AIM To derive and evaluate a short form of the Dentine Hypersensitivity Experience Questionnaire. METHODS Data from three previous studies of dentine hypersensitivity (n = 353) were pooled and randomly divided into half. Ten- and 15-item short forms were derived in the first half of the data using the item impact and regression methods. The four short(More)
Remineralization of eroded enamel by dentifrices containing similar sources/concentrations of fluoride was investigated in situ. Fifty-three subjects completed a double-blind crossover study with 3 randomly assigned dentifrice treatments: placebo (0 ppm F, PD); reference (1,450 ppm NaF, RD) and test (1,450 ppm NaF + 5% KNO(3), TD). Fluoride availability for(More)
The current fMRI study investigated cortical processing of electrically induced painful tooth stimulation of both maxillary canines and central incisors in 21 healthy, right-handed volunteers. A constant current, 150% above tooth specific pain perception thresholds was applied and corresponding online ratings of perceived pain intensity were recorded with a(More)
Dentin hypersensitivity is a common condition that affects the adult population worldwide. NovaMin is technically described as amorphous sodium calcium phosphosilicate, and has been shown in laboratory studies to rapidly occlude dentin tubules and form a protective hydroxyapatite-like layer on the dentin surface. A number of clinical studies investigating(More)
AIM To develop and validate a condition specific measure of oral health-related quality of life for dentine hypersensitivity (Dentine Hypersensitivity Experience Questionnaire, DHEQ). MATERIALS AND METHODS Questionnaire construction used a multi-staged impact approach and an explicit theoretical model. Qualitative and quantitative development and(More)
AIM To validate the Dentine Hypersensitivity Experience Questionnaire in terms of responsiveness to change and to determine the minimally important difference. MATERIALS AND METHODS The study was a secondary analysis of data from three randomized controlled trials with 311 participants. Three aspects of responsiveness were examined: change within(More)
A comparison of the desensitising efficacy of two commercially available dentifrices with different modes of action was conducted in a randomised, examiner-blind, two-arm, parallel group, 8-week, longitudinal clinical study. Dentifrice A, (Sensodyne Multi Action Iso-Active), contained 50000 ppm KNO(3) and 1450 ppm fluoride as NaF. Dentifrice B, Colgate(More)
OBJECTIVE This study was undertaken to confirm the efficacy of a novel 5% KNO3 gel-to-foam dentifrice, and to determine the effect of brushing duration on the relief offered from the novel dentifrice to subjects with sensitive molars. METHODS This was a randomized, examiner-blind, two-arm, parallel-group, 12-week, longitudinal study of 141 subjects,(More)
We present the design, construction, and performance of a novel multi-injector gas jet delivery capable of operating in a magnetic resonance imaging environment. This apparatus is computer controlled and built with two separate pneumatic circuits enabling gas jet applications at variable sites through four independently activated injectors. Gas jet delivery(More)
