Background: Oral infections caused by microorganisms have led to increased risk of oral health problems like dental caries (DC). Streptococcus mutans and Candida albicans are the organisms responsible for DC. The goal presented study was investigate potential probiotics prevent treat An in vitro assay developed several probiotic strains their ability inhibit aforementioned pathogens. Methods: 4...

AIM This research was aimed to investigate the in vivo and in vitro performance of traditional and novel methods in the detection of occlusal caries in primary teeth. MATERIALS AND METHODS One hundred twenty primary molar teeth were assessed by two examiners both in vivo using ICDAS II, radiographic examination, DIAGNOdent pen, CarieScan PRO and SoproLife camera and in vitro using the mention...

A new fluoride releasing resin-ionomer cement was used for bonding of gallium alloy restorations in vitro. Etching, priming, and fluoride releasing resin-ionomer cement were used in the experimental group (ARG), prior to placement of the gallium alloy restorations. Three different controls were used: gallium alloy only (G), no etching, fluoride releasing resin-ionomer cement, gallium alloy (RG)...

background: vitrification has proven to be more effective than slow freezing methods to cryopreserve mammalian oocytes. the objectives of this study were to evaluate the effects of vitrification on immature and in vitro matured, denuded and cumulus compact goat oocytes and their subsequent fertilization. methods: oocytes were either cryopreserved as immature cumulus compact (imcc) (n=98 exp 1; ...

background: it is important to protect oocytes and embryos from oxidative stress in the culture medium. melatonin has been shown to be a direct free radical scavenger. objective: effect of melatonin during in vitro oocyte maturation, fertilization and embryo development of mouse oocytes was evaluated. materials and methods: oocytes from supper-ovulated mouse were divided to two groups: cumulus ...

A lactate dehydrogenase-deficient (Ldh-) mutant of a human isolate of Streptococcus mutans serotype c was tested in a gnotobiotic rat caries model. Compared with the wild-type Ldh-positive (Ldh+) strains, it was significantly (alpha less than or equal to 0.005) less cariogenic in experiments with two different sublines of Sprague-Dawley rats. The Ldh- mutant strain 044 colonized the oral cavity...

PURPOSE This study compares four chemotherapeutic regimens used for inhibiting carious lesion progression: silver nitrate (AgNO3); silver fluoride/stannous fluoride (AgF/SnF2); silver diammine fluoride (SDF); and chlorhexidine (CHX). METHODS For this study, a bacterial model system containing Mutans streptococci (MS) and Lactobacilli casei (L) was used to generate carious lesions on 85 extrac...

Background. A caries lesion causes changes in the optical properties of the affected tissue. Currently a caries lesion can be detected only at a relatively late stage of development. Caries diagnosis also suffers from high interobserver variance. Methods. This is a pilot study to test the suitability of an optical diffuse reflectance spectroscopy for caries diagnosis. Reflectance visible/near-i...

OBJECTIVE THE AIMS OF THIS STUDY WERE TO: (1) evaluate the caries risk in young adults using Cariogram and (2) compare the efficiency of Cariogram with the regression risk models created using the same variables in Cariogram by examining the actual caries progression over a 2-year period. METHODS This study included 100 subjects that were either twenty or twenty-one years-old. Data on general...

UNLABELLED Identifying caries risk factors is an important measure which contributes to best understanding of the cariogenic profile of the patient. The Cariogram software provides this analysis, and protocols simplifying the method were suggested. OBJECTIVES The aim of this study was to determine whether a newly developed Caries Risk Assessment (CRA) form based on the Cariogram software coul...
