Longevity and reasons for failure of sandwich and total-etch posterior composite resin restorations.

Purpose: To investigate longevity and reasons for failure of Class II posterior composite restorations (PCRs) placed with or without a lining of glass-ionomer cement.

Materials And Methods: Four hundred fifty-eight Class II PCR placed in 248 patients (110 male, 138 female, age 18 to 80) by two dentists in a general practice between 1988 and 1997 were retrospectively examined from the patient files. The restorations were placed either with a total-etch technique or with a resin-modified glass-ionomer lining placed on the dentin.

A retrospective clinical study on longevity of posterior composite and amalgam restorations.

Objectives: The purpose of this study was to evaluate retrospectively the longevity of class I and II amalgam and composite resin restorations placed in a general practice.

Methods: Patient records of a general practice were used for collecting the data for this study. From the files longevity and reasons for failure of 2867 class I and II amalgam and composite resin restorations placed in 621 patients by two operators between 1990 and 1997 were recorded in 2002.

The effectiveness of bonded composite restorations in the treatment of painful, cracked teeth: six-month clinical evaluation.

This study investigated the clinical efficacy of a bonded resin composite restoration with and without cuspal coverage for the treatment of painful, cracked teeth. Patients in a private dental practice who presented with complaints were selected. Inclusion criteria were sensitivity to cold, biting and a clinically-visible crack after removal of the existing restoration.
