OBJECTIVE: Platelet-rich fibrin (PRF) contains a variety of growth factors and bioactive molecules that play crucial roles in wound healing and angiogenesis. We aimed to evaluate the effects of PRF on tissue thickness and vascularization of the palatal donor site by ultrasound (USG) following subepithelial connective tissue harvesting. METHODOLOGY: A subepithelial connective tissue graft was harvested from the palatal region with a single incision for root coverage in 20 systemically healthy patients...

PURPOSE: Organ transplantation is an effective treatment for children with severe heart, liver, and kidney diseases. These patient groups may have more oral and dental diseases than healthy controls. It is important to eliminate oral infection foci before transplantation and to maintain good oral health to avoid potential post-transplant complications. The aim of this study was to describe and compare oral health in Finnish paediatric heart, liver, and kidney transplant recipients prior to organ transplantation...

OBJECTIVE: To identify radiographic findings suggestive of drug-induced osteonecrosis and evaluate radiomorphometric patterns indicative of changes in bone mineral density in individuals transplanted for liver disorders using bisphosphonates. STUDY DESIGN: The study group included panoramic x-rays of liver transplant patients who are being monitored and who present a clinical status of osteoporosis and use bisphosphonates. The control group was made up of liver transplant patients who did not have osteoporosis...

OBJECTIVES: Poor oral health and dental infections can jeopardize medical treatment and be life-threatening. Due to this, patients with head and neck malignancies, generalized tumor spread, organ transplant, or severe infection are referred for a clinical oral and radiographic examination. The aim of this study was to compare the diagnostic agreement of three radiographic modalities: intraoral radiographs (IO), panoramic radiographs (PX), and cone beam computed tomography (CBCT) for diagnosis of dental diseases...

Graft-versus-host disease (GVHD) is a complication of hematopoietic stem cell transplantation (HSCT). GVHD may also develop following solid transplants or blood transfusions if white blood cells are transferred. GVHD affects multiple organs, including the oral tissues. This pictorial review provides a background of GVHD to dental practitioners, describes the most common oral manifestations of GVHD, and highlights the main treatment modifications needed to deliver dental care to patients with GVHD. A narrative review enriched with clinical data was performed by searching the scientific literature for all articles regarding GVHD and oral manifestations/therapies...

AIM: The aim of this study was to review Japanese laws regarding regenerative medicine and the current status of clinical application of regenerative medicine, to learn about the advantages and problems, and to thereby serve as a reference for measures necessary for the development of regenerative medicine. BACKGROUND: Regenerative medicine started in 1957 with the transplantation of hematopoietic stem cells, followed by the establishment of embryonic stem cells in 1981 and induced pluripotent stem cells in 2006, and continues to evolve progressively...

Early dental screening and treatment before and after solid organ transplantation are recommended infection prophylaxis measures. Dental treatment after transplantation should only be rendered after a discussion with the patient's health-care provider and/or transplant surgeon to determine the patient's stability for dental care. Potential sources of acute or chronic oral infections should be evaluated at every visit. Periodontal evaluation and through dental prophylaxis should be performed. Oral hygiene instruction including the importance of maintaining excellent oral health after transplant should be reviewed...

INTRODUCTION: The oral cavity is one of the most common sites impacted by hematopoietic stem cell transplantation (HSCT) with acute complications including mucositis, bleeding, salivary gland dysfunction, infection, and taste alteration. These complications may result in significant morbidity and can negatively impact outcomes such as length of stay and overall costs. As such, oral care during HSCT for prevention and management of oral toxicities is a standard component of transplant protocols at all centers...

In Hungary, there are around 3500 people living with a transplanted organ, there are around 400 total donations, including between 250 and 300 kidney transplants per year. Due to the development of immunosuppression and surgical techniques, the survival rate of patients has improved, and therefore dentists are increasingly confronted with gingival hyperplasia due to immunosuppressive therapy in addition to oro-dental lesions resulting from renal failure. The prevalence of gingival hyperplasia with cyclosporin A can be as high as 90%...

PURPOSE: To assess the prevalence of oral manifestations in a group of allogenic liver, kidney or haematopoietic stem cell transplantation recipients and patients, and analyze the possible oral manifestations associated with the use of 4 immunosuppressive drugs. METHODS: One hundred and eighteen patients submitted to liver, kidney and hematopoietic stem cell transplantation who used tacrolimus， sirolimus，cyclosporine or mycophenolate mofetil were enrolled. Through a questionnaire survey and oral examination, their oral manifestations were recorded, and the possible statistical associations with immunosuppressive drugs were analyzed using SPSS 21...

MATERIAL AND METHODS: This study is based on data of patients referred to the Department of Oral and Maxillofacial Surgery of the University Hospital Erlangen, Germany, prior to kidney transplantation between January 2015 and March 2020...

Generalized eruptive syringomas are a very rare variant of syringoma which appear on the chest, neck, abdomen, upper and lower arms, thighs, legs and back. They often affect adolescent or post-adolescent females, although cases have been described in children and older adults. Generalized eruptive syringomas are mostly sporadic but familial cases, and those associated with eczematous skin conditions, solid organ transplants, renal cell carcinoma and some genodermatoses have also been reported. Although eruptive syringomas may resemble cutaneous mastocytosis, disseminated granuloma annulare, eruptive xanthomata, steatocystoma multiplex, eruptive velus hair syndrome, verruca plana and other skin conditions clinically, the histological appearance characterized by upper dermal epithelial cords with a tendency to ductule formation and tadpole extension of outer epithelial layer is diagnostic...

Patients with special needs (SNPs) include individuals who are disabled due to physical limitations, medical complications, developmental problems, and cognitive impairments. SNPs may be at an increased risk of oral diseases throughout their lifetime. These patients have difficulties in accessing traditional dental studios or clinics. Moreover, orodental problems may cause local and generalized infections, leading to worrisome complications when not properly treated. In this paper, we describe the preliminary experience of treating dental problems in a series of nine hospitalized patients with special needs...

BACKGROUND/AIMS: Pre-transplant blood transfusions have previously shown a positive effect on organ allograft survival in humans and various animal species. The aims of this study were, first, to evaluate the effect of pre-transplant donor-specific blood transfusions on periodontal healing of fully developed allotransplanted teeth in monkeys; and second, to investigate the immune response against donor antigens and to determine a possible correlation between alloimmune reactions and histopathological signs of rejection...

The Alagille syndrome (AGLS) is a rare condition, with few studies reported in the literature, especially in the field of dentistry. It consists of a disease involving many systemic problems and specific facial features. The liver and heart are the most intensely affected organs, and depending on the severity, it may be necessary to perform transplants. It is an autosomal dominant disease with a variable expressivity, and its prevalence is 1/100,000 live births. Dental findings are conflicting. Some authors claim that dental anomalies occur only in deciduous dentitions; however, there is evidence that permanent teeth can also be affected, as will be described in this paper, through a case report of a patient diagnosed with AGLS, who sought out the Dentistry service at Pontifical Catholic University of Minas Gerais, complaining of a strong stain in her teeth, severe dental crowding, and a facial appearance of prognathism...
