The average concentration of dental plaque microorganisms in an adult with average condition of oral hygiene is about 2.5 X 10cells/g. The marginal gingiva alone harbours more than 325 cultivable bacterial species [1]. Up till a decade ago, an estimated 50% of the bacterial cells in plaque were yet to be cultured [2]. Most forms of oral diseases occur because of excessive accumulation of plaque...

Dental biofilms that form in the oral cavity play a critical role in the pathogenesis of several infectious oral diseases, including dental caries, periodontal disease, and oral candidiasis. Houttuynia cordata (HC, Saururaceae) is a widely used traditional medicine, for both internal and external application. A decoction of dried HC leaves (dHC) has long been consumed as a health-promoting herb...

Maintenance of proper oral hygiene by dental plaque elimination is one of the most important factors affecting the healing process in postoperative oral wounds. Propolis is a substance produced by bees. Ethanolic extract of propolis has bactericidal, fungicidal, anti-inflammatory, and antioxidative properties. Moreover, it can scavenge free radicals. The purpose of this paper is to demonstrate ...

The aim of this study was to evaluate the microbial distribution in the root canal system after periapical lesion induction in dogs' teeth using different methods. Fifty-two root canals were assigned to 4 groups (n=13). Groups I and II: root canals were exposed to the oral cavity for 180 days; groups III and IV: root canals were exposed for 7 days and then the coronal openings were sealed for 5...

The morphology and cultural characteristics of bacteria of the Simonsiella genus isolated from erosions of oral mucosa are reported here. Direct microscopic examination of smeared oral swabs and the consequent selection of suitable culturing procedures and media are compulsory for recovering Simonsiella microorganisms from clinical specimens in routine work.

Objective—The objective of this study was to determine the prevalence of select microorganisms in oral biofilms and to investigate relationships between oral and respiratory status in persons with mental retardation/intellectual and developmental disabilities (IDD). Study Design—We conducted a 6-month-long observational cohort study with 63 persons with IDD. Oral examinations, oral sampling, an...
