  • clinical and anatomical factors limiting treatment outcomes of gingival recession a new method to predetermine the line of root coverage
    Journal of Periodontology, 2006
    Co-Authors: Giovanni Zucchelli, Tiziano Testori, M De Sanctis
    Abstract:

    Complete root coverage is not always achievable, even in gingival recession with no loss of interproximal attachment and bone. The cemento-enamel junction is the most widely used referring parameter to evaluate root coverage results. The aim of the present study was to describe the most frequent diagnostic mistakes that may lead to incomplete root coverage in Miller Class I and II gingival recessions and to suggest a method to predetermine the level/line of root coverage in non-molar teeth. The line of root coverage (i.e., the level/line to which the soft tissue margin will be positioned after the healing process of a root coverage surgical technique) was predetermined by calculating the ideal vertical dimension of the Interdental Papilla of the tooth with the recession defect. This method was applied to 120 recession-type defects affecting non-molar teeth of 80 young healthy subjects that were treated with root coverage surgical procedures over the last 5 years. All recessions were Miller Class I or II and were associated with at least one of the following characteristics: 1) traumatic loss of the tip of the Interdental Papilla(e); 2) tooth rotation; 3) tooth extrusion with or without occlusal abrasion; and 4) a cervical abrasion defect with no evidence of the cemento-enamel junction. The line of root coverage may be considered the clinical cemento-enamel junction because it may substitute the anatomic cemento-enamel junction when this is no longer clinically visible on the tooth with recession or when the ideal conditions to obtain complete root coverage are not fully represented.

  • the connective tissue graft wall technique and enamel matrix derivative to improve root coverage and clinical attachment levels in miller class iv gingival recession
    International Journal of Periodontics & Restorative Dentistry, 2014
    Co-Authors: Giovanni Zucchelli, Claudio Mazzotti, Federico Tirone, Monica Mele, Pietro Bellone, Ilham Mounssif
    Abstract:

    : The case reports in this article describe a surgical approach for improving root coverage and clinical attachment levels in Miller Class IV gingival recessions. Two gingival recessions affecting maxillary and mandibular lateral incisors associated with severe Interdental hard and soft tissue loss were treated. The surgical technique consisted of a connective tissue graft (CTG) that was placed below a coronally advanced envelope flap and acted as a buccal soft tissue wall of the bony defect treated with enamel matrix derivative (EMD). No palatal/lingual flap was elevated. In the first clinical case, 6 months after surgery a ceramic veneer was placed to correct tooth extrusion and improve the overall esthetic appearance. One year after the surgery in both cases, clinically significant root coverage, increase in buccal keratinized tissue height and thickness, improvement in the position of the Interdental Papilla, and clinical attachment level gain were achieved. The radiographs demonstrate bone fill of the intrabony components of the defects. This report encourages a novel application of CTG plus EMD to improve both root coverage and regenerative parameters in Miller Class IV gingival recessions.

  • effect of hyaluronic acid filler injection on the Interdental Papilla in a mouse model of open gingival embrasure
    International Journal of Environmental Research and Public Health, 2020
    Co-Authors: Soobin Kim, Jae Hyun Park, Jaehun Cho, Seongsuk Jue, Jiyoun Kim
    Abstract:

