(14) Clinical results of root coverage
are generally evaluated according to the root coverage
percentage and sometimes the complete root coverage
To improve the results, various regenerative procedures have been tried with CAF which enhances root coverage
. One of such material is platelet-rich fibrin (PRF) which is a second-generation autologous platelet concentrate and does not require any extensive preparation as in need in the preparation of platelet-rich plasma (PRP).
esthetic score after treatment of gingival recession: an interrater agreement multicenter study.
Patient was followed up for 9 months and 100% of root coverage
was observed (Figure 9).
One recent review of the literature  reported, for cases treated with CAF, only a mean root coverage
ranging from 34.0% to 86.7% and a percentage of recessions that resulted complete coverage ranging from 11.0% to 60.0%.
For example, Miller reported (100)% correlation between heavy smoking and failure to achieve complete root coverage
using free gingival grafts.
Then they explain diagnosis and treatment from such perspectives as morphological characteristics of NCCLs, clinical analysis and diagnosis of cervical dentin hypersensitivity and NCCLs, and surgical protocols: periodontal therapy and root coverage

These considerations led to the development of a minimally invasive flap design for root coverage
surgery, namely, the tunnel technique [4, 5].
Objective: To evaluate whether microsurgery gains better result in root coverage
compared to conventional surgical techniques.
The pedicle graft was introduced in 1956 by Grupe and warren3 for root coverage
as a laterally repositioned full thickness flap.
The shorter bristles give really good root coverage
, the long ones on the arch are good for enlongating the outer corner.
