The biologic width appears dentogingical exist in any periodontium, and the importance of not violating this physiologic dimension was suggested by Ochsenbein and Ross 9 and stressed by other authors.

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 Galgali SR, Gontiya G. Invasion of this space triggers inflammation and causes periodontal destruction. National Center for Biotechnology InformationU.

In this way APE of tooth 21 is defined according to percentage overlap. Measurements were also obtained of the biological width, the distance from the cementoenamel junction to the jnit, the thickness of the free gingival at the base and middle-third, discrepancy, and gingival overlap 4.

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

J Clin Periodontol ;4: J Periodont Rest Dent ; How to cite this URL: The PPRx allows us to measure discrepancy and the degree of overlap 4. Proc R Soc Med. University of Amsterdam; J Clin Periodontol ; 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.

The keratinized gingival width was measured on each tooth.

In humans this distance is 2. The clinical picture is then characterized by the recession of the gingival margin or the retention of the original level and a deepening of the pocket. This clinical situation presents, on the buccal level, similarities to that described in Figand suggests treatment possibilities. Clinical diagnostic criteria of altered passive eruption APE. We thus raise the hypothesis that APE implies relative failure to fully complete tooth eruption, conditioned by two types of mechanisms: Pathogenesis of Periodontal Disease and its Treatment.

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. J Clin Periodontol ; Walter Reed Army Medical Center; The protocol 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.

No significant differences were observed unnit the presence of tooth 21 with APE and the clinical variables age and sex, Angle molar and canine occlusion class, lip-nose distance and probe depth. This study define altered passive eruption APE and evaluate the morphology of the dentogingival unit. Our own results support this idea.


The DGU is habitually located close to the cementoenamel junction, the gingival margin slightly covering the limits of the dental crown 5. If the mechanism of eruption were the sole responsible factor, it would be logical to assume denogingival with active tooth eruption failure, some patient in the series could present a zero or even negative distance, as a result of burying of the tooth within the alveolar bone.

The precision of the technique was then evaluated by performing the dentigingival in duplicate – each time completely dismounting and again mounting all the pieces of the paralleling system total: Thickness of gingival obtained by PPRx technique Click here to view.

Introduction The dentogingival unit DGU has been described as a functional unit composed of the epithelial attachment and connective tissue attachment of the gingiva — both of which afford biological protection 1.

In a healthy state, the gingival margin is generally located on the enamel and the junctional epithelium from the base of the sulcus to the CEJ, and the gingival fiber apparatus takes place between the osseous crest and the CEJ. A geometrical evaluation of image size in dental radiography. As age progresses the epithelium is apt to proliferate in an apical direction.
