Goldman School of Graduate Dentistry, 1984 (Dental Public Health). / Includes bibliographical references (leaves 58-59). / Future dental professionals receive very little information on new dental products.　The goal　of　this project was　to introduce Zendium, a new dentifrice manufactured by CooperCare, Oral-B, to graduating dental　studentS, post doctoral periodontic students and senior dental hygiene students.　This information was presented at　the dental and dental hygiene schools to fifteen (15) dental students, thirteen (13) periodontic students and eighty-one (81) dental hygiene students. Students were asked to complete two questionnaires to evaluate　the appropriateness of the presentation and their reaction to Zendium. Results indicated　that　the students felt　the presentation was appropriate in terms of the educational　level, length of presentation, use of visual　aids and speaker’s knowledge of　the product. Their response to Zendium was mixed, with the highest acceptance of the product by senior dental hygiene students. The students had several　concerns about　the product, including flavor, lack of ADA approval　and　the need for more　long-term clinical　studies　to be conducted in　the United States.　It is hoped　that　this information will aid CooperCare, Oral-B with their marketing strategies of Zendium to other dental professionals.

No entanto, as evidências quanto às recomendações do uso deste produto em crianças ainda são inconsistentes, considerando o balanço entre cárie e fluorose dentária. Sendo assim, o presente estudo teve o objetivo de avaliar as concentrações de flúor na saliva de crianças após escovação com dentifrícios contendo diferentes concentrações de flúor, aplicados em diferentes quantidades, bem como avaliar a ingestão de flúor a partir escovação. Para isso, crianças (n=18, 2-3 anos de idade) foram aleatoriamente distribuídas em seis grupos experimentais, de acordo com possíveis combinações de dentifrícios (0/550/1100 ppm F, como NaF) e quantidade aplicada na escova (0,04/0,16/0,32 g, correspondendo a um grão de arroz, grão de ervilha e técnica transversal, respectivamente). Os voluntários fizeram uso de um dentifrício placebo durante uma semana. No sétimo dia, amostras salivares foram coletadas antes (baseline) e 5, 15, 30 e 60 minutos após a escovação com uma das possíveis combinações de tratamentos. Todo dentifrício expectorado após a escovação foi coletado. As concentrações de flúor foram determinadas após tamponamento com TISAB III (saliva) e por microdifusão facilitada por hexametildisiloxano (conteúdo expectorado). Os dados foram submetidos a ANOV...

Nevertheless, the evidence for recommending such products to children are still inconsistent, given the balance between dental caries and fluorosis. Thus, the aim of the present study was to evaluate F concentrations in saliva of toddlers after brushing with dentifrices containing different F concentrations, applied in different quantities, as well as to estimate F intake from toothbrushing. Toddlers (n=18, 2-3 years old) were randomly assigned into six experimental groups, according to the possible combinations of dentifrices (0/550/1100 ppm F, as NaF) and amount applied on the toothbrush (0.04/0.16/0.32 g, corresponding to rice grain, pea-size and using the transverse technique, respectively). Volunteers used a placebo dentifrice during one week. On the 7th day, saliva samples were collected before (baseline), and at 5, 15, 30 and 60 minutes after toothbrushing with one of the possible treatment combinations. All toothpaste expectorated after brushing was collected. F concentrations were determined after buffering with TISAB III (saliva) and hexamethyldisiloxane-facilitated diffusion (expectorate). Data were submitted to ANOVA or Kruskal-Wallis test, followed by Fisher's LSD or Student-Newman-Keuls' tests, respectively (p<0.05). Brushing with the 550 ppm F toothpaste (pea-size or transversal technique... (Complete abstract click electronic access below) / Mestre
