BACKGROUND The use of fixed and/or removable dental devices is an attributable factor that may affect the oral cavity homeostasis. The aim of this study was to monitor the oral environmental changes caused by dental devices, as sports mouthguards with the aid of a chair-side test. METHODS Sixty children with sports-mouthguards were analyzed at baseline (T0), after 6 months of dental devices u...

Dental biofilms are implicated in the formation of caries and periodontal disease. A major constituent of the supragingival biofilm is Streptococcus mutans, which produces lactic acid from sucrose fermentation, enhancing enamel demineralization and eventual caries development. Caries prevention through F inhibits enamel demineralization and promotes remineralization. Fluoride also exerts effect...

OBJECTIVES The aim of this study was to determine whether measurements of volatile sulfur compounds (VSCs) are useful to predict colonization of periodontopathic bacteria. For this purpose, we assessed the relationships among distributions of 4 species of periodontopathic bacteria in tongue coating and dental plaque, oral conditions including VSC concentration in mouth air, and smoking habit of...

OBJECTIVE To investigate the neutralising effects of subsequent arginine bicarbonate rinse on sucrose-induced decrease in plaque pH with interdental plaque pH telemetry. METHODS Six participants wearing partial lower prostheses incorporating a miniature glass pH electrode were included. After 5 or 6 days of plaque accumulation on the tip of the electrode, the subjects rinsed with a 15 ml 10% ...

Background and Aim: Hearing impairment is a leading challenge in the education of deaf children. Compared to normal children, hearing-impaired (HI) children have poor oral health due to a lack of communication skills and effective health educations. This leads us to search for a proper method to educate these children. The present study aimed to assess the effect of different educational method...

BACKGROUND AND OBJECTIVE Dental calculus occurs as a consequence of supersaturation of saliva with respect to calcium phosphates. This mineralization of dental plaque can be delayed by the presence of crystallization inhibitors, such as pyrophosphate or bisphosphonates. Phytate inhibits brushite and hydroxyapatite crystallization and has the potential to prevent dental calculi formation. The ai...

Several foods have been shown to contain natural components (especially polyphenols) which display anti-adhesive properties against Streptococcus mutans, the aetiological agent responsible for dental crown caries, as well as inhibition of glucosyltransferases, which are the S. mutans enzymes involved in the synthesis of an adherent, water-insoluble glucan from sucrose. Other studies have demons...
