Objective Bacterial adhesion is governed by specific and nonspecific interactions such as hydrophobicity. Hydrophobic interactions play a role in the adherence of microorganisms to a wide variety of surfaces and facilitate biofilm formation due to bacterial adhesion. In this article the relation between cell surface hydrophobicity and antibiotic resistance was studied. Materials and Methods ...

Despite recent successes in the control of dental caries, the mechanism of caries development remains unclear. To investigate the causes of dental decay, especially in early childhood caries, the supragingival microflora composition of 20 twins with discordant caries phenotypes were analyzed using high-throughput pyrosequencing. In addition, the parents completed a lifestyle questionnaire. A to...

PURPOSE Few studies have been conducted to investigate the effects, if any, of specific medication used to manage the symptoms of attention deficit/hyperactivity disorder (ADHD) as a risk factor for dental caries. A reported side-effect of the medication is a reduction in saliva. Healthy saliva has been shown to play many important functions in the prevention of dental caries. The focus of this...

Dental caries is one of the most prevalent diseases afflicting mankind. It reached a peak in the 1950s but has been declining drastically in recent years in children and young adults. This article describes the three contributing factors in dental caries: microbial plaque, tooth susceptibility, and diet, and discusses practical preventive measures which help to reduce caries incidence. Some of ...

OBJECTIVE To analyze the effectiveness of motivational interviewing (MI) at improving oral health behaviors (oral hygiene habits, sugar consumption, dental services utilization or use of fluoride) and dental clinical outcomes (dental plaque, dental caries and periodontal status). METHODS A systematic search of PubMed, LILACS, SciELO, PsyINFO, Cochrane and Google Scholar bibliographic database...

The theme for the second National Dental Health Week was a logical sequel to the first namely, “ Plaque the Tooth Enemy”. This theme was aimed at intro­ ducing the public to the major causative factor in dental caries and periodontal disease. Although the public of all ages was to be exposed to the health education facts concerning “ Plaque the Tooth Enemy”, the main target group was the child ...

Few studies have evaluated the oral effects of smokeless tobacco use in adolescents. This study described the oral health status of adolescents who were daily users of local smokeless tobacco (shamma) in Saudi Arabia. A convenience sample of 270 middle-school male students completed a questionnaire and received an oral examination and a saliva cotinine test. Among the students, 96% had plaque d...

PURPOSE The purpose of this pilot project was to determine the effect of a 10% povidone-iodine solution on plaque Streptococcus mutans and on incidence of new caries in young children following dental rehabilitation under general anesthesia. METHODS Twenty-five children ages 2 to 7 years, scheduled for dental treatment under general anesthesia, were enrolled. Children in the experimental grou...

The effects of transport media, temperature, and anaerobiosis on the survival of bacteria from human supragingival dental plaque were studied. Individual samples were obtained by passing sterile, unwaxed dental floss through the interproximal spaces. The plaque-bearing portion of floss was immediately placed in vials containing reduced transport fluid, viability-preserving microbistatic medium,...

BACKGROUND Dental caries has been strongly associated with mutans streptococci, particularly Streptococcus mutans and S. sobrinus. Many studies have linked these organisms to the carious process and counts of mutans streptococci have been used to monitor caries risk. The high levels of caries generally found in Iceland have enabled several studies to be performed on the variation within strains...
