RUIZ SEDANO, TE et al. The importance of night tooth brushing before sleeping in the prevention of dental caries: Study on childhood population. Av Odontoestomatol [online]. 2007, vol.23, n.1, pp.45-50. ISSN 2340-3152.

In the present study we are questioning if the [three time a day tooth brushing is really essential and if it is the [opposite case, what time of the day would be most important for mechanical elimination of dental plaque. For this purpose we have planed a transversal study on 214 pupils aged 6 to 12 years in the period [of 2004-05 scheduled school coarse. On each of them was applied the "Partial Exam type III" [which is recommended from International Dental Federation and which is considered as standard procedure on prevalence of dental caries study. We obtained following results: 1. Tooth brushing by night before sleeping is a favourable protection factor from dental caries, being correspondent odd-ratio adjusted on 0.339 (interval of confidence is 95% [0.159; 0.722]). 2. Consuming the sugar more than one time a day causes higher risk for dental caries apparition than one time a day consumption of sugar, being correspondent odd-ratio adjusted on 1.998 (interval of confidence is 95% [1.090;3.665]). 3. The children attending public schools have higher risk of dental caries presence than the children attending private schools being correspondent odd-ratio adjusted on 2.019 (interval of confidence is 95% [1.105;3.691]). 4. The objectives on dental caries marked from WHO are carried out on the studied population.
