Patient and parental perception of a new fluoride varnish.
The purpose of this study was to compare children's and their parents' acceptability of a new fluoride varnish that purports to have improved taste and color with a control varnish. Sixty patients, 4 to 17 years of age, attending recall appointments at the University of Washington Pediatric Dental Clinic, Seattle, Washington, were randomly assigned to receive 1 of 2 fluoride varnishes. After their appointments, patients and their parents were asked about the varnish's taste and color. There were 32 patients 4 to 7 years of age and 28 patients 8 to 17 years of age. All 8- to 17-year-olds agreed that "white varnish" was preferable to "brown varnish." Most of the 4- to 7-year-olds also agreed that white was better. The 4- to 7-year-olds did not like the taste of either varnish, but the 8- to 17-year-olds preferred the taste of white. All parents cared mostly about efficacy, but agreed that the white, better-tasting varnish was a positive improvement. Parents and their children agreed that though the white varnish is best, the taste was far from ideal for the younger children, based on its single bubble-gum flavor and the standard control fluoride varnish available.

A snapshot of the U.S. postdoctoral pediatric dentistry faculty workforce, 2002.
This study characterizes the faculty shortage in U.S. postdoctoral pediatric dentistry (PD) education. The objectives of the study were to determine: 1) the changes in PD faculty numbers and teaching loads between 1995 and 2002 for postdoctoral PD education, 2) current faculty age and training, and 3) distribution of faculty by age. A questionnaire was sent in 2002 to fifty-four programs, of which forty-six responded (85 percent). Dental school and residency mean class sizes increased in the seven-year study period from 82.8 to 91.8 and from 6.0 to 8.5, respectively. Full- and part-time mean faculty positions increased as did vacancies, the latter growing from 15 to 38.9 and changing during the period from 5 to 10.8 percent of available positions. About one-third of programs used general dentists to teach PD, while programs using foreign-trained educators grew from 4 to 13 percent. Twenty-nine percent of full-time and 27 percent of part-time faculty are fifty-five years or older, and young entry-level faculty, age twenty-five to twenty-nine, represent only 2 percent and 5 percent of full- and part-time faculty respectively. Faculty vacancies have increased along with numbers of students and residents, and the largest segment of PD faculty is within a decade of retirement age.

Clinical evaluation of the plaque removal efficacy and safety of the Sonicare Elite toothbrush.
PURPOSE: To compare the clinical efficacy and safety of a new oral hygiene device, the Sonicare Elite toothbrush, with the established efficacy and safety of the original Sonicare toothbrush (Sonicare Advance). MATERIALS AND METHODS: These two products were evaluated in a 2-week, crossover, single blind clinical trial with 45 subjects. At the baseline visit, a soft-tissue intraoral exam was performed and subjects were randomly assigned to the first treatment. Subjects were given each product for a period of 7 days to become familiar with its use. After the familiarization period, subjects reported for two clinical evaluations. Both plaque removal efficacy and safety were recorded at each evaluation. Plaque was scored using the Turesky Modification of the Quigley-Hein plaque index and safety recorded by an intraoral examination of the soft tissue. After the first treatment arm, subjects crossed over to the other treatment arm and repeated the product use and evaluation sequence. Paired analysis (two-way analysis of variance) was used to detect differences between the two groups. RESULTS: The results indicated that both devices were effective in removing supragingival plaque. The Sonicare Elite was statistically superior, on a percentage reduction basis, in removing supragingival plaque from the dentition taken as a whole (ANOVA; P < 0.05) and was particularly better in hard-to-reach areas such as posterior teeth and interproximal sites (ANOVA; P < 0.05). Neither treatment group exhibited soft tissue concerns, confirming the safety of both these oral hygiene products.

Comparison of the Sonicare Elite and a manual toothbrush in the evaluation of plaque reduction.
PURPOSE: To compare the clinical efficacy and safety of a new oral hygiene device, the Sonicare Elite toothbrush, with a soft-bristled manual toothbrush (Oral-B 35). MATERIALS AND METHODS: This study was designed as a single-blind crossover with two arms. A sample of 25 subjects who met the entrance criteria was divided into two sequences at random: manual-Sonicare Elite, or Sonicare Elite-manual. Within each treatment arm, subjects were given a dental cleaning and polish, and written brushing instructions, and were allowed to use the assigned brush for at least 10 days at home before reporting for two plaque reduction evaluations. Upon completion of the first treatment arm, subjects were assigned the remaining brush and repeated the same protocol as before. Pre- and post-brushing scores were recorded at all visits after 12-18 hours of overnight plaque accumulation and were used to calculate a plaque reduction score at each evaluation. The scores were then averaged over the repeated visits with the same brush and the averages from the two brushes were paired within subjects. ANOVA was performed to determine if a difference existed between the two groups in terms of overall plaque reduction. RESULTS: The Sonicare Elite achieved a significantly greater reduction in plaque than the manual toothbrush (36.0% compared to 25.7%; P < 0.05). No adverse events related to either brush were reported during the study.

Dental plaque as a biofilm and new research on biofilm removal by power toothbrushes.
Dental researchers have only recently begun to regard dental plaque as a biofilm. Dental plaque biofilm is a complex, heterogeneous structure of bacteria cells, a sticky extracellular matrix, and fluid channels. The biofilm must be modeled accurately for laboratory studies to be meaningful. To that end, researchers have compared the sonicare toothbrush to the Braun Oral-B 3D Excel Plaque Remover for the removal of interproximal dental plaque biofilm in an in vitro model. This article defines the concept of biofilms in the oral cavity and reviews how biofilm modeling is showing differences in toothbrush performance.
