    Aesthetic perception after root coverage procedure

    JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 8 2008
    Roberto Rotundo
    Abstract Aim: To investigate the aesthetic perception of the clinical outcomes of a simulated root coverage procedure in three different groups: patients, dentists, and periodontists. Material and Methods: 100 patients, 107 general dentists affiliated with the Dental Association of Prato, Italy, and 81 active members of the Italian Society of Periodontology were recruited for this study. The following variables: age, gender, level of education, place of residence, and years of practice (only for dentists and periodontists) were recorded by means of a questionnaire administered to each subject within the three different groups. In addition, the participants in the study were requested to assign scores to images of eight simulated clinical cases of gingival recessions: a pre- and post-treatment image for each case. Results: Statistically significant differences between groups were not detected in most of the scores. Gender and residence were not significantly associated with the scores, while age was correlated for two clinical cases (p=0.0014 and 0.0017). All the cases of complete root coverage showed the highest scores among all the participants. Conclusions: These results showed that complete root coverage following root coverage procedure is perceived as the most successful outcome by patients, dentists, and periodontists. [source]

    Gingival Zenith Positions and Levels of the Maxillary Anterior Dentition

    JOURNAL OF ESTHETIC AND RESTORATIVE DENTISTRY, Issue 2 2009
    STEPHEN J. CHU DMD
    ABSTRACT Purpose:, The location of the gingival zenith in a medial-lateral position relative to the vertical tooth axis of the maxillary anterior teeth remains to be clearly defined. In addition, the apex of the free gingival margin of the lateral incisor teeth relative to the gingival zeniths of the adjacent proximal teeth remains undetermined. Therefore, this investigation evaluated two clinical parameters: (1) the gingival zenith position (GZP) from the vertical bisected midline (VBM) along the long axis of each individual maxillary anterior tooth; and (2) the gingival zenith level (GZL) of the lateral incisors in an apical-coronal direction relative to the gingival line joining the tangents of the GZP of the adjacent central incisor and canine teeth under healthy conditions. Materials and Methods:, A total of 240 sites in 20 healthy patients (13 females, 7 males) with an average age of 27.7 years were evaluated. The inclusion patient criteria were absence of periodontal disease, gingival recession, or gingival hypertrophy as well as teeth without loss of interdental papillae, spacing, crowding, existing restorations, and incisal attrition. GZP dimensions were measured with calibrated digital calipers for each individual tooth and within each tooth group in a medial-lateral direction from the VBM. GZLs were measured in an apical-coronal direction from a tangent line drawn on the diagnostic casts from the GZPs of the adjacent teeth. Results:, This study demonstrated that all central incisors displayed a distal GZP from the VBM, with a mean average of 1 mm. Lateral incisors showed a deviation of the gingival zenith by a mean of 0.4 mm. In 97.5% of the canine population, the GZP was centralized along the long axis of the canine. The mean distance of the contour of the gingival margin in an apical-coronal direction of the lateral incisors (GZL) relative to gingival line joining the tangent of the adjacent central and canine GZPs was approximately 1 mm. Conclusion:, This investigation revealed a GZP mean value of 1 mm distal from the VBM for the central incisor tooth group. The lateral incisors showed a mean average of 0.4 mm. Thecanine tooth group demonstrated almost no deviations of the GZP from the VBM. The GZL of the lateral incisors relative to the adjacent central incisor and canine teeth were more coronal by approximately 1 mm. These data could be used as reference points during esthetic anterior oral rehabilitation. CLINICAL SIGNIFICANCE The information presented in this article can be clinically applied to reestablish the proper intratooth GZPs of the maxillary anterior teeth during periodontal crown lengthening or root coverage procedures. In addition, the intra-arch gingival level of the lateral incisor gingival zenith relative to the adjacent central and canine teeth can be appropriately established. [source]

    Acellular dermal allograft for vestibuloplasty,an alternative to autogenous soft tissue grafts in preprosthetic surgical procedures: A clinical report

    JOURNAL OF PROSTHODONTICS, Issue 2 2003
    Monish Bhola DDS
    Various vestibular extension procedures have been described in the literature over the past 6 decades, including the use of free gingival grafts. An acellular dermal allograft has been used as a substitute for autogenous soft tissue grafts in root coverage procedures. This clinical report describes the use of such an allograft as a substitute for palatal donor tissue in the vestibular extension of an edentulous maxillary arch with multiple frenum attachments before fabrication of a complete denture. In this patient, healing was uneventful, and 6-month clinical observations demonstrated an apical positioning of the mucogingival junction with an increase in vestibular depth, and the absence of multiple frenae. The acellular dermal allograft appears to be a useful substitute for autogenous palatal grafts in preprosthetic surgery. This approach has many advantages over the free gingival graft, including no donor site morbidity, unlimited availability, and better color match. [source]
