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.
