Bleeding Complications in Relation to the International Normalized Ratio for Dental Extractions in Patients under Chronic Anticoagulant Therapy - An Evaluative Study.

Introduction: Recent simple dental extraction protocols suggest that therapeutic levels of the anticoagulant drug should be maintained because bleeding complications could be managed with local haemostasis manoeuvres. The aim of the present study was to evaluate the association between bleeding complications and the international normalized ratio (INR) values in patients after dental extractions completed with a plug of bismuth subgallate, without interrupting anticoagulant administration.

Materials And Methods: Patients undergoing oral Vitamin K antagonist chronic anticoagulant therapy requiring simple dental extractions were included in the study.

Dental Emergency Admissions in Emergency Oral Health Care Centers during COVID-19 Pandemic in Buenos Aires, Argentina.

This study aimed to describe patients' demographic characteristics and treatment delivered in private and public dental emergency clinics and to compare them with a pre-pandemic period. A retrospective cross-sectional study was carried out on patients attending the University Dental Hospital of the University of Buenos Aires and on one private dental clinic, situated in Buenos Aires, between March and June of 2019 and 2020. The sample considered all the patients' medical records of those requiring emergency dental treatment at these centers during that period.

Trigeminal nerve injuries. Four years' experience at a single Argentine referral center and a literature review.

The aim of this retrospective study was to describe the etiology and characteristics of trigeminal nerve injuries referred to a specialized center in Buenos Aires, Argentina. A retrospective analysis was performed of patients referred from February 2016 to January 2020. Age, sex, intervention performed, nerve affected, time elapsed from injury, diagnosis, location, and whether patient had signed informed consent were recorded.

Randomized Clinical Trial Comparing Three Local Hemostatic Agents for Dental Extractions in Patients under Chronic Anticoagulant Therapy - A Comparative Study.

Introduction: Oral anticoagulants are widely used worldwide for many systemic diseases. Recent oral surgical protocols suggest that therapeutic levels of the anticoagulant drug should be maintained for simple dental extractions because bleeding complications could be managed with proper local hemostasis. The aim of the present study was to compare bleeding complication of three different local hemostatic agents for dental extractions without interrupting drug administration in patients undergoing oral Vitamin K antagonist chronic anticoagulant therapy.

Titanium dental implant-related pathologies: A retrospective histopathological study.

Objectives: To perform a retrospective, descriptive, histopathological study of peri-implant tissue pathologies associated with titanium dental implants (TDI), and to evaluate the presence of metallic particles in samples from a single diagnostic center.

Methods: Sixty-eight cases of TDI-associated lesions were retrieved from the Surgical Pathology Laboratory archives, School of Dentistry, University of Buenos Aires (UBA) (1990-2018). The study included re-examining the histopathological features of the biopsy samples, analyzing the inflammatory infiltrate, and examining the samples to detect metallic particles whose chemical composition was determined spectrophotometrically (EDS).

Assesment of SARS-CoV-2 infection-in dentists and supporting staff at a university dental hospital in Argentina.

Introduction: Oral healthcare professionals are at increased risk of infection by SARS-CoV-2. The aim of this study was to evaluate the prevalence of COVID-19 in a population of workers who provided services during the COVID-19 pandemic at a dental care and educational institution in the Buenos Aires Metropolitan Area.

Materials And Methods: This was a descriptive, cross-sectional study including 358 workers who provided essential services during the first 180 days of the COVID-19 pandemic at the Dental Hospital at Buenos Aires University School of Dentistry (FOUBA).

Cervicofacial Infections Caused by .

() is an opportunistic pathogen that causes a wide range of diseases. Dissemination of perioral infections is a common problem in the field of oral and maxillofacial surgery. The aim of the study was to evaluate carriage in the oral cavity and its dissemination to different cervicofacial regions.

Sebaceous cyst in the oral cavity.

Sebaceous glands are reported to be normally located in the oral region in the vermilion of the upper lip and on the buccal mucosa. They are small yellowish bodies located immediately beneath the mucosa, and although numerous pathologies of these tissues have been described, very few clinical reports have been made. Pathologies such as ectopic location, hyperplasia, adenomas, carcinomas, and cysts have been described.

[Fungal invasion of connective tissue in patients with gingival-periodontal disease].

Background: In the last few years unusual microorganisms have been isolated from subgingival biofilm, as possible initiators or contributors to periodontal disease, especially in patients who show no improvement during treatment.

Aims: To study the Candida invasion of the connective tissue in relation to subgingival biofilm presence.

Methods: A total of 55 immunocompetent patients of both sexes, between 21 and 55 years of age, non-smokers, without previous antimicrobial treatment, suffering periodontal diseases, were studied.

Use of anorganic bovine bone matrix in an experimental model of bone healing.

The dimensions of the alveolar bone surrounding the tooth are not maintained post tooth-extraction probably as a consequence of the bone remodeling process and the biomechanical demands on bone. The use of biomaterials as bone substitutes in the post-tooth-extraction socket promotes bone repair, regardless of damage to bone structures during the surgical procedures. The aim of the present study was to evaluate the effectiveness of anorganic bovine bone matrix (ABBM) as a bone substitute, in an experimental model of post-tooth extraction bone healing in the rat.
