Intended use
Dentocult LB is a dipslide culture method for
determining aerobic aciduric bacteria (i.e.lactobacilli)
in stimulated saliva. The concentration of lactobacilli
in saliva represent a caries risk factor.
Principle of the method
the Dentocult LB dipslide is covered on both sides
with modified Rogosa medium for culturing lactobacilli.
The selectivity of the medium is based on its chemical
composition and low pH. The medium allows the
growth of other oral aciduric organisms, such as yeasts
and streptococci.

Warnings and precautions
Dentocult LB is for IN VITRO DIAGNOSTIC USE only.
Do not use the product beyond the expiry date marked
on the box.
Do not use the product if you detect dehydration of
the agar medium, detachment of the growth media from
the plastic slide or evidence of bacterial or fungal growth.
Do not touch the growth on the agar medium.
Storage
Dentocult LB is stored at 7...25도 protected from
air and temperature fluctuations. Avoid draughts
and storage near heat-generating appliances.
DO NOT ALLOW TO FREEZE. The expiry date is
marked on the box.
Test procedure
1. Let the ptient chew a paraffin pellet for several
minutes (5min if saliva secretion rate is determined
simultaneously).
2.Collect the stimulated saliva in a vial or other
suitable vessel.
3.Unscrew the slide from the tube without touching
the agar surfaces.
4.Pour the collected saliva over both agar surfaces,
ensuring that they are well moistened.
If the saliva is very viscous, the sample can also be
applied using a sterile swab.
Saliva may also be sampled by pressing the agar
surfaces directly against the patient's tongue.
5.Allow excess saliva to drain from the slide.
6.Blot the last drops on absorbent paper.
7.Screw the slide tightly back into the tube.
8.Fili in the patient label and attach it to the tube.
9.Place the tube upright in an incubator
for four (4)days. To obtain a colony count
remove the slide from the tube and compare the
colony density on the agar surface with the model
chart provided in the kit
Note1.
If no incubator is available,the slide may be incubated
at room temperature for sevendays
Note2.
The test should be performed as soon as possible
after saliva stimulation.
Note3.
To avoid daily variation in Lactobaciilus counts, it is
best to take the samples before noon. If this is
not possible, samples from the same patient should
be taken at the same time of day during follow-up.
Note4.
Before sampling the patient should avoid
-eating for 1-3h
-drinking for 1-3h
-smoking for 1-3h
-tooth brushing for 1-3h
-antimicrobial mouth rinses for several hours
-tooth surface treatment for over two weeks
-antibiotiotic therapy for over two weeks
Interpretation of results
The presence of aciduric bacteria is evidenced by white
to transparent colonies on the modified Rogosa agar
surface. if the result appears to be negative, it should
be confirmed. the dipslide should be examined side-
ways under a bright light to detect colonies protruding
from the agar surface.
The bacterial growth may consist of both large and
small colonies. It is important to compare the colony
density with the model chart, irrespective of colony size.
Expected values
The presence of high numbers of lactobacilli (10
CFU/ml or higher) reflects a caries-inducing environ-
ment, indicating a high caries risk. The role of lacto-
bacilli in caries initiation is limited
Colony counts of>10000CFU/ml are considered high,
and counts of<1000CFU/ml are considered low
Carbohydrate intake is correlated with salivary
lactobacillus count in a mouth with no sites for micro-
bial retention.
High Lactobacillus counts are encountered in conjunc-
tion with low salivary secretion rate, low salivary
buffering capacity and the presence of glucose in
saliva.
Limitations of the procedure
In addition to lactobacilli, other aciduric oral microbes,
such as yeasts and streptococci, may grow on the
medium. Yeast colonies differ from Lactobacillus
colonies by being larger and nonshiny. Streptococci
typically grow as small colourless colonies on Dentocult
LB.

Quality control
Quality control tests are performed on each lot of
Dentocult LB tests at the time of manufacture. Should
the user wish to perform his own quality control, the
following procedure is recommended:
1.Prepare a 10-10 CFU/ml solution of each of the
following bacteria in sterile saline:
a.Escherichia coll ATCC25922
b.Lactobacillus plantarum ATCC8014
2.Use the suspensions to inoculate Dentocult LB
dipslides in the normal way
3.Interpret the cultural response after a four-day
incubation:
a.E.coli ATCC25922: no growth
b.L.plantarum ATCC8014: growth of large
whitish colonies
Disposal
Used Dentocult LB dipslides are best disposed of
by burning, autoclaving or immersing in a disinfectant
overnight, following local regulations.
