The aim of this clinical case series was to evaluate the clinical performance of the modified tunnel technique for treatment of multiple gingival recessions in the anterior mandible. A total of 20 patients with 63 Miller Class I and II defects were treated via a modified tunnel technique with subepithelial connective tissue graft. At baseline and 6 months postoperative, recession depth, probing pocket depth, width of keratinized tissue, and gingival tissue thickness were assessed. At 6 months, the results revealed a mean recession coverage of 93...

The case reports presented in this article describe a surgical approach for improving root coverage and regenerative parameters in deep intrabony defects associated with buccal gingival recession. A mandibular canine and a maxillary premolar were treated. The surgical technique consisted of a connective tissue graft (CTG) that was placed and sutured at the inner surface of a coronally advanced envelope flap (CAF), thickening the buccal soft tissue wall of the most coronal extension of the intrabony defect and treated with biomaterials as scaffold...

: While high-throughput-sequencing methods are revolutionizing fungal ecology, recovering accurate estimates of species richness and abundance has proven elusive. We sought to design ITS primers and an Illumina protocol that would maximize coverage of the kingdom Fungi while minimizing non-target eukaryotes. We inspected alignments of the 5.8S and LSU ribosomal genes and evaluated potential primers using PrimerProspector. We tested the resulting primers using tiered-abundance mock communities and five previously characterized soil samples...

The performance of kriging methods in predicting maximum m-day (m = 1, 7, 14, or 30) rolling averages of atrazine concentrations in 42 site-years of Midwest Corn Belt watersheds under two systematic sampling designs (sampling every 7 or 14 d) was examined. Daily atrazine monitoring data obtained from the Atrazine Ecological Monitoring Program in the Corn Belt region (2009-2014) were used in the evaluation. Both ordinary and universal kriging methods were considered, with the covariate for universal kriging derived from the deterministic Pesticide Root Zone Model (PRZM)...

BACKGROUND: Oscillating-rotating power toothbrushes have been proven to be clinically efficacious. To the best of the authors' knowledge, a clinical evaluation of the safety of these toothbrushes after surgical root coverage procedures has not been published. The aim of this study is to evaluate the gingival margin (GM) stability with the use of an oscillating-rotating toothbrush compared with a manual toothbrush. METHODS: Sixty healthy individuals with at least one Miller Class I or II gingival recession underwent a surgical root coverage procedure...

While a number of new vaccines have been rolled out across the developing world (with more vaccines in the pipeline), cold chain systems are struggling to efficiently support national immunization programs in ensuring the availability of safe and potent vaccines. This article reflects on the Clinton Health Access Initiative, Inc. (CHAI) experience working since 2010 with national immunization programs and partners to improve vaccines cold chains in 10 countries-Ethiopia, Nigeria, Kenya, Malawi, Tanzania, Uganda, Cameroon, Mozambique, Lesotho and India - to identify the root causes and solutions for three common issues limiting cold chain performance...

A variety of periodontal plastic surgical techniques have been proposed to obtain root coverage of gingival recession defects. All of the available root coverage procedures are able to provide significant root coverage for Miller Class I and II recession-type defects. However, only the subepithelial connective tissue graft in conjunction with a coronally advanced flap appears consistently effective across all clinical parameters, and is therefore currently considered the gold standard for gingival recession therapy...

Irreversible pulpitis is the most common reason for endodontic treatment in primary and permanent teeth. Root canal therapy and extraction are the two viable and most documented treatment options for the same. Studies with regards to management of mature permanent teeth with carious exposure and treatment with vital pulp therapies such as adult permanent tooth pulpotomy are scarce. However, permanent tooth pulpotomy with the new calcium-silicate based cements (Mineral Trioxide Aggregate and Biodentine) can help preserve the tooth pulp vitality and promote healing and repair foregoing the more invasive root canal therapy procedure...

BACKGROUND: The most effective method for treating gingival recessions (GR) is with an autogenous connective tissue graft (CTG) via flap surgery. Often, however, the amount of CTG that can be grafted is insufficient to cover all of a patient's gingival recessions at one time. OBJECTIVES: The objective of this study was to provide a 6-month comparative assessment of the results of covering multiple Miller Class I and II gingival recessions with a Fascia Lata Allograft (FL) and a CTG harvested from palatal mucosa...

Certain cell populations within periodontal tissues possess the ability to induce regeneration, provided they have the opportunity to populate the wound or defect. Guided regeneration techniques have been investigated for regenerating periodontal tissues and such therapies usually utilize barrier membranes. Various natural and synthetic barrier membranes have been fabricated and tested to prevent epithelial and connective tissue cells from invading while allowing periodontal cells to selectively migrate into the defect...

PURPOSE: The aim of the present study was to evaluate the effect of the build angle and the support configuration (thick versus thin support) on the dimensional accuracy of 3D-printed full-coverage dental restorations. MATERIALS AND METHODS: A full-coverage dental crown was digitally designed and 3D-printed using stereolithography-additive manufacturing (SLA-AM) technology. Nine different angles were used during the build process: 90, 120, 135, 150, 180, 210, 225, 240, and 270 degrees...

Resin composite materials that are used to restore tooth cervical lesions associated with gingival recessions can hamper healing after root coverage surgeries. This study evaluates the in vitro cytotoxic effect of five resin composites (two commercial and three experimental) on oral mesenchymal stem cells (MSCs) and the persistence of stemness properties in high passage MSCs. Sorption and solubility tests were made for all materials. MSCs were isolated from re-entry palatal and periodontal granulation tissues and were characterized and cultured on composite discs...

The goal of connective tissue grafting is to cover exposed root surfaces with gingival tissues that are stable and have a natural appearance. The use of an acellular dermal matrix (ADM) has been shown to be a successful alternative to the palatal connective tissue graft. Use of a double layer of an ADM has been shown to have stable results for 1 year. Tunnel grafting techniques can yield root coverage with a natural appearing soft-tissue architecture. The purpose of this case report is to demonstrate the use of a modified tunnel technique and a double layer of ADM in the treatment of multiple adjacent gingival recession defects...
