This study evaluated the effects of a new oral hygiene training program on approximal caries in a population of 12-13-year-old Brazilian schoolchildren with a well-established habit of daily toothbrushing with a F dentifrice. Two hundred twenty-two children were randomly allocated into two test groups (I and II) and one control group (III). Group I subjects were trained to establish needs-related oral hygiene habits based on self-diagnosis and a new behavioral principle, the 'linking method', for establishment of habits. The first three visits (20 minutes each) were scheduled at two-day intervals. They were recalled for a monthly check-up during the first 4 months, and then every 3 months for re-evaluation of the results based on self-diagnosis. Group II subjects were recalled at the same intervals for detailed oral hygiene instruction on how to clean every tooth surface using dental tape, toothbrush, and fluoride dentifrice. Group I developed significantly fewer (p <0.001) new approximal manifest (dentin) caries lesions than groups II and III. The mean values (SEM) were 2.3(0.29), 4.7(0.59), and 5.3(0.68), respectively. The conclusions from our study are: In a toothbrushing population using fluoride dentifrices and fluoridated drinking water, the oral hygiene training program with behavioral modification significantly reducedcaries incidence on approximal surfaces. Frequentrepetition of training in meticulous oral hygiene is almost redundant.
