The aim of the present study was to evaluate the in vitro caries preventive effect of fluoridated orthodontic resins under pH cycling with two types of acid demineralizing saliva. Brackets were bonded to 60 bovine incisors, using either Transbond Plus Color Change (n=30) or Orthodontic Fill Magic (n=30) orthodontic resins. Each group of resin was divided into 3 subgroups (n=10): immersion in re...

BACKGROUND Several lines of evidence indicate that oral microbial flora play a critical role in the pathogenesis of Behçet disease. Saliva flow rate, buffer capacity and microorganism content are very important in the maintenance of oral health. AIMS We aimed to evaluate saliva flow rate, pH, buffer capacity and Streptococcus mutans and Lactobacilli content along with the decayed, missing, an...

OBJECTIVES The purpose of this study was to compare the anti-mutagenicity of Salivette and test-tube sampling saliva. In addition, the relation between the inhibiting and pH-buffering capacities of saliva was investigated. METHODS Subjects were 52 healthy female university students. The collection of saliva samples was carried out using 2 sampling devices; test-tube and Salivette. The anti-mu...

OBJECTIVE In the recent years, herbal oral hygiene products have gained increasing attention. The aim of this study was to assess the effects of three types of mastic gums on the level of Mutans streptococci, Lactobacilli and pH of the saliva. MATERIALS AND METHODS Forty-two students in the age range of 20-30 years were divided into three parallel groups; each of them separately used pure mas...

OBJECTIVE. The purpose of this study is to evaluate the ability of two commercial strip tests and laboratory titration to detect saliva buffer capacity. MATERIALS AND METHODS. Sixty-four patients were examined. Stimulated saliva was collected and buffer capacity was determined with two different chair-side strip tests in addition to immediate transportation to the laboratory to check the buffer...

OBJECTIVE To assess the pH of regular and light cola-based drinks and energy drinks, and examine the acid neutralizing capacity by the addition of artificial saliva. MATERIALS AND METHODS Ten packages of each product purchased locally at different stores were evaluated. The pH was measured by a pH-electrode calibrated in standard buffer solutions. To assess the pH neutralizing capacity, 1 ml/...

Introduction: Since pharmaceutical syrups are widely taken by children in Iran, drop of pH in oral cavity and dental decay resulted from the syrups are of high importance. This research aims to study buffering properties of saliva when in contact with some of vitamin syrups available in pharmaceutical market of Iran. Methods: In the present study, 1 milliliter (ml) of 6 samples of vitamin sy...
