(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-11-28)
Aim:<br> The aim of this multicentre, parallel-group randomized clinical trial was to compare the effectiveness of mineral trioxide aggregate (MTA) and a conventional calcium hydroxide liner (CH) as direct pulp capping materials in adult molars with carious pulpal exposure.<br> Methodology:<br> Seventy adults aged 18–55 years were randomly allocated to two parallel arms: MTA (White ProRoot, ...
Light-curing units used in dentistry: factors associated with heat development – potential risk for patients
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-10-01)
Objectives:<br>To investigate how heat development in the pulp chamber and coronal surface of natural teeth with and without cusps subjected to irradiance using light-emitting diode (LED)–light-curing units (LCUs) is associated with (i) irradiance, (ii) time, (iii) distance, and (iv) radiant exposure.<br> Materials and methods:<br>Three different LED-LCUs were used. Their irradiance was measured ...
Dental anxiety: A comparison of students of dentistry, biology and psychology
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014-09-23)
Dental anxiety is an important challenge for many patients and clinicians. It is thus of importance to know more about dental students’ own experiences with dental anxiety and their understanding of dental anxiety. The aim was to investigate differences in dental anxiety levels between dental students, psychology students, and biology students at a Norwegian university.
Language of motivation and emotion in an internet support group for smoking cessation: Explorative use of automated content analysis to measure regulatory focus
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
The present study describes a novel approach to the identification of the motivational processes in text data extracted from an Internet support group (ISG) for smoking cessation. Based on the previous findings that a “prevention” focus might be more relevant for maintaining behavior change, it was hypothesized that 1) language use (ie, the use of emotional words) signaling a “promotion” focus would ...
Investigational Clinical Trial of a Prototype Optoelectronic Computer-Aided Navigation Device for Dental Implant Surgery
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06)
Purpose: New digital technologies enable real-time computer-aided (CA) three-dimensional (3D) guidance during dental implant surgery. The aim of this investigational clinical trial was to demonstrate the safety and effectiveness of a prototype optoelectronic CA-navigation device in comparison with the conventional approach for planning and effecting dental implant surgery. Materials and Methods: ...

Surface properties of dental zirconia ceramics affected by ultrasonic scaling and low-temperature degradation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-13)
Zirconia (3Y-TZP) dental prostheses are widely used in clinical dentistry. However, the effect of ultrasonic scaling performed as a part of professional tooth cleaning on 3Y-TZP dental prostheses, especially in conjunction with low-temperature degradation (LTD), has not been fully investigated. The present study aimed to evaluate the influence of ultrasonic scaling and LTD on the surface properties ...
