RESUMO
OBJECTIVE: The objective of this study was to compare the efficacy of two dental brushing techniques in relation to the lift lip method to control oral hygiene. METHODOLOGY: This controlled and randomized field trial included 40 preschool children aged 24-59 months, divided into four groups: Group A (modified bass without lift the lip), Group B (modified bass with lift the lip), Group C (horizontal technique with lift the lip), and Group D (horizontal technique without lift the lip). The dental plaque accumulation was recorded through the O'Leary index. In addition, to perform hygiene control, the plaque index was performed in the initial evaluation at 7 and 14 days. RESULTS: ANOVA and Friedman test were applied to compare oral hygiene in each group. Finally, Kruskal-Wallis test was applied to compare groups at 7 and 14 days. The children with the modified Bass associated to the lift the lip had significantly more plaque removed at 7 (P = 0.041) and 14 days (P = 0.027) than other techniques. CONCLUSIONS: The modified Bass related to the lift-the-lip technique was the most effective for plaque removal in preschool children at 7 and 14 days.

El concepto de la caries dental ha evolucionado a través del tiempo, y ha pasado por una diversidad de teorías para poder explicar su etiología. El propósito de esta revisión de literatura es relatar las teorías relacionadas al origen de la caries dental y la manera en que los conceptos se han modificado, producto de las diversas investigaciones. Múltiples teorías se desarrollaron, entre ellas la de Willoughtby Miller, uno de los principales investigadores, quien propuso la teoría químico-parasitaria, la cual refiere que la desmineralización del esmalte era el resultado de los ácidos producidos por microorganismos en la cavidad oral. Esta teoría supera a la de la triada ecológica, que identificó como agente cariogénico a la sacarosa, estableció el carácter infec- tocontagioso de la enfermedad y respon- sabilizó al Streptococcus mutans como principal agente causal. De la misma manera, surgen nuevas teorías que serán explicadas en el presente artículo, las cuales nos permiten establecer los conceptos actuales de la caries dental y su desarrollo. (AU)
The concept of dental caries has evolved over time, passing through a variety of theories in order to explain its etiology. The purpose of this literature review is to address theories related to the origin of dental caries and the ways in which concepts have been modified following research. Multiple theories have been developed, one of the most notable of which has been that of Willoughby Miller, a leading researcher, who proposed the "chemical-parasitic theory" for the demineralization of enamel as a result of the acids produced by microorganisms in the oral cavity. This led to the "ecological triad" theory, which identified sucrose as a cariogenic agent, establishing the infectious-contagious character of the isease and identifying S. mutans as the main causative agent. new theories have also emerged, as this article will explain, allowing us to develop our current concepts associated with dental caries disease and its development.
