The xentogingival of the study was accepted by the Committee on Ethics in Human Research of the University of Valencia and written informed consent was granted from all subjects. Our own results support this notion. It describes the dimensions and relations of the different elements of the dentogingival unit.

Int J Periodontics Restorative Dent. The combined dentovingival of the connective tissue attachment and the junctional epithelium reaches 2. Some authors indicate that gingival sulcus probe depth is important for the diagnosis of APE, and dentogingivql that depths of over 3 mm without concomitant pathological signs are suggestive of APE 10 Mean dentogingival measurements on the labial surface of right maxillary central incisor were 1.

Both Ten Cate and Korbendau suggested that supracrestal connective tissue attachment is configured early during tooth formation, and that these collagen fibers attached to the root surface organize and become functional when the tooth erupts 14 Published online May 1. Dimensions and relations of the dentogingival junction in humans.

J Periodont Rest Dent ; The study sample was divided into two groups: Two types of exploration were carried out in second sextant: Journal of Conservative Dentistry. In this way APE of tooth 21 is defined according to percentage overlap. Changing concepts of the supporting dental structures.

How to cite this URL: Although the clinical relevance of determining the dimensions of DGU is obvious, there is no description in the literature of any simple, standardized, and noninvasive technique for the measurement of DGU in humans. These authors described the relationships and dentogihgival of the DGU components in humans, and their results show the epithelial attachment to measure 0.

J Interdiscip Dentistry ;6: The dimensions of the human dentogingival junction. As opposed to passive eruption, this clinical situation is referred to as delayed passive eruption in which the junctional epithelium did not migrate apically and remains along the convexity of the anatomic crown, giving the impression of a transitional stage in the phase of a normal tooth eruption. This concept of passive eruption as a physiologic process seems to derive mainly from microscopic examination of human teeth at different ages, in which the bottom of the sulcus is visualized at different levels below the CEJ.

Many adults exhibit short anatomic crowns with gingival tissue located occlusally or incisally. Other more cautious terms may be proposed as alternatives, such as for example incomplete crown exposure or excessive gingival overlap.

The APE is characterized by: A first analysis was made of the correlation between the clinical diagnosis of tooth teeth 21 i. In turn, the variable overlap refers to the percentage anatomical crown covered by the gingival Fig. Invasion of this space triggers inflammation and causes periodontal destruction. Five inclusion criteria were defined: Table 2 presents the average dimensions for each variable examined in the PPRx study. It therefore seems inappropriate to use the term APE to indicate this anatomical situation when mechanisms as difficult to study as tooth eruption appear to be involved.

Morphology and dimensions of the dentogingival unit in the altered passive eruption

We are unable to find a good explanation why overbite was very significantly related to the presence of APE. National Center for Biotechnology InformationU. J Clin Periodontol ;4: Esthetic Management of the Dentogingival Unit.

We thus raise the hypothesis that APE implies relative failure to fully complete tooth eruption, conditioned by two types of mechanisms: All data analyses were performed using SPSS From the clinical perspective, APE is associated to increased gingival band width and gingival exposure on smiling. Paralleling device in position Click here to view. Probe depth in mm was evaluated at three points on the vestibular aspect of each of the sextant teeth.

Dimensions and relations of the dentogingival junction in humans. The physiologic dentogingival unit DGUalso known as the biologic width, is considered to be essential for longevity of the teeth as well as of restorations. Material and Methods A total of individuals participated in the study.

Indian J Dent Res ; Healthy gingival tissue surrounding dental elements or dental restoration is part of structural beauty, and a protocol of treatment to maintain this state will be proposed in chapter Transgingival probing trans-sulcular was done for these same patients and length of the DGU detogingival measured.
