The influence of interradicular anatomy on the predictability of periodontal regenerative therapy of furcation defects: a retrospective, multicenter clinical study.

Background: The relationship between the anatomy of the interradicular space and success in regenerative therapy of furcation defects is discussed in this paper. The goal of this retrospective, multicenter clinical study is to clinically evaluate the relationship between the interradicular conformation and regenerative therapy success with the use of a novel measurement method.

Methods: One hundred thirty-eight radiographs of mandibular molars with furcation defects that had been treated with regenerative therapy were collected from six clinical centers.

Radiographic ratios for classifying furcation anatomy: proposal of a new evaluation method and an intra-rater and inter-rater operator reliability study.

Objectives: Even if it seems to be an important anatomical parameter for tissue regeneration, few studies in literature evaluate the "mean measure" of root divergence. Most of them are linear measurements, which hardly describe the dental furcation conformation in its entirety. It is left to the subjectivity of the operator deciding whether a furcation is convergent or divergent.

Regenerative Surgery of Mandibular Class II Furcation Defects: A Comparison of Two Techniques in a Randomized Clinical Trial with 3D CBCT Measurements at 24 Months.

The aim of the present study was to evaluate, clinically and via CBCT, the long-term efficacy of a bioresorbable polylactic acid membrane combined with deproteinized bovine bone graft (DBBM) and compare it to enamel matrix derivative (EMD) combined with DBBM graft in the treatment of class II furcation defects. Sites were randomly assigned to the test group (Guidor Matrix Barrier + Bio-Oss) or the control group (Emdogain + Bio-Oss). Probing pocket depth (PPD), clinical attachment level (CAL), gingival recession (REC), and keratinized tissue (KT) width were assessed at 12 and 24 months, and radiographic bone gain was investigated at 24 months via CBCT.

Management of Furcation-Involved Molars: Recommendation for Treatment and Regeneration.

Furcation involvement (FI) is one of the most detrimental factors affecting tooth survival rate over time. Several authors have used the severity of FI for assessing the prognosis of the tooth and the complexity of periodontal disease. While many approaches have been shown to improve the prognosis of furcation-involved teeth, clinical guidelines recommending one treatment or another (based on the horizontal and vertical component of the furcation defects) have not yet been proposed.

The Influence of Gingival Phenotype on the Outcomes of Coronally Advanced Flap: A Prospective Multicenter Study.

The goal of this study was to evaluate the influence of gingival phenotype (GPh) on the clinical outcomes of coronally advanced flap (CAF). In this prospective study, 24 gingival recessions (recession type RT1 class or Miller Classes I and II) in 21 patients were treated with CAF alone. Patients were classified as having thin, medium, thick, or very thick GPh using a color-coded probe.

Graftless Tunnel Technique for the Treatment of Multiple Gingival Recessions in Sites with Thick or Very Thick Biotype: A Prospective Case Series.

Tunnel (TUN) technique is normally performed in combination with soft tissue grafts, either autogenous connective tissue graft (CTG) or substitutes, regardless of a patient's biotype. The aim of this study was to investigate the efficacy of graftless TUN in the treatment of multiple gingival recessions (GRs) characterized by thick or very thick biotype. Twenty-seven GRs were treated in seven patients using graftless TUN.

Gingival Margin Stability After Mucogingival Plastic Surgery. The Effect of Manual Versus Powered Toothbrushing: A Randomized Clinical Trial.

Background: Oscillating-rotating power toothbrushes have been proven to be clinically efficacious. To the best of the authors' knowledge, a clinical evaluation of the safety of these toothbrushes after surgical root coverage procedures has not been published. The aim of this study is to evaluate the gingival margin (GM) stability with the use of an oscillating-rotating toothbrush compared with a manual toothbrush.

Decision Making in Gingival Recession Treatment: Scientific Evidence and Clinical Experience.

Focused Clinical Question: What are the key considerations for selecting the best surgical approach in mucogingival plastic surgery? Summary: Treatment of gingival recession has become an important therapeutic issue due to the increasing number of cosmetic requests from patients. The dual goals of mucogingival treatment include complete root coverage, up to the cemento-enamel junction, and blending of tissue color between the treated area and non-treated adjacent tissues. Even though the connective tissue graft is commonly considered the "gold standard" for treatment of recession defects, it may not always be the best surgical option for every case.
