Dental plaque is a dynamic microbial biofilm ecosystem that comprises hundreds of species including difficult-to-cultivate bacteria. We observed the assembly of a plaque bacterial community through 16S rRNA gene analysis. Plaque samples that accumulated on a hydroxyapatite disk for 1, 2, 3, 4, 5, and 7 days with saliva on day 0 were collected from 19 young adults using a removable resin splint....

Oral health promotion to young children is delivered by primary care nurses as part of general health promotion given to all children in Norway. OBJECTIVE The objective was to evaluate established routines for referral of children by primary care nurses to the dental services and to study whether referred children younger than 3 years required contact with dental personnel. METHODS All chil...

Dental plaque is an example of a biofilm; its presence is natural and it supports the host in its defense against invading microbes. In health, the microbial composition of dental plaque is diverse and remains relatively stable over time (microbial homeostasis). The predominant microorganisms prefer host molecules (eg, salivary mucins) and a neutral pH for growth. Under certain circumstances, t...

BACKGROUND Triclosan is a broad-spectrum antimicrobial agent used in toothpaste to reduce dental plaque, gingivitis and oral malodor. This community-level assessment evaluated the susceptibility of dental plaque bacteria to triclosan in samples collected over 19 years. METHODS A total of 155 dental plaque samples were collected at eleven different times over 19 years from 58 adults using 0.3%...

PURPOSE To demonstrate the noninferiority of a new toothbrush head with retractile bristles compared to traditional toothbrush heads on dental models. METHODS The new toothbrush head, mounted on manual and electrical handles, presents retractile bristle groups that can singularly retract over its entire length and offer calibrated resistance. Fourteen gypsum models of dental arches, twelve wi...

The inhibition of acid production from dental plaque and mutans streptococci by epigallocatechin gallate (EGCg), one of the green tea catechins, was examined. The effect of EGCg solution on dental plaque pH was investigated. Subjects rinsed their mouths with 2 mg/ml EGCg solution and then, after 30-min interval, rinsed their mouths with 10% sucrose. Plaque samples were collected at appropriate ...

OBJECTIVES Determination of the relative amounts of mutans streptococcus in both saliva and plaque and to study its correlation with dental caries in children. STUDY DESIGN The study comprised of 60 children aged 3-8 years divided into 2 groups (30 children in each): Group A- Children with more than 4 carious teeth and Group B- Children without caries. Saliva and plaque was collected from chi...

Background: Oral health education is most widely used in prevention of dental diseases. However, there is uncertainty about the value of these interventions. The primary objective of this review was to evaluate the effectiveness of oral health education among school children. Methods: The following databases were selected for identification of studies. The Cochrane central register of controlle...
