Additionally, a wide range of procedures and augmentation materials are used in the reconstruction of these osseous defects. The authors present a study including histology of surgical treatment of odontogenic cysts using a biphasic calcium sulfate composite bone graft. \u0000Materials and methods Two groups, study and control, of 30 patients each with odontogenic cyst were treated for radicular cyst removal with reconstructive surgery using a deproteinized bovine bone graft (xenograft). A modified surgical procedure was performed in the control group, with different types of graft placed in the osseous defects. In the study group wound site closure was performed without periosteum cutting to allow stretching of the flap to attempt primary site closure, whereas in the control group primary wound closure was achieved to protect the xenograft material. \u0000Results In the study group complete wound healing and suture maintenance was reported in 29 patients (96.6%); in 1 case (3.4%), a postoperative wound dehiscence (I°) occurred on day 5. In the control group no wounds dehiscences were observed in 24 patients (80%), in 4 cases (12%) a wound dehiscence (I°) occurred on day 3 and 5 and in 2 cases (8%), IIo wound dehiscence over 10 mm with secondary inflammatory features were observed which required graft removal. \u0000Conclusions The use of the Bond Apatite® preparation proved to be a simple, inexpensive and effective reconstructive treatment of osseous defects after enucleation of odontogenic cysts.","PeriodicalId":42724,"journal":{"name":"Journal of Osseointegration","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2020-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88926576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and methods In this study, hydroxyapatite specimen were prepared, two kinds of experiments ( simulation test and animal experiment ) were performed. Hydroxyapatite specimen were soaked in the simulated body fluid (SBF) as a simulation test, implanted rabbits iliac crest as in vivo test. After the irradiation of pulsed ultrasound wave for some planned time–periods, the surface of specimens were assessed and compared with non-ultrasound waving specimens ( control group ) by using Scanning Electron Microscope (SEM), Energy Dispersive Spectroscop (EDS) and X-ray diffraction.Results SEM image and EDS showed that richer layer of bone-like hydroxyapatite covered specimens surfaces in ultrasound wave irradiation group as compared with control group. The measurement of mass of specimens also indicated the efficiency of ultrasound waves for hydroxyapatite formation. These results indicated low intensity ultrasound wave might promote the nucleation and crystallization of bone-like apatite on hydroxyapatite surfaces.Conclusion This study suggested that the clinical application of ultrasound waving has a great potential for enhancement of osseointegration of hydroxyapatite dental implant through the activation of bone bonding mechanism on material surface.","PeriodicalId":42724,"journal":{"name":"Journal of Osseointegration","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2020-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86893880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Osteoarthrosis (non-inflammatory arthritic condition) is an adaptive stage, involving morphologic changes of the articular structures, not associated with significant alterations in the mechanical joint function. Altered articular surfaces of the TMJ may be considered as normal adaptive responses to increased loading, rather than pathological degenerative changes. Polyarthritis or polyarticular arthritis (high–inflammatory arthritic conditions), present similar symptoms and clinical findings as osteoarthritis but have different causes. The classic type of high-inflammatory arthritis is rheumatoid arthritis. \u0000Conclusion The clinician must be aware of the various systemic conditions that may affect the TMJ and the stomatognathic system as a whole. In this way the proposed dental treatment plan can and should be adjusted to the needs of the patient taking under consideration the manifestations of the disease in the stomatognathic system.","PeriodicalId":42724,"journal":{"name":"Journal of Osseointegration","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2020-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73757205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various therapeutic approaches have been described in the literature, the most widely used being surgical enucleation of the lesion associated with extraction of the attached tooth. Some authors propose enucleation of the cementoblastoma with attached tooth preservation. \u0000Case report This case report describes a 32-year-old Caucasian female with two symmetrical mandibular growths, the largest of which was surgically removed together with the attached tooth, while the other was preserved and steadily monitored. After 15 years of follow-up, no recurrence was observed in the surgical site. The preserved lesion maintained the same dimension and radiographic appearance, although after 3 years the attached tooth required endodontic treatment. With continuous monitoring being the primary prerequisite for this therapeutic choice, preservation of the lesion meant that the patient was able to avoid invasive surgical procedures. \u0000Conclusion Our results agree with the theory which describes cementoblastoma as a self-limiting lesion. However, its monitoring is crucial whatever the therapeutic choice might be.","PeriodicalId":42724,"journal":{"name":"Journal of Osseointegration","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2020-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84293851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research labs are joining forces to find a therapy and a preventive vaccine. Preventive and extraordinary safety measures are crucial to reduce the spread of SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus-2) among Health-Care Professionals (HCP). HCP performing or assisting aerosol-generating procedures are classified as “very high exposure risk” workers. New findings suggest that saliva delivered through cough, droplets released through normal breathing and oral mucosa represents a vector of SARS-CoV-2 transmission. Consequently, viruses can be easily vehiculated by most of dental procedures and it is essential for dental offices to change the operating modes. The present narrative review aimed to gather evidence in order to propose operative guidelines to reduce the risk of SARS-CoV-2 transmission in the dental offices. Emphasis was also given to unresolved questions about COVID-19 (Coronavirus Disease 2019) diagnostics and future directions to improve the preventive and safety measures in daily dental practice. \u0000Results Operative guidelines aimed to reduce the risk of transmission in the dental office are drawn and described. \u0000Conclusion A rapid and reliable diagnostic test detecting COVID-19 positive patients upon arrival at the dental office could allow dental HCP to work in “semi-ordinary” conditions; infected or suspected patients would be postponed or treated only in case of a real emergency employing high-level PPE and extraordinary preventive strategies.","PeriodicalId":42724,"journal":{"name":"Journal of Osseointegration","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2020-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91156071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
