Sinus lift elevation restores bone mass at the maxilla in edentulate patients before the placement of dental implants. It consists of opening the lateral side of the sinus and grafting beta-tricalcium phosphate granules (β-TCP) under the olfactory membrane. Bone biopsies were obtained in five patients after 60 weeks. They were embedded undecalcified in poly(methyl methacrylate) (pMMA); blocks were analyzed by nanocomputed tomography (nanoCT); specific areas were studied by Raman microspectroscopy. Remnants of β-TCP were osseointegrated and covered with mineralized bone; osteoid tissue was also filling the inner porosity...

BACKGROUND: There has been growing interest in the potential for adverse immunologic reactions to metals in biomedical devices and increasing referrals for the evaluation and management of metal hypersensitivity reactions reported in orthopedic, cardiac, gynecologic, and dental implant devices. However, there are few studies that give evidence-based recommendations on how to evaluate this issue in our practices. METHODS: We reviewed reasonable evidence and expert opinion on biomedical device hypersensitivity and published guidelines on pre- and postimplantation evaluation of delayed hypersensitivity reactions in patients suspected of possible metal hypersensitivity to biomedical devices...

Odontogenic myxoma (OM) is a non-metastasizing neoplasm of mesenchymal origin, arising in the tooth-bearing areas of the jaws. When regarding the whole spectrum of differential diagnoses for osteolytic jaw lesions, OM constitutes a benign tumor rarely located in the maxilla. Radiographically, displacement of teeth and frequent involvement of the sinus will be found with advanced maxillary OM. The tumor can be removed by means of several techniques, ranging from conservative measures to extended surgical procedures that differ according to type of bone resection and reconstruction of the defect...

Oral squamous cell carcinoma (OSCC) is the most common cancer of the oral cavity and constitutes 95% of all cancers of this area. Men are affected twice as commonly as women, primarily if they are over 50 years of age. Forty percent of the lesions are localized in the tongue and 30% in the floor of the oral cavity. OSCC often affects upper and lower gingiva, buccal mucous membrane, the retromolar triangle and the palate. The prognosis is poor and the five-year survival rate ranges from 20% (OSCC in the floor of the mouth) to 60% (OSCC in the alveolar part of the mandible)...

After tooth loss, an individual may seek tooth replacement so that his/her function and esthetics could be restored. Clinical prosthodontics, during the past decade, has significantly improved and developed according to the advancements in the science and patient's demands and needs. Conventional options in prosthodontics for substituting a missing single tooth include the removable partial denture, partial and full coverage bridgework, and resin-bonded bridgework. Dental implants have gained increasing popularity over the years as they are capable of restoring the function to near normal in both partial and completely edentulous arches...

BACKGROUND: Keratin has shown promising outcomes as a biomaterial due to its inherent bioactivity, biocompatibility and regenerative effects. The effect of keratin on repair and regeneration of dental tissues has never been studied before. Current therapies to treat pulp tissues involve its replacement with inert, synthetic materials that do not have a proper biological function, leading to failure and tooth loss. This study aimed to develop a biocompatible keratin hydrogel (KH) suitable for pulp therapies...

Periodontics cannot be practiced in isolation as frequently many patients have multiple dental needs or medical health issues requiring management. In addition, pathology may manifest in the periodontal tissues, and the onset and progression of periodontitis can be affected by systemic conditions, such as diabetes, and vice versa. The focus of this volume of Periodontology 2000 is interdisciplinary periodontics, and the articles included discuss the interactions and the interrelationshipbetween periodontal tissues/periodontal diseases and endodontics, fixed prosthodontics, implant dentistry, esthetics, gerodontology, radiology, orthodontics, pediatric dentistry, oral and maxillofacial surgery, oral pathology, special needs dentistry and general medicine...

Dental implants are regularly placed in patients with a history of periodontitis, even though peri-implant tissues are susceptible to the same host-modulated plaque-induced factors that initiate and sustain periodontitis. This article endeavors to clarify the evidence regarding the history of periodontitis as a risk factor for implant success and survival, and the role of supportive periodontal therapy in maintaining implants for individuals with a history of periodontitis.

Melatonin is a hormone synthesised and secreted by the pineal gland and other organs. Its secretion, controlled by an endogenous circadian cycle, has been proven to exert immunological, anti-oxidant, and anti-inflammatory effects that can be beneficial in the treatment of certain dental diseases. This article is aimed at carrying out a review of the literature published about the use of melatonin in the dental field and summarising its potential effects. In this review article, an extensive search in different databases of scientific journals was performed with the objective of summarising all of the information published on melatonin use in dental diseases, focussing on periodontal diseases and dental implantology...

Yttria-stabilized tetragonal zirconia (Y-TZP) has been proposed as a potential dental implant due to its good biocompatibility, excellent mechanical properties, and distinctive aesthetic effect. However, Y-TZP cannot form chemical bonds with bone tissue because of its biological inertness, which affects the reliability and long-term efficacy of Y-TZP implants. In this study, to improve the bioactivity of Y-TZP ceramics while maintaining their good mechanical performance, Y-TZP was modified by grain boundary activation via the infiltration of a bioactive glass (BG) sol into the surface layer of Y-TZP ceramics under different negative pressures (atmospheric pressure, -0...

Complex periprosthetic cases are considered as challenges by clinicians. Clinical and radiographic parameters should be considered separately to make the right choice between an endodontically or periodontally compromised treated tooth and implant. Therefore, in order to decide whether the tooth is safe or not, data that have to be collected are specific parameters of both the patient and the clinician. In addition, the presence of periodontal, prosthetic, and orthodontic diseases requires patients to be set in multidisciplinary approach...
