AIM An investigation was conducted in a population of paediatric patients with a high risk of caries in order to assess the association between caries history (CH) and the number of early carious lesions (ECLs) and the frequency and timing of cariogenic food and beverage intake, sugar-containing medication, the frequency and efficacy of tooth brushing, and the use of topical fluorides. MATERI...

INTRODUCTION Knowledge of adhesion patterns of cariogenic streptococci to orthodontic materials can provide valuable information on the cause of enamel demineralization during orthodontic treatment. The purpose of this study was to investigate the adhesion of 2 cariogenic streptococci strains to 7 orthodontic raw materials (3 light-cured orthodontic adhesives, 3 bracket raw materials, and hydro...

The aim of this study is to assess the in vitro shear bond strength and adhesive remnant index (ARI) of one and two-step fluoridated orthodontic resins under conditions that simulate high cariogenic challenge. Edgewise brackets for maxillary central incisors were randomly bonded to 80 bovine incisors, using either Transbond Plus Color Change orthodontic resin and a self-etching primer adhesive ...

OBJECTIVES The evaluation of Mutans streptococci (MS) is one of the index for caries risk. Dentocult(TM) and CRT(TM) are commercial kits to detect and evaluate MS, conveniently. However, the evaluation of MS has also been carried out simply using an instruction manual. But the instruction manual is not easy to use for evaluation of MS. The aim of this study was to examine the utility of modifie...

AIM This study evaluated and improved a protocol for obtaining standard caries-affected dentin (CAD) by Streptococcus mutans biofilm demineralization process. MATERIALS AND METHODS Forty-eight human molars were divided in six experimental groups, according to: period of cariogenic challenge (7, 14 or 21 days) and type of dentin (erupted or unerupted teeth). After complete cariogenic challenge...

Dental caries is a common and costly multifactorial biofilm disease caused by cariogenic bacteria that ferment carbohydrates to lactic acid, demineralizing the inorganic component of teeth. Therefore, low pH (pH 4.5) characteristic signal localised carious environment, compared healthy oral range (6.8 7.4). The development pH-responsive delivery systems release antibacterial agents in response ...

background and objectives: the most prevalent and worldwide oral disease is dental caries that affects a significant pro- portion of the world population. there are some classical approaches for control, prevention and treatment of this pathologic condition; however, the results are still not completely successful. therefore new methods are needed for better management of this important challen...

statement of problem: dental plaque is the main source for dental caries and there is no proper vaccine that can affect dental plaques. objectives: daily use of an efficient anti-plaque product can be very beneficial in plaque control and, thus, prevention of caries. this study aims to evaluate the antibacterial effects of four products of chlorhexidine and fluoride on two types of cariogenic b...
