐five months by 8 per cent; and six months or longer by 11.5 per cent. A highly significant correlation was found between the renewal periods recommended for patients and the intervals selected by the dentists for their personal brushes (p<0.001; chi‐square test). Bending and splaying of bristles was the sign identified by the majority of dentists (70 per cent) as indicating the need for a new brush. The findings suggest dentists' recommendations concerning toothbrush renewal intervals may be based on their own toothbrush renewal habits. It is also concluded that dentists think patients comply poorly with their recommendations on toothbrush renewal.

SYNOPSISSplaying and curling of bristles is a very important performance characteristic of nylon toothbrushes. For this reason, analytical methods are needed that correlate fundamental physical-chemical properties with the eventural development of bristle splaying. Differential scanning calorimetry, thermogravimetric analysis, and wide-angle X-ray diffraction were each found to identify subtle differences in nylon 612 filament that had been subjected to varying processing conditions during manufacture. These differences were found to be related to water absorption and crystalline perfection and could be correlated with the characteristics of toothbrush wear. From the results, it was concluded that these three methods can be used for quality control and research purposes to predict and to study enduse performance factors such as bristle splaying. 0 1992 John Wiley & Sons, Inc. INTRODUCTlONMost toothbrushes are made from nylon 612 filament. With use, the nylon bristles take on a permanent curl along the outer one-third of their length. This "splaying" process eventually leads to reduced cleaning effciency and to the perception that the brush is "worn out." Filament recovery from bending and machine "scrub" tests are currently used to predict this performance. Such tests are time-consuming, are highly subject to experimental variability, and give only minimal insight into fundamental properties. Thus, analytical methods are needed that rapidly provide information about fundamental physical-chemical properties that are predictive of end-use performance.Wearing out through the development of bristle splaying is one of the most important performance properties of brushes. As part of an effort to ensure consistent filament quality, nylon 612 filament was investigated using thermal analysis and X-ray diffraction techniques. The filament samples were
