Aims: To determine whether personalised Oral Hygiene Advice (OHA) using an intra-oral-camera (IOC) combined with standard OHA as provided in general dental practice reduces plaque levels after 4 weeks more than the provision of standard OHA.
Materials And Methods: 22 healthy adult participants diagnosed with gingivitis took part in this pilot parallel-designed, randomised, examiner-blind, 2x-treatment, study regarding their home-care oral hygiene habits and attitudes to oral health. An IOC-image was taken and plaque, gingival and bleeding scores were recorded.
Purpose: To compare the enamel protection efficacy of a stabilized stannous fluoride dentifrice to a triclosan-containing sodium fluoride dentifrice using a 10-day in situ erosion model, in accordance with the American Dental Association Seal of Acceptance guidelines for enamel erosion control.
Methods: In this single-center, double-blind, randomized, supervised-usage, two-treatment, four-period, crossover study, healthy adult subjects were randomized to a treatment sequence involving the following products: a 0.454% stannous fluoride (1,100 ppm F) dentifrice (Procter & Gamble) and a control dentifrice containing 0.
Objectives: To assess the protective effects of a 0.454% stabilized stannous fluoride dentifrice and a marketed triclosan dentifrice against enamel erosion in a 10-day in situ model.
Methods: This was a double-blind, randomized, 2-treatment, 4-period, crossover in situ trial involving healthy adult participants.
Objectives: To evaluate the ability of a modified in situ model to differentiate dentinal tubule occlusion properties of toothpaste formulations over 10 days of treatment.
Methods: This was a single-centre, three-treatment period, crossover, randomised, single-blind study with healthy participants wearing two lower oral appliances, each retaining four dentine samples, for 10 treatment days during each period of the study. Samples were power-brushed ex vivo twice on each treatment day with a Test toothpaste containing 0.
Objectives: To determine the prevalence of gingival recession (GR) and associations with dentine hypersensitivity (DH), erosive toothwear (BEWE), gingival bleeding (BOP) and periodontal pocketing (PPD) in young European adults.
Materials And Methods: This is a secondary analysis using data collected from 350 UK participants enrolled in a European cross sectional study of 3187 young adults. GR, BOP, PPD, DH (participant and clinician assessment) and BEWE were recorded.
