Effects of sealant and self-etching primer on enamel decalcification. Part I: an in-vitro study.

Introduction: The objective of this study was to compare the resistance to enamel demineralization between self-etching primer (SEP) and conventional sealant in vitro.

Methods: A total of 120 molar sections were randomly assigned to 3 groups: SEP (Transbond Plus, 3M Unitek, Monrovia, Calif), sealant (Light Bond fluoride-releasing sealant, Reliance Orthodontic Products, Itasca, Ill), or control (no enamel treatment). SEP or sealant was applied following the manufacturer's recommendations.

Instruction in dental curricula to identify and assist domestic violence victims.

Since most domestic violence injuries occur in the head and neck areas, it is critical that dental professionals be prepared to identify, interview, and assist potential victims. The purposes of these surveys in 1996 and 2007 were to investigate U.S.

Accuracy of space analysis with emodels and plaster models.

Introduction: The purposes of this study were to determine the accuracy and speed of measuring the overall arch length and the Bolton ratio, and the time to perform a Bolton analysis for each patient by using software (emodel, version 6.0, GeoDigm Corp, Chanhassen, Minn) compared with hand-held plaster models.

Methods: Models from 30 patients selected from the files of the Department of Orthodontics at West Virginia University were included in this study.

Comparison of bond strength between orthodontic brackets bonded with halogen and plasma arc curing lights: an in-vitro and in-vivo study.

Introduction: This study assessed in-vitro shear bond strength and in-vivo survival rate of orthodontic brackets bonded with either a halogen or a plasma arc light.

Methods: Ninety extracted premolars were divided into 6 groups of 15. Stainless steel brackets were bonded to the teeth by using either a halogen light with a 20-second curing time or a plasma arc light with a 2-, 6-, or 10-second curing time.

The effects of argon laser irradiation on enamel decalcification: An in vivo study.

Enamel decalcification is a significant problem in orthodontic patients. The argon laser has been shown to reduce decalcification during an acidic challenge in vitro. The purpose of this study was to investigate the in vivo effects of argon laser irradiation on enamel decalcification during orthodontic treatment.
