Evaluation of Effect of Different Insertion Speeds and Torques on Implant Placement Condition and Removal Torque in Polyurethane Dense D1 Bone Model.

The aim of this study was to evaluate the effect of two different insertion speeds at eight different insertion torque values ranging from 25 to 60 during implantation in a dense polyurethane (PU) D1 bone model on the placement condition and removal torque of dental implants. In this study, 50 pcf single-layer PU plates were used. In the study, a total of 320 implant sockets were divided into two groups, Group 1 (30 rpm) and Group 2 (50 rpm), in terms of insertion speed.

A New Approach to Implant Stability Using a Flexible Synthetic Silicate-Additive Beta-Tricalcium Phosphate-Poly(D,L-lactide--caprolactone) Bone Graft: An In Vitro Study.

The aim of this study was to evaluate the use of a flexible synthetic polymer bone graft to provide implant stability during implant placement in a dense cortical bone model. In the control group (Group 1), sockets were prepared on polyurethane blocks according to the standard implant socket drilling protocol; both oversizing and deepening were applied in Group 2; and only oversizing was applied in Group 3. In Groups 2 and 3, flexible synthetic polymer bone grafts were placed in the sockets prior to implant placement.

Factors Influencing Burnout Syndrome and Depression in Dentists across Various Institutions.

: This study aimed to identify the occupational and personal factors influencing burnout syndrome (BS) and depression among dentists in academic faculties, oral and dental health centres (ODHCs), and private clinics. : This prospective, cross-sectional study was carried out on dentists working in different regions of Turkey. Data were gathered through an online questionnaire hosted on Google Forms.

A close-in giant planet escapes engulfment by its star.

When main-sequence stars expand into red giants, they are expected to engulf close-in planets. Until now, the absence of planets with short orbital periods around post-expansion, core-helium-burning red giants has been interpreted as evidence that short-period planets around Sun-like stars do not survive the giant expansion phase of their host stars. Here we present the discovery that the giant planet 8 Ursae Minoris b orbits a core-helium-burning red giant.

Evaluation of the efficacy of topical rifamycin application on postoperative complications after lower impacted wisdom teeth surgery.

Purpose: This study aimed to evaluate the efficacy of a single-dose topical rifamycin application on postoperative complications after impacted lower third molar surgery.

Materials And Methods: This prospective, controlled clinical study consisted of individuals with bilaterally impacted lower third molars that would be extracted for orthodontic reasons. The extraction sockets were irrigated with 3 ml/250 mg of rifamycin solution in Group 1, while in Group 2 (control group) the extraction sockets were irrigated with 20 ml of physiological saline.

Evaluation of Patients with Post-Traumatic Hearing Loss: A Retrospective Review of 506 Cases.

Objectives: The purpose of the study is to evaluate the audiological, radiological, and examination findings of patients who have been treated for hearing loss (HL) due to head trauma and evaluated in terms of causality to reveal current data, and to highlight the steps to be taken.

Methods: We retrospectively reviewed the reports of cases that had applied for disability with HL due to head injury and had been evaluated by the Forensic Medicine Institute between January 01, 2009 and January 01, 2019.

Results: Of the total cases of head trauma, 52.
