Pilot study on the clinical and microbiological effect of subgingival glycine powder air polishing using a cannula-like jet

Abstract ObjectivesTo assess the efficacy of subgingival glycine powder air polishing (GPAP) during supportive periodontal therapy (SPT). MethodsEach quadrant of 25 subjects was randomly assigned to the following treatments: subgingival scaling with hand instruments (SRP), GPAP, subgingival ultrasonic debridement (UD) and no subgingival treatment (NT). Clinical recordings included the following: probing pocket depth (PPD), gingival recession (RE), clinical attachment level (CAL), Gingival and Plaque Index. Subgingival plaque samples were taken from two sites >4 mm per quadrant. Therapy, recordings and microbial sampling were performed at baseline, 3 and 6 months, while at 1 month only clinical…Read more

Disparity in perception of the working condition of dental hygienists between dentists and dental hygiene students in Japan

Abstract ObjectivesIn Japan, there continues to be a shortage of active dental hygienists. The scope of dental hygienists' practice is also considered to be unclear. One of the reasons for this is that dental hygienists find the working conditions during dental hygiene education different from those in reality. The purpose of this study was to clarify the actual working condition of dental hygienists in dental clinics, as well as evaluate the awareness of dental hygiene students and dentists regarding the working condition of dental hygienists. MethodsQuestionnaires were sent by post to 481 dentists…Read more

Steep decline in tooth loss, increase in socioeconomic disparities found by study

Edentulism (tooth loss) has been the focus of a recent study, which traced it over the last hundred years. The project's report highlights the numbers of people losing teeth and requiring dentures. The single most influential determinant of the decline was the passing of generations born before the 1940s, whose rate of edentulism incidence far exceeded later cohorts. High income households experienced a greater relative decline, although a smaller absolute decline, than low income households.Read more

Best way to brush teeth? Even dentists, dental associations don’t agree

Advice on how we should brush our teeth from dental associations and toothpaste companies is ‘unacceptably inconsistent’, finds new research. "The public needs to have sound information on the best method to brush their teeth," says the senior author of the study. "If people hear one thing from a dental association, another from a toothbrush company and something else from their dentist, no wonder they are confused about how to brush. In this study we found an unacceptably inconsistent array of advice from different sources.Read more
