Our endodontic office is equipped with sophisticated OPMI
Endodontic treatments can be very challenging due to the
complexity of the anatomy of the root canal system. In the past root canal
treatment was performed predominantly by feel. With the aid of the OPMI,
structures can be seen that remain hidden to the naked eye and treatment can be
carried out with far greater precision and predictably than ever before.
Microscopy in endodontics has become a way of life.
Uses of the OPMI in endodontics:
Identification of internal cracks
The dentist should always look for internal vertical coronal
and radicular cracks and fractures when using the OPMI. These would be
difficult or impossible to detect without the high magnification and
illumination provided by the OPMI.
The root canal anatomy of teeth can be very variable and
missed canals are a major cause of failure of root canal treatment. The OPMI
plays a vital role in helping to identify accessory canals at whatever level
they may be. Commonly missed canals are the MB2 canal in maxillary molars and
to a lesser degree, the mid-mesial canal in mandibular molars, buccal canals of
lower incisors and second and third canals in premolars.
Endodontic root-end surgery
Thanks to the improved visualization provided by the OPMI
along with microsurgical instruments, this procedure can be performed much more
conservatively. For instance, the amount of apical bone removal/osteotomy size
does not need to be large when using the OPMI. Hence, the procedure could be
considered as minimally invasive. • The smaller apical osteotomy / access
improves hard-tissue healing and success rates. • The OPMI enables the dentist
to locate isthmuses (often infected) joining adjacent canals (ie isthmus
between MB1 and MB2 in maxillary molars or MB and ML canals in lower molars) •
The OPMI enables the identification of fractured instruments at the root
apex.• Using an OPMI enables the dentist
to diagnose/locate root-end microfractures. •
Root-end canal preparation can be done more precisely and conservatively
with use of micro-ultrasonic tips made specifically for surgery. For this, one
should use high magnification and high illumination. • Flaps are improved with the ability to make
incisions more precisely with micro-scalpels. •
Suturing under the OPMI should be more precise and less traumatic. This
is made possible since very fine sutures (i.e. 6-0) could be better visualized
under the OPMI. This is especially important in the aesthetic area.
The benefits of the OPMI extend far beyond the obvious and
well-proven clinical benefits.
Many of the procedures highlighted could not be performed
without the OPMI and therefore it enables the clinician to offer many more
treatments than would otherwise be possible.
Having more control of the clinical environment can lead to
greater efficiency (i.e. reduced time looking for sclerosed canals), less
stress and more predictable outcomes.
Patients rapidly come to understand that a dentist using the
OPMI is working at the very highest standards of the profession and with the
ability to document, this greatly increases acceptance of treatments.
The use of the image capturing capabilities of the OPMI
provides a powerful communication tool. Whether it is with still or video
images, showing patients the state of their oral health makes it easier for
them to understand the problem at hand. It is easier for patients to agree to
treatment when, for instance, they are shown a closeup of a faulty restoration
margin and are recommended to have it replaced. Acceptance of treatment would
be reduced if it were only discussed verbally. The OPMI can therefore help to increase acceptance rates and treatment fees.
A picture is worth a
thousand words and this is very significant when it comes to record keeping.
For instance, not only is it easy to diagnose hairline fractures, but it is
also easy to record them in the patient’s chart.
