BACKGROUND Ethnomedicine is gaining admiration since years but still there is abundant medicinal flora which is unrevealed through research. The study was conducted to assess the in vitro antimicrobial potential and also determine the minimum inhibitory concentration (MIC) of Citrus sinensis peel extracts with a view of searching a novel extract as a remedy for dental caries pathogens. MATERI...

سلول های بنیادی جنینی موشی ابزاری ارزشمند برای انجام مطالعات تمایز سلولی در شرایط in vitro هستند. تمایز سلولی فرایندی جدایی ناپذیر از رشد و نمو موجودات پرسلولی است. در این مطالعه نقش مسیر آپوپتوتیک میتوکندریایی و تغییرات سطح انرژی سلول در فرایند تمایز سلول های بنیادی موشی به کاردیومایوسیت و آپوپتوز بررسی شده است.

Background: Dental caries is the most frequent chronic disease worldwide. However, can be prevented or arrested. Recently interest in use of silver diamine fluoride (SDF) has been growing. a solution containing ionic silver, fluoride, and ammonia that arrests progress carious lesions prevents development future caries. In Vitro studies demonstrated SDF increases pH biofilm, reduces dentin demin...

Introduction: The development of a self-limiting caries removal technique would be of great clinical importance. Smart bur II is a relatively new bur in the dental market and its manufacturer is claiming that it is the ultimate bur for selective caries removal. Objectives: The aim of this study was to evaluate caries removal time and efficacy of Smart bur II in comparison with conventional carb...

This study was undertaken to validate the caries status of 214 teeth by serial sectioning and microscopy after caries diagnosis using four methods. Two hundred and fourteen extracted human teeth with varying degrees of caries were mounted in the jaws of nine training manikins. All tooth surfaces were examined and recorded for caries by four dentists using bitewing radiographs, fibre-optic trans...

In this paper we present the findings of a study designed to test the usefulness of an ecological model containing factors believed to affect children's oral health both directly and indirectly. It has long been accepted that there are multiple factors involved in the etiology of dental disease-in this case, caries. However, most dental research uses explanatory models involving a limited range...

BACKGROUND The incorporation of fluoride into sealants has been viewed as a viable way to prevent pit-and-fissure caries by potential inhibition of demineralization through the release of fluoride to enamel. The authors conducted a study to examine the effect of a recently introduced fluoride-releasing sealant (ProSeal, Reliance Orthodontic Products, Itasca, Ill.) on enamel demineralization in ...
