Clinical evaluation of a flowable resin composite in non-carious Class V lesions: two-year results.

This in vivo study evaluated the clinical performance and appearance of a flowable resin composite and a hybrid resin composite over two years. Twenty-eight (28) pairs of restorations of a flowable resin composite and a conventional hybrid resin composite were placed in non-carious, asymptomatic facial Class V lesions. The restorations were evaluated at baseline, six, twelve, eighteen and twenty-four (6, 12, 18 and 24) months, using modified Ryge/USPHS criteria.

Postmortem dental radiography.

Comparison of postmortem and antemortem dental radiographic films or digital images is a common procedure for establishing identity of human remains. This article describes some problems with producing postmortem dental radiographs in a medical examiner setting and gives methods for circumventing these difficulties. Resection of the jaws, when permitted, significantly simplifies the postmortem radiographic technique.

Comparison of the use of a toothpick holder to dental floss in improvement of gingival health in humans.

Background: Although advances have been made in modulation of host inflammatory response in periodontal therapy, it is important to control the bacterial challenge to the host immune system through conventional therapy and improvement of personal oral hygiene. Although toothbrushing is generally performed, interdental cleaning is not as common. This study compared the use of dental floss to a toothpick holder in the improvement of gingival health.

Effect of surface roughness of cavity preparations on the microleakage of Class V resin composite restorations.

This study determined whether surface roughness of the internal walls of a Class V resin composite preparation, using a carbide bur, a medium-grit diamond bur and a fine-grit diamond bur, affected the degree of microleakage of the restoration. The facial and lingual surfaces of 45 non-carious extracted human molars provided 90 samples for evaluation. The specimen surfaces were assigned randomly in equal numbers to one of three groups (n = 30).
