After a description of advantages and disadvantages of traditional surgical techniques for the correction of gingival retractions, a new surgical techniques is indicated: the subepithelial connective tissue graft. The latter technique is assessed and described in detail and its relative efficacy in comparison with the traditional techniques is emphasized.

[Relations of gingival hypertrophy and blood levels of cyclosporin A in patients with renal transplants].

Gingival overgrowth is defined as hyperplasia of gingival tissue due to local, systemic or drug-related causes. To see if the incidence and severity of this side-effect are related to cyclosporine A (CyA) dosage and/or blood levels BCyA), we analysed data from 24 renal transplanted outpatients, grouped as follows: controls (C, n = 3): patients on immunosuppressive therapy other than CyA; group 1 (G1, n = 10): patients with BCyA steadily 300 ng/mL (RIA); group 2 (G2, n = 11): patients with BCyA steadily between 301 and 650 ng/mL. BCyA averaged 290 +/- 21 in G1 and 481 +/- 100 in G2 (p less than 0.001): mean cyclosporine A dosage (mg/kg/die) was not significantly different: 4.1 +/- 1.4 in G1 and 4.97 +/- 2.4 in G2. However, six patients in G2 also received calcium antagonists known to increase CyA blood levels (diltiazem and nicardipine) for clinical purposes or deliberately to increase CyA bioavailability. Mean time from transplant was (in months) 19 +/- 11 in G1, 16 +/- 15 in G2 and 62 +/- 24 in C (G1 vs G2: NS; C vs G1 and 2: p less than 0.001). Mean GFR (mL/min) was 75 +/- 22 in C, 65 +/- 18 in G1 and 53 +/- 19 in G2 (NS). Dental hygiene, as assessed by scoring (0-3: absent, mild, moderate and severe) the bacterial plaque, was similar in all groups. Gingival overgrowth, was similarly scored (0-3) and was absent in C and in 20% of G1, mild in 40% of G1 and 33% of G2, moderate in 40% of G1 and 33% of G2 and severe in 0% of G1 and 33% of G2 (G1 vs G2: p less than 0.05). Our data suggest that the severity of gingival overgrowth in transplanted patients with similar oral hygiene is mainly related to CyA blood levels.

[Lateral sliding flaps in mucogingival surgery].

Reference is made to parodontal surgery techniques employing lateral sliding flaps mucogingival for the treatment of gingival schisis. Grupe & Warren (1965) proposed the use of a flap from the parts contiguous to that affected by the schisis. The technique was then developed by the introduction of bipapillar flaps and a flap taken from a toothless saddle. All operations using sliding flaps form part of the most difficult area in mucogingival surgery, due to difficulty of securing the "taking" of the flap on the root cement of the parts affected by schisis.

[Free gingival graft in mucogingival surgery].

Palatine grafts, which today represent the simplest and most reliable technique for enhancing the adherent gum--a problem of great importance in periodontal treatment--are discussed together with other techniques designed for the same purpose. Bone site palatine grafts which restore adherent gum on the alveolar bone, are distinguished from osteo-dental site grafts which are proposed for the treatment of split gums and which only take partially on the radicular surface.
