Filter by:Gingival recession is a clinical problem that increases with age and affects patient comfort. It is defined as the displacement of the gingival margin to a more apical position of the cementum-enamel border of the tooth. Coronally advanced flap (CAF) or tunnel technique (TUN) with subepithelial connective tissue procedures have been reported to be the most predictable methods of single gingival recession treatments. The ultimate goal of these plastic periodontal surgical procedures is to close the exposed root surface and achieve optimum aesthetic results. The main indications for root coverage (RC) procedures are aesthetic concern, root hypersensitivity, prevention of cervical abrasion and root caries, improvement of restorative results, and facilitation of plaque control. The use of a subepithelial connective tissue graft (SCGT) combined with a coronally positioned flap is considered the gold standard by many authors for single gingival recession treatments. De-epithelialization of free gingival grafts (DGG) has been proposed, especially when palatal tissue thickness is insufficient (≤2.5 mm) and larger graft size in the apico-coronal or mesio-distal directions is required. In this technique, the graft of the required width and length is separated from the lateral side of the palate, and then the 0.3-0.5 mm thick epithelial layer of the resulting graft is cut from the connective tissue layer. Ultrasonography (USG) is based on the principle of recording data obtained as a result of ultrasound waves sent with the help of a probe hitting and reflecting on substances of different densities. This technique is widely used in medical practice. In dentistry, the USG method is used to measure the alveolar bone level and the dimensions of the periodontium to evaluate the gingival thickness. It also has functions to evaluate color power and color speed, as well as blood flow. The study hypothesizes that combining SCGT and DGG with a coronally positioned flap could yield different clinical outcomes in patients with a single buccal gingival recession. This study aims to compare the clinical success of connective tissue grafts obtained by two different surgical methods in covering the root surface with ultrasonography (USG).
Patients were randomly distributed into two groups (G1 and G2), all patients were treated by a submerged dental implant protocol and free gingival graft (FGG) harvested from the palate as follows: - Group 1 (G1), received the FGG two months before implant placement. - Group 2 (G2), received the FGG at the time of second-stage surgery (i.e. at the time of healing abutment placement). All periodontal and radiographic assessments were done by the same operator who was neither involved in the evaluation nor the distribution process. The operator did all the evaluation steps and was completely blinded to the treatment protocol.
The aim of this study is to investigate the effects of conventional suture (CS) and modified sling suture (MSS) techniques, applied in free gingival graft (FGG) surgery using gingival unit graft (GUG) and conventional graft (CG) techniques, on clinical parameters and graft dimensions.
Palatal-tissue harvesting is a routinely performed procedure in periodontal plastic surgery. Subepithelial connective tissue graft (sCTG) is considered the gold standard in root coverage. However, over the years, several materials have been attempted to accelerate wound healing and to decrease the post-operative patient discomfort and pain, which are considered the most common disadvantages of tissue harvesting from the palate. Reharvesting from the same region could be necessary in some complicated gingical recessions. For this reason, patients may face long treatment times due to recovery periods of the palate between surgeries. Platelet-rich fibrin (PRF) which has 3-dimensional fibrin matrix structure contributes to regeneration of surgical wounds by releasing growth factors for 10-14 days and showing angiogenic properties. In medicine and dentistry, ultrasonography (USG) method can be used to measure tissue thickness, vascularization, elasticity and blood flow. USG, as a non-invasive method, can provide objective data in evaluating the effects of surgical techniques and biomaterials used on soft tissue healing dynamics and tissue perfusion. The investigators hypothesised that leukocyte rich PRF (L-PRF) application to the palatal area after sCTG harvesting could increase palatal tissue thickness and vascularity throughout 3-month follow-up period compared to the controls. Therefore, in this study, the investigators aimed to evaluate the effects of the L-PRF membrane on soft tissue donor site healing after harvesting sCTG in terms of wound healing dynamics using USG method.
The goal of this observational prospective study is to objectively assess the dimensional (volume & linear variance) and clinical changes of vestibular gingival soft tissues upon treatment with laser-aided pouch roll augmentation technique and implant placement over a 12-month follow-up. Twelve patients with 16 mild horizontal ridge deficiencies in different edentulous sites scheduled for implant placement were enrolled. Digital impressions were taken with an intra-oral laser scanner and software and analyzed before (day 0) and 12 months after laser-aided pouch roll augmentation surgery. The digital files were converted to STL format and superimposed to assess peri-implant volumetric and linear dimensional variations in selected regions of interest (ROI) by a 3D analysis software. Operator-assessed clinical periodontal parameters (probing depth PD, bleeding on probing BoP, plaque index PI) were recorded. Patient-reported outcome (pain, discomfort, treatment liking) and aesthetic result were evaluated by administration of appropriate questionnaires.
The aim of the present study was to compare between nanocrystalline hydroxyapatite and tricalcium phosphate carried on PRP membrane in treatment of Miller's class 1 gingival recession in human.
The primary objective of this study was to evaluate time effect on the clinical predictability of collagen matrix Xenograft (CMX) with melatonin gel versus connective tissue graft (CTG) and determine whether it is proposed to be an alternative in multiple adjacent gingival recession (MAGR) in recession type one (RT1)
The aim of this study was to examine the effects of Botulinum Toxin-A (BTX-A) injection to the mental muscle on the free gingival graft (FGG) operation. Forty patients with Miller class III gingival recession and keratinized gingival insufficiency in their lower 1st incisors were divided into 2 groups as FGG operation (n=20) and 5 unit (U) BTX-A injection into the mental muscle immediately after FGG operation (n=20). Periodontal parameters (plaque index (PI), gingival index (GI), probing pocket depth (PPD), keratinized gingival amount (KGA), attached gingival amount (AGA)) were measured from the lower 1st incisors at the beginning and at the 1st, 3rd and 6th months after the operation, clinical attachment level (CAL), gingival thickness (GT), gingival recession amount (GRA), gingival recession width (GRW) and root closure percentage (RCP (%)) were evaluated. There was no statistically significant difference in terms of PI and GI levels (p>0.05). The PPD levels of the study group at the postoperative 3rd month was found to be statistically significantly lower than the control group (p<0.05). While the change in GT and RCP (%) levels were found to be statistically significantly higher than the control group, the change in GRW and CAL levels were statistically significantly lower (p<0.05). According to the results of this study, it can be stated that BTX-A injection applied to the mental muscle after FGG operation may have positive effects in terms of KGA, AGA, GT, RCP (%), GRW and CAL parameters.
The purpose of this study was to develop a periodontal disease prediction software and a patient-based gingival recession simulator for clinical practice aiming at improving oral hygiene motivation of patients with periodontal problems.
The clinical trial studies patients with gingival recession defects (receding gums). The goal of the study is to test whether the additional use of enamel matrix derivatives (EMD), combined with the use of a coronally advance flap (CAF) and a CM (collagen matrix), shows a better outcome compared to a comparison group. The comparison group comprises patients receiving treatment with CAF and CM without the use of EMD.
