Unique functions of hydroxyapatite with mutans streptococci adherence.
OBJECTIVE Hydroxyapatite (HA) is used as a construction material for artificial supplementation of enamel tooth surfaces to improve oral hygiene. This study examined in vitro HA interactions with mutans streptococci (MS) and bacterial adherence to small (nanosize) crystal form of HA beads having a protean hexagonal structure. The adsorption and physical effects of HA employed in vivo is also de...
متن کاملEffect of tongue cleaning methods and oral mutans streptococci level.
INTRODUCTION Tongue scraping and brushing have been appreciated for hundreds of years but are still appreciated or used by the public. Scientific evidence has validated the need to practice habitual and tongue cleaning as part of daily home oral hygiene procedures. OBJECTIVE To assess and compare the effect of tongue scraping and tongue brushing on oral Mutans streptococci level. MATERIALS ...
متن کاملDextranases from oral bacteria: inhibition of water-insoluble glucan production and adherence to smooth surfaces by Streptococcus mutans.
The effect of dextranases (EC 3.2.1.11) from the oral isolates Actinomyces israelii and Bacteroides ochraceus on water-insoluble glucan production by the Streptococcus mutans dextransucrase (EC 2.4.1.5) and sucrose-dependent adherence to smooth glass surfaces by S. mutans was studied. Collection on membrane filters of water-insoluble polysaccharides synthesized from radioactive sucrose was used...
متن کاملHydrophobicity test in mutans streptococci.
Kinetic hydrophobic measurements were performed by confronting 40 mutans streptococci from thirty 10- to 20-year-old patients with 200 ml hexadecane (Sigma). Fourteen patients had high dental caries risk (Group A), dmft + DMFT > 5 with 3 or more active caries, and 16 had low dental caries risk (Group B), dmft + DMFT < 3 without active caries. Twenty bacteria from Group A and 20 bacteria from Gr...
متن کاملMutans streptococci: acquisition and transmission.
Dental caries is an infectious and transmissible disease. The mutans streptococci (MS) are infectious agents most strongly associated with dental caries. Earlier studies demonstrated that infants acquire MS from their mothers and only after the eruption of primary teeth. More recent studies indicate that MS can colonize the mouths of predentate infants and that horizontal as well as vertical tr...