    The black triangle resulting from Interdental Papilla (IDP) loss is associated with poor aesthetics and difficulty in pronunciation and food impaction. There is limited knowledge of gingival tissue inflammatory response to hyaluronic acid (HA) filler injection, a minimally invasive IDP reconstruction method. This study aimed to examine the morphological and histological changes in IDP and the inflammatory cytokine localization to the IDP post-HA filler injection using an open gingival embrasure (OGE) mouse model. Mice from the control, sham, and OGE groups were attached with reference, inactive, and activated wires for 5 days, respectively. The degree of IDP loss was determined based on the spring-Papilla distance (SPD). Morphological and histological changes in the OGE group injected with phosphate-buffered saline (PBS) or HA fillers were examined on days 2 and 7 post-injection. Immunohistochemical analysis was performed to determine the localization patterns of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, myeloperoxidase (MPO), and Ki67. Five days post-wire attachment, the control and OGE groups exhibited a significantly higher SPD than the sham group (p < 0.0167). The SPD of the HA filler injection group was significantly lower than that of the PBS injection group on days 2, 4, and 7 post-injection (p < 0.05). The IDP of the OGE group was wide and flat. HA filler was stable in the connective tissue underlying the epithelial tissue even on day 7 post-injection. TNF-α, IL-1β, IL-6, MPO, and Ki67 were highly localized to the connective tissue surrounding the filler on day 2, which decreased on day 7 post-injection. Thus, HA filler can safely and successfully reconstruct the IDP in cases of OGE.

  • esthetic considerations in Interdental Papilla remediation and regeneration
    Journal of Esthetic and Restorative Dentistry, 2010
    Co-Authors: Anita Angela Sharma, Jae Hyun Park
    Abstract:

    This article reviews the etiology and treatment of open gingival embrasures or black triangles. An open gingival embrasure or black triangle occurs as a result of a deficiency of Papilla beneath the contact point. The treatment of open embrasures may require restorative, orthodontic and periodontal considerations depending on the underlying etiology. The authors reviewed a total of 42 articles including review of literature, radiographic, cross-sectional, and retrospective studies in Ovid search engine using the terms "open gingival embrasure,""Interdental Papilla," and "black triangle." The studies provided information regarding etiology, diagnosis, and treatment of open embrasures. There are several risk factors leading to the development of open gingival embrasures. These factors include aging, periodontal disease, loss of height of the alveolar bone relative to the interproximal contact, length of embrasure area, root angulations, interproximal contact position, and triangular-shaped crowns. Treatment of open embrasures requires an interdisciplinary approach of orthodontic, periodontic, and restorative treatment. CLINICAL SIGNIFICANCE Open gingival embrasures are complex esthetic and functional problems. An interdisciplinary team approach with the general dentist, orthodontist, and periodontist is critical. Management of open embrasures requires careful evaluation of the underlying etiology.

  • coronally advanced flap procedure is the Interdental Papilla a prognostic factor for root coverage
    Journal of Periodontology, 2001
    Co-Authors: Daniele Saletta, Giovanpaolo Pini Prato, Umberto Pagliaro, Carlo Baldi, Mauro Mauri, Michele Nieri
    Abstract:

    Background: This study was designed to verify if the dimension of the Interdental Papilla may be a prognostic factor for the clinical outcome of the coronally advanced flap (CAF) in the treatment of gingival recessions. Methods: Thirty-three Miller Class I recessions were treated in 33 patients using the CAF procedure. Two types of measurements were performed: 1) clinical measurements (probing depth, recession depth, width of keratinized tissue, clinical attachment level) were recorded at baseline and 3 months after surgery and 2) all recessions were photographed and transformed into computer images. A specific software allowed recording of both linear and square measurements. The following digital measurements were recorded at baseline: 1) base, height, and area of the mesial and distal Papillae adjacent to the involved tooth and 2) width/depth of the recession and the area of the exposed root surface of the involved tooth. The residual recession area, if any, was recorded 3 months after surgery. The dig...

  • surgical reconstruction of Interdental Papilla using an interposed subepithelial connective tissue graft a case report
    Journal of Prosthetic Dentistry, 2004
    Co-Authors: Joao Carnio
    Abstract:

    Abstract The unpredictability of current surgical procedures for Papilla reconstruction has been a matter of concern for both periodontists and patients. This case report presents a complete Papilla reconstruction in a 20-year-old woman using an interposed subepithelial connective tissue graft. The results show that this technique can be successfully used in treating the loss of Papillae and achieving long-term stability. The objective of this report is to describe the surgical technique and comment on the factors that may have influenced the final result.— Reprinted with permission of Quintessence Publishing.
