December, 2005. |
| Composite
resin restoration is missing from tooth 4.5. No caries. No
sensitivity. Discolouration is from a pre-existing silver
amalgam. |
|
Tooth
4.5 has been restored with bonded composite resin.
No local anaesthetic was needed.
|
| If
tooth or composite resin should fracture in the future, crown
or onlay-inlay made with porcelain (with or without metal
substructure) could be made, as a larger, stronger restoration.
However, the previous composite resin lasted for 18 years,
with no deterioration of the tooth. The new composite might
last a long time again

| Radiograph
shows upper porcelain-on-metal bridge, made in November, 1993,
and porcelain-on-metal crown on lower molar, made in July,
1993. |
|
Upper
bridge, lower crown, and 4.5 composite resin are all still
doing well. |
In 1995, molar 4.7
was extracted, but roots fractured. Larger distal root and smaller
mesial root tip were left in place, rather than do more extensive
surgery. The site was comfortable in 1996.
|
|
4.7 retained roots
are not yet causing symptoms. |
| The composite resin restoration
in lower bicuspid 4.5 was placed in July, 1987, by Dr. Perlmutter
& expanded-duty hygienist Sharon. |
|
The loss of this 4.5 restoration
in December, 2005, could be considered a failure, or it could
be considered an 18-year success, especially since the tooth
itself did not deteriorate. |

Distal root of 4.7 was extracted,
July, 2005. In December, 2005, 4.7 site is comfortable and healthy.
Retained mesial root tip has not caused
any problems. |

30 years by Dr. Mel Perlmutter.

-
Bridge – This was made primarily
for appearance. The upper right bicuspid, 1.4, had been
extracted before 1975. The stable occlusion prevented
drifting of teeth. I did not tell the patient she “needed”
this bridge.
-
Surgery – Extraction of lower molar
4.7 resulted in 2 roots fracturing. Usually it is best
to remove both fractured roots immediately. However, sometimes,
the extra surgery of removing bone to access the roots
can be detrimental. Here we have an example where the
long-term result of leaving the roots in place did NOT
harm the patient. Removing the distal root in 2005 was
a much simpler surgical procedure than it would have been
in 1993.
