Investigation of Oxidative-Stress Impact on Human Osteoblasts During Orthodontic Tooth Movement Using an In Vitro Tension Model.

In recent years, there has been a growing number of adult orthodontic patients with periodontal disease. The progression of periodontal disease is well-linked to oxidative stress (OS). Nevertheless, the impact of OS on orthodontic tooth movement (OTM) is not fully clarified.

Pre- and Post-Operative Quality of Life in Patients with Osteoradionecrosis of the Jaw.

Osteoradionecrosis of the jaw (ORNJ) is a feared complication following radiation therapy performed for oncological treatment of head and neck cancers (HNC). To date, there is no clear evidence regarding the impact of surgical treatment of ORNJ on the quality of life (QoL) of affected patients. However, understanding the significance of the surgical treatment approach and its effects on QoL is an essential factor in the decision-making process for optimal, individualized therapy.

Accuracy of maxillary positioning using computer-designed and manufactured occlusal splints or patient-specific implants in orthognathic surgery.

Objective: To determine the accuracy of maxillary positioning using computer-designed and manufactured occlusal splints or patient-specific implants in orthognathic surgery.

Material And Methods: A retrospective analysis of 28 patients that underwent virtually planned orthognathic surgery with maxillary Le Fort I osteotomy either using VSP-generated splints (n = 13) or patient-specific implants (PSI) (n = 15) was conducted. The accuracy and surgical outcome of both techniques were compared by superimposing preoperative surgical planning with postoperative CT scans and measurement of translational and rotational deviation for each patient.

The Novel Monoclonal IgG-Antibody AB90-E8 as a Diagnostic Tool to Rapidly Distinguish from Other Human Pathogenic Species.

In most cases, invasive aspergillosis (IA) is caused by , though infections with other spp. with lower susceptibilities to amphotericin B (AmB) gain ground. , for instance, is the second leading cause of IA in humans and of serious concern because of its high propensity to disseminate and its in vitro and in vivo resistance to AmB.

Lymph nodal recurrence in levels IV and V in oral squamous cell carcinoma after neck dissection.

Background: The aim of the study was to determine the risk of lymph node recurrence in levels IV and V after tumour resection and neck dissection of level I-III and level I-V.

Methods: Data from 228 patients suffering from OSCC were analysed retrospectively. Patients with level I-III neck dissection were compared to those with level I-V neck dissection in terms of number and location of nodal recurrence.
