The study is about evaluating the effects of three remineralising agents i.e. Casein Phosphopeptide - Amorphous Calcium Phosphate [CPP-ACP], Sodium fluoride varnish and Tricalcium phosphate (TCP) on dentin. objective this to see which have a better effect In study, thirty freshly extracted human central incisors are selected with exposed labial surfaces each tooth divided into four quadrants tr...

Smooth rock surfaces in arid environments are often covered with a thin coating of Fe–Mn oxyhydroxides known as desert varnish. It is debated whether such varnish is formed (a) by slow diagenesis of dust particles deposited on rock surfaces, (b) by leaching from the underlying rock substrate, or (c) by direct deposition of dissolved constituents in the atmosphere. Varnishes collected from smoot...

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...

i ntroduction: assessment of cellular cytotoxicity is a regular method for evaluating the biocompatibility of novel materials. in a recent study, 5% fluoride varnish (duraflur) has shown reasonable sealing ability and coverage of root canal walls when used as a sealer. the aim of the present study was to compare cytotoxicity of duraflur varnish with two popular commonly used root canal sealers ...

CONTEXT Antimicrobial efficacy of subgingival chlorhexidine (CHX) application using two different vehicles of delivery. AIMS The aim was to evaluate the efficacy of CHX varnish and gel as an adjunct to scaling and root planing (SRP) in reducing microbial count within moderate to deep periodontal pockets. SETTINGS AND DESIGN Experimental parallel mouth study. SUBJECTS AND METHODS A total o...

Soil-geomorphic studies indicate that six major allostratigraphic units occur in Crater Flat, Nevada, adjacent to Yucca Mountain. These units are, from youngest to oldest, Crater Flat, Little Cones, Late Black Cone, Early Black Cone, Yucca, and Solitario. Presence and degree of differentiation of Av, Ak, Bw, Bt, Btk, Btkq, and Bqkm genetic soil horizons characterize units, confirm relative ages...

OBJECTIVES The objective was to analyze the impact of preventive programmes on oral quality of life in school students aged 11-12 yrs. STUDY DESIGN In the school year 1996/97, a quasi-experimental study was initiated in Granada province with four groups of students aged 6-7 yrs: Sealant + Fluoride (sealants on first permanent molars applied in the health centre for a 3-yr active programme, an...

BACKGROUND This systematic review and meta-analysis evaluated the effectiveness of professional topical fluoride application (gels or varnishes) on the reversal treatment of incipient enamel carious lesions in primary or permanent dentition. METHODS Literature searching was carried out by the authors in PubMed (MEDLINE), Cochrane Central Register of Controlled Trials, Turning Research Into Pr...

The cross-sectional texture of rock varnish varies considerably with the scale of analysis and technique used to image a sample. Each jump in resolution results in new insight, with the current state-of-the-art resting at the nanoscale. One key to nanoscale analysis involves focused ion beam (FIB) techniques used most frequently in material science and semiconductor failure analysis. FIB prepar...
