Probable collagenous gastritis via Epstein-Barr virus reactivation in the setting of coronavirus disease 2019: a case report.

Background: Recent biomedical research has shown the unusual, multisystem effects of coronavirus disease 2019 in humans. One specific sequela of a primary severe acute respiratory syndrome coronavirus 2 infection is the reactivation of latent viruses in various tissues, such as Epstein-Barr virus. Epstein-Barr virus has been identified in many inflammatory gastrointestinal lesions, such as microscopic gastritides and colitides.

Impact of Clear Aligners vs Conventional Brackets on Oxidant and Antioxidant Levels: A Case-Control Study.

BACKGROUND The aim of this study was to identify the changes in the levels of total oxidant status (TOS) and total antioxidant status (TAS) in gingival crevicular fluid (GCF) samples of patients treated with conventional brackets (CBs) and clear aligners (CAs) over a 30-day period. MATERIAL AND METHODS Thirty-four patients who received non-extraction treatment with either CBs or CAs were included in the study. GCF samples were obtained at baseline (T0) and on days 7 (T1) and 30 (T2) following initial phase of treatment.

Polygraphic evaluation of the effects of different rapid maxillary expansion appliances on sleep quality: A randomized clinical trial.

Background: The purpose of this clinical study was to assess the effects of different rapid maxillary expansion appliances on the severity of obstructive sleep apnea (OSA).

Material And Methods: Patients having a narrow maxilla and identified with OSA were divided randomly into three groups: tooth tissue-borne, tooth-borne, and bone-borne expanders. Changes in sleep parameters at baseline and 3-month follow-up detected by polygraphy were the primary outcome.

Evaluating the effects of orthodontic treatment with clear aligners and conventional brackets on mandibular condyle bone quality using fractal dimension analysis of panoramic radiographs.

Objective: Orthodontic treatment carried out with clear aligners has become a method that is preferred by patients. In this study, the effect following orthodontic treatment with clear aligners and with conventional brackets, on the mandibular condyle trabecular bone formation is aimed to be examined.

Materials And Methods: Thirty two individuals (16 females and 16 males) with a mean age of 16.

Evaluation of the effects of different rapid maxillary expansion appliances on airway by acoustic rhinometry: A randomized clinical trial.

Objective: The purpose of this 3-arm parallel trial was to compare the effects of tooth tissue-borne (TTB), tooth-borne (TB) and bone-borne (BB) rapid maxillary expansion (RME) appliances on nasal airway with acoustic rhinometry (AR).

Setting And Sample Population: Forty-six 12- to 14-year-old patients with narrow maxilla were randomly allocated into 3 study groups accordingly the type of expander: TTB, TB and BB. The participants were recruited from the Department of Orthodontics, Izmir Katip Celebi University.
