What is dehiscence of bone?
What is bone dehiscence? Dental dehiscence in bone is a condition when the bone of your tooth wears away below the gumline. This exposes the tooth’s root (there is no marginal bone loss with dental fenestration). The outline of the root appears like a cylinder and you may see it protrude beneath the gumline.
What is alveolar bone dehiscence?
Hence, in our study, an alveolar bone dehiscence was defined as a bony defect of the alveolar unit that appears as a V-shaped defect along the alveolar bone apically, lacks a margin and is located on the buccal or lingual side of a tooth.
What is dehiscence and fenestration?
Dehiscence is the incomplete coverage by bone over an area of a root that includes the cemento-enamel junction. Whereas fenestration is a window of bone loss which exposes the root surface to the gingival or alveolar mucosa. The fenestration is bordered by alveolar bone on the coronal surface.
What is buccal fenestration?
In dentistry, a fenestration is a buccal or lingual window defect of either denuded bone or soft tissue occurring over a tooth root, implant, or alveolar ridge. The term may also apply to a man-made fenestration which is created when opening a lateral window to the maxillary sinus for a sinus augmentation procedure.
Can canal dehiscence be cured?
The most common treatment options are: Resurfacing, or more commonly today, plugging of the dehiscence from the middle cranial fossa approach. Plugging of the dehiscence from the mastoid approach. Reinforcement of the round window membrane.
How do you treat fenestration?
Various treatment modalities advocated in the literature for the management of mucosal fenestrations are lateral pedicle flap, Guided Tissue Regeneration (GTR) and apicoectomy combined with endodontic treatment.
What causes dehiscence?
The causes of dehiscence are similar to the causes of poor wound healing and include ischemia, infection, increased abdominal pressure, diabetes, malnutrition, smoking, and obesity.  Superficial dehiscence is when the wound edges begin to separate and by increased bleeding or drainage at the site.
How long does dehiscence take to heal?
How is dehiscence treated? The average time for an abdominal incision to fully heal is roughly 1 to 2 months. If you think your wound may be reopening, or if you notice any symptoms of dehiscence, contact your doctor or surgeon immediately.
What is the medical term for root dehiscence?
root dehiscence. root de·his·cence. a loss of the buccal or lingual bone overlaying the root portion of a tooth, leaving that area covered by soft tissue only.
How is bone dehiscence different from dental fenestration?
Sometimes confused with dental fenestration, bone dehiscence affects the length of the bony aspect of the tooth. In both fenestration and dehiscence, only the periosteum (connective tissue that overlays the tooth) and a thin layer of gum tissue covers the tooth’s root. With dental fenestration there is still bone at the coronal end of the tooth.
What does dental dehiscence do to your teeth?
Treatment for dental dehiscence treatment aims to cover the exposed tooth root to stimulate gingival repair and bone regrowth. Your dentist can achieve some degree of coverage for the exposed root, regardless of the class of your gum recession.
When does dehiscence cause a gingival recession?
Whenever bone loss is limited to a single tooth surface, usually the buccal one, bone defect is best known as dehiscence (Figs 5, 6 ). Over time, normal or inflamed gingival soft tissues tend to keep up with cervical bone levels; therefore, gingival recession is established.
