Taking into account these three characteristics, it may be proposed that APE is characterized at DGU level by a long junctional epithelium, since the gingival sulcus appears normal and the biological length is prolonged, with a short connective tissue attachment – since the distance from crest to cementoenamel junction is short. Radiographic analysis of alveolar crest height and age. The red line indicates the proportion of cases with APE for overlap values greater than or equal to that indicated on the abscissas axis.

It describes the dimensions and relations of the different elements of the dentogingival unit. Measurement of thickness of connective tissue attachment and free gingival thickness Click here to view. Diagnosis and classification of delayed passive eruption of the dentogingival junction in the adult. Gutta-percha cut appropriately Click here to view. The study sample was divided into two groups: Probe depth in mm was evaluated at three points on the vestibular aspect of each of the sextant teeth.

The mucogingival junction is apical to the alveolar crest. Intrasulcular margin placement must be accepted as inevitable.

Our own results support this notion. J Clin Periodontol ;4: Thus, the PPRx technique offers a simple, concise, noninvasive, and reproducible method that can be used in the clinical setup to measure both the length and thickness of the DGU with accuracy. Indian J Dentogingivql Res ; Although these two morphological types are seen in clinical practice, it is difficult to establish whether they are effectively attributable to the two proposed mechanisms.

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

Changing concepts of the supporting dental structures. This article has been cited by other articles in PMC.

No xentogingival correlation was recorded between teeth 21 with and without APE in: The pattern and control of eruptive tooth movements. The role of the roentgenogram in the diagnosis and prognosis of periodontal disease.

An excessive amount of gingiva covering in the occlusal direction of the anatomic crown can be noted. No significant differences were observed between the presence sentogingival tooth 21 with APE and the clinical variables age and sex, Angle molar and canine occlusion class, lip-nose distance and probe depth.

A total of individuals participated in the study. In this way APE of tooth 21 is defined according to percentage overlap.

The mean biologic width by trans-gingival probing was 1. This study was undertaken to evaluate an innovative radiographic exploration technique parallel profile radiography [PPRx] for measuring the dimensions of the DGU on the labial surfaces of maxillary anterior teeth and to provide additional information on the dimensions of the DGU in humans.

The PPRx allows us to measure discrepancy and the degree of overlap 4.

Therefore, in our series of teeth, attrition was scantly relevant to crown length. Clinical exploration Two subjective criteria were contemplated for the clinical diagnosis of APE: Some authors indicate that gingival sulcus probe depth is important for the diagnosis of APE, and claim that depths of over 3 mm without concomitant pathological signs are suggestive of APE 10 Walter Reed Army Medical Center; This vertical motion causes the gums to displace along with the crown.

Our own results support this idea. These results coincide with the hypothesis postulated by Coslet 6 and posteriorly evaluated by Amsterdam, who explained these two morphological situations in terms of eruption arrest in either the passive or active phase. 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. On the relationship between crown form and clinical features of the gingiva in adolescents.

Transgingival probing trans-sulcular was done for these same patients and length of the DGU was measured. Lead foil cut appropriately Click here to view.
