Survival rate and complication-free survival rate of implant-retained prostheses in the oral rehabilitation of patients with head and neck cancer: A retrospective evaluation of a cohort from a regional service.

Statement Of Problem: Literature reporting on the prosthetic survival and complications of implant-retained prostheses in patients with head and neck cancer is sparse.

Purpose: The purpose of this retrospective study was to present the survival rates and complication-free survival rates of both fixed and removable implant-retained oral prostheses in patients with head and neck cancer while also reporting on the frequency and causes of failure and complications for each prosthesis type.

Material And Methods: A retrospective analysis of the prosthetic survival rates and complication-free survival rates of implant-retained oral prostheses and the frequency and causes of failure and complications in patients with head and neck cancer treated in a regional unit from 2012 to 2017 was performed.

Prosthodontic complications during implant-based oral rehabilitation of patients with head and neck cancer.

Statement Of Problem: Implant-retained prosthodontic rehabilitation of patients with head and neck cancer is complex. However, the extent of prosthodontic complications has been sparsely reported within the literature.

Purpose: The purpose of this retrospective study was to describe the range of complications and issues that affected the oral rehabilitation treatment of patients with head and neck cancer who had completed implant-retained prosthodontic rehabilitation in a tertiary treatment center.

Outcomes of implant-based oral rehabilitation in head and neck oncology patients-a retrospective evaluation of a large, single regional service cohort.

Background: The study reports on implant survival outcomes in head and neck cancer patients who received implant-based oral rehabilitation in a regional service centre.

Methods: A retrospective analysis of implant survival outcomes in patients treated in a regional service from 2012 to 2017 was performed. The primary outcome measure was implant survival.

Mineral trioxide aggregate use in failing endodontic treatment--a case report.

Unlabelled: Management of failing endodontic treatment may present significant challenges. The following case report describes the use of a contemporary endodontic material--Mineral Trioxide Aggregate (MTA). Successful resolution of endodontic disease was accomplished through a combined orthograde and retrograde approach.

Principles of crown lengthening surgery.

Unlabelled: Crown lengthening is an invaluable tool for the restorative dentist in the management of short clinical crown heights. This procedure, as an adjunct to a holistic restorative treatment plan, can produce predictable results, whilst ensuring good aesthetics and maintaining periodontal health. Crown lengthening procedures are invaluable where toothwear or lack of supragingival tooth substance would render full coverage restoration difficult.

Mucogingival grafting procedures--an update.

Unlabelled: Gingival recession is the exposure of the root surface due to the apical migration of the gingival margin. It is a common feature in the general population and can often lead the patient to seek treatment. Mucogingival therapy may be required to prevent further recession, correct aesthetic problems, aid plaque control and reduce dentine hypersensitivity.

Contemporary periodontal surgery: 2. Surgical practice.

Unlabelled: Contemporary surgical techniques emphasize gentle tissue handling with a minimum of trauma. This in turn provides a predictable operative environment and promotes healing. A modern surgical armamentarium may be very different from that encountered a decade ago.

Contemporary periodontal surgery: 1. Surgical principles.

Unlabelled: Periodontal surgery comprises surgical intervention of the supporting tissues of the teeth. This ranges in complexity from simple exodontia to technically demanding periodontal plastic surgery and includes the management of periodontal diseases, implant placement and preparatory treatment for fixed and removable prostheses. Modern surgical management reflects both a move towards evidence-based practice and the introduction of improved techniques and armamentarium.

Heteroconium sp. nov. from roots of Triticum aestivum in the United Kingdom.

Morphological and molecular studies led to the description of Heteroconium triticicola as a new species isolated from roots of wheat in the United Kingdom. The new fungus shares with H. citharexyli, the type species of Heteroconium Petrak, features such as superficial mycelium, macronematous, mononematous, unbranched, straight conidiophores, monoblastic, integrated, terminal, cylindrical conidiogenous cells, and catenate, dry, simple, cylindrical, obclavate, often pale brown, smooth, multiseptate conidia.

Microdochium triticicola sp. nov. from roots of Triticum aestivum in the United Kingdom.

Morphological and molecular studies led to the description of Microdochium triticicola as new species isolated from roots of wheat in the United Kingdom. The morphological features of all known Microdochium species are tabulated.

Phylogenetic relationships among Zygomycetes from soil based on ITS1/2 rDNA sequences.

New information was obtained on the phylogeny of Zygomycetes. PCR-RFLP analysis showed ITS1/2 rDNA to provide appropriate markers for genetic studies on Zygomycetes at the population and species levels. The use of several restriction enzymes allowed discrimination between genera and species of Mortierellales and Mucorales.

Retention of quartz-fibre endodontic posts with a self-adhesive dual cure resin cement.

This study examines retention of a quartz-fibre endodontic post cemented in extracted human teeth using two cement types. Fifty-four extracted buman central incisor teeth were prepared for a tapered quartz-fibre post. Posts were cemented in 28 teeth using conventional resin cement (RelyX ARC), and 26 teeth using self-adhesive resin cement (RelyX Unicem).

Variation in the effects of take-all disease on grain yield and quality of winter cereals in field experiments.

Relationships between take-all intensity and grain yield and quality were determined in field experiments on cereal crops using regression analyses, usually based on single-point disease assessments made during anthesis or grain-filling. Different amounts of take-all were achieved by different methods of applying inoculum artificially (to wheat only) or by using different cropping sequences (in wheat, triticale or barley) or sowing dates (wheat only) in crops with natural inoculum. Regressions of yield or thousand-grain weight on take-all intensity during grain filling were similar to those on accumulated disease (area under the disease progress curve) when these were compared in one of the wheat experiments.

Mode of action and pesticidal activity of the natural product dunnione and of some analogues.

This paper reports the investigation of the insecticidal and fungicidal activity of dunnione, a natural product obtained inadvertently as a by-product of a synthesis programme. Dunnione exhibits no insecticidal activity but has an unusually broad spectrum of antifungal activity. In vitro and in vivo (preventative) activities were comparable to those of several long-established fungicides (eg carbendazim).

Comparison of Gaeumannomyces- and Phialophora-like fungal pathogens from maize and other plants using DNA methods.

Several DNA-based techniques, developed for identifying and differentiating fungi in the Gaeumannomyces-Phialophora complex associated with take-all diseases of cereals and grasses, were used to compare fungi from maize. Maize isolates obtained as G. graminis (Sacc.
