Application of enamel matrix derivative in conjunction with non‐surgical therapy for treatment of moderate to severe periodontitis: A 12‐month, rando…
2020
BACKGROUND Treatment of periodontitis aims to halt progressive bone and attachment loss and regenerate periodontal structures. In this study, the effect of using an enamel matrix derivative (EMD) as an adjunct to non-surgical periodontal therapy (test) versus non-surgical therapy alone (control) was evaluated. METHODS A prospective, split-mouth, multicenter study evaluated scaling and root planing (SRP) with and without EMD in 51 patients presenting with moderate to severe periodontitis (PPD = 5 to 8 mm) in at least 2 pockets per contralateral quadrants within the same arch. The primary outcome variable was change in clinical attachment level (CAL) after 12 months. Secondary variables inclu…
Recession Coverage Using Soft Tissue Substitutes
2018
Today, a variety of surgical procedures can be used to successfully treat gingival recession defects. Among them, the autogenous connective tissue graft in conjunction with a coronally advanced flap is commonly considered the gold standard procedure. However, the most significant disadvantages of this procedure are the potential morbidity associated with autogenous tissue harvesting and the limited availability of donor tissue. For these reasons, alternative surgical procedures using membranes, enamel matrix derivative, and soft tissue graft substitutes have been proposed and tested. The aim of the present chapter is to provide an overview on the use of soft tissue substitutes as a possible…
Herpes Simplex I virus impairs regenerative outcomes of periodontal regenerative therapy in intrabony defects: a pilot study.
2011
Aim To evaluate the impact of herpesvirus type-1 and -2 on the clinical outcomes of periodontal regenerative procedures in isolated deep intrabony pockets, in an experimental population with no detectable periodontal pathogens. Materials and Methods Seventeen periodontal intraosseous defects in 17 moderate-to-advanced periodontitis patients were treated with regenerative therapy and amelogenins. Microbiological evaluation was performed at baseline (after the completion of initial therapy) and at 1 year to exclude the presence of periodontal pathogens. Herpesviruses-1 and -2 DNA were quantified in the pocket tissues associated to the intrabony defect using molecular assays. Clinical attachme…
Flapless application of enamel matrix derivative in periodontal retreatment: A multicentre randomized feasibility trial
2021
AIM To investigate the potential benefit of enamel matrix derivative (EMD) as adjunct to re-instrumentation of residual pockets persisting after steps 1 and 2 of periodontal therapy. MATERIAL AND METHODS 44 adult patients participated in a multicentre feasibility randomized clinical trial with split-mouth design. They had presented at re-evaluation after initial non-surgical periodontal therapy (steps 1 and 2 of periodontal therapy) for generalized periodontitis with at least 2 teeth with residual probing pocket depths (PPD) ≥5 and ≤8 mm, with bleeding on probing (BOP). Two teeth with similar PPD were randomized to receive re-instrumentation either with (test) or without (control) adjunctiv…
Subepithelial connective tissue graft with or without enamel matrix derivative for the treatment of Miller class I and II gingival recessions: a cont…
2012
Background The aim of this study was to evaluate whether the combination of enamel matrix derivative (EMD) with subepithelial connective tissue graft (SCTG) plus coronally advanced flap (CAF) would improve the treatment outcomes of Miller class I and II gingival recessions when compared with the same technique (SCTG plus CAF) alone. Methods The study was designed as a randomized, parallel, controlled, double-blinded clinical trial. Forty-two patients were randomly assigned in the test group (SCTG plus EMD) and in the control group (SCTG). Patients had at least one gingival recession ≥ 2 mm. The clinical parameters were evaluated at baseline and at 14 d, 1, 3, 6 and 12 mo follow-up time poin…
Influence of different biomaterials on the viability of Aggregatibacter actinomycetemcomitans
2011
Abstract Objectives The aim of the present in vitro study was to evaluate the effects of different biomaterials used for regenerative periodontal surgery on the growth of the periodontopathogen Aggregatibacter actinomycetemcomitans . Methods Three commercially available biomaterials of synthetic origin (hydroxyapatite/beta-tricalcium phosphate, nanostructured hydroxyapatite paste, oily calcium hydroxide suspension), a bovine-derived xenograft as well as an enamel matrix derivative (EMD) were added in different concentrations to calibrated suspensions of A. actinomycetemcomitans ATCC 43718/33384 (serotype b/c). Equal aliquots (0.1 ml) for the viability assay were taken after 5 min, 1 h, 3 h,…
Early root surface colonization by human periodontal ligament fibroblasts following treatment with different biomaterials
2013
The present in-vitro study examined the effects of different biomaterials on early root surface colonization by human periodontal ligament (PDL) fibroblasts using confocal-laser-scanning-microscopy (CLSM).Fifteen periodontally-diseased teeth were extracted, treated with scaling/root planing and longitudinally cut to obtain 30 root fragments. Fragments were treated either with 24% EDTA following application of enamel matrix derivative (EMD), 24% EDTA or EMD only, nanocrystalline hydroxyapatite (NHA) paste or oily calcium hydroxide suspension (OCHS) for 1 h each. The analogue untreated root specimens served as controls. Root fragments were incubated with human PDL fibroblasts and cellular pro…
Histologic Evaluation of Human Intrabony Defects Following Non-Surgical Periodontal Therapy With and Without Application of an Enamel Matrix Protein …
2003
Background: Surgical periodontal treatment with enamel matrix protein derivative (EMD) has been shown to promote periodontal regeneration. However, it is not known whether nonsurgical periodontal therapy with additional subgingival application of EMD may also enhance periodontal regeneration. The purpose of this study was to clinically and histologically evaluate healing of human intrabony defects following non-surgical periodontal treatment with and without application of EMD. Methods: Sixteen patients, each of whom displayed one advanced intrabony defect around teeth or roots scheduled for extraction, were included in the study. The defects were treated as follows: 1) scaling and root pla…
