A flavonoids-free Brazilian
propolis (type 6) showed biological effects against mutans streptococci and inhibited the activity of glucosyltransferases. This study evaluated the influence of
the ethanolic extract of a novel type of propolis (EEP) and its purified hexane fraction (EEH) on mutans streptococci biofilms and
the development of dental caries in rats. The chemical composition of the
propolis extracts were examined by gas chromatography/mass
spectrometry. The effects of EEP and EEH on Streptococcus mutans
UA159 and Streptococcus sobrinus 6715 biofilms were analysed by time-kill and glycolytic
pH drop assays. Their influence on proton-translocating
F-ATPase activity was also tested. In the animal
study, the rats were infected with S. sobrinus 6715
and fed with cariogenic diet 2000. The rats were
treated topically twice a day with each of the extracts (or control) for 5
weeks. After the experimental period, the microbial composition of their dental
plaque and their caries scores were determined. The results showed that fatty
acids (oleic, palmitic, linoleic
and stearic) were the main compounds identified
in EEP and EEH. These extracts did not show major effects on the viability
of mutans streptococci biofilms. However,
EEP and EEH significantly reduced acid production by the biofilms
and also inhibited the activity of F-ATPase (60-65%).
Furthermore, both extracts significantly reduced the incidence of smooth surface
caries in vivo without displaying a reduction of the percentage of S. sobriuns in the animals' plaque (P < 0.05). However, only
EEH was able to reduce the incidence and severity of sulcal
surface caries (P < 0.05). The data suggest that the cariostatic
properties of propolis type 6 are related to its
effect on acid production and acid tolerance of cariogenic
streptococci; the biological activities may be attributed to its high content
of fatty acids.

Recently, two chemically different types of Brazilian propolis
(type-3 and -12) were shown to have cariostatic
properties. This study aimed to evaluate the influence of their isolated fractions
on mutans streptococci viability, glucosyltransferases (GTFs) activity
and caries development in rats. The ethanolic extracts
of propolis (EEPs) were
serially fractionated into hexane (H-fr), chloroform,
ethyl acetate, and ethanol. The ability of the four fractions and EEP to inhibit
Streptococcus mutans and Streptococcus sobrinus growth and adherence to a glass surface was examined.
The effect on GTFs B and C activity was also determined.
For the caries study, 60 Wistar rats infected with
Streptococcus sobrinus were treated topically twice
daily as follows: (1) EEP type-3, (2) H-fr type-3, (3) EEP type-12, (4) H-fr
type-12, and (5) control. In general, the H-fr from
both types of propolis showed the highest antibacterial
activity and GTFs inhibition. Furthermore, the EEP
and H-fr type-3 and -12 were equally effective in
reducing dental caries in rats. The data suggest that the putative cariostatic
compounds of propolis type-3 and -12 are mostly
non-polar; and H-fr should be the fraction of choice
for identifying further potentially novel anti-caries agents.

Propolis means a gum that is gathered by bees from various plants. It is known
for its biological properties, having antibacterial, antifungal and healing
properties. The aims of this study were to evaluate the antimicrobial activity
of four different Anatolian propolis samples on
different groups of microorganisms including some
oral pathogens and comparison between their chemical compositions. Ethanol
extracts of propolis (EEP) were prepared from four
different Anatolian propolis samples and examined
whether EEP inhibit the growth of the test microorganisms
or not. For the antimicrobial activity assays, minimum inhibitory concentrations
(MIC) were determined by using macrodilution method.
The MIC values of the most effective propolis (TB)
were 2 microg/ml for Streptococcus sobrinus
and Enterococcus faecalis,
4 microg/ml for Micrococcus luteus,
Candida albicans and C. krusei,
8 microg/ml for Streptococcus mutans,
Staphylococcus aureus, Staphylococcus epidermidis and Enterobacter aerogenes, 16 microg/ml for Escherichia
coli and C. tropicalis and 32 microg/ml for Salmonella typhimurium
and Pseudomonas aeruginosa. The chemical compositions
of EEP's were determined by high-temperature high-resolution
gas chromatography coupled to mass spectrometry. The main compounds of four
Anatolian propolis samples were flavonoids such as pinocembrin,
pinostropin, isalpinin, pinobanksin, quercetin, naringenin, galangine and chrysin. Although propolis samples
were collected from different regions of

