Indocyanine Green-Assisted and LED-Light-Activated Antibacterial Photodynamic Therapy Reduces Dental Plaque.

Aim: This study aimed to determine the feasibility and first efficacy of indocyanine green (ICG)-assisted antimicrobial photodynamictherapy (aPDT) as activated using LED light to the dental plaque.

Methods: Fifteen healthy adults were assigned to this four-day randomized study. After rinsing with ICG, 100 J/cm of 810 nm LED light was applied to the aPDT-treatment area.

Radiographic outcome of root canal treatment in general dental practice: tooth type and quality of root filling as prognostic factors.

Objective: This study evaluated the radiographic outcome of root canal treatments (RCTs) performed by general dental practitioners (GDPs) with focus on tooth type and quality of root filling.

Materials And Methods: The target population included all patients receiving root filling by GDPs in City of Helsinki in 2010-2011. Equal numbers of each tooth type (anteriors, premolars, molars) by jaw were included, resulting in 426 teeth.

Forms and varieties of research and industry collaboration across disciplines.

Academic scientists' engagement with industry is a central mechanism in university-industry knowledge transfer and the development of collaborative research. However, most empirical studies are limited to researchers in technical disciplines. We extend the analysis beyond engineers to include broader disciplinary fields, including humanists, economists, medicine, biosciences and cross-disciplinary scientists.

Impact of systemic diseases and tooth-based factors on outcome of root canal treatment.

Aim: To investigate the impact of systemic health and tooth-based factors on the outcome of root canal treatment (RCT).

Methodology: The target population consisted of all patients receiving RCT at the Helsinki University Clinic in 2008-2011. The inclusion criteria were diagnosable pre- and postoperative (minimum 6 months after root filling) radiographs and adequate patient records of RCT available.

Impact of type of tooth on outcome of non-surgical root canal treatment.

Objectives: We assessed the impact of type of tooth on the outcome of root canal treatment (RCT) according to factors potentially weakening the prognosis such as preoperative apical periodontitis (AP) and treatment modality (primary or secondary RCT).

Materials And Methods: We scrutinized patient documents including pre- and postoperative radiographs of 640 permanent teeth receiving non-surgical RCT at Helsinki University Clinic in 2008-2011. Of teeth, 44% were molars, 32% premolars, and 24% anterior teeth.
