Intramuscular cavernous malformation in the temporalis muscle: Diagnosis and treatment of a rare tumor in a rare site.

In this case report we present a very rare case of intramuscular cavernous hemangioma in the temporalis muscle which was successfully managed with surgical excision with no evidence of recurrence in follow-up.

Comparison of three antibiotic protocols for prevention of infection in dental implant surgery: A randomized clinical trial.

This study aimed to compare the rate of post-surgical infection following single-dose antibiotic prophylaxis with or without post-surgical antibiotics versus post-surgical administration of antibiotics alone. The study consisted of three groups; Group 1 received single-dose antibiotic prophylaxis orally (2 g amoxicillin 1 h before surgery). Group 2 received one dose of prophylactic antibiotic (2 g amoxicillin 1 h before surgery) with additional doses after surgery (500 mg amoxicillin, q8h for 5 days).

Effect of different intracanal medicaments on the fracture resistance of the human root.

Background: The effect of different intracanal medicaments on root fracture resistance has not been thoroughly investigated in the short and long term. To assess the effect of calcium hydroxide (CH), CH combined with Chlorhexidine (CHX), double antibiotic paste (DAP), and simvastatin as intracanal medicaments on the fracture resistance of the human root. One hundred and twenty single-rooted mandibular premolars which were extracted for periodontal reasons were collected for this study.

Juvenile trabecular ossifying fibroma of the maxilla: Case report of a diagnostic dilemma.

Ossifying fibromas (OFs) are benign, well-demarcated lesions in the craniofacial region, particularly in the jaws, with clinical, radiographic, and histopathological similarities to other lesions, which make their diagnosis challenging. Herein, we report a case of a fibro-osseous lesion in the anterior maxilla of a 13-year-old boy, consisting of an intraosseous and an extra-osseous part, which created a diagnostic dilemma.

The Effect of Photodynamic Therapy on the Smear Layer Removal: a Scanning Electron Microscopic Study.

Statement Of The Problem: The efficacy of photodynamic therapy (PDT) in smear layer removal compared to the currently accepted protocol is not well established.

Purpose: This study aims to evaluate the effect of PDT on smear layer removal from human root canal compared to combined use of irrigation solutions including sodium hypochlorite (NaOCl) and ethylene diamine tetra acetic acid (EDTA) by scanning electron microscopy (SEM).

Materials And Method: In this study, straight roots from 48 extracted human maxillary incisors and canines were selected and decoronated.

Antiretrovirals for Prophylaxis Against COVID-19: A Comprehensive Literature Review.

Although people living with human immunodeficiency virus and other comorbidities are expected to experience more grievous consequences with corona virus disease 2019 (COVID-19), recent cohort studies did not indicate this. Antiretrovirals (ARVs) might have a prophylactic role in these patients. The purpose of this study was to review the most recently published articles on the possible role of ARVs for pre- or postexposure prophylaxis against COVID-19.

The Effect of a Mineralized Bone Graft on the Surface Microhardness of Mineral Trioxide Aggregate and Biodentine.

Introduction: This study was designed to determine the effect of Osteon II mineralized bone powder on the surface microhardness of two retrofilling materials: Mineral trioxide aggregate (MTA) and Biodentine (BD).

Methods And Materials: Each retrograde material was mixed and carried into 30 sterile custom-made plastic cylinders. Half of the samples in each group were exposed to Osteon II.

Liver disease symptoms in non-alcoholic fatty liver disease and small intestinal bacterial overgrowth.

Introduction: It seems that there is a relationship between small intestinal bacterial overgrowth (SIBO) and non-alcoholic fatty liver disease (NAFLD). The main objective of this study was to evaluate the prevalence of SIBO among NAFLD patients.

Methods: In this descriptive-analytical cross-sectional study, 98 eligible NAFLD patients were evaluated for SIBO using hydrogen breath test (HBT).

Defecographic Findings in Patients with Severe Idiopathic Chronic Constipation.

Background/aims: Chronic constipation is a common gastrointestinal disorder diagnosed using Rome III criteria. Defecography is a radiographic method used to identify anatomic abnormalities of anorectum. The present study aimed to evaluate the defecographic findings in patients with severe idiopathic chronic constipation.

Chromium level in prediction of diabetes in pre-diabetic patients.

Background: Chromium supplementations (Cr) have been shown to exert beneficial effects in the management of type-2 diabetes. Prevalence of Cr deficiency in pre-diabetic patients is not well-understood, therefore, the aim of this study was to evaluate the extent of this prevalence.

Materials And Methods: In this cross-sectional descriptive study, 132 pre-diabetic patients were recruited.

Long-term results of pleurodesis in malignant pleural effusions: Doxycycline vs Bleomycin.

Background: The aim of this study was to compare the response of doxycycline and bleomycin in pleurodesis of malignant pleural effusions.

Materials And Methods: The radiologic and clinical responses of doxycycline and bleomycin in pleurodesis of malignant pleural effusions were compared in this randomized clinical trial. Forty-two patients were randomized to receive either bleomycin 45 mg or doxycycline 600 mg as the sclerotherapy agent.
