Dental plaque has been suggested as a reservoir for Helicobacter pylori but the hypothesis that the oral microflora may be a permanent reservoir of H. pylori is still controversial. The aims of this study were to determine the presence of H. pylori DNA in the gastric antrum and dental plaque of a Venezuelan population by PCR and to investigate the relationship between this infection and the ora...

OBJECTIVE To evaluate the dental status of 88 cancer patients before chemotherapy. MATERIAL AND METHODS Eighty-eight patients with cancer in different body locations were studied and compared with a control group. Dental plaque was assessed by means of the Silness and Löe index, dental status with the DMFT index, and periodontal status with the modified CPI index. RESULTS In the oncological...

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...

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 ...

INTRODUCTION During critical illness, dental plaque may serve as a reservoir of respiratory pathogens. This study compared the effectiveness of toothbrushing with a small-headed toothbrush or a foam-headed swab in mechanically ventilated patients. METHODS This was a randomised, assessor-blinded, split-mouth trial, performed at a single critical care unit. Adult, orally intubated patients with...

BACKGROUND Chlorhexidine (CHX) as a gold standard chemical agent appears to be the most effective antimicrobial agent for reduction of both plaque and gingivitis. The aim of this study was to compare the efficacy of two concentrations of digluconate chlorhexidine (CHX) solutions (0.12% and 0.20%) on gingival indices and the level of dental staining during 14 days. MATERIALS AND METHODS in thi...

Objective: The purpose of the study is to assess and compare the plaque and gingival status among dental students undergoing orthodontic treatment with that of non-orthodontic treatment.
