Microscopes

Microscopes are particularly useful in dentistry for various purposes such as diagnosis of subgingival deposits, microfractures, longitudinal fractures, defective marginal fit of restorations and other things that can be overlooked clinically. In addition, magnification is often necessary to study root canal anatomy and the root surface in endodontics.
In general magnification can be set to between 4x and 24x, thereby expanding the diagnostic options due to better lighting and sight.
When coupled with the appropriate capture devices, microscopes can become instruments capable of projecting and recording clinical procedure in a more streamlined and efficient manner.

Introducing Microscopes

There are five key areas in which microscopes offer distinct advantages and benefits to the clinician:

  • Magnification
  • Illumination
  • Precision
  • Visualisation
  • Ergonomics

Magnification: this is determined by the power of the eyepiece, the focal length of the oculars, the magnification changer and finally the focal length of the lens.

Microscopes normally provide between 3x and 30x magnification with the ability to change views. Microscopes offer a deeper depth of field of view and a wider field of view than dental loupes.

Illumination: When magnification is used, the available light is spread out and the image appears darker. To compensate for this, an LED light, mounted directly on the microscope head provides a bright, white light.

Precision: Increased targeted magnification using a microscope enables dentists to see the treatment area in great clarity and therefore aids the completion of detailed work.

Visualisation: Dentists can only treat what they see. When using a microscope, the lens can be positioned directly over the patient’s mouth without any additional discomfort either for patient or clinician.

Ergonomics: When using a microscope dentists can be seated, which means a more comfortable working environment, particularly for longer procedures.


Microscope Applications


The benefits of microscopes are many and varied and have applications across a range of dental disciplines.


  • Restorative Dentistry:

    • Provides refinement in tooth and margin preparation
    • Allows for closer inspection of restorations and marginal tissues
    • Helps with inspection of marginal fit of the restoration
    • Improved lighting and magnification help with caries detection and removal
    • Improves detection and evaluation of coronal and root fractures and other abnormalities
    • Facilitates cord placement for gingival retraction
    • Enables better inspection of impressions
    • Assists in gingival contouring or reshaping around teeth and implants

  • Endodontics:

    • Improves visualisation of fracture patterns, both of the coronal aspect of the tooth, the chamber, and into the root structure.
    • Enables the isolation, evaluation, and remediation of pulpal chamber obstructions, calcifications, and resorptions
    • Enables predictable pulp chamber visualisation
    • Three-dimensional visualisation of root obstruction from separated instruments allowing for the successful removal of blockages
    • Enables the thorough cleaning of deep caries, which can be completely illuminated, removed, and sealed
    • Easier manipulation of gingival tissue
    • Reduces operator fatigue and eyestrain during procedures

  • Periodontics:

    • Clinician can minimize the size of the surgical site, reducing patient discomfort and healing time
    • Improves accuracy of microsurgical incisions and suturing
    • Allows for better inspection and diagnosis of abnormal soft tissue lesions
    • Aids identification of micro-inflammation following non-surgical therapy
    • Helps inspection of the quality of restorations and marginal tissues
    • Improves visualisation of implant sites and helps in evaluating the exact fit of prosthetic components
    • Permits precise control of laser surgery
    • Facilitates sinus lift procedures through direct visualisation of the sinus membrane during dissection
    • Provides upright working conditions, alleviating neck, back and shoulder problems

  • Prosthodontics:

    • Easy diagnosis of microscopic cracks in teeth
    • Enables micro adjustments of crowns and bridges during ‘try-in’
    • Useful in the finishing and polishing of the final edge of prostheses
    • Aids the achievement of high quality aesthetic outcomes
    • Enhanced visualisation simplifies complicated treatments

  • Surgical:

    • Powerful magnification can be used to examine very fine details for diagnostics and intrasurgical examinations
    • Postural, procedural, psychological and educational benefits for clinicians and patients
    • Enables clear vision to aid all surgical treatments, including implants, impacted teeth and soft tissue grafting
    • Of particular value in the surgical treatment of injuries and lesions in the sensitive area of the mouth, including lingual nerve and lower jaw nerve
    • Procedures using microscopes involve less operative trauma and therefore improved healing and outcomes

Which Microscope is right for me?


Kaps 900

The Kaps 900 is a high performance and user-friendly dental microscope. It supports the dentist’s routine work and is a perfect entry level model with an attractive price-performance ratio.

  • Brilliant Optics

    Kaps optics deliver crystal-clear images and high resolution details in natural colours (apochromatic optics).

  • Integrated LED Lighting

    The high-contrast colour temperature of the LED lighting strongly resembles daylight. In addition, the even lighting of the field of vision makes work less tiring. Further advantages include the long durability (50,000 hours) and low electricity consumption. The LED lighting is noiseless and generates minimum heat.

  • Ergonomics

    With the Kaps 900, clinicians are always seated comfortably in an ergonomic upright position, resulting in a much more relaxed approach to clinical work.

    • 5-step magnification changer
    • 0-210° inclinable binocular tube f = 182 mm
    • Objective f = 250 mm, with fine focussing
    • Eyepieces 12.5 x V
    • Integrated LED-illumination, dimmable (operating time circa. 50,000 hours)
    • Space-saving mounting systems
    • Ergonomic hand grips

  • Mode Control

    The ZEISS EXTARO 300 allows you to activate all visualisation modes and camera functionalities without taking your eyes off the surgical field. With only one finger, clinicians can reach the multifunctional Mode Control to activate all visualisation and capture modes, as well as light settings. From the same hand position, you can adjust the focus without leaving your preferred working position.

  • Fluorescence Mode

    This helps you to preserve as much of the healthy tooth substance as possible. It also supports you in distinguishing natural hard tooth tissue from the most widely used dental composite resin. Using this clear visual differentiation will help you to target the affected area quickly, saving you valuable chair time during excavation.

  • NoGlare Mode

    This allows for precise analysis a tooth shade. It effectively suppresses obtrusive light reflections from the tooth surface and prevents premature composite curing while working in a natural light environment.
