Prescription safety eyewear: impact studies of lens and frame failure.
OBJECTIVES To determine if a plano lens could be the test lens for all prescription (Rx) lenses and to investigate why Rx lenses pop out of safety eyewear. DESIGN Plano and Rx polycarbonate lenses (n = 641) with varying thickness and edge geometry, mounted on steel lens holders, and Rx safety eyewear (n = 128) placed on headforms were impacted with test objects of varying diameter and hardnes...
متن کاملFracture Strength of Severely Damaged Primary Anterior Teeth after Restoration with Composite Resin and Resin-Modified Glass Ionomer Cement
Background and Aim: Restoration of primary anterior teeth with severe caries extending to the gingival margin is challenging for many clinicians especially in uncooperative children. Resin modified glass ionomer cements (RMGICs) can be suitable for use in such cases since they require fewer application steps than composite resins. This study aimed to assess the fracture strength of severely dam...
متن کاملIn Vitro Effect of Zirconia and Zirconia Enriched Glass Fiber Composite Posts on Fracture Resistance of Endodontically Treated Teeth
Objective: Despite the advantages of esthetic posts, lack of studies on their fracture resistance has limited their clinical use. This study aimed to compare the effect of two types of esthetic posts namely zirconia and zirconia enriched glass fiber composite posts on fracture resistance of endodontically treated teeth against compressive forces. Methods: This in vitro study was conducted o...
متن کاملبررسی مقایسهای خارج دهانی استفاده از سه نوع گلاس آینومر به عنوان لاینر چسبنده در افزایش مقاومت شکست دندانهای ترمیم شده با آمالگام
Statement of Problem: Because dental amalgam does not adhere to tooth structure, using adhesive cements in amalgam-bonded restorations have been increased. Purpose: The goal of this in-vitro study was to compare the effects of three types of glass ionomer as adhesive liners as well as varnish liner in increasing fracture resistance of teeth restored with amalgam. Materials and Methods: Seventy ...
متن کاملEnhancing Skid Resistance of Two-Component Road Marking Paint using Mineral and Recycled Materials
Low skid resistance of road marking paint is one of the major issues in the safety of vehicle drivers, cyclists, and pedestrians when traveling on the city streets. Among the variety of marking paint, two-component paint is widely used at intersections and roundabouts. Therefore, the paint used should have adequate skid resistance. The object of this study was to evaluat...
