1. GENERAL INFORMATION
1.1. Intended use: Dental photoactivator “Estus Light” is intended for
photopolymerization of composite light-cured filling materials
containing:
-the traditional photoinitiator camphorquinone, polymerizing in the
blue light spectrum in the range of 440-475 nm, and
- next-generation photoinitiators polymerizing additionally in the
ultraviolet light spectrum in the range 400-420 nm (for example,
“IVOCERIN” by “Ivoclar Vivadent”) during restoration work in the
patient’s oral cavity - the main purpose of the product.
The function is implemented using the polymerizing tips specified in
the table below:
The “ESTUS-BLUE POINT” tip allows to conduct the point
polymerization of photosensitive materials, for example, when
installing veneers. Also the tip is used for adhesive polymerization
inside the root canal at the stage of fixing fiberglass pins and for fixing
all-ceramic orthopedic structures, which allows to release paroxysmal
and cervical areas from the fixing material.
Additional “Estus Light” options when using special tips:
1. Transillumination - diagnostics of initial carious changes, hidden

carious cavities or defects, enamel cracks, quality control of
restoration and adaptation of composite materials to hard tooth tissues
using a light source emitting in the spectrum of orange light in the
range 585-595 nm. The function is implemented with the diagnostic
tip “ESTUS LED - ORANGE”.
2. Photodynamic therapy (PDT) - diagnosing the development of
malignant tumors in the early stages, conducting cancer cell therapy,
treating discoloritis when changing color of the elements of the
dentition, performing antibacterial and antifungal treatment of the
patient’s oral cavity using special photosensitive substances
(photosensitizers), activated by the source light emitting in the red
light spectrum in the range 620-645 nm (peak 630 nm) (for example,
tolonium chloride) or in the deep red light spectrum in the range 650-
670 nm (peak 660 nm) (for example “Photoditazine”).The function is
implemented with the therapeutic tips “ESTUS LED - RED 630” or
“ESTUS LED - RED 660” accordingly.
3. Luminescent diagnostics - diagnosing of some diseases of the oral
mucosa and tongue, contrasting of the old filling material, as well as
detection of bacterial deposits on the surface of the teeth using a light
source emitting in the ultraviolet spectrum in the range of 400-420 nm
(peak 405 nm). The function is implemented with the diagnostic tip
“ESTUS LED - LUMI”.
1.2. Indication for use: The device is intended for use in dentistry
during diagnostics, therapy and restoration work in the patient’s oral
cavity. The manufacturer is not responsible for any dangerous
situation while using the device for purposes other than that
intended.
1.3. Application field: The device is for use only in medical facilities.

USER’S MANUAL
www.geosoft.ru/en
1.4. Potential users: ONLY the licensed dentists.
1.5. Contraindications and adverse reactions: Without finding.
1.6. Contact type with a patient: Short invasive contact through the
oral cavity.
1.7. Operating principal:
1. Polymerization: The photoactivator of the polymerization process is
a powerful light source acting on the initiator of the polymerization
process as part of a composite material. The polymerization process
(curing) of the filling material occurs by local exposure with the
emitter.
2. Photodynamic therapy (PDT): The photosensitizer is input into the
oral cavity by the most suitable way, where it selectively accumulates
in pathogenic cells without affecting healthy tissue. The affected
tissue is then irradiated with a certain wavelength emitter. As a result
of the photochemical reaction, atomic oxygen is released that destroys
pathologically changed cells and inflammatory microflora.
3. Transillumination: The effect of transillumination is based on
differences in the ability to absorb light from different tissues and
materials. It is carried out with passing rays of light, by translucence
of the tooth crown from the palatine or lingual surface. The method is
based on the assessment of shadow formations that appear when a
cold light stream of orange color passes through a tooth and is
harmless to the body.
4. Luminescent diagnostics is based on the ability of tissues and their
cellular elements to change their natural color under the influence of
ultraviolet rays.
1.8. Functional abilities:
 Operation with 7 tips:
- 3 tips of the BLUE (“ESTUS LED - BLUE”, “ESTUS - BLUE

1 . 9 . Precautions and Warnings
!!Use the product with the original “Geosoft Dent” accessories only
(see section 3).
!Do not disassemble or modify the product. Violation of the device
integrity cancels the warranty.
!Avoid letting any liquid inside the product’s housing.
!Do not use the device close to flammable agents. The device is not
suitable for use in presence of flammable anesthetic agents with air,
oxygen or nitric oxide.
! Use cleaned and disinfected parts of the device only. Cleaning and
disinfection must be conducted directly before the initial use and also
between each patient use to avoid cross infection (for more details see
section 7).
!To avoid overheating and failure of the working tips of BLUE and
RED type the total continuous work period of the emitter should not
exceed 10 minutes.
!The light emission generated by the photoactivator when working
with tips such as BLUE and RED is dangerous for your vision. In
order to avoid direct and reflected emission from the light source
entering the eyes of the dentist, patient, and auxiliary personnel during
operation, the following should be done:
- to use special protective glasses with orange lenses for working with
the tips of BLUE type or the sunglasses for working with tips of RED
type.
- to switch on the photoactivator only in the patient oral cavity.
!The light emission generated by the photoactivator when working
with the tip of LUMI type is completely non-hazardous for your
vision at brief influence. Nevertheless, the following safety measures
should be adhered during operation:
- do not direct the light into the eyes of the dentist or patient,
- turn on the photoactivator only in the patient's oral cavity.
