The aim of the present study was to evaluate the antimicrobial efficacy of sugar-free chewing gums and also to assess the effect of dosage and frequency of intake of sugar-free gums on Streptococcus mutans count. Method : The sample consisted of 30 subjects, divided into two groups AI and AII. Each group consisted of 15 subjects. Group AI chewed two sugar-free chewing gum, twice daily for 20 mi...

The objective of the study was to find the antimicrobial effect of local brands of toothpastes containing different active ingredients, against aerobic and anaerobic oral flora and Streptococcus mutans; the causative agent of dental caries and dental plaque. The efficacy of eight locally formulated dentifrices was checked against aerobic and anaerobic oral bacteria of 30 subjects. Sterilized sw...

The aim of this study was to determine whether random amplified polymorphic DNA (AP-PCR) analysis is able to differentiate genetically different clones of mutans streptococci, in 22 Brazilian family members. Stimulated saliva samples were collected from fathers, mothers and infants. For 5-18 months babies with erupting primary dentition, plaque samples were collected using sterile tooth pick ti...

The objective of this study was to investigate the ability of biofilm formation among mutans and non mutans oral streptococci and to determine the effect of Lactobacillus acidophilus DSM 20079 as a probiotic strain on the adhesion of selected streptococcal strains on the surfaces. The sample comprised 40 isolates of oral streptococci from dental plaque and caries of volunteer persons. Streptoco...

BACKGROUND The majority of caries lesions in adults occur on the proximal tooth surfaces of the posterior teeth. A comprehensive study of the composition of the oral microbiota is fundamental for a better understanding of the etiology of interdental caries. METHODS Twenty-five caries-free subjects (20-35 years old) were enrolled in the study. The interdental biofilm of four interdental sites ...

Streptococcus mutans have been proposed as the main causative agent of dental cavities. Dental caries is among the most common diseases in the world, this study was done to determine whether PCR analysis is useful to identify and even classify oral and other streptococci. 20 dental plaque samples were collected from teeth, 10 normal sample and 10 from persons with oral problems. The samples wer...

  Objective: Bioactive glass 45S5 is a surface reactive glass-ceramic biomaterial, developed in 1969. BAG 45S5 with particle size of 20-60 nm has the ability of bone regeneration, broad spectrum antibacterial effect, repairs and replaces diseased or damaged bone. The aim of this study was to evaluate the antibacterial activity and determine MIC and MBC values of nano-BAG45S5 on Streptococcus mu...

Background and purpose: Antibacterial properties of restorative materials are of great advantage as they control the progression of tooth decay. The use of self-adhesive composite materials has some benefits such as easier application and reduced treatment time. Because the antibacterial properties of restorative materials can play an important role in preventing secondary decay, especially in ...

AIM To assess the antibacterial and antifungal potentials of different parts of Moringa oleifera plant using different extraction methods in attempts to formulate natural dental remedies from this plant. MATERIAL AND METHODS Three solvents extracts (Ethanol, acetone, and ethyl acetate) of different parts of Egyptian Moringa tree were prepared and tested against oral pathogens: Staphylococcus ...
