Attitudes of dentists toward maintaining, repairing, or replacing direct composite resin restorations.

This study aimed to report the reasons for replacement of direct composite resin restorations in dental practices in Brazil. The study used a convenience sample of 213 dentists. A questionnaire was developed from previously validated instruments and sent electronically to prospective participants.

Clinical evaluation of two packable posterior composites: a five-year follow-up.

Background: Research has suggested that packable resin-based composites inserted with a placement technique similar to amalgam condensation can reduce the sensitivity associated with posterior restorations. The authors evaluated the clinical performance, including associated sensitivity, of two packable composites in a randomized five-year clinical trial.

Methods: A single operator randomly placed two restorations in each of 33 patients: one restoration consisting of Alert (Jeneric/Pentron, Wallingford, Conn.

Indirect pulp treatment in a permanent molar: case reort of 4-year follow-up.

This case report describes the Indirect Pulp Treatment (IPT) of deep caries lesion in a permanent molar. A 16-year-old male patient reported discomfort associated with thermal stimulation on the permanent mandibular left first molar. The radiographs revealed a deep distal caries lesion, very close to the pulp, absence of radiolucencies in the periapical region, and absence of periodontal space thickening.

Comparison of two minimally invasive methods on the longevity of glass ionomer cement restorations: short-term results of a pilot study.

The purpose of this study was to evaluate the clinical performance of glass ionomer cement (GIC) restorations comparing two minimally invasive methods in permanent teeth after 12 months. Fifty pregnant women (second trimester of pregnancy), mean age 22 +/- 5.30 years, were treated by two previously trained operators.

Influence of occlusal access on demineralized dentin removal in the atraumatic restorative treatment (ART) approach.

Purpose: To verify the influence of cavity access diameter on demineralized dentin removal in the ART approach.

Methods: 40 non-carious human premolars were randomly divided into four groups. The occlusal surface was ground flat and the teeth were sectioned mesio-distally.

Clinical evaluation of multiple-surface ART restorations: 12 month follow-up.

Purpose: The purpose of this study was to evaluate the performance of multiple-surface restorations employing 2 different glass ionomer cements (GICs) and the Atraumatic Restorative Treatment (ART) approach in permanent molar teeth.

Methods: This study examined 60 restorations--36 Class I restorations involving 2 or more tooth surfaces and 24 Class II restorations--that were placed in 46 schoolchildren (9-16 years of age) by 2 dentists using the ART approach. The restorations were randomly divided into 2 groups: (a) 30 cavities were filled with high strength GIC (Ketac Molar-3M ESPE), and (b) 30 cavities were filled with resin-modified GIC (Fuji VIII-GC Corp).

The use of CVD diamond burs for ultraconservative cavity preparations: a report of two cases.

Unlabelled: During the past decades, scientific developments in cutting instruments have changed the conventional techniques used to remove caries lesions. Ultrasound emerged as an alternative for caries removal since the 1950s. However, the conventional technology for diamond powder aggregation with nickel metallic binders could not withstand ultrasonic power.

Influence of ultrasonic setting on tensile bond strength of glass-ionomer cements to dentin.

Purpose: The aim of this study was to evaluate the influence of ultrasonic treatment on the bond strength of glass-ionomer cements to dentin.

Materials And Methods: Conventional (Fuji II: a; Ketac-Fil Plus: b), resin-modified (Fuji II LC Improved: c; Photac-Fil Quick Aplicap: d), and more viscous conventional (Ketac Molar: e) glass-ionomer cements were tested. Fifty human molars were sectioned mesiodistally, embedded in epoxy resin with exposed buccal or lingual surfaces, and ground to obtain a flat dentin surface.
