This research analyzed the dispersion and impact of magnesium oxide nanoparticles (MgONPs) varnish on inhibiting enamel demineralization. A novel MgONPs was prepared in absolute ethanol with rosin 10%, 5%, 2.5%, 1.25% concentrations. The samples were classified into six groups, including four tested varnish, one commercial 5% NaF control groups non-protected sound dental groups. Each group incl...

objective: the purpose of the present study was to assess the microleakage of composite restorations with and without a cervical amalgam base and to compare the results of dif-ferent composites and bonding agents. materials and methods: one hundred and twenty mesio-occlusal (mo) and disto-occlusal (do) class ii cavities were prepared on sixty extracted permanent premolar teeth. the teeth were r...

FLUORIDE RELEASE AND UPTAKE INTO HYDROXYAPATITE FROM EXPERIMENTAL DENTAL VARNISH. I Ahmed (D.D.S., SODM), S Coleman, and CM Carey, School of Dental Medicine, University of Colorado, Denver, CO. Fluoride releasing dental varnishes (F-varnish) typically contain 5% sodium fluoride (NaF) within a resin or rosin base. The concentration NaF that yields optimal fluoride enamel uptake, release, and ant...

Introduction: Topical application of fluoride varnish on the tooth surface prevents dissolution rates materials and increases re-precipitation lost minerals. Objective: To assess effectiveness in primary dentition among preschool children at high risk dental caries. Methods: A randomized controlled trial was conducted with two parallel-group, comprising 3–5-year-old children, 100 each group (Fl...

Maintenance and reliability are crucial aspects for operating construction equipment in harsh environmental conditions. One of the methods used to improve maintenance is oil diagnosis. In this study, monitoring conditions was performed through use an integrated sensor hydraulic equipment. Hydraulic polluted by various materials such as moisture dust. Therefore, present work investigated change ...

AIM To evaluate the effects of novel casein phosphopeptide (CPP) formulations CPP-amorphous calcium phosphate (CCP- ACP) and CPP-amorphous calcium fluoride phosphate (CPP-ACFP) versus fluoride varnish on the remineralisation of enamel white spot lesions (WSLs) over a 12-week follow-up period. MATERIALS AND METHODS STUDY DESIGN Double-blind prospective study. Eligibility criteria were patie...

OBJECTIVE To evaluate the effect of chlorhexidine-thymol varnish alone, its combination with chlorhexidine-fluoride containing dentifrice and fluoride varnish on oral hygiene and caries prevention in orthodontic patients. STUDY DESIGN Sixty patients, aged 12-18, with orthodontic fixed appliances were randomly assigned into three groups as follows: Group 1 (n=20): 1% chlorhexidine and 1% thymo...

BACKGROUND Sjögren's syndrome (SS) patients are prone to caries development due to reduction of salivary flow. Topical fluoride is commonly prescribed for caries prevention. METHODS In this 24-month randomized, double-blind, placebo-controlled clinical trial, SS patients were randomly assigned to receive either fluoride varnish or placebo gel quarterly. Development and arrest of caries at the...

Xylitol is effective as a non-cariogenic sugar substitute. Habitual xylitol consumption appears to select for mutans streptococci (MS) with impaired adhesion properties, i.e., they shed easily to saliva from plaque. One hundred sixty-nine mother-child pairs participated in a two-year study exploring whether the mothers' xylitol consumption could be used to prevent mother-child transmission of m...
