AIM The aim of this pilot study was to evaluate the effectiveness of a mouthwash containing Triclosan and Gantrez in the reduction of bacterial biofilm and gingivitis. METHODS AND MATERIALS Thirty patients were assigned to control and experimental groups. The visible plaque index and the marginal bleeding index were determined at the baseline, and at the second and third months, at which time...

OBJECTIVES The aim of this study was to identify changes in the oral environment with clinical, salivary and bacterial risk markers after placement of fixed orthodontic appliances on permanent dentition. MATERIAL AND METHODS With ethical approval, we used different techniques to analyzed clinical, salivary and bacterial risk markers in 34 patients (mean age, 16.7+5.2 years), 14 males and 20 f...

Periodontal disease is the most widespread oral disease in dogs which if left untreated results in significant pain to the pet and loss of dentition. The objective of this study was to identify bacterial species in canine plaque that are significantly associated with health, gingivitis and mild periodontitis (<25% attachment loss). In this survey subgingival plaque samples were collected from 2...

OBJECTIVES To determine the effectiveness of a motivational interviewing-based educational program in reducing the number and intensity of new caries and bacterial dental plaque levels at 6 months post randomization. STUDY DESIGN A randomized and single blind clinical trial in 100 schoolchildren between 6-10 years of age presenting the highest risk score of caries according to the Caries Mana...

Certain forms of dental decay and periodontal disease appear to be due to specific bacterial infections following overgrowth of certain indigenous plaque bacteria, i.e., the specific plaque hypothesis. If so, then antimicrobial treatment based on a diagnosis of elevated levels or proportions of these organisms shiould be considered. Such treatment cannot be administered according to concepts of...

BACKGROUND Over 700 bacterial species reside in human oral cavity, many of which are associated with local or distant site infections. Extensive characterization of the oral microbiome depends on the technologies used to determine the presence and proportions of specific bacterial species in various oral sites. OBJECTIVE The objective of this study was to compare the microbial composition of ...

Periodontitis and caries are infectious diseases of the oral cavity in which oral biofilms play a causative role. Moreover, oral biofilms are widely studied as model systems for bacterial adhesion, biofilm development, and biofilm resistance to antibiotics, due to their widespread presence and accessibility. Despite descriptions of initial plaque formation on the tooth surface, studies on matur...

Gingival lesions not induced by plaque are common and can help explain the many different periodontal tissue reactions observed. Gingival inflammation sometimes differs from that of routine plaque-associated gingival diseases and often presents distinctive clinical features. (Holmstrup, 1999a). The causes of non-plaque-induced gingival diseases include bacterial, viral, and fungal infections, g...

This article briefly discusses the antibacterial action ofcetylpyridinium chloride (CPC) and its efficacy in the removal of bacterial plaque as an adjunct to the mechanical cleaning of tooth surfaces. It reviews new studies on the effectiveness of mouthwash formulations containing CPC against two common oral bacteria species and in disrupting plaque biofilms. Finally, this article reviews three...

One of the most significant advances in oral microbiology in recent years is advanced imaging methodologies to reveal the geography of oral biofilms. Although the revolution in bacterial sequencing has left us with an unprecedented abundance of data regarding the diversity and abundance of bacteria in caries and periodontal diseases, detailed information on the organization of dental biofilms i...
