Objectives:
The treatment of gingival recessions (GRs) is operator-sensitive and dependent upon several local anatomical factors. The aim of this study was to introduce a difficulty score for the treatment of localized GRs with the coronally advanced flap (CAF) and to test its consistency among different operators.
Materials And Methods:
A rubric (difficulty score) consisting of the assessment and grading of 8 anatomical parameters (anatomical papilla, apical and lateral keratinized tissue width, apical and lateral frenum, vestibulum depth, scar tissue, and mucosal invagination) is described based on the available evidence and the authors' experience. Inter-examiner agreement, with the score, was tested on 32 localized GRs among four different experienced practitioners.
Results:
Minor discrepancies were observed in the total scores between the reviewers (intraclass correlation coefficient [ICC] 0.95). A good reproducibility, with ICCs ranging from 0.56 to 0.98, was found for the individual parameters. All models showed high absolute variance contribution conveying true differences among the cases, and small examiner variance, demonstrating minor systematic variability among the four reviewers and reproducible evaluations.
Conclusions:
The proposed difficulty score for the treatment of GRs with CAF was reproducible among different operators. Clinical interventional studies are the next step to validate the clinical magnitude of the present score.
Clinical Relevance:
A novel tool for evaluating the difficulty of the treatment of isolated gingival recession using CAF was described. Clinicians can benefit from this score when assessing the expected level of complexity of the surgical case.
