The aim of this study was to investigate the relationship between tooth-brushing angle and efficacy of plaque removal. The subjects in this study were 72 students (18-21 yrs.) from paramedical schools. They answered the questionnaire of the Hiroshima University-Dental Behavioral Inventory (HU-DBI) to assess dental health behavior, and then received examinations of tooth-brushing angle, efficacy...

Evidence from clinical research indicates that there is a significant relationship between microbial dental plaque and periodontal disease [1-3]. Epidemiologic data suggests the association of chronic gingivitis and bacterial plaque adhering to tooth surface [4-6]. Clinical and invivo studies have demonstrated the occurrence of metabolic events by the microbial dental plaque in the presence of ...

OBJECTIVES Helicobacter pylori (H.pylori) accounts for gastritis, peptic ulcer and is a probable cause of gastric cancer. Since its detection in the oral cavity, concerns have been raised about dental plaque as a reservoir for reinfection. The aim of this study was to detect the organism in the dental plaque and to determine the association, if any, between H. pylori gastritis and dental plaque...

BACKGROUND Dental plaque, deposition of microorganisms embedded in extracellular matrix, initiates dental caries and periodontal diseases Thus, removal of dental plaque by mechanical or chemical means is the key intervention in prevention of dental caries and gingivitis. METHODS To compare the efficacy of chlorhexidine (0.2%) and sodium fluoride (0.05%) mouthwashes in reduction of plaque depo...

Dental caries has a polymicrobial etiology within the complex oral microbial ecosystem. However, the overall diversity and structure of supragingival plaque microbiota in adult dental health and caries are not well understood. Here, 160 supragingival plaque samples from patients with dental health and different severities of dental caries were collected for bacterial genomic DNA extraction, pyr...

Background and aim: the present study aimed to assess the effect of teeth whitening strips on dental plaque pH in vivo. Materials and Methods: This in vivo experimental study was conducted on 21 individuals, who were requested to use Crest 3D whitening strips for 30 minutes once a day and for 14 days according to the manufacturer’s instructions. Dental plaque pH was measured using GC p...

Streptococcus mutans (MS) and its biotype I are the strains most frequently found in dental plaque of young children. Our results indicate that in children pyruvate kinase (PK) activity increases significantly in dental plaque, and this corresponds with caries progression. The MS strains isolated in this study or their main glycolytic metabolism connected with PK enzymes might be useful risk fa...

OBJECTIVE To provide a brief commentary review of strategies to control dental caries. Dental decay is one of man's most prevalent diseases. In many counties, severity increased in parallel with importation of sugar, reaching its zenith about 1950s and 1960s. Since then, severity has declined in many countries, due to the wide use of fluoride especially in toothpaste, but dental caries remains ...

The dentifrices currently available in the marketplace contain many anticariogenic substances, fluoride and abrasives aimed to better clean the dental surface, remove dental plaque, improve salivary flow and its buffer capacity and reduce colonies of bacteria such as S. mutans, the causative agent of dental caries. The objective of this study was to evaluate the possibility of adequately removi...

The purpose of this study was to determine if intraoral scanners (IOS) are useful for dental hygiene instruction. plaque eight volunteers with healthy dentition stained a plaque-disclosing solution, and the O’Leary Plaque Control Record (PCR) measured by direct observation evaluating IOS images. PCR values were higher images than observation. difference greatest lingual surface mandibular anter...
