AIM This 12-week prospective, randomized, double-blind, two-center trial evaluated the impact of a microcrystalline zinc hydroxyapatite (mHA) dentifrice on plaque formation rate (PFR) in chronic periodontitis patients. We hypothesized that mHA precipitates cause delayed plaque development when compared to a fluoridated control (AmF/SnF2), and therefore would improve periodontal health. MATERI...

Aim: Several dentifrices have been shown to be effective in reducing dentine hypersensitivity ® (DH). The aim of the present study was to evaluate the desensitizing efficacy of Aclaim toothpaste. Materials and Method: A double blind randomized controlled clinical trial was performed on 40 ® subjects in which 20 were asked to use Aclaim toothpaste (test group) and 20 were asked to use fluoridate...

AIM To determine the concentration of fluoride in saliva and supragingival dental plaque at designated time intervals after consumption of snacks prepared with a standardised amount of fluoridated salt. STUDY DESIGN The investigation had a single blind prospective crossover design. METHODS A group of 11 healthy young adults volunteered to participate after verbal and written information and...

This study aimed to investigate root caries prevalence in areas with and without water fluoridation at the Southeast region of São Paulo State, in the adult population, employees of public and private schools, and elderly population. Epidemiological surveys were conducted according to the World Health Organization guidelines (1997), including 1,475 dentate individuals aged 35 to 44 years and 65...

OBJECTIVE To fabricate polymeric nanocomposites with excellent photoluminescence, magnetic properties, and stability in aqueous solutions, in order to improve specificity and sensitivity of cellular imaging under a magnetic field. METHODS Fluoridated Ln(3+)-doped HAP (Ln(3+)-HAP) NPs and iron oxides (IOs) can be encapsulated with biocompatible polymers via a modified solvent exaction/evaporat...

The chemical changes which occur during the process of carious destruction of enamel are complex due to a number of factors. First, substituted hydroxyapatite, the main component of dental enamel, can behave in a very complex manner during dissolution. This is due not only to its ability to accept substituent ions but also to the wide range of calcium phosphate species which can form following ...

OBJECTIVE To examine the effect of water fluoridation, both artificial and natural, on dental decay, after socioeconomic deprivation was controlled for. DESIGN Ecological study based on results from the NHS dental surveys in 5 year olds in 1991-2 and 1993-4 and Jarman underprivileged area scores from the 1991 census. SETTING Electoral wards in three areas: Hartlepool (naturally fluoridated)...
