Filter by:The primary purpose of this protocol is to isolate, investigate and compare the regenerative and differentiation potential of mesenchymal stem cells (MSC's) in the gingival (gum) tissue harvested from two different locations from the roof of the mouth (palate), that is from the front part(premolar)and back part(molar). MSC's are known for their capacity to form different kinds of hard and soft tissue including bone, fibers for periodontal ligaments, cementum and dentin, thus this study can help in optimizing their clinical application and transplantation approaches in tissue regeneration.
This study will compare two incision designs to allow for coronal gingival/mucosal flap advancement and tissue augmentation with acellular dermal matrix (ADM) graft around teeth with gingival recession and a lack of adequate keratinized gingiva. To the investigators knowledge, these two techniques have not been compared for differences in clinical (amount of root coverage, tissue thickness, and esthetics) and patient-centered outcomes (pain, swelling, change in daily activities) in a controlled study.
A single center, prospective clinical trial is planned to investigate the effect of different emergence angles of implant restorations on peri-implant soft tissue recession and implant marginal bone loss. The primary outcome is to systematically evaluate the association of implant-, peri-implant tissue-, and restoration-related factors with facial mucosal level changes.
This randomized controlled single blinded parallel clinical trial is held to monitor if the use of the non pedicled buccal fat pad graft will result in post operative pain as a primary outcome compared to that occurs with the use of the sub epithelial connective tissue graft in treating Miller Class I and Class II gingival recession
Cigarette smoking is a patient-related factor that can affect healing of periodontal tissues and the success rate of root-coverage procedures. Neither the nature nor the mechanisms of action of cigarette smoking on root coverage are fully understood. Therefore, the hypothesis that cigarette smoking has negative impacts on the outcomes of root coverage after CAF surgery in systemically healthy individuals with an initial gingival thickness of at least 0.8 mm and who practice optimal oral hygiene was tested. It was also hypothesized that baseline analysis of disease-related biomarkers would shed light on the underlying mechanisms of a possible effect.
There are some orthodontics treatments that perform risk movements ,and a bone dehiscence may be expected. In that cases mucogingival surgery , such as connective tissue grafts, is necessary prior to tooth movement. The connective tissue graft in combination with coronal advanced flap is still considered the gold standard , although the use of porcine collagen matrix has obtained promising results for treatment of Miller class I and II recession defects. Most of the studies report clinical results after a connective tissue graft and there is no evidence about the type of attachment obtained after the graft is performed, a few articles have shown histological results. But, as a rule , a histological study is only performed under exceptional circumstances such as a dental fracture, untreatable decay, tooth extraction for orthodontic reasons, or other reasons. Most of the techniques results in the formation of a long junctional epithelium and connective tissue attachment with fibers parallel to the root surface. Animals studies have shown a shorter epithelium and a larger new cementum formation after the use of the collagen matrix.
The purpose of this prospective, double-blinded, randomized, split-mouth study is to compare the effectiveness of a porcine collagen matrix (CM) and coronally advanced flap (CAF) with or without the addition of enamel matrix derivative (EMD) in the treatment of Miller Class I, II, or predictable class III recession defects. One defect will receive CM + CAF + EMD (Experimental), while the other will receive CM + CAF (Control) alone. The treatment of 60 similarly sized Miller class I, II, or predictable class III recession defects on single-rooted teeth in 30 subjects using CM + CAF + EMD or CM + CAF alone will be evaluated. The subjects will be in good health, non-smokers, periodontally healthy with good oral hygiene and have no contraindications to periodontal surgery. Paired, similar sized defects on single-rooted teeth will be in the same subject and measure within 2mm of each other. One defect will be randomly assigned as the test group using CM + CAF + EMD, and the other as the control group using only CM + CAF. Clinical measurements will be made using a UNC-15 periodontal probe by calibrated, board certified periodontists and will include: probing depth (PD), clinical attachment level (CAL), vertical recession (RD), and width of keratinized tissue (KT). Percent root coverage (%RC) will be calculated. The measurements will be used to evaluate surgical outcome. Surgical outcome will also be assessed using stone models. All measurements will be taken at baseline (on the day of the surgery) and 3 and 6 months post-surgery for comparison.
The aim of this study was to evaluate the effect of two different treatment agents used in conjunction with subepithelial connective graft technique on root coverage outcomes in multiple recession defects. Half of patients will receive root treatment with antimicrobial photodynamic therapy and the other half will receive photobiomodulation therapy by laser on surgery site.
Aesthetics for individuals become increasingly important, while the aesthetic effects of periodontal disease is an important issue that should be assessed by the patient's perception. The results demonstrate that the periodontal aesthetic perception scale showed reliable and valid scores in healthy controls and periodontal patients. The periodontal aesthetic perception scale may be an appropriate tool to assess periodontal esthetic in clinical and research settings.
The present placebo-controlled parallel design clinical study was planned to determine the effect of low level laser therapy on clinical periodontal conditions and dimensions of free gingival graft as well as postoperative pain levels in the surgical area.
