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.

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).

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.

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.