[Evaluation of the
cario-static effect of Nidus vespae on biofilm model in vitro]

OBJECTIVE: To evaluate the Nidus vespae's
cario-static effect on biofilm
model in vitro. METHODS: A four-organism bacterial consortium was grown in
a biofilm model on hydroxyapatite
(HA) discs in a continuous culture system and exposed to repeated solution
pulsing respectively. There were three parallel-connected flow cells in the
model, so were the three groups with different solution pulsed in. Negative
control group was pulsed with distilled water, positive
control group was pulsed with 250 mmol/L sucrose
solution as well. While 4.0 g/L Nidus vespae together with 250 mmol/L
sucrose solution was pulsed in the experiment group. During the experiment,
the pH responses against the pulses were recorded. After the 6 pulses, the
biofilm surface structure was observed with a scan electron
microscope and the population on the biofilm was
enumerated. RESULTS: Nidus vespae
can significantly inhibit the adherence of Streptococcus mutans
to HA discs compared with the control group of 250 mmol/L
sucrose pulsed in, and can facilitate the remove of acid products. It is also
found that the extra-cellular polysaccharide is reduced with the pulsing of
Nidus vespae. CONCLUSION: Nidus vespae in the biofilm model can partially decrease the cariogenic response of sucrose solution pulsed in.

Propolis, a resinous hive product secreted by Apis mellifera bees, has been shown
to reduce the incidence of dental caries in rats. Several compounds, mainly
polyphenolics, have been identified in propolis. Apigenin and tt-farnesol demonstrated biological activity against mutans streptococci. We determined here their effects, alone
or in combination, on glucosyltransferase activity,
biofilm viability, and development of caries in
rats. Sprague-Dawley rats were infected with Streptococcus
sobrinus 6715 and treated topically twice daily
as follows: (1) tt-farnesol, (2) apigenin,
(3) vehicle control, (4) fluoride, (5) apigenin +tt-farnesol, and (6) chlorhexidine. Apigenin (

Antimicrobial activity of propolis on oral microorganisms.

Formation of dental caries is caused by the colonization and accumulation
of oral microorganisms and extracellular
polysaccharides that are synthesized from sucrose by glucosyltransferase
of Streptococcus mutans. The production of glucosyltransferase from oral microorganisms
was attempted, and it was found that Streptococcus mutans
produced highest activity of the enzyme. Ethanolic
extracts of propolis (EEP) were examined whether
EEP inhibit the enzyme activity and growth of the bacteria or not. All EEP

Propolis, the resinous hive product collected by
bees, is important in the defense of the hive. The
effects of propolis on growth and glucosyltransferase
activity of Streptococcus sobrinus 6715, Streptococcus
mutans PS14 and Streptococcus cricetus OMZ61 in vitro, and on dental caries in rats infected
with S. sobrinus 6715 were investigated. Propolis had antimicrobial activity against S. sobrinus, S. mutans and S. cricetus, and inhibited both water-insoluble glucan synthesis and glucosyltransferase
activity. In rats inoculated with S. sobrinus, about
half of their fissures were carious, while dental caries was significantly
less (p = 0.01) in rats given propolis. Dental caries
was markedly decreased by the multiple actions of propolis
which had antimicrobial activity, inhibited water-insoluble glucan
synthesis, and inhibited glucosyltransferase activity.
No toxic effects of propolis on the growth of rats
were observed under experimental conditions in this study. These results suggest
that propolis can control dental caries in the rat
model system.
