BACKGROUND AND OBJECTIVES Surgical removal of a mandibular impacted third molar is one among the most common oral surgical procedures. The objective of this study was to assess and identify risk indicators influencing extended operation time in relation to the surgical removal of mesioangular impacted mandibular third molar, position A, Class I and to evaluate the incidence of postoperative swe...

PURPOSE Emerging evidence has suggested that platelet-rich plasma (PRP) might be of assistance in the treatment of degenerative conditions of the joints. The aim of the present study was to compare the use of PRP and hyaluronic acid (HA) in the treatment of temporomandibular joint (TMJ) osteoarthritis (OA) with long-term follow-up data. PATIENTS AND METHODS Patients meeting the Research Diagn...

PURPOSE This study aimed to examine the relationship between jaw opening force and hyoid bone dynamics and resting position in elderly individuals based on gender. SUBJECTS AND METHODS Subjects were 36 healthy elderly individuals aged ≥65 years without dysphagia (16 men and 20 women; mean age 75.5 years, range 65-88 years). Videofluorographic images during the swallowing of 10 mL of 40% (w/v)...

Introduction: Angle and internal position of lateral pterygoid muscle leads to contraction over two half of the mandible in maximum opening and protrusion position so it can affects impression prosthetic procedures. The aim of this study was to evaluate the mandibular flexure in two transverse and antro-posterior dimensions. Methods: Seventy edentulous patients at Mashhad Faculty of Dentistry a...

OBJECTIVE To estimate active maximum mouth opening (AMMO) in a Jordanian subpopulation and to study associated factors and relationship to patient's dental conditions. METHODS This cross-sectional study was conducted on 496 patients aged 15-80 years at the University of Jordan Hospital, Amman, Jordan between October 2008 and March 2009. The AMMO was measured as maximum distance between incisa...

PURPOSE The aim of this study was to evaluate the relationship between the width of 3 or 4 fingers of one hand and maximum mouth opening (MMO) in healthy subjects. METHODS One hundred and forty dental students (age 21 to 42 years, mean 27.4 years) participated in the study. The ability of each subject to position 3 or 4 fingers, vertically aligned, between the upper and lower central incisors...

BACKGROUND AND AIM OF THE STUDY In-vitro studies on the ATS heart valve have indicated that valve opening is less in an expanding conduit than in a straight conduit. METHODS Bileaflet valve behavior was studied using a new computational fluid-structure interaction model. A three-dimensional model of the ATS valve was studied in two geometries, simulating the valve in a geometry with sudden ex...

This study was designed to find a method of assessing maximum mouth opening (MMO), using a tool that is proportional to the body size. One hundred two (102) children were selected to participate in the study. MMO, the width of three fingers (index, middle and ring fingers), four fingers (index, middle, ring and little fingers), body height, weight and age of each child were recorded, and the ab...

the effect of steel plate thickness on the repair effectiveness of rc beam is presented in this paper. a total of four beams were tested, one beam repaired by cfrp with a thickness of 1.2 mm and used as a control beam, and three beams repaired by a steel plate. steel plates with a thickness of 2 mm, 3 mm, and 4 mm were used in repairing the beams. the maximum load-carrying capacity, deflection ...
