BACKGROUND AND AIM Several dentifrices have shown to be effective in reducing dentine hypersensitivity (DH), but more effective products are needed. The aim of the study was to evaluate the desensitizing efficacy of a new dentifrice based on zinc-carbonate hydroxyapatite (CHA) nanocrystals. METHODS AND MATERIALS Using a double-blind, randomized design,(More)
Pulp inflammation in restored teeth is mainly due to the presence of bacteria or bacterial products introduced by microleakage around the restoration or to the material toxicity. Recent knowledge has permitted a precise identification of the risks for pulpal irritation associated with adhesive materials and procedures. The purpose of this work was to(More)
PepGen P-15 is a combination natural anorganic bovine-derived hydroxyapatite matrix (ABM) coupled with a synthetic cell-binding peptide (P-15). This material has been reported to enhance bone formation in periodontal osseous defects. The aim of this study was to assess the effect of ABM/P-15 on the healing of cortical bone defects in rabbits. Five New(More)
It has been emphasized that an increased oxidative damage can exist in Down syndrome (DS), and that superoxide dismutase (SOD-1) seems to play a role in the pathogenesis of this disorder. We have studied the antioxidant system SOD-1, catalase, glutathione peroxidase (GSH-Px) and reduced glutathione (GSH) in erythrocytes of DS adults in order to evaluate if(More)
BACKGROUND Placement of dental implants in the posterior maxilla has been associated with higher rates of failure that are due, in part, to the poor bone quality of this region. The purpose of the present study was the histologic and histomorphometric evaluation of the bone around a new implant surface treatment created by a deposition of nanometer-sized(More)
A 72-year-old patient underwent the placement of 2 screw-type implants. After 5 months the patient died of a massive stroke, and a block section of the portion of the mandible containing the implants was done. The specimen was treated to obtain thin ground sections. A 1- to 5-micron gap was present between the implant and the healing cover screw, and this(More)
BACKGROUND The aim of this study was to evaluate the predictability of the free connective tissue graft in prosthetically treated patients needing gingival augmentation. The following outcome variables were studied 1) dimensional changes of free connective gingival grafts; 2) color blending with adjacent tissues; and 3) periodontal and marginal health(More)
BACKGROUND The purpose of the present study was the clinical and the histologic evaluation of fresh frozen human bone (FFB) allografts used for maxillary sinus-augmentation procedures. METHODS Ten subjects were treated with maxillary sinus augmentations using FFB. Radiologic measurements were recorded on computed tomography scans preoperatively and 5(More)
Bone augmentation for implant dentistry has become a necessary procedure for a number of edentulous patients. Calvarial bone grafting constitutes an important tool in achieving maxillary augmentation and sinus elevation. Much effort has been directed toward improving graft survival and volumetric maintenance. The purpose of the present study was to evaluate(More)
