The investigators hypothesize that there are microbiological differences in bacterial samples collected from tongue /or lip piercings made of different materials. The investigators also hypothesize that the piercings carry the same characteristic bacteria as found in the piercing channels and that independently the biofilm on the t...

Class II Restoration Using Bioactive Restorative Material vs Polyacid Modified Composite Resin in Primary Molars

Successful restoration of cavities in primary molars can be considered challenging. It is different from restoring cavities in permanent molars because factors such as the level of co-operation of the child and the handling properties and setting time of the restorative material will have some influence on the success rate of the restoration. The ideal requirements that a filling material should possess include that it bears the occlusal force, withstands the acidic and bacteri...

Horizontal Ridge Augmentation in Mandible Usign ROG + ESWT

Guided bone regeneration (GBR) has been the most frequently used option to treat bone ridge deficiencies, allowing to restore such defects in order to place bone-integrated dental implants. A few reports exist in the literature about the augmentation of mandibular horizontal ridge defects before implant placement. Published studies show a large variability of reported results regarding horizontal bone augmentation. This can be due to the use of different types of membranes and ...

Evaluation of Cerebral Elastography by Magnetic Resonance: Comparison of Healthy Subjects and Patients With Glial Tumor

MRI elastography detects the movement of tissues in the human body and monitors their response to mechanical stress in order to reveal their mechanical properties, like palpation. These depend on the structure of the tissues, their biological conditions and possible conditions. This non-invasive technique allows exploration of deep organs such as the brain that the doctor's hand can not reach. MRI elastography may prove to be an essential tool for study, diagnosis, staging and ...

Soft Peri-implant Tissue Around Different Abutment Materials

Soft tissue attachment to the implant surface serves as a biological seal preventing the development of inflammatory periimplant diseases (i.e. peri-implant mucositis and peri-implantitis).It occurs in the presence of a biomaterial during healing of the surgical wound that might be influence by this foreign body. Myofibroblasts represent key players in the physiological reconstruction of connective tissue after injury. This work will focus on the role of myofibroblasts during ...

Filling of Tooth Sockets With MBCP Gel TM Versus Technical Without Filling

After a dental extraction, the osseous alveoli fill naturally of a blood clot which is transformed some month later into osseous tissues. Even if the alveolar walls remain intact at the end of the intervention, the healing always comes along with a physiological reduction at the level of the site. The reduction of the alveolar crests is a continuous, cumulative and inexorable phenomenon This reduction entails in the long term aesthetic and functional damages which complicate th...
