The aim of our work was to expand on the knowledge concerning mild Traumatic Brain Injuries (TBI), by combining numerical modeling and animal experiments within a joint approach. A three-dimensional finite element model of the rat brain and braincase was developed, and experimental acceleration pulses were applied. Pulse data were obtained from tests(More)
The objective of the study was to better understand the biomechanics of mild traumatic brain injuries (TBI) using a hybrid approach: experiments and computational modeling. A three-dimensional finite element model of the rat skull and brain was used to understand the anatomical region-dependent stress response under mild TBI conditions. Anesthetized rats(More)
The capacity of photo-sensitizers, used in combination with laser light to kill micro-organisms has been demonstrated in different studies. Photo-activated disinfection (PAD) has been introduced in periodontology as an aid for disinfection of periodontal pockets. The aim of this study is to verify the harm for dental vitality of the use of PAD in(More)
Photo-activated decontamination (PAD) has been reported in caries treatment as an aid in dentine decontamination. The aim of this study is to verify the harmlessness for pulp vitality of photo-activated decontamination (PAD) in caries treatment. Twenty freshly extracted single-rooted teeth were used. Deep class I cavities with a <or= 0.5 mm dentine(More)
The aim of this study was to determine whether it is safe to use photo-activated disinfection (PAD) during root canal treatment without heating the periodontal tissues. Root canals of 30 freshly extracted single-rooted teeth were prepared using ProFiles up to size ISO 40 and then filled with photo-sensitiser: tolonium blue (1.2 mg/l). The 635 nm diode laser(More)
In this study, we compared the microleakage of composite fillings cured with halogen bulb, LED and argon ion laser (488 nm). Twenty-four extracted human molars were divided randomly in three groups. Six cavities were prepared on the coronal part of each tooth. Standard cavities (1.7 x 2 mm) were prepared. Cavities were acid etched, sealed with Scotch Bond 1(More)
