This study aimed to evaluate the biomechanical behaviour of adhesive endo-crowns and the influence of their design on the restoration prognosis when four loading positions are applied from the restoration-tooth junction. Two three-dimensional finite element models for the lower first molar were developed: endo-crown as a monobloc and endo-crown of a primary abutment and a full crown. Four crown...

The aim of this study was to carry out a representative survey on the implementation of and experience with repairs of single-tooth restorations among dentists in the Canton of Zurich, Switzerland. An anonymous questionnaire was sent to all 1,411 dentists registered in the Canton of Zurich; 38.9% of the delivered questionnaires were returned and 35.3% could be evaluated. The statistical analysi...

BACKGROUND Endodontic treatment, involves removal of the dental pulp and its replacement by a root canal filling. Restoration of root filled teeth can be challenging due to structural differences between vital and non-vital root filled teeth. Direct restoration involves placement of a restorative material e.g. amalgam or composite directly into the tooth. Indirect restorations consist of cast m...

OBJECTIVES The aim of the present study was to investigate the prevalence of impacted and supernumerary teeth, apart from third molars. STUDY DESIGN This was a retrospective study of 1.239 panoramic radiographs taken of patients who presented to the Department of Dentoalveolar Surgery, Implantology and Radiology at the School of Dentistry of the Aristotle University of Thessaloniki, Greece be...

The primary objective of the research is to provide detailed information on various social aspects of the Marmara earthquake. In particular, the research focuses on activities aimed at restoring basic social functions to the impacted region during the early recovery phase of the disaster. This paper examines three of those functions: (1) housing, (2) education, and (3) health care. The paper co...

ackground and aim: It is important to evaluate the effect of the type of filling material on deformation and strength of tooth after filling and also the effect of filling depth on quality of restoration of a decayed tooth. Material and Methods: The Orthopantomogram (OPG) of the first and second molars of a 28-year-old man was made and the teeth were 3D modeled. The stress-deformation analysis ...

AIM To investigate the probability of and factors influencing tooth survival following primary (1°RCTx) or secondary (2°RCTx) root canal treatment. METHODOLOGY This prospective study involved annual follow-up of 2 (100%) to 4 years (50%) of 1°RCTx (759 teeth, 572 patients) and 2°RCTx (858 teeth, 642 patients) carried out by Endodontic postgraduate students. Pre-, intra- and post-operative dat...

Purpose: The aim of this study is to evaluate the effect changes in margin design on stress distribution restoration zirconia-based full-crown restorations using 3D finite element analysis. Material and Methods: To be used restorations, tooth number 16 was prepared chamfer step type a maxillary tooth-jaw model (AG-3: Tipodont, frasaco, Germany). scanned desktop scanner, analysis obtained. Zirco...
