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 reevaluation 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 reduced caries incidence on approximal surfaces. Frequent repetition of training in meticulous oral hygiene is almost redundant.

Background: Patients on oncologic palliative care (OPC), due to diverse symptomatology and variable severity, tend to present polypharmacy that, although it seems justifiable in many cases, can pose health risks and negative consequences on patients’ quality of life. Thus, it is necessary to evaluate the presence of possible therapeutic futilities, guiding the process of deprescription, in which there is a reduction in the amount of medication after reviewing the treatment objectives and assessing risks and benefits. Aim: The objective of this study was to identify the main classes of drugs that are candidates for the deprescribing for OPC patients by reviewing the literatura of the last 8 years. Methods: The bibliographic search was performed in the Medline and LILACS databases. Inclusion criteria were articles published between 2010 and 2018, which dealt with the topic of deprescription in CPO. The publications were analyzed for Qualis and the level of scientific evidence, in order to identify the main drugs candidates for deprescription. Results: Twenty articles were evaluated, being only 4 randomized clinical trials (RCTs), with level II of scientific evidence. Among the classes of drugs that are candidates for deprescription, the following stand out: statins (20.37%) and antihypertensives (20.07%). ECRs that corroborate with scientific evidence of quality need to be developed for guidelines that make it possible to prescribe, especially for the population in CPO. Conclusion: We highlight the importance of the use of tools to identify inappropriate medicines, and the use of medication conciliation as a means of identifying them, as well as pharmacotherapeutic follow-up.
