Effect of amalgam corrosion products in non-discolored dentin on the bond strength of replaced composite resin.

Objectives: To evaluate the effect of amalgam corrosion products in non-discolored dentin on the bond strength of replaced composite resin.

Materials And Methods: One hundred and sixty-one Class I cavities were prepared on extracted premolars and divided into seven groups. Group 1: Light-cured composite; Groups 2, 3, and 4: Amalgam stored in 37°C normal saline for respectively 1, 3, and 6 months and then replaced with composite leaving the cavity walls intact.

The degree of color change, rebound effect and sensitivity of bleached teeth associated with at-home and power bleaching techniques: A randomized clinical trial.

Aim: The purpose of the present randomized clinical trial was to evaluate the color change, rebound effect and sensitivity of at-home bleaching with 15% carbamide peroxide and power bleaching using 38% hydrogen peroxide.

Materials And Methods: For bleaching techniques, 20 subjects were randomized in a split mouth design (at-home and power bleaching): In maxillary and mandibular anterior teeth (n = 20). Color was recorded before bleaching, immediately after bleaching, at 2 weeks, 1, 3 and 6 month intervals.

Inflammatory response of canine gingiva to a chemical retraction agent placed at different time intervals.

Background: Exposure of the gingival sulcus while controlling hemorrhage is prerequisites for maximizing treatment outcomes of cervical carious lesions and for obtaining quality impressions for the fabrication of indirect restorations with cervical finish lines. Gingival retraction cords saturated with different chemical agents are widely used for this purpose. The aim of this study was to investigate and compare the inflammatory potential of 15.

Fracture resistance of premolar teeth restored with silorane-based or dimethacrylate-based composite resins.

Statement Of Problem: To restore posterior teeth using low-shrinkage composite to minimize microleakage.

Purpose: To compare the fracture resistance of mesio-occlusal-distal (MOD) cavity preparations restored with either low-shrinkage composite or with dimethacrylate-based composite in conjunction with cavity liners and without them. The null hypothesis of the study is that there are no differences in either fracture resistance or fracture mode between the silorane group and dimethacrylate groups with and without the use of cavity liners.

The effect of photoactivation time and light tip distance on the degree of conversion of light and dual-cured dentin adhesives.

Background: The degree of conversion of dental adhesive is an important parameter since poor mechanical properties are related to low percentage of monomer-to-polymer conversion within resin-based materials.

Objectives: To evaluate the influence of polymerization time and light guide distance on the degree of conversion (DC) of three contemporary dental adhesives.

Materials And Methods: The spectral data of ExciTE DSC, Single Bond ® , and Adper ® Prompt L-Pop were analyzed using FTIR spectroscopy after 20 s, 40 s, and 60 s of photoactivation times.

Energy dispersive x-ray analysis of corrosion products in nondiscolored dentin and a dye-extraction study of Class 2 composite restorations following amalgam removal.

Objective: To evaluate the effect of corrosion products on the microleakage of composite placed adjacent to nondiscolored dentin after amalgam removal.

Method And Materials: Sixty Class 2 cavities were prepared on extracted premolars, which were divided into four equal groups according to the manner in which they were restored: group 1, light-cured packable composite (Elite LS) to establish a microleakage baseline; group 2, a high-copper amalgam (World Work) previously stored in 37°C normal saline for 6 months to create amalgam corrosion products; group 3, identical to group 2, but the amalgam was later replaced with composite, leaving the cavity walls intact; and group 4, identical to group 3 except the cavity walls were extended 0.5 mm after amalgam removal prior to insertion of the composite.

A retrospective clinical evaluation of success rate in endodontic-treated premolars restored with composite resin and fiber reinforced composite posts.

Background: The aim of this retrospective study was to assess the survival rate and causes of failure of quartz fiber posts used to restore endodontically treated teeth.

Materials And Methods: Thirty-eight patients with endodontically treated premolar and anterior teeth that were then restored with a coronoradicular quartz fiber post and extensive composite resin restorations were selected for participation in the study. The age of the restorations ranged from 1 to 6 years.

The Health Insurance Portability & Accountability Act and the practice of dentistry in the United States: system security.

This article reviews the issues related to the Health Insurance Portability & Accountability Act (HIPAA) security rule that apply to dental practice. The security rule specifically addresses individually identifiable health information that is transmitted or maintained in electronic media. System security must be applied to the entire technical infrastructure for the practice environment as well as to the work culture on a daily basis and must be thought of as an enterprise asset.

The Health Insurance Portability and Accountability Act and the practice of dentistry in the United States: electronic transactions.

This article reviews the kinds of electronic transactions required under the Health Insurance Portability & Accountability Act (HIPAA) and relates them to relevant data contained in an electronic oral health record (EOHR). It also outlines the structure of HIPAA transactions using the claim transaction as an example. The relationship of the HIPAA resource management function to those of patient care are discussed.

The Health Insurance Portability and Accountability Act: practice of dentistry in the United States: privacy and confidentiality.

This paper introduces the reader to the Health Insurance Portability and Accountability Act (HIPAA) of 1996 legislation in the context of its relationship to the Electronic Oral Health Record (EOHR). Privacy and confidentiality issues for administrative data are addressed in terms of the broader relationship of such data to the EOHR leaving the HIPAA-defined administrative transactions and security issues for the entire practice for a subsequent presentation. Educational requirements are presented that aid the dentist and the practice staff in understanding the broad and long-term implications of the HIPAA legislation.

The electronic oral health record.

This paper presents the history of the use of the computer for maintaining patient medical care information. An electronic record generated with a computer, which is non-specific for any healthcare specialty, is referred to as the electronic health record. The electronic health record was previously called the computer-based patient record.
