This study was conducted to evaluate the effect of fluoride varnishes containing different calcium phosphate sources on demineralization of initial primary enamel lesions. Forty-eight sound primary incisors were completely coated with nail varnish except for two 1x1 mm windows before being placed in demineralizing solution for 4 days. After demineralization, one of the windows in each tooth was...

INTRODUCTION This study was carried out to evaluate the bacterial leakage of root canal fillings when cavity varnish containing 5% fluoride (Duraflur) was used as root canal sealer. METHODS AND MATERIALS Root canals of 88 straight single-rooted teeth were prepared. Eighty teeth were randomly divided into 3 experimental groups (n=20) and two positive and negative control groups of ten each. Th...

INTRODUCTION Dental caries is a major public health problem, and Streptococcus mutans is considered the main causal agent of dental caries. This study aimed to compare the effect of three re-mineralizing materials: resin infiltrant, fluoride varnish, and nano-hydroxy apatite paste on the surface hardness and adhesion of Streptococcus mutans as noninvasive treatments for initial enamel lesions. ...

Received: 28 Dec 2010 Accepted: 27 August 2011 Abstract Background and Aim: Fluoride has an important role in the prevention of caries. This study assessed the efficacy of three types of topical fluoride: fluoride varnish, APF gel (sultan), APF gel (Kimia) in protecting the enamel from demineralization in an in vitro environment. Materials and Methods: Sixty human caries-free premolars where ra...

OBJECTIVE To develop a scientifically current and evidence-based protocol for the use of fluoride varnish for the prevention of dental caries among high-risk children and adolescents. METHODS Previous systematic reviews on this topic were used as the basis for the current review. Ovid MEDLINE, CINAHL and several other relevant bibliographic databases were searched for English-language article...

BACKGROUND The majority of the detected increment in dental caries is confined to pit and fissure surfaces of first molars. Application of pit and fissure sealants and topical fluorides are widely used procedures in the prevention of decay, and their effectiveness in caries prevention has been proved by systematic reviews. OBJECTIVES The objective of this study was to compare the effectivenes...

Objective: This study aimed to compare the effect of using Casein phosphopeptide – amorphous calcium phosphate (CPP-ACP) paste, Remin-Pro and Fluoride Varnish on remineralization of enamel lesions. Methods: In this experimental-in vitro study, 60 intact premolars and molars were used and flat enamel surfaces were prepared. The specimens were divided into 6 groups (N=10). After primary DIAGNO...

Objectives: This study aimed to assess tooth discoloration at 6 months following the use of 5% fluoride varnish (Duraflur), AH 26, zinc oxide eugenol (ZOE)-based sealer and mineral trioxide aggregate (MTA)-based sealer in extracted premolars. Materials and Methods: In this in vitro, experimental study, 75 freshly-extracted human premolars with completely formed roots underwent root canal treat...
