Effects of silane coupling treatment on the clinical performance of direct repaired resin-based composite (RBC) restorations with or without prior surface sandblasting: A randomized controlled trial.

Objective: To evaluate the effects, of using silane coupling agent within the procedures of repairing old composite restorations with or without sandblasting their surfaces, on the clinical performance of repaired composite restorations.

Methods: The study involved repairing 130 Class I and II defective composite restorations. After recurrent caries removal, the repair process included etching with 37 % phosphoric acid, Adper Single Bond 2 application for bonding and Filtek Z250 composite for restoring all defects.

Postoperative sensitivity in posterior restorations restored with self-adhesive and conventional bulk-fill resin composites: A randomized clinical split-mouth trial.

Objective: To compare the postoperative sensitivity (POS) of a self-adhesive bulk-fill resin composite with that of a conventional bulk-fill resin composite in posterior restorations.

Methods: Class I and II (n = 166) cavities of at least 3 mm depth, in 83 participants were restored by: (TEST: Surefil one™ Self-Adhesive bulk-fill (n = 83); and CONTROL: Filtek™ Bulk-Fill posterior composites (n = 83). The presence and intensity of POS associated with the restorations was evaluated at 24 h, 1 week and 1 month intervals using the Visual Analogue Scale (VAS).

Satisfaction with Dental Appearance and Attitude toward improving Dental Esthetics among Patients attending a Dental Teaching Center.

Aim: The aim of this study was to evaluate the factors influencing the satisfaction of dental appearance and attitude toward treatments to improve dental esthetics among patients attending a dental teaching center.

Methods: A questionnaire was used to collect data of four background variables among 450 patients attended a dental teaching center in the city of Irbid in Jordan. The questionnaire enclosed self-reported questions about the appearance of anterior teeth, received esthetic treatment and desired treatment for improving esthetics.

Assessing the irradiance delivered from light-curing units in private dental offices in Jordan.

Background: The authors conducted a study to examine the irradiance from light-curing units (LCUs) used in dental offices in Jordan.

Methods: Two of the authors visited 295 private dental offices (15 percent) in Jordan and collected the following information about the LCUs: age, type (quartz-tungsten-halogen or light-emitting diode), date of last maintenance, type of maintenance, last date of use, number of times used during the day, availability of a radiometer, exposure time for each resin-based composite increment, size of light-curing tips and presence of resin-based composite on the tips. The authors used a radiometer to measure the irradiance from the LCUs.
