The heat-seal strength and failure modes of laminated films with Linear Low Density Polyethylene (LLDPE) and Low Density Polyethylene (LDPE) as the sealant materials were investigated. Heat-seal strength increases with platen temperature for all samples. The maximum achievable heat-seal strength for laminated film using LDPE and LLDPE as sealant material is 0.598 N/mm and 4.02 N/mm, respectivel...

Glass ionomer based materials are clinically popular in several areas of restorative dentistry, but restoration of cervical lesions has proven particularly successful. Various etiologies, conformations, locations and structural characteristics make non-carious cervical lesions more challenging to adhesive restorative procedures and marginal seal in the long run. Due to their characteristics, gl...

Over the past 50 years, many changes have occurred in restorative materials in development and on availability.1 Restorative dentistry, in its infancy, was dominated by the simple principle of “Extension for Prevention,” laid down by GV Black and which was partially dictated by the restorative material available at that time.2 Restoration in primary teeth differs from the permanent teeth becaus...

introduction: marginal seal integrity is important for a successful adhesive dental restoration. alterations caused by laser irradiation in the enamel and dentin surface can affect the marginal integrity of adhesive restorations. the aim of this study was to evaluate the microleakage of a composite resin restoration in primary teeth following laser irradiation of enamel and dentin. methods: for...

Title of dissertation: TWO ESSAYS ON TRUST IN SUPPLY CHAIN MANAGEMENT Koray Özpolat, Doctor of Philosophy, 2011 Dissertation directed by: Professor Martin E. Dresner Robert H. Smith School of Business In this dissertation, I propose that trust is an important yet under-studied concept in supply chain relationships both upstream in a Business-To-Business (B2B) context and downstream in a Busines...

pulpal health, waiting for gingival healing from periodontal and oral surgery, waiting for implants to integrate, and evaluating aesthetic and functional changes, to name a few. Some of the clinical requirements of provisional cements are: (1) good retention – it is desirable to have enough retention for long-term provisional cementation, yet not be so retentive that is difficult to remove the ...

Adv Dent & Oral Health 4(1) : ADOH.MS.ID.555628 (2017) Introduction Traumatic dental injuries are common among pediatric dental patients. Approximately 20-30% of children have suffered dental injuries by the age of 12 [1]. Intrusion injuries, though considered rare in the permanent dentition [2], are seen more frequently in the pediatric population [3]. Intrusion is defined as a displacement of...

OBJECTIVE To measure serum cardiac troponin I (cTnI) concentrations in orphaned harbor seal (Phoca vitulina) pups at various points during rehabilitation in a seal rescue center and determine whether cTnI concentration was associated with survival during rehabilitation and duration of rehabilitation. DESIGN Serial cross-sectional study. ANIMALS Fifty-five 2- to 9-day-old harbor seal pups. PROCE...
