Furcation involvement hemisection root  resection molar tooth cavity decay dental caries bone loss Furcation involvement receding gum and bone loss in a mandibular molar tooth. How to pictures treatment of a molar in the lower jaw with a big tooth cavity decay: - root canal therapy. - gum surgery for crown lengthening. - two cast gold posts. - porcelain dental crown with a metal furcation.
furcation involvement subgingival decay tooth cavity below the gum caries teeth  recession receded The long term prognosis of a tooth dramatically decreases when there is furcation involvement. This is because the receding gum and bone loss exposes the underside of a mulitrooted tooth that is very difficult to keep clean. Therefore bacterial infection and dental caries and/or gum disease is much more likely without meticulous oral hygiene. This patient presented with an old tooth crown that had broken off a root canaled molar tooth. Preparation drilling into the pulp chamber revealed extensive subgingival - below the gum - tooth decay and furcation involvement. Tooth extraction is indicated.
furcation involvement hemisection tooth  teeth receding gums bone loss dental  gum recession gingiva How to pictures: Tooth crown removal and hemisection for a tooth with a furcation involvement. 1) Pre-op dental crown. 2) Initial preparation drilling through the crown. 3) Crown after removal. 4) Tooth after crown removal. 5) Preparation through composite core. 6) Gutta percha - the orange color - is root canal filling material. 7) Hemisection completed. Hemisection means cutting a two rooted tooth in half; it frequently also involves extraction of one of the two separate roots but not in this case. 8) Gutta percha is exposed and requires more dental composite resin to seal it within the tooth after crown lengthening periodontal gum surgery.

 Information about these dental photos

     In medicine and dentistry "left" and "right" are based upon the orientation of the patient's body and not how they appear in a photograph of a smile.  For example, a reference to the upper left teeth will actually appear to be on the right side when viewing a picture of the face and similarly an upper right tooth will appear to be on the left side.

     Many words in dentistry like oral and mouth have a similar meaning and are frequently used together to help our readers find specific words they best understand.  This is particularly important because a majority of our visitors are from countries where English is not their primary language.  Maxilla or maxillary refer to the upper jaw.  Mandible or mandibular refer to the lower jaw.

     There are many other similar word combinations used throughout this website because our pages are read by patients and dentists.  A few of the most common are discussed here.  Tooth decay, tooth cavity and dental caries all mean the same thing.  Tooth, teeth and dental are also frequently interchanged as in teeth veneers or dental veneer laminate.  Oral rehabilitation and dental reconstruction mean smile makeover.  The word for x-ray may be used with or without a hyphen (this is true for other words too) and can also be called a radiograph.
