Çukurova University

Status: Completed

Conditions: Gingival Recession

Study type: Observational

Funder types: Other

Identifiers

NCT02210143

CUDHF-2011-8-6

Details and patient eligibility

About

The aim of this study was to evaluate the reliability of the avascular root surface area as a prognostic identification criterion for gingival recessions and to compare the predictive value of the Miller classification and avascular root surface area (AERSA) calculation on the final root coverage outcomes.

Enrollment: 91 patients

Trial design

91 participants in 3 patient groups

AERSA-I gingival recession

Description:

The AERSA classification was developed based on 15 mm2 which is the lowest cut-off point and the group of AERSA ≤ 15 mm2 named as AERSA-I (low risk group)

AERSA-II gingival recession

Description:

AERSA \> 15 mm2 named as AERSA-II (high risk group).

Miller gingival recession

Description:

Gingival recessions classified according to Miller
