Cairo F, Nieri M, Cincinelli S, Mervelt J, Pagliaro U. The interproximal clinical attachment level to classify gingival recessions and predict root coverage outcomes: an explorative and reliability study. J Clin Periodontol 2011; doi: 10.1111/j.1600‐051X.2011.01732.x.

Background: The aims of this study were (i) to test the reliability of a new classification system of gingival recessions using the level of interproximal clinical attachment as an identification criterion and (ii) to explore the predictive value of the resulting classification system on the final root coverage outcomes.

Material and methods: Patients showing at least one buccal gingival recession were recruited by one operator. Three recession types (RT) were identified. While class RT1 included gingival recession with no loss of interproximal attachment, class RT2 recession was associated with interproximal attachment loss less than or equal to the …
