Background: The aim of this in vitro research was to compare and evaluate the stability of TADs coated with PRP over 6 months. TAD stability is essential for the long-term success of orthodontic treatment. PRP has become a valuable adjunct to promote healing in many procedures of oral surgery.
View Article and Find Full Text PDFBackground: The aim of this study was threefold. Firstly, it aimed to introduce and detail a novel method for chemically etching the bases of stainless-steel orthodontic brackets. Secondly, the study sought to investigate the structural alterations within the brackets' microstructure following chemical etching compared to those with sandblasted bases, using electron microscopy analysis.

Methods: Maxillary arches of 92 patients with Class II Division 1 malocclusion requiring premolar extractions were randomly distributed to receive both types of Ti-6Al-4V alloy TADs by a single operator. TADs were replicas of each other except for the HA precipitation surface coating of the threaded part.
European anchovy, a small pelagic fish, plays a significant role in the blue economy, with remarkable commercial, ecological and culinary values. In this study, the variability in the shapes of the body and sagitta otoliths was examined to identify the different anchovy stocks in the Black Sea (26.5°E-39.

Thus, this study aimed to fill this knowledge gap via examination of 414 sagittal otoliths from 108 male (total length 13.8-26.

Methods: Thirty patients with skeletal Class II Division 1 malocclusion requiring anchorage from TADs for retraction of maxillary incisors into the extracted premolar space were recruited in this parallel group, split-mouth, randomized controlled trial. A block randomization sequence was generated with Random Allocation Software (version 2.
Gastric evacuation (GE) experiments were performed on brook trout Salvelinus fontinalis fed commercial food pellets. The experiments included small fish (36 g; 15 cm total length, LT ) fed meals of 0·2, 0·4 and 0·8 g and large fish (152 g; 23 cm) fed meals of 0·8, 2·0 and 4·0 g at temperatures ranging from 15·1 to 18·2° C. The stomach contents were thereafter sampled and weighed at 3 h intervals until the first empty stomach was observed.

Methods: A retrospective review of the case notes of 15 patients who presented to three regional oculoplastics units over a 7-year period were reviewed. Patient demographics, clinical characteristics, relevant medical history, microbiology results, imaging, management and outcomes were assessed.

Purpose: Previous studies have extensively investigated the pathophysiology, genetics, and lifestyle risk factors of thyroid-associated ophthalmopathy (TAO). The aim of this study was to investigate the independent contribution of ethnic origin, social grade, and level of social deprivation to TAO severity in a large, multiethnic, and urban population.
Methods: Retrospective case note review of all TAO patients seen at Birmingham and Midland Eye Centre, United Kingdom over a 14-year period.
Background: The Internet is a vital source of information for patients hoping to learn more about their disease. Health literacy of the general population is known to be poor, with the U.S.

Unlabelled: Correction of deep bite by intrusion of incisors is an important and cumbersome target to achieve. This article describes an easy and rapid method of fabricating a custom made nickel titanium intrusion arch to achieve this objective.
Clinical Relevance: A custom made intrusion arch is more effective, comfortable, easily available and cost effective than a preformed one.
Purpose: To evaluate the postoperative infection rate after external dacryocystorhinostomy (DCR) without routine systemic antibiotic prophylaxis.
Methods: Retrospective review of case notes, including eye casualty attendances, of 77 patients undergoing 82 consecutive external DCR procedures between 22 December 2006 and 31st December 2009 performed by one of the authors (O. M.
Purpose: To describe a new technique for deep lateral (single) wall orbital decompression surgery, developed by Mr. Geoffrey Rose, for proptosis in patients with thyroid-associated orbitopathy and to analyse the results achieved in our series.
Methods: The study is an interventional, retrospective, non-comparative case series.
Purpose: Small, well-demarcated, biopsy-proven periocular basal cell carcinomas (BCC) are often excised in a single stage with immediate reconstruction when histology or location is considered low-risk. We investigated margin clearance in patients undergoing primary excision and immediate reconstruction (PER) versus multi-staged fast paraffin excision (MSE) and reviewed risk factors for incomplete excision.
Methods: Retrospective, interventional, comparative case series of periocular BCCs excised over a 3-year period (2006-2008).
Angiomatous meningioma is a rare and distinct meningioma variant characterised with predominance of microvascularcomponent.There are few reported cases in literature with limited information on ophthalmic manifestations and radiological findings. There is no consistent feature reported so far of this neoplasm to aid in its diagnosis.

Objectives: The initiating cause of Behçet's disease (BD) is unknown, but an aberrant response to infection has been suggested. In this study, single nucleotide polymorphisms in Toll-like receptors (TLRs) and associated molecules that have a sentinel function at mucosal surfaces were analysed in patients with BD.
Methods: TLR expression was determined by immunohistochemistry in buccal mucosal tissue from patients with BD, in tissue from patients with lichen planus (LP) or pyogenic granuloma (PG) as disease controls, or from healthy individuals.

Increasing number of patients presenting for ophthalmic surgery are using oral anti-coagulant and anti-platelet therapy. The current practice of discontinuing these drugs preoperatively because of a presumed increased risk of bleeding may not be evidence-based and could pose a significant risk to the patient's health. To provide an evidence-based review on the peri-operative management of ophthalmic patients who are taking anti-thrombotic therapy.

One-hundred and sixty extracted human premolars free of any detectable pathology or buccal surface alterations were collected and divided into four groups. In group 1 (control), the teeth were bonded with stainless steel brackets using Transbond XT.
