Uremic stomatitis is an underreported disease that occurs in the oral mucosa, associated with high levels of blood urea in patients with chronic kidney disease. This case report describes a 36-year-old male patient with severe and multiple oral manifestations of uremic disease. Intraoral examination revealed ulceration, atrophic and hemorrhagic areas were seen on the ventral surface of the tongue, floor of the mouth, and buccal mucosa.

Introduction: Medication-associated osteonecrosis of the jaws (MRONJ) is characterized by the presence of exposed bone or an intraoral or extraoral fistula in the maxillofacial region in patients with a history of treatment with anti-resorptive and anti-angiogenic drugs, such as monoclonal antibodies, and without a history of radiotherapy or metastatic diseases in the area.

Objective: The aim of this study is to report a case of a pathological mandibular fracture in an area of MRONJ in a patient diagnosed with Crohn's disease treated with infliximab.

Case Report: A 53-year-old male patient, an active smoker for 35 years, diagnosed with Crohn's disease, undergoing intravenous administration of infliximab 300 mg for 1 year and 3 months, with no previous history of anti-angiogenic or anti-resorptive medication, presenting with an extraoral fistula in the submandibular region for 4 months, with painful symptoms, diagnosed as MRONJ.

Objective: Assess the impact of photobiomodulation therapy (PBMT) on xerostomia, salivary flow rate (SFR) and composition in patients undergoing radiotherapy (RT) for head and neck cancer (HNC).

Study Design: Thirty patients undergoing RT (65 Gy) for HNC were enrolled. Saliva and xerostomia evaluations collected pre- and post-PBMT-RT.

Parameter reproducibility in photobiomodulation therapy (PBMT) is still scarce in literature for the management of oral mucositis (OM). This study aimed to identify the most used PBMT dosimetry parameters (DP) and their efficacy in OM management after preconditioning for hematopoietic stem cell transplantation (HSCT). This research was conducted according to the PRISMA guidelines.

Background: Viral reactivation in patients undergoing immunosuppressive therapy after hematopoietic stem cell transplantation (HSCT) is a serious complication associated with significant morbidity and mortality. Infections caused by human herpes viruses such as herpes simplex virus (HSV), cytomegalovirus (CMV), and Epstein-Barr virus (EBV) can result in oral lesions.

Case Presentation: A 40-year-old male patient who had undergone HSCT presented with ulcerated lesions in different areas of the mouth, for 7 months.

Background: Schizophrenia (SCZ) presents complex challenges related to diagnosis and clinical monitoring. The study of conditions associated with SCZ can be facilitated by using potential markers and patterns that provide information to support the diagnosis and oral health.

Methods: The salivary composition of patients diagnosed with SCZ (n = 50) was evaluated and compared to the control (n = 50).

Aims: The aim of this study was to compare individuals with and without schizophrenia through the characteristics of the palate, such as width, length, depth, palate shape, and upper dental arch shape.

Methods And Results: The sample was divided into one case group (n = 45) and two control groups (n = 90; 45 individuals each group). Groups were paired by variables: sex, age, and malocclusion type.

Purpose: The purpose of this study was to evaluate bone repair with two bone substitutes, deproteinized bovine bone and biphasic calcium phosphate ceramics, associated with autogenous bone.

Materials And Methods: The experimental groups were as follows: autogenous bone only (AB), autogenous bone/deproteinized bovine bone (1:1), and autogenous bone/biphasic calcium phosphate ceramic (1:1). After 30, 60, and 90 days, animals were euthanized and samples were collected for microcomputed tomography (micro-CT), histologic, histomorphometric, and expression analyses of VEGFA, RUNX2, ALP, COL1A1, OCN, PHEX, RANKL, and OPG genes by real-time polymerase chain reaction (PCR) array.

Objectives: The aim of this study was to verify the likely influence of presurgical administration of low doses of alendronate sodium in craniofacial bone repair and correlate the histological frame found on reparative tissue to the immunohistochemical presence of IGF1, IGF2, and osteopontin (OP).

Materials And Methods: In total, 120 rats were randomly allocated into four groups: group C (control), group OA (autogenous bone), group B (bisphosphonates), and group OA-B (autogenous bone + bisphosphonates). Groups B and OA-B received alendronate sodium (ALN) 0.

The aim of this study was to evaluate the stress and dislodgement resistance by finite element analysis of different types of fixation in mandibular orthognathic surgery. A 3D solid finite element model of a hemi-mandible was obtained. A bilateral sagittal split osteotomy was simulated and the distal segment was advanced 5 mm forward.

Introduction: Bone graft is a very common procedure that is performed when bone volume needs to be increased before a dental implant. Screws and miniplates are the clinical standards for osteosynthesis. However, some disadvantages for this method have been reported, including artifacts on radiological images, infection, screw loosening, and the need to remove screws that interfere with the dental implants.

Purpose: This study evaluated the immunohistochemical presence of Indian Hedgehog (IHH), transforming growth factor-β (TGF-β), and parathyroid-1 receptor (PTH1R) in calvaria bone repair, and compared these results with the histological bone matrix features in defects treated with autograft in the presence or absence of L-PRP.

Material And Methods: An artificial bone defect measuring 5 × 1 mm was produced in the calvaria of 28 Wistar rats. Randomly the defects were treated with autograft and autograft mixed with L-PRP.

Xanthoma is a very rare bone tumor, especially in the mandible, that can be associated with metabolic diseases such as hyperlipidemia. A 14-year-old girl presented with a non-corticated unilocular radiolucent lesion observed on panoramic radiography. The lesion was located between the roots of the left first and second premolar teeth, extending from the cervical to the apical region, measuring approximately 1 cm in greatest dimension.

Background: This study evaluated the osteoconductive effect of an autograft, in the presence or absence of the L-PRP, using histomorphometric analysis of the bone formed, and we compared the results in the presence of TGF-β1, Wnt10b and CD34 detected by immunohistochemistry.

Materials And Methods: Two bone defects were produced in the calvaria of 20 rabbits. The defects were treated with autograft and autograft combined with L-PRP.

Objective : This study analyzed the influence of autogenous white adipose tissue on bone matrix development in critical-size defects created in rabbit calvaria. Materials and methods : A 15-mm-diameter defect was created in the calvaria of 42 rabbits. Twenty-one rabbits were treated with 86 mm(3) of immediate transplant of fragmented white subcutaneous adipose tissue (WSAT); the others constituted the control group (sham).

Background: Detection and quantification of human papillomavirus (HPV) may help in predicting the evolution of HPV infection and progression of associated lesions.

Objectives: We propose a novel protocol using consensus primers GP5+/6+ in a SYBR Green quantitative real-time (Q-RT) polymerase chain reaction (PCR). The strategy permits screening for HPV infection and viral load quantification simultaneously.

Bell"s palsy is a neuropathy of the peripheral seventh cranial nerve, resulting from traumatic, compressive, infective, inflammatory or metabolic abnormalities or it can be idiopathic. HIV, Epstein-Barr virus and hepatitis B virus have been suspected as initiating organisms, but herpes simplex virus is the most frequently implicated. This report describes 2 cases of Bell"s palsy in children that were managed with antiviral agents.

Fanconi's anemia (FA) is a genetic autosomal recessive disorder, characterized by progressive bone marrow failure, congenital abnormalities, growth retardation, and predisposition to leukemia and solid tumors. The purpose of this study was to compare the chronological age (CA), bone age (BA), and dental age (DA) of FA patients and to determine whether the therapy received influenced the BA or DA. Thirty FA patients were evaluated and divided into three groups according to the therapy received.
