Confirmation of the mandibular canal is clinically important to avoid local injury to the nerve during surgical and endodontic rocedures. Especially, it is crucial to identify the anatomic location of the mental foramen. The mental nerve is a somatic afferent sensory nerve of the mandibular nerve that emerges from the mental foramen and which presents as a single circular, or elliptical, bilateral radiolucent area in the premolar region. The evaluations of accessory foramina that relate to the mandibular canal are clinically important in endodontic treatments and surgical procedures such as dental implant insertion, implant-related bone grafting, genioplasty and mandibular anterior segmented osteotomy. The accessory mental nerve is a relevant anatomic structure in dental practice with particular importance for local anesthes. The mental foramen (MF) is a small foramen located in the anterolateral region of the mandible through which the mental nerve and vessels emerge. The knowledge on the anatomic characteristics and variations of MF is very important in surgical procedures involving that areaia and surgical procedures involving this region, such as genioplasty, surgical rehabilitation after mandibular trauma, bone harvesting from the chin, root resection of mandibular premolars, and particularly the placement of dental implants. Two-dimensional radiographs are the most frequent imaging method in the dental field, but intraoral and rotational panoramic radiograph (PAN) images often fail to depict anatomic variations in the MF area. Presurgical tridimensional assessment using computed tomography (CT) could be a more useful tool for determining the presence of AMF. In particular, cone beam computed tomography (CBCT) provides sufficient resolution to allow accurate evaluation of osseous landmarks in the maxillofacial region and presurgical detection of AMF. Thus in this study the Panoramic radiography and cone beam CT will compare to identify of of mental foramen.

The increase of human’s time of life increases the need for biomaterials replacing parts of human body or organs. The study of the biointegration of alloplastic materials and development of biocompatible materials is one of the most important research fields of biomedical sciences. Biomaterials or alloplastic materials are synthetic materials used to make devices to replace part of a living system or to function in intimate contact with living tissue. They cannot trigger any toxic and unwanted reaction in the host system.

During the science student circle we plan to investigate the biointegration of dental implants. These implants are artificial replacements of a missing tooth which is made of Titanium (Ti) and are one of the most common medical implants. During biointegration the biomaterial gets in direct contact with the living tissues, it has to be functional for a long time and cannot be harmful for its biological environment (Park, 2000).

The successful biointegration of implants depend from many factors: bulk and surface characteristics, construction (design) and the biocompatibility of the material. Beside this the applied surgical technique, general health condition and life-quality of the patient are also decisive. Biocompatibility is the acceptance of a synthetic material or an artificial implant by the surrounding tissues and by the body as a whole (Park, 2000). The proposed research topic will focus on the surface aspects and biocompatibility of these implants.

We are conducting a study on our clinic about computer assisted intraosseal anesthesia, for the better understanding of its indications, efficiency and postoperative complications.  The aim of our research is to compare this technique with the routinely used infra alveolar nerve block.

During the research every volunteer receives an infra alveolar nerve block anesthesia and a computer assisted intraosseal anesthesia in different appointments. The efficiency of the technique is controlled by cold spray test, and an anonym questionnaire is filled in by the volunteers.  The results of questionnaires will be evaluated.
