Introduction: Oral changes during pregnancy can lead to serious complications if left untreated. Pregnancy is a good time to educate women. Health Belief Model (HBM) is one of the best models for disease prevention. Therefore, this study was conducted with the aim of developing and evaluating a a HBM-based educational program on oral hygiene behaviors among child-wanting women in Mehriz, Yazd ...
Genes are transferred between bacteria in dental plaque by transduction, conjugation, and transformation. Membrane vesicles can also provide a mechanism for horizontal gene transfer. DNA transfer is considered bacterial sex, but the transfer is not parallel to processes that we associate with sex in higher organisms. Several examples of bacterial gene transfer in the oral cavity are given in th...
Micro-organisms isolated from the oral cavity may translocate to the lower airways during mechanical ventilation (MV) leading to ventilator-associated pneumonia (VAP). Changes within the dental plaque microbiome during MV have been documented previously, primarily using culture-based techniques. The aim of this study was to use community profiling by high throughput sequencing to comprehensivel...
The formation and composition of dental plaque biofilm in vivo are important factors which influence the development of gingivitis, caries and periodontitis. Studying dental plaque biofilm in in vitro models can cause an oversimplification of the real conditions in the oral cavity. In this study, bovine enamel slabs were fixed in an individual acrylic appliance in situ to quantify dental plaque...
PURPOSE Mechanically ventilated patients are at risk for developing ventilator-associated pneumonia, and it has been reported that dental plaque provides a reservoir of respiratory pathogens that may aspirate to the lungs and endotracheal tube (ETT) biofilms. For the first time, metataxonomics was used to simultaneously characterize the microbiome of dental plaque, ETTs, and non-directed bronch...
OBJECTIVE To compare the therapeutic effects of the application of doxycycline-full dose (100 mg) and sub-dose (20 mg) in the treatment of periodontal disease. MATERIAL AND METHODS A total of 60 patients with periodontal disease were examined. Patients are divided into two groups: A) treated with antimicrobial dose of 100 mg doxycycline once daily for 30 days, and B) treated with 2 x 20 mg/da...
OBJECTIVE To isolate Helicobacter pylori (HP) from the dental plaque of a selected group of children and to compare the oral and salivary findings of patients with those of a healthy control group. METHODS A total of 70 children aged 5-15 years were included in this study. An intraoral examination was performed for each patient, and dental plaque and saliva specimens were collected for analys...
introduction: one of the most common problems we confront in orthodontic therapy is periodontal diseases. initial factor which causes these diseases is colonization of anaerobic microorganisms in subgingival plaque. technically, local environmental changes related to orthodontic band and brackets may influence the bacterial species in periodontal plaque. however, it seems necessary to assess va...
BACKGROUND Chewing-gum may serve as an effective oral hygiene device when brushing may not be possible. The aim of the present study was to evaluate the effect of chewing sugar-free gum twice a day after meals in addition to tooth brushing on dental plaque and interdental debris. METHODS Twenty four (12 males and 12 females aged 20-21 years) healthy third-year dental students participated in ...
