ABSTRACT
The aim of this study was to identify factors influencing edentulous patients' preferences for treatment using conventional or implant dentures (ID). A consecutive sample of 112 patients was selected in a university facility. All patients responded to a questionnaire concerning preferences about treatment and factors influencing preferences for conventional complete dentures (CD), implant-retained overdentures (IRO) and fixed implant-supported prostheses (FISP). Subsequently, a set of 21 questions was presented, and patients were requested to rate the importance of various potential reasons influencing their choice of treatment. Preference for CD was more prevalent for maxilla (52·7%) and mandible (41·1%). Fixed implant-supported prostheses and IRO were preferred for the mandible (FISP=37·5%; IRO=21·4%) rather than maxilla (FISP=27·7%; IRO=19·6%). The most preferred treatment option among the subjects when evaluating both arches was the implant-supported fixed or removable prosthesis (FISP/IRO). A preference for combined upper and lower CD was also commonly reported (39·3%). Factor analysis identified six components that accounted for 72·2% of the total variance: (i) psychosocial benefits, (ii) functional performance, (iii) technical and financial concerns, (iv) post-insertion complaints, (v) removability and (vi) longevity. Technical and financial concerns (cost, complexity, surgery risks and duration of treatment) were more relevant for those who preferred ID (P<0·001). With the exception of post-insertion complaints, all mean scores of component factor loadings were positive for ID. Conventional complete dentures are associated with lower expected outcomes by patients, and cost-related issues are the major factors associated with the preferences for implant treatment of edentulous patients.

Diabetes mellitus is a widespread disease whose frequency increases constantly and is expected to reach alarming levels by the year 2025. Introduction of insulin therapy represented a major breakthrough; however, a very strict regimen is required to maintain blood glucose levels within the normal range and to prevent or postpone chronic complications associated with this disease. Frequent hyper- and hypoglycemia seriously affect the quality of life of these patients. Reversion of this situation can only be achieved through whole organ (pancreas) transplant or pancreatic islet transplant, the former being a high-risk surgical procedure, while the latter is a much simpler and may be accomplished in only 20-40 min. The advantages and perspectives of islet cell transplantation will be discussed, in the light of tissue engineering and gene therapy. Ongoing research carried out in our laboratory, aimed at developing clinical cell and molecular therapy protocols for diabetes will also be focused
