The prevalence of developmental defects of enamel was assessed in 4805 16-year-old schoolchildren in fluoridated and non-fluoridated areas in Malaysia. In this sample, the mouth prevalence was 56.0%; tooth prevalence was 21.8%. There were significant differences between children in fluoridated and non-fluoridated areas, urban and rural areas as well as between the ethnic groups. However, there ...
PURPOSE The purpose of this study was to evaluate the clinical effect of topical fluoride on retention of light-cured (CLC) and self-cured (CSC) pit and fissure sealants. METHODS CLC and CSC sealants were placed in vivo on opposite sides of the arch before and after fluoride treatment. A total of 122 sealants were placed on virgin permanent molars and premolars of 16 dental hygiene students e...
Fluoridated hydroxyapatite (FHA) coatings exhibit great potential for applications on implants which require good bioactivity and high antibacterial activity. This work is a comparative study of chemical stability, adhesive strength and zeta potential of a nanothick (about 200 nm) FHA coating which is densely and uniformly deposited on a titanium substrate electrochemically. The chemical stabil...
OBJECTIVE To investigate the effect of fluoridated elastomers on the quantity of disclosed dental plaque surrounding an orthodontic bracket in vivo. DESIGN A randomized, prospective, longitudinal clinical trial, employing a split mouth, crossover design. SETTING The Orthodontic Departments of Liverpool and Sheffield Dental Hospitals. SUBJECTS AND METHODS The subjects were 30 individuals a...
OBJECTIVE The objective of this study was to evaluate associations between patterns of infant formula feeding and dental fluorosis and caries in a representative sample of Australian children. METHODS A population-based study gathered information on fluoride exposure in early childhood. Information on infant formula feeding and fluoridation status was used to group children: three groups in n...
OBJECTIVES Claims have been made that the effectiveness of water fluoridation has reduced due to the widespread availability of other sources of fluoride. This study examines the differences in the oral health of children living in fluoridated and non-fluoridated areas of Canterbury and Wellington, New Zealand. DESIGN The data used in this cross-sectional study had been routinely collected in...
Aim:To compare the bacterial level in tooth surface by pre brushing and post brushing using herbal and fluoridated toothpaste Objectives: This study is done to compare the bacterial level using herbal and fluoridated toothpaste. Tooth surface swab is collected. Background: Toothpaste has been manufactured throughout for the reduction in the bacterial level. The present study will be done to com...
Site-specific cancer mortality data for 20 United States cities have been abstracted from United States Government publications to explore further the hypothesis that fluoridation of water supplies causes cancer. Changes in mortality (standardised for age, sex, and ethnic group) between 1958-62 and 1968-72 in 10 fluoridated and 10 non-fluoridated United States cities have been examined. Of the ...
: To evaluate the antimicrobial efficacy of three commercially available toothpastes which are non-fluoridated, fluoridated and one containing prebiotic ingredient on s . Antimicrobial activities prebiotic, fluoridated, non-fluoridated were assessed at different concentrations (100ug, 200ug, 300ug 400ug). Since toothpaste had other proven agents, 100% inulin extract from chicory (prebiotic) was...
