One of the most prominent dentists in late-18th century London was Jacob Hemet, member of a long family of dentists. He was appointed royal dentist to Queen Charlotte, wife of George the Third, and to George's favorite daughter, Amelia, and the Prince of Wales. He advertised widely, both in this country and in several European countries, including his native France. However, what makes him note...

Fluoridated hydroxyapatite (FHA) coatings were deposited onto Ti6Al4V substrates by sol-gel dip-coating method. X-ray photoelectron spectroscopy results showed that fluoride ions were successfully incorporated into the hydroxyapatite (HA) lattice structure. The dissolution behavior in Tris-buffered physiological saline indicated that all fluoridated HA coatings had lower solubility than that of...

Objective. The objective of this research was to evaluate the caries control potential of a new fluoride mouthrinse that also contained antimicrobial agents and a biofilm disrupting agent using different in vitro models. Methods. Four in vitro studies were conducted to assess the performance of this three pronged approach to caries control: (1) traditional enamel fluoride uptake, (2) surface mi...

OBJECTIVE There has been a worrisome increase in the prevalence of dental fluorosis worldwide. The objective of this study was to review research on dental fluorosis prevalence in Mexico in order to assess if that prevalence is rising and if dental fluorosis constitutes a public health problem for the country. METHODS Clinical, experimental, and review reports were searched for in a number of...

statement of problem: the effectiveness of fluoride dentifrices in reducing dental caries is well documented. however, not all fluoride dentifrices are equally effective purpose: the objective of this experimental study was to compare fluoride uptake from pooneh pediatric toothpaste and an ada-approved pediatric dentifrice, in sound enamel of primary teeth. materials and methods: in an in vitro...

background: bacteria in dental plaque are one of the main factors causing periodontal disease. the aim was to evaluate and compare the effectiveness of antimicrobial dentifrices with herbal extracts and conventional toothpaste with no antimicrobial action for improvement of oral hygiene  and reduction of gingival inflammation. methods: 48 volunteers with chronic marginal gingivitis were randoml...

PURPOSE The purpose of these examinations was to monitor changes, in the prevalence of dental fluorosis. METHODS In February 1992 and December 1994, children who were residents of one of three communities with varying levels of fluoride in their communal water supply were examined for dental fluorosis. Since some children were available at both examination periods, it was also possible to det...

OBJECTIVES To evaluate the effects of fluoridated bleaching agents and post-bleaching fluoridation treatment on the whitening efficiency and microhardness of bovine enamel. METHODS Twenty five freshly extracted bovine incisors were cut into halves, embedded and then divided into the following five groups: Group 1, untreated controls; Group 2, treatment with 10% carbamide peroxide (CP) bleachi...

OBJECTIVE The primary aim of this study was to compare the in vivo efficacy and safety of dentifrices containing either 5% NovaMin or 5% potassium nitrate, and a non-desensitizing dentifrice, on dentin hypersensitivity in a four-week, double-blind clinical study among a population in south India. In addition, a companion scanning electron microscopy evaluation was performed to demonstrate wheth...
