INTRODUCTION: Recently, greater emphasis has been placed on smile esthetics in dentistry. Eye tracking has been used to objectively evaluate attention to the dentition (mouth) in female models with different levels of dental esthetics quantified by the aesthetic component of the Index of Orthodontic Treatment Need (IOTN). This has not been accomplished in men. Our objective was to determine the visual attention to the mouth in men with different levels of dental esthetics (IOTN levels) and background facial attractiveness, for both male and female raters, using eye tracking...

In dentistry, methods for determining age and the degree of dental and skeletal development play an important role, in particular in the assessment of developmental disorders of the dentition as well as in the planning of orthodontic interventions. Dentistry is also important in the field of forensics due to the possibility of age determination based on the dentition. In addition to anthropometric and morphologic methods, numerous biochemical, histologic, radiologic, and radiation-free imaging methods exist to determine the chronologic, but also dental and skeletal age of a person or a patient...

Osseointegrated implants have been recognized as being very reliable and having long-term predictability. However, host defense mechanisms against infection have been known to be impaired around a dental implant because of the lack of a periodontal ligament (PDL). The purpose of our experimental design was to produce cementum and PDL on the implant surface adopting cell sheet technology. To this aim we used PDL-derived cells, which contain multipotential stem cells, as the cell source and we cultured them on an implant material constituted of commercially pure titanium treated with acid etching, blasting, and a calcium phosphate (CaP) coating to improve cell attachment...
