In this study, the effect of flowable composite reinforced with a leno wave ultra high modulus (LWUHM) polyethylene fiber (Ribbond) on fracture resistance of endodontically treated molars with MOD cavity and lingual cuspal fracture was evaluated. Sixty sound extracted human mandibular molars were randomly assigned to six groups (n = 10). Group 1 served as control. Teeth in groups 2-6 received r...

The aim of this study was to compare smile attractiveness between one, three, and four premolar extraction protocols in patients with Class II division 1 subdivision malocclusions and to analyse the aesthetic influence of buccal and posterior corridor widths on smile attractiveness. The sample consisted of posed smile photographs obtained from 66 subjects, divided into three groups according to...

Hypophosphatemic rickets (HR) is a rare hereditary disease in which dental problems in terms of spontaneous periapical infections are frequently reported. Most previous reports have been based on a small number of HR patients and have been published before the disease could be confirmed genetically. The aim of the present study was to describe the periapical and endodontic status of permanent t...

Restoration of endodontically treated teeth is one the major challenges faced in field operative dentistry. In tooth, most part tooth structure lost because dental caries, conventional access cavity preparation and biomechanical during root canal therapy. They become very weak brittle also more prone to fracture compared vital

BACKGROUND Posts are used to enhance crown buildup in pulpless teeth with destructed crown portion. Different types of post are used in endodontically treated teeth. The aim of the present in vitro study was to evaluate fracture resistance of custom made, metal, glass fiber reinforced and carbon reinforced posts in endodontically treated teeth. MATERIALS AND METHODS An in vitro study was carr...

OBJECTIVES The present study was set up to explore (1) a potential association between a person's caries risk profile and the presence or absence of root-filled teeth, and (2) the caries risk in endodontically treated teeth. STUDY DESIGN Two hundred Saudi adults were divided into an Endodontic Group (EG; n = 100), with a minimum of 2 root-filled teeth, and a Non-Endodontic Group (NEG; n = 100...

OBJECTIVES This study compared the fracture strength and survival rate of endodontically treated crowned maxillary incisors with approximal class III cavities and different core build-ups. METHODS Sixty-four caries free human maxillary central incisors were selected for standardized size and quality, endodontically treated and prepared with approximal cavities 3mm in diameter. Group 1 was res...

Background and Aim: The purpose of this study was to evaluate the effect of gutta-percha solvents on fracture resistance of endodontically treated roots. Materials and Methods: A total of 72 decrowned single canal human teeth were used. Eight of specimens were selected as a control group. Thereafter, the specimens were randomly divided into 2 groups (n= 32) according to gutta-percha solvent whi...
