Aim. The aim of the present study was to search the manner in which cariogenic bacteria might coexist with know bacteria that produce volatile sulfur compounds and represent the cause of habitasis. Materials and methods. 100 patients aged 11-21y with palatal clefts and malocclusions were divided into two groups: group A was treated with fixed orthodontic appliances, group B was treated with rem...

OBJECTIVES 1. To determine the in vitro antibacterial effectiveness of the orthodontic bonding Transbond XT (3M Unitek) and four self-etching adhesives with possible use in orthodontic bonding (Clearfil Protect Bond, CPB; Clearfil Self-etching Bond, CSB; Transbond Plus Self-Etching Primer, TSEP; iBond) against Streptococcus mutans and Lactobacillus gasseri in order to compare that capacity amon...

Background & Aim: Due to the prevalence of oral bacteria, their complications and increased microbial resistance and also recognition of the antibacterial properties of Polylophium involucratum, in this study, the antimicrobial properties of this plant essential oil were tested in different dilutions on oral bacteria at the Faculty of Microbiology of the Islamic Azad U...

AIMS Bronchial asthma constitutes important problem worldwide. This chronic lung disease has detrimental effect in the oral cavity like reduction of salivary secretion, change in salivary composition and pH. MATERIALS AND METHODS This study was conducted to compare the prevalence of dental caries in asthmatic children and healthy children, and also to evaluate the correlation between the Stre...

A novel furanone derivative and a polyacid constructed from it were synthesized, characterized and formulated into experimental high strength cements. The compressive strength (CS) and Streptococcus mutans viability were used to evaluate the mechanical strength and antibacterial activity of the cements. The effect of human saliva and aging were investigated. The antibacterial activity against L...

Materials Methods: The study sample consisted 117 eligible participants aged 12–18 years. They were divided into control, CHX...

OBJECTIVE Dental caries is a common infectious disease. Streptococcus mutans is the pre-valent decay microorganism. The anti Streptococcus mutans activity of non fermented and semi-fermented tea has been shown. The aim of this study was to determine the anti Streptococcus mutans activity of Iranian green and black tea (non fermented and fermented type). MATERIALS AND METHODS The study was exp...

OBJECTIVES Glass ionomer cements (GICs), which are biocompatible and adhesive to the tooth surface, are widely used nowadays for tooth restoration. They inhibit the demineralization and promote the remineralization of the tooth structure adjacent to the restoration, as well as interfere with bacterial growth. Hence, the present study was conducted to assess and compare the antimicrobial activit...

Studies have shown that silver diamine fluoride (SDF) is an effective agent to arrest and prevent dental caries due its mineralizing antibacterial properties. While plenty of studies investigated the properties, there are few papers examined effect on oral biofilm. The objective this study was identify Method: keywords used were (silver OR diammine SDF AgF AND biofilm plaque). Two reviewers scr...
