2020年7月5日 · Tooth root exposure which begins from the alveolar margin is dental dehiscence. Root exposure without alveolar margin involvement, looking like window-like root exposure, is called dental fenestration

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.

Gingival dehiscence is a condition where the bone of the tooth wears away below the gumline, exposing the root. The outline of the root appears like a cylinder, protruding beneath the gumline. This occurs most frequently on the facial surface of the tooth (the surface that faces forward).

Introduction: Fenestration and dehiscence are alveolar bone defects. Although not considered a pathology, these alveolar bone defects end up influencing dental treatment, such as surgeries, mainly periodontal, and therefore must be considered during treatment planning.

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. Figure 5.

2025年1月26日 · Dehiscence in dentistry refers to a specific type of bone loss that exposes the root of a tooth. This occurs when the alveolar bone, which normally surrounds and supports the teeth, recedes. Defining Dehiscence

The presence of dentoalveolar lesions such as fenestration and dehiscence has great clinical importance. This study was designed to determine the incidence of bony fenestrations and dehiscences associated with the anterior teeth by using …

In dentistry, the term is used to describe an entirely different process: the loss of alveolar bone on the front side of the tooth. This results in the appearance of an oval-shaped root-exposed defect underneath the gingiva. This condition is characterized by the degradation of alveolar bone, gum recession, and exposure of the tooth root.

Dehiscence may be defined as the apical migration of the alveolar margin bone from 2 mm since the cemento–enamel junction, and fenestration may be defined as the exposure of the root portion but excluding the alveolar margin bone from 0,5mm.

A dehiscence is defined as a V-shaped defect located along the alveolar bone margin (BM) toward the apex, and is located on the buccal or lingual side of a tooth (Leung et al., 2010). The aetiology of dehiscences can be attributed to many factors, such as tooth ectopia, root projection, periodontal inflammation, frenum attachments, root verti-
