AIM The aim of the present study was to compare the remaining dental thickness (RDT) in the mesiobuccal root of mandibular first molars at 3 and 7 mm from the anatomic apex after instrumentation with ProTaper, light speed LSX, K3 and M2 and to compare with that of K-files. MATERIALS AND METHODS In this study, 60 extracted, untreated human mandibular first molars with fully formed apices, with...
o bjectives: the aim of this study was to determine the cementum thickness in the first molars of patients with localized aggressive periodontitis (lap) compared to healthy individuals. materials and methods: this case-control study compared eight first molar teeth af-fected by lap with eight third molar teeth of healthy individuals. the teeth were dis- infected by immersion in 10% buffered for...
Apolipoprotein E-knockout (apoE-KO) mice have been used for studying atherogenesis, but the in vivo features including cardiovascular function have not yet been reported. This study aimed to noninvasively evaluate cardiovascular lesions in 6 apoE-KO mice and 6 control (C57BL/6) mice using transthoracic echocardiography performed using an originally developed linear scanner that permits a high-s...
To investigate the influence of post length and amount of remaining root tissue on the fracture resistance of roots restored with fibre posts relined with resin composite. Ninety upper canine teeth were divided into nine groups (n = 10). The post spaces were prepared resulting in different lengths, as follows: group 2/3, preparations with lengths of 10 mm; group 1/2, preparations with lengths o...
The effects of long-term, artificially created, hypofunctional occlusion and its recovery on the morphology of the first molar root in mice have been investigated. C57BL/6J (Jackson Laboratory, Bar Harbor ME, USA) mice were randomly divided according to their periodontal conditions into normal, hypofunctional, and recovery groups (n = 4). In the experimental hypofunctional and recovery groups...
A prospective clinical study of the effects of the physical features of the appendix on perforation.
BACKGROUND Acute appendicitis (AA) is one of the most common surgical emergencies, whosepostoperative morbidity and mortality increase significantly when the appendix perforates. The identification of factors that lead to perforation in these patients might effectively reduce morbidity. In this study, factors associated with perforation in AA were examined. METHODS The study included sixty pa...
INTRODUCTION The purpose of this study was to compare the subcutaneous tissue responses of freshly mixed or set endodontic root canal sealers (i.e. RoekoSeal, AH26, AH Plus) in Wistar Albino rats. MATERIALS AND METHODS Seventy-two male albino rats weighing 200-250g were used. The animals were randomly divided into six groups of 12 rats each. Root canal sealers were implanted in subcutaneous t...
UNLABELLED The search for new instruments to promote an appropriate cervical preparation has led to the development of new rotary instruments such as TripleGates. However, to the best of the authors' knowledge, there is no study evaluating TripleGates effect on the "risk zone" of mandibular molars. OBJECTIVES The aim of this study was to evaluate the effects of a crown-down sequence of Gates-...
Let L be the Laplacian matrix of a tree. We present a graph-theoretic interpretation of the cofactors of order 2 of L. From this, we deduce a description for the inverse of the rooted Laplacian, reflecting the geometry of a branch. Defining the thickness of a branch as the Perron root of this matrix, we present a minimaxcharacterization of the characteristic center of the tree based on the thic...

ABSTRACT BACKGROUND Complete root coverage is one of the primary objectives to be considered when treating gingival recessions. Furthermore, aesthetic demands can be satisfied by soft tissue grafts, the thickness and color of which should not...
