Background and Aim: Since fluoride therapy is usually the first step of treatment in pediatric dentistry and it may interfere with other treatments, such as composite fill-ing, this study aimed to evaluate the possible effects of topical pre-fluoride therapy on marginal microleakage of composite restorations in deciduous teeth. Materials and Methods: In this in-vitro study, 30 deciduous canine...

Objective: To assess the effect of acidulated phosphate fluoride gel (APF), sodium fluoride varnish (NaF) and casein phosphopeptide-amorphous calcium phosphate fluoride paste (CPP-ACPF) on the dental erosion produced by coca cola in primary and permanent teeth. Design: Sixty extracted human primary molars (n = 30) and young permanent premolars (n = 30) were used in this study. The coronal porti...

background: some studies have shown that casein phosphopeptide-amorphous calcium phosphate (cpp-acp) and acidulated phosphate fluoride (apf) gel can protect teeth against erosion. the aim of this study was to assess whether cpp-acp and fluoride could reduce enamel wear rates under erosive conditions simulating abrasion and acidic diet regimen. materials and methods: enamel specimens consisted o...

OBJECTIVE To study the prognostic value of the antiperinuclear factor (APF), determined by an indirect immunofluorescence test (IIF) and a recently developed anti-citrullinated cyclic peptide (CCP) ELISA, in combination with rheumatoid factor (RF) status, in early RA (< 1 year). METHODS A total of 249 participants in a randomized trial of treatment strategies were divided into 4 groups accord...

Most studies dealing with the caries preventive action of Nd:YAG laser have been done in permanent teeth and studies on primary teeth are still lacking. The aim of this study was to evaluate in vitro the effect of Nd:YAG laser combined or not with fluoride sources on the acid resistance of primary tooth enamel after artificial caries induction by assessing longitudinal microhardness and deminer...

Background: Fixed appliances hinder the effective control of plaque accumulation and white spot lesions may develop under the ill fitting bands or adjacent to the stainless steel brackets during orthodontic treatment particularly the etching process. Aims and Objectives: Comparative study of tensile bond strength of an orthodontic adhesive with and without fluoride application after acid etchin...

The purpose of the present study was to investigate whether fluoride (F) ions are really capable of the repair (remineralization) of damaged crystals and useful for reinforcing the quality (i.e. modify the crystal structure) of tooth enamel using transmission electron microscopy and Raman microprobe analysis. Additionally, carbonic anhydrase activity was measured in immature enamel tissue to co...

Aggregation-promoting factor (APF) was originally described as a protein involved in the conjugation and autoaggregation of Lactobacillus gasseri 4B2, whose corresponding apf gene was cloned and sequenced. In this report, we identified and sequenced an additional apf gene located in the region upstream of the previously published one. Inactivation of both apf genes was unsuccessful, indicating ...

Objective: To evaluate the effect of different preparations fluoride gels on salivary pH albino rats. Material and Methods: This experimental study consisted 40 Albino rats randomly divided into four equal groups. Group A was control group received no intervention. Experimental B a topical application 0.2% sodium gel. C stannous gel 0.4%. D APF (1.23% acidulated phosphate gel). The were applied...
