Changes induced by music therapy to physiologic parameters in patients with dental anxiety.

Introduction: The aim of this study was to determine the effect of music therapy on patients suffering dental anxiety. In addition, a second objective was to determine the correlation between salivary cortisol and other physiologic parameters.

Methods: 34 patients were randomly assigned to the control group and the experimental group.

Academic stress as a risk factor for dental caries.

Objectives: To evaluate the associations between dental caries classified according to the index for decayed, missing and filled teeth (DMFT) and stimulated salivary flow, salivary capacity for oxidation reduction and academic stress in undergraduate dental surgery students aged 18-22 years.

Methods: This research was performed at three time-points: March 2010, September 2010 and March 2011. The sample was composed of 73 students, including 15 male and 58 female subjects.

Perspectives for the use of silver nanoparticles in dental practice.

Nanotechnology has been used for medical applications in several forms, including dental practice with the development of silver nanoparticles (Ag NPs) as a useful tool. The aim of this review was to identify the properties and appliances of Ag NPs in dental practice. Silver compounds and NPs have already been used as dental restorative material, endodontic retrofill cements, dental implants and caries inhibitory solution.
